Problems solved by technology

[0002] In the process of scientific experiments, gases or liquids are often used as reaction gases or liquids. In order to conduct accurate experiments, it is necessary to control the flow rate or speed of the gas or liquid medium passing into the reactor to meet different reactions. Experimental needs, some current flow adjustment mechanisms are too complicated and costly, and cannot meet the requirements of low-cost experiments

Abstract

The invention relates to a flow regulation device. The flow regulation device comprises a seat with a size-adjustable circulation channel. The seat is fixedly connected with a flow regulator through a screw. The flow regulator comprises a cylindrical body. A spring is installed in the cylindrical body through a bottom support seat with an upper boss, and an upper support seat with a lower boss. The upper support seat is in inner-threaded connection with the cylindrical body, and the position of the upper support seat in the cylindrical body can be adjusted axially. The upper end face of the upper support seat is provided with a regulation groove. The upper portion of the cylindrical body is in threaded connection with a protective safety cap. The end face of the bottom support seat is in threaded connection with a flow regulation control valve plate. Two flow blocking bodies are arranged in the seat. A medium circulation face capable of regulating flow is formed between the flow regulation control valve plate and the upper end faces of the flow blocking bodies and communicates with a medium inlet and a medium outlet which are formed in the two ends of the seat correspondingly. The flow regulation device is simple in structure, convenient to install and accurate in flow regulation control.

Description

technical field [0001] The invention belongs to the technical field of flow adjustment, and in particular relates to a flow adjustment device. Background technique [0002] In the process of scientific experiments, gases or liquids are often used as reaction gases or liquids. In order to conduct accurate experiments, it is necessary to control the flow rate or speed of the gas or liquid medium passing into the reactor to meet different reactions. Experimental needs, some current flow regulating mechanisms are too complicated and costly, and cannot meet the requirements of low-cost experiments. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide a flow regulating device with simple structure and convenient installation and use. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A flow regulating device, comprising a base body with an adjustab...
