What is the all-inclusive ball valve?

All-inclusive ball valve A valve that is driven by the stem and rotates around the ball valve shaft. It can also be used for fluid regulation and control. The hard sealed V-shaped ball valve has a strong shear force between the V-shaped ball core and the hard alloy surfacing metal seat, especially for the medium containing fiber and small solid materials. The multi-pass ball valve can not only flexibly control the confluence, shunt, and flow switch of the medium on the pipeline, but also close any channel to make the other two channels connected. This type of valve should generally be installed horizontally in the pipe. Ball valves are divided into pneumatic ball valves, electric ball valves and manual ball valves according to the driving mode. Ball valves (ball valves) were born in the 1950s. With the rapid development of science and technology, the continuous improvement of production process and product structure, in just 40 years, it has rapidly developed into the main type of valve. In western industrial developed countries, the use of ball valves has increased year by year.

In China, the ball valve is widely used in petroleum refining, pipeline, chemical industry, paper making, pharmaceutical, water conservancy, electric power, municipal, steel and other industries, plays a pivotal role in the national economy. It has a 90-degree rotation, and the plug body is a sphere with a circular through-hole or channel through its axis.

The ball valve is mainly used to cut off, distribute and change the flow direction of the medium in the pipeline, and it only needs to rotate 90 degrees and a small rotating torque to close tightly. Ball valve used as switch, globe valve, V-type ball valve. In addition to pipeline parameters, the electric valve should pay special attention to the environmental conditions of its use, because the electric device in the electric valve is a mechanical and electrical equipment, and its use status is greatly affected by its use environment. In general, electric all-inclusive ball valves and butterfly valves should be paid special attention in the following environments.

First, wear resistance; Because the hard seal ball valve core is alloy steel spray welding, the sealing ring is alloy steel surfacing welding, so the hard seal ball valve will not produce too much wear in the switch. (Hardness coefficient 65-70):

Second, good sealing performance; Because the seal of the hard seal ball valve is manually grounded, until the spool and seal ring can be fully used. Reliable sealing performance.

Three, optical switch; Because there is a spring at the bottom of the sealing ring of the hard sealed ball valve, the sealing ring is tightly held with the spool, so when the external force exceeds the preload force of the spring, the switch is very light.

Long service life: It has been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as People's Daily life.

Pneumatic ball valve simple and compact structure, reliable sealing, easy maintenance, dense surface and spherical often in a closed state, not easy to be eroded by the medium, easy operation and maintenance, suitable for water, solvent, acid and natural gas and other general working medium, mainly used to cut off or vent the pipeline medium, can also be used for fluid regulation and control.
