Description

Technical Field

[0001] This application relates to the technical field of indoor pipeline installation and anti-leakage, and particularly relates to an anti-leakage structure for indoor decoration pipelines. Background Art

[0002] Currently, PVC, PPR and other plastic pipelines or metal pipelines are commonly used for indoor decoration pipeline installation, and are fixed by means such as gluing, hot melting or threaded connection. With the improvement of decoration standards, the problem of pipeline leakage has become the focus of complaints, especially the leakage at joints caused by material aging, temperature difference deformation or construction errors.

[0003] In recent years, the industry has tried to alleviate the problem by improving the sealing ring material (such as EPDM rubber), adding a waterproof layer (such as polyurethane coating) or introducing intelligent monitoring (such as humidity sensors), etc. However, the cost is high or the maintenance is complex, making it difficult to popularize.

[0004] Conventional anti-leakage means in the prior art include: Multi-layer sealant winding method: winding raw tape or applying sealant at the pipeline joint, but it overly relies on the operation accuracy of workers, is prone to cracking after long-term use, has low construction efficiency and poor durability, and is easy to peel off under temperature difference; Pre-set rubber ring seal: pre-installing an O-ring at the pipe fitting connection, but it has high requirements for the processing accuracy of the pipeline, the rubber is prone to aging and failure, and at the same time it has strict requirements for the concentricity of the pipeline, which is difficult to guarantee in actual installation; External waterproof casing: wrapping a flexible waterproof casing (such as a stainless steel bellows) outside the pipeline. Although it can buffer deformation, it cannot solve the interface leakage problem, occupies a large space, and it can only protect against external water vapor and cannot prevent the internal leakage of the pipeline from spreading to the wall; Therefore, in view of the above related technical problems, an anti-leakage structure for indoor decoration pipelines with good sealing performance, simple installation and effective anti-seepage is proposed. Summary of the Invention

[0005] In order to improve the above problems, this application provides an anti-leakage structure for indoor decoration pipelines.

[0006] This application provides an anti-leakage structure for indoor decoration pipelines, adopting the following technical solutions: An anti-leakage structure for indoor decoration pipelines includes a pipeline interface part and a leakage drainage device. A communicating pipe is arranged inside the pipeline interface part, and conical silica gel connection sleeves are connected to both ends of the communicating pipe. Indoor decoration water pipes are inserted into both ends of the pipeline interface part, and one end of the indoor decoration water pipe is inserted into the conical silica gel connection sleeve; One end of the water leakage drainage device is connected with a drainage connecting pipe, and the end of the drainage connecting pipe away from the water leakage drainage device is inserted into the inner bent part of the pipe interface part. A drainage port is arranged at the end of the water leakage drainage device away from the drainage connecting pipe, and an automatic drainage component is connected in the drainage port.

[0007] Preferably, the pipe interface part is an L-shaped hollow pipe fitting, and the pipe interface part is an anti-corrosion galvanized steel pipe. Both the indoor decorative water pipe and the connecting pipe are PVC pipes, and one end of the indoor decorative water pipe is inserted into the connecting pipe.

[0008] Preferably, the large-diameter end of the conical silicone connecting sleeve fits on the inner wall of the pipe interface part, and the small-diameter end of the conical silicone connecting sleeve is nested on the outer side of the indoor decorative water pipe. A sealing pressure ring is arranged on the outer side of the conical silicone connecting sleeve, and an annular connecting groove for fitting with the sealing pressure ring is arranged in the pipe interface part.

[0009] By adopting the above technical scheme, the conical silicone connecting sleeve seals the interface, and after the connection is completed, a ring pressing pipe wrench is used to press and fix it, so that the sealing pressure ring is fitted into the annular connecting groove. Through the self-adaptive pressing and sealing of the conical elastic sealing sleeve, the dependence on the pipe installation accuracy is reduced, and the construction error tolerance rate is increased by more than 40%.

[0010] Preferably, the indoor decorative water pipe and the connecting pipe are connected inside the conical silicone connecting sleeve. A sealing card slot is arranged at the connection between the pipe interface part and the drainage connecting pipe, and a connecting threaded hole is arranged at the center position of the sealing card slot.

[0011] Preferably, one end of the drainage connecting pipe is connected to the connecting threaded hole by thread. A sealing gasket is arranged on the outer side of the drainage connecting pipe, and the sealing gasket is fitted with the sealing card slot. Four groups of symmetric connecting sliding grooves are arranged on the inner wall of the drainage connecting pipe.

[0012] By adopting the above technical scheme, the drainage device is convenient for installation and disassembly, and can be adjusted according to the position of the pipeline. The drainage connecting pipe is connected to the connecting threaded hole by thread. After the drainage connecting pipe is completely screwed into the connecting threaded hole, the sealing gasket is completely fitted into the sealing card slot. Then, according to the placement position and horizontal or vertical state of the pipeline, the connection position of the drainage connecting pipe is selected, so that the water receiving plate and the water leakage alarm are in the direction of the lowest point of the water leakage drainage device, and the plugging connecting pipe is plugged into the connecting sliding groove of the drainage connecting pipe through the connecting block.

[0013] Preferably, a plug-in connecting pipe is provided at one end of the water leakage drainage device close to the drainage connecting pipe, and a water receiving plate in the shape of a semi-cylindrical body is provided at one end of the plug-in connecting pipe away from the water leakage drainage device. The plug-in connecting pipe is inserted into the drainage connecting pipe, and one end of the water receiving plate is attached to the outer wall of the communicating pipe.

[0014] Preferably, a connecting plug block that fits into the connecting sliding groove is provided at the bottom of the plug-in connecting pipe. Multiple guide grooves are provided on the inner wall of the pipe interface part, and one end of each of the multiple guide grooves extends to the sealing clamping groove. A water leakage alarm is connected to the inner wall of the water leakage drainage device on the side close to the water receiving plate.

[0015] By adopting the above technical solution, the water receiving plate and the water leakage alarm are in the direction of the lowest point of the water leakage drainage device. The water leaked from the indoor decorative water pipe and the communicating pipe enters the pipe interface part, and flows through the guide grooves in the pipe interface part to the sealing clamping groove. After the leaked water enters the water leakage drainage device through the drainage connecting pipe, it flows to the lowest point of the water leakage drainage device, that is, the position of the water leakage alarm. The water leakage alarm can be an optoelectronic alarm or a wireless alarm, which is used to notify the outside of the water leakage information at the water leakage and seepage location, so as to facilitate the timely repair of the water leakage location.

[0016] Preferably, the automatic drainage component includes a lifting float ball and a connecting ball valve. The connecting ball valve is rotatably connected in the drainage port, and a switch connecting rod is connected between the lifting float ball and the connecting ball valve.

[0017] Preferably, a drainage hole is provided at one end of the connecting ball valve away from the switch connecting rod, and multiple water inlet holes are provided on one side of the connecting ball valve away from the drainage hole. The multiple water inlet holes are all communicated with the drainage hole.

[0018] Preferably, a floating limit block is connected to the inner wall of the water leakage drainage device on the side away from the water leakage alarm, and the floating limit block is arranged on the arc with the connecting ball valve as the center of the circle of the lifting float ball.

[0019] By adopting the above technical solution, it can be automatically discharged according to the height of the water level of the water leakage. The opening and closing of the drainage port in the water leakage drainage device are controlled by the automatic drainage component. The drainage port is sealed by the connecting ball valve, and the lifting float ball drives the connecting ball valve to rotate in the drainage port through the switch connecting rod. The water in the water leakage drainage device enters the connecting ball valve through the water inlet holes, and the water in the connecting ball valve can be discharged from the drainage hole. When the connecting ball valve rotates to the position where the drainage hole is communicated with the drainage port, the water leakage drainage device can perform the drainage action at this time. When the drainage hole is completely away from the drainage port, the water leakage drainage device does not perform the drainage work at this time. When there is no water in the water leakage drainage device, the automatic drainage component is in the initial position at this time, and the water leakage drainage device does not perform the drainage work at this time.

Compared with the prior art, this indoor decoration pipeline anti-leakage structure has good sealing performance, is simple and fast to install, has low installation precision requirements, and low installation costs. The indoor decoration water pipe is inserted into the pipeline interface part, and the indoor decoration water pipe is connected to the connecting pipe. The tapered silicone connecting sleeve seals the interface. After the connection is completed, the ring pressing pipe wrench is used to press and fix, so that the sealing pressing ring is fitted into the annular connecting groove. The large diameter end of the tapered silicone connecting sleeve fits against the inner wall of the pipeline interface part, and the small diameter end of the tapered silicone connecting sleeve is nested on the outside of the indoor decoration water pipe. The tapered structure of the tapered silicone connecting sleeve can adaptively press and seal, reducing the dependence on the pipeline installation precision.

[0021] 2. Compared with the prior art, this indoor decoration pipeline anti-leakage structure can send out a notification alarm in time when penetration leakage occurs, and can drain the leaked water in time to avoid secondary damage caused by concealed leakage.

The water leaked from the pipeline interface part is received by the water receiving plate, and after the leaked water enters the leakage drainage device through the drainage connecting pipe, it flows to the lowest point of the leakage drainage device, that is, the position where the leaked water flows to the leakage alarm. The leakage alarm can be an optoelectronic alarm or a wireless alarm, which is used to notify the outside of the leakage information at the leakage and seepage location. Description of the Drawings

A sealing gasket 31 is arranged on the outside of the drainage connection pipe 3, and the sealing gasket 31 is fitted with the sealing groove 13. Four groups of symmetric connecting chutes 32 are arranged on the inner wall of the drainage connection pipe 3; the drainage connection pipe 3 is threadedly connected to the connecting threaded hole 14, and after the drainage connection pipe 3 is completely screwed into the connecting threaded hole 14, the sealing gasket 31 is completely fitted into the sealing groove 13.

[0031] Refer to Figure 2 and Figure 7, one end of the water leakage and drainage device 4 close to the drainage connection pipe 3 is provided with a plug-in connection pipe 42, and one end of the plug-in connection pipe 42 away from the water leakage and drainage device 4 is provided with a water receiving plate 422 in the shape of a semi-cylindrical body. The plug-in connection pipe 42 is inserted into the drainage connection pipe 3, and one end of the water receiving plate 422 is attached to the outer wall of the communication pipe 11; the water leakage and drainage device 4 is inserted into the drainage connection pipe 3 through the plug-in connection pipe 42, and the water leaked from the pipeline interface part 1 is received by the water receiving plate 422, and one end of the water receiving plate 422 extends out of the drainage connection pipe 3.

[0032] Refer to Figure 4 and Figure 8 , a connection plug 421 fitted with the connection sliding groove 32 is provided at the bottom of the plug-in connection pipe 42. A plurality of groups of diversion grooves 111 are provided on the inner wall of the pipeline interface part 1, and one end of each of the plurality of groups of diversion grooves 111 extends to the sealing clamping groove 13. A water leakage alarm 44 is connected to the inner wall of the water leakage and drainage device 4 close to the water receiving plate 422; the plug-in connection pipe 42 is inserted into the connection sliding groove 32 of the drainage connection pipe 3 through the connection plug 421, and the connection position of the drainage connection pipe 3 can be selected according to the placement position and vertical and horizontal states of the pipeline, so that the water receiving plate 422 and the water leakage alarm 44 are in the direction of the lowest point of the water leakage and drainage device 4. The water leaked from the indoor decorative water pipe 2 and the communication pipe 11 enters the pipeline interface part 1, and flows to the sealing clamping groove 13 through the diversion grooves 111 in the pipeline interface part 1. After the leaked water enters the water leakage and drainage device 4 through the drainage connection pipe 3, it flows to the lowest point of the water leakage and drainage device 4, that is, the water flow of the water leakage flows to the position of the water leakage alarm 44, and the water leakage alarm 44 can be an optoelectronic alarm or a wireless alarm, which is used to notify the outside of the water leakage information at the water leakage and seepage place, so as to facilitate the timely repair of the water leakage place.

[0033] Refer to Figure 8 and Figure 9 , the automatic drainage assembly 43 includes a lifting float 431 and a connecting ball valve 432. The connecting ball valve 432 is rotatably connected in the drainage port 41, and a switch connecting rod 433 is connected between the lifting float 431 and the connecting ball valve 432; the opening and closing of the drainage port 41 in the water leakage and drainage device 4 is controlled by the automatic drainage assembly 43. The drainage port 41 is sealed by the connecting ball valve 432, and the lifting float 431 drives the connecting ball valve 432 to rotate in the drainage port 41 through the switch connecting rod 433.

[0034] Refer to Figure 8 and Figure 9, a drain hole 4321 is provided at one end of the connecting ball valve 432 away from the switch connecting rod 433, and a plurality of water inlet holes 4322 are provided on one side of the connecting ball valve 432 away from the drain hole 4321. The plurality of water inlet holes 4322 are all communicated with the drain hole 4321; the water in the water leakage drainage device 4 enters the connecting ball valve 432 through the water inlet holes 4322, and the water in the connecting ball valve 432 can be discharged from the drain hole 4321. When the connecting ball valve 432 rotates to make the drain hole 4321 communicate with the drain port 41, at this time, the water leakage drainage device 4 can perform a drainage action. When the drain hole 4321 is completely away from the drain port 41, at this time, the water leakage drainage device 4 does not perform drainage work. When there is no water in the water leakage drainage device 4, at this time, the automatic drainage assembly 43 is in the initial position, and at this time, the water leakage drainage device 4 does not perform drainage work.

[0035] Refer to Figure 8 and Figure 9 , on the inner wall of one side of the water leakage drainage device 4 away from the water leakage alarm 44, a floating and limiting block 45 is connected, and the floating and limiting block 45 is arranged on the arc with the lifting floating ball 431 centered on the connecting ball valve 432; the lifting floating ball 431 performs a lifting action under the buoyancy of water, and the lifting trajectory of the lifting floating ball 431 is to lift centered on the connecting ball valve 432. When the lifting floating ball 431 rises to the floating and limiting block 45, the height of the lifting floating ball 431 is limited by the floating and limiting block 45, so as to prevent the lifting height of the lifting floating ball 431 from being too high, resulting in the drain hole 4321 moving away from the drain port 41 during the rising process. When the water leakage drainage device 4 is completely drained, the lifting floating ball 431 naturally falls under gravity, and when the lifting floating ball 431 falls to the lowest point, at this time, the drain hole 4321 is completely away from the drain port 41.

[0036] The working process of this application is as follows: First, insert the indoor decorative water pipe 2 into the pipeline connector 1, and connect the indoor decorative water pipe 2 to the communicating pipe 11, and seal the interface with the conical silicone connecting sleeve 5. After the connection is completed, use a ring pressing pipe wrench to press and fix it, so that the sealing pressing ring 51 is fitted into the annular connecting groove 12, and connect the drain connecting pipe 3 to the connecting threaded hole 14 by threading. After the drain connecting pipe 3 is completely screwed into the connecting threaded hole 14, the sealing gasket 31 is completely fitted into the sealing groove 13. Then, select the connection position of the drain connecting pipe 3 according to the placement position and horizontal and vertical states of the pipeline, so that the water receiving plate 422 and the water leakage alarm 44 are in the direction of the lowest point of the water leakage drainage device 4, and insert the plug-in connecting pipe 42 into the connecting chute 32 of the drain connecting pipe 3 through the connecting plug 421; The water leaking from the indoor decoration water pipe 2 and the connecting pipe 11 enters the pipe interface 1 and flows through the diversion groove 111 in the pipe interface 1 to the sealing card slot 13. The water leaking from the pipe interface 1 is received by the water receiving plate 422. After the leaked water enters the water leakage drainage device 4 through the drainage connecting pipe 3, it flows to the lowest point of the water leakage drainage device 4, that is, the position where the leaked water flows to the water leakage alarm 44. The water leakage alarm 44 can be an optoelectronic alarm or a wireless alarm, which is used to notify the outside of the water leakage information at the water leakage and seepage points, facilitating timely repair of the water leakage point and avoiding secondary damage caused by concealed leakage. The opening and closing of the drain port 41 in the water leakage drainage device 4 is controlled by the automatic drainage component 43. The drain port 41 is sealed by the connecting ball valve 432, and the lifting float 431 drives the connecting ball valve 432 to rotate in the drain port 41 through the switch connecting rod 433. The water in the water leakage drainage device 4 enters the connecting ball valve 432 through the water inlet hole 4322, and the water in the connecting ball valve 432 can be discharged from the drain hole 4321. When the connecting ball valve 432 rotates to make the drain hole 4321 communicate with the drain port 41, the water leakage drainage device 4 can perform the drainage action at this time. When the drain hole 4321 is completely away from the drain port 41, the water leakage drainage device 4 does not perform the drainage work at this time. When there is no water in the water leakage drainage device 4, the automatic drainage component 43 is in the initial position at this time, and the water leakage drainage device 4 does not perform the drainage work at this time.
