Abstract
The utility model relates to a direct drive type bi-directional electromagnetic valve which adopts a double valve disc pressure balancing sealing structure and comprises a valve body, a valve seat, an upper valve disc, a lower valve disc and a valve rod component. Medium inlet or outlet end openings are arranged at two sides of the valve body, wherein, one end opening is connected and communicated with a middle valve cavity formed inside the valve seat, and the other end opening is connected and communicated with an upper valve cavity and a lower valve cavity formed between the valve seat and the valve body. The upper valve disc and the lower valve disc are arranged respectively at the top end opening and the bottom end opening of the valve seat to form a double sealing surface and thereby form the double valve disc sealing structure, the upper valve disc and the lower valve disc are respectively fixed on the valve rod component, when the medium force is functioned on the upper and the lower valve discs, the valve rod component is under stress of the upward thrusting and the downward pressing medium force to reach balance, thus the the double valve disc pressure balancing sealing structure is formed. The direct drive type bi-directional electromagnetic valve has the advantages that the valve can work in the vacuum condition, and the functions of negative pressure bearing, bi-directional sealing, arbitrary connection of two end openings and the function that the two end openings are taken as inlets alternatively and the non pressure difference working can be realized. Moreover, the direct drive type control of the larger caliber electromagnetic valve can be realized in the range of more economical electric magnet.
Description
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-way solenoid valve.
Background technique
Solenoid valve is the pipe-line system executive component of control automatically, the valve seat of general solenoid valve and the sealing pair that valve disc (or piston) sealing surface has constituted solenoid valve, its sealing force is from ducted medium power and valve inner spring power, the solenoid valve working principle is: produce suction behind electromagnet coil power, overcome spring force and medium power, promote valve disc (or piston) and lose sealing force, realize opening valve or close valve; Suction disappears after the electromagnet coil dead electricity, and then spring force and medium are tried hard to recommend moving valve disc (or piston) recovery sealing force, 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, its seal form has determined the orientation sealing of solenoid valve, promptly MEDIA FLOW according to the rules could realize the function of solenoid valve when using, need pipe-line system to guarantee to have forward pressure reduction to exist, define the Applicable scope of solenoid valve.
Summary of the invention
The technical problems to be solved in the utility model, provide a kind of influence that is not subjected to the MEDIA FLOW pressure and the flow direction, only be subjected to the effect of 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 all can work the direct-acting type two-way solenoid valve of employing bivalve dish pressure balance type sealing configuration having under pressure reduction and the no pressure reduction state.
The technological scheme that adopts is:
Direct-acting type two-way solenoid valve adopts bivalve dish pressure balance type sealing configuration, comprises valve body, upper valve base, lower valve base, last valve disc, following valve disc, valve rod assembly.Described valve body both sides are provided with the port that medium advances or goes out, wherein in a port and the valve seat in the middle of valve pocket be connected and communicate, the uuper valve chamber, the lower valve chamber that form between another port and valve seat and valve body are connected and communicate.Valve disc is upper and lower bivalve dish, last valve disc and following valve disc are contained in respectively on upper valve base and the lower valve base and constitute double-sealing face, form bivalve dish sealing configuration, last valve disc and following valve disc are separately fixed on the valve rod assembly, when the medium masterpiece is used in upper and lower valve disc, can make valve rod assembly be subjected to upwards pushing away and reach balance, constitute the direct-acting type two-way solenoid valve of bivalve dish pressure balance type sealing configuration to the medium power that presses down.
Advantage of the present utility model:
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, in two-position two-way solenoid valve, can realize each end interface, be installed in arbitrarily in the system pipeline, can realize bearing negative pressure, two way sealed, any connection of two-port reach the function that replaces as import.
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.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Direct-acting type two-way solenoid valve adopts bivalve dish pressure balance type sealing configuration, comprises valve body 1, upper valve base 4, lower valve base 11, last valve disc 5, following valve disc 9, valve rod assembly 8.Described valve body 1 both sides are provided with the port 2,7 that medium advances or goes out, wherein in a port 2 and the valve seat in the middle of valve pocket 3 be connected and communicate, the uuper valve chamber 6, the lower valve chamber 10 that form between another port 7 and valve seat and valve body are connected and communicate.Valve disc is upper and lower bivalve dish, and last valve disc 5 and following valve disc 9 are contained in respectively on upper valve base 4 and the lower valve base 11, constitute double-sealing and, last valve disc 5 is separately fixed on the valve rod assembly 8 with following valve disc 9.When medium enters from port one, between upper and lower valve disc, form pressure balance as shown in the figure, just valve disc and valve seat can be sealed reliably and open by iron core deadweight and spring force.Same medium enters from port 7, also can reach identical solenoid valve sealing and unlatching.Can realize bearing negative pressure, two way sealed, any connection of two-port reach the function that replaces as import.
