Valve sealing requirements

The sealing performance of a valve refers to the ability of each sealing part of the valve to prevent medium leakage. It is the most important technical performance indicator of the valve.

Valve daily maintenance

Pay attention to the storage environment of the valve. It should be stored in a dry and ventilated room, and both ends of the passage should be blocked.

Valve cleaning steps

According to the processing requirements, some parts need to be polished, and there should be no processing burrs on the surface;

Valve performance testing requirements

Detection of the flow resistance coefficient of the valve under pipeline water transmission conditions.

Valve specification requirements

The valve model should indicate the national standard number requirements based on it. If it is an enterprise standard, the relevant description of the model should be indicated.

Valve assembly requirements

The installation workshop must be kept clean, or a temporary clean area must be built, such as using newly purchased colored strips of cloth or plastic film, to prevent dust from entering during the i

Valve installation requirements

Before installing the valve, carefully check whether the model and specifications of the valve used are consistent with the design;

Valves are classified according to their functions and uses

This type of valve has the function of opening and closing. It is often installed on the inlet and outlet of cold and heat sources, the inlet and outlet of equipment, and branch lines of pipelines (in

Introduction to valves

Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveyed medium.

Introduction to gas valve

The gas valve is a new type of safety supporting device for gas pipeline engineering. It is used to cut off, connect and regulate the gas in the pipeline.

Precautions for installing electric stop valve

When installing the valve, pay attention to the flow direction of the medium and install it strictly in the direction indicated by the valve flow arrow.

Structural features of electric stop valve

No friction in opening and closing. This function completely solves the problem of traditional valves affecting sealing due to mutual friction between sealing surfaces.
