Abstract
The invention relates to a direct-acting type two-position four-way solenoid valve, which adopts a pressure balancing type sealing structure and comprises a valve body, valve seats and a valve rod assembly. The valve body is provided with four ports for in and out of media; wherein a connecting channel is arranged between the top port and the bottom port and connects the top port and the bottom port; the valve body is internally provided with four valve seats corresponding to four ports; a valve plug group forming the valve rod assembly and the four valve seats form seal surfaces so as to form a communicated sealing structure of the valve body; when the media enter the valve body, the medium force of pushing upward and pressing downward can be applied to the valve rod assembly to achieve balance so as to form the direct-acting type two-position four-way solenoid valve which adopts the pressure balancing type sealing structure with the communicated valve body. The solenoid valve can work under the condition of vacuum and can realize work without pressure difference in such a way that one port is pressurized or a plurality of ports are pressurized alternatively, thus playing the reversing function flexibly. The solenoid valve can realize direct-acting type control of the solenoid valve with larger diameter in more economic electromagnet range.
Description
Technical field
The present invention relates to the solenoid valve of application in the automation control, particularly relate 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 problem to be solved in the present invention, 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.
Advantage of the present invention is:
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.
