H61Y Power Station Check Valve

Power Station Check Valve Product Introduction:

The produced power station check valve is suitable for pipelines in various operating conditions such as petroleum, chemical, and thermal power station valves with a Class1500~2500Lb operating temperature of -29~570 ℃. Applicable media include water, oil, steam, etc. The middle chamber of the check valve in the power station adopts a pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance. The two ends of the branch pipe are connected by butt welding to meet different requirements for connecting pipes.

The main materials are carbon steel, chromium molybdenum steel, chromium molybdenum vanadium steel, austenitic stainless steel, etc; Power station valve products are applied to pipelines under various working conditions in fossil-fuel power station. Operation mode: manual, electric, pneumatic, gear transmission, etc. Yongjia Guohao Valve always adheres to the strategy of "technology first, quality leading, and technological innovation". The power station valve products produced have a compact and novel structure, reasonable material selection, and mature and advanced technology, making them trustworthy products for users.

Structural characteristics of check valves in power plants:

1. The product design and manufacturing are in accordance with ANSIB16.34 and E101 standards, and can be equipped with imported equipment for use.

2. The inner chamber of the valve adopts a pressure self tightening sealing structure, and the higher the inner chamber pressure, the better the sealing performance.

3. The two ends of the branch pipe are connected by butt welding to meet different connecting requirements.

4. The high-temperature and pressure resistant components of the valve are made of high-quality heat-resistant alloy steel, which has good high-temperature performance, high pressure resistance, durability, safety, and reliability.

5. The sealing surfaces of the valve disc and valve seat are made of Stellite cobalt based hard alloy overlay welding, which is wear-resistant, high-temperature resistant, with good scratch resistance and long service life.

6. The valve disc rotates around the pin axis outside the valve seat to reduce violent impact during closure.

7. The built-in pin shaft structure reduces external leakage points and makes it more reliable to use.
