Description

Technical Field

[0001] This utility model belongs to the field of valve control technology, specifically relating to an integrated four-way pipe valve. Background Technology

[0002] Pipe valves combine the functions of connectors, plugs, and shut-off valves in a water supply system. They can function as plugs for water pressure testing (requiring no removal after concealment), as pipe connectors for connecting to faucets or other water-using equipment, and as automatic shut-off valves for easy replacement or disassembly of easily damaged parts (such as faucets and water purifiers). Conventional valve cores are ball-shaped with through holes. However, the fit between the outer surface of the ball and the inner wall of the valve body needs to be precise. Because it's difficult to guarantee a perfect 360-degree fit between the ball and the inner wall of the valve body during manufacturing, long-term use can lead to valve core sealing failure. Furthermore, the ball surface of the valve core is difficult to manufacture, making it hard to guarantee a perfect fit between the ball and the inner wall of the valve body, often resulting in an interference fit. This inevitably accelerates wear, and after a certain number of uses, it will affect the sealing performance. After repeated use, leakage is likely to occur at the mating surface between the ball and the inner wall of the valve body.

[0003] The butterfly valve is controlled by a sealing plate. However, it is difficult to guarantee the sealing plate's fit with the inner wall of the valve body within a 360-degree range, which may lead to water leakage during later use.

[0004] Therefore, how to provide an integrated four-way valve is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the present invention provides an integrated four-way pipe valve with long service life, good sealing performance, simple ball core construction process, low cost, and easy mass production and use.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an integrated four-way valve, comprising:

[0007] The pipe body has two valve bodies connected and communicating on opposite side walls. The inner wall of the valve body near the pipe body has a cylindrical surface with a flow port communicating with the pipe body. The valve body away from the pipe body has a pipe connector fixedly provided on the side communicating with the pipe body.

[0008] The valve core is a side-mounted U-shaped structure. The valve core is rotatably connected to the inner side of the valve body. The valve core is provided with an arc-shaped plate frame. An arc-shaped sealing plate is detachably connected to the arc-shaped plate frame. The arc-shaped sealing plate is dynamically and slidably connected to the cylindrical surface and can seal the flow port.

[0009] The beneficial effects of this utility model are as follows: The two valve body parts and one pipe body part of this product are combined at both ends to form a four-way pipe valve. The valve core structure used in this product is different from the baffle of traditional ball valves or butterfly valves. Instead, it is a side-mounted U-shaped structure. The valve core is provided with an arc-shaped plate frame. An arc-shaped sealing plate for sealing the flow port is detachably connected to the arc-shaped plate frame. The connection state between the pipe body part and the valve body part is changed by relying on the arc-shaped sealing plate. The arc-shaped sealing plate is simple to manufacture. It is only necessary to ensure that the area around the flow port is sealed. It is convenient to use.

[0010] Preferably, the bottom side plate corresponding to the valve core has an arc-shaped structure, and the bottom of the bottom side plate corresponding to the valve core has a axial protrusion. The inner bottom wall of the valve body has a recessed groove, and the recessed groove has a U-shaped retainer for positioning the axial protrusion. The top of the top side plate of the valve core is detachably connected to a sealing shaft platform. The sealing shaft platform is dynamically and rotatably connected to the top sleeve of the valve body. The top of the sealing shaft platform has an outer square head that is easy to twist, and the outer square head is located above the valve body.

[0011] The resulting technical effects are: the bottom side plate is arc-shaped, which on the one hand can balance the load on the arc-shaped frame, and on the other hand can improve the structural strength of the component and enhance its impact resistance. The top of the valve core and the mounting point of the valve body are sealed to prevent water leakage from the top of the valve body. The U-shaped retainer ensures the fixed-axis rotation position of the valve core, and the outer square head makes it easy for the operator to change the valve opening.

[0012] Preferably, the two ends of the pipe joint and the pipe body are used to connect to external water pipes or hoses.

[0013] The resulting technical effect is that, in practical use, both ends of the pipe joint and the pipe body can be connected to external water hoses or water pipes to achieve multi-channel adjustment and control.

[0014] Preferably, the arc-shaped plate frame is provided with multiple locking holes, the concave side of the arc-shaped sealing plate is provided with a buckle that matches the locking holes, and a sealing frame is detachably connected to the periphery of the arc-shaped sealing plate, the sealing frame being slidably connected to the cylindrical surface.

[0015] The resulting technical effect is that the buckle on the concave side of the arc-shaped sealing plate can be detachably connected to the locking hole, thereby realizing the mounting of the arc-shaped sealing plate and the arc-shaped plate frame. The sealing frame around the arc-shaped sealing plate can ensure the water sealing effect of the valve core and prevent water leakage from the periphery of the arc-shaped sealing plate.

[0016] Preferably, the sealing frame is a rubber frame.

[0017] The resulting technical effect is that the rubber frame can adapt to deformation and has strong self-adaptation capability. It should be noted that the sealing of the flow port is achieved by using an arc-shaped sealing plate and a sealing frame to form an adhesive layer on the cylindrical surface around the flow port. The main body is blocked by the arc-shaped sealing plate, resulting in a good sealing effect. It does not require complicated manufacturing processes and has a simple manufacturing cost.

[0022] 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.

[0023] See appendix to this utility model Figures 1 to 3 According to an embodiment of the present invention, an integrated four-way valve includes:

[0024] The pipe body 1 has two valve body parts 2 connected and connected on opposite side walls. The overall structure is a cross-shaped layout. The inner wall of the valve body part 2 near the pipe body part 1 has a cylindrical surface 21. The cylindrical surface 21 has a flow port 22 that connects to the pipe body part 1. The valve body part 2 away from the pipe body part 1 has an integrally heat-sealed pipe joint 23 that is not easy to leak. The pipe body and the pipe joint can be made of rigid plastic.

[0025] Valve core 3 is a side-mounted U-shaped structure. Valve core 3 is rotatably connected to the inner side of valve body 2. Valve core 3 is provided with an arc-shaped plate frame 31. An arc-shaped sealing plate 32 is detachably connected to the arc-shaped plate frame 31. The arc-shaped sealing plate 32 is dynamically and slidably connected to the cylindrical surface 21 and can seal the flow port 22.

[0026] In practice, the area of ​​the arc-shaped sealing plate only needs to be slightly larger than the area of ​​the flow port.

[0027] In other embodiments, the bottom side plate corresponding to the valve core 3 has an arc-shaped structure. The bottom of the bottom side plate corresponding to the valve core 3 is provided with a shaft protrusion 33. The inner bottom wall of the valve body 2 is provided with a groove 24. The groove 24 is provided with a U-shaped bracket 35 for positioning the shaft protrusion 33. A sealing shaft platform 36 is detachably connected to the top of the top side plate of the valve core 3. The sealing shaft platform 36 is dynamically and rotatably connected to the top sleeve of the valve body 2 to prevent water leakage from the top of the valve body. The top of the sealing shaft platform 36 is provided with an outer square head 34 that is easy to turn, so that the operator can turn the valve core and adjust the valve opening. The outer square head 34 is located above the valve body 2.

[0028] In other embodiments, the two ends of the pipe connector 23 and the pipe body 1 are used to connect to external water pipes or hoses. Depending on actual needs, the two ends of the pipe body are provided with annular protrusions to facilitate the connection of external water pipes or hoses.

[0029] In some other embodiments, the arc-shaped plate frame 31 is provided with two locking holes, and the concave side of the arc-shaped sealing plate 32 is provided with two buckles that match the locking holes. The periphery of the arc-shaped sealing plate 32 is detachably connected to a sealing frame 37. It can be understood that the arc-shaped sealing plate can be embedded in the sealing frame, and when the arc-shaped sealing plate is fastened, the sealing frame can be pressed and fixed against the arc-shaped plate frame. The sealing frame 37 is dynamically and slidably connected to the cylindrical surface 21, which is the basis for ensuring the safety of the valve core sealing the flow port.

[0030] Specifically, the sealing frame 37 is a rubber frame with a certain deformation range, which can adapt to deformation.

[0031] Specific control process:

[0032] When the arc-shaped sealing plate of the valve core corresponds to the flow port, it can block the water flow between the pipe body and the valve body. The sealing frame around the arc-shaped sealing plate provides another layer of sealing protection. At this time, the corresponding flow port is blocked. When it is necessary for the pipe body and the corresponding valve body to be connected, the valve core on the corresponding valve body is turned to rotate the valve core to the side of the flow port. At this time, there is no arc-shaped sealing plate blocking the flow port, and the water path is connected.

[0033] The apparatus and methods disclosed in the embodiments are described in a relatively simple manner since they correspond to the methods disclosed in the embodiments. For relevant details, please refer to the description in the method section.

[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
