Naked pipe clamp valve

Abstract

The invention provides an exposed pipe clamp valve which comprises a rubber pipe, the two ends of the rubber pipe are sleeved with flange frames, a pipeline frame is arranged between the two flange frames, and the pipeline frame is connected with the flange frames. The flange frame comprises an upper annular frame arranged at the top end of the outer portion of the rubber pipe in a sleeving mode and a lower annular frame arranged at the bottom end of the upper annular frame, a first connecting rod is connected between the upper annular frame and the pipeline frame, and a second connecting rod is connected between the lower annular frame and the pipeline frame. The pipeline frame comprises an upper supporting frame hinged to the first connecting rod, a lower supporting frame arranged at the bottom end of the upper supporting frame and a screw rod sequentially penetrating through the two ends of the upper supporting frame and the two ends of the lower supporting frame from top to bottom. According to the pipe clamp valve, a flange edge of a rubber pipe can be pressed tightly in the mounting process while a worker can disassemble the pipe clamp valve conveniently, and therefore the stability and the sealing performance of the pipe clamp valve are improved.

Description

technical field [0001] The invention mainly relates to the technical field of pipe pinch valves, in particular to a bare-open pipe pinch valve. Background technique [0002] Pinch valves are also known as pinch valves, pressure pipe valves, airbag valves, and pinch off valves in China. Use pneumatic, electric, manual or hydraulic driving methods to squeeze the casing to achieve the switch / regulation function. [0003] According to a naked pipe pinch valve provided by the patent literature with the application number CN201420038371.4, it can be known that the pipe pinch valve includes a frame body, a rubber hose and a gate clamp mechanism. And the screw, one end of the screw barrel is set on the frame body through the bearing and connected with the driving device, the inner wall of the other end of the screw barrel is threaded with one end of the screw, the other end of the screw is connected with the gate rod I, and the thread on the screw barrel is fitted with a connecting...

AI Technical Summary

Problems solved by technology

[0004] The main parts of the above-mentioned pinch valves are all exposed outside, which is convenient for workers to observe the working conditions of the pinch valves. However, the above-mentioned pinch valves still have defects. It is more troublesome, and it is difficult to adjust the support effect of the frame body on the rubber hose, thus affecting the support force of the frame body to the rubber hose
