Description

Technical Field

[0001] The utility model relates to the technical field of pipeline accessories, in particular to a pipeline integrated connector which is convenient for pipeline maintenance. Background Art

[0002] The underground water pump room is small, the water pumps are installed compactly, all connections are hard-wired, the gaps cannot be adjusted, and it is inconvenient to repair and update related equipment. Therefore, it is necessary to install a pipeline integrated connector to facilitate pipeline maintenance.

[0003] When there are obvious changes in water pressure, flow rate, etc. in the water flow inside the pipeline, the existing pipeline integrated connector cannot effectively buffer the internal pressure changes, resulting in a large impact on the pipeline and the pipeline connection position. In addition, the pipeline connector is sealed with a simple sealing ring, which has weak pressure resistance and is prone to leakage. Therefore, there is a need for a pipeline integrated connector that is easy to maintain and can withstand higher pressure. Utility Model Content

[0004] The utility model aims to solve the defects in the prior art and provides a pipeline integrated connector which is convenient for pipeline maintenance.

[0005] The utility model is achieved through the following technical solutions:

[0006] A pipeline integrated connector that is convenient for pipeline maintenance, comprising a mounting seat, an adjustment mechanism, a height control rod, a clamping ring and a sealing ring. The adjustment mechanism is clamped on the inner side of the top of the mounting seat, and flanges are provided at the bottom of the mounting seat and the top of the adjustment mechanism. The height control rod is clamped in the flange at the bottom of the mounting seat and the top of the adjustment mechanism. The clamping ring is sleeved on the outside of the adjustment mechanism, and the sealing ring is clamped inside the mounting seat. The adjustment mechanism comprises a connecting pipe, a connecting ring, a bellows, a limiting rod and a plug. The connecting ring is fixedly provided at both ends of the bellows, the bellows equipped with the connecting ring is fixedly provided at the bottom of the connecting pipe, the plug is fixedly provided at the bottom of the connecting ring, and the limiting rod is clamped in the connecting ring.

[0007] In a preferred embodiment of the present invention, the surface of the height control rod is provided with limit nuts on both sides of the top of the connecting pipe and the bottom of the mounting seat;

[0008] The height control rod is mainly used to effectively control the installation depth of the adjustment mechanism to ensure the connection effect between the flange at the end of the adjustment mechanism and the mounting seat and the flange at the end of the pipeline.

[0009] In a preferred embodiment of the present invention, locking nuts are provided on the surface of the limiting rod on both sides of the connecting ring;

[0010] The expansion joint is composed of a limit rod, a bellows and the connecting rings at both ends, which has a certain buffering effect, effectively protects the pipeline and avoids leakage at the connection position.

[0011] In a preferred embodiment of the present invention, a groove cooperating with the sealing ring is provided inside the mounting seat, a slot is provided on the top of the sealing ring, and the vertical cross-section of the sealing ring is a Y-shaped structure.

[0012] In a preferred embodiment of the present invention, the top of the clamping ring is clamped on the inner side of the top of the mounting seat, the bottom of the clamping ring is a conical structure, and the bottom is provided with a circular arc chamfer. The bottom of the clamping ring is clamped into the top slot of the sealing ring, and the clamping ring and the top of the mounting seat are fixed by screws;

[0013] After the clamping ring is clamped into the slot at the top of the sealing ring, as the screw presses the clamping ring down, the conical position at its bottom will continuously apply pressure to the bottom and both sides of the sealing ring, and press the outer side of the sealing ring into the sealing grooves on the inner side of the mounting seat and the outer side of the tube, thereby effectively improving the sealing effect.

[0014] In a preferred embodiment of the present invention, sealing grooves are provided on the inner side of the mounting seat and the outer side of the insertion tube.

[0015] The beneficial effects of the utility model are:

[0016] The integrated pipeline connector, which is convenient for pipeline maintenance, can not only adjust the length to facilitate pipeline maintenance work, but also adds an expansion joint inside that can effectively play a buffering and protective effect, thereby reducing the risk of pipeline damage and leakage at the connection position. The compression ring applies pressure to the sealing ring, making the contact effect between the sealing ring and the mounting seat and the cannula more ideal, thereby achieving a better sealing effect.

[0021] The following detailed description of preferred embodiments of the present invention, combined with the accompanying drawings, will facilitate understanding of the advantages and features of the present invention by those skilled in the art, thereby more clearly defining the scope of protection of the present invention. Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0022] like Figure 1-3 The shown embodiment is a pipeline integrated connector that is convenient for pipeline maintenance, including a mounting seat 1, an adjusting mechanism 2, a height control rod 3, a clamping ring 4 and a sealing ring 5. The adjusting mechanism 2 is clamped on the inner side of the top of the mounting seat 1, and flanges are provided at the bottom of the mounting seat 1 and the top of the adjusting mechanism 2. The height control rod 3 is clamped in the flanges at the bottom of the mounting seat 1 and the top of the adjusting mechanism 2. The clamping ring 4 is sleeved on the outside of the adjusting mechanism 2, and the sealing ring 5 is clamped inside the mounting seat 1. The adjusting mechanism 2 includes a connecting pipe 21, a connecting ring 22, a bellows 23, a limiting rod 24 and an insert 25. The connecting ring 22 is fixedly provided at both ends of the bellows 23, the bellows 23 with the connecting ring 22 is fixedly provided at the bottom of the connecting pipe 21, the insert 25 is fixedly provided at the bottom of the connecting ring 22, and the limiting rod 24 is clamped in the connecting ring 22.

[0023] Specifically, limit nuts are provided on the surface of the height control rod 3, located on the top of the connecting tube 21 and on both sides of the bottom of the mounting seat 1; locking nuts are provided on the surface of the limit rod 24, located on both sides of the connecting ring 22; a slot cooperating with the sealing ring 5 is provided inside the mounting seat 1; a slot is provided on the top of the sealing ring 5; the vertical cross-section of the sealing ring 5 is a Y-shaped structure; the top of the clamping ring 4 is clamped on the inner side of the top of the mounting seat 1; the bottom of the clamping ring 4 is a conical structure, and a circular chamfer is provided on the bottom; the bottom of the clamping ring 4 is clamped into the slot at the top of the sealing ring 5; the clamping ring 4 is fixed to the top of the mounting seat 1 by screws, and a sealing groove is provided on the inner side of the mounting seat 1 and the outer side of the insert 25.

[0024] In this embodiment, the entire pipeline integrated connector is connected to the pipeline end flange through the flange at the mounting base 1 and the end of the connecting pipe 21 to complete the installation work. When the pipeline in the pipeline network needs to be replaced and repaired, in order to provide sufficient space, the length of the pipeline integrated connector needs to be adjusted. At this time, it is only necessary to rotate the mounting screw on the outside of the clamping ring 4 to separate the clamping ring 4 from the mounting base 1, and adjust the limit nut on the surface of the height control rod 3. The position of the adjustment mechanism 2 can be controlled by telescopically controlling the insertion tube 25 inside the mounting base 1, thereby reserving sufficient space to facilitate pipeline disassembly or installation.

[0025] Furthermore, when the pipeline replacement is completed, the pipeline integrated connector is installed again. First, after the mounting base 1 and the end flange of the connecting pipe 21 are connected to the end flange of the pipeline, the limit nut is rotated according to the length of the integrated connector so that the limit nut on the surface of the height control rod 3 clamps the two sides of the flange to achieve effective fixation, and then the screws on the outside of the clamping ring 4 are screwed in. At this time, the conical area at the bottom of the clamping ring 4 will be inserted into the top slot of the sealing ring 5, and the top of the sealing ring 5 will be opened. As the clamping ring 4 is pressed down, the sealing ring 5 is squeezed by the insert pipe 25 and the inner wall of the mounting base 1, and the rubber sealing ring 5 will be pressed into the sealing groove on the outside of the insert pipe 25 and the inner wall of the mounting base 1, thereby effectively achieving sealing and can withstand greater internal pressure than ordinary connectors. Between the insert pipe 25 and the connecting pipe 21, the expansion joint composed of the connecting ring 22, the bellows 23 and the limit rod 24 can effectively protect the pipeline and reduce the risk of leakage at the connection position when the internal pressure changes, thereby improving the reliability and safety of pipeline transmission.
