Description

Technical Field

[0001] The utility model relates to the technical field of valve bodies, and particularly relates to a water passing valve. Background Art

[0002] Household appliances are common furniture items. Washing machines, refrigerators, and air conditioners all need to drain and supply water. Therefore, during use, a valve body needs to be installed on the pipeline to control the drainage and water supply functions of the pipeline. For example, Figure 8 is an existing valve body for washing machines, refrigerators, and air conditioners. This valve body mainly uses an electromagnetic coil body to drive the iron core to move, so that the iron core can block or dredge the water outlet hole. In the existing valve body, the guide rod is used for the movement of the iron core and is also relatively fixed to the electromagnetic coil. The existing guide rods are all provided with four elastic claw feet at the top, and then the guide rod is passed through the positioning holes of the electromagnetic coil body and the cross beam plate, and then the plug column is pressed into the four elastic claw feet by equipment, so that the four claw hands can be outwardly extended, prompting the four claw hands not to pass through the positioning holes, thereby fixing the position of the guide rod;

[0003] However, this fixing method is not only cumbersome in steps, but also uses a lot of materials and is costly; at the same time, the existing diaphragm has 6 water inlet holes and 1 water passing hole. This diaphragm is not universal with the classic large screw valve during actual use, and the material management cost is high. Therefore, this application provides a water passing valve that is more material - cost - saving. Summary of the Utility Model

[0008] a guide rod, which is integrally formed with the sealing cover. The outer circumferential wall of the guide rod is provided with a plurality of uniformly arranged first ribs, and the first ribs are distributed along the extending direction of the guide rod;

[0009] Among them, the guide rod is press - fitted on the inner wall of the electromagnetic coil group. The first ribs are in interference fit with the inner wall of the electromagnetic coil group, and the guide rod slidably penetrates through the through - holes of the flat plate and the clamping plate.

[0030] a guide rod 31, integrated with the sealing cover 30, a number of uniformly arranged first ribs 32 are provided on the outer circumferential wall of the guide rod 31, and the first ribs 32 are distributed along the extending direction of the guide rod 31;

[0031] a flat plate 92, fixedly connected to the valve body 10 by bolts;

[0032] a clamping plate 91, in a U shape, two opposite side walls are respectively fixedly connected to the flat plate 92, and the opposite surfaces of the clamping plate 91 and the flat plate 92 are used to clamp the electromagnetic coil group 90;

[0033] Among them, the guide rod 31 is press-fitted on the inner wall of the electromagnetic coil group 90, the first ribs 32 are in interference fit with the inner wall of the electromagnetic coil group 90, and the guide rod 31 slidably penetrates through the through holes of the flat plate 92 and the through holes of the positioning 91 plate;

[0034] an iron core 60, slidably extending into the guide rod 31, one end of the iron core 60 extending into the guide rod 31 has a limiting body 62, the diameter of the limiting body 62 is smaller than the diameter of the iron core 60, and one end of the iron core 60 extending out of the guide rod 31 has a positioning body 61;

[0035] a spring 80, extending into the guide rod 31, one end of the spring 80 is fixedly connected to one end of the iron core 60 extending into the guide rod 31;

[0036] a sleeve 70, fixedly sleeved on the positioning body 61 and fixedly connected to the diaphragm 40, and the sleeve 70 is opposite to the water outlet hole 41 on the diaphragm 40.

[0037] This embodiment is implemented as follows:

[0038] During the assembly of this application, by providing the first rib 32 on the outer circumferential wall of the guide rod 31, during the assembly process, through a press-fitting device, the guide rod 31 is pressed into the electromagnetic coil group 90. At this time, the first rib 32 on the guide rod 31 is in interference fit with the inner wall of the electromagnetic coil group 90, so that the electromagnetic coil group 90 can clamp the first rib 32 of the guide rod 31. At this time, the guide rod 31 penetrates through the through holes of the clamping plate 91 and the flat plate 92, which makes this application save the material cost of the plug post and the claw feet compared with the prior art and can effectively reduce the production cost of the enterprise.

[0039] At the same time, in this application, by providing the second rib 34 on the outer wall of the sealing cover 30, the second rib 34 can be in interference fit with the control cavity 20, so that the sealing cover 30 can be held in the control cavity 20, which is more stable than directly placing the sealing cover 30 in the control cavity 20 in the prior art;

[0040] In this application, the flat plate 92 is fixedly connected to the valve body 10 by bolts, and the clamping plate 91 is fixed on the flat plate 92, so that the flat plate 92 and the clamping plate 91 can clamp the electromagnetic coil group 90.

[0043] When the electromagnetic coil group 90 is energized, the iron core 60 is sucked upwards, so that the iron core 60 can slide in the chute of the guide rod 31 and compress the spring 80. At this time, the iron core 60 will drive the sleeve 70 to move, so that the sleeve 70 is separated from the diaphragm 40. At this time, the diaphragm 40 will be pushed open by the water pressure of the water inlet pipe 13, so that the water in the water inlet pipe 13 can enter the water outlet pipe 12.

[0044] In this application, the existing diaphragm with six water inlet holes and one water outlet hole is abandoned, and the classic diaphragm 40 with one water inlet hole and one water outlet hole is adopted, which can reduce the material management cost of the diaphragm 40 and improve the versatility.

[0045] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
