Description

Technical Field

[0001] This utility model relates to the field of joint sealing technology, specifically a Green plug assembly. Background Technology

[0002] A Green plug usually refers to a sealing component used in conjunction with a Green head, or it can refer to a pipe sealing component with a similar structure and function.

[0003] Traditional Green plug assemblies consist of three main components: a sealing cap, a sealing plug, and a sealing ring (e.g., Figure 1 As shown, the sealing ring is compressed by the movement of the sealing plug within the sealing cap's internal thread, causing the sealing ring to adhere tightly to the outside of the sealing element, thus achieving a sealing and isolation function. However, the deformation of the sealing ring occurs under the spiral compression of the sealing plug. In addition to bearing axial compression, the sealing ring also bears the rotational force of the sealing plug, which makes the sealing ring prone to twisting and deformation. When the sealing ring is twisted and deformed and adheres to the sealing element, it leads to instability of the sealing contact surface. When the sealing element is under high pressure, the sealing ring is prone to deforming again, thus affecting the sealing effect of the sealing ring. Utility Model Content

[0004] The purpose of this invention is to provide a Green plug assembly. By setting a compression retainer, when the sealing plug rotates and moves within the inner cavity of the sealing cap, the compression retainer first applies axial compression to the sealing ring. Then, as the sealing plug moves axially, the compression retainer applies pressure to the sealing ring from the outside to the inside, keeping the sealing ring in a relatively static state to deform, thus avoiding twisting and deformation. This solves the problem of poor sealing effect caused by the easy twisting and deformation of the sealing ring in traditional Green plugs, thereby addressing the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a green plug assembly, comprising:

[0006] Main structure;

[0007] The main structure includes a sealing cap, a sealing plug, and a sealing ring. The inner cavity of the sealing cap is also movably provided with a compression retainer. The sealing ring is placed inside the compression retainer, and the compression retainer is placed inside the sealing plug. One end of the sealing plug is movably installed in the inner cavity of the sealing cap.

[0008] Preferably, the compression retainer includes a ring, and four sets of inclined arc-shaped compression plates are fixed at the bottom of the ring, with the inner side of the arc-shaped compression plates fitting against the outer wall of the sealing ring.

[0009] Preferably, the outer side of the sealing plug is provided with threads, and the inner sidewall of the sealing cap is provided with grooves. The sealing plug and the sealing cap are connected by threads and grooves.

[0010] Preferably, a limiting groove is formed around the inner sidewall of the sealing cap, one end of the limiting groove extends upward and communicates with the top of the sealing cap, and a limiting block is fixed at one end of the outer side of the arc-shaped extrusion piece, the limiting block being slidably disposed in the limiting groove.

[0011] Preferably, the inner side of the arc-shaped extrusion piece is provided with a slot, the sealing ring is engaged in the slot, and a support ring is fixed at the bottom of the inner cavity of the sealing cap. One end of the support ring extends to the inner side of the arc-shaped extrusion piece and fits against one end of the sealing ring.

[0012] Preferably, the angle between the outer wall of the arc-shaped extrusion piece and the inner wall of the sealing cap is 3-5 degrees, the outer diameter of one end of the arc-shaped extrusion piece is the same as the outer diameter of the ring, and the outer diameter of the ring is the same as the inner diameter of the sealing plug.

[0013] Preferably, the inner wall of the sealing ring has multiple sets of grooves arranged in a ring, and the depth of the grooves is one-third of the thickness of the sealing ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model, by stably installing the compression retainer inside the sealing cap and connecting the sealing plug to the sealing cap via threads, not only applies pressure axially to the compression retainer, but also compresses the sealing ring through the compression retainer and the sealing cap. Simultaneously, when the sealing plug penetrates deep into the sealing cap, it compresses the arc-shaped compression piece, causing the arc-shaped compression piece to move inward and apply pressure to the sealing ring from the side. This ensures that the sealing ring is compressed and tightly fitted to the outside of the sealing element while in a static state, thus achieving a sealing effect. Since the retainer does not rotate relative to the sealing cap, it provides protection for the sealing ring.

[0016] 2. By setting the groove, when the sealing ring is squeezed and adhered to the sealing element, the air in the groove is squeezed and compressed, and is in a high-pressure state. The high-pressure gas in the groove can be used to seal the sealing element, further improving the sealing effect of the plug. Attached Figure Description

[0024] 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.

[0025] like Figures 2-6 As shown, this utility model provides a Green plug assembly, including a main structure, which includes a sealing cap 1, a sealing plug 2 and a sealing ring 3. The inner cavity of the sealing cap 1 is also movably provided with a compression retainer 4. The sealing ring 3 is placed inside the compression retainer 4. The compression retainer 4 is placed inside the sealing plug 2. One end of the sealing plug 2 is movably installed in the inner cavity of the sealing cap 1.

[0026] By stably installing the compression retainer 4 inside the sealing cap 1 and connecting the sealing plug 2 to the sealing cap 1 via threads, pressure can be applied not only axially to the compression retainer 4, but also to the sealing ring 3 through the compression retainer 4 and the sealing cap 1. Simultaneously, when the sealing plug 2 is inserted into the sealing cap 1, it compresses the arc-shaped compression piece 42, causing the arc-shaped compression piece 42 to move inward and apply pressure to the sealing ring 3 from the side. This ensures that the sealing ring 3 is compressed and tightly fitted to the outside of the seal in a static state, thus achieving a sealing effect. Since the retainer does not rotate relative to the sealing cap 1, it provides protection for the sealing ring 3.

[0027] like Figure 4-5As shown, the compression retainer 4 includes a ring 41, and four sets of inclined arc-shaped compression plates 42 are fixed at the bottom of the ring 41. The inner side of the arc-shaped compression plates 42 is in contact with the outer wall of the sealing ring 3. By limiting the structure of the compression retainer 4, the ring 41 applies pressure from the end of the sealing ring 3, while the arc-shaped compression plates 42 apply pressure to the sealing ring 3 from the side. Both are used to limit the elastic deformation space of the sealing ring 3 based on the deformation of the sealing ring 3, and fit inward with the sealing element to achieve the purpose of sealing.

[0028] like Figure 3-5 As shown, the outer side of the sealing plug 2 is provided with threads 5, and the inner side wall of the sealing cap 1 is provided with grooves 6. The sealing plug 2 and the sealing cap 1 are connected by threads 5 and grooves 6. The threads 5 and grooves 6 facilitate the connection between the sealing plug 2 and the sealing cap 1, thereby compressing the compression retainer 4 and deforming the sealing ring 3.

[0029] like Figure 4-5 As shown, a limiting groove 7 is provided around the inner sidewall of the sealing cap 1. One end of the limiting groove 7 extends upward and communicates with the top of the sealing cap 1. A limiting block 8 is fixed to one end of the outer side of the arc-shaped extrusion piece 42. The limiting block 8 is slidably disposed in the limiting groove 7. Through the cooperation of the limiting groove 7 and the limiting block 8, the extrusion retainer 4 is conveniently limited, and the extrusion retainer 4 is kept to move axially in the sealing cap 1. This prevents the sealing plug 2 from rotating inside the sealing cap 1 and causing the extrusion retainer 4 to rotate, which would cause the sealing ring 3 to twist and deform when the extrusion retainer 4 rotates, thus affecting the sealing effect.

[0030] like Figure 4 As shown, a slot 9 is provided on the inner side of the arc-shaped extrusion piece 42, and the sealing ring 3 is snapped into the slot 9. A support ring 10 is fixed at the bottom of the inner cavity of the sealing cap 1. One end of the support ring 10 extends to the inner side of the arc-shaped extrusion piece 42 and fits against one end of the sealing ring 3. The slot 9 is used to limit the sealing ring 3 by the extrusion retainer 4, and to stably install the sealing ring 3 inside the extrusion retainer 4.

[0031] like Figure 4-5 As shown:

[0032] The angle between the outer wall of the arc-shaped extrusion piece 42 and the inner wall of the sealing cap 1 is 3-5 degrees. The outer diameter of one end of the arc-shaped extrusion piece 42 is the same as the outer diameter of the ring 41, and the outer diameter of the ring 41 is the same as the inner diameter of the sealing plug 2. By setting the tilt angle of the arc-shaped clamp, it is ensured that after the sealing plug 2 rotates between the extrusion retainer 4 and the sealing cap 1, it can apply pressure to the arc-shaped extrusion piece 42, causing it to contract inward and compress the sealing ring 3, ensuring that the sealing ring 3 is in a compressed state.

[0033] In addition, such as Figure 6As shown:

[0034] Multiple sets of grooves 11 are circumferentially formed on the inner sidewall of the sealing ring 3. The depth of the grooves 11 is one-third of the thickness of the sealing ring 3. By setting the grooves 11, when the sealing ring 3 is squeezed and adhered to the sealing element, the air in the grooves 11 is squeezed and compressed, and is in a high-pressure state. The high-pressure gas in the grooves 11 can be used to seal the sealing element, further improving the sealing effect of the plug. At the same time, the depth of the grooves 11 is one-third of the thickness of the sealing ring 3, so as not to affect the integrity of the sealing ring 3 and avoid damage to the sealing ring 3.

[0035] In practical use, the sealing ring 3 is placed in the groove 9 inside the arc-shaped extrusion plate 42, and then the sealing cap 1 is put on the outside of the sealing joint. Next, the extrusion retainer 4 with the sealing ring 3 is put on the sealing joint, while the limiting block 8 slides in the limiting groove 7, allowing the extrusion retainer 4 to be inserted into the sealing cap 1. Then, the sealing plug 2 is inserted into the sealing cap 1. After rotating the sealing plug 2, with the cooperation of the thread 5 and the groove 6, the sealing plug 2 moves spirally inside the sealing cap 1. When the sealing plug 2 rotates inside the sealing cap 1... The inner wall of the sealing plug 2 slides along the outer wall of the ring 41. First, the sealing plug 2 squeezes the arc-shaped extrusion piece 42, causing the arc-shaped extrusion piece 42 to shrink inward. Then, the arc-shaped extrusion piece 42 squeezes the sealing ring 3. After the sealing plug 2 is inserted into the sealing cap 1, the sealing plug 2 squeezes the ring 41 again. With the cooperation of the support ring 10, the ring 41 and the support ring 10 apply pressure to the sealing ring 3 from both ends, causing the sealing ring 3 to shrink inward within the effective space and fit against the outside of the sealing joint, thus sealing the sealing joint in conjunction with the sealing plug 2.

[0036] 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.
