Detailed Description

As shown in the figure, the filtering type electromagnetic valve comprises an electric wire 101, a junction box 103, a timer 104, a control assembly and a Y-shaped filtering valve 300 which are connected in sequence. The telecom 101 is connected with a junction box 103, a timer 104 is inserted into the junction box 103, and the junction box 103 is fixedly connected with the timer 104 by using a screw 102. The power supply 101 is turned on, the on and off times are set by the timer 104, and the timer 104 is turned on when the preset start time is reached.

The Y-shaped filter valve 300 comprises a valve body 301, wherein an inlet cavity 304, a blowdown cavity 305, at least one diversion cavity 306, a seat hole 307, a communication cavity 303 and an outlet cavity 302 which are sequentially communicated are arranged in the valve body 301, preferably, the number of the diversion cavities 306 is three, the three diversion cavities 306 are distributed around the communication cavity 303 in a semi-annular shape, and the communication position of the diversion cavities 306 and the seat hole 307 and the communication position of the seat hole 307 and the communication cavity 303 are at the same horizontal height. The multiple groups of guide cavities 306 can improve the stability of water flow circulation in the valve body 301. One ends of the inlet cavity 304, the sewage cavity 305, the seat hole 307 and the outlet cavity 302 are respectively communicated with the outside of the valve body 301. A screen cylinder 105 is disposed within the waste chamber 305, preferably, the screen cylinder 105 is a stainless steel screen cylinder. So that water entering the drainage chamber 305 can enter the diversion chamber 306 after passing through the filter screen cylinder 105. The end of the sewage draining cavity 305 communicated with the outer end of the valve body 301 is connected with a screw cap 107 through threads, and the screw cap 107 is made of brass. The nut 107 seals the outlet of the dirt discharge chamber 305 communicating with the outer end of the valve body 301. In order to improve the sealing effect, an O-ring 106 is arranged between the screw cap 107 and the valve body 301.

The control assembly comprises a shell 201, a coil 206, a magnetism isolating pipe 207 and a movable iron core 203 are installed in the shell 201 in a matched mode, the movable iron core 203 is arranged in the magnetism isolating pipe 207, one end of the movable iron core 203 is connected with a spring 202, and the other end of the movable iron core 203 is fixedly connected with a sealing gasket 204. One end of the magnetism isolating pipe 207 is inserted into the seat hole 307 and connected with the valve body 301. Specifically, an external thread is arranged on the outer circumferential surface of one end of the magnetism isolating pipe 207 inserted into the seat hole 307, an internal thread is arranged on the hole wall of the seat hole 307, and the magnetism isolating pipe 207 is in threaded connection with the valve body 301. In order to improve the sealing effect, an O-ring 205 is arranged between one end of the magnetism isolating pipe 207 inserted into the seat hole 307 and the seat hole 307.

When the coil 206 is in an energized state, the sealing gasket 204 covers the communication between the flow guide cavity 306 and the seat hole 307, and covers the communication between the seat hole 307 and the communication cavity 303, so that the flow guide cavity 306 is not communicated with the seat hole 307, and the seat hole 307 is not communicated with the communication cavity 303. In the de-energized state of the coil 206, the sealing gasket 204 is away from the place where the diversion cavity 306 is communicated with the seat hole 307, and is away from the place where the seat hole 307 is communicated with the communication cavity 303, so that the diversion cavity 306 is communicated with the seat hole 307, and the seat hole 307 is communicated with the communication cavity 303.

The working principle is as follows:

when the electromagnetic valve works, a medium enters through the inlet cavity 304 and flows to the sewage discharge cavity 305, the outlet of the sewage discharge cavity 305 is closed, the medium flows to the three diversion cavities 306 through the filter screen cylinder 105 respectively, and impurities are left in the filter screen cylinder 105. By adjusting the timer 104 to set the opening and closing time, when the timer 104 is powered on, the coil 206 generates electromagnetic force, which in turn drives the plunger 203 to move upward, the spring 202 is compressed, the sealing pad 204 is lifted, and the valve is opened. The liquid in the diversion chamber 306 flows into the communication chamber 303 through the seating hole 307, flows to the outlet chamber 302, and finally flows out of the outlet chamber 302. When the power is off, the electromagnetic force disappears, the movable iron core 203 descends under the action of the elastic force of the spring 202 and presses the sealing gasket 204 at the position where the diversion cavity 306 is communicated with the seat hole 307 and the position where the seat hole 307 is communicated with the communication cavity 303, and the valve is closed. Removal of the screw cap 107 allows impurities in the filter cartridge 105 to drain through the waste chamber 305.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
