The introduction of ball valve

  Ball valve, ball valve in the field of Marine engineering and ship should stop valve), the standard of GB/T21465-2008 "valve terms" is defined as: opening and closing (sphere) driven by the valve stem, and around the axis of rotation movement of the valve stem.Use can also be used on regulation and control of fluid, the "V" ball valve, hard seal the v-shaped ball core of carbide surfacing with strong shear force between metal valve seat, especially suitable for fiber, micro solid material such as medium.And ball valve in the pipeline is not only more connected to the confluence of flexible control medium, shunt, and the flow switch, at the same time also can close any channel and make the other two.This valve shall generally be installed in the pipeline.Classification of ball valve, pneumatic ball valves, electric ball valves, manual ball valve.
  Ball valve is 90 degrees of rotation movement, the cock body is a sphere, a round hole or tunnel through its axis.Ball valve in the line is mainly used for cutting, distribution, and change the flow direction of medium, it just has to rotate 90 degrees of operating and small rotational torque can be closed tightly.Ball valve is suitable to do the most switch, cut-off valve, ball valve but recent development have designed to make it with throttling and control flow, such as V type ball valve.
  Ball valve itself is the main characteristics of compact structure, reliable sealing, simple structure, convenient maintenance, sealing surface and the spherical often in the closed state, not easily be medium erosion, easy operation and maintenance, applicable to water, solvent, acid and gas, such as general work medium, but also is suitable for the working conditions of media, such as oxygen, hydrogen peroxide, methane and ethylene, widely used in various fields.Ball valve body can be a whole, also can be combined.
  Ball valve points are: the floating ball valve, the fixed ball ball valve, track ball, v-shaped ball valve, three-way ball valve, stainless steel ball valves, forged steel ball valve, sulfur discharge ball valve, ball valve, pneumatic ball valves, electric ball valves, card sets of ball valves, welding ball valve.
According to the shell/classification, the main valve can be divided into:
1. Valve: metal materials such as carbon steel, alloy steel, stainless steel valve, cast iron valve valve, the titanium alloy valve and monel valve, copper alloy, aluminum alloy, lead alloy valve valve valve, etc.
2. The metal valve body lining: such as rubber lining, fluorine-butterfly valves, valve lining lead, lining plastic valves, valve lining enamel valve.
3. Valve non-metallic materials: such as ceramic, glass, plastic valve valve.
