Description

Technical Field

[0001] This invention belongs to the field of pipeline connection technology, and particularly relates to a sealing structure for a water pipe joint. Background Technology

[0002] Traditional water pipe joint sealing mainly relies on wrapping soft sealing tape around the threaded surface or using built-in elastic sealing rings, which has the following problems:

[0003] High operational experience required: This method involves wrapping a soft sealing tape (such as PTFE tape) around the threaded surface. This requires a high level of experience from the installer, and the tightness is difficult to control precisely, which can easily lead to leakage due to improper operation.

[0004] Low sealing reliability: When an elastic sealing ring is installed inside the joint or at the threaded port, gaps may appear in the sealing ring due to pressure changes under high temperature, high pressure or vibration conditions, reducing sealing reliability.

[0005] High construction complexity: Some sealing solutions use sealants, sealant pastes and other materials to enhance the sealing effect, but these materials usually require additional tools, are complicated to apply, and are prone to aging and failure.

[0006] Therefore, existing technologies still have certain shortcomings in terms of ease of installation, sealing reliability, and structural optimization, and there is an urgent need for an improved sealing structure to enhance the sealing performance of water pipe joints. Summary of the Invention

[0007] In view of the above-mentioned problems in the prior art, the present invention provides a water pipe joint sealing structure that can achieve dual sealing between the box and the outside world, and between the water pipe and the outside world. The structure is simple and the sealing reliability is high.

[0008] To achieve the above objectives, the technical solution provided by the present invention is as follows:

[0009] This application provides a water pipe joint sealing structure, including:

[0010] Enclosure; sealing gasket, including a sealing part and a locking part connected to the sealing part, the sealing part being arranged on the circumferential wall of the mounting hole of the enclosure, and the locking part being arranged on the outer wall of the enclosure;

[0011] The water pipe passes through the central hole of the sealing part and extends into the box body;

[0012] A water pipe connector includes a connector part, a clamping part, and a fixing part connected in sequence. The clamping part is in contact with the sealing part, and the fixing part is located on the side of the locking part away from the housing. When the fixing part moves toward the housing, it can drive the clamping part to squeeze the sealing part.

[0013] The fastener is used to move the fixing part towards the housing and lock the fixing part and the locking part to the housing.

[0014] Optionally, the end face of the water pipe is fitted to the joint through an end face buffer pad.

[0015] Optionally, the inner cavity of the pressing part is provided with a tapered guide surface, the inner diameter of the tapered guide surface near the housing is larger than the inner diameter of the side near the joint, and the sealing part is provided with a sealing surface that matches the tapered guide surface.

[0016] Optionally, the angle between the tapered guide surface and the outer wall of the water pipe is 15° to 30°.

[0017] Optionally, the inner cavity of the pressing part is provided with an arc-shaped guide surface, the inner diameter of which gradually decreases from the side near the housing to the side near the joint, and the sealing part is provided with a sealing surface that matches the arc-shaped guide surface.

[0022] Optionally, the water pipe fitting, water pipe, and sealing gasket are arranged coaxially.

[0023] Compared with the prior art, this application has at least the following beneficial effects:

[0024] In this invention, when the fixing component moves the fixing part towards the housing to lock the fixing part and locking part to the housing, it can guide and drive the pressing part to squeeze the sealing part, causing the sealing part to compress and deform, thus achieving a reliable seal. No additional sealing tape is required, making installation simple and operation easy. By setting an end face buffer pad, it can not only achieve a sealing effect but also effectively avoid rigid contact between the water pipe and the water pipe joint, preventing damage to the water pipe.

[0029] The technical solutions of the 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, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0030] Example 1:

[0031] like Figure 1 As shown, a water pipe joint sealing structure includes:

[0032] Box 5;

[0033] The sealing gasket 3 includes a sealing part 31 and a locking part 32 connected to the sealing part 31. The sealing part 31 is arranged on the circumferential wall of the mounting hole of the housing 5, and the locking part 32 is arranged on the outer wall of the housing 5.

[0034] Water pipe 4 is inserted into the center hole of sealing part 31 and extends into box body 5;

[0035] The water pipe connector 1 includes a connector part 11, a clamping part 12 and a fixing part 13 connected in sequence. The clamping part 12 fits against the sealing part 31. The fixing part 13 is located on the side of the locking part 32 away from the housing 5. When the fixing part 13 moves toward the housing 5, it can drive the clamping part 12 to squeeze the sealing part 31.

[0036] The fixing part 6 is used to move the fixing part 13 toward the housing 5 and lock the fixing part 13, the locking part 32 and the housing 5.

[0037] During installation, the fixing part 6 is operated to move the fixing part 13 towards the housing 5. When the fixing part 13 and the locking part 32 are locked with the housing 5, the locking part 32 of the sealing gasket 3 is compressed, filling the tiny gap between the joint and the housing 5 to form a stable seal. It also guides and drives the pressing part 12 to squeeze the sealing part 31, and the sealing part 31 is compressed and deformed to achieve a reliable seal. No additional sealing bag is required, the installation is simple, and the operation is easy.

[0038] Example 2:

[0039] The difference between this embodiment and Embodiment 1 is that the inner cavity of the pressing part 12 is provided with a tapered guide surface. The inner diameter of the tapered guide surface near the housing 5 is larger than the inner diameter of the side near the connector 11. The sealing part 31 is provided with a sealing surface that matches the tapered guide surface. Under pressure, the tapered guide surface can guide the sealing part 31 of the sealing gasket 3 to undergo radial compression deformation, so that a stable and reliable linear seal is formed between the sealing gasket 3 and the water pipe 4 and the water pipe connector, providing a strong guarantee for the sealing performance of the system.

[0040] The angle between the tapered guide surface and the outer wall of water pipe 4 is 15°~30°.

[0041] The end face of the water pipe 4 is fitted to the connector 11 via the end face buffer pad 2. In this embodiment, the connector 11 has a right-angle groove, the outer wall of the water pipe 4 is fitted to one side wall of the right-angle groove, and the end face of the water pipe 4 is fitted to the other side wall of the right-angle groove via the end face buffer pad 2. By setting the end face buffer pad 2, a sealing effect can be achieved, and rigid contact between the water pipe 4 and the water pipe connector 1 can be effectively avoided, preventing damage to the water pipe 4.

[0042] Water pipe connector 1, water pipe 4, and sealing gasket 3 are installed in a coaxial manner.

[0043] In this embodiment, the locking part 32 of the sealing gasket 3 is perpendicular to the sealing part 31 and has a convex design. The tapered guide surface of the pressing part 12 is also provided with a horizontal section at one end between it and the fixing part 13. The sealing surface of the sealing part 31 is in contact with the pressing part 12 to seal.

[0044] The sealing part 31 is also provided with a mounting groove 33. The side wall of the mounting hole of the housing 5 is engaged in the mounting groove 33. By setting the mounting groove 33, the sealing gasket 3 can be stably fixed on the mounting hole of the housing 5, avoiding the phenomenon of falling off during the assembly process.

[0045] The fastener 6 may include one of bolts or screws, or any other fastener 6 that can achieve pressure locking. In this embodiment, the fastener 6 is a bolt, which passes through the fixing part 13 and the locking part 32 in sequence and is threadedly connected to the housing 5.

[0046] To improve the durability and sealing effect of the sealing gasket 3, in this embodiment the sealing gasket 3 is composed of a three-layer structure, including a flexible rubber layer, a reinforcing support layer and a wear-resistant protective layer connected in sequence.

[0047] For water pipe joints 1 of different sizes, the thickness and width range of the sealing gasket 3 can be adjusted to improve the waterway sealing performance, adapt to water pipe 4 structures of different specifications, and are suitable for a variety of waterway sealing scenarios.

[0048] Example 3

[0049] The difference between this embodiment and embodiment 2 is that the inner cavity of the pressing part 12 is provided with an arc-shaped guide surface. The inner diameter of the arc-shaped guide surface gradually decreases from the side near the housing 5 to the side near the joint part 11. The sealing part 31 is provided with a sealing surface that matches the arc-shaped guide surface. Through this design, under pressure, the arc-shaped guide surface can guide the sealing part 31 of the sealing gasket 3 to undergo radial compression deformation, so that the sealing gasket 3 forms a stable and reliable linear seal with the water pipe 4 and the water pipe joint, providing a strong guarantee for the sealing performance of the system.

[0050] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
