1. The function and use of self-operated pressure reducing valve
Self-operated pressure reducing valve does not require any external energy and uses the regulated medium to regulate itself. Stress Relief Products. The biggest feature of this product is that it can work in places without electricity and gas, while saving energy. The pressure setting value can be adjusted at will during operation. It adopts quick-opening flow characteristics, sensitive action and good sealing performance, so it is widely used in various industrial equipment such as petrochemical industry, electric power, metallurgy, food, textile machinery, manufacturing and residential buildings to decompress and stabilize the pressure of various gas, liquid and steam media. The self-operated pressure reducing valve produced by Shanghai Bengao Valve Co., Ltd. is not installed alone on the pipeline, but is installed in the system in conjunction with other valves or pipelines. There are usually single-way pressure reduction and dual-way pressure reduction.
2. Issues to note when installing and using self-operated pressure reducing valves
When self-operated pressure reducing valves are used in gas or low-viscosity liquid media, they are usually installed upright. On horizontal pipes, only install them upside down or diagonally when the space does not allow.
When the self-operated pressure reducing valve is used in steam or high-viscosity liquid media, the self-operated pressure reducing valve is usually installed upside down on a horizontal pipe. The condenser (self-operated type for steam) should be higher than the pressure regulating valve. The actuator is lower than the valve before and after taking over. The condenser should be filled with cold water before use and then filled with water about once a month. The pressure point of the self-operated pressure reducing valve should be located at the appropriate position of the pressure regulating valve. The pressure regulation in front of the valve should be greater than twice the pipe diameter, and the pressure regulation behind the valve should be greater than twice the pipe diameter.
In order to facilitate on-site maintenance and operation of the self-operated pressure reducing valve, appropriate space should be left around the pressure regulating valve.
When the medium of the self-operated pressure reducing valve is clean gas or liquid, the filter in front of the valve does not need to be installed.
Self-operated pressure reducing valve The pressure regulating valve should have a fixed bracket when its diameter is too large.
When it is confirmed that the medium is clean, the self-operated pressure reducing valve does not need to be installed.
When the position of the self-operated pressure reducing valve is really not allowed, the bypass valve (manual) can be omitted (we do not recommend it)
The user can choose a check after the self-operated pressure reducing valve group according to needs Valve safety valve etc.
The calculated diameter of the self-operated pressure reducing valve can be smaller than the diameter of the pipeline, while the stop valve, cut-off ball valve, bypass valve and filter cannot be smaller than the diameter of the pipeline.
