The check valve of power station is suitable for the pipelines of petroleum, chemical, hydraulic and thermal power plants with nominal pressure of pn20.0 ~ 32.0mpa, working temperature ≤ 540 ℃ (including P (57) 170V and working temperature of 570 ℃). Suitable media are: water, oil, steam, etc. is suitable for the pipelines of petroleum, chemical, hydraulic and thermal power plants with nominal pressure of pn20.0 ~ 32.0mpa, working temperature ≤ 540 ℃ (including P (57) 170V and working temperature of 570 ℃). Suitable media are: water, oil, steam, etc.
1. The product is designed and manufactured according to E101 and JB / t3595 standards, with reasonable structure and excellent performance;
2. The middle chamber of the valve adopts pressure self tightening sealing structure. The higher the medium pressure is, the better the sealing performance is;
3. Both ends of the branch pipe are butt welded to meet different requirements of the nozzle;
4. The sealing surface of valve disc and valve seat is made of Stellite cobalt based cemented carbide, which is wear-resistant, high-temperature resistant, scratch resistant and has long service life;
5. High temperature and pressure resistant parts are made of high-quality heat-resistant alloy steel, safe and reliable, stable performance and long service life.
