Description

Technical Field

[0001] This utility model belongs to the field of water distribution valve technology, and specifically relates to a water distribution valve core seat that is easy to install. Background Technology

[0002] A water diverter valve is a valve used to switch the direction of water flow. It controls the water flow by changing the position of the valve core seat.

[0003] Currently, Chinese utility model patent CN211715829U discloses a water distribution valve core seat that is easy to install. Existing water distribution valves generally switch water flow from two different valve ports by rotating the valve core seat. However, this only switches the water flow and does not easily control the flow rate within the two different valve ports. Furthermore, the valve core seat is installed inside the water distribution valve and is inconvenient to disassemble, making it difficult to quickly repair or replace if damaged, thus reducing its practicality. Additionally, when the water distribution valve switches the flow between the two valve ports, if the flow stops, backflow can easily occur, causing water from the port with the higher flow rate to flow into the port with the lower flow rate, thus affecting the water distribution flow rate between the two valve ports. Utility Model Content

[0004] The purpose of this utility model is to provide a water distribution valve core seat that is easy to install. Its advantages are that it is easy to switch and control the water flow of two valve ports in different directions and that it has the function of preventing water flow from flowing back inside the valve core seat.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a water distribution valve core seat that is easy to install, comprising a valve housing, an inlet valve port fixedly connected to the bottom of the valve housing, a first water distribution valve port and a second water distribution valve port fixedly connected to both sides of the surface of the valve housing, a valve core seat connected to the inlet valve port being slidably connected inside the valve housing, a threaded shaft being rotatably connected to the top of the valve core seat, a movable cover being bolted to the top of the threaded shaft, a valve cover being installed on the top of the valve housing and threadedly sleeved with the threaded shaft, and a first water distribution hole and a second water distribution hole being opened on both sides of the valve core seat near the first water distribution valve port and the second water distribution valve port, respectively.

[0006] By employing the above technical solution, the first and second water distribution holes are adjusted by sliding the valve core seat up and down inside the valve housing. This not only diverts the water entering the valve housing to the first and second water distribution valve ports, but also controls the water flow rate, improving practicality. The valve cover is removed from the top of the valve housing, allowing the valve core seat to be pulled directly out. This facilitates the replacement and reinstallation of damaged valve core seats. The spring force pushes the conical plug to seal the conical grooves inside the first and second water distribution valve ports. When water enters, the conical plug opens the normal water flow. When the water flow stops, the conical grooves are quickly sealed to prevent backflow of water inside the valve core seat.

[0007] The present invention is further configured such that: a connecting groove is provided inside the first water distribution valve port and the second water distribution valve port; a sliding cylinder is slidably connected to one end of the connecting groove near the valve housing; a conical hole groove is provided inside the first water distribution valve port and the second water distribution valve port near the valve housing; a conical plug block that is slidably inserted into the conical hole groove is welded to one end of the sliding cylinder near the valve housing; and a spring that is fixedly connected to the inside of the connecting groove is welded to one side of the sliding cylinder away from the conical plug block.

[0008] Using the above technical solution, the conical block can be pushed to open the normal flow of water when water enters, and the conical groove can be quickly sealed when the water flow stops to prevent the water from flowing back into the valve core seat.

[0009] The present invention is further provided that the surface of the movable cover is provided with anti-slip texture.

[0010] By adopting the above technical solution, the surface friction is increased, which facilitates the rotation of the movable cover to drive the threaded shaft to engage with the valve cover thread.

[0011] The present invention is further configured such that: the valve cover is threadedly connected to the top of the valve body, and waterproof rings are bonded to the top of the valve body, the valve core seat, the threaded shaft, and the sliding cylinder.

[0012] By adopting the above technical solution, the valve cover can be removed from the top of the valve body, which facilitates the replacement and reinstallation of the valve core seat, improves the sealing between the valve core seat and the valve body inside the water distribution valve, and prevents water leakage.

[0013] The present invention is further configured such that: threaded grooves are provided on the surface of the water inlet valve port, the first water distribution valve port and the second water distribution valve port at the end away from the valve housing.

[0014] The above technical solution facilitates the connection of the inlet valve, the first branch valve, and the second branch valve to the water pipe via threaded grooves.

[0015] The present invention is further configured such that a sealing gasket is fixedly sleeved on the surface of the conical plug and slidably connected to the conical groove.

[0016] By adopting the above technical solution, the sealing performance of the conical plug inside the conical groove is improved, preventing water from seeping back into the valve body.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. By adjusting the first and second water distribution holes by sliding the valve core seat up and down inside the valve housing, the water entering the valve housing can be diverted to the first and second water distribution valve ports. Simultaneously, the water flow rate can be controlled, improving practicality.

[0019] 2. The valve cover can be removed from the top of the valve body, allowing the valve core seat to be pulled directly out of the valve body. This facilitates the replacement and reinstallation of any damaged valve core seat.

[0020] 3. By utilizing the spring force to push the conical plug to seal the conical grooves inside the first and second water distribution valve ports, the conical plug can be pushed to open the normal flow of water when water enters. When the water flow stops, it can quickly seal the inside of the conical grooves to prevent water from flowing back into the valve core seat. Attached Figure Description

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1:

[0027] refer to Figure 1 , Figure 2A water distribution valve core seat that is easy to install includes a valve body 1. A water inlet valve port 2 is fixedly connected to the bottom of the valve body 1. A first water distribution valve port 3 and a second water distribution valve port 4 are fixedly connected to both sides of the valve body 1, respectively. A valve core seat 8, connected to the water inlet valve port 2, is slidably connected inside the valve body 1. A threaded shaft 7 is rotatably connected to the top of the valve core seat 8. A movable cover 6 is bolted to the top of the threaded shaft 7. A valve cover 5, threadedly sleeved with the threaded shaft 7, is installed on the top of the valve body 1. A first water distribution hole 9 and a second water distribution hole 10 are respectively opened on both sides of the valve core seat 8 near the first water distribution valve port 3 and the second water distribution valve port 4. By moving the valve core seat 8 up and down inside the valve body 1 to adjust the first water distribution hole 9 and the second water distribution hole 10, the water entering the valve body 1 can be diverted to the first water distribution valve port 3 and the second water distribution valve port 4. Simultaneously, the water flow rate can be controlled, improving practicality. The valve cover 5 is removed from the top of the valve body 1, allowing the valve core seat 8 to be pulled directly out of the valve body 1. This facilitates the replacement and reinstallation of any damaged valve core seat 8.

[0028] refer to Figure 1 The surface of the movable cover 6 is textured with anti-slip patterns. This increases surface friction and facilitates the rotation of the movable cover 6 to drive the threaded shaft 7 to engage with the threaded valve cover 5.

[0029] refer to Figure 1 The inlet valve port 2, the first branch valve port 3, and the second branch valve port 4 all have threaded grooves 18 on their surfaces away from the valve body 1. This facilitates the threaded connection of the inlet valve port 2, the first branch valve port 3, and the second branch valve port 4 to the water pipe through the threaded grooves 18.

[0030] Brief description of operation: By rotating the movable cover 6, the threaded shaft 7 engages with the valve cover 5, causing the threaded shaft 7 to drive the valve core seat 8 to slide up and down inside the valve body 1, injecting water into the valve body 1 through the inlet valve port 2. When the valve core seat 8 moves upward, it connects the first water distribution hole 9 with the inside of the first water distribution valve port 3, allowing the water entering through the inlet valve port 2 to flow into the first water distribution valve port 3. When the valve core seat 8 moves downward, it connects the second water distribution hole 10 with the inside of the second water distribution valve port 4, allowing the water entering through the inlet valve port 2 to flow into the second water distribution valve port 4, thereby diverting the water source. At the same time, when the valve core seat 8 is moved to the middle of the valve body 1, the first water distribution hole 9 and the second water distribution hole 10 are connected to the first water distribution valve port 3 and the second water distribution valve port 4 respectively, so that the water flow can flow into the first water distribution valve port 3 and the second water distribution valve port 4 respectively. The flow rate of the water flow into the first water distribution valve port 3 and the second water distribution valve port 4 can be controlled by adjusting the valve core seat 8 to slide up and down.

[0031] Example 2:

[0032] refer to Figure 1 , Figure 2 , Figure 3 A water distribution valve core seat that is easy to install has connecting grooves 12 inside both the first water distribution valve port 3 and the second water distribution valve port 4. A sliding cylinder 14 is slidably connected to one end of the connecting groove 12 near the valve housing 1. A conical groove 11 is formed inside both the first water distribution valve port 3 and the second water distribution valve port 4 near the valve housing 1. A conical plug 15, which slidably inserts into the conical groove 11, is welded to one end of the sliding cylinder 14 near the valve housing 1. A spring 13, which is fixedly connected to the inside of the connecting groove 12, is welded to the side of the sliding cylinder 14 away from the conical plug 15. The spring force of the spring 13 pushes the conical plug 15 to seal the conical groove 11 inside the first water distribution valve port 3 and the second water distribution valve port 4. This allows the conical plug 15 to open the normal flow of water when water enters. When the water flow stops, the conical groove 11 is quickly sealed to prevent backflow of water inside the valve core seat.

[0033] refer to Figure 2 , Figure 3 The valve cover 5 is threaded to the top of the valve body 1. Waterproof rings 17 are bonded to the top of the valve body 1, the valve core seat 8, the threaded shaft 7, and the sliding cylinder 14. This allows the valve cover 5 to be removed from the top of the valve body 1, facilitating the replacement and reinstallation of the valve core seat 8, improving the sealing between the valve core seat and the valve body inside the water distribution valve, and preventing water leakage.

[0034] refer to Figure 3 A sealing gasket 16 is fixedly fitted onto the surface of the conical plug 15 and slidably connected to the conical groove 11. This improves the sealing performance of the conical plug 15 inside the conical groove 11 and prevents water from seeping back into the valve body 1.

[0035] Brief description of the usage process: After water flows into the first water distribution valve port 3 or the second water distribution valve port 4, the water flow generates water pressure after passing through the conical groove 11. This pressure pushes the conical block 15 to overcome the elastic force of the spring 13, causing the sliding cylinder 14 to slide back into the conical block 15. This connects the conical groove 11 with the connecting groove 12, allowing water to flow out normally. Simultaneously, when the water flow stops inside the inlet valve port 2, the conical block 15, lacking water pressure, will be re-locked inside the conical groove 11 by the rebound force of the spring 13, sealing the inside of the conical groove 11 and preventing water from flowing back into the valve body 1.

[0036] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
