[0002] At present, in the existing technology, there are generally two types of exhaust brake valves for garden and urban greening: an electric type using a solenoid valve and a vacuum type using a vacuum cylinder, which are used for watering and irrigation of garden and urban greening. When the water supply pressure is unstable and there is no power supply, a self-holding intelligent pressure regulating solenoid valve integrating manual and automatic functions is required to regulate the water supply pressure.

Detailed implementation manner

[0024] Refer to Figures 1-7 , an electromagnetic pressure regulating valve, including an electromagnetic pressure regulating valve body, on which there are a water inlet 1, a first water outlet 2 and a second water outlet 3. The water body enters from the water inlet 1, and then by rotating the manual valve 4, it is selected that the water body flows out from one or both of the first water outlet 2 and the second water outlet 3, so as to achieve the effect of selecting the outflow. A manual valve 4 for stopping the flow is also installed on the electromagnetic pressure regulating valve body, or the direct blocking of the water body is completed through the manual valve 4.

[0025] Refer to Figure 7 As shown, the electromagnetic pressure regulating valve body has a first cavity 11, a second cavity 13 and a third cavity 14. The first cavity 11 is communicated with the second cavity 13 through a communication hole 12, and the second cavity 13 is communicated with the third cavity 14 through a drain hole 16. Therefore, the water body flows in from the water inlet 1. In the open state of the manual valve 4, the water body will enter the first cavity 11. Since there is also an electromagnetic head 17 for driving the water flow in the electromagnetic pressure regulating valve body, and the electromagnetic head 17 is used to drive the flow of the water fluid, the water body originally existing in the first cavity 11 will be pumped out through the communication hole 12 and transported to the second cavity 13;

[0026] Then, this part of the water body will enter the third cavity 14 through the drain hole 16 again. Since there is also a fourth cavity 15 communicated with the first water outlet 2 and the second water outlet 3 in the electromagnetic pressure regulating valve body at this time, and the fourth cavity 15 is blocked by the manual valve 4 from the third cavity 14, the water body will not flow out at this time.

[0027] It should be noted that, refer to Figures 4-6 As shown, a filter screen 18 for filtering the water body is also provided in the electromagnetic pressure regulating valve body. This part of the filter screen 18 is used to effectively filter and remove impurities from the water body. At the same time, the filter screen 18 is a detachable structure, which is convenient for subsequent replacement, cleaning and maintenance.

[0028] A flow pipe 19 for diverting water is also provided in the body of the electromagnetic pressure regulating valve, and a flow channel 20 for facilitating the flow of water is opened on the flow pipe 19. It should be noted that the water will flow through the flow channel 20 in the flow pipe 19, wherein the flow channel 20 is curved, and is used to block and buffer the water flow, thereby achieving a decompression effect on the water body. Furthermore, the caliber of the flow channel 20 is adjustable, and the pressure state can be better adjusted. The caliber of the flow channel 20 is adjusted according to the prior art and will not be elaborated on here.

[0029] A diaphragm 10 is provided in the first cavity 11, and a pre-tightening portion for pre-tightening the diaphragm 10 is provided on the electromagnetic pressure regulating valve body, which is used to pre-tighten the diaphragm 10 and adjust the closure of the water flow and the pressure of the water flow. When the first cavity 11 is filled with water, the diaphragm 10 will be pressed down and against the closed fourth cavity 15, and the adjustment of the diaphragm 10 is achieved by rotating the pre-tightening portion.

[0030] Reference Figures 1-3 As shown, the pre-tightening part includes a threaded tooth 7, a knob 6 and a push head 8 are provided on the threaded tooth 7, and an adjusting rod 9 is provided at the end of the threaded tooth 7, the adjusting rod 9 is against the diaphragm 10, the knob 6 drives the threaded tooth 7 to rotate, and the push head 8 moves along the axis through the rotating threaded tooth 7, and the outer cover of the pre-tightening part is provided with a protective shell 5, wherein the threaded tooth 7 is driven to rotate by rotating the knob 6, and then the push head 8 is pushed forward and against the adjusting rod 9, and then the adjusting rod 9 is made to press against the diaphragm 10 located in the electromagnetic pressure regulating valve body, thereby realizing the adjustment of the diaphragm 10, thereby solving the problem that the diaphragm 10 is not tightly fastened during the closing process of the manual valve 4, and the problem of leakage is very likely to occur.

[0031] The working principle of the utility model is as follows:

[0032] Since the electromagnetic pressure regulating valve body has a water inlet 1, a first water outlet 2 and a second water outlet 3, water enters from the water inlet 1, and the water flows in from the water inlet 1. When the manual valve 4 is opened, the water enters the first cavity 11. Since the electromagnetic pressure regulating valve body is also provided with an electromagnetic head 17 for driving the flow of water, wherein the electromagnetic head 17 is used to drive the flow of the water fluid, the water originally in the first cavity 11 is extracted through the connecting hole 12 and transported to the second cavity 13;

[0033] The filter screen 18 is used to effectively filter and remove impurities from the water body. At the same time, the filter screen 18 is a detachable structure, which is convenient for subsequent replacement, cleaning and maintenance. The flow channel 20 is curved and is used to block and buffer the water flow, thereby achieving a decompression effect on the water body.

[0034] Then, by rotating the manual valve 4, select whether the water body flows out from one or both of the first water outlet 2 and the second water outlet 3, so as to achieve the effect of selecting the outflow. A manual valve 4 for stopping the flow is also installed on the electromagnetic pressure regulating valve body, or the direct blocking of the water body is completed through the manual valve 4.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
