The branching technique in the market is even more "magic height", which is varied. In addition to special unlocking tools such as “unlocker†and “master keyâ€, steel wire, iron sheet, chewing gum, toy mud and even cardboard can be unlocked. More advanced, you can use the sorghum vibration to unlock at will. Coupled with the proliferation of inferior manufacturing, there is almost no mechanical lock that can't be opened. A good lock is just an extension of the unlock time. Password locks are no exception. Electronic locks can't sit back and relax. In addition to being expensive, once they are affected by environmental factors or computer turmoil, they can't even lock themselves; and decoding is threatening. Make the locks a "frustration choice" that the people rely on and worry about. Some people joked: "Which is only a gentleman, not a villain." Password double cavity stable bead lock active lock cylinder Click here to view all news photos China's lock industry and lock market are facing the squeeze of foreign companies, and foreign locks have flooded into the Chinese market. Hotels , hotels, and warehouses are still relying on imports and are controlled by foreign locks. Domestic cars are still using ordinary locks. In foreign countries, locks are generally more expensive than doors, but the price of our general door locks is only a few tens of dollars, and even a few yuan can buy a lock. The shoddy and high mutual opening rate is restricting the development of the industry. There is a pull gate lock, and the mutual opening rate is almost over 25%. The industry standard is only 0.53 percent. There has also been a strange phenomenon in which the industry is getting bigger and bigger and profits are getting lower and lower. Some experts pointed out: "If the quality and insurance performance of our locks are no longer good, and we will work hard to develop, China's lock market will be lost." At the "3rd China International" Lock Industry Annual Meeting, the relevant parties emphasized that it is necessary to develop China's "lock-up power into a lock-up power." This is the development direction of China's lock industry and the goal of struggle. Password double cavity stable bead lock active lock cylinder Click here to view all news photos In view of the weaknesses and difficulties faced by the locks, it is possible to have a lock with reliable performance and high quality and low price, to solve problems for the public, and to protect the wealth, it is the common voice of the people. "Password double-chamber stable bead lock", ("bead" is a marble), is a lock that should be heard. Its core component, the design of the active lock cylinder, gives the lock a high degree of insurance performance and anti-theft function, making up for the weakness of the lock. This lock core has eight or more level barriers, two or more insurance, twenty to four hundred passwords, twenty to six hundred insertion routes, four to eighteen marbles, and a total of five to seven large groups of codes. The password can be up to more than 10 billion, at least 30,000, and the mutual opening rate can be zero. This lock cylinder is designed with inner and outer chambers (as shown in the diagram) (see attachment): the outer chamber is called the “password insurance zoneâ€. The transform combination of the convex teeth is the composition of the password. Each tooth plate cavity has at least one convex tooth, usually three to four convex teeth. There are two hundred to four hundred sets of such passwords composed of convex teeth. Each key plate has a notch corresponding to the convex tooth. After the key enters the outer cavity, it must be turned at an angle to enter the inner cavity. This forces the key plate to pass the "validation" of the cryptographic teeth at the aisle of the outer cavity. If the switch cannot pass, the cavity cannot be inserted. The convex tooth is hidden behind the first keyhole and it is impossible to see its distribution at all. The inner cavity is called a "maze." It is the heart of the activity lock cylinder, and the marbles are deeply hidden in this "maze" and completely blocked. It is called a "maze" because it has more than twenty to six hundred insertion routes, which are complicated and varied. If it is a single spoon cavity (as shown in the attached diagram 2): it has three insertion routes, plus a combination of the intermediate cavity convex tooth misalignment, can form twenty-four roads. If it is two to four spoon chambers, plus a complex combination of intermediate cavities, hundreds of ways can be formed. The marble group can also range from four groups of single chambers to nine groups of two chambers to eighteen groups of four chambers. Plus the key base can also form a barrier combination. In this way, there are five to seven groups of arrangement codes that can be arranged by passwords, routes, marbles, and the like. There are more than 30,000 to more than one billion passwords. The general password of locks in China is generally around one thousand, and the requirements of the Ministry of Public Security: the number of high-lock locks should reach more than 60,000. It can be seen that the password of the "password double cavity stable bead lock" is not accessible by any lock. The biggest weakness of mechanical locks is that the insertion holes, together with the bad shape of the insertion holes and the marbles are exposed to the outside, can be inserted, and the route is obvious. However, this is not the case with the "password double cavity stable bead lock". Its first locking hole is at an angle to the second locking hole. The first keyhole limits the direction in which the key is inserted, ensuring that the key must first pass the "verification", and also covers the orientation of the cryptographic teeth, and further obscures the bad path of the second keyhole. The most important thing is to completely cover the marble mechanism. Behind the "maze" that has been reduced by the keyhole deformation, any foreign matter cannot be directly passed through the first keyhole to reach the marble. In addition, the intermediate cavity convex teeth are misaligned with each other, and the curved gap formed by the displacement of the upper and lower key plate cavities is not able to pry into the inner cavity structure, and in the case that the outer cavity convex teeth are blocked, any sheet cannot enter. Inner cavity. This is the safest design for this active lock cylinder. Another equally important design is the design of fragile connections. When using the "unlocking tool" to enter the inner cavity, attempting to use the violent destruction of the lock cylinder, if you want to directly push the twisted piece to unlock, or forcibly twist the marble, as long as the violence exceeds the torsion of the weak part, the vulnerable part will automatically Twisted, the lock cylinder could not be removed. If a hand drill is used , the fragile part will rotate with the drill bit and cannot be drilled, effectively protecting the marble structure of the inner cavity. The original key can still be unlocked. Even if high-frequency vibration is used, the upper and lower marbles will move up and down simultaneously with the vibration direction, and the upper and lower marbles cannot be reached at the same time. This is the reason why this lock has extremely high insurance performance. This lock cylinder not only has a combination of several lock core safety functions, but also blocks each other and protects each other, and the insurance factor is extremely high. Not as good as electronic locks. Overcome the shortcomings of "mechanical locks are not insured and electronic locks are too expensive." It is a high-end patented product that is upgraded by mechanical locks. When made into a security door lock, it can also be swapped with the current home door lock. This lock is most suitable for the manufacture of anti-theft locks such as anti-theft door locks, car locks, safe locks, anti-theft locks, warehouse locks and other high-end property. And the process is not complicated and the cost is low. It is a "guardian" of the mass economy, practical and reliable. It brings peace to the order of security, adds a guarantee to stability and harmony, adds a security to the community, and injects vitality into social development. Although the invention project is still in the stage of seeking patent transfer, I believe that as long as the entrepreneurs and people of insight are eye-catching, once the products are launched into the market, the social effects will be particularly good. This lock cylinder is stocked with physical and assembled demonstration items. This lock cylinder can be combined with any lock, especially high-lock locks. It is a process technology slightly higher than the ordinary lock core, the key parts can be produced in batches, and the assembly operation is simple (please do not disclose the key technical content). Generally, the lock equipment enterprise can basically produce the equipment without using investment equipment. The scale of investment can be large or small. The cost is two to four times that of the ordinary lock cylinder. It can be different in cost depending on the processing method and the type of raw materials. The order is different, but the anti-theft performance is unchanged, which can adapt to the needs of internal and external sales and different consumer groups. , flexible investment. Enterprises, investors can easily accept the premise, transfer patent rights, any form and price can be negotiated.
Ball valve is evolved from the plug valve, its opening and closing parts as a ball, using the ball to rotate 90 degrees around the axis of the stem to achieve the purpose of opening and closing, the difference is that the cock body is a ball, with a circular through hole or channel through its axis. The ratio of the sphere to the passageway should be such that when the ball is rotated 90 degrees, the inlet and outlet should be completely spherical, thus cutting off the flow.
The role of ball valve in the pipeline is mainly used to cut off, distribute and change the direction of media flow, designed into the V-shaped opening ball valve also has good flow regulation function.
Ball valve is not only simple in structure, good sealing performance, but also in a certain nominal range of small volume, light weight, less material consumption, small installation size, and driving torque is small, easy to operate, easy to realize rapid opening and closing, is one of the fastest developing valve varieties in recent decades. Especially in the United States, Japan, Germany, France, Italy, West, Britain and other industrial developed countries, ball valves are widely used, the variety and number of use is still continuing to expand, and to high temperature, high pressure, large mouth, high sealing, long life, excellent regulatory performance and a valve multifunctional direction, its reliability and other performance indicators have reached a higher level, And has partially replaced Gate Valve, Globe Valve, Regulating Valve.

Discussion on the advanced insurance performance and practicality of password double cavity stable bead lock
Locks are the most dependent on the property protection of all walks of life in the society. But the degree of insurance for locks is the most worrying. The weakness of the lock is that the electronic lock is either affected by factors such as power failure, weak current, humidity, etc., or is decoded by the decoder; the computer also has a disorder. The weakness of the lock is more: the lock hole is straight, the bullet is exposed, the keyhole is obvious, the obstacle setting is too small, the structure is simple, the password is low, the mutual opening rate is high, and it is easy to be stolen.
