Description

Technical Field

[0001] The utility model relates to the technical field of water supply pipe sealing structures, in particular to a new W-shaped pipeline seal. Background Art

[0002] Pipe connection is a very important part of drainage project construction and is directly related to the quality of the project. In urban drainage systems, common pipe connection methods include rubber connection, threaded connection, flange connection, hot melt connection, etc. Each connection method has its applicable scenarios and characteristics. The quality of pipe connection directly determines the reliability and durability of the project. High-quality connection materials and technologies can effectively prevent inflow and infiltration, which can not only ensure the water quality and quantity of drainage, but also extend the service life of the pipe.

[0003] As a sealing type of water supply pipe interface, the rubber ring is mainly used to expand one end of the pipe into a socket with a concave channel through an automatic expanding machine, and then a flexible rubber sealing ring is placed on it. The other end of the pipe that has not been expanded is inserted into the socket with the sealing ring installed to complete the connection. In the traditional sealing design of underground pipe junctions, the cross-section of the sealing rubber ring is wedge-shaped or circular. This design can seal the intersection of two underground pipes and ensure the normal operation of the pipeline system. However, during long-term use, the gasket may have some problems, such as loose connection bayonet, easy damage, and reduced sealing performance. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a W-shaped new pipeline seal. In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0005] A new W-shaped pipe seal is installed between a socket and a plug. The socket and the plug are plugged together and include a gasket. The gasket is a circular ring structure with a W-shaped cross section. The inner wall of the gasket coincides with the outer wall of the plug. The socket is provided with an inner cavity that matches the plug, and a concave cavity that accommodates the gasket and matches the gasket is opened in the inner cavity.

[0006] Furthermore, a plurality of grooves arranged in a circular array are formed on both sides of the gasket.

[0007] Furthermore, a circular groove perpendicular to the central axis of the gasket is opened in the middle of the gasket, and the groove extends from the inner wall of the gasket toward the outer wall.

[0008] Furthermore, the inner wall port of the gasket is arranged in an arc shape.

[0009] Furthermore, an annular extrusion ring is fixedly connected in the concave cavity, and the extrusion ring is located on the side surface of the gasket.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The device places the pipe plug into the socket through mechanical or manual alignment, changes the original single circular gasket into a W-shape, and increases the bayonet contact points from 1 to 2. By optimizing the sealing structure, the reliability and durability of the seal are improved. The sealing structure can better adapt to pipe deformation and improve the sealing effect.

[0016] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Embodiment 1:

[0018] like Figure 1 , Figure 2 As shown, the utility model provides a technical solution, a W-shaped new type of pipe seal, installed between a socket 1 and a plug 2, the socket 1 and the plug 2 are plugged together, including a gasket 3, the gasket 3 is a circular ring structure, the cross-section of the gasket 3 is W-shaped, the inner wall of the gasket 3 coincides with the outer wall of the plug 2, the socket 1 is provided with an inner cavity 4 matched with the plug 2, and the inner cavity 4 is provided with a concave cavity 5 for accommodating the gasket 3 and matching with the gasket 3.

[0019] It should be noted that the sealing ring used as a flexible connection form usually adopts a sealing ring slide-in connection, and the specific connection is a socket connection.

[0020] The working principle is: the first step is cleaning. Before connection, clean and check the position of the socket 1 to ensure that there are no impurities such as bumps that may damage the sealing structure;

[0021] The second step is lubrication. Grease the sealing position of the socket 1 to ensure the lubrication effect between the seal and the socket 1.

[0022] The third step is to install the seal. Insert the "W" washer 3 into the concave cavity 5 of the socket 1 and press it tightly. The main function of the washer 3 is sealing. After putting it into the concave cavity 5, check it. If it is qualified, brush it with butter evenly;

[0023] The fourth step is alignment. Before docking, the line type of the plug 2 should be adjusted. According to the size of the plug 2 and the concave cavity 5 of the socket 1, the plane position of the pipeline should be partially adjusted to ensure the straightness of the plug 2 and the tightness of the plug connection;

[0024] The fifth step is pipe connection. Place the plug 2 into the socket 1 through mechanical or manual alignment. Due to the position of the plug 2 and the treatment of the socket 1, the pipe can be easily installed successfully after a slight external force is applied.

[0025] The buckle structure cross section on the W-shaped gasket 3 is designed to be rectangular, such as Figure 1 As shown, it can also be designed into a prism shape, so that the gasket 3 and the cavity 5 fit more closely. Compared with the traditional gasket structure, the W-shaped gasket 3 structure designed in this patent has one more contact point, is more stable, can better adapt to the deformation and vibration of the pipeline, and improves the sealing effect.

[0026] In this embodiment, the inner wall port of the gasket 3 is arranged in an arc shape, so as to facilitate the smooth insertion of the plug 2 into the socket 1 and make the connection more efficient.

[0027] Embodiment 2:

[0028] On the basis of Example 1, Figure 1 , Figure 2 As shown, a plurality of grooves 6 arranged in an annular array are provided on both sides of the gasket 3. After the gasket 3 is inserted into the concave cavity 5, the air between the gasket 3 and the concave cavity 5 is discharged through the grooves 6, so that the gasket 3 and the concave cavity 5 fit more tightly, which facilitates the gasket 3 to be pressed into the concave cavity 5.

[0029] Embodiment 3:

[0030] On the basis of Example 1 or Example 2, Figure 1 As shown, the middle of the gasket 3 is provided with an annular groove 7 perpendicular to the central axis of the gasket 3, and the groove 7 extends from the inner wall to the outer wall of the gasket 3. When the gasket 3 is inserted into the cavity 5, the two ends of the gasket 3 can be squeezed to make the gasket 3 and the cavity 5 fit more tightly, without affecting the sealing function of the gasket 3.

[0031] Embodiment 4:

[0032] On the basis of Example 1 or Example 2 or Example 3, Figure 1As shown, an annular extrusion ring 8 is fixedly connected in the concave cavity 5, and the extrusion ring 8 is located on the side of the gasket 3. During the matching process between the gasket 3 and the concave cavity 5, the extrusion ring 8 is used to squeeze the gasket 3, so that the gasket 3 and the concave cavity 5 are matched more tightly.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
