Abstract

The invention relates to an electromagnetic valve. The electromagnetic valve comprises a lower valve seat, an upper valve seat, a stainless steel pipe, a lower valve seat sealing ring, an upper valve seat sealing ring, a movable valve core, a plug, a spring, a fixed valve core, a sealing plate, a coil, a sleeve and an upper cover shell, wherein the upper valve seat is arranged on an electromagnetic valve base of the lower valve seat through an installation groove; the sealing plate is arranged on the upper valve seat; the lower valve seat, the upper valve seat and the sealing plate are fixed together by four screws; one end of the movable valve core is connected with the plug, and the other end of the movable valve core is connected with the spring; the fixed valve core is arranged in thesleeve and is contacted with one end of the spring; one end of the sleeve is fixed in a hole in the middle of the sealing plate in an interference fit mode, and the other end of the sleeve is fixed in a hole in the middle of the upper cover shell in the interference fit mode; the coil is wound in the middle of the sleeve; and the upper cover shell is connected with the sealing plate through a bolt. The on-off of three water outlets on the electromagnetic valve can be controlled independently, and a one-inlet three-outlet function is realized.

Description

technical field [0001] The invention relates to an electromagnetic valve, in particular to an electromagnetic valve capable of independently controlling the on-off of three water outlets. Background technique [0002] At present, solenoid valves on the market are generally connected to pipes through threaded structures. If they want to be connected to plastic hoses, they need to use auxiliary parts with threads. At the same time, it is not easy to install. The cost performance is not high, and it is not suitable for application in compact electrical equipment. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art and provide a solenoid valve capable of independently controlling the on-off of three water outlets. [0004] The structure of the present invention includes: a lower valve seat containing three electromagnetic valve bases, an upper valve seat, a stainless steel pipe, a lower valve seat sealing ri...
