The ball of the floating ball valve is floating, and under the action of medium pressure, the ball can produce a certain displacement and press tightly on the sealing surface of the outlet end to ensure that the outlet end is sealed. The structure of the pipe welded ball valve is simple, good sealing, but the ball bears the load of the working medium is all passed to the outlet sealing ring, so it is necessary to consider whether the sealing ring material can withstand the working load of the ball medium, and the ball may be offset when the pipe welded ball valve is subjected to higher pressure impact. This structure is suitable for small caliber production and is generally used for medium and low pressure ball valves. The floating ball valve made of stainless steel also has good acid resistance and corrosion resistance. The main characteristics of the steel pipe welding ball valve are its compact structure, reliable sealing, simple structure, easy maintenance, the sealing surface and the sphere are often in a closed state, not easy to be washed away by the medium, easy to operate and maintain, suitable for water, solvents, acids and natural gas and other general working media, but also suitable for poor working conditions of the medium, such as oxygen, hydrogen peroxide, methane and ethylene, etc. Applications in various industries. Ball valve body can be integral, can also be combined.
Steel pipe welding ball valve product application:
1, no need for maintenance, adjustment and lubrication, easy to install, reliable operation under low operating costs;
2, the valve stem can be extended, easy to heat preservation;
3, the operation handle can be removed, reversing installation;
4, the valve body does not contain heavy and unreliable castings;
5, the installation of regulating mechanism, very simple.
Steel pipe welding ball valve technical features:
1, body structure integral welding, there will be no external leakage phenomenon.
2, the valve seat is composed of PTFE sealing ring and spring to pressure and temperature changes have strong adaptability, will not produce any leakage within the scope of use.
3. The anti-leakage structure of the valve stem, the bottom of the valve stem has a PTFE self-sealing gasket and an O-ring, which is composed of 2 O-rings and two PTFE gaskets to ensure no leakage.
4, the valve body material is the same as the pipe material, there will be no uneven stress, and it will not be squeezed and deformed due to earthquake and vehicle passing through the ground.
5, the body is light and easy to keep warm.
6, directly buried ball valve can be directly buried in the ground, no need to build a tall valve well, just set a small shallow well on the ground, saving construction costs and engineering time.
7. The length and stem height of the valve body can be adjusted according to the construction and design requirements of the pipeline.
8, the processing accuracy of the ball is very precise, light operation, no bad interference.
10, there are two kinds of welding and flange connection.
11, operation mode: handle, gear (vertical/horizontal)
12, in the case of normal operation of the valve, it can be used for 20 years.
