Characteristics and Application of Water Seal Gate Valve
Water seal gate valve for nominal pressure PN1.6 ~ 10.0Mpa, operating temperature 0 ~ 425 ℃ thermal power plant backwater condensing system and petroleum, chemical and atmospheric requirements of the pipeline to cut off or connect the media, the applicable medium: water , Oil, steam and non-corrosive gases. First, the characteristics and uses of water seal gate valve 1, S / Z series opening and closing flexible, fast, reliable seal, usually with double gate two-way flexible seal; 2, the product structure is simple, compact and reasonable, easy maintenance, long service life ; 3, in the pipeline for hoist device, must be in full open or fully closed state, may not be used to regulate the flow; 4, the valve connection flange and welding are two ways to drive manual and electric, the structure is more complex . Gate width according to the sealing surface configuration can be divided into wedge gate valve and parallel gate valve, wedge gate valve single gate type, double gate and elastic gate type; parallel gate valve can be divided into single gate type and double Gate type. According to the thread position of the stem division, can be divided into Ming rod valve and dark rod gate valve two. Second, the design and manufacture of water seal valve design and manufacture: GB12234 Flange size: GB9113 JB7490 Pressure Temperature: JB / T74 GB9131 Structure Length: GB / T12221 Butt Weld Size: Inspection and Testing: JB / T9092 GB13927 Third, the main Performance Specifications Nominal pressure (MPa) Shell strength test 1.0 1.6 2.5 4.0 6.4 10.0 Sealing test 1.5 2.4 3.8 6.0 9.6 15.0 Sealing test 1.1 1.8 2.8 4.4 7.0 11.0 Gas seal test 1.1 1.8 2.8 4.4 7.0 11.0 Scope of application Product type Applicable temperature ( ℃) Applicable medium Carbon steel type ≤425 Water, steam, oil, non-corrosive gas Alloy type ≤540 Main parts material Product Type Part Name Valve body, valve cover, bracket Valve stem gate, valve flap, sealing surface Valve Seat Sealing Stem Nut Packing Alloy Steel (I) WCB Cr5Mol 20Cr1Mo1VA Cobalt Base Alloy Carbide Aluminum Bronze Flexible Graphite Carbon Steel Type (C) WCB 1Cr13 or 2Cr13 Cr13 Type Stainless Steel or Carbide Stainless Steel Aluminum Bronze Flexible Graphite
