Abstract

A ball valve without high-pressure torque is composed of valve body, connecting body, ball, valve rod and valve seat with an oil storage chamber communicated with oil controller. It has high sealing performance and is suitable for liquid delivering pipeline.

Description

technical field [0001] The invention relates to a ball valve, in particular to a torque-free ball valve under high pressure. Background technique [0002] The existing ball valves used on pipelines are usually provided with a worm gear device in order to save labor to open the ball valve, and the ball valve provided with such a worm gear device has a relatively high production cost. In addition, this kind of ball valve with worm gear device has high requirements on the ball due to wear between the valve seat and the ball, and its service life is relatively short. Contents of the invention [0003] The main purpose of the present invention is to design a torque-free ball valve under high pressure. [0004] The invention aims to solve the existing problems of high production cost and short service life of the existing ball valve with a worm gear device. [0005] The embodiment of the present invention is: it comprises valve body, con...
