Rubber sealing structure is generally used with spool, rubber sealing structure needs to consider under different media using different materials, rubber
Glue is easy aging in use, reduces the service life, and rubber sealing structure also needs handware to be fixed, and uses
It is at high cost.
Summary of the invention
In view of the deficiencies of the prior art, the utility model provides a kind of diverter flow proportional solenoid valve mechanical seal knot
Structure.
The technical solution of the utility model are as follows: diverter flow proportional solenoid valve mechanical seal structure, it includes: valve nozzle part
And the top of valve body is arranged in core member, the valve nozzle part, the bottom of the valve nozzle part connects core member, the bottom of the core member
Portion is connect with copper core, and the bottom of the copper core is arranged with elastic slice, is provided with annular groove A at the top of the valve nozzle part, is convenient for and valve
Close connection, the bottom of the valve nozzle part are provided with through-hole at the top of body, and for liquid out, funnel-form chamber is formed inside the valve nozzle part
Body, the funneling cavities are connected with communicating pipe, and the bottom of the communicating pipe is provided with chamfering A, and the top of the core member is
Boss structure is provided with chamfering B at the top of the boss, and for the chamfering A cooperation with valve nozzle bottom, it is close to form mechanical chamfering
Envelope, the side of the boss are provided with cavity, and the cavity is located at the top of through-hole, and the bottom of the core member is provided with annular groove
B, convenient for closely being connect with copper core.
Further, the chamfering A and axle center are at 15 ° of angles.
Further, the chamfering B and axle center are at 35 ° of angles.
Working principle of the utility model is: valve body is normally open valve, after valve body power-off, core member is downward by the elastic force of elastic slice
It draws, valve is opened, and when valve body is powered, core member is pushed up upwards by electromagnetic force, passes through the chamfering of valve nozzle part and core member
Setting forms sealing, and valve is closed, since the chamfering of valve nozzle part and core member is arranged, when core member pulls down, and valve nozzle part and valve
Chipware can be separated easily, when core member is pushed up upwards, by the cooperation of chamfering A and chamfering B, form mechanical chamfering sealing.
The utility model has the following beneficial effects: (1) the utility model structure is simple, production cost is reduced；(2) this structure
