The direction of the valve industry development---2009-11-10
With the continuous development of science and technology, the domestic valve market, but also to the high-tech, high-parameter, strong corrosion resistance, high-life direction. Based on the analysis of valve technology at home and abroad, and domestic and international valve market demand analysis, obtained in recent years, various industries use high-tech valve and valve industry development trend and investment direction, are as follows:
1. Oil, natural gas wellhead valve devices
Oil, natural gas wellhead valves are mainly used in the U.S. API 6A standard single-gate or Shuangzha board, there is diversion holes with or without diversion hole Forged parallel gate valve, slurry valve, angle-type throttle valve (CHOKE valve), pilot-type safety valve and check valve.
The valve nominal pressure level of API 2000psi, 3000psi, 5000psi, 10000psi, 15000psi, 20000psi; nominal diameter of DN46 Works ~ 228mm (113/16in ~ 9in); the temperature rating of K (-60 ~ 182 ¡æ), L (-42 ~ 182 ¡æ), P (-29 ~ 182 ¡æ), R (room temperature), S (-18 ~ 166 ¡æ), T (-18 ~ 182 ¡æ), U (-18 ~ 121 ¡æ), V (2 ~ 121 ¡æ); material requirements for the AA, BB, CC, DD, EE, FF, HH; material performance requirements by 36K, 45K, 60K, 75K; product technical requirements by PSL1 (product specification grade 1), PSL2 ( product specification grade 2), PSL3 (product specification grade 3), PSL4 (product specification grade 4).
2. Oil, natural gas long-distance pipeline with the valve
Oil, gas, long-distance pipeline is mainly in line with the United States with the valve API 6D standard single-gate or Shuangzha board, there is diversion with or without diversion hole parallel holes Forged Gate Valve; forged or cast steel three-bodied, upload type or all-welded-mounted ball valves; oil seal or pressure-balanced plug valve; Swing or butterfly valve, pass the ball valve; pigging valve.
The valve nominal pressure level of CL150 (PN2.0MPa), CL300 (PN5.0 MPa), CL400 (PN6.4MPa), CL600 (PN10.0MPa), CL900 (PN15.0MPa), CL1500 (PN25.0MPa) , CL2500 (PN42.0MPa); nominal diameter of DN50 ~ 1500mm (2in ~ 60in); resistance test the technical requirements according to ISO10497; valve pressure test according to ISO5208.
3. Nuclear Valves
Valve than conventional nuclear power with a large thermal power station with its technical characteristics and requirements of the valve is higher. Valves are generally gate valve, globe valve, check valve, butterfly valve, safety valve, main steam isolation valves, ball valves, diaphragm valves, pressure reducing valve and control valves, etc.; a representative of the valve the highest technical parameters are: Maximum diameter DN1200 mm (core 3 of the butterfly), DN800 mm (core 2 of the main steam isolation valve), DN350 mm (the nuclear one of the main circuit gate valve); the maximum pressure: approximately 1500 lbs level; maximum temperature: is about 350 ¡æ; medium: cooling agent (diboride water) and so on. The production of nuclear grade valve provision requires products: usually by the nuclear industry standards EJ, the U.S. ASME, IEEE standards and the French pressurized water reactor nuclear island of machinery and equipment design and construction of RCC-M and other rules.
The development of nuclear power with the specific type of valve, the parameters are as follows:
¢Å no stuffing of the gate valve:
a hydraulic-driven gate valve. The valve piston with its own pressure water to promote open or closed, the valve Nominal diameter: DN350, 400 mm; working pressure: PN17.5MPa; operating temperature: 315 ¡æ.
b-wide closed electric gate valve. The valve should be closed using a special screen motor, through immersion in the work of planetary reducer for institutions to make damper open and close movement. The valve Nominal diameter: DN100 ~ 800 mm; working pressure: PN2.5 ~ 45.0MPa; operating temperature: 200 ~ 500 ¡æ.
