Abstract
The invention relates to a direct-acting type two-way solenoid valve which adopts a double valve disc pressure balancing type sealing structure and comprises a valve body, a valve seat, an upper valve disc, a bottom valve disc and a valve rod component. The two sides of the valve body are provided with ports for in or out of the medium; wherein one port is communicated with a middle valve cavity formed in the valve seat and the other port is 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 respectively arranged on a top end port and a bottom end port of the valve seat to form two sealing surfaces so as to further form a double valve disc sealing structure; the upper valve disc and the lower valve disc are respectively fixed on the valve rod component; when being applied to the upper disc and the lower valve disc, the medium force of pushing upward and pressing downward can be applied to the valve rod component to achieve balance so as to form the double valve disc pressure balancing type sealing structure. The solenoid valve can work under the condition of vacuum, realize the functions of bearing negative pressure, two-way sealing, random connection and alternation of the two ports as an inlet, and work without pressure difference. 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-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 problem to be solved in the present invention, 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 invention:
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 invention.
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, constitutes double-sealing face, and last valve disc 5 and following valve disc 9 are separately fixed on the valve rod assembly 8.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.
