Rubber valve capable of randomly adjusting air inflow

Abstract

The invention relates to a rubber valve capable of randomly adjusting air inflow. The rubber valve capable of randomly adjusting the air inflow is arranged in the circumferential direction of a main pipeline and comprises a valve body section and positioning sections, wherein the valve body section and the positioning sections are mutually and vertically connected; the positioning sections are arranged at the upper end part and the lower end part of the valve body section; a positioning device is arranged on the main pipeline to position the rubber valve; the positioning device is tightly matched with the valve positioning sections and is in clearance fit with the valve body section, and an air inlet pipeline is arranged and connected to an annular clearance between the positioning deviceand the valve body section. The rubber valve capable of randomly adjusting the air inflow realizes the deformation of the middle part in different degrees by utilizing the pressure difference of air so as to achieve the effect of adjusting the cross section area of a channel and realize the random adjustment of air flow. The valve is simple in structure, small in size and convenient to automatically control. In addition, the sealing of the contact interfaces of the upper end part and the lower end part is realized by the elasticity of the rubber, so that sealing measures are saved.

Description

technical field [0001] The invention relates to a rubber valve capable of arbitrarily adjusting the intake air volume, which mainly realizes arbitrary adjustment of the air intake volume by virtue of the elastic deformation of the rubber, and has a simple structure and is convenient for control and adjustment. Background technique [0002] At present, traditional valves mainly include metal or plastic ball valves, butterfly valves, gate valves, slide valves, etc. These valves are all mechanical valves used to control the flow of gas and liquid media. The adjustment of the flow depends on manual or electric operation, while the electric adjustment valve has a large size, complex structure and high price, and can only realize the opening or closing of the valve. , it is not easy to realize the arbitrary control of flow.
