A blowout-proof and disassembly-proof pressure gauge valve

Abstract

The invention discloses a blowout-proof and disassembly-proof pressure gauge valve, in which a connecting head is embedded and connected on the surface of a pipeline, and a sealing ring is fixed on the inner wall near the bottom of the connecting head, and a liquid passage hole is opened on the surface of the sealing ring , the inside of the connector is plugged with a pressure gauge body, and the surface of the pressure gauge body is fixed with a mounting ring. Through the cooperation of the above-mentioned structures, the present invention realizes the setting of the anti-theft box, avoids accidental rotation of the worm or intentional theft of the pressure gauge head, and achieves a certain purpose of preventing disassembly. At the same time, the pressing and fixing of the swing clamping assembly is released, so that the swing clamping assembly can swing, thereby releasing the clamping and fixing of the pressure gauge head, and it is convenient to remove the pressure gauge head, so that the pressure gauge head is removed At the same time, the connection head is blocked, preventing the liquid inside the pipeline from spraying out from the connection head, and improving the operation safety and operation efficiency.

Description

technical field [0001] The invention relates to the technical field of petrochemical equipment, in particular to a blowout-proof and disassembly-proof pressure gauge valve. Background technique [0002] The pressure gauge valve is installed on the transmission pipeline in the petroleum or chemical field to connect the pressure gauge with the pipeline through the valve body, so as to display the pressure of the gas in the pipeline. In order to measure the gas or liquid pressure in the pipeline, the pressure gauge valve is usually installed between the pipeline and the pressure gauge to form a connected cavity, that is, the gas or liquid in the pipeline can enter the pressure gauge through the connected cavity. within the measurement range. For petrochemical sites, sometimes pipelines will be laid in unguarded field areas. Due to unattended, the pressure gauge is easily stolen and lost, or the gas or liquid in the pipeline leaks due to damage to the pressure gauge, resulting ...

AI Technical Summary

Problems solved by technology

For petrochemical sites, sometimes pipelines are laid in unguarded field areas. Due to unguarded, the pressure gauge is easily stolen and lost, or the gas or liquid in the pipeline is leaked due to the damage of the pressure gauge, resulting in energy waste and environmental pollution. and potentially dangerous

[0003] Due to the simple structure of the existing pressure gauge valve, the disassembly process is relatively simple, and generally does not have the anti-theft function. Due to the leakage of liquid in the pipeline, there is a certain potential safety hazard, which brings inconvenience to the use, so it needs to be improved
