Ball valve and sealing ring

Seals, also known as sealing rings (gaskets), etc., involve a very wide range of industries, ranging from electronics industry, automobile industry, small household appliance industry, digital product industry (mobile phone industry, etc.),  as large as military-specific seals, shipbuilding, aviation, and larger construction machinery industries. Seals (gaskets) may come into contact everywhere in our lives.

 Just like the flower hair in our water heater, there is a small sealing gasket, which mainly plays the role of sealing water (if you don't have it, your water heater will not be able to heat up). The mobile phones we use also use sealing gaskets. Without the sealing gaskets, a lot of dust will run into the inside of your mobile phone. So little seals are lifted in our lives pivotal role.

Ball valve, the standard GB/T21465-2008 "Valve] Terminology" is defined as: the opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve.

valve.

Ball valve  - - is evolved from a cock. Its opening and closing parts are used as a sphere, and the sphere is rotated 90o around the axis of the valve stem to achieve the purpose of opening and closing. Ball valve on the pipeline

It is mainly used to cut off, distribute and change the flow direction of the medium, and the ball valve designed with a shaped opening also has a good flow adjustment function. The ball valve not only has a simple structure and good sealing performance, but also

And within the nominal pass range, the volume is small, the weight is light, the material consumption is small, the installation size is small, and the driving torque is small, the operation is simple, and it is easy to realize rapid opening and closing. The ball valve is nearly a dozen.

Valve varieties developed over the years.

Especially in the developed industries such as the United States, Japan, Germany, France, Italy, the West, and the United Kingdom, the use of ball valves (ball valve seals) is very extensive, and the variety and quantity of use continue to expand.

It develops in the direction of high temperature, high pressure, large diameter, high sealing, long life, excellent adjustment performance and multi-function valve, and its reliability and other performance indicators have reached a high level.

And has partially replaced gate valve, globe valve, throttle valve. With the technical progress of ball valves, in the foreseeable short-term, especially in oil and gas pipelines, oil refining crackers

There will be wider applications in the nuclear industry. The ball valve is mainly used to cut off or connect the medium, and can also be used for the regulation and control of the fluid. The v-type ball valve can carry out relatively accurate flow

regulation and control, while the three-way ball valve is used to distribute the medium and change the flow direction of the substance.
