Description

Technical Field

[0001] This utility model relates to the field of safety valve technology, and in particular to a self-sealing pulse safety valve. Background Technology

[0002] Safety valves are important devices used to prevent the pressure of the medium in equipment or pipelines from exceeding the specified value. They automatically open to discharge the medium and ensure the safe operation of the system. They are widely used in chemical, power, water conservancy and other industrial fields, and their reliability is directly related to the safety and stability of the production system.

[0003] In the prior art, such as the Chinese patent CN219796326U entitled "A Safety Valve," a safety valve body is included. A connecting pipe is provided on the safety valve body, and a support seat is fixedly welded to the connecting pipe. A threaded rod is rotatably connected to the support seat, and a moving block is threadedly connected to the threaded rod. An adjusting seat is fixedly welded to the bottom side of the moving block, and two L-shaped connecting rods are movably arranged on the adjusting seat. Each of the two L-shaped connecting rods has an arc-shaped clamping plate fixedly welded to it. This invention, by rotating the double-ended screw, allows two sliders to move towards or away from each other within the groove, thereby driving the two arc-shaped clamping plates to move towards or away from each other, achieving clamping and fixing of pipes of different diameters. By rotating the threaded rod in the forward direction, the adjusting seat moves, and the adjusting seat, through the L-shaped connecting rods and the two arc-shaped clamping plates, tightly fits the pipe to the connecting pipe, thus achieving the effect of easily connecting various pipes of different diameters.

[0004] Although this type of safety valve facilitates the connection of various pipe diameters, its arc-shaped clamping plate and L-shaped connecting rod are fixedly welded together, making it impossible to replace with different pipe shapes (such as square, rectangular, and other non-circular pipes), thus limiting its applicability. Furthermore, the lack of an effective limiting structure for the threaded rod and double-ended screw means that after prolonged use, under the influence of pipe vibration or medium pressure fluctuations, the screw is prone to loosening, leading to gaps in the connection between the pipe and the connecting pipe, affecting the normal operation of the safety valve. Therefore, improvements are needed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where the clamping plate cannot be replaced according to the shape of the pipe (such as square, rectangular and other non-circular pipes), the scope of application is limited, and there is a lack of effective limiting structure for threaded rods and double-ended screws. Therefore, a self-sealing pulse safety valve is proposed.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a self-sealing pulse safety valve, comprising a safety valve body, a connecting pipe provided on the side of the safety valve body, an L-shaped seat fixedly mounted on the surface of the connecting pipe, a moving block slidably connected inside the L-shaped seat, an adjusting seat fixedly mounted on the lower surface of the moving block, a clamping arm provided on the lower surface of the adjusting seat, an arc-shaped clamping plate provided on the side of the clamping arm, a limiting mechanism provided on the surfaces of the L-shaped seat and the adjusting seat, a reinforcing rib fixedly mounted between the moving block and the adjusting seat, and a threaded rod rotatably connected inside the L-shaped seat.

The side of the clamping arm has a slot, and a fixing bolt is threadedly connected to the side of the clamping arm. The side of the insert block is provided with a magnet, and the inner wall of the slot is provided with a magnet.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a detachable connection structure of insert and slot is set between the adjusting seat and the clamping arm, and magnet one and magnet two are respectively set in the insert and slot. With the help of fixing bolts for secondary locking, the arc-shaped clamping plate can be quickly replaced, which is convenient for changing the appropriate clamping plate according to different pipe shapes (such as round, square, and rectangular), thus expanding the application range of the safety valve. In addition, a high-temperature resistant silicone pad is set on the side of the arc-shaped clamping plate to enhance the sealing performance between the clamping surface and the pipe. At the same time, the limiting rod of the limiting mechanism is inserted into the limiting holes of the first and second rotating heads.

The limiting mechanism 8 includes a mounting plate 801, a limiting plate 802 is slidably connected inside the mounting plate 801, a limiting rod 803 is fixedly installed on the side of the limiting plate 802, limiting holes 804 are opened on the sides of the rotating head 12 and the rotating head 2 16, a sliding rod 805 is fixedly installed inside the mounting plate 801, a tension spring 806 is sleeved on the surface of the sliding rod 805, the threaded rod 10 is threadedly connected to the moving block 4, the guide rod 11 is slidably connected to the moving block 4, and the lower surface of the connecting block 13 is connected to the clamp. The upper surface of the holding arm 6 is fixedly connected, the bidirectional lead screw 14 is threadedly connected to the connecting block 13, the guide rod 15 is slidably connected to the connecting block 13, the insert block 18 is slidably connected to the slot 19, the fixing bolt 20 is threadedly connected to the insert block 18, the magnet 1 21 and the magnet 2 22 attract each other, the limiting rod 803 is slidably connected to the limiting hole 804, the limiting plate 802 is slidably connected to the slide rod 805, one end of the tension spring 806 is fixedly connected to the side of the limiting plate 802, and the other end of the tension spring 806 is fixedly connected to the inner side of the mounting plate 801.

[0027] In this embodiment, a detachable connection structure of insert block 18 and slot 19 is provided between the adjusting seat 5 and the clamping arm 6. Magnet 1 21 and magnet 22 are respectively provided in insert block 18 and slot 19, and secondary locking is performed with fixing bolt 20. This allows the arc-shaped clamping plate 7 to be quickly replaced, making it convenient to replace the appropriate clamping plate according to different pipe shapes (such as round, square, and rectangular), thus expanding the application range of the safety valve. In addition, a high-temperature resistant silicone pad 17 is provided on the side of the arc-shaped clamping plate 7 to enhance the sealing performance between the clamping surface and the pipe. At the same time, the limiting rod 803 of the limiting mechanism 8 is inserted into the limiting hole 804 of the rotating head 1 12 and the rotating head 2 16. Under the action of the tension spring 806, the limiting rod 803 is kept fixed to prevent the rotating head from rotating and causing the clamping to loosen, thereby improving the stability of the overall structure.

[0028] Example 2: As Figures 1-5 As shown, a sealing groove 23 is provided on the end face of the connecting pipe 2, and a sealing gasket 24 is embedded inside the sealing groove 23. The sealing groove 23 and the sealing gasket 24 are circular in shape, and two sets of sealing groove 23 and sealing gasket 24 are provided.

[0029] In this embodiment, by setting two sets of circular sealing grooves 23 at the end of the connecting pipe 2 and fitting sealing gaskets 24, a double sealing structure is formed.

[0030] The working principle of this embodiment is as follows: First, select a suitable arc-shaped clamp 7 according to the pipe shape. Slide the insert 18 on the side of the arc-shaped clamp 7 into the slot 19 on the side of the clamping arm 6. The magnet 21 on the insert 18 and the magnet 22 in the slot 19 attract each other for initial fixation. Then, rotate the fixing bolt 20 on the side of the clamping arm 6 to make the fixing bolt 20 threadedly connected to the insert 18, completing the installation of the arc-shaped clamp 7. Next, pull the limiting plate 802 in the mounting plate 801 of the limiting mechanism 8. The limiting plate 802 slides along the slide rod 805 and stretches the tension spring 806, causing the limiting rod 803 to disengage from the limiting holes 804 on the sides of the rotating head 12 and the rotating head 26. Then, rotate the rotating head 26 to drive the bidirectional lead screw 14 to rotate, causing the connecting block 13 to move along the guide rod. The sliding motion of the second 15 causes the clamping arm 6 to move, allowing the two arc-shaped clamping plates 7 to clamp the pipe. Then, the limiting plate 802 is released, and the tension spring 806 resets, causing the limiting rod 803 to be inserted into the limiting hole 804 of the second 16 of the rotating head and fixed. Then, the rotating head 12 is rotated, causing the threaded rod 10 to rotate. The moving block 4 slides along the guide rod 11, causing the adjusting seat 5 to move. The adjusting seat 5, through the clamping arm 6 and the arc-shaped clamping plates 7, moves the pipe closer to the connecting pipe 2 until the pipe is in contact with the end face of the connecting pipe 2. The sealing gasket 24 in the sealing groove 23 of the end face of the connecting pipe 2 is squeezed. Then, the limiting plate 802 is released, and the tension spring 806 resets, causing the limiting rod 803 to be inserted into the limiting hole 804 of the first 12 of the rotating head and fixed, preventing the rotating head from rotating due to vibration or medium pressure, thereby avoiding loosening of the clamp.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
