Ball valve advantages

Advantages: ① has the lowest flow resistance (actually 0); ② can be reliably used in corrosive media and low-boiling liquids because it will not get stuck during operation (when there is no lubricant); ③ in larger Within the range of pressure and temperature, it can be completely sealed; ④ It can realize rapid opening and closing, and the opening and closing time of some structures is only 0.05~0.1s, so as to ensure that it can be used in the automation system of the test bench. When the valve is opened and closed quickly, there is no shock in operation. ⑤The spherical closure can be automatically positioned at the boundary position; ⑥The working medium is reliably sealed on both sides; ⑦When fully open and fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, so the medium passing through the valve at high speed will not be Cause erosion of sealing surface; ⑧ compact structure and light weight, it can be considered as the most reasonable valve structure for low temperature medium system; ⑨ symmetrical valve body, especially the welded valve body structure, can well withstand the stress from the pipeline ; ⑩ The closing part can withstand the high pressure difference when it is closed. ⑾The ball valve with fully welded valve body can be directly buried in the ground, so that the valve internals are not corroded, and the maximum service life can reach 30 years. It is the most ideal valve for oil and natural gas pipelines.
