Description

Technical Field

[0001] This invention relates to the field of water-saving valves, specifically to an automatic water-saving safety valve and its water-saving method. Background Technology

[0002] In existing applications of automatic water-saving safety valves, the connecting pipe and the delivery pipe are usually connected via flanges. However, the diameter of delivery pipes is not uniform in daily life. This leads to the need to prepare various connection components of different specifications during installation due to compatibility issues between the flange and the delivery / connecting pipe, increasing the complexity and cost of installation.

[0003] Meanwhile, traditional flange connections often require tools for tightening during assembly, making the process cumbersome. Furthermore, leaks can easily occur during connection, wasting water resources and potentially damaging equipment, thus affecting the system's normal operation. Additionally, disassembling the flange is also inconvenient, further reducing work efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic water-saving safety valve and a water-saving method thereof to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic water-saving safety valve, comprising an automatic water-saving safety valve body, a connecting pipe fixed at the bottom and one side of the automatic water-saving safety valve body, a flange fixed at one end of the connecting pipe, a conveying pipe provided at one end of the connecting pipe, a flange fixed at one end of the conveying pipe, the flange and the flange abutting together, a connecting plate inserted between the flange and the flange, and two plugs of different sizes detachably installed on both sides of the connecting plate, the two plugs being inserted into the connecting pipe and the conveying pipe respectively; Multiple screws are fixed on both sides of the connecting plate. The two sets of screws pass through the bolt holes of flange one and flange surface, respectively. The surface of the screws is movably inserted with a stop block, which prevents the screw from being pulled out of the bolt hole. Both flange 1 and one side of flange are fitted with push rings. When the push ring is pushed into the connecting plate, it pushes the stop block into the screw, thus removing the limit between the screw and the bolt hole.

[0006] Preferably, the connecting plate has an annular plate structure, and both sides of the connecting plate have an assembly groove at the inner ring opening. The assembly groove is an annular groove. The plug tube is a "T"-shaped round tube. One end of the plug tube is inserted into the assembly groove. The surface of the plug tube has a recessed groove, which is an annular groove. Both the recessed groove and the assembly groove have multiple through holes, and the same set of bolts are inserted into the two sets of through holes.

[0007] Preferably, the surface of the assembly groove is fixed with rubber support rings, the sum of the thicknesses of the two rubber support rings is greater than the distance between the two assembly grooves, and the two rubber support rings are held between the two plug tubes and undergo elastic deformation.

[0008] Preferably, the connecting plate has an insert groove on both sides. The insert groove is annular and a rubber sealing gasket is fixed inside the insert groove. The rubber sealing gasket has an annular plate structure and the thickness of the rubber sealing gasket is greater than the depth of the insert groove.

[0009] Preferably, the screw has a mounting groove on its surface, one end of the stop block is inserted into the mounting groove, an elastic component is provided between one end of the stop block and the mounting groove, and the other end of the stop block has an inclined surface facing away from the connecting plate.

[0010] Preferably, the elastic component includes a rubber traction block and a support spring, both of which are fixed between the stop block and the mounting groove, with the support spring sleeved on the outside of the rubber traction block.

[0011] Preferably, both the flange and flange one have threaded grooves on their outer ring surfaces, and the inner ring surface of the threaded grooves has external threads. The push ring is an L-shaped circular plate with an internal thread on one end of its inner ring surface. The internal thread and the external thread are connected in a mating manner, and the inner ring surface of the other end of the push ring contacts the screw.

[0012] Preferably, the outer ring surface of the push ring is provided with a reserved groove, the reserved groove is an annular groove, a limit ring is fixed on the side wall of the screw groove, the limit ring is a circular plate with an "L" shaped cross section, one end of the limit ring is inserted into the reserved groove, and the surface of the push ring is provided with multiple picking grooves.

[0013] A water-saving method for an automatic water-saving safety valve includes the following steps: The automatic water-saving safety valve consists of a valve body, valve disc, spring, adjusting mechanism, and sealing components. When the system pressure exceeds the preset set value, the medium pressure overcomes the spring preload and pushes the valve disc to open, thus releasing excess medium for pressure relief protection. When the pressure drops below the reseating pressure, the spring force causes the valve disc to reset and close. At the same time, the flow control is optimized through diversion lever adjustment, air-water mixing pressurization, or flow limiting device technology, ensuring safety while reducing water waste. A connecting plate is installed between flange one and flange one. The plugs installed on both sides of the connecting plate are inserted into the connecting pipe and the delivery pipe, respectively. After the two sets of screws pass through the two sets of bolt holes, the stop block is placed on the outside of the bolt holes, so as to achieve quick connection between flange one and flange one, while preventing the screws from falling out of the bolt holes.

[0014] Compared with the prior art, the beneficial effects of the present invention are: The automatic water-saving safety valve and its water-saving method proposed in this invention can adapt to various pipe diameters of conveying pipes and connecting pipes by setting detachable plugs of different sizes on both sides of the connecting plate, thereby reducing installation costs and complexity. Automatic anti-detachment locking during flange splicing is achieved using screws, blocks, and elastic components, enabling tool-free quick connection, ensuring sealing, and effectively preventing water leakage to achieve water saving. The push ring, threaded groove, and limit ring structures allow for quick flange disassembly and prevent the push ring from falling off, thus improving the convenience and efficiency of installation and disassembly, and enhancing the practicality and reliability of the automatic water-saving safety valve.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1, please refer to Figures 1-9 This invention provides a technical solution: an automatic water-saving safety valve, comprising an automatic water-saving safety valve body 1, with a connecting pipe 101 fixed to the bottom and one side of the automatic water-saving safety valve body 1, a flange 102 fixed to one end of the connecting pipe 101, a conveying pipe 2 provided to one end of the connecting pipe 101, and a flange 201 fixed to one end of the conveying pipe 2. The flange 201 and the flange 102 abut together, and a connecting plate 3 is inserted between the flange 102 and the flange 201. Two plug tubes 302 of different sizes are detachably installed on both sides of the connecting plate 3, and the two plug tubes 302 are respectively inserted into the connecting pipe 101 and the conveying pipe 2. The connecting plate 3 has an annular plate structure, and an assembly groove 301 is opened at the inner ring opening on both sides of the connecting plate 3. The assembly groove 301 is an annular groove, and the plug tubes 302 are T-shaped. The plug tube 302 is inserted into the assembly groove 301 at one end. The surface of the plug tube 302 is provided with a recessed groove 308, which is an annular groove. Both the recessed groove 308 and the assembly groove 301 are provided with multiple through holes 303. The same set of bolts 304 are inserted into the two sets of through holes 303. The surface of the assembly groove 301 is fixed with rubber support rings 305. The sum of the thicknesses of the two rubber support rings 305 is greater than the distance between the two assembly grooves 301. The two rubber support rings 305 are sandwiched between the two plug tubes 302 and undergo elastic deformation. Both sides of the connecting plate 3 are provided with embedding grooves 306, which are annular grooves. The interior of the embedding groove 306 is fixed with a rubber sealing gasket 307, which is an annular plate structure. The thickness of the rubber sealing gasket 307 is greater than the depth of the embedding groove 306.

[0019] The reason for reserving the assembly grooves 301 on both sides of the connecting plate 3 is to install the plugs 302 of different sizes that match the inner ring of the conveying pipe 2 and the connecting pipe 101. Because the diameter of the conveying pipe 2 is not the same in life, several models of plugs 302 are prepared during production to adapt to different pipe diameters. After pushing the two plugs 302 into the assembly grooves 301 on both sides of the connecting plate 3, the bolts 304 are passed through the connecting plate 3 and the plugs 302 and then locked. The bolts 304 are in the grooves 308 of the two plugs 302. This ensures that the connecting plate 3 is clamped between the flange 102 and the flange 201. The addition of the rubber sealing gasket 307 ensures the sealing of the connecting plate 3 after it is installed between the flange 102 and the flange 201. The two plugs 302 connect the connecting pipe 101 and the flange 201 and form a transverse socket structure between the flange 102 and the flange 201.

[0020] To achieve automatic anti-detachment locking during the splicing of flange 102 and flange 201, the following was proposed: Multiple screws 4 are fixed on both sides of the connecting plate 3. The two sets of screws 4 pass through the bolt holes on the surfaces of flange 102 and flange 201, respectively. A stop block 402 is movably inserted into the surface of the screw 4 to prevent the screw 4 from being pulled out of the bolt hole. An installation groove 401 is opened on the surface of the screw 4. One end of the stop block 402 is inserted into the installation groove 401. An elastic component is provided between one end of the stop block 402 and the installation groove 401. The other end of the stop block 402 is provided with a bevel, which faces away from the connecting plate 3. The elastic component includes a rubber traction block 403 and a support spring 404. Both the rubber traction block 403 and the support spring 404 are fixed between the stop block 402 and the installation groove 401, and the support spring 404 is sleeved on the outside of the rubber traction block 403.

[0021] After placing the connecting plate 3 between flange 102 and flange 201, flange 102 and flange 201 are pushed in until the two sets of screws 4 pass through the bolt holes on the surfaces of flange 102 and flange 201 respectively. During the pushing process, the stop block 402, which is compressed by the rubber traction block 403 and the support spring 404 inside the mounting groove 401, rebounds and blocks the outside of the bolt holes, preventing the screws 4 from falling out of the bolt holes. This completes the tool-free quick connection of flange 102 and flange 201, ensuring a sealed connection between flange 102 and flange 201, preventing water leakage, and thus further achieving water conservation.

[0022] To achieve rapid separation of flange 102 and flange 201, the following was proposed: Both flange 102 and flange 201 have a push ring 6 threaded onto one side. When the push ring 6 is pushed into the connecting plate 3, the push block 402 retracts into the screw 4, removing the limit between the screw 4 and the bolt hole. Both flange 201 and flange 102 have a threaded groove 5 on their outer ring surface. The inner ring surface of the threaded groove 5 has an external thread. The push ring 6 is an L-shaped circular plate. One end of the push ring 6 has an internal thread on its inner ring surface. The internal thread and the external thread are connected. The other end of the push ring 6 has an inner ring surface that contacts the screw 4. The outer ring surface of the push ring 6 has a reserved groove 601. The reserved groove 601 is an annular groove. A limit ring 501 is fixed on the side wall of the threaded groove 5. The limit ring 501 is an L-shaped circular plate. One end of the limit ring 501 is inserted into the reserved groove 601. The surface of the push ring 6 has multiple slots 602.

[0023] When it is necessary to remove flange 201 and flange 102, use your fingers to pry open the prying groove 602 and rotate the push ring 6 to push it into the bolt groove 5. The inner ring of the push ring 6 pushes the stop block 402 into the mounting groove 401. At this time, the locking between the screw 4 and the bolt hole is removed, and flange 102 and flange 201 can be separated. The addition of the limit ring 501 prevents the push ring 6 from falling off the end of flange 102.

[0024] How to use an automatic water-saving safety valve: Based on the inner ring dimensions of the conveying pipe 2 and the connecting pipe 101, two matching plug tubes 302 are selected from a variety of manufactured plug tubes 302 models for later use. The two selected plug tubes 302 are then pushed into the assembly grooves 301 on both sides of the connecting plate 3, with one end of each plug tube 302 inserted into the groove. At this point, the rubber support ring 305 is clamped between the two plug tubes 302 and undergoes elastic deformation. Next, the bolts 304 are passed through the connecting plate 3, the countersunk grooves 308 on the surface of the plug tubes 302, and the corresponding through holes 303 on the assembly grooves 301, and then tightened, completing the installation of the plug tubes 302 on the connecting plate 3. Connecting plate 3 positioning and initial flange advancement: The connecting plate 3 with the plug tubes 302 installed is placed between flange 102 and flange 201, ensuring that the bolts 4 on both sides of the connecting plate 3 are aligned with the bolt holes on the surfaces of flange 102 and flange 201, respectively. Then, flanges 102 and 201 are pushed towards the connecting plate 3. During the pushing process, the inclined surface of the stop block 402 is squeezed by the edge of the bolt hole and is pushed into the inner side of the mounting groove 401. At the same time, the compressed rubber traction block 403 and the support spring 404 deform. After the two sets of screws 4 have completely passed through the bolt holes on the surfaces of flanges 102 and 201, the compressed rubber traction block 403 and the support spring 404 rebound, pushing the stop block 402 to rebound and block the outside of the bolt hole, preventing the screws 4 from falling out of the bolt hole. At this time, the tool-free quick connection of flanges 102 and 201 is completed. Moreover, since the thickness of the rubber sealing gasket 307 is greater than the depth of the mounting groove 306, the sealing performance of the connecting plate 3 after it is installed between flanges 102 and 201 is ensured, preventing water leakage and achieving water saving.

[0025] When it is necessary to remove flange 201 and flange 102, place your finger in the picking groove 602 on the surface of the push ring 6 and rotate the push ring 6 to push it into the bolt groove 5. As the inner ring of the push ring 6 pushes the stop block 402, the stop block 402 retracts into the mounting groove 401, thereby removing the restriction between the screw 4 and the bolt hole. At this time, flange 102 and flange 201 can be separated. At the same time, the limiting ring 501 prevents the push ring 6 from falling off the end of flange 102.

[0026] Example 2, based on Example 1, proposes a water-saving method for an automatic water-saving safety valve, comprising the following steps: The automatic water-saving safety valve body 1 consists of a valve body, valve disc, spring, adjustment mechanism, and sealing components. When the system pressure exceeds the preset set value, the medium pressure overcomes the spring preload and pushes the valve disc to open, thus achieving pressure relief protection by discharging excess medium. When the pressure drops below the reseating pressure, the spring force causes the valve disc to reset and close. At the same time, the flow control is optimized through diversion lever adjustment, air-water mixing pressurization, or flow limiting device technology, thereby reducing water waste while ensuring safety. A connecting plate 3 is installed between flange 201 and flange 102. The plugs 302 installed on both sides of the connecting plate 3 are inserted into the connecting pipe 101 and the conveying pipe 2 respectively. After the two sets of screws 4 pass through the two sets of bolt holes, the stop block 402 blocks the outside of the bolt holes, so as to achieve quick connection between flange 102 and flange 201 while preventing the screws 4 from falling out of the bolt holes.
