H64Y Power Station Check Valve

Follow times: Release time: 2015-03-27

Product Usage:

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.

Product structure characteristics

1. The product is designed and manufactured according to ANSIB16.34 and E101 standards, and can be equipped with imported equipment.

2. The middle cavity of the valve adopts a pressure self-tight seal structure. The higher the pressure in the inner cavity, the better the sealing performance. The two ends of the branch pipe are 3. The two ends of the branch pipe are butt welded to meet different requirements of the connection.

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

5. The sealing surfaces of the valve disc and the valve seat are made of stellite cobalt-based hard alloy, which is hard-wearing, high-temperature resistant, good abrasion resistance and long service life.

6. The valve disc rotates around the pin outside the valve seat, reducing violent impact when closing.

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

Application range of power station check valve:

Power station check valve is suitable for pipelines of various working conditions such as petroleum, chemical and thermal power stations with Class 1500 ~ 2500Lb and working temperature -29 ~ 570 ℃. Applicable medium: water, oil, steam, etc.

The installation of check valves in power stations should pay attention to the following:
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.
