Description

Technical Field

[0001] This utility model relates to a fast-switching high-pressure solenoid valve. Background Technology

[0002] In agricultural irrigation spraying, agricultural nutrient solution spraying, or pesticide spraying, in order to achieve precise spraying of each plant or a row of plants with an appropriate dosage ratio, a control device adapted to such activities needs to be designed. Because its action unit is precise, it is the most advanced activity unit in smart agriculture. Combined with the spatial environment of the plants, its structure needs to be designed to meet the following characteristics: scientific structural design, spatial construction suitable for installation and integration with nozzles and pipes, and easy control.

[0003] These control devices are mostly implemented using electromagnetic control valves. However, ordinary electromagnetic valves are not suitable for sprinkler irrigation control in agricultural irrigation because: ordinary electromagnetic valves require structural fixation to coexist with the sprinkler head; they occupy a large longitudinal space and have significant structural protrusions; and their inlet and outlet designs do not meet the requirements of sprinkler irrigation, and the inlet and outlet diameters cannot meet the needs of miniaturization. Therefore, it is necessary to design a control electromagnetic valve with a miniaturized structure, no need for separate fixation, and a reasonable inlet and outlet diameter design. Utility Model Content

[0004] In view of the above-mentioned deficiencies of the prior art, the purpose of this utility model is to provide a fast-switching high-pressure solenoid valve.

[0005] The technical solution of this utility model is: a fast-switching high-pressure solenoid valve, including a horizontally arranged valve body, an iron core, a spring and a coil installed inside the valve body, a wiring port at the upper end of the valve body, a left-right extending sleeve fixed to the left end of the valve body, a flow guide sleeve fixed to the left end of the sleeve, an end cap fixed to the outside of the flow guide sleeve, a left-right extending guide tube at the center of the flow guide sleeve, an outlet inside the guide tube, an iron core extending left-right and housed inside the sleeve, a valve stem fixed to the left end of the sleeve, a plug fixed to the left end of the valve stem, a spring sleeved outside the plug, the plug located on the right side of the guide tube and used to block the outlet, an inlet located outside the guide tube on the flow guide sleeve, a flow channel inside the sleeve for connecting the inlet and outlet.

[0006] Furthermore, the spring extends to the left and right and is wedged between the outer wall of the left end of the valve stem and the inner wall of the left end of the sleeve.

[0007] Furthermore, the end cap is connected to a nozzle via a threaded connection.

[0008] Furthermore, the nozzle has an external thread in the middle, and the end cap has an internal thread, with the end cap screwed onto the external thread.

[0009] Furthermore, the nozzle has an outlet channel and an inlet channel located in the external threaded portion in the middle. The inlet channel is located outside the outlet channel. A guide tube is inserted into the outlet channel. The outlet is connected to the outlet channel, and the inlet channel is connected to the inlet.

[0010] Furthermore, an O-ring is fitted on the outer wall of the conduit, and the O-ring contacts the inner wall of the water outlet channel.

[0011] The advantages of using the fast-switching high-pressure solenoid valve provided by this utility model are: the valve body adopts a horizontal design, which will not occupy too much longitudinal space in actual use; the position where the end cap is connected to the nozzle is also the position where the water flow control valve is fixed, and due to its special inlet and outlet design, it can be directly attached to the nozzle connection position without the need for separate fixing; it has a separate power supply terminal, which is convenient for maintenance or disconnection.

Detailed Implementation

[0016] To provide a more intuitive and complete understanding of the technical solution of this utility model, the following non-limiting features are described in conjunction with the accompanying drawings:

[0017] like Figure 1 — Figure 3As shown, a fast-switching high-pressure solenoid valve includes a horizontally arranged valve body 1. An iron core 2, a spring 3, and a coil 4 are installed inside the valve body 1. A wiring port 5 is provided at the upper end of the valve body 1. A sleeve 6 extending laterally is fixed to the left end of the valve body 1. A guide sleeve 7 is fixed to the left end of the sleeve 6. An end cap 8 is fixed to the outside of the guide sleeve 7. A guide tube 71 extending laterally is located at the center of the guide sleeve 7. An outlet 711 is located inside the guide tube 71. The iron core 2 is housed within the sleeve 6. A valve stem 9 is fixed to the left end of the sleeve 6. A plug 10 is fixed to the left end of the valve stem 9. The spring 3 is sleeved outside the valve stem 9. The plug 10 is located on the right side of the guide tube 71 and is used to block the outlet 711. An inlet 72 is also provided on the guide sleeve 7, located outside the guide tube 71. A flow channel 61 is located inside the sleeve 6, which connects the inlet 72 and the outlet 711.

[0018] like Figure 2 As shown, spring 3 extends to the left and right, wedged between the outer wall of the left end of valve stem 9 and the inner wall of the left end of sleeve 6. When energized, iron core 2 moves to the right under the action of coil 4, plug 10 moves away from outlet 711, outlet 711 is opened, and spring 3 is compressed. After de-energization, under the elastic force of spring 3, iron core 2 will drive valve stem 9 and plug 10 to reset, closing outlet 711, thus achieving the function of locking water.

[0019] The end cap 8 is connected to a nozzle 11 via a threaded connection. A sealing ring can be installed between the end cap 8 and the nozzle 11 to prevent water leakage. Figure 1 , Figure 3 As shown, the nozzle 11 has an external threaded portion 111 in the middle, and the end cap 8 has an internal thread. The end cap 8 is screwed onto the external threaded portion 111. The nozzle 11 has an outlet channel 112 and an inlet channel 113 located within the external threaded portion 111. The inlet channel 113 is located outside the outlet channel 112. The conduit 71 is inserted into the outlet channel 112, with the outlet 711 communicating with the outlet channel 112, and the inlet channel 113 communicating with the inlet 72. To prevent water from the inlet channel 113 from directly entering the outlet channel 112, an O-ring 12 is fitted on the outer wall of the conduit 71, and the O-ring 12 contacts the inner wall of the outlet channel 112.

[0020] The high-pressure solenoid valve with quick switching provided by this utility model has a valve body 1 with a horizontal design, which will not occupy too much vertical space in actual use; the end cap 8 is connected to the nozzle 11 at the same position as the fixed water flow control valve. Due to its special inlet and outlet design, it can be directly attached to the nozzle 11 without additional fixing; it has a separate power supply terminal 5, which is convenient for maintenance or disconnection.

[0021] Of course, the above are only preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any simple modifications and equivalent structural changes made based on the contents of the present utility model specification and drawings should also be included within the patent protection scope of the present utility model.
