An electric Gate Valve is a type of valve that uses an Electric Actuator to open and close the gate of the valve. The gate is a flat or wedge-shaped piece that moves perpendicular to the flow of the fluid. When the valve is open, the gate is lifted or pushed aside to allow the fluid to pass through. When the valve is closed, the gate is lowered or pressed against the valve seat to prevent the fluid from flowing.

1. Partial frame: special aluminum profiles, corners, light steel keel, rear baffle (aluminum plastic plate, Ou Song board will do)
2. Display part: cell board. Attachment covers: cable power cords.
3. Partially tampered with: 扼 扼 card, adapter plate, cable. Note! (There is no need for adapter plates and cables for individual cards)
4. Partial power supply: 220V-5V power supply. Commonly used 40A, 30A. It depends on the condition of the work situation.
5. Gadgets: 16P cable, 16P card head and clips, three-core value line, DB9 head (pin, hole) DB9 plastic shell, power cord, self-tapping. Strong magnets (brackets and magnets)
6. Tools: cutting machine, crimping pliers, electric iron, stripping pliers, screwdriver.
Assembling steps to make a display First of all, we must confirm the size of the frame, below I explain the way to cut the border. Take the most common 3.5*90 profiles and P10 cell boards for example. The display volume is 2 * 5 blocks.
1. Confirm the size of the cell board, to be very accurate to millimeters. Take the P10 cell board: Its size is 16cm*32cm.
2. Calculate the net size of the height and width of the cell board in the display screen. For example, the height of the unit board is 2 * 16cm = 32cm wide and 32cm * 5 blocks = 160cm.
3. Subtract 4 mm from the calculated net size. As mentioned above, the net size is 32cm*160cm. Then the aluminum material size should be (32cm-4mm)*(160cm-4mm)=31.6cm*159.6cm. 31.6 and 159.6 are the actual dimensions of aluminum, and the display must be less than 5mm minus 3mm.
4. Use corners and cut-out profiles to use self-tapping to make good arrangements. Thoroughly neatly tidy up the clutter and place it face down.
5. Put the unit board in the direction, not the wrong direction. Where there are pins, be sure to move toward the height of the profile.
6. Place the magnet holder column on the cell plate and broadcast the magnetic plate into the recess of the nursery column.
7. Measure the required length of the light steel keel and cut it well. Put it on the magnet and try your best to get the magnet in the center of the keel to avoid deviations.
8. The keel is self-tapping and the border is even better.
9. Use the cable to unit the unit board and build it into a bridge type. You can't let the cable be buttoned.
10. Fix the power supply to an appropriate location inside the profile. You can confirm where the power is located according to the bottom. The power supply is usually placed on the profile below the exposed screen. Note the insulation from the cell board.
11. Even if there is a power line, the power line cannot recognize the ties. The exposed screen is low-voltage office, but the current is very high. Instead of going all the way along, the full current of a P10 cell board is 4A, which means that a 40A power supply can have ten cell boards. The display screen is connected in parallel, that is, the positive electrode is connected to the positive electrode, the cathode is connected to the cathode electrode, and the common VCC, +5V, and +V are positive electrodes. GND, COM, -V are cathodes. And the positive cathode must not be connected wrong, otherwise it will lead to unit blackboard retirement. Example: A 40A power supply is equipped with 10 unit boards. We can divide it into three pieces and put them together on a power supply at 5V once. Then we put three power supplies on the power supply and finally connect them to the power supply. . In other words, each circuit does not exceed 4 cell boards, so that the line will not be damaged due to excessive current.
12. Place the card on the input of the cell board, and be sure to supply 5V directly from the power supply.
13. The pins of the card are in order. For example, JK1.JK2... or J1.J2...JP1.JP2... The position of the first one needs to be connected to the top of the cell board at the input end of the cell board.
14. The affiliation of the cell board and the tamper block: The letter A of the white color is on the periphery of the general tamper-card pin 1, and the input end of the unit board also has such characters, as long as the two A are parallel platoons. It is accurate.
15. After the above work is done, the sundries in the screen must be completely and tidy to avoid aluminum with conductive end, iron powder, and the end of the thread falling into the circuit board to cause damage to the unit plate.
16. Completely arrange the work done, the power test, the premise is to do a good job of the numerical line. Since most digital control cards are exposed before the value is changed, it is not normal. Therefore, when the power is turned on, it reveals signs of confusion, darkness, bright spots, etc..... Don't need to check whether the positive cathode is connected or not.
17. Numerical wire welding method: The ordinary display only uses two kinds of bottom three. Extension line: This is required for each display. As its name suggests, its utility is to extend the numerical interface of the card to the outside of the screen. Since your display will eventually have to be sealed, you must not change the data once to remove the back cover. The materials he needs are: a long three-wire cable, a DB9 pin, and a DB9 hole. The number 6789 is marked on the top of each welding spot behind the DB9. We only need to have 3 of them on board. These three are 235 needles 2 and holes 2 are welded with one wire in the three wires. 3 and 3 Soldered 5 and 5 Soldered. Afterwards, fix the plastic shell to the end of the needle (because the hole is inside the screen).
The two non-intersecting lines are the same as those for the extended line. The difference is that the two lines that do not intersect are two DB9 holes. Both require plastic casing. The same applies to the staggered lines and the two non-intersecting straight lines. The difference is that two of the staggered lines are connected to the other three of 3 and the other is connected to two of the other. 5 is still connected to 5. The two head plastic housings are also required.
18. The staggered line and the two lines that do not intersect are based on the use of a debit card to vote parallel and still staggered.
19. The rest of the above office work is to adjust, the premise is that the display must be able to adjust the power. Because the market is making adjustments to a lot of card types, I will not mention it.
20. After adjusting for 2-3 days, if there is no problem, you can seal the back cover. In the end it will be delivered!
Cautions 1. The unit board and the card must not receive more than 5V.
2. All lines of the positive cathode must not be connected incorrectly.
3. It is necessary to completely clean up the debris in the clean screen.
4.220V AC is not divided into positive cathodes.
Electric gate valves are commonly used in industrial applications where precise control of the fluid flow is required. They are often used in pipelines, water treatment plants, oil and gas refineries, and chemical processing plants. The electric actuator allows for remote control of the valve, which can be operated from a control room or a computerized system. This makes it easier to monitor and adjust the flow of the fluid, which can improve efficiency and reduce the risk of leaks or spills.
LED display installation production production process
We have to do LED display, we must first get enough materials, today Xiaobian to collect a LED display installation production process, for everyone to explain the necessary materials and display process. A display screen covers part of the outer frame, shows part, partially cuts, partially powered, and small parts.
