Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage system technology, specifically to a seepage prevention structure for water supply and drainage in building engineering. Background Technology

[0002] Building water supply and drainage engineering refers to projects used for water supply, wastewater discharge, and water quality improvement. It is divided into water supply engineering and drainage engineering. Water supply, sometimes also called water supply, originally referred to urban public water supply projects, which were fundamental infrastructure for urban and industrial development and a major component of municipal engineering. However, in modern times, this term has expanded to include water supply projects for industry, agricultural irrigation, and other water uses. Drainage engineering refers to the pipe and channel systems for discharging wastewater. Currently, most water supply and drainage systems use threaded connections. When water pressure increases, poor sealing can lead to water leakage. Therefore, a seepage-proof structure for water supply and drainage is urgently needed. Utility Model Content

[0003] In order to overcome the problems existing in the background technology, this utility model provides a seepage prevention structure for water supply and drainage in building engineering, so as to solve the technical problem mentioned in the background technology that most water supply and drainage system pipes use threaded connections, and when the water pressure in the pipe increases, the sealing performance is not good, which will lead to water leakage.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: A seepage-proof structure for water supply and drainage in building engineering includes a connecting pipe 1, a connecting pipe 2, an arc-shaped plate 3, and an arc-shaped plate 4. The arc-shaped plate 3 and the arc-shaped plate 4 are formed by dividing a circular pipe into two equal parts along its axis. Flanges 5 are provided at the ends of the connecting pipes 1 and 2. Fixing plates 6 are provided at both ends of the arc-shaped plates 3 and 4 to hold the flanges 5 inside. Connecting plates 7 are provided on both end faces of the arc-shaped plates 3 and 4. The connecting plates 7 of the arc-shaped plates 3 and 4 are connected by bolts to form a seepage-proof component 8. The flanges 5 at the ends of the connecting pipes 1 and 2 are held inside the fixing plates 6 at both ends of the seepage-proof component 8, and the fixing plates 6 and flanges 5 are fixedly connected by bolts. Sealing rubber gaskets are provided between the arc-shaped plates 3 and 4 and between the fixing plates 6 and flanges 5.

[0005] Preferably, the seepage-proof component 8 is provided with a spring 9, and the two ends of the spring 9 rest on the flanges 5 provided on the connecting pipe 1 and the connecting pipe 2, respectively.

[0006] Preferably, the spring 9 is connected to two ends with a fixing ring 10, and a locking bolt 11 is uniformly fixed on the end face of the fixing ring 10. The nut of the locking bolt 11 is fixedly connected to the fixing ring 10. The locking bolt 11 passes through the through hole 12 opened on the flange 5 and the fixing plate 6 from the seepage prevention component 8 and is fixed by a nut.

[0007] Preferably, the through hole 12 on the flange 5 for the locking bolt 11 to pass through is a stepped hole 13, and the larger diameter hole of the stepped hole 13 is a hexagonal hole to facilitate the locking bolt 11 nut to be inserted.

[0008] Preferably, a sealing rubber ring is provided on the stepped surface of the stepped hole 13.

[0009] Preferably, a slot 14 is provided on the end face of the arc plate 2 4 that is in contact with the arc plate 1 3, and an elastic insert 15 is connected to the end face of the arc plate 1 3 that is in contact with the arc plate 2 4 and inserted into the slot 14; sealing rubber sheets are provided on both sides of the slot 14.

[0010] The beneficial effects of this utility model are as follows: By placing the flanges 5 of connecting pipe 1 and connecting pipe 2 inside the seepage prevention component 8 and abutting against the fixed plate 6, when the water pressure inside the seepage prevention component 8 increases, pressure will be applied to the flanges 5, thereby increasing the pressing force between the flanges 5 and the fixed plate 6. In addition, a sealing rubber gasket is provided between the flanges 5 and the fixed plate 6, which further prevents water leakage and improves the seepage prevention effect of the device, while also improving the seepage prevention function of the water supply and drainage system.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.

[0017] like Figure 1-5As shown, this utility model provides a seepage-proof structure for water supply and drainage in building engineering, including a connecting pipe 1, a connecting pipe 2, an arc plate 3, and an arc plate 4; the arc plate 3 and the arc plate 4 are formed by dividing a circular pipe into two parts along its axis; flanges 5 are provided at the ends of the connecting pipe 1 and the connecting pipe 2; fixing plates 6 are provided at both ends of the arc plate 3 and the arc plate 4 to hold the flanges 5 inside; connecting plates 7 are provided on both end faces of the arc plate 3 and the arc plate 4; the connecting plates 7 of the arc plate 3 and the arc plate 4 are connected by bolts to form a seepage-proof component 8; the flanges 5 at the ends of the connecting pipe 1 and the connecting pipe 2 are held inside the fixing plates 6 at both ends of the seepage-proof component 8, and the fixing plates 6 and the flanges 5 are fixedly connected by bolts; sealing rubber gaskets are provided between the arc plate 3 and the arc plate 4 and between the fixing plates 6 and the flanges 5. During installation, the flanges 5 of connecting pipe 1 and connecting pipe 2 are fitted inside the arc-shaped plate 3, contacting the inner side of the fixing plate 6. The fixing plate 6 and flange 5 are then fixedly connected using bolts. Next, the arc-shaped plate 2 4 is placed over the arc-shaped plate 3, covering the flanges 5 at the ends of connecting pipe 1 and connecting pipe 2. The connecting plates 7 on the arc-shaped plate 3 and arc-shaped plate 2 4 are then connected and fixed using bolts. Finally, the fixing plates 6 at both ends of the arc-shaped plate 2 4 are fixedly connected to the flanges 5 using bolts. This invention, by placing the flanges 5 of connecting pipe 1 and connecting pipe 2 inside the seepage-proof component 8 and abutting against the fixing plate 6, increases the pressure on the flanges 5 when the water pressure inside the seepage-proof component 8 increases, thereby increasing the pressure between the flanges 5 and the fixing plate 6. Furthermore, a sealing rubber gasket is placed between the flanges 5 and the fixing plate 6, further preventing water leakage and improving the seepage-proof effect of the device, while also enhancing the seepage-proof function of the water supply and drainage system.

[0018] The seepage-proof component 8 is equipped with a spring 9, with both ends of the spring 9 pressing against the flanges 5 installed on the connecting pipe 1 and the connecting pipe 2, respectively. The spring 9 presses the flanges 5 of the connecting pipe 1 and the connecting pipe 2 onto the fixing plates 6 at both ends of the seepage-proof component 8, facilitating the connection between the connecting pipe 1, the connecting pipe 2 and the seepage-proof component 8, thereby increasing its seepage-proof effect.

[0019] The spring 9 has fixed rings 10 connected to both ends. Locking bolts 11 are evenly fixed to the end faces of the fixed rings 10. The nuts of the locking bolts 11 are fixedly connected to the fixed rings 10. The locking bolts 11 pass through the through holes 12 opened on the flange 5 and the fixed plate 6 from the seepage-proof component 8, and are fixed by nuts. Through the elastic force of the spring 9, the locking bolts 11 pass through the through holes 12 from inside the seepage-proof component 8, connecting and fixing the flange 5 and the fixed plate 6. The nuts of the locking bolts 11 are pressed against the inner side of the seepage-proof component 8, sealing the through holes 12, thus preventing water leakage from the bolt connection through holes 12. Since the locking bolts 11 are installed from inside the seepage-proof component 8 in the through holes 12 of the fixed plate 6 and the flange 5, firstly, two of the locking bolts 11 are installed in the through holes 12 of the flange 5 and the fixed plate 6 at both ends of the arc-shaped plate 3. Then, using a tool, the upper locking bolt 11 is pushed inward, so that the arc-shaped plate 4 covers the flange 5, allowing the locking bolt 11 to be inserted into the through hole 12 from the inside.

[0020] The through hole 12 on the flange 5 for the locking bolt 11 to pass through is a stepped hole 13. The larger diameter hole in the stepped hole 13 is a hexagonal hole to facilitate the insertion of the locking bolt 11 and the nut. The locking bolt 11 is installed in the through hole 12, and the nut is inserted into the hexagonal hole in the stepped hole 13, thereby facilitating the installation of the nut on the locking bolt 11 from the outside.

[0021] A sealing rubber ring is provided on the stepped surface of the stepped hole 13. This can increase the sealing performance of the locking bolt 11 connection and prevent water leakage from the locking bolt 11.

[0022] A slot 14 is provided on the end face of the arc-shaped plate 3 that fits against the arc-shaped plate 4. An elastic insert 15 is connected to the end face of the arc-shaped plate 4 that fits against the arc-shaped plate 3 and is inserted into the slot 14. Sealing rubber sheets are provided on both sides of the slot 14. When the arc-shaped plate 3 and the arc-shaped plate 4 are installed together, the insert 15 is inserted into the slot 14, and then the connecting plate 7 is connected and fixed with bolts. The insert 15 blocks water, preventing water leakage from the joint gap of the connecting plate 7. The sealing rubber sheets increase the sealing performance of the insert 15 in the slot 14, improving the anti-seepage function.

[0023] Work process: During installation, the flanges 5 of connecting pipe 1 and connecting pipe 2 are inserted into the arc plate 3 and contact the inner side of the fixing plate 6. The spring 9 is placed on the arc plate 3, and the locking bolt 11 is inserted into the through hole 12 of the flange 5 and the fixing plate 6 and fixed with a nut. Then, the arc plate 2 is placed on the arc plate 3 to cover the flanges 5 at the ends of connecting pipe 1 and connecting pipe 2. The insert 15 is inserted into the slot 14, and the locking bolt 11 is inserted into the through hole 12 of the fixing plate 6 and the flange 5 of the arc plate 2 and fixed with a nut. Finally, the connecting plates 7 on the arc plate 1 and the arc plate 2 are connected with bolts, thereby connecting and fixing the arc plate 1 and the arc plate 2.

[0024] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
