Working principle of Gate Valve
Evolution: Gate Valve evolved from plug valve. It has the same 90-degree rotation action, but the difference is that the plug body is a sphere with a circular through hole or channel passing through its axis. The ratio of the spherical surface and the channel opening should be such that when the ball rotates 90 degrees, the inlet and outlet should all present a spherical surface, thereby cutting off the flow. This type of valve can be installed at any position in the pipeline.
Principle and construction type of Gate Valve
The Gate Valve is a special device that automatically reduces the working pressure of the pipeline. It can reduce the higher water pressure of the pipeline before the valve to the required level of the pipeline after the valve. Universal Valve are widely used in high-rise buildings, areas with excessively high water pressure in urban water supply networks, mines and other occasions to ensure that each water point in the water supply system obtains appropriate service water pressure and flow.

There are many outlet pressure specifications, generally, and the high outlet pressure is. (2) When installing the Gate Valve, you should determine whethe
A brief discussion on Gate Valve common sense and its application in thermal systems of power plants
There are a large number of pipelines in thermal systems of power plants, and these pipelines have different uses. If each pipeline and the connected equipment are to meet the operation needs of the thermal system, it is necessary to scientifically select the valve to be used. According to the function of the system, the appropriate valve should be selected to connect between the pipeline and the equipment, so as to meet the needs of the system function. Based on many years of experience, here is some common sense about Universal Valve, and which systems can be used in thermal systems of
Introduction to the subdivision and differences of Gate Valve
A Gate Valve is a safety protection valve for a closed system. Its opening and closing parts are in a normally closed state under the action of external forces. When the medium pressure in the closed system increases and exceeds the specified value of the Gate Valve, it automatically opens and discharges the medium to the outside of the system to reduce the system pressure to prevent the damage of the high-pressure system in the system. Universal Valve belong to the automatic valve category and are mainly used in boilers, pressure vessels, air conditioners, and solar energy pipelines to c
Installation and use of Gate Valve
1. Before installing the Gate Valve, check the valve cavity and sealing surface, and do not allow dirt or sand to adhere; 2. The bolts of each connection part of the Gate Valve must be tightened evenly; 3. Check the Universal Valve packing parts and tighten them to ensure the sealing of the packing and the flexible
Correct identification of Gate Valve
The opening and closing parts of the Gate Valve are plug-shaped discs, the sealing surface is flat or conical, and the disc moves linearly along the center line of the fluid. The movement of the valve stem can be either lifting rod type or lifting rotating rod type. Universal Valve are only suitable for full opening and full closing, and adjustment and throttling are not allowed.
What are the main reasons for Gate Valve to have high reliability?
(1) The smooth channel inside the Gate Valve is more suitable for conveying viscous fluids, slurries, and solid particles. (2) Because it will not get stuck during operation (when there is no lubricant), it can be reliably used in corrosive media and low-boiling liquids. (3) The ball-type closing me
What types of Gate Valve can be classified according to their structural forms?

Applicable occasions of Lifting Stem Ball Valve/track Ball Valve
Lifting Stem Ball Valve/track Ball Valve usually uses nylon and polytetrafluoroethylene as valve seat sealing ring materials, so its use temperature is limited by the valve seat sealing ring materials. The shut-off effect of the ball valve is achieved by the metal ball being pressed against the plastic valve seat under the action of the medium. Under a certain contact pressure, the valve seat sealing ring undergoes elastic-plastic deformation in local areas. This deformation can compensate for the manufacturing accuracy and surface roughness of the ball and ensure the sealing performance
