Description

Technical Field

[0001] This utility model relates to the field of pipeline connection sealing technology, specifically a mechanical seal. Background Technology

[0002] Mechanical seal piping systems are piping systems that use mechanical seals at pipe joints or equipment interfaces to prevent fluid leakage during fluid transmission. This ensures that the pipeline maintains good sealing performance even under high pressure, high temperature, or corrosive environments, avoiding environmental pollution and material loss. They are widely used in industries such as chemical, petroleum, pharmaceutical, and food processing.

[0003] The existing patent publication number CN217401990U discloses a self-sealing pipe connector, including a connector body. The connector body includes a main connector, a secondary connector, a first connecting sleeve, and a second connecting sleeve. A connecting inner sleeve is welded to one side of each of the first and second connecting sleeves, and a sealing layer is adhered to one side of the connecting inner sleeve. The insertion rod of this invention is installed inside the secondary connector, and the sealing sleeve is installed inside the main connector. The insertion rod can be inserted into the inside of the sealing sleeve, thereby strengthening the tightness between the main connector and the secondary connector. However, during the use of the self-sealing pipe connector, after the main connector and the secondary connector are inserted, since it only provides sealing protection at the connection through the sealing layer, leakage will occur at the pipe connection after the sealing layer wears down over a long period of time. Therefore, we propose a mechanical seal to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the prior art, this utility model provides a mechanical seal that solves the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A mechanical seal includes two pipes. One end of the left pipe is connected to and fixed with a left seal, and one end of the right pipe is connected to and fixed with a right seal adapted to the left seal. The left and right seals are connected and fixed by four bolts. A rubber ring is fixed to the inner wall of the left seal, and the inner surface of the rubber ring is tightly fitted with the right seal. An annular groove is formed on one side wall of both the left and right seals. The left sealing ring is slidably connected inside the left annular groove, and a right sealing ring adapted to the left sealing ring is fixed inside the right annular groove. The left and right sealing rings are tightly fitted. Springs are fixed in an annular array on one side wall of both the left and right sealing rings, and the other end of the springs is fixed inside the corresponding annular groove.

[0009] Furthermore, the left sealing ring consists of a metal ring one and a rubber retaining ring one, and the right sealing ring consists of a metal ring two and a rubber retaining ring two.

[0010] Furthermore, a guide ring for limiting the bolt screw is fixed on one side of the left seal, and four slots are opened on one side wall of the right seal, with arc-shaped clamping plates for limiting the bolt nut tightly inserted into the corresponding two slots.

[0011] Furthermore, each slot is equipped with a permanent magnet, which is attracted to the corresponding arc-shaped card plate.

[0012] Furthermore, a left protective ring is fixed to one side wall of the left seal, and a right protective ring is fixed to one side wall of the right seal to cooperate with the left protective ring, and the left protective ring and the right protective ring are tightly fitted together.

[0013] Furthermore, anti-slip rings are fixed to the surfaces of both the left and right sealing elements, and these anti-slip rings are made of plastic.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the present invention provides a mechanical seal with the following advantages:

[0016] This utility model, through the arrangement of a pipe, a left seal, a right seal, bolts, a rubber ring, an annular groove, a left sealing ring, a right sealing ring, and a spring, utilizes a mechanical seal. During the use of this seal, after the left and right seals are inserted, the rubber rings ensure a tight fit, providing primary sealing protection. Furthermore, under the action of the spring, the left and right sealing rings also fit tightly, providing secondary sealing protection. Therefore, even if the rubber rings wear out, the pipe will not leak. By incorporating a guide ring, a slot, and an arc-shaped retaining plate, the left and right seals, after being fixed by bolts, are prevented from loosening due to the cooperation of the guide ring and the arc-shaped retaining plate, thus avoiding leaks at the pipe connection caused by loose bolts.

[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] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an embodiment of this utility model discloses a mechanical seal comprising two pipes 1. One end of the left pipe 1 is connected to and fixed with a left seal 2, and one end of the right pipe 1 is connected to and fixed with a right seal 3 adapted to the left seal 2. Anti-slip rings 16 are fixed to the surfaces of both the left and right seals 2 and 3. The anti-slip rings 16 are made of plastic and increase the friction between the hand and the surfaces of the left and right seals 2 and 3, thus providing an anti-slip effect when inserting or separating them. The left and right seals 2 and 3 are connected and fixed by four bolts 4. A rubber ring 5 is fixed to the inner wall of the left seal 2, and the inner surface of the rubber ring 5 is tightly fitted to the right seal 3. An annular groove 6 is formed on one side wall of both the left and right seals 3. A left seal 7 is slidably connected inside the left annular groove 6, and a right seal 7 is fixed inside the right annular groove 6. A right sealing ring 8 is adapted to the left sealing ring 7. The left sealing ring 7 and the right sealing ring 8 fit tightly together. Springs 9 are fixed in a ring array on one side wall of both the left sealing ring 7 and the right sealing ring 8. The other end of the springs 9 is fixed inside the corresponding annular grooves 6. In the process of using this mechanical seal, the right sealing element 3 can be inserted into the left sealing element 2. At this time, the two pipes 1 can be sealed and connected through the left sealing element 2 and the right sealing element 3. Then, the two can be fixed by four bolts 4. When the two are inserted, they can fit tightly together under the action of the rubber ring 5, which can achieve the effect of primary sealing. When the two are inserted, the left sealing ring 7 and the right sealing ring 8 will fit tightly together. Since the springs 9 will be squeezed when they fit together, the springs 9 will fit even tighter under the restoring force of the compressed springs 9, which can achieve the effect of secondary sealing.

[0027] like Figure 3 As shown, in some embodiments, the left sealing ring 7 is composed of a metal ring 701 and a rubber retaining ring 702, and the right sealing ring 8 is composed of a metal ring 801 and a rubber retaining ring 802. In use, the metal rings 701 and 801 facilitate the fixing of the spring 9 to the left sealing ring 7 and the right sealing ring 8, while the rubber retaining rings 702 and 802 improve the sealing effect after the left sealing ring 7 and the right sealing ring 8 are fitted together.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, in some embodiments, a guide ring 10 for limiting the bolt of the bolt 4 is fixed on one side of the left seal 2, and four slots 11 are opened on one side wall of the right seal 3. Arc-shaped clamping plates 12 for limiting the nut of the bolt 4 are tightly inserted into two corresponding slots 11. Permanent magnets 13 are fixed inside each slot 11. The permanent magnets 13 attract the corresponding arc-shaped clamping plates 12. The permanent magnets 13 can further enhance the stability of the arc-shaped clamping plates 12 after they are inserted into the slots 11. In use, the fixed guide ring 10 on the left seal 2 can guide and limit the bolt head of the bolt 4. After the nut on the bolt 4 is tightened, the two arc-shaped clamping plates 12 can be inserted into the slots 11 to limit the nut of the bolt 4, thus preventing the bolt 4 from becoming loose and affecting the overall sealing effect of the mechanical seal.

[0029] like Figure 3 As shown, in some embodiments, a left protective ring 14 is fixed to one side wall of the left seal 2, and a right protective ring 15 is fixed to one side wall of the right seal 3 to cooperate with the left protective ring 14. The left protective ring 14 and the right protective ring 15 fit tightly together, and a protective shell can be formed between the left seal 2 and the right seal 3 by utilizing their cooperation, thereby achieving the protection of the left sealing ring 7 and the right sealing ring 8.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
