Description

Technical Field

[0001] This utility model relates to explosion-proof valve connectors, specifically to a non-magnetic explosion-proof valve quick-sealing connector. Background Technology

[0002] In industrial testing and related fields, the connection of explosion-proof valves is a crucial step. Traditional connection methods often use flange or threaded connections; however, these methods have several significant problems. During testing, due to the characteristics of the connection structure, tilting often occurs, directly leading to poor sealing and affecting the accuracy and reliability of the test.

[0003] Meanwhile, in a magnetic field environment, most traditional connecting components are made of metal, which is easily affected by magnetic fields, leading to magnetic adsorption. This magnetic adsorption not only interferes with the normal operation of the equipment, but more seriously, it may cause electrical sparks, posing serious safety hazards such as explosions to industrial production.

[0004] In addition, traditional connection methods are cumbersome to operate and require a lot of time and manpower. When various industrial tests are required, they will greatly reduce testing efficiency and increase operator fatigue.

[0005] To address the aforementioned issues, meet the demands of industrial testing, reduce operator fatigue, and improve testing efficiency, this invention proposes a non-magnetic explosion-proof valve quick-sealing connector. Utility Model Content

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1: The specific structure of this utility model is as follows:

[0046] Please refer to the appendix. Figure 1-7 The present invention relates to a non-magnetic explosion-proof valve quick-sealing connector, comprising:

[0047] The shell has a through cavity that extends through both ends. The through cavity is a stepped chamber, and the wide end of the shell is equipped with a hook structure.

[0048] A central rod 4, the first end of which passes through the narrow end of the stepped chamber, and the second end of which extends into the wide cavity of the stepped chamber;

[0049] The suction cup assembly is fixed to the second end of the central rod 4, with its suction surface facing outwards.

[0050] A sealing assembly is disposed in the stepped chamber, sleeved on the central rod 4 and movable in the stepped chamber. The sealing assembly has a self-resetting structure and is limited by the suction cup assembly.

[0051] A handle assembly is rotatably connected to the first end of the center rod 4. The end face of the handle assembly abuts against the end face of the housing. The center rod 4 can be moved axially by rotating the handle assembly.

[0052] The shell includes a front cover 10 and a rear cover 3 connected together, and a first sealing structure is provided at the connection between the front cover 10 and the rear cover 3.

[0053] A second sealing structure is formed between the narrow end and the central rod 4.

[0054] The second end of the central rod 4 is provided with two protruding rings, and an annular groove is formed between the two protruding rings;

[0055] The suction cup assembly includes:

[0056] Suction cup 14, the inner end of which is fastened to the annular groove;

[0057] The suction cup housing 9 is a cylindrical structure, with one end sleeved on the central rod 4, and its cylindrical cavity sleeved on the outside of the inner end of the suction cup 14.

[0058] The sealing assembly includes a piston 8, a first spring 18, and a second spring 17;

[0059] The piston 8 is sleeved on the central rod 4. It is a circular convex structure with a circular stepped cavity inside.

[0060] The first spring 8 is sleeved on the central rod 4, and its two ends respectively abut against the suction cup outer shell 9 and the step of the stepped cavity;

[0061] The second spring 17 is a return spring, which is sleeved on the central rod 4. The first end of the second spring 17 abuts against the narrow end annular surface of the stepped chamber, and the second end is sleeved on the protrusion of the piston 8 and abuts against the outer annular surface of the piston 8.

[0062] A third sealing structure is provided between the piston 8 and the center rod 4.

[0063] The piston 8 has a main sealing ring 15 fixed at its outward-facing end.

[0064] The handle assembly includes a handle, a perforated pin 2, and a key ring 16. The handle is rotatably connected to the first end of the center rod 4 via the perforated pin 2. The key ring 16 connects to the rod portion of the perforated pin 2 to limit its movement. The handle includes a handle rod 7 and a handle head 6, which are connected. The handle head 6 has a U-shaped portion that connects to the perforated pin 2.

[0065] The hook structure includes:

[0066] Multiple notches are provided on the wide end of the shell, and at least two arc-shaped pillars are formed between the notches;

[0067] Multiple curved panels 5 are installed one-to-one on the end face of each curved column, and the inner curved end of the curved panel 5 extends inward to form a hook protruding from the end face of the curved column. Figure 3 In the middle, there are two arc panels 5, and the two arc panels 3 hook onto the annular groove of the non-magnetic explosion-proof valve sample 100.

[0068] Example 2:

[0069] The following is the working principle of the non-magnetic explosion-proof valve quick-sealing connector of this utility model:

[0070] like Figure 1-7 As shown, the installation and removal process of the non-magnetic explosion-proof valve sample 100 is as follows: Figure 7 As shown, when the handle rod 7 is pressed, the second spring 17 in the piston assembly and suction cup assembly will be compressed and moved upward by the pressure of the handle assembly. At this time, the piston, suction cup assembly, hook, and main body front cover 10 form a certain positional difference, which can just align the non-magnetic explosion-proof valve sample 100 with the hook and put it into the quick connector.

[0071] The non-magnetic explosion-proof valve sample 100 is in the loose state and can be removed at will.

[0072] Return the handle assembly to its original position (e.g.) Figure 6 As shown, the second spring 17 will open with the release pressure of the handle, and the main sealing ring 15 will fit tightly against the non-magnetic explosion-proof valve sample 100 below. At the same time, the suction cup 14 will press down on the end cap of the non-magnetic explosion-proof valve sample 100. Press the handle rod 7 towards the side of the handle head 6 that is closer to the cylindrical pin hole with holes in the handle head. At this time, the suction cup assembly will be lifted together with the center rod 4 as the handle is pressed down.

[0073] At this time, an air pressure difference will be formed inside the suction cup 14, which will firmly hold the end cap of the non-magnetic explosion-proof valve sample 100, thereby pulling up the end cap of the non-magnetic explosion-proof valve sample 100.

[0074] The piston 8 has a fluid orifice. Gas is filled into the fluid orifice and enters the end cap of the non-magnetic explosion-proof valve sample 100 to complete the test.

[0075] Return handle assembly (such as) Figure 6 As shown, at this time, the suction cup 14 automatically balances with the atmospheric pressure, avoiding extreme pulling of the suction cup 14 and extending its service life. The suction cup 14 is made of silicone material, which does not damage the non-magnetic explosion-proof valve sample 100 during testing. Press the handle rod 7 towards the side of the handle head 6 that is farther from the cylindrical pin hole with holes in the handle head to release the non-magnetic explosion-proof valve sample 100.

[0076] In summary, the connector of this utility model has a good sealing effect: by setting up a first sealing structure, a second sealing structure, a third sealing structure and a main sealing ring, multiple sealing structures can effectively prevent media leakage, ensure the sealing performance of the connection, and improve the accuracy of testing and other work.

[0077] The connector of this utility model has the following non-magnetic characteristics: the related components are made of non-magnetic materials, which can adapt to the magnetic field environment and avoid the safety hazards caused by the magnetic adsorption phenomenon of traditional metal connecting components in the magnetic field, thereby improving the safety of equipment operation.

[0078] This new connector is easy to operate: the axial movement of the center rod can be achieved by rotating the handle assembly, thereby completing the connection and sealing action. The operation process is simple and quick, reducing operator fatigue and improving work efficiency.

[0079] The connector of this utility model has a self-resetting function: the sealing component is equipped with a self-resetting structure, which can reset in time during operation to ensure the continuity and stability of the sealing effect.

[0080] The connector of this utility model has a stable connection: it is connected and fixed to external components through a hook structure, which is stable and reliable, and also facilitates disassembly and installation.
