Abstract

The invention discloses a shock-resistant ball valve. The shock-resistant ball valve comprises a first valve body, a rubber barrel and a second valve body. The rubber barrel is arranged between the first valve body and the second valve body. The first valve body and the second valve body are fixed through a bolt and are internally provided with polyurethane sleeves correspondingly. The polyurethane sleeves are arranged in a horn shape. A valve seat is arranged in the middles of the polyurethane sleeves. The valve seat and the polyurethane sleeves are integrally formed. A ball head is mounted in the valve seat. A valve rod is fixed to the top of the ball head. An end cover is arranged on the valve rod and fixedly connected with the first valve body and the second valve body. The valve rod penetrates through the middle of the valve deck. A first flange is welded to one end of the first valve body. A second flange is welded to one end of the second valve body. The compressive strength of the rubber barrel adopted by the shock-resistant ball valve is greater than 600 Mpa, damage is not prone to occurring, the anti-aging effect is achieved, and the abrasion resistance is good.

Description

technical field [0001] The invention relates to an impact-resistant ball valve. Background technique [0002] The existing ball valve standard GB / T21465-2008 "Valve Glossary" is defined as a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. According to the driving mode, the ball valve is divided into: pneumatic ball valve, electric ...
