Fluorine-lined regulating valve with buffer structure and usage method

Abstract

The invention discloses a fluorine-lined regulating valve with a buffer structure, which includes a valve body, the valve body, a stable support connected to the bottom of the valve body, and a connecting groove arranged on the inside of the valve body. A fluid chamber is opened inside the groove, a support plate is connected to the top of the valve body, and a connection plate is connected to the top of the support plate, a buffer box is connected to the top of the connection plate, and a drive box is installed on the top of the buffer box. One side of the drive box is connected with a drive motor, and the inside of the drive box is provided with a cut-off rod, one end of the cut-off rod runs through the top of the valve body, and a docking seat is installed on one side of the cut-off rod near its end, so The inside of the valve body is equipped with two groups of deflectors that are oppositely arranged by one end. When the present invention is in use, the compression of the spring rod can be used to buffer the shut-off rod, so as to play a better protective role. At the same time, it has a better sealing effect after the shut-off rod is blocked, and the whole valve body has better stability after being placed.

Description

technical field [0001] The invention relates to the field of regulating valves, in particular to a fluorine-lined regulating valve with a buffer structure and a use method thereof. Background technique [0002] Control valve, also known as control valve, in the field of industrial automation process control, by receiving the control signal output by the adjustment control unit, with the help of power operation to change the final control element of process parameters such as medium flow, pressure, temperature, liquid level, etc., generally by the executive According to the characteristics of the stroke, the regulating valve can be divided into straight stroke and angular stroke. According to the power used by the actuator, it can be divided into three types: pneumatic regulating valve, electric regulating valve and hydraulic regulating valve. The fluorine-type regulating valve is fastened and lined with fluorine, which can effectively prevent the corrosion of the regulating ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a fluorine-lined regulating valve with a buffer structure and its use method. When the cut-off rod is easy to collide and wear its internal structure, it will affect the service life of the valve body; the existing fluorine-lined regulating valve cannot accurately position the cut-off rod, resulting in slight leakage of the cut-off rod when it cuts off the flow The existing fluorine-lined control valves have relatively general stability during use, and it is inconvenient to install and fix the valve body, which leads to problems such as shaking of the valve body during use
