Technical Field
[0001] This utility model relates to the technical field of safety valve testing devices, specifically a safety valve testing device based on a quick-assembly structure. Background Technology
[0002] A safety valve is an automatic valve that automatically opens when the system pressure exceeds a specified value, discharging the medium outside the system to prevent explosions caused by excessive pressure. Safety valve performance testing mainly includes opening pressure testing, sealing performance testing, and reseating pressure testing. Opening pressure refers to the pressure at which the safety valve automatically opens when the specified pressure is reached. Sealing performance refers to ensuring the safety valve remains sealed when closed to prevent media leakage. Reseating pressure refers to the pressure at which the safety valve automatically closes after discharging the medium. Conventional safety valve testing involves sequentially setting up opening pressure testing equipment and sealing performance testing equipment, and then transporting and testing the safety valves sequentially using corresponding transport devices. This method makes it difficult to simultaneously test the opening pressure and sealing performance of safety valves, and to effectively classify products that fail different performance tests.

[0013] Compared with the prior art, this utility model provides a safety valve detection device based on a quick-installation structure, which has the following advantages:
[0014] 1. A safety valve testing device based on a quick-assembly structure, comprising a turntable on which safety valves are placed. As the turntable rotates, the safety valves sequentially pass through an opening pressure testing device to test their opening pressure performance. Valve valves that pass the test proceed to a sealing performance testing device, while those that fail are collected in a first waste bin. The sealing performance testing device then tests the sealing performance of the safety valves; valves that pass the test are collected in a collection bin, while those that fail are collected in a second waste bin. This solution addresses the limitations of conventional safety valve testing methods, which involve sequentially setting up opening pressure testing and sealing performance testing devices and transporting and testing safety valves sequentially using corresponding transport devices. These methods fail to simultaneously test the opening pressure and sealing performance of safety valves, and also hinder the classification of products that fail different performance tests.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a safety valve detection device based on a quick-installation structure.
[0025] Please see Figures 1-7A safety valve testing device based on a quick-assembly structure includes a testing platform 1, a turntable 2 on the testing platform 1, multiple safety valve bodies 3 on the turntable 2, an opening pressure testing device 4 and a sealing testing device 5 on the testing platform 1, a transport device 6 on one side of the opening pressure testing device 4 and the sealing testing device 5, and a first waste bin 7, a second waste bin 8 and a storage bin 9 at the bottom of the testing platform 1.
[0026] Both the pressure detection device 4 and the sealing detection device 5 include a detector 10, which is in conjunction with the safety valve body 3.
[0027] The sealing test device 5 also includes a sealing device 11, which seals one end of the safety valve body 3.
[0028] Specifically, the safety valve body 3 is placed on the turntable 2, and the turntable 2 drives the safety valve body 3 to rotate towards the opening pressure detection device 4. The detector 10 tests the opening pressure performance of the safety valve body 3. At this time, the safety valve body 3 is in the open state. When the detector 10 delivers the specified pressure to the safety valve body 3, if the safety valve body 3 can open automatically, the opening pressure performance test of the safety valve body 3 is qualified. The turntable 2 continues to rotate, so that the tested safety valve body 3 rotates to the side of the sealing performance detection device 5, and the detector 10 tests the sealing performance of the safety valve body 3. At the same time, the sealing device 11 seals the outlet end of the safety valve body 3, so that the safety valve body 3 is in the closed state. After the tester 10 delivers the specified pressure to the safety valve body 3, if the pressure sensor 104 does not change, the sealing performance of the safety valve body 3 is deemed qualified. This causes the turntable 2 to rotate again, storing the qualified safety valve body 3 into the storage bin 9. When the tester 10 detects that the opening pressure performance of the safety valve body 3 is unqualified, the transport device 6 grabs the unqualified safety valve and transports it to the first waste bin 7. When the tester 10 detects that the sealing performance of the safety valve body 3 is unqualified, the transport device 6 grabs the unqualified safety valve and transports it to the second waste bin 8. This process classifies and collects safety valve bodies 3 with unqualified opening pressure performance, unqualified sealing performance, and qualified safety valve bodies 3.
[0029] By setting up a turntable 2, the safety valve is placed on the turntable 2. As the turntable 2 rotates, the safety valve passes through the opening pressure testing device 4 in sequence to test its opening pressure performance. Those that pass the test enter the sealing performance testing device, while those that fail are collected in the first waste bin 7. The sealing performance testing device tests the sealing performance of the safety valve. Those that pass the test are collected in the collection bin 9, while those that fail are collected in the second waste bin 8. This solves the problem that conventional safety valve testing, which involves setting up opening pressure testing equipment and sealing performance testing equipment in sequence and transporting and testing the safety valves in sequence through the corresponding transportation device 6, is difficult to achieve the effect of simultaneously testing the opening pressure performance and sealing performance of the safety valve, as well as classifying products that fail different performance tests.
[0030] Specifically, a servo motor 12 is fixedly connected to the bottom of the testing table 1, and the turntable 2 is rotatably connected to the testing table 1 through a bearing. The output end of the servo motor 12 is fixedly connected to the bottom axis of the turntable 2, and multiple mounting sleeves 13 are fixedly connected to the top of the turntable 2. The safety valve body 3 is fitted inside the mounting sleeve 13.
[0031] The servo motor 12 drives the turntable 2 to rotate on the test platform 1, thereby driving the safety valve body 3 inside the mounting sleeve 13 to rotate, and thus the safety valve is tested by opening the pressure testing device 4 and the sealing performance testing device.
[0032] Specifically, the safety valve body 3 includes a valve body 31, an air inlet 32 located on the outer periphery of the valve body 31, and an air outlet 33 located on the top of the valve body 31. A limiting groove 34 is provided on the mounting sleeve 13, and the air inlet 32 is slidably disposed in the limiting groove 34.
[0033] The detector 10 includes a first cylinder 101, an air pump 102 fixedly mounted on the first cylinder 101, a detection nozzle 103 fixedly mounted on the air pump 102, and a pressure sensor 104. The output end of the detection nozzle 103 is matched with the air inlet 32.
[0034] The sealing device 11 includes a sealing gasket 111. A vertical plate 112 is fixedly installed on the test table 1. A horizontal plate 113 is fixedly connected to the top of one side of the vertical plate 112. A second cylinder 114 is fixedly connected to the horizontal plate 113. A movable plate 115 is provided at the bottom of the horizontal plate 113. A vertical rod 116 is fixedly connected to the horizontal plate 113. The movable plate 115 is sleeved on the vertical rod 116. One end of the piston rod at the output end of the second cylinder 114 is fixedly connected to the movable plate 115. A bearing seat 117 is fixedly connected to one side of the bottom of the movable plate 115. The sealing gasket 111 is fixedly installed on the bearing seat 117. The bottom of the sealing gasket 111 is in contact with the air outlet 33 of the valve body 31.
[0035] The turntable 2 drives the safety valve inside the mounting sleeve 13 to rotate. Through the cooperation between the upper limit groove 34 of the mounting sleeve 13 and the air inlet 32 on one side of the safety valve body 3, the safety valve body 3 is prevented from shifting position as the turntable 2 rotates, thus preventing the detection nozzle 103 on the detector 10 from communicating with the air inlet 32. The turntable 2 drives the safety valve body 3 to the position of the opening pressure detection device 4. The detector 10 tests the opening pressure performance of the safety valve body 3. At this time, the safety valve body 3 is in the open state, and the turntable 2 stops rotating. The first cylinder 10... 1. Move the air pump 102 and the test gun 103 to the air inlet 32 on one side of the safety valve body 3. When the tester 10 delivers the specified pressure to the safety valve body 3, if the safety valve body 3 can open automatically, the opening pressure performance test of the safety valve body 3 is qualified. At this time, the turntable 2 rotates again and drives the qualified safety valve body 3 to the position of the sealing test device 5. If the safety valve body 3 cannot open automatically, the opening pressure performance test of the safety valve body 3 is unqualified. The safety valve body 3 is grabbed and transported to the No. 1 waste bin 7 by the transport device 6.
[0036] After the safety valve body 3 rotates to the sealing detection device position, the second cylinder 114 drives the sealing gasket 111 to move downward, so that the sealing gasket 111 seals the air outlet 33 at the top of the safety valve body 3, so that the safety valve body 3 is in the closed state. Then, after the specified pressure is delivered to the air inlet 32 of the safety valve body 3 through the detection gun 103, if the value of the pressure sensor 104 does not change, the sealing performance of the safety valve body 3 is qualified, so that the turntable 2 rotates again and puts the qualified safety valve body 3 into the storage bin 9. If the value of the pressure sensor 104 changes, the sealing performance of the safety valve body 3 is unqualified, and the safety valve body 3 is picked up by the transport device 6 and transported to the second waste bin 8.
[0037] Specifically, the transport device 6 includes a pneumatic gripper 61, a gantry frame 62 fixedly connected to the inspection table 1, a guide rail 63 fixedly installed on the gantry frame 62, a slide cylinder 64 slidably mounted on the guide rail 63, a fixed plate 65 fixedly connected to the slide cylinder 64, a third cylinder 66 fixedly connected to one side of the fixed plate 65, a loading plate 67 provided at the bottom of the third cylinder 66, the output end of the third cylinder 66 fixedly connected to the loading plate 67, and the pneumatic gripper 61 fixedly mounted on the loading plate 67.
[0038] The testing platform 1 has two discharge ports 14, which are located at the bottom of the two transport devices 6 respectively. The first waste bin 7 and the second waste bin 8 are located directly below the two discharge ports 14 respectively.
[0039] When the pressure testing device 4 detects that the safety valve body 3 is unqualified, the slide cylinder 64 drives the fixing plate 65 and the pneumatic gripper 61 at the bottom of the fixing plate 65 to move towards the safety valve body 3. When the pneumatic gripper 61 is at the top of the safety valve body 3, the third cylinder 66 drives the loading plate 67 to move downward. The pneumatic gripper 61 fixes and grips the safety valve body 3. Then, the third cylinder 66 drives the safety valve body 3 to detach from the mounting sleeve 13, and the slide cylinder 64 drives the pneumatic gripper 61 holding the safety valve body 3 to move towards the discharge port 14 at the top of the first waste bin 7. When the safety valve body 3 is directly above the discharge port 14 at the top of the first waste bin 7, the pneumatic gripper 61 releases, allowing the safety valve body 3 to be stored in the first waste bin 7. Similarly, when the sealing performance testing device detects that the safety valve body 3 is unqualified, the transport device 6 transports the safety valve body 3 to the second waste bin 8.
[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
