Description

Technical Field

[0001] This utility model relates to the field of water collector technology, specifically a forged shut-off valve type water collector. Background Technology

[0002] A manifold is a device used in underfloor heating systems to connect the main heating supply pipes and return pipes. It consists of two parts: a manifold and a collector. The manifold is a water distribution device used to connect the supply pipes of each heating pipe in the water system, while the collector is a water collection device used to connect the return pipes of each heating pipe in the water system.

[0003] For example, an existing patent (publication number: CN216591888U) discloses a manifold that uses the external thread of the main water supply pipe connected to the main water supply pipe to cooperate with the internal thread of the filter to complete the disassembly and assembly of the filter on the manifold. The filter element can be disassembled and replaced, and the filter screen can be cleaned, so as to realize the function of easy cleaning of the filter, extend the life of the entire heating system and the manifold, and meet the practical effect of the entire device.

[0004] However, the above-designed manifold still has some drawbacks in actual use: although the manifold can connect the pipeline using a threaded structure to facilitate installation and disassembly, the sealing performance cannot be guaranteed. Existing pipe sealing usually uses rubber sealing rings, but after long-term use and corrosion, they are prone to aging and leakage.

[0005] To address this issue, we designed a forged shut-off valve type manifold. Utility Model Content

[0006] The purpose of this utility model is to provide a forged shut-off valve type water manifold to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a forged shut-off valve type water manifold, including a water collection tank with multiple shut-off valve bodies at the bottom. A connector is provided at the bottom end of each shut-off valve body, and a fixed cylinder is provided at the bottom of the connector. An air bladder ring is provided in the inner ring of the fixed cylinder. An air collection box is provided on one side of the connector, and a U-shaped tube is provided at the bottom of one side of the air collection box. A one-way air inlet valve and a one-way air outlet valve are respectively provided on the U-shaped tube. The other end of the one-way air outlet valve passes through the fixed cylinder and extends into the air bladder ring. An inflation component for inflating the air bladder ring is also provided in the air collection box.

[0008] Furthermore, the inflation assembly includes a piston plate, which is slidably connected to the air collection box in a vertical direction. A vent hole communicating with the interior is opened on the top of one side of the air collection box. A sliding rod is provided at the center of the top of the piston plate in a vertical direction, and the top end of the sliding rod slides through the air collection box.

[0009] Furthermore, a pull block is fixedly installed at the top of the slide rod, and the diameter of the pull block is larger than the diameter of the slide rod.

[0010] Furthermore, a spring is fixedly installed on the top of the piston plate in the vertical direction, and the other end of the spring is disposed on the top wall inside the gas collecting box.

[0011] Furthermore, the number of springs is two, and the two springs are respectively installed at both ends between the piston plate and the top wall of the gas collecting box.

[0012] Furthermore, a telescopic rod is provided vertically between the piston plate and the top wall of the gas collecting box, and the spring is movably sleeved on the telescopic rod.

[0013] Furthermore, the bottom of the connector is provided with a threaded groove for threaded insertion into a connecting pipe with an external thread on its surface.

[0014] Furthermore, positioning plates are installed at both ends of the rear side of the water collection tank, and multiple bolts are threaded into the front side of the positioning plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by pushing and pulling the slide rod back and forth in the vertical direction, the slide rod can drive the piston plate to move vertically up and down in the air collection box. During this process, outside air can be drawn into the U-shaped pipe and the air collection box through the one-way air inlet valve, and then squeezed into the air bag ring by the piston plate, so that the air bag ring expands and tightly adheres to the connecting pipe, thus ensuring the sealing of the pipeline on the water distributor.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting a spring, when a person releases the sliding rod directly, the spring can drive the piston plate to move downward due to its own elasticity, which can save more effort when the person needs to push the piston plate downward. By setting a telescopic rod, the piston plate can only slide along the direction of the telescopic rod extension end, avoiding the problem of movement deviation. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a forged stop valve type water manifold, including a water collection tank 1 with multiple stop valve bodies 2 at the bottom, a connector 3 at the bottom end of the stop valve body 2, a fixed cylinder 4 at the bottom of the connector 3, an air bladder ring 5 in the inner ring of the fixed cylinder 4, an air collection box 6 on one side of the connector 3, a U-shaped tube 7 at the bottom of one side of the air collection box 6, a one-way air inlet valve 18 and a one-way air outlet valve 8 respectively on the U-shaped tube 7, the other end of the one-way air outlet valve 8 passes through the fixed cylinder 4 and extends into the air bladder ring 5, and an inflation component for inflating the air bladder ring 5 is also provided in the air collection box 6; The inflation assembly includes a piston plate 9, which is slidably connected to the air collection box 6 in a vertical direction. A vent hole 11 communicating with the interior is opened on the top of one side of the air collection box 6. A slide rod 10 is arranged vertically at the center of the top of the piston plate 9. The top of the slide rod 10 slides through the air collection box 6. A threaded groove 15 is opened at the bottom of the connector 3 for threaded insertion into a connecting pipe with an external thread on the surface.

[0021] In practice, the threaded connecting pipe is inserted into the threaded groove 15, and then the slide rod 10 is pushed and pulled back and forth in the vertical direction. The slide rod 10 drives the piston plate 9 to move vertically up and down in the air collection box 6. During this process, outside air can be drawn into the U-shaped pipe 7 and the air collection box 6 through the one-way air inlet valve 18, and then squeezed into the air bag ring 5 by the piston plate 9, so that the air bag ring 5 expands and tightly adheres to the connecting pipe, thus ensuring the sealing of the pipeline on the water manifold.

[0022] The manifold features a shut-off valve body 2, enabling precise flow control. The forged valve body 2 withstands long-term thermal expansion and contraction, reducing the risk of leakage. The manifold typically consists of a distributor and a collector, working together to distribute and recover fluids. The basic principle is that hot water from heat sources such as boilers and heat pumps first enters the main pipe of the distributor. Multiple branch interfaces are connected to the main pipe, each corresponding to a terminal. Hot water is evenly distributed to each branch through these interfaces. The hot water in each branch flows through the terminal equipment, exchanging heat with the indoor air and releasing heat, thus lowering the water temperature. The cooled water then flows back through pipes to the corresponding branch interface of the collector, ultimately converging into the main pipe of the collector and flowing back to the heat source for reheating, completing one cycle. Since the collection tank 1 is existing technology and not a problem addressed in the background of this specification, it will not be discussed further.

[0023] In addition, for the airbag ring 5, we prioritize the use of fluororubber material. Because fluororubber has high corrosion resistance and high temperature resistance, it can not only effectively delay the corrosion of the airbag ring 5, but also enable the airbag ring 5 to be used normally in high temperature environment, ensuring the sealing performance.

[0024] See Figure 1-4 A pull block 12 is fixedly installed at the top of the slide rod 10. The diameter of the pull block 12 is larger than the diameter of the slide rod 10. Pushing or pulling the pull block 12 can cause the pull block 12 to drive the slide rod 10 to move, which can better apply force when the person pushes or pulls the slide rod 10.

[0025] See Figure 1-4 A spring 13 is fixedly installed vertically on the top of the piston plate 9, and the other end of the spring 13 is set on the top wall inside the air collection box 6. When it is necessary to push the piston plate 9 downward, the person can simply release their hand, and the spring 13 will move the piston plate 9 downward due to its own elastic force, which makes it easier for the person to push the piston plate 9 downward.

[0026] See Figure 1-4 There are two springs 13, and the two springs 13 are respectively installed at both ends between the piston plate 9 and the top wall of the gas collecting box 6.

[0027] In practice, based on the above implementation, the setting of two springs 13 can ensure that the top two ends of the piston plate 9 are subjected to balanced forces, thereby avoiding the problem of the piston plate 9 tilting during movement.

[0028] See Figure 1-4 A telescopic rod 14 is also provided vertically between the piston plate 9 and the inner top wall of the air collection box 6, and a spring 13 is movably sleeved on the telescopic rod 14. By providing the telescopic rod 14, the piston plate 9 can only slide along the telescopic end of the telescopic rod 14, avoiding the problem of movement deviation.

[0029] See Figure 1-4 Positioning plates 16 are installed at both ends of the rear side of the water collection tank 1, and multiple bolts 17 are threaded into the front side of the positioning plates 16. This facilitates the fixing of the water collection tank 1 to a suitable position on the wall.

[0030] Working principle: Before use, all electrical appliances involved in the water distribution device need to be connected to an external power source, or a battery pack needs to be installed in an area outside the water collection tank 1 that does not obstruct other components. Then, the battery pack is connected to the electrical appliances through wiring. It is also necessary to avoid the wiring from getting tangled due to the movement of the components. Wiring needs to be buried and planned and organized to provide power to the electrical appliances, thereby ensuring their normal operation and switching. Since connecting the electrical appliances to an external power source or setting up a battery pack for power supply are existing technologies and are not problems that need to be solved in the background technology of this manual, they will not be explained in detail.

[0031] When using the water manifold device, if it is necessary to connect the pipeline, first insert the threaded connecting pipe into the threaded groove 15, and then push and pull the pull block 12 back and forth in the vertical direction. The pull block 12 drives the slide rod 10 and the piston plate 9 to move vertically up and down in the air collection box 6. During this process, outside air can be drawn into the U-shaped pipe 7 and the air collection box 6 through the one-way air inlet valve 18, and then squeezed into the air bag ring 5 by the piston plate 9, so that the air bag ring 5 expands and tightly adheres to the connecting pipe, thus ensuring the sealing of the pipeline on the water manifold.

[0032] During the above operation, when it is necessary to push the piston plate 9 downward, the person can simply let go, and the spring 13 will move the piston plate 9 downward due to its own elasticity. This makes it easier for the person to push the piston plate 9 downward. By setting the telescopic rod 14, the piston plate 9 can only slide along the direction of the telescopic rod 14, avoiding the problem of movement deviation.
