Description

Technical Field

[0001] This application belongs to the field of press-fit connector technology and relates to a press-fit portal compensator. Background Technology

[0002] In the process of developing this invention, the inventors discovered at least the following problems in the prior art: Thin-walled stainless steel pipes are widely used in building water supply and drainage, gas transmission and other fields due to their corrosion resistance, high pressure resistance and good sealing performance. However, existing press-fit connection technology often fails to provide sufficient compensation capacity when facing complex working conditions, such as temperature changes and pressure fluctuations, leading to leakage at the connection or pipe damage, affecting the stability and safety of the system.

[0003] Therefore, how to provide a compression-type portal compensator to provide compensation, prevent leakage at the connection, and avoid pipeline damage has become an urgent technical problem to be solved. Utility Model Content

[0004] To overcome the problems existing in related technologies, this application aims to provide a press-fit gate compensator that can provide compensation, prevent leakage at the connection, and prevent pipeline damage.

[0005] This application is achieved through the following technical solution.

[0006] This technical solution provides a clamping-type portal compensator, including:

[0007] Press-fit connector;

[0008] A portal-shaped bend, comprising a pipe A, a pipe B, and a pipe C, both ends of which are sequentially and fixedly connected by bends;

[0009] The portal-shaped bend is configured as a portal-like structure. The crimp connector is fixed to both ends of the portal-shaped bend and is an integral part of it. The bend is a 90-degree bend, and the diameters of pipes A, B, and C are all equal to those of the bend.

[0010] The present invention is further configured such that at least one external threaded interface is provided on the outside of the portal bend, and the external threaded interface is on the same plane as the crimping joint and the portal bend.

[0011] The present invention is further configured such that an external threaded interface is fixed to the outside of the A tube, an interface of the same specification is fixed to the corresponding position of the C tube, and a D tube is detachably connected to the outside of the external threaded interface, with the other end of the D tube installed outside the interface.

[0012] The present invention is further configured such that valves are installed at the ends of pipes A and C that are close to pipe B, and valves are installed inside both the external threaded interface and the pipe in which the interface is located.

[0013] The present invention is further configured such that the diameter of the D-tube is smaller than the diameter of the portal bend, and the D-tube is made of stainless steel.

[0014] The present invention is further configured such that the portal-shaped bend is a thin-walled stainless steel pipe, and the crimp connector is made of stainless steel.

[0015] The present invention is further provided with a rubber sealing ring inside the socket of the crimp connector for sealing the crimp connector and the outer pipe fitting.

[0016] The above technical solution has the following technical effects: the continuous bends set by the portal bend provide sufficient compensation for pipelines due to temperature changes and pressure fluctuations, improve pipeline stability, reduce the number of pipeline crimp joints, thereby reducing leakage risk, and can adapt to different installation environments and angle requirements. At the same time, the integrated structure with crimp joints can use crimping tools to press the outer convex rings on both sides of the pipe fitting socket to form a seal between the pipe fittings, thus achieving a stable connection of the pipeline.

[0024] The technical solutions of some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a clamping-type portal compensator, such as Figures 1-4 As shown, it includes:

[0027] 1. Press-fit connector;

[0028] The portal bend 2 includes pipe A 3, pipe B 4 and pipe C 5, which are fixedly connected in sequence at both ends by bends 6.

[0029] The portal bend 2 is designed with a portal-like structure. The crimp connector 1 is fixed to both ends of the portal bend 2 and is an integral part of it. The bend 6 is a 90-degree bend. The diameters of pipes A 3, B 4, C 5 and bend 6 are all the same.

[0030] It should be noted that the portal bend 2 adopts a portal-like design to provide sufficient compensation for pipelines to change in temperature and pressure, reducing the risk of pull-out; the connection method of the crimp connector 1, that is, adding crimp connectors 1 at both ends of the portal bend 2 to form an integrated design, can reduce the number of pipeline crimping joints and facilitate quick and reliable connection with other pipeline systems.

[0031] like Figure 3 As shown, the portal bend 2 is provided with at least one external threaded interface 7 on its exterior. The external threaded interface 7 is on the same plane as the crimp connector 1 and the portal bend 2.

[0032] like Figure 4 As shown, an external threaded interface 7 is fixed to the outside of pipe A 3, and an interface of the same specification is fixed to the corresponding position of pipe C 5. Pipe D 8 is detachably connected to the outside of the external threaded interface 7, and the other end of pipe D 8 is installed on the outside of the interface.

[0033] like Figure 4 As shown, valves 9 are installed at the ends of pipes A 3 and C 5 near pipe B 4, and valves are installed inside both the external threaded interface 7 and the pipes where the interface is located.

[0034] It should be noted that by setting up pipe D8 and installing valve 9, two parallel passages can be formed. Pipe D8 can be used when the flow rate is low, while pipe B4 can be used when the flow rate is high. At the same time, pipe D8 serves as the primary passage, and if it is damaged, the valve can be closed to facilitate maintenance.

[0035] like Figure 4 As shown, the diameter of pipe D8 is smaller than that of the portal bend 2, and pipe D8 is made of stainless steel.

[0036] like Figures 1-4 As shown, the portal bend 2 is a thin-walled stainless steel pipe, and the crimp fitting 1 is made of stainless steel.

[0037] like Figures 1-4 As shown, a rubber sealing ring is provided inside the socket of the crimp connector 1 to seal the crimp connector 1 and the outer pipe fitting. It should be noted that when the crimp connector 1 and the outer pipe fitting are connected by a crimping tool, the deformed part will squeeze the sealing ring to form an interference fit, thereby achieving a seal.

[0038] Working principle: The continuous bends set by the portal bend 2 provide sufficient compensation for pipelines to change temperature and pressure, improve pipeline stability, reduce the number of pipeline crimping joints, and thus reduce leakage risk. It can adapt to different installation environments and angle requirements. At the same time, the integrated structure with crimping joint 1 can use crimping tools to press the two sides of the outer convex ring set on the pipe fitting interface to form a seal between the pipe fittings, and achieve a stable connection of the pipeline.

[0039] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
