Description

Technical Field

[0001] The utility model relates to the field of ball valves, in particular to a C-type ball valve which is easy to replace. Background Art

[0002] The working principle of the C-type ball valve is as follows: when the ball valve is rotated 90 degrees, the inlet and outlet present a spherical surface, thereby closing the valve and cutting off the flow of the medium; when rotated back 90 degrees, the inlet and outlet present a spherical mouth, thereby opening the flow with low flow resistance. The C-type ball valve adopts an eccentric design, which produces a wedge effect and torque sealing. When closing, the C ball moves gradually relative to the valve seat and disengages instantly when opening, with low movement resistance. The C-type ball valve has the advantages of wear resistance, self-cleaning crystals, fast shut-off, corrosion resistance, anti-jamming, and low torque, making it suitable for a variety of industrial fields. It has low fluid resistance, quick and easy opening and closing, good valve seat and stem sealing performance, long service life, and can be configured with a variety of drive mechanisms to achieve remote control and automated operation.

[0003] When installing a C-type ball valve, the following scenario is often encountered: the installation space for the C-type ball valve is preset between two pipes. However, during actual installation, due to the inconsistency of the lengths of different types of C-type ball valves, the horizontal heights of the water inlet and outlet are also inconsistent. This results in the inability to change the installation form of the ball valve during installation to adapt to the installation conditions of different scenarios. Utility Model Content
