Description

Technical Field

[0001] This utility model relates to the field of safety valve testing technology, specifically to an intelligent pressure gauge safety valve testing device. Background Technology

[0002] A safety valve is a special valve whose opening and closing elements are normally closed under the action of external force. When the pressure of the medium in the equipment or pipeline rises above the specified value, it prevents the pressure of the medium in the pipeline or equipment from exceeding the specified value by discharging the medium to the outside of the system.

[0003] To ensure the safety of safety valves, an airtightness test must be performed first. Common airtightness testing equipment is relatively simple and inconvenient to accurately detect trace amounts of gas released during testing. Moreover, the connection between the safety valve and the testing equipment lacks airtightness testing, which affects the overall testing results.

[0004] There is an urgent need for an intelligent pressure gauge safety valve detection device to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide an intelligent pressure gauge safety valve detection device to solve the problem of poor detection effect mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent pressure gauge safety valve detection device, comprising a detection box, a connecting chamber arranged on the left side inside the detection box, a first connecting pipe installed at the bottom right side of the connecting chamber, a second connecting pipe installed at the top right side of the connecting chamber, a regulating valve and a connecting flange installed on both the first and second connecting pipes, two sets of detection rings arranged inside the connecting chamber, a gas detection sensor installed inside the detection rings, a placement chamber arranged at the top right side of the detection box, an air compressor installed inside the placement chamber, the output end of the air compressor connected to the second connecting pipe through a pipe, a first detection chamber and a second detection chamber respectively arranged at the bottom right side of the detection box, an electronic leak detector installed inside the first detection chamber, an exhaust pipe installed inside the second detection chamber, a water inlet pipe and a drain pipe respectively installed on the right side of the second detection chamber, and a controller installed at the front end of the detection box.

[0007] As a further technical solution of this utility model, the first connecting pipe is connected to the first detection chamber, and the first detection chamber is connected to the second detection chamber through an exhaust pipe.

[0008] As a further technical solution of this utility model, the second detection chamber is filled with soapy water, and the end of the exhaust pipe is inserted into the soapy water.

[0009] As a further technical solution of this utility model, positioning sleeves are fixedly connected to both sides of the detection ring, and positioning blocks are provided on the inner wall of the positioning sleeves. Limiting slides are installed on both sides of the connecting chamber, and the positioning sleeves are slidably connected to the outside of the limiting slides.

[0010] As a further technical solution of this utility model, the detection ring is connected to the controller via a wire, and the air compressor and the electronic leak detector are connected to the controller via wires.

[0011] As a further technical solution of this utility model, both the first connecting pipe and the second connecting pipe are corrugated telescopic pipes, and a viewing window is installed at the front end of the second detection chamber.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the intelligent pressure gauge safety valve detection device not only realizes the function of enhancing the detection effect and facilitating the detection of airtightness, but also realizes the function of facilitating connection and installation;

[0013] (1) By setting up an electronic leak detector, a first detection chamber, an exhaust pipe, a second detection chamber and a viewing window, the air compressor sends air into the safety valve. The electronic leak detector inside the first detection chamber can accurately detect whether there is a trace amount of gas. At the same time, once there is a leak, the gas will enter the second detection chamber through the exhaust pipe and enter the soap water. This structure improves the detection efficiency and accuracy through the dual detection structure. Moreover, the soap water inside the second detection chamber can also judge the discharge rate of the safety valve based on the rate of bubble generation. This structure realizes the function of flexible detection.

[0014] (2) By setting up a detection ring, a limiting slide, a gas detection sensor and a positioning slide, after the safety valve is connected to the first connecting pipe and the second connecting pipe, the two sets of detection rings are moved to the pipe connection point respectively. The detection ring is limited and fixed by the positioning block on the positioning slide. While detecting the air tightness of the safety valve, the gas detection sensor on the detection ring can detect whether there is a leak at the connection point. When a leak is detected, the gas detection sensor can transmit the information to the controller and display the alarm through the controller. This structure realizes the function of conveniently detecting the air tightness of the connection.

[0015] (3) By setting up a first connecting pipe, a second connecting pipe, a regulating valve and a connecting flange, when it is necessary to monitor the safety valve, the safety valve can be installed on the equipment first. The first connecting pipe and the second connecting pipe are both made of corrugated expansion pipes. Therefore, the connection position can be adjusted according to the size of the safety valve during installation. After adjustment, the connection can be fixed by using the connecting flange. The regulating valve on the first connecting pipe and the second connecting pipe can adjust the air intake according to the detection requirements. This structure realizes the function of easy connection and installation. Attached Figure Description

[0023] The first connecting pipe 2 is connected to the first detection chamber 9. The first detection chamber 9 is connected to the second detection chamber 11 through the exhaust pipe 10. The second detection chamber 11 is filled with soapy water. The end of the exhaust pipe 10 is inserted into the soapy water.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, the air compressor 7 supplies air into the safety valve. The electronic leak detector 8 inside the first detection chamber 9 can accurately detect whether there is a trace amount of gas. At the same time, once there is a leak, the gas will enter the second detection chamber 11 through the exhaust pipe 10 and then into the soapy water. This structure improves detection efficiency and accuracy through a dual detection structure. Moreover, the soapy water inside the second detection chamber 11 can also determine the discharge rate of the safety valve based on the rate of bubble generation.

[0025] The detection ring 3 is fixedly connected to both sides of the positioning sleeve 18, and the inner wall of the positioning sleeve 18 is provided with positioning blocks. The two sides of the connecting chamber 6 are installed with limiting slides 5. The positioning sleeve 18 is slidably connected to the outside of the limiting slides 5. The detection ring 3 is connected to the controller 15 through wires. The air compressor 7 and the electronic leak detector 8 are connected to the controller 15 through wires.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, after the safety valve is connected to the first connecting pipe 2 and the second connecting pipe 4, the two sets of detection rings 3 are moved to the pipe connection points respectively. The detection rings 3 are fixed by the positioning block on the positioning sleeve 18. While detecting the air tightness of the safety valve, the gas detection sensor 17 on the detection ring 3 can detect whether there is a leak at the connection point. When a leak is detected, the gas detection sensor 17 can transmit the information to the controller 15 and the controller 15 can display an alarm.

[0027] Both the first connecting pipe 2 and the second connecting pipe 4 are corrugated expansion pipes, and a viewing window 16 is installed at the front end of the second detection chamber 11.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the safety valve is installed on the equipment before testing. The first connecting pipe 2 and the second connecting pipe 4 are both made of corrugated expansion pipes. Therefore, the connection position can be adjusted according to the size of the safety valve during installation. After adjustment, the connection can be fixed by connecting flange 20. The regulating valve 19 on the first connecting pipe 2 and the second connecting pipe 4 can adjust the air intake according to the testing requirements.

[0029] Working Principle: In use, the safety valve to be tested is first installed on the equipment. During installation, the connection position can be adjusted according to the size of the safety valve. After adjustment, it is fixedly connected using the connecting flange 20. The air compressor 7 supplies air to the safety valve. The regulating valves 19 on the first connecting pipe 2 and the second connecting pipe 4 can adjust the air intake according to the testing requirements. The electronic leak detector 8 inside the first testing chamber 9 can accurately detect the presence of trace amounts of gas. Simultaneously, if there is a leak, the gas will enter the second testing chamber 11 through the exhaust pipe 10 and then into the soapy water. This structure improves detection efficiency through a dual detection mechanism. The test is efficient and accurate. Moreover, the soapy water inside the second detection chamber 11 can determine the discharge capacity of the safety valve based on the rate of bubble generation. After the safety valve is connected to the first connecting pipe 2 and the second connecting pipe 4, the two sets of detection rings 3 are moved to the pipe connection points respectively. The detection rings 3 are fixed by the positioning block on the positioning sleeve 18. While detecting the airtightness of the safety valve, the gas detection sensor 17 on the detection ring 3 can detect whether there is a leak at the connection point. When a leak is detected, the gas detection sensor 17 can transmit the information to the controller 15 and the controller 15 can display an alarm. This structure realizes the function of conveniently detecting the airtightness of the connection.
