【Valve Sealing Ring】Ball Valve And Sealing Ring
Dec 11, 2021
Seals, also known as sealing rings (gaskets), etc., involve a wide range of industries, ranging from the electronics industry, the automotive industry, the small household appliance industry, the digital product industry (mobile phone industry, etc.), to the national military-specific Seals, shipbuilding, aviation, super-large construction machinery industry, etc. We may touch seals (gaskets) everywhere in our lives. Just like the shower head in our water heater, there is a small sealing gasket, which mainly plays the role of sealing the water (if you don't have it, your water heater will not be able to heat up). In addition, 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 small seals play a pivotal role in our lives.
Ball valve, the standard GB/T21465-2008 valve terminology is defined as: a valve whose opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve
The ball valve is evolved from the plug valve. Its opening and closing part is used as a sphere, and the sphere is rotated 90 degrees around the axis of the valve stem to achieve the purpose of opening and closing. The ball valve is mainly used to cut off, distribute and change the flow direction of the medium on the pipeline. The ball valve designed with V-shaped opening also has a good flow adjustment function. The ball valve is not only simple in structure and good in sealing performance, but also small in volume, light in weight, low in material consumption, small in installation size, and small in driving torque within the nominal diameter range. It is easy to operate and easy to open and close quickly. 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 are still expanding. The tightness, long life, excellent adjustment performance and multi-function development of the valve, its reliability and other performance indicators have reached a high level, and have partially replaced gate valve, globe valve, throttle valve. With the technological advancement of ball valves, it will be widely used in oil and gas pipelines, oil refining crackers and the nuclear industry in the foreseeable short term. 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-shaped ball valve can carry out relatively accurate flow regulation and control, while the three-way ball valve side is used to distribute the medium and change the flow direction of the medium.
