Abstract

The utility model provides a direct drive type two-position four-way electromagnetic valve which adopts a balancing type sealing structure and comprises a valve body, valve seats and a valve rod component. The valve body is provided with four medium inlet and outlet end openings, and a connecting channel is arranged between the top end opening and the bottom end opening to connect the top end opening with the bottom end opening; four valve seats corresponding to the four end openings are arranged in the valve body, a valve plug group forming a valve plug component forms a sealing plane with four valve seats, thus a valve body communicating type sealing structure is formed. After the medium enters the valve body, the valve rod component can be balanced by an upward thrust and downward pressing medium force, thus the direct drive type two-position four-way electromagnetic valve of the valve body communicating and pressure balancing type sealing structure is formed. The direct drive type two-position four-way electromagnetic valve has the advantages that the electromagnetic valve can work in a vacuum condition and can realize non pressure difference working, one end opening is pressurized, or a plurality of end openings are pressurized alternately, and the reversing function can be flexibly exerted, and the direct drive type control of the large caliber electromagnetic valve can be achieved in a more economical electromagnet range.

Description

Direct-acting type two-position four-way solenoid valve

Technical field

The utility model relates to the solenoid valve of using in the automation control, particularly relates to a kind of direct-acting type two-position four-way solenoid valve.

Background technique

Solenoid valve is the pipe-line system executive component of control automatically, has two formula actions of open and close, and general solenoid valve is to promote the valve plug to-and-fro motion by transmitting pressure, realizes closing valve or driving valve.Since solenoid valve at work in the valve seat variation in pressure of medium very big, influence to electromagnet suction is very big, therefore common solenoid valve can only one-way only operation, promptly MEDIA FLOW according to the rules could realize the function of solenoid valve when using, usually be applied in the pneumatic control, can not realize water, gas, oily media general.

Summary of the invention

The technical problems to be solved in the utility model, provide a kind of MEDIA FLOW pressure and flow direction of not being subjected to and influence the effect that only is subjected to spring force, gravity and electromagnetic force, thereby reach solenoid valve not by medium differential pressure work, realize that MEDIA FLOW two-wayly all can work to positive and negative, and at the direct-acting type two-position four-way solenoid valve that the valve pocket connection pressure balance seal structure that all can work under pressure reduction and the no pressure reduction state is being arranged.

The technological scheme that adopts is:

Direct-acting type two-position four-way solenoid valve adopts the pressure balance type sealing configuration, comprises valve body, valve seat, valve rod assembly.Described valve body is provided with the port that four media advance or go out, be provided with the MEDIA FLOW circulation passage between wherein uppermost port and the nethermost port, uppermost port and nethermost port are communicated with, in valve body, be provided with and four corresponding four valve seats of port, the cypriot valve components that is contained on the valve rod by four valve plugs can constitute sealing surface with four valve seats, form valve body communication type sealing configuration, after medium enters valve body, can make valve rod assembly be subjected to upwards pushing away and reaching balance, constitute the direct-acting type two-position four-way solenoid valve of pressure balance type sealing configuration to the medium power that presses down.

The utility model has the advantages that:

1, adopts the solenoid valve of this kind seal form because when negative pressure, can guarantee normal solenoid valve function, therefore can under the condition of vacuum, work.

2, adopt the solenoid valve of this kind seal form to overthrow the rule that medium needs orientation to circulate, can realize that in two-position four-way solenoid valve two ports replace supercharging, its commutation function is brought into play in a port emptying flexibly.

3, can realize not having pressure reduction work.

4, can in the electromagnet scope of less expensive, realize the direct-acting type control of larger caliber solenoid valve.

5, be applicable to the control of water, gas, oily medium.
