Abstract

The invention discloses a steel cylinder filling installation structure of a control instrument, relates to the technical field of filling installation structures, and aims to solve the problems thatin the prior art, when a steel cylinder is filled, the pressure intensity of gas in the steel cylinder is too high, and backflow often occurs. A conveying inner cavity is formed in a conveying pipeline, a fixing block is installed in the conveying pipeline, the conveying pipeline is connected with the fixing block through a bolt, a vent hole is formed in the fixing block, a fixing rod frame is installed in the fixing block, and the fixing block is fixedly connected with the fixing rod frame through a bolt; and a compression spring is installed on one side of the fixing rod frame, the fixing rod frame is connected with the compression spring in a welded mode, a sealing block is installed on one side of the compression spring, the compression spring is connected with the sealing block in a welded mode, a soft plug is installed on one side of the sealing block, and the sealing block is fixedly connected with the soft plug through glue.

Description

technical field [0001] The invention relates to the technical field of filling and installation structures, in particular to a steel cylinder filling and installation structure for a control instrument. Background technique [0002] Control instrument, an instrument that automatically controls the controlled variable, compares the measurement signal with a given value, calculates the deviation signal according to a certain control law, and outputs the operation result with a specified signal. In chemical production, it is also called The controller or regulating instrument is a chemical instrument that automatically controls the controlled variable near the set value with a certain accuracy. It compares the measured value of the controlled variable to be controlled with the required set value to obtain the deviation According to a certain functional relationship (called the control law), the control effect occurs, and the control valve or other actuators are manipulated to c...
