Description

Technical Field

[0001] This utility model relates to the field of pressure testing equipment technology, and in particular to a pressure testing system. Background Technology

[0002] Pressure testing is a crucial step in ensuring that machinery and equipment can operate normally and reliably during operation. It is typically conducted after the equipment has been installed. Through pressure testing, the sealing performance, pressure resistance, and pressure release function of the machinery and equipment can be checked, ensuring that the equipment can cope with various pressure changes and guarantee safety during operation.

[0003] Chinese utility model patent CN200820027956.0 discloses a wellhead integrated pressure testing device, comprising a wellhead sealer, casing valve, wellhead four-way connector, casing hydraulic hose, power hydraulic hose, return hose, hydraulic motor, and working machine. The wellhead four-way connector is installed on the casing, the casing valve is installed on the side of the wellhead four-way connector, and the wellhead sealer is installed on the wellhead four-way connector. One end of the hydraulic hose is connected to the casing valve, and the other end is connected to the hydraulic motor. One end of the power hydraulic hose and the return hose are connected to the hydraulic motor, and the other end is connected to the working machine. The tubing is inside the casing, and the casing and tubing are separated by a packer to isolate pressure. This device allows for on-site pressure testing of the installed wellhead assembly, ensuring reliable operation, preventing leaks at the sealer and connections of the wellhead assembly, and ensuring that the well is under control during a blowout, preventing leakage at the wellhead and avoiding personal injury and property damage, thus demonstrating significant economic benefits.

This poses a significant safety hazard to the pressure testing operation. Firstly, the area where manual operation is performed is under the high-pressure coverage of the pneumatic pressure testing pump; if the pump malfunctions or leaks, it could easily cause personal injury to the workers.

[0029] A support pipe 5 is fixedly connected inside the diversion pipe 4. A pressure relief valve assembly 6 is installed on the upper surface of the support pipe 5. The pressure relief valve assembly 6 includes a pressure relief pipe 601, which is fixedly connected to the upper surface of the support pipe 5.

A motor 604 is fixedly connected to the outer wall of the bracket 603. The motor 604 is connected to a remote controller, which can remotely control the start and stop of the motor 604 to achieve automatic pressure relief, reduce manual operation, and improve safety.

[0030] Working Principle: During use, the outer ends of the two diversion pipes 4 are fixedly connected to the machine equipment requiring pressure testing. The pneumatic pressure testing pump 1, motor 304, and motor 604 are connected via a remote control device. The pneumatic pressure testing pump 1 and the corresponding motor 304 are controlled according to the actual pressure testing circuit. The pneumatic pressure testing pump 1 delivers gas into the main pipeline 2. Pressure gauge 7 monitors the gas pressure inside the main pipeline 2. Motor 304 rotates the sealing plate 305 90 degrees, opening it. Gas enters the corresponding inlet valve assembly 3 from the main pipeline 2 and then flows into the diversion pipes 4. Two pressure gauges 8 inside the diversion pipes 4 monitor the gas pressure in real time. When the test pressure matches the predetermined pressure, the sealing plate 305 needs to be quickly closed. The gas is then pneumatically controlled by the remote control device. Motor 304 drives sealing plate 305 to rotate 90 degrees and close, sealing the vent groove 306 to prevent gas from re-entering the diversion pipe 4. Simultaneously, the pneumatic pressure testing pump 1 is shut down. Pressure gauge 7 and two pressure gauges 8 monitor the pressure inside the main pipe 2 and diversion pipe 4. After the pressure test is completed, pressure relief is required. The remote control motor 604 starts, causing sealing plate 605 to rotate 90 degrees and open. Gas is discharged through the inside of diversion pipe 4 towards the support pipe 5, and then through pressure relief pipe 601, valve pipe 602, and pressure relief pipe 607 to the outside, thus achieving automatic pressure relief. This solves the problem of manually opening and closing valves for pressure testing or relief, ensuring timely valve operation of the pressure testing system and preventing accidents caused by manual valve operation, thereby improving safety.
