Manual Diaphragm Valve Has Good Sealing And Reliable Operation Performance
Sanitary Diaphragm Valve is a commonly used fluid control device, which is characterized by good sealing and reliable operating performance. This article will introduce the technical characteristics of the manual diaphragm valve and related precautions.
1. Structural characteristics
The manual diaphragm valve is mainly composed of two diaphragms made of elastic materials, inlet and outlet flanges, and central components. Among them, the central component includes upper and lower valve bodies, a joystick, and internal pressure transmission pipes of the equipment.
2. Working principle
When it is necessary to control the flow of fluid, the sleeve is displaced by rotating the joystick to form a closed space between the upper and lower valve bodies to achieve the closed state. In addition, during use, it is necessary to regularly check whether the parts are complete, and clean the contact surfaces as necessary or apply lubricants to ensure normal operation.
3. Precautions
In order to ensure the smooth operation of the manual diaphragm valve and extend its service life, please pay attention to the following aspects:
(1) Avoid flow fluctuations: The inlet and outlet pipe diameters should be reasonably set according to different system requirements to reduce the pressure difference fluctuation rate, and operate strictly in accordance with the maximum working pressure standard.
(2) Correct installation: The operation should be carried out according to the instructions in the product manual, paying attention to the interface standards, flange connection methods, and the surrounding structure of the pipeline system. In addition, during use, the valve must be kept in a vertical direction to avoid fluid leakage or hooking due to tilting.
(3) Regular inspection: The various components of the manual diaphragm valve need to be regularly maintained and inspected, including cleaning, replacement of sealing rings and tightening screws. In addition, when the equipment is not in use, the internal hydraulic pressure of the equipment should be released and the silicone O-ring between the reinforcing plate and the jacket should be specially treated to ensure future use.
In short, the manual diaphragm valve is a common control device with good sealing performance and reliable operating performance. It needs to be carefully inspected before use and properly maintained and operated in accordance with relevant requirements.
