Main features
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,It is widely used in various industries.The ball valve body can be integral or combined.
 

function of ball valve

The main function of the ball valve is to cut off the flow, distribute the velocity of flow and change the direction of flow, it can rotate 90 degrees.Ball valves have many functions. They can also be used as switches.In China, ball valves are widely used in petroleum refining, long-distance pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, occupies a pivotal position in the national economy.It has a rotation of 90 degrees, the plug body is a sphere, with a circular through hole or channel through its axis.Ball valve in the pipeline is mainly used to cut off, distribution and change the direction of the flow of the medium, it only needs to rotate 90 degrees of operation and a small rotational torque can be closed tightly.Ball valve is most suitable for switch, cut-off valve use, V-type ball valve.In addition to the pipe parameters, the electric valve should pay special attention to the environmental conditions of its use. Because the electric device in the electric valve is an electromechanical equipment, its use state is greatly affected by its use environment.Normally, electric ball valve, butterfly valve in the following environment should pay special attention to use.

Structure of ball valve

The sealing property is good, but all the load of the ball bearing the working medium is passed to the outlet sealing ring. Therefore, it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium. When subjected to high pressure impact, the ball may be offset.This structure is generally used in low and medium pressure ball valves.Valve Fixed Ball Ball Valve The ball of a ball valve is fixed and does not move under pressure.Fixed ball ball valve has a floating seat, by the medium pressure, the seat movement, so that the sealing ring tightly pressed on the ball, to ensure sealing.Usually with the ball on the upper and lower shaft bearing, operation torque is small, suitable for high pressure and large caliber valves.

Advantages:

1.Simple structure, small volume, light weight.

2.Small fluid resistance, full diameter ball valve basically no flow resistance.

3.Tight and reliable.It has two sealing surface, and the sealing surface material of the ball valve is widely used in a variety of plastics, good tightness, and can achieve complete sealing.It has also been widely used in vacuum systems.

4.Easy to operate, open and close quickly, from full open to full close as long as the rotation of 90o, convenient for remote control.

5.Easy maintenance, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient.

6.When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium. When the medium passes, it will not cause the erosion of the valve sealing surface.

7.Applicable to a wide range of sizes from small to a few millimeters to a few meters, from high vacuum to high pressure can be used.

8.Because the ball valve in the opening and closing process has a wipe, so can be used in the medium with suspended solid particles.

High processing accuracy, high cost, high temperature is not easy to use, such as impurities in the pipeline, easy to be blocked by impurities, resulting in the valve can not be opened.
