DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.

[0031] The embodiment of the utility model relates to a corrosion-resistant radar cleaning solenoid valve, such as Figure 1-14 As shown, it includes a coil group 100, a fixed group 200, a movable diaphragm group 300 and an electromagnetic valve seat 601, wherein the electromagnetic valve seat 601 is provided with an inlet channel 603, a plurality of valve chambers 604 communicating with the inlet channel 603, and a plurality of outlet channels 605 respectively communicating with the plurality of valve chambers 604, the fixed group 200 includes an iron frame 201 and a plurality of fixed iron cores 202, the upper end of the electromagnetic valve seat 601 is installed with an iron frame 201, the upper end of the electromagnetic valve seat 601 is located in the iron frame 201 and a plurality of coil groups 100 are arranged side by side, the plurality of coils The coil groups 100 correspond to the multiple valve chambers 604 respectively, and a movable diaphragm group 300 is installed in each coil group 100. The movable diaphragm group 300 includes a movable iron core 301 and a sealing diaphragm 302. The sealing diaphragm 302 is installed at the lower end of the movable iron core 301. The sealing diaphragm 302 is used to block the connection between the corresponding inlet channel 603 and the outlet channel 605. The top of the iron frame 201 is located above each movable iron core 301, and a fixed iron core 202 is installed, and a spring 303 is installed between the fixed iron core 202 and the corresponding movable iron core 301.

[0032] The coil assembly 100 provides the excitation condition to control the movement of the movable diaphragm assembly 300 to switch the valve. The movable diaphragm assembly 300 is an isolated core component that isolates the medium from the iron core so that it cannot produce a chemical reaction to generate a potential difference. When the movable diaphragm assembly 300 is in the demagnetized state, the tensile force of the sealing diaphragm 302 plus the restoring force of the spring 30 can accelerate the reset of the movable diaphragm assembly 300. During the accelerated reset process of the sealing diaphragm 302, the medium flow is accelerated to clear the residual cleaning medium in the chamber, reduce the chemical reaction of the active additives of the medium to rubber and plastic, and effectively reduce the variation of the internal material of the solenoid valve.

[0033] A row of clamping jaws 203 are arranged on both sides of the lower end of the iron frame 201, each of which includes two symmetrically arranged clamping jaws. A clamping portion 602 cooperating with the clamping jaws 203 is arranged on the solenoid valve seat 601; Figure 7As shown in the diagram at A, the electromagnetic valve seat 601 is quickly connected to the iron frame 201 by the cooperation of the clamping part 602 and the clamping jaw group 203.

[0034] The plane of the clamping portion 602 is lower than the plane of the electromagnetic valve seat 601. When resisting the blasting water pressure, the iron frame 201 contracts inwards due to deformation stress and squeezes the valve seat to increase the anti-blasting capability.

[0035] The sealing diaphragm 302 is a disc-shaped structure made of elastic material. The middle part of the sealing diaphragm 302 is arched to form a middle area 306 that can reciprocate. The middle area 306 reciprocates to open or close the connection between the inlet channel 603 and the outlet channel 605. A circle of arc-shaped disturbance part 307 is arranged between the middle area 306 and the edge part of the sealing diaphragm 302. The lower end surface of the middle area 306 is a horizontal plane. The valve cavity 604 adopts a centralized drainage design. The design of the horizontal plane and the valve cavity 604 can increase the drainage flow rate and the emptying of the chamber medium. The arc design of the disturbance part 307 can effectively reduce the vortex to guide the medium to the outlet and reduce the contact time of the medium.

The fixed group 200, the movable diaphragm group 300 and the conductive magnetic disk 400 provide an excitation circuit.
