Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation valve technology, and in particular to a quick-installation three-way valve. Background Technology

[0002] A three-way valve is a commonly used pipeline connection element. It mainly controls and regulates fluids by changing the internal passage of the valve by controlling the movement of the valve core. It typically has one main inlet and two outlets, or one inlet and four outlets, and can bring together multiple pipelines to achieve fluid exchange between pipelines in different locations and directions, which is especially important in fields such as industry, agriculture and construction.

[0003] Chinese Patent Publication No. CN212718190U discloses a quick-installation threaded five-way valve, belonging to the field of fluid conversion valve technology. This quick-installation threaded five-way valve includes a main inlet pipe, an adapter, and a flow restrictor. One end of the main inlet pipe is threaded to the adapter. The outer surface of the adapter, away from the main inlet pipe, has an external thread. A main valve is located on the outer surface of the main inlet pipe near the pipe opening. A first flow pipe is fixedly connected to the outer surface of the main inlet pipe near the main valve. A second flow pipe is fixedly connected to the outer surface of the main inlet pipe away from the first flow pipe. A third flow pipe is fixedly connected to the outer surface of the main inlet pipe near the pipe opening. A fourth flow pipe is fixedly connected to the outer surface of the main inlet pipe away from the third flow pipe. This quick-installation threaded five-way valve, with its hexagonal nut, facilitates easy installation and disassembly at the valve body interface. The flow restrictor allows for convenient control of the flow rate within the pipeline.

[0004] The aforementioned patented technology, by setting a hexagonal nut, facilitates easy installation and disassembly at the valve body interface. By setting a flow limiting switch, it can easily control the flow rate in the pipeline. However, it is inconvenient to adjust the tightness of the seal and to accurately control the water flow. Utility Model Content

[0005] The main purpose of this utility model is to provide a quick-installation three-way valve, which can effectively solve the problems mentioned above. The patented technology uses a hexagonal nut to facilitate easy installation and disassembly at the valve body interface, and a flow-limiting switch to facilitate control of the flow rate in the pipeline. However, it is inconvenient to adjust the tightness of the seal and to accurately control the water flow.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A quick-installation three-way valve includes a three-way valve upper shell and a three-way valve lower shell that matches the upper shell. A water distribution plate is provided inside both the upper and lower shells. A three-way valve stem is provided through the inner sides of both the upper and lower shells. A motor is mounted on the upper end of the three-way valve stem on the upper side of the upper shell. The three-way valve stem and the upper shell are rotatably connected by an O-ring seal. The three-way valve stem is also engaged with the water distribution plate and can slide relative to it. A water distribution plate passage hole is provided at one end of the inner side of the water distribution plate, and a water distribution plate slide is provided in the middle of the passage hole. Two upper shell outlets are correspondingly provided on the inner side of the upper shell.

[0007] Preferably, the distance from the center point of the water passage hole of the water distribution plate to the center point of the three-way valve stem is equal to the distance from the center point of the water outlet of each upper shell to the center point of the three-way valve stem.

[0008] Preferably, a controller is installed on the upper end of the three-way valve housing outside the motor, and the controller is connected to the motor.

[0009] Preferably, an adjusting nut is provided at the lower end of the three-way valve stem.

[0010] Preferably, a sealing gasket is provided on the inner side of each of the two upper shell water outlets, and a water outlet connector is installed at the upper end of each upper shell water outlet. The upper shell and lower shell of the three-way valve are fixedly connected by several bolts, and the water outlet connector is directly cast and molded to connect with the corresponding upper shell water outlet.

[0011] Preferably, the lower shell of the three-way valve is cast with a lower shell protrusion that contacts the water distribution plate, providing a pre-tightening force for sealing the water outlet.

[0012] Preferably, the three-way valve stem, adjusting nut, lower shell protrusion, water distribution plate, upper shell outlet, sealing gasket, etc., together provide the pre-tightening force for sealing the outlet.

[0013] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a three-way valve stem, adjusting nut, lower shell protrusion, water distribution plate, upper shell outlet, and inner sealing gasket to jointly adjust the pressure between the water distribution plate and the upper shell of the three-way valve, thereby adjusting the tightness of the outlet sealing gasket. This can prevent leakage due to insufficient pressure, and also prevent excessive pressure from increasing the valve opening torque and causing the outlet sealing gasket to wear too quickly. This invention uses a controller and a three-way valve stem to drive the water distribution plate and its water passage holes to rotate together, so that the water passage holes of the water distribution plate are connected or closed with the corresponding water outlets on the upper shell. This allows for precise water flow and flow regulation at each water outlet joint. Furthermore, during the rotation of the water distribution plate's water passage holes, the contact area between the water outlet and the sealing gasket of the water outlet on the upper shell of the three-way valve is small, resulting in low and stable friction. Only a small torque is needed to open and close the valve. Attached Figure Description

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please see Figures 1-5 In this embodiment of the utility model, a quick-installation three-way valve includes a three-way valve upper shell 1 and a three-way valve lower shell 6 that matches the three-way valve upper shell 1. A water distribution plate 4 is provided inside both the three-way valve upper shell 1 and the three-way valve lower shell 6. A three-way valve stem 3 is provided through both the inner sides of the three-way valve upper shell 1 and the water distribution plate 4. A motor 2 is installed at the upper end of the three-way valve stem 3 on the upper side of the three-way valve upper shell 1. The three-way valve stem 3 and the three-way valve upper shell 1 are rotatably connected by an O-ring seal. The three-way valve stem 3 is engaged with the water distribution plate 4 and can slide relative to it. A water distribution plate water passage hole 10 is provided at one end of the inner side of the water distribution plate 4. A water distribution plate slide 11 is provided in the middle of the water distribution plate water passage hole 10. Two upper shell water outlets 12 are correspondingly provided on the inner side of the three-way valve upper shell 1.

[0018] The adjusting nut 9 is set at the position of the three-way valve stem 3 to adjust the pressure of the water distribution plate 4 and the outlet sealing gasket 5 of the upper shell 1 of the three-way valve, thereby adjusting the tightness of the outlet sealing gasket 5. This can prevent leakage due to insufficient pressure and prevent the outlet sealing gasket 5 from wearing out too quickly due to excessive pressure. A water distribution plate through hole 10 is provided at one end of the inner side of the water distribution plate 4. The water distribution plate through hole 10 is designed with a water distribution plate slide 11 inside, which provides a second pre-tightening force for water outlet sealing with the lower shell protrusion 7. The inner side of the upper shell 1 of the three-way valve is annular and has two upper shell outlets 12. Each upper shell outlet 12 has an outlet connector cast at the upper end.

[0019] For details, please refer to Figure 1 , Figure 2 and Figure 3 In this embodiment, the distance from the center point of the water passage hole 10 of the water distribution plate to the center point of the three-way valve stem 3 is equal to the distance from the center point of each upper shell outlet 12 to the center point of the three-way valve stem 3. Further reference Figure 1 and Figure 2 In this embodiment, a controller is installed on the upper end of the three-way valve upper shell 1 outside the motor 2, and the controller is connected to the motor. The controller can send commands to motor 2 to control its start and stop; Further reference Figure 1 and Figure 2 In this embodiment, an adjusting nut 9 is provided at the lower end of the three-way valve stem 3; Further reference Figure 1 , Figure 2 and Figure 3 In this embodiment, a sealing gasket 5 is provided on the inner side of each of the two upper shell outlets 12. An outlet connector is installed at the upper end of each upper shell outlet 12. The upper shell 1 of the three-way valve and the lower shell 6 of the three-way valve are fixedly connected by several bolts. The outlet connector is directly cast and molded to connect with the corresponding upper shell outlet 12. Further reference Figure 1 and Figure 2 In this embodiment, the lower shell 6 of the three-way valve is cast with a lower shell protrusion 7 that contacts the water distribution plate 4 to provide a pre-tightening force for sealing the water outlet; exist Figure 1 and Figure 2 In the middle, the lower end of the three-way valve lower shell 6 is cast with two types of inlet connectors: quick connector and internal thread connector. Connect the inlet connector to the external inlet pipe, and external water can enter the three-way valve lower shell 6 from the inlet connector and then flow out from the corresponding outlet connector. Further reference Figure 1 and Figure 2In this embodiment, the three-way valve stem 3 and the adjusting nut 9, the lower shell protrusion 7 and the water distribution plate, the upper shell outlet 12, the sealing gasket 5, etc., together provide the pre-tightening force for sealing the outlet.

[0020] When in use, the three-way valve stem 3 is rotatably connected to the three-way valve upper shell 1, and the three-way valve stem 3 is engaged with the water distribution plate 4. When the three-way valve stem 3 rotates, it will drive the water distribution plate 4 to rotate together, while the three-way valve upper shell 1 remains stationary. The distance from the center point of the water distribution plate through hole 10 to the center point of the three-way valve stem 3 is equal to the distance from the center point of each upper shell outlet 12 to the center point of the three-way valve stem 3. When the motor 2 drives the three-way valve stem 3 to rotate, the three-way valve stem 3 drives the water distribution plate 4 and the water distribution plate through hole 10 to rotate together. When the water distribution plate through hole 10 is connected to the corresponding upper shell outlet 12, the water in the lower shell 6 of the three-way valve can flow into the outlet connector, thereby accurately realizing the water flow of each outlet connector. In this process, the water passage hole 10 of the water distribution plate contacts and is pre-tightened with the sealing gasket of the outlet of the upper shell 1 of the three-way valve during rotation. Its contact surface is small, so the friction is small and stable. In contrast, the traditional ball valve adopts a spherical sealing structure, which has a larger contact surface and is prone to eccentricity. During the opening and closing process, the ball surface is always in contact with the sealing gasket, especially at the beginning of opening and closing, the friction is large, requiring a large torque and is not stable. This device uses an end face and plane sealing structure, which requires less torque to open and close the valve compared to a ball valve, and the sealing is reliable and easy to disassemble and maintain.

[0021] exist Figure 4 In the middle, the upper shell 1 and the lower shell 6 of the three-way valve are fixedly connected by several bolts, which enables the quick assembly of the three-way valve and the disassembly and maintenance of its parts; like Figure 4 As shown, when two more outlet connectors are added, the three-way valve can be transformed into a five-way valve, thus allowing for flexible arrangement of the number of outlets according to actual needs. In actual use, the number of upper shell outlets 12 on the inner side of the upper shell 1 of the three-way valve can be selectively increased according to actual needs, and each newly added upper shell outlet 12 must be equipped with a corresponding sealing gasket and outlet connector to form a multi-way valve.

[0022] exist Figure 5 In the middle, the water distribution plate 4 is newly added with two corresponding water outlets with the same center distance, which can change the "three-way" valve from one inlet and one outlet to one inlet and two outlets.

[0023] The external controller added to motor 2 in this solution can be a controller that is matched with motor 2 in the prior art. It can control the opening and closing of motor 2. Since it is a very mature product in the prior art, it will not be described in detail in this application.

[0024] It should be noted that the specific installation method, circuit connection method and control method of the motor 2 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
