AI Technical Summary

Technical Problem

Existing pneumatic clamp valves have long operating times, low sensitivity, and are not easy to control flow rate, resulting in a narrow range of applications.

Method used

A pneumatic clamp valve structure including a housing, an inner sleeve, a cylinder tube, and a moving rod is designed. The air pressure in the air intake box is controlled by an external air source, which pushes the piston and the moving rod to achieve synchronous movement of the extrusion rod. The external air source is connected by a three-way pipe to stabilize the air pressure and adjust the moving distance of the extrusion rod to control the flow rate.

Benefits of technology

It improves the working efficiency and stability of pneumatic clamp valves, enables rapid flow regulation, reduces energy consumption, and expands the application range.

Abstract

The utility model provides a pneumatic pipe clamp valve convenient for flow regulation, which comprises a shell and an inner sleeve, two ends of the shell are respectively provided with a first flange and a second flange, the shell is composed of an upper shell and a lower shell which are symmetrical, the upper shell and the lower shell are connected through a bolt, the upper shell and the lower shell are respectively and fixedly provided with a cylinder pipe, and the inner sleeve is provided with an air inlet and an air outlet. An air inlet box is fixedly arranged on the top of the air cylinder pipe in a communicating mode, a moving rod is arranged in the air cylinder pipe in a sliding mode, a piston is arranged on the top of the moving rod, the bottom of the moving rod penetrates through the air cylinder pipe and is located on the inner side of the shell, an extrusion rod is arranged at the bottom of the moving rod, and the extrusion rod abuts against the upper surface of the inner sleeve. And two ends of the inner sleeve are respectively connected with the first flange and the second flange through bolts and are connected in the shell. The flow velocity control device has the advantages of being sensitive to operate, convenient to control the flow velocity and the like.
