The high pressure ball valve has a motion of 90 degrees of rotation, the body of the plug is a sphere, with a circular through hole or passage through its axis. The valve ball valve is important in the pipeline for the active deflection of the intercepting, dispatching and changing medium. It only needs to be rotated by 90 degrees and the small rotating torque can close the precision. The ball valve is suitable for switching and blocking valves, but the growth of the ball valve has been planned to save and control the flow, such as a V-type ball valve. Let's take a look at the principle and strengths of the high pressure ball valve with the valve.
The important features of the high-pressure ball valve are its compact layout, easy sealing, simple layout and convenient maintenance. The sealing surface and the spherical surface are often closed, which is not easily eroded by the medium, easy to operate and maintain, and is used for water, solvent, acid and natural gas. The same thing is usually the medium, and it is also used in mediums with harsh conditions, such as oxygen, hydrogen peroxide, methane and ethylene, which are widely used in various industries. The ball valve body can be either a group or a combination.
High pressure ball valve strengths:
1. The fluid resistance is small, and the full-diameter ball valve has no flow resistance at all.
2. The ball valve produced by the valve has simple layout, small size and light weight.
3. Valve performance, precision available. It has two sealing faces, and now the sealing surface material of the ball valve is made of various plastics, and the sealing property is good, and the sealing can be completely completed. It has also been used throughout the vacuum system.
4. Easy to operate, open and close agile, from full opening to full closing, just rotate 90, which is convenient for remote interval control.
5. The maintenance is convenient, the layout of the ball valve is simple, and the sealing ring is usually active, and the disassembly and replacement are more convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat of the valve is cut off from the medium, and the medium passage period will not cause corrosion of the sealing surface of the valve.
7. Wide range of applications, from small to a few millimeters, up to a few meters, from high vacuum to high pressure can be applied.
8. Since the ball valve has wiping property during the opening and closing process, it can be used in a medium with suspended solid particles.
High pressure ball valve classification and features:
Ball valves are divided into: floating ball valve, solid ball valve, track ball valve, V ball valve, three-way ball valve, stainless steel ball valve, forged steel ball valve, ash ball valve, anti-sulfur ball valve, three-way ball valve, pneumatic ball valve, electric ball valve, ferrule Ball valve, welded ball valve.
According to the shell/body material classification, the ball valve can be divided into:
1. Metal material valves: such as carbon steel valves, alloy steel valves, stainless steel valves, cast iron valves, titanium alloy valves, Monel valves, copper alloy valves, aluminum alloy valves, Sichuan valves, lead alloy valves, etc.
2. Metal valve body lining valve: such as rubber-lined valve, lining fluorine valve, lining lead valve, lining plastic valve, lining valve.
3. Non-metallic material valves: such as ceramic valves, glass valves, plastic valves.
