A simulated leak device for pipeline leak detection testing

Abstract

This utility model relates to a simulated leak detection device for pipeline leak testing, comprising a connecting pipeline and an adjustment assembly. The adjustment assembly includes an adjustment valve, a rotary handle, a pointer, and a dial. The adjustment valve is located inside the connecting pipeline, with one end of the valve stem extending through the outer wall of the connecting pipeline and connected to the connecting shaft of the rotary handle. The pointer is fixedly installed at the end of the rotary handle near the connecting shaft, and the dial is fixedly installed on the outer wall of the connecting pipeline. By setting the adjustment assembly at the connecting pipeline, the adjustment valve of this assembly is manually controlled by rotating the rotary handle. Rotating the handle causes the pointer to rotate on the dial, thereby precisely controlling the rotation angle of the adjustment valve inside the connecting pipeline. This controls the opening and closing angle of the adjustment valve within the connecting pipeline, and based on the size of the opening and closing angle, determines the minimum opening and closing angle that the detection subject can detect, thus determining the sensitivity of the detection subject in detecting pipeline leaks.

Description

Technical Field

[0001] This utility model relates to the technical field of pipeline testing, and in particular to a simulated leakage device for pipeline leakage detection testing. Background Technology

[0002] Existing pipeline leak detection systems can provide a device that can be installed at intervals on a pipeline to detect multiple leak points. The leak point detection method involves placing the detection body between the pipelines, with signal lines connected to the detection body. The signal lines are used to collect pipeline signals to detect the pressure of the liquid in the nearby pipelines and transmit the signal to the detection body. The detection body then sends the signal to the control room for real-time monitoring by the control room personnel.

[0003] Existing detection devices all require testing at a test site before installation. The current detection method generally involves directly creating a leak point on the outer wall of the pipeline to determine whether the detection device can work properly. However, the current detection device experiments cannot control the degree of pipeline leakage, nor can they determine the detection sensitivity of the detection device. Utility Model Content

[0010] The adjustment assembly includes an adjustment valve, a rotary handle, a pointer, and a dial;

[0011] The regulating valve is located inside the connecting pipe. One end of the valve stem of the regulating valve protrudes through the outer wall of the connecting pipe and is connected to the connecting shaft of the rotating handle. The pointer is fixedly installed at the end of the rotating handle near the connecting shaft, and the scale is fixedly installed on the outer wall of the connecting pipe.

[0012] Rotate the handle to rotate the pointer. The angle at which the pointer rotates on the dial is the opening angle of the regulating valve.

[0020] (III) Beneficial Effects

[0021] The beneficial effects of this utility model are:

[0022] This invention provides a simulated leak detection device for pipeline leak testing. An adjusting component is installed at the connecting pipeline. The adjusting valve of this component is manually controlled by rotating a handle. Rotating the handle causes a pointer to rotate on a dial, allowing precise control of the rotation angle of the adjusting valve within the connecting pipeline. This controls the opening and closing angle of the valve within the connecting pipeline, thereby determining the minimum opening and closing angle that the detection subject can detect, which is the sensitivity of the detection subject to pipeline leaks. This allows for pre-control of the leakage level in the pipeline and determination of whether the detection subject is malfunctioning. Furthermore, it improves the efficiency of the detection subject test. This simulation experiment method has a simple structure and is easy to operate. It solves the technical problems of existing detection subject experiments that cannot control the degree of pipeline leakage or determine the detection sensitivity of the detection subject.

[0029] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figures 1-4 As shown, a simulated leak detection device for pipeline leak testing includes a connecting pipe 1 connected to the pipeline body 100 and an adjusting assembly 2. The adjusting assembly 2 includes an adjusting valve 21, a rotating handle 22, a pointer 23, and a scale 24. The adjusting valve 21 is located inside the connecting pipe 1. One end of the valve stem 221 of the adjusting valve 21 protrudes from the outer wall of the connecting pipe 1 and is connected to the connecting shaft of the rotating handle 22. The pointer 23 is fixedly installed at the end of the rotating handle 22 near the connecting shaft, and the scale 24 is fixedly installed on the outer wall of the connecting pipe 1. Rotating the rotating handle 22 causes the pointer 23 to rotate, and the angle of rotation of the pointer 23 on the scale 24 is the opening angle of the adjusting valve 21.

[0031] It should also be noted that a detection body is installed inside the pipe body 100, which is used to detect whether the pipe is leaking. The pipe body 100 is connected to the test pipe 200, and both ends of the test pipe 200 are welded and sealed. That is, the gas leakage of the connecting pipe 1 is the leakage of the pipe. The opening and closing of the valve stem 221 in the connecting pipe 1 is controlled by adjusting the rotation handle 22 of the adjustment component 2 to control the amount of exhaust gas.

[0032] A simulated leak detection device for pipeline leak testing includes an adjusting component 2 installed at the connecting pipeline 1. The adjusting valve 21 of this component 2 is manually controlled by a rotating handle 22. Rotating the handle 22 causes a pointer 23 to rotate on a scale 24, precisely controlling the rotation angle of the adjusting valve 21 within the connecting pipeline 1. This controls the opening and closing angle of the valve 21 within the connecting pipeline 1, thereby determining the minimum opening and closing angle that the detection subject can detect, which represents the sensitivity of the detection subject to pipeline leaks. This allows for pre-control of the leakage level in the pipeline and the determination of whether the detection subject is malfunctioning. Furthermore, it improves the efficiency of the detection subject test. The simulation experiment method is simple in structure and easy to operate. It solves the technical problems of existing detection subject experiments that cannot control the degree of pipeline leakage or determine the detection sensitivity of the detection subject.

[0033] Furthermore, a mounting pipe 11 is welded vertically to the side wall of the connecting pipe 1. The mounting pipe 11 is fitted onto the protruding part of the valve stem 221 of the regulating valve 21. A mounting plate is welded to the outer end of the mounting pipe 11, and the valve stem 221 can rotate relative to the mounting plate (not shown in the figure). This arrangement facilitates the operation of the rotating handle 22 of the regulating assembly 2.

[0034] Furthermore, the dial 24 is welded to one end of the mounting tube 11 near the connecting pipe 1, so that there is a gap between the dial 24 and the pointer 23. This allows for better rotation of the pointer 23 and facilitates its operation.

[0035] Furthermore, it also includes an exhaust hose 3. The exhaust hose 3 is fitted onto the end of the connecting pipe 1, and the exhaust hose 3 is connected to the connecting pipe 1. The exhaust hose 3 and the connecting pipe 1 are detachably connected by a clamp. This facilitates the discharge of gas during the test and can effectively buffer the gas.

[0036] Furthermore, the dial 24 has a quarter-sector shape and multiple angle scale lines 25 are provided on the dial 24. Furthermore, the angle scale lines 25 are 0°, 15°, 30°, 45°, 60°, 75°, and 90° respectively. This allows for control of the leakage amount from multiple angles, thereby controlling the amount of leakage detected by the detection body.
