Detailed Description

The present application is described in further detail below in conjunction with figures 1-2.

The embodiment of the application discloses a two-way electromagnetic valve. Referring to fig. 1, the two-way solenoid valve includes a valve body 1, a valve cover 2, a solenoid assembly 3, and a rubber piston 4 engaged with the solenoid assembly 3. The electromagnetic assembly 3 is mounted on the valve cover 2, wherein the rubber piston 4 is in a normally open state.

Referring to fig. 1 and 2, a conversion chamber 11 is formed on one side of the valve body 1, which is close to the valve cover 2, and a rubber piston 4 is partially positioned in the conversion chamber 11. The two sides of the valve body 1 perpendicular to the cavity opening of the conversion cavity 11 are respectively provided with a water inlet 12 and a water outlet 13. A partition sleeve 14 is arranged on one side of the water inlet 12, which is close to the water outlet 13, and the partition sleeve 14 is positioned inside the valve body 1. The axial direction of the partition sleeve 14 is perpendicular to the direction of the water flow, and the top of the partition sleeve 14 is communicated with the conversion cavity 11, that is, the axial direction of the partition sleeve 14 is the opening direction of the conversion cavity 11. When the rubber piston 4 is abutted against the top of the partition sleeve 14, the water inlet 12 is not communicated with the conversion cavity 11; in contrast, when the rubber piston 4 is not abutted against the top of the partition sleeve 14, the water inlet 12 is communicated with the conversion cavity 11.

Referring to fig. 1 and 2, a valve cover 2 is disposed on one side of a valve body 1 where a conversion cavity 11 is formed, the valve cover 2 shields an opening of the conversion cavity 11, and the valve cover 2 is mounted on the valve body 1 by bolts. The solenoid assembly 3 is mounted to the side of the valve cover 2 facing away from the valve body 1. The electromagnetic assembly 3 comprises an iron core tube 31 arranged on the valve cover 2, a coil 32 sleeved on the iron core tube 31, a movable iron core 33 slidably arranged in the iron core tube 31 and a driving spring 34 arranged in the iron core tube 31 and used for driving the movable iron core 33 to abut against the valve cover 2.

The pore wall of the water inlet 12 is provided with a water outlet channel, the inside of the valve cover 2 is provided with a water inlet channel communicated with the water outlet channel, and the water inlet channel is communicated with the inside of the iron core tube 31. The valve cover 2 is also provided with a drainage channel communicated with the conversion cavity 11, and the drainage channel is communicated with the interior of the iron core tube 31.

Referring to fig. 1 and 2, when the water inlet 12 and the water outlet 13 are communicated, the movable iron core 33 blocks the water inlet passage under the action of the driving spring 34, so that the water inlet passage is not communicated with the inside of the iron core tube 31, and the rubber piston 4 is not abutted with the top of the partition sleeve 14.

When the water inlet 12 and the water outlet 13 are not communicated, the coil 32 drives the movable iron core 33 to move, so that the movable iron core 33 does not block the water inlet channel, and water flows sequentially through the water outlet channel, the water inlet channel, the iron core tube 31 and the water outlet channel to form higher water pressure so as to drive the rubber piston 4 to abut against the top of the partition sleeve 14. An assisting spring 46 assisting the deformation movement of the rubber piston 4 and abutting against the partition sleeve 14 is arranged between the rubber piston 4 and the valve cover 2. The elastic force of the auxiliary spring 46 is smaller than the deformability of the rubber piston 4, so that the auxiliary spring 46 is pressed after the rubber piston 4 is automatically reset, and the valve body 1 is in a normally open state.

Referring to fig. 1 and 2, the rubber piston 4 includes a blocking post 41, a sealing bead 42, and an arcuate bending ring 43. The blocking post 41, the sealing flange 42 and the arc-shaped bending ring 43 are integrally formed. The arc bending ring 43 is sleeved on the blocking column 41, the inner peripheral wall of the arc bending ring 43 is connected with the outer peripheral wall of the blocking column 41, and the outer side of the arc bending ring 43 is connected with the sealing convex edge 42. The outer diameter of the sealing flange 42 is larger than the caliber of the cavity mouth of the conversion cavity 11, and the sealing flange 42 is clamped by the valve body 1 and the valve cover 2. The blocking column 41 is abutted against the top of the partition sleeve 14 to block the communication part between the water inlet 12 and the conversion cavity 11.

The sealing convex edge 42 is abutted against the valve body 1 at one side close to the valve body 1, the valve cover 2 is provided with a groove 21 for installing the sealing convex edge 42, and then the valve body 1 and the valve cover 2 are matched to clamp and limit the sealing convex edge 42. A plugging bottom ring 44 is arranged on one side of the sealing convex edge 42, which is close to the valve body 1, and a ring groove 15 for inserting the plugging bottom ring 44 is arranged on the valve body 1; a plug-in top ring 45 is arranged on one side of the sealing convex edge 42, which is close to the valve cover 2, and a slot 22 for inserting the plug-in top ring 45 is arranged at the bottom of the groove 21.

Referring to fig. 1 and 2, the arc bending ring 43 is located inside the conversion cavity 11, the arc top of the arc bending ring 43 faces the valve cover 2, and a deformation cavity 23 into which the arc bending ring 43 is inserted is formed on one side of the valve cover 2 close to the arc bending ring 43. When the water pressure of the blocking column 41 near the valve cover 2 is higher than the water pressure of the blocking column 41 near the partition sleeve 14, the arc-shaped bending ring 43 deforms to enable the blocking column 41 to move towards the partition sleeve 14 and abut against the partition sleeve 14.

The blocking sleeve 14 is provided with a blocking ring 16 on a side close to the blocking post 41, and the blocking post 41 is provided with a blocking slot 411 into which the blocking ring 16 is inserted. The inner and outer edges of the partition ring 16 adjacent to the blocking column 41 are provided with arc surfaces for facilitating insertion of the partition ring 16 into the partition slot 411.

The implementation principle of the two-way electromagnetic valve in the embodiment of the application is as follows: the sealing flange 42 is limited by the clamping of the valve body 1 and the valve cover 2. When the water inlet 12 and the water outlet 13 are communicated, the movable iron core 33 shields and blocks the water inlet channel under the action of the driving spring 34, so that the water inlet channel is not communicated with the interior of the iron core tube 31, at the moment, the blocking column 41 is not abutted against the top of the partition sleeve 14 under the elastic capability of the arc bending ring 43, and water flow enters the conversion cavity 11 through the water inlet 12 and is finally discharged from the water outlet 13.

When the water inlet 12 and the water outlet 13 are not communicated, the coil 32 drives the movable iron core 33 to move, so that the movable iron core 33 does not block the water inlet channel, and water flows sequentially through the water outlet channel, the water inlet channel, the iron core tube 31 and the water outlet channel to form higher water pressure so as to drive the blocking column 41 to move to the side close to the partition sleeve 14 and abut against the partition sleeve 14. During the movement of the occlusion post 41, the arcuate bending ring 43 will deform. The whole motion process of the rubber piston 4 mainly generates bending deformation, and the rubber piston 4 is not easy to rub with the valve body 1 or the valve cover 2 to generate loss in the moving process, so that the service life is longer.

The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
