High Pressure Power Station Check Valve
Introduction:
The high pressure power station welded check valve is applicable to the pipelines with nominal pressure of PN20.0~32.0Mpa and working temperature of ≤ 540 ℃ (including P (57) 170V and working temperature of 570 ℃) in various working conditions such as petroleum, chemical, hydraulic and thermal power stations. The medium is cut off or connected. Applicable media: water, oil, steam, etc.
Product structure features:
1. The product is designed and manufactured according to the provisions of E101 and JB/T3595-93 standards, with reasonable structure, excellent performance and shape
2. The middle chamber of the valve adopts a pressure self-tightening sealing structure. The higher the medium pressure, the better the sealing performance
3. The two ends of the branch pipe are connected by butt welding to meet different requirements for connecting pipes
4. The sealing surfaces of the valve disc and valve seat are made of stellite cobalt-based cemented carbide, which is wear-resistant, high temperature resistant, good scratch resistance and long service life
5. High-temperature pressure-resistant parts are made of high-quality heat-resistant alloy steel, which is safe and reliable, with stable performance and long service life
