What are the structural differences between parallel and wedge valves?
- The structure of globe valve and gate valve. What does this article introduce first?What is parallel gate valve?The sealing cover is parallel to the vertical center line, so the sealing surfaces of the valve body and the gate are parallel to each other. This gate valve is the most common double gate plate, in order to shut down, so that the valve and gate two sealing surface contact closely asked, often used in two ram double sided thrust wedge block. Thus, when the valve is closed, the double side thrust block is contacted with the bottom of the valve body and is gradually stressed.s
Why can't the pressure measuring point be set at the two ends of the gate valve when measuring the resistance loss of the gate valve?
- the valve before the pressure measuring point, distance of valve straight pipe length is 5 times the diameter of the valve after the pressure valve, the distance is 10 times the diameter of straight pipe length.s

What type of flange does it fit with the gate valve?
- According to the welding plate flange, flange material selection of piping material.s
What are the features and uses of the gate valve?
- What is gate valve? What is the purpose of forged steel gate valves? What are the features of forged steel gate valves?Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate valve movement direction perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The gate has two sealing surfaces, and the two sealing surfaces of the most commonly used gate valves form wedge and wedge angles vary with valve parameters. Gate valve drive classification: manual gate valve, pneumatic gate valve, electric gate valve.DefinitionGate valve means the closing of the valve (gate) along the central line of the vertical direction of the valve. The gate valve is mainly used for cutting in the pipeline.The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.Minor force needed for opening and closing.Medium flow is unrestricted.When opening fully, the sealing surface is eroded by the working medium smaller than the cut-off valve.The shape is relatively simple and the casting process is betterValve also has shortcomings:The overall size and opening height are larger. Larger space required for installation.In the process of opening and closing, there is relative friction between the sealing surfaces, which may cause galling.Gate valve generally has two sealing surface, processing, grinding and maintenance to increase some difficulties.s
