Description

Solenoid valve

Technical field

The present invention relates to a kind of solenoid valve, be specifically related to a kind of solenoid valve with three water outlet break-makes of independent control.

Background technique

At present, solenoid valve on the market generally is to link to each other with pipe by worm structure, if link to each other with plastic flexible pipe, then need be by screwed auxiliary member, be not easy to simultaneously install, have simultaneously that overall volume is big, price is expensive, the not high shortcoming of cost performance, also be unsuitable for being applied in the electrical equipment of compact structure simultaneously.

Summary of the invention

The objective of the invention is in order to overcome the prior art deficiency, a kind of solenoid valve with three water outlet break-makes of independent control is provided.

Structure of the present invention comprises: contain the base of three solenoid valves lower valve base, upper valve base, stainless steel pipe, lower valve base seal ring, upper valve base seal ring, movable spool, plug, spring, fixed spool, sealing plate, coil, sleeve, upper encloser; Three upper valve bases are placed in respectively on three solenoid valve base of lower valve base, and by the location of the mounting groove on three solenoid valve base of lower valve base, and the water inlet and outlet aperture of upper valve base and lower valve base pipe is parallel; Sealing plate is placed on the upper valve base, sealing plate four mounting holes alignment of four mounting holes and upper valve base, the lower valve base seal ring is placed between the solenoid valve base and upper valve base of lower valve base, the upper valve base seal ring is placed between upper valve base and the sealing plate, with four screws lower valve base, lower valve base seal ring, upper valve base, upper valve base seal ring and sealing plate is fixed together; Plug is installed in the end that movable spool has cap, and an end that will have a plug places in the lower valve chamber that solenoid valve base and corresponding upper valve base by lower valve base constitute; The other end cover upper spring of movable spool, and an end that will have a spring places in the fixed spool; Fixed spool places in the sleeve, and contacts with spring one end; Hole in the middle of one end of sleeve and the sealing plate links together sleeve and sealing plate with the form of interference fit, and the hole in the middle of the other end of sleeve and the upper encloser links together sleeve and upper encloser with the form of interference fit, and the centre of sleeve is wound with coil; Be connected by bolt between upper encloser and the sealing plate.

The invention has the beneficial effects as follows: the break-make of three water outlets on can independent control electromagnetic valve, can realize that one advances three functions that go out, to be convenient to install, water inlet and outlet aperture pipe is convenient to connect plastic flexible pipe, has that volume is little, simple in structure, the cost performance advantages of higher.
