Quick butt joint device for safety valve sealing performance detection

Abstract

The utility model relates to the technical field of safety valve sealing performance detection, and discloses a rapid butt joint device for safety valve sealing performance detection, which comprises a detection device fixedly connected with two flange joint seats. When a nut seat moves, a small rolling shaft rotates in a small range under the guiding action of an inclined sliding groove, at the moment, a rotating rolling shaft descends and rotates to a flange plate of a detected safety valve at the same time until the rotating rolling shaft tightly presses the flange plate, and at the moment, the safety valve can be detected. The safety valve can be rapidly and conveniently detected through the arranged butt joint assembly, so that the safety valve detection efficiency can be improved, and the problem that the safety valve detection efficiency is not high due to the fact that the butt joint sealing force can be guaranteed only by using bolts for connection and fixation in the butt joint aspect of safety valve joints in a traditional mode is solved.

Description

Technical Field

[0001] This utility model relates to the field of safety valve sealing performance testing technology, specifically a quick docking device for safety valve sealing performance testing. Background Technology

[0002] In industrial production, safety valves are critical safety devices, and their stability and reliability are essential for ensuring the safety of the entire production line. However, over long-term use, the sealing performance of safety valves may decline due to various reasons, affecting their normal operation. Therefore, regularly conducting sealing tests on safety valves is an important measure to ensure production safety.

[0003] Traditional safety valve sealing tests typically require removing the safety valve from the production line and then using bolts and other fasteners to connect and fix the valve's flange to the testing equipment's flange. While this method ensures a tight seal, the process is cumbersome and time-consuming, reducing the efficiency of safety valve testing. Therefore, a quick-connection device for safety valve sealing tests is needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a quick docking device for safety valve sealing performance testing. This solves the problem that traditional methods require bolts for connection and fixation of safety valve joints to ensure sealing strength, resulting in low testing efficiency.

[0009] The convex rotating sleeve in the docking assembly is rotatably connected to the outer surface of the flange joint seat, and the teeth are opened on the convex rotating sleeve. A worm gear sleeve is fixedly sleeved on the convex rotating sleeve.

[0010] A worm gear is fixedly sleeved on the outer surface of the output shaft of the servo motor. The worm gear meshes with the worm wheel sleeve. The servo motor is fixedly connected to the flange joint seat through a support frame.

[0011] Multiple fixing brackets are fixedly connected to the edge of the flange joint seat, and the multiple fixing brackets are evenly arranged in a circumferential array.

[0012] Preferably, the two helical gears are rotatably connected to the horizontal and vertical plates of the fixed frame, respectively, and the two helical gears are meshed together.

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, this utility model provides a quick docking device for testing the sealing performance of safety valves, which has the following advantages:

[0020] 1. This quick-connect device for safety valve sealing testing, when moved via the nut seat, causes a small roller to rotate slightly due to the guiding effect of the inclined slide groove. The rotating roller descends and rotates onto the flange of the safety valve being tested until it is firmly pressed against the flange. Testing of the safety valve can then begin. The connection assembly allows for quick and convenient testing of the safety valve, improving testing efficiency and avoiding the problem of low testing efficiency caused by the traditional method of using bolts for connection and fixing to ensure a tight seal.

[0021] 2. The quick-connect device for testing the sealing performance of this safety valve, through the self-locking property of the worm gear and worm wheel sleeve when they mesh, and the self-locking property between the screw and the nut seat, enables the rotating roller to have a stable clamping force. Even in the event of a sudden power failure, the rotating roller will not loosen its clamping grip, thus exhibiting strong stability. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-4 This utility model provides a new technical solution: a quick docking device for testing the sealing performance of a safety valve, including a testing device 1, on which two flange joint seats 2 are fixedly connected, and each flange joint seat 2 is provided with a docking component, which is used to quickly connect the flange heads when testing the sealing performance of the safety valve.

[0029] The docking assembly includes a convex rotating sleeve 3, teeth 4, a servo motor 6, a gear 8, a helical gear 9, an inclined slide 12, a screw 13, a nut seat 14, a rotating roller 15, and a small roller 16.

[0030] The convex rotating sleeve 3 in the docking assembly is rotatably connected to the outer surface of the flange joint seat 2, the teeth 4 are opened on the convex rotating sleeve 3, and the worm gear sleeve 5 is fixedly sleeved on the convex rotating sleeve 3;

[0031] A worm 7 is fixedly sleeved on the outer surface of the output shaft of the servo motor 6. The worm 7 is meshed with the worm wheel sleeve 5. The servo motor 6 is fixedly connected to the flange joint seat 2 through the support frame.

[0032] Multiple fixing brackets 10 are fixedly connected to the edge of the flange joint seat 2, and the multiple fixing brackets 10 are evenly arranged in a circumferential array.

[0033] Furthermore, the two helical gears 9 are rotatably connected to the horizontal and vertical plates of the fixed frame 10, respectively, and the two helical gears 9 are meshed together.

[0034] Furthermore, the shafts of both helical gears 9 rotate through the outer surface of the fixing frame 10, and the gear 8 is fixedly sleeved on the shaft of the lower helical gear 9.

[0035] Furthermore, gear 8 meshes with teeth 4, and screw 13 is fixedly sleeved on the shaft of helical gear 9 on the upper side.

[0036] Furthermore, the nut seat 14 is threaded onto the outer surface of the screw 13, and fixing blocks 11 are fixedly connected to the horizontal plates of the fixing bracket 10.

[0037] Furthermore, the inclined groove 12 is formed on the inner arc surface of the fixed block 11, and the small roller 16 is rotatably connected to the outer surface of the nut seat 14.

[0039] Furthermore, during use, the safety valve requiring sealing testing is placed on two flange connector seats 2, aligning the safety valve flange with the corresponding flange connector seat 2. Then, the servo motor 6 is started. When the output shaft of the servo motor 6 rotates, it drives the worm gear sleeve 5 to rotate via the worm 7.

At this time, the testing device 1 can start testing the safety valve. The docking assembly can enable the safety valve to be tested quickly and conveniently, which can improve the efficiency of safety valve testing and avoid the problem of low testing efficiency caused by the need to use bolts to connect and fix the safety valve joint in the traditional method to ensure the sealing force.

[0040] Furthermore, the self-locking property of the worm 7 and worm gear sleeve 5 when they mesh, as well as the self-locking property between the screw and the nut seat 14, enables the rotating roller 15 to have a stable clamping force. Even in the event of a sudden power outage, the rotating roller 15 will not loosen its clamping force, thus exhibiting strong stability.
