American standard high temperature and high pressure power station rotary check valve
Follow times: Release time: 2015-04-30
The butterfly check valve is straight-through. The above types of check valves can be divided into three types: screw connection, flange connection and welding. Also belongs to the check valve category. The opening and closing parts rely on the flow of the medium and the force to open or close by itself, and the valve to prevent the medium from flowing backward is called a check valve. Non-return valve is an automatic valve. It is mainly used for pipelines where the medium flows in one direction. It only allows the medium to flow in one direction to prevent accidents.

Design Standard: API6D, BS1868 Sealing Form: Hard Seal Processing Custom: Yes American Standard Power Station Check Valve Product Use:
The American standard power station check valve is suitable for pipelines of various working conditions such as petroleum, chemical and thermal power stations with Class1500 ~ 2500Lb and working temperature -29 ~ 570 ℃ Applicable medium: water, oil, steam, etc.
Welded check valve is suitable for petroleum, chemical, hydraulic, thermal power stations and other working conditions with a nominal pressure of PN20.0 ～ 32.0Mpa and an operating temperature ≤540 ° C (among which P (57) 170V operating temperature is 570 ℃) In the pipeline, cut off or connect the medium. Applicable medium: water, oil, steam, etc.
American standard H64H high temperature power station check valve product structure features:
1. The product is designed and manufactured according to the standards of E101 and JB / T3595-93, with reasonable structure, excellent performance and shape.
2. The middle cavity of the valve adopts a pressure self-tightening seal structure. The higher the medium pressure, the better the sealing performance.
3. The two ends of the branch pipe are butt welded to meet different requirements of the pipe.
4. The sealing surfaces of the valve disc and valve seat are made of stellite cobalt-based hard alloy, which is hard-wearing, high-temperature resistant, good anti-scratch performance and long service life.
5. High-temperature and pressure-resistant parts are made of high-quality heat-resistant alloy steel, which is safe and reliable, stable in performance, and long in service life.
The installation of check valve of American standard H64H high temperature power station should pay attention to the following matters:
1. Do not allow the check valve to bear the weight in the pipeline. Large check valves should be independently supported so that they are not affected by the pressure generated by the piping system.
2. Pay attention to the direction of medium flow during installation should be consistent with the direction of the arrow on the valve body.
3. Lifting vertical flap check valve should be installed on vertical pipeline.
4. The lifting horizontal flap check valve should be installed on the horizontal pipeline.
