Description

Technical Field

[0001] The utility model relates to the technical field of forging joint equipment, in particular to a forging joint for pipe fittings. Background Art

[0002] Pipe joints are used for various applications of fluid-tightly connecting two pipe ends. They are mass-produced because, based on their uses in industrial fields, such as in shipbuilding or factories, many such pipe joints are assembled. Pipe joints must meet corresponding standards and strict mechanical requirements here.

[0003] Application No. 201880022599.5 discloses a pipe joint for connecting two pipe ends, which includes a clamping band having a longitudinal groove, an inner shell disposed therein, and a clamping mechanism for reducing the inner diameter of the clamping band. The clamping band is also designed as a flat single piece and has an outer band part and an inner band part, and the inner band part is connected to the outer band part via at least one connecting device. In addition, a connecting assembly for fixing the inner shell in the clamping band is provided, and the connecting assembly includes a first connecting part and a second connecting part. The first connecting part extends into the second connecting part, and at least one connecting part of the connecting assembly is designed as at least one connecting device to connect at least one first outer band part of the clamping band to at least one first inner band part, and this pipe joint can be easily and quickly assembled during application under difficult conditions.

[0004] One defect existing in the above-mentioned document is as follows: when the pipeline slope is large and the water flow velocity in the pipeline is too fast, it is impossible to buffer the water flow when the flow velocity needs to be reduced and lower the flow velocity.

[0005] It can be seen from this that the existing forging joints for pipe fittings do not have the function of buffering and decelerating the water flow, and it is necessary to improve the existing deficiencies to provide a function that can buffer and decelerate the water flow.

[0006] The purpose of the utility model is to provide a forging joint for pipe fittings to solve the problems raised in the above background art.

[0007] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0008] The utility model is a forging joint for pipe fittings, including a flow resistance component.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figure 1 - Figure 4 As shown, the present invention is a forging joint for pipe fittings, including a flow-blocking component 1. The flow-blocking component 1 includes a flow-blocking housing 101. One end of the flow-blocking housing 101 is provided with a flow-blocking head 104. Four overflow holes 105 are evenly opened around the surface of the flow-blocking head 104. The surface of the flow-blocking housing 101 is provided with a second external thread 106. The flow-blocking housing 101 is connected with a sealing component 2 through the second external thread 106. A connecting component 3 is clamped inside the sealing component 2. The purpose of this setting is that when water flows in the pipeline and reaches the top of the flow-blocking housing 101, it is blocked, the kinetic energy of the water flow decreases, the speed decreases, and it fills the flow-blocking head 104. When the water volume in the flow-blocking head 104 reaches a certain fullness, the water flows out from the four overflow holes 105 provided on the surface of the flow-blocking head 104 and impacts the inner wall of the connecting housing 301, and the flow rate further decreases.

[0026] A limiting groove 103 is opened on the surface of the flow-blocking housing 101, and an elastic rubber ring 4 is clamped inside the limiting groove 103. The purpose of this setting is that the elastic rubber ring 4 is pressed into the limiting groove 103 opened on the surface of the flow-blocking housing 101, thereby improving the sealing performance at the joint interface of the joint.

[0027] The outer surface of one end of the flow-blocking housing 101 away from the flow-blocking head 104 is provided with a first external thread 102.

[0028] The sealing component 2 includes a sealing housing 201. The inner wall of the sealing housing 201 is provided with a first internal thread 202, and the outer surface of the sealing component 2 is provided with an anti-slip groove 203. The purpose of this setting is that the anti-slip groove 203 provided on the surface of the sealing housing 201 can effectively prevent slipping during installation.

[0029] The connecting component 3 includes a connecting housing 301. The inner wall at one end of the connecting housing 301 is provided with a second internal thread 302. The inner diameter of the connecting housing 301 is the same as the outer diameter of the end of the flow-blocking housing 101 provided with the first external thread 102. The purpose of such a setting is that when needed, multiple joints can be connected end to end to achieve multiple buffering of the water flow.

[0030] Around the other end of the connecting housing 301, there are convex blocks 303. The outer diameter of the convex blocks 303 is larger than the inner diameter of the opening of the sealing housing 201 near the connecting housing 301. The purpose of such a setting is to snap the connecting housing 301 inside the sealing housing 201.

[0031] During use, when the forged joint is being connected, first, the connecting housing 301 is snapped inside the sealing housing 201. Then, it is connected to one side of the pipeline through the second internal thread 302. Next, the elastic rubber ring 4 is pressed into the limiting groove 103 formed on the surface of the flow-blocking housing 101, thereby improving the sealing performance at the joint interface. Then, the assembled whole is connected together through the second external thread 106 and the first internal thread 202. The anti-slip groove 203 provided on the surface of the sealing housing 201 can effectively prevent slipping during installation. Finally, the other side of the pipeline is connected to the other end of the joint through the first external thread 102.

[0032] When the water flow is flowing in the pipeline, it is blocked when reaching the top of the flow-blocking housing 101. The kinetic energy of the water flow decreases, the speed reduces, and it fills the flow-blocking head 104. When the water volume in the flow-blocking head 104 reaches a certain fullness, the water flows out from the four overflow holes 105 formed on the surface of the flow-blocking head 104, impacting the inner wall of the connecting housing 301, and the flow rate further decreases.

[0033] The inner diameter of the connecting housing 301 of this joint is the same as the outer diameter of the end of the flow-blocking housing 101 provided with the first external thread 102. Therefore, when needed, multiple joints can be connected end to end to achieve multiple buffering of the water flow.

[0034] The preferred embodiments of the present utility model disclosed above are only used to help illustrate the present utility model. The preferred embodiments do not elaborate on all details, nor do they limit the present utility model to the specific embodiments described. Obviously, many modifications and variations can be made according to the content of this specification. These embodiments are selected and specifically described in this specification to better explain the principle and practical application of the present utility model, so that those skilled in the relevant technical field can well understand and utilize the present utility model.
