Description

Technical Field

[0001] This utility model relates to the technical field of stainless steel pipe fittings, specifically to an explosion-proof fitting for the inlet and outlet ends of stainless steel pipes. Background Technology

[0002] Stainless steel pipeline systems for transporting water, gas, oil, or other media are widely used in industries such as chemical, petroleum, pharmaceutical, and mining. These environments often contain flammable and explosive gases or dust, which places extremely high demands on the safety of the pipeline system. However, some existing high-pressure pipeline joints, although they have good sealing performance, are prone to leakage and spark risks at the pipeline connection. Utility Model Content

[0003] To overcome the shortcomings of existing technologies, an explosion-proof connector for the inlet and outlet of stainless steel pipes is provided to solve the problem that although some existing high-pressure pipe connectors have good sealing performance, they are prone to leakage and spark risks at the pipe connection.

[0004] To achieve the above objectives, an explosion-proof connector for the inlet and outlet of a stainless steel pipe is provided, comprising: an explosion-proof connector body, wherein one end of the explosion-proof connector body is provided with a tapered connector.

[0005] The explosion-proof connector body is inserted into the stainless steel pipe connector on the side of the stainless steel pipe body through a tapered connector. An anti-loosening outer rigid ring and an elastic deformation inner ring are provided at the distance between the tapered connector and the stainless steel pipe connector. The elastic deformation inner ring is pressed against the tapered end of the tapered connector. The anti-loosening outer rigid ring is fitted into the inner wall of the stainless steel pipe connector through the outer ring teeth. The side of the stainless steel pipe connector is screwed to the tapered connector through a clamping nut.

[0006] Furthermore, the other end of the explosion-proof connector body is provided with a columnar connector, and the outer cylindrical surface of the columnar connector is provided with external threads.

[0007] Furthermore, the outer ring end face of the tapered joint is provided with an external thread; and the anti-loosening outer rigid ring is sleeved on the side adjacent to the external thread of the tapered joint ring face.

[0008] Furthermore, a stainless steel pipe joint is welded to the front end of the stainless steel pipe body, and the inner side of the stainless steel pipe joint is tightly fitted with the conical joint through a sealing ring.

[0009] Furthermore, the inner side of the stainless steel pipe joint is inserted into the inner side of the tapered joint via an inner insertion tube.

[0010] Furthermore, a snap-fit ​​protrusion is provided on the inner side of the anti-loosening outer ring, and teeth are provided on the outer ring surface of the anti-loosening outer ring.

[0011] Furthermore, the anti-loosening outer rigid ring is engaged with the elastically deformable inner ring via a snap-fit ​​convex ring.

[0012] Furthermore, a clamping nut is welded and fixed to the side end of the stainless steel pipe joint.

[0013] The beneficial effects of this utility model are as follows: the explosion-proof connector for the inlet and outlet of the stainless steel pipe utilizes an anti-loosening outer rigid ring with teeth on its outer surface and an elastically deformable inner ring to form an anti-loosening component. The elastically deformable inner ring is clamped and pressed against the outer conical surface of the conical connector, causing the compressed and deformed elastically deformable ring to undergo radial deformation. This radially pushes the teeth of the anti-loosening outer rigid ring to embed deeply into the stainless steel pipe wall. At the same time, the pressure nut is tightened and screwed onto the outside of the conical connector, achieving mechanical self-locking of the stainless steel pipe connector end. This enhances the vibration and impact resistance of the explosion-proof connector, facilitates the prevention of loosening and displacement of the sealing ring at the connector end, avoids the possibility of sparks generated by loosening friction, and improves the protective effect of the explosion-proof connector.

[0019] 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.

[0020] Please refer to Figures 1 to 4 As shown, this utility model provides an explosion-proof connector for the inlet and outlet of a stainless steel pipe, comprising: an explosion-proof connector body 1, with a tapered connector 3 provided at one end of the explosion-proof connector body 1.

[0021] The explosion-proof connector body 1 is inserted into the stainless steel pipe connector 41 on the side of the stainless steel pipe body 4 via the tapered connector 3. An anti-loosening outer rigid ring 5 and an elastic deformation inner ring 51 are provided at the distance between the tapered connector 3 and the stainless steel pipe connector 41. The elastic deformation inner ring 51 is pressed and set on the tapered end of the tapered connector 3. The anti-loosening outer rigid ring 5 is fitted into the inner wall of the stainless steel pipe connector 41 through the outer ring teeth. The side of the stainless steel pipe connector 41 is screwed to the tapered connector 3 through the clamping nut 6.

[0022] First, the anti-loosening outer ring 5 and the elastic deformation inner ring 51 are fitted onto the surface of the tapered joint 3 on the explosion-proof joint body 1. Then, a stainless steel pipe joint 41 of the corresponding diameter is inserted into the tapered joint 3. The clamping nut 6 or the explosion-proof joint body 1 is rotated to tighten the clamping nut 6 into the tapered joint 3. At this point, the anti-loosening outer ring 5 and the elastic deformation inner ring 51 are pressed into the space between the tapered joint 3 and the stainless steel pipe joint 41. The elastic deformation inner ring 51 is compressed and deformed, pressing tightly against the tapered end of the tapered joint 3. This causes the compressed elastic deformation ring 51 to undergo radial deformation, pushing the teeth of the anti-loosening outer ring 5 into the wall of the stainless steel pipe joint 41. Finally, the connection to the equipment interface is screwed through the columnar joint 2, completing the connection of the explosion-proof joint. This achieves mechanical self-locking at the stainless steel pipe joint end, enhancing the explosion-proof joint's vibration and impact resistance, preventing loosening and displacement of the sealing ring at the joint end, avoiding the possibility of sparks generated by loosening and friction, and improving the protective effect of the explosion-proof joint.

[0023] In this embodiment, a cylindrical connector 2 is provided at the other end of the explosion-proof connector body 1, and the outer cylindrical surface of the cylindrical connector 2 is provided with external threads. The outer ring end face of the tapered connector 3 is provided with external threads; and the anti-loosening outer rigid ring 5 is sleeved on the side adjacent to the external threads on the ring surface of the tapered connector 3.

[0024] In a preferred embodiment, the cylindrical connector 2 is used to connect the explosion-proof connector body 1 to the equipment interface, enabling the equipment to control the flow of the medium transported within the stainless steel pipe body 4. The external thread of the tapered connector 3 facilitates quick and easy engagement with the clamping nut 6, improving the installation efficiency of the explosion-proof connector.

[0025] In this embodiment, a stainless steel pipe joint 41 is welded to the front end of the stainless steel pipe body 4. The inner side of the stainless steel pipe joint 41 is tightly fitted with the tapered joint 3 through a sealing ring 42. The inner side of the stainless steel pipe joint 41 is inserted into the tapered joint 3 through an inner insertion tube 43.

[0026] As a preferred embodiment, the sealing ring 42 inside the stainless steel pipe fitting 41 facilitates a tight fit with the tapered fitting 3, ensuring a tight seal at the joint connection. The sealing ring 42 is made of fluororubber (FKM) or polytetrafluoroethylene (PTFE) to withstand various chemical media. The inner insertion pipe 43 facilitates the introduction of the medium from the stainless steel pipe body 4 into the explosion-proof fitting body 1.

[0027] In this embodiment, a snap-fit ​​protrusion 52 is provided on the inner side of the anti-loosening outer ring 5, and the outer ring surface of the anti-loosening outer ring 5 is provided with teeth. The anti-loosening outer ring 5 is snapped into the elastically deformable inner ring 51 by the snap-fit ​​protrusion 52. A clamping nut 6 is welded and fixed to the side end of the stainless steel pipe joint 41.

[0028] As a preferred implementation, the anti-loosening outer rigid ring 5 and the elastic deformation inner ring 51 form a built-in anti-detachment structure. By screwing the outer clamping nut 6, the anti-loosening outer rigid ring 5 and the elastic deformation inner ring 51 are pressed at the distance between the tapered joint 3 and the stainless steel pipe joint 41. The elastic deformation inner ring 51 deforms under pressure and pushes away, embedding the teeth of the anti-loosening outer rigid ring 5 into the pipe wall of the stainless steel pipe joint 41, achieving mechanical self-locking, avoiding the possibility of sparks caused by loosening friction, and preventing the joint from loosening.

[0029] This utility model of an explosion-proof connector for the inlet and outlet of stainless steel pipes effectively solves the problem that some existing high-pressure pipe connectors, although having good sealing performance, are prone to leakage and spark risks at the pipe connection. It achieves mechanical self-locking at the end of the stainless steel pipe connector, enhances the vibration and impact resistance of the explosion-proof connector, facilitates the prevention of loosening and displacement of the sealing ring at the connector end, avoids the possibility of sparks generated by loosening and friction, and improves the protective effect of the explosion-proof connector. It is suitable for explosion-proof connectors for the inlet and outlet of stainless steel pipes.

[0030] 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.
