Working principle of water pipeline branch pressure reducing valve

Working principle of water pipeline branch pressure reducing valve

The working principle of the water pipeline branch pressure reducing valve: The water pipeline branch pressure reducing valve uses the opening of the opening and closing parts in the control valve body to adjust the flow of the medium and reduce the pressure of the medium. At the same time, the opening and closing parts are adjusted by the action of the pressure behind the valve to keep the pressure behind the valve within a certain range, and cooling water is injected into the valve body or behind the valve to reduce the temperature of the medium.

Water pipeline branch pressure reducing valve installation operation and matters needing attention

Water pipeline branch pressure reducing valve installation operation and matters needing attention

Water pipeline branch pressure reducing valve (installation operation and precautions of water pipeline branch pressure reducing valve) Notes for the installation and use of water pipeline branch pressure reducing valve: according to the different adjustable pressure reducing valve required, water pipeline branch pressure reducing valve has many specifications. ≤ inlet pressure mostly, * low inlet pressure is not less than 2.5 times the outlet pressure. There are many export pressure specifications, generally ≤ export pressure. When installing the pressure reducing valve, make sure that its connection specifications are consistent with the cylinder and the connection of the system in use. The pressure reducing valve and the cylinder are connected by hemispherical surface, and the two are completely matched by tightening the nut. Therefore, the two hemispherical surfaces should be kept clean during use to ensure good airtightness. Before installation, high-pressure gas can be used to blow away dust. Materials such as PTFE can also be used as gaskets if necessary.

Nitrogen pressure reducing valve in the installation and maintenance of the need to pay attention to what matters

Nitrogen pressure reducing valve in the installation and maintenance of the need to pay attention to what matters

Nitrogen pressure reducing valve (nitrogen pressure reducing valve in the installation and maintenance of the need to pay attention to what matters) Nitrogen pressure reducing valve is used to control the opening of the opening and closing parts in the valve body to adjust the flow of the medium, and reduce the pressure of the medium. At the same time, the opening of the opening and closing parts is adjusted by the action of the pressure behind the valve to keep the pressure behind the valve. Within a certain range, cooling water is injected into the valve body or after the valve to reduce the temperature of the medium. The characteristic of this valve is to keep the outlet pressure and temperature value within a certain range under the condition of changing inlet pressure. Nitrogen pressure reducing valve in the installation and maintenance of the need to pay attention to what matters: in order to facilitate operation and maintenance, the valve is generally installed upright on the horizontal pipeline. During installation, attention should be paid to make the flow direction of the medium in the pipeline consistent with the direction of the arrow shown on the valve.

Installation instructions for proportional pressure reducing valve

Installation instructions for proportional pressure reducing valve

Proportional Pressure Reducing Valve (Installation Instructions for Proportional Pressure Reducing Valve) Installation instructions of proportional pressure reducing valve: before installing proportional pressure reducing valve, the pipeline should be washed clean and Y-type filter should be installed in front of the valve. due to the small debris in the pipeline, the pressure reducing valve will not be closed tightly, resulting in leakage and failure, resulting in ultra-high static pressure of the pipe network behind the valve. The filter shall be installed on the main pipe and the plug shall be removed to lead the drain pipe with valve to the sewage tank for timely drainage. Proportional pressure reducing valve must be set before and after the gate valve or butterfly valve in order to cut off the water during maintenance.

What are the components of the natural gas pressure reducing valve

What are the components of the natural gas pressure reducing valve

Natural gas pressure reducing valve (natural gas pressure reducing valve has what components) What are the components of natural gas pressure reducing valve: natural gas pressure reducing valve main valve and pilot valve composed of two parts. Pressure reducing valve main valve is mainly composed of valve seat, main valve disc, piston, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the pressure of the adjusting spring, the outlet pressure is changed by the diaphragm sensor, and the flow area of the throttle part of the main valve is adjusted by the opening and closing of the pilot valve to realize the decompression and pressure stabilization function.
