Introduction to Power Station Check Valves:
Power station check valves produced by Shanghai High Pressure Valve Factory are suitable for pipelines in various working conditions such as petroleum, chemical industry, and thermal power stations with Class1500～2500Lb and operating temperature ranging from -29℃ to 570℃. Applicable media include water, oil, steam, etc. The valve cavity of the power station check valve adopts a pressure self-tightening sealing structure, and the higher the cavity pressure, the better the sealing performance. Both ends of the branch pipe are butt-welded, adapting to different pipe connection requirements.
The main materials are carbon steel, chrome-molybdenum steel, chrome-molybdenum-vanadium steel, austenitic stainless steel, etc.; power station valve products are applied to pipelines in various working conditions of thermal power plants. Operation modes: manual, electric, pneumatic, gear transmission, etc. Yongjia Guohao Valve always adheres to the strategy of "technology first, quality leading, technological innovation". The power station valve products it produces have compact and novel structures, reasonable material selection, and mature and advanced technology, which are trustworthy products for users.
Structural Features of Power Station Check Valves:
1. Product design and manufacturing follow ANSI B16.34 and E101 standards, and can be matched with imported equipment.
2. The valve cavity adopts a pressure self-tightening sealing structure, and the higher the cavity pressure, the better the sealing performance.
3. Both ends of the branch pipe are butt-welded, adapting to different pipe connection requirements.
4. High-temperature pressure-resistant parts of the valve are made of high-quality heat-resistant alloy steel, with good high-temperature performance, high pressure resistance, durability, safety and reliability.
5. The sealing surfaces of the valve disc and valve seat are surfaced with stellite cobalt-based hard alloy, which is wear-resistant, high-temperature resistant, has good scratch resistance and long service life.
6. The valve disc rotates around the pin shaft outside the valve seat, reducing violent impact during closing.
7. The built-in pin shaft structure reduces external leakage points, making it more reliable in use.
