Description

Technical Field

[0001] This utility model relates to the field of pressure regulating valve technology, and in particular to a pressure regulating valve for micro-spraying with an independent switch. Background Technology

[0002] Pressure regulating valves are valves specifically designed to regulate pressure in fluid systems. Their main function is to ensure that the fluid maintains a stable pressure during the supply process to meet the system's operational requirements. By precisely controlling the fluid pressure, these valves help achieve efficient and stable system operation.

[0003] In a micro-sprinkler irrigation system, a pressure regulating valve is connected to the outlet end of the system to adjust and maintain the water flow rate. However, there is no corresponding independent control switch at each outlet end. Before use, the user needs to adjust the valve opening to change the system pressure according to the requirements to ensure that the system pressure reaches the required value. If the valve is directly closed to cut off the flow, the valve opening and closing needs to be readjusted and the system pressure needs to be checked the next time it is used, which is extremely inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a pressure regulating valve for micro-spraying with an independent switch.

[0005] An embodiment of this utility model provides a pressure regulating valve for micro-spraying with an independent switch, comprising:

[0006] The valve body has an inlet pipe and an outlet pipe fixedly installed on both sides. An opening / closing assembly and a filtering assembly are installed on the inlet pipe. The opening / closing assembly includes a connecting block fixedly connected to the side wall of the inlet pipe. A sliding cavity is formed on the connecting block. A threaded rod is rotatably connected to the inner wall of the sliding cavity. A lifting block is slidably connected within the sliding cavity. The threaded rod threaded through the lifting block. A sealing plate is fixedly connected to the lower end face of the lifting block. The sealing plate slidably passes through the connecting block and the inlet pipe. A sealing groove is formed on the inner wall of the inlet pipe, and the sealing groove matches the sealing plate. A rotating cavity is formed on the connecting block. A first bevel gear and a second bevel gear are rotatably connected to the inner wall of the rotating cavity. The first and second bevel gears mesh with each other. The first bevel gear is fixedly connected to the threaded rod. A rotating rod rotatably passes through the connecting block, and the rotating rod and the second bevel gear are fixedly connected.

[0007] Furthermore, a connecting frame slides through the water inlet pipe, a filter screen is fixedly connected to the inner wall of the connecting frame, and multiple bolts slide through the connecting frame, all of which are threaded onto the water inlet pipe.

[0008] Furthermore, both the inlet pipe and the outlet pipe are fixedly connected to a fixed flange at the end furthest from the valve body.

[0009] Furthermore, both the connecting frame and the side wall of the lifting block are provided with a sealing gasket layer, and the sealing gasket layer is made of rubber.

[0010] Furthermore, a handle is fixedly connected to the rotating rod, and a protective pad is provided on the handle.

[0011] Furthermore, a handle is fixedly connected to the connecting frame, and the handle is provided with anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By connecting the inlet and outlet pipes to designated locations, when it is necessary to block the water flow, the user rotates the handle to lower the sealing plate into the sealing groove, thereby blocking the water in the inlet pipe. This allows for independent control of the on / off state of a single sprinkler head in the micro-sprinkler irrigation system, making it convenient to use.

[0014] 2. The filter screen located on the connecting frame can filter the water entering the inlet pipe, ensuring the normal operation of the valve body and extending its service life. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a pressure regulating valve for micro-spraying with an independent switch, comprising:

[0021] Valve body 1, which is existing technology, mainly consists of valve body, valve core, actuator, and pressure measuring element. Its working principle is to change the flow area between valve core and valve seat by operating the actuator, thereby achieving precise control of fluid medium pressure. It will not be elaborated here. Water inlet pipe 2 and water outlet pipe are fixedly installed on both sides of valve body 1. Fixed flange 14 is fixedly connected to the end of water inlet pipe 2 and water outlet pipe away from valve body 1, so that users can connect water inlet pipe 2 and water outlet pipe to the designated water supply pipeline. Opening and closing assembly and water filtering assembly are installed on water inlet pipe 2. Opening and closing assembly includes connecting block 3 fixedly connected to the side wall of water inlet pipe 2. A sliding cavity 4 is opened on the connecting block 3. A threaded rod 5 is rotatably connected to the inner wall of sliding cavity 4. A lifting block 6 is slidably connected in sliding cavity 4. The threaded rod 5 is threaded through lifting block 6. A sealing plate 7 is fixedly connected to the lower end face of lifting block 6.

[0022] The sealing plate 7 slides through the connecting block 3 and the water inlet pipe 2. The inner wall of the water inlet pipe 2 has a sealing groove that matches the sealing plate 7. The connecting block 3 has a rotating cavity 8. The inner wall of the rotating cavity 8 is rotatably connected to a first bevel gear 9 and a second bevel gear 10. The first bevel gear 9 and the second bevel gear 10 mesh with each other. The first bevel gear 9 is fixedly connected to the threaded rod 5. A rotating rod rotatably passes through the connecting block 3. The rotating rod is fixedly connected to the second bevel gear 10. A handle 15 is fixedly connected to the rotating rod. The handle 15 is provided with a protective pad to facilitate the user's rotation of the rotating rod and improve the portability of the device.

[0023] A connecting frame 11 slides through the water inlet pipe 2. A filter screen 12 is fixedly connected to the inner wall of the connecting frame 11. Multiple bolts 13 slide through the connecting frame 11 and are threaded onto the water inlet pipe 2. A handle 16 is fixedly connected to the connecting frame 11. The handle 16 has anti-slip textures to facilitate the user to pull the connecting frame 11, improving the portability of the device. Both the connecting frame 11 and the lifting block 6 have sealing gaskets on their side walls. The sealing gaskets are made of rubber, which improves the sealing between the connecting frame 11 and the water outlet pipe, and between the lifting block 6 and the water outlet pipe, preventing water leakage.

[0024] The detailed working process of this utility model is as follows:

[0025] First, place the device in the designated location, then connect the inlet pipe 2 and the outlet pipe to the designated location. When it is necessary to block the water flow, the user rotates the handle 15. Under the transmission of the first bevel gear 9 and the second bevel gear 10, the threaded rod 5 rotates, and the lifting block 6 slides in the sliding cavity 4, which allows the sealing plate 7 to descend and move into the sealing groove on the inlet pipe 2, thereby blocking the water in the inlet pipe 2. This enables independent control of the on / off of a single sprinkler head in the micro-sprinkler irrigation system, making it easy to use. The filter screen 12 located on the connecting frame 11 can filter the water entering the inlet pipe 2, ensuring the normal operation of the valve body 1 and extending its service life. When it is necessary to clean the filter screen 12, the user unscrews the bolt 13 and then uses the handle 16 to pull out the connecting frame 11, making it easy for the user to install and remove the filter screen 12 on the connecting frame 11, thus improving the portability of the device.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
