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.
Today, Dongsheng mainly briefly explains the sealing topic of valves for everyone!
Check valve refers to the valve that automatically opens and closes the valve flap depending on the flow of the medium itself to prevent the backflow of the medium, also known as cut-off valve, one-way valve, reverse flow valve, and back pressure valve. The check valve is an automatic valve whose main function is to prevent the backflow of the medium, the reverse rotation of the pump and the driving motor, and the discharge of the medium in the container.
Check valves--Headstock piece on media flows and forces open or closed to prevent backflow valve media called a non-return valve.The check valve belongs to the automatic valve category, which is mainly used in the pipeline where the medium flows in one direction, and only allows the medium to flow in one direction to prevent accidents.The check valve is also called a one-way valve or cut-off valve, and the bottom valve of the water pump suction pipe also belongs to the check valve category. A check valve is a valve that automatically prevents the backflow of fluid.
The disc of the check valve is opened under the action of the fluid, and the fluid flows from the inlet to the outlet. When the pressure on the inlet side is lower than that on the outlet side, the valve flap is automatically closed under the action of fluid pressure difference, gravity and other factors to prevent fluid backflow. When the check valve is closed, water hammer pressure will be generated in the pipeline, and in severe cases, it will cause damage to the valve, pipeline or equipment, especially for large-diameter pipelines and high-pressure pipelines, so users should pay great attention.
