Description

Totally enclosed pipe clamp valve

Technical Field

The utility model relates to a pipe clamp valve field especially relates to totally enclosed pipe clamp valve.

Background

Pinch valves (Pinch Valve), also known in China as tube Pinch valves, air bag valves, Pinch-off valves, etc. The casing is the most important part of any pinch valve, and is the core of the pinch valve, providing corrosion resistance, wear resistance and pressure bearing capability. The quality of the pinch valve depends on the quality of the casing. The sleeve is extruded by pneumatic, electric, manual or hydraulic drive modes to achieve the switching/adjusting effect. The rubber sleeve of a tubular valve serves as a core component, usually consisting of an inner layer, an outer layer and reinforcing fibres. The molding is carried out by a primary vulcanization/secondary vulcanization process. Several companies with a long history of pinch valves have their own features. The American red valve holds a plurality of advanced casing patents, Larox has a mining equipment manufacturing background for many years, AKO has a German industrial standard refinement style, and the like. The types of the sleeves of the pinch valve can be divided into: standard bushings, thickened bushings, high-voltage bushings, tapered bushings, etc. The classification by material is more, and is common: natural rubber, fluororubber, chloroprene rubber, hypalon, ethylene propylene diene monomer rubber, nitrile rubber, food grade rubber, chlorobutyl rubber, etc. are approximately twenty-three.

However, when the existing pipe clamp valve is specifically installed, because the position of each pipeline is not fixed, the pipe clamp valve is generally installed on a pipeline on one side firstly during installation, and then the pipeline on the other side is butted with the pipeline, so that the pipe clamp valve can only be installed smoothly during laying of the pipeline, and cannot be installed according to sections, because the length of the pipeline reserved in the later period is difficult to be butted with the pipe clamp valve smoothly, and then the pipe clamp valve needs to be cut again to align, and meanwhile, because the pipe clamp valve is generally installed with the pipeline of the corresponding type, the universality is poor. Thus, a totally enclosed pinch valve is proposed
