Description

Technical Field

[0001] This utility model relates to the field of pipe fitting technology, and in particular to a pipe reducer with a pressure gauge. Background Technology

[0002] In pipe connection systems, reducers are key components for transitioning between pipes of different diameters and are widely used in water supply and drainage, gas transmission, chemical industry, and HVAC.

[0003] Plug-in is a common connection method for pipe reducers to connect to external pipes. Plug-in reducers usually achieve sealing through rubber sealing rings. However, during the insertion of the reducer into the external pipe, the sealing ring is also subjected to friction from the contact with the external pipe, causing the sealing ring to tend to move in the opposite direction as the reducer is inserted. This leads to displacement of the sealing ring and thus sealing failure. To address this, we propose a pipe reducer with a pressure gauge that provides reliable sealing. Utility Model Content

Detailed Implementation

[0031] 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.

[0032] This utility model provides, for example Figures 1-3 The illustrated pipe reducer with pressure gauge includes a reducer body 101, a first sealing mechanism, a reinforcing mechanism, and a second sealing mechanism. A first connecting portion 301 is provided on one side of the reducer body 101, and a second connecting portion 201 is provided on the other side. A guide mechanism is provided on the outer wall of the first connecting portion 301. The first sealing mechanism is located on the outer wall of the first connecting portion 301. The reinforcing mechanism is located between the first sealing mechanism and the first connecting portion 301. The second sealing mechanism is located on the outer wall of the second connecting portion 201. The first connecting portion 301 is connected to an external pipe by insertion, and the second connecting portion 201 is connected to the external pipe by compression. The first sealing mechanism seals the first connecting portion 301 to the external pipe. Since the first connecting portion 301 is to be inserted into the external pipe, the reinforcing mechanism restricts the position of the first sealing mechanism on the outer wall of the first connecting portion 301, preventing displacement of the first sealing mechanism when the first connecting portion 301 is inserted into the external pipe, thus ensuring the stable functioning of the first sealing mechanism.

[0033] The first sealing mechanism includes a sealing rubber ring 302, which is sleeved on the outer wall of the first connecting part 301. A reinforcing mechanism is disposed on the inner wall of the first connecting part 301. A first friction mechanism is disposed on the inner wall of the sealing rubber ring 302. When the first connecting part 301 is inserted into the external pipe, the sealing rubber ring 302 will be located between the outer wall of the first connecting part 301 and the inner wall of the external pipe, thereby sealing the connection between the first connecting part 301 and the external pipe through the sealing rubber ring 302.

[0034] The reinforcing mechanism includes an annular groove 401 and a connecting rubber ring 402. The connecting rubber ring 402 is fixedly fitted onto the inner wall of the sealing rubber ring 302. A locking mechanism is provided on one side of the connecting rubber ring 402. The annular groove 401 is opened on the outer wall of the first connecting part 301. The connecting rubber ring 402 is inserted into the annular groove 401. When the first connecting part 301 is inserted into the external pipe, the sealing rubber ring 302 will be squeezed between the outer wall of the first connecting part 301 and the inner wall of the external pipe. The annular groove 401 limits the connection rubber ring 402, making it difficult for the sealing rubber ring 302 to shift, thereby allowing the sealing rubber ring 302 to stably perform a sealing function.

[0035] The locking mechanism includes an annular groove 501 and a locking rubber ring 502. A second friction mechanism is provided on the outer wall of the locking rubber ring 502. The annular groove 501 is formed on the inner wall of the annular recess 401, and the locking rubber ring 502 is inserted into the annular groove 501. When the first connecting part 301 is connected to an external pipe, the locking rubber ring 502 is first inserted into the annular groove 401 from its position. Then, as the first connecting part 301 is inserted into the external pipe, the sealing rubber ring 302 is also subjected to friction from the contact with the external pipe, causing the sealing rubber ring 302 to move along with the insertion of the first connecting part 301. A reverse movement tendency is generated, which is transmitted to the locking rubber ring 502 through the connecting rubber ring 402, so that the locking rubber ring 502 always has a tendency to move into the annular groove 501. At this time, the locking rubber ring 502 is limited by the annular groove 501 and the connecting rubber ring 402 is limited by the annular groove 401, so that the sealing rubber ring 302 cannot move on the outer wall of the first connecting part 301, thereby improving the stability of the sealing rubber ring 302. The sealing rubber ring 302, the connecting rubber ring 402 and the locking rubber ring 502 are integrated and can be produced by injection molding.

[0036] The first friction mechanism includes a first extrusion protrusion 601, which is distributed and fixedly connected to the inner wall of the sealing rubber ring 302. The outer wall of the first extrusion protrusion 601 is in contact with the outer wall of the first connecting part 301. The first extrusion protrusion 601 increases the friction between the inner wall of the sealing rubber ring 302 and the outer wall of the first connecting part 301. The second friction mechanism includes a second extrusion protrusion 701, which is distributed and fixedly connected to the outer wall of the locking rubber ring 502. The outer wall of the second extrusion protrusion 701 is in contact with the inner wall of the annular groove 501. The second extrusion protrusion 701 increases the friction between the outer wall of the locking rubber ring 502 and the inner wall of the annular groove 501, further increasing the stability of the sealing rubber ring 302 in use.

[0037] The guiding mechanism includes an arc-shaped chamfer 801, which is located on the side of the outer wall of the first connecting part 301. Since the outer diameter of the first connecting part 301 matches the inner diameter of the external pipe, when the first connecting part 301 is inserted into the external pipe, the arc-shaped chamfer 801 will be inserted into the external pipe first. Then, the inclined guidance of the arc-shaped chamfer 801 will allow the first connecting part 301 to be stably inserted into the external pipe.

[0038] The second sealing mechanism includes an annular protrusion 202, an annular groove 203, and an O-ring 204. The annular protrusion 202 is disposed on the outer wall of the second connecting part 201, and the annular groove 203 is formed on the inner wall of the second connecting part 201. The annular groove 203 and the annular protrusion 202 are positioned opposite each other. The O-ring 204 is clamped on the inner wall of the annular groove 203. The external pipe connected to the second connecting part 201 is directly inserted into the second connecting part 201. Then, the annular protrusion 202 is squeezed by a clamp, which deforms the second connecting part 201 and drives the O-ring 204 to tightly press against the outer wall of the external pipe inserted into the second connecting part 201, thereby completing the connection between the second connecting part 201 and the external pipe. At the same time, the O-ring 204 seals the external pipe and the second connecting part 201.

[0039] The connector body 101 has a mounting hole 902 at its top end. A pressure gauge body 901 is inserted into the inner wall of the mounting hole 902. The pressure inside the connector body 101 can be detected by setting the pressure gauge body 901.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
