Description

Technical Field

[0001] The utility model belongs to the technical field of water supply pipelines, and particularly relates to a sealing support at the butt joint of engineering water supply pipelines. Background Technique

[0002] The sealing support at the butt joint of engineering water supply pipelines generally refers to a component used for sealing and supporting the pipeline connection. This kind of support is usually made of materials such as rubber, polyurethane or silica gel, and has good sealing performance and bearing capacity. Its function is to form a reliable seal at the pipeline butt joint, prevent water flow or pressure loss, and support the pipeline to ensure the stability and safety of the pipeline connection.

[0003] However, after the sealing support docks and fixes the butt joints of two water supply pipelines, the two ends of the butt joint of the water supply pipeline are in a suspended state at this time. When the water supply pipeline is in normal water supply use, the water flow will generate weight when passing through the pipeline, and the weight generated when the water flow passes through will act on the sealing support and the butt joint of the water supply pipeline, which will easily cause the butt joint of the water supply pipeline to break, thus resulting in leakage when the water supply pipeline supplies water. Content of the Utility Model

[0004] The purpose of the utility model is to provide a sealing support at the butt joint of engineering water supply pipelines to solve the problem that when the water supply pipeline is in normal water supply use, the water flow will generate weight when passing through the pipeline, and the weight generated when the water flow passes through will act on the sealing support and the butt joint of the water supply pipeline, which will easily cause the butt joint of the water supply pipeline to break as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A sealing support at the butt joint of engineering water supply pipelines, including a semi-circular sealing ring A and a semi-circular sealing ring B symmetrically arranged above the semi-circular sealing ring A. The semi-circular openings of the semi-circular sealing ring A and the semi-circular sealing ring B face upwards and downwards respectively. The shapes, sizes, structural compositions and thicknesses of the semi-circular sealing ring A and the semi-circular sealing ring B are respectively the same. A U-shaped support seat is welded to the bottom of the semi-circular sealing ring A, and a support seat fixing bottom plate is fixed to the bottom of the U-shaped support seat. Pipe lifting and fixing devices are arranged at the centers of the front and rear ends of the U-shaped support seat and the support seat fixing bottom plate.

[0006] The pipe lifting and fixing device at the front end of the U-shaped support seat and the support seat fixing bottom plate includes a ground-attached support strip, an arc-shaped lifting strip and an arc-shaped support frame. The ground-attached support strip is welded to the front end of the U-shaped support seat and the support seat fixing bottom plate. Arc-shaped support frames are welded to the tops of the left and right ends of the ground-attached support strip. An arc-shaped lifting strip is connected to the tops of the two arc-shaped support frames, and the arc-shaped lifting strip is fixedly connected to the arc-shaped support frame by welding.

[0007] Preferably, the pipe lifting and fixing device further includes a contact protection pad, which is made of soft rubber and adhered to the outer wall of the top end of the arc-shaped lifting strip plate. The outer wall of the bottom of the ground contact support strip plate is flush with the outer wall of the bottom of the support fixed bottom plate.

[0008] Preferably, a thickened sealing gasket A is arranged on the inner arc wall of the semi-circular sealing ring A, and a thickened sealing gasket B is arranged on the inner arc wall of the semi-circular sealing ring B. The outer arc wall of the top end of the arc-shaped lifting strip plate is flush with the inner arc wall of the center of the bottom end of the thickened sealing gasket A, and the radian of the outer wall of the top end of the arc-shaped lifting strip plate is consistent with the radian of the inner wall of the bottom end of the thickened sealing gasket A.

[0009] Preferably, downwardly concave sealing docking slots are arranged inside the left and right ends of the top of the thickened sealing gasket A, and downwardly protruding sealing docking strips are arranged at the bottom of the left and right ends of the thickened sealing gasket B.

[0010] Preferably, the cross-sectional shapes of the sealing docking strip and the sealing docking slot are both trapezoidal. The sealing docking strip can be completely inserted into the sealing docking slot, and there is an interference fit between the sealing docking strip and the sealing docking slot.

[0011] Preferably, support connecting frames A are welded to both ends of the left end of the top of the semi-circular sealing ring A, and support connecting frames B are welded to both ends of the left and right of the bottom of the semi-circular sealing ring B. The support connecting frame A and the support connecting frame B are fixedly connected by a plurality of fixing bolts.

[0012] Compared with the prior art, the present utility model provides a sealing support for the butt joint of a water supply pipeline for engineering, which has the following beneficial effects:

[0013] In the present utility model, a new type of pipe lifting and fixing device is added to the front and rear ends of the U-shaped support seat and the support fixed bottom plate of the sealing support for the butt joint of the water supply pipeline for engineering. When the water supply pipeline is sealed and fixed by the semi-circular sealing ring A and the semi-circular sealing ring B at the top end of the U-shaped support seat, at this time, the two pipe lifting and fixing devices respectively lift and support the bottom of the front and rear ends of the fixed water supply pipeline. In this way, the pipe lifting device can generate a lifting and fixing effect at the bottom of the two ends of the fixed part of the water supply pipeline, avoiding the situation that the weight when the water flows through inside the water supply pipeline is concentrated at the sealing and fixing part, resulting in fracture and damage at the sealing and fixing part. Because the bottom of the front and rear ends of the sealing and fixing part of the water supply pipeline is lifted and supported upward by the pipe lifting and fixing device, it can help the sealing and fixing part share the weight pressure generated during water supply, thereby preventing the sealing and fixing part from being stressed concentratedly and causing fracture and damage.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] The present utility model provides a sealing support at the docking joint of a water supply pipeline for engineering use as shown in Figures 1-4 Figure, which includes a semi-circular sealing ring A4 and a semi-circular sealing ring B5 symmetrically arranged above the semi-circular sealing ring A4. The semi-circular openings of the semi-circular sealing ring A4 and the semi-circular sealing ring B5 face upward and downward respectively. The shapes, sizes, structural compositions, and thicknesses of the semi-circular sealing ring A4 and the semi-circular sealing ring B5 are respectively the same. The bottom of the semi-circular sealing ring A4 is welded with a U-shaped support seat 3, and the bottom of the U-shaped support seat 3 is fixed with a support fixing bottom plate 1. The inner parts of the left and right ends at the top of the thickened sealing gasket A7 are both provided with downwardly concave sealing docking slots 10. The left and right ends at the bottom of the thickened sealing gasket B6 are both provided with downwardly protruding sealing docking strips 12. The cross-sectional shapes of the sealing docking strips 12 and the sealing docking slots 10 are both trapezoidal. The sealing docking strips 12 can be completely inserted into the sealing docking slots 10, and there is an interference fit between the sealing docking strips 12 and the sealing docking slots 10. The left and right ends at the top of the semi-circular sealing ring A4 are both welded with support connecting frames A8, and the left and right ends at the bottom of the semi-circular sealing ring B5 are both welded with support connecting frames B9. And the support connecting frames A8 and the support connecting frames B9 are fixedly connected by a plurality of fixing bolts 11.

[0021] As Figure 1 、 Figure 2 and Figure 3 shown, when installing and using the sealing support at the butt joint of the water supply pipeline for the project, first, it is necessary to determine the butt joint of the water supply pipeline. Then, the U-shaped support base 3 needs to be placed on the ground through the support fixing base plate 1 at the bottom. Then, the support fixing base plate 1 needs to be firmly fixed to the ground through multiple bolts. And before fixing, it is necessary to ensure that the semi-circular sealing ring A4 at the top of the U-shaped support base 3 is aligned with the direction of the water supply pipeline, that is, the water supply pipeline can be normally placed inside the arc of the semi-circular sealing ring A4. Then, both butt joints of the two water supply pipelines need to be placed into the thickened sealing washer A7 inside the semi-circular sealing ring A4. Then, the semi-circular sealing ring B5 is placed with its opening facing downwards on the upper side of the butt joint of the two water supply pipelines. Then, the semi-circular sealing ring B5 is sleeved on the outer upper half of the butt joint of the two water supply pipelines through the thickened sealing washer B6. Then, it is necessary to use the fixing bolt 11 to fixedly connect the support connecting frame A8 and the support connecting frame B9 at the left and right ends of the semi-circular sealing ring A4 and the semi-circular sealing ring B5. When the fixing bolt 11 is slowly tightened, the semi-circular sealing ring A4 and the semi-circular sealing ring B5 will approach each other, so that the thickened sealing washer A7 and the thickened sealing washer B6 are firmly sealed outside the butt joint of the two water supply pipelines. After the sealing butt joint insert 12 on the thickened sealing washer B6 is firmly inserted into the sealing butt joint slot 10 inside the thickened sealing washer A7, the two thickened sealing washers will produce a sealing effect at the butt joint of the water supply pipeline, thus being able to prevent the situation that water leaks through the pipeline butt joint when supplying water.

[0022] As Figure 1 and Figure 4 shown, pipeline lifting and fixing devices 2 are provided at the centers of the front and rear ends of the U-shaped support base 3 and the support fixing base plate 1. The pipeline lifting and fixing device 2 at the front end of the U-shaped support base 3 and the support fixing base plate 1 includes a ground-attached support strip plate 13, an arc-shaped lifting strip plate 14, and an arc-shaped support frame 16. The ground-attached support strip plate 13 is welded to the front end of the U-shaped support base 3 and the support fixing base plate 1. Arc-shaped support frames 16 are welded to the tops of the left and right ends of the ground-attached support strip plate 13. An arc-shaped lifting strip plate 14 is connected to the tops of the two arc-shaped support frames 16. The arc-shaped lifting strip plate 14 is fixedly connected to the arc-shaped support frame 16 by welding. The pipeline lifting and fixing device 2 further includes a contact protection pad 15. The contact protection pad 15 is made of soft rubber, and the contact protection pad 15 is bonded to the outer wall of the top of the arc-shaped lifting strip plate 14. The outer wall of the bottom of the ground-attached support strip plate 13 is flush with the outer wall of the bottom of the support fixing base plate 1.

[0023] As Figure 1 and Figure 4As shown in the figure, a thickened sealing washer A7 is provided on the arc-shaped inner wall of the semi-circular sealing ring A4, and a thickened sealing washer B6 is provided on the arc-shaped inner wall of the semi-circular sealing ring B5. The arc-shaped outer wall at the top of the arc-shaped supporting strip 14 is flush with the arc-shaped inner wall at the center of the bottom end of the thickened sealing washer A7, and the radian of the outer wall at the top of the arc-shaped supporting strip 14 is consistent with the radian of the inner wall at the bottom end of the thickened sealing washer A7. After the butt joint of the two water supply pipes is sealed and fixed by this sealing support, the arc-shaped supporting strips 14 on the two pipe supporting and fixing devices 2 are respectively attached to the bottoms of the front and rear ends of the butt joint pipe through the contact protection pads 15, and the contact protection pads 15 can completely fit the bottom of the pipe, so as to protect the bottom of the pipe. The ground-attached supporting strip 13 generates a supporting and fixing effect at the bottom of the arc-shaped supporting strip 14 through the two arc-shaped supporting strips, so as to ensure that the arc-shaped supporting strip 14 can always be in the best state to generate a supporting and lifting effect at the bottom of the water supply pipe. When water is supplied inside the water supply pipe, the weight generated by the water flow will press down the water supply pipe, and the arc-shaped supporting strips 14 supporting the bottoms of both ends of the butt joint of the water supply pipe can resist the weight pressure generated by the water flow together with the sealing support, preventing the weight pressure generated when the water flow passes through from concentrating on the connection of the sealing support and causing the pipe connection to break. Only in this way can it be ensured that the butt joint of the water supply pipe is always in a sealed state and leakage is avoided.

[0024] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
