Abstract
The utility model relates to an electromagnetic valve, which is composed of a valve body (8), a valve cover (1), a valve disc (4), a valve rod (5), a sealing gasket (7), a press plate (9) of a sealing gasket. The utility model is characterized in that a diaphragm (4) is arranged between the valve cover (1) and the valve body (8), a control cavity is formed between the valve cover (1) and the diaphragm (4), and the inner parts of the valve cover (1) and the valve body (8) are provided with secret passages (10), (13). An electromagnetic valve (11) is arranged on the secret passage (10) from an inlet of the valve to the control cavity, and an electromagnetic valve (12) is arranged on the secret passage (13) of an outlet of the valve and the control cavity. Two small electromagnetic valves are arranged to lead a main valve to be opened, closed, adjusted and locked, and the utility model has the advantages of low cost, convenient use, electricity saving and no running, overflow, dripping and leakage.
Description
Technical field
The utility model relate to a kind ofly open, can close, adjustable, the solenoid valve that can lock.
Background technique
Commercially available solenoid valve has three kinds: direct action solenoid valve, step direct-acting type electromagnetic valve and indirect guide electromagnetic valve, no matter be that a kind of solenoid valve, they can only have out and close two states, the state in the middle of not having out and closing.Existing various electromagnetic valve structures are widely different, and the manufacturing process trouble is not general mutually, the cost height, and particularly bigbore solenoid valve, cost is higher, and power consumption is bigger.Existing solenoid valve generally is to switch on to often opening, and it is normally closed to have a power failure, and not only power consumption in service but also line bag can generate heat, and should not use for occasion moist, high temperature.
Summary of the invention
The purpose of this utility model is to develop and a kind ofly can opens, can close, can transfer, can lock, the solenoid valve of power saving.
Structure of the present utility model is as follows:
It is by valve body, valve gap, valve rod, valve disc, sealing gasket and sealing gasket pressing plate are formed, it is characterized in that valve rod, valve disc, sealing gasket and sealing gasket pressing plate are formed spool, spool is established a barrier film or is had the dividing plate of O type seal ring between the valve body valve gap, spool moves up and down under barrier film or spacer function, between described barrier film or dividing plate and valve body, form a control chamber, between snout cavity and control chamber, help secretly, an inlet direct action solenoid valve on helping secretly, this is arranged, between outlet plenum and control chamber, help secretly, the direct action solenoid valve of an outlet is arranged on this passage; Regulate the size of control chamber pressure with the switch of above-mentioned two solenoid valves.When inlet solenoid valve pass, outlet valve opening solenoid, main valve is opened; When inlet valve opening solenoid, outlet solenoid valve pass, main valve closes; When main valve closes and inlet and outlet solenoid valve when also closing, open and export solenoid valve and close it (being pulse switch) immediately, then main valve is opened a bit, so the aperture of the repeated multiple times requirement that can reach; Open and entrance and exit solenoid valve when closing when main valve, drive a lower inlet solenoid valve and close it immediately, main valve closes a bit, repeated multiple times like this, the pass degree of the requirement that can reach.
The coating that anticorrosion antiwear is arranged inside and outside the valve of the present utility model.
Obviously, advantage is as follows:
1, solenoid valve of the present utility model can be opened, can close, can transfer, can lock.
2, not evaporating, emitting, dripping or leaking of liquid or gas and anticorrosion antiwear.
3,, can reduce greatly and make and sales cost with big main valve of two little electromagnetic valve.
4, main valve is locked on certain switch degree, and little solenoid valve is cold in the long-time running process, and just at logical electricity once of the moment of regulating, thus, power consumption is almost nil.This has not only economized the electricity charge, and the coil of solenoid valve can not generate heat yet, so after coil solidifies sealing with insulating resin, can moisture proof, anti-short circuit.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 does not have the structural representation of spring and valve rod for the utility model main valve;
Fig. 3 is the structural representation of dividing plate for the utility model main valve;
As shown in the figure, 1 is valve gap, and 2 is spring, 3 is the barrier film pressing plate, and 4 is barrier film, and 5 is valve rod, 6 is valve disc, and 7 is sealing gasket, and 8 is valve body, 9 for having the sealing gasket pressing plate of guide fin, 10 is helping secretly of valve inlet and control chamber, and 11 is valve inlet control two-way electromagnetic valve, and 12 is valve export control two-way electromagnetic valve, 13 is helping secretly of valve export and control chamber, and 15 for being with the dividing plate of " O " V-shaped ring.
Constitute main valve by valve gap 1, spring 2, barrier film pressing plate 3, barrier film 4, valve rod 5, valve disc 6, sealing gasket 7, valve body 8 and the sealing gasket pressing plate 9 that has a guide fin.
P1 is an entrance cavity pressure, and P2 is an outlet plenum pressure, and P3 is a control chamber pressure, and barrier film 4 or dividing plate 15 separate valve gap 1 and valve body 8, and it and valve gap 1 form a control chamber.Valve rod 5 holds together barrier film pressing plate 3, barrier film 4 or dividing plate 15, valve disc 6, sealing gasket 7 and sealing gasket pressing plate 9.Valve rod 5 inserts the pilot hole on valve gap 1 top, and the fin of sealing gasket pressing plate 9 inserts valve opening, in the middle guiding that moves up and down.Secret tunnel 10 is communicated with valve inlet with control chamber, secret tunnel 13 is communicated with valve outlet port with control chamber, valve 11 control secret tunnels 10, valve 12 control secret tunnels 13.
Embodiment
Embodiment 1
As shown in Figure 1, it is by valve gap 1, spring 2, barrier film pressing plate, and 3, barrier film 4, valve rod 5, valve disc 6, sealing gasket 7, valve body 8, sealing gasket pressing plate 9, secret tunnel 10, solenoid valve 11, solenoid valve 12, secret tunnel 13 constitute.
Only switch on valve 11 until the main valve complete shut-down, outage, main valve is locked in closed condition; The valve 12 of only switching on, until the main valve standard-sized sheet, outage, main valve is locked in full-gear; When the main valve complete shut-down, and valve 11 and 12 whens outage, pulse electrifying valve 12, locking has a power failure after main valve reaches certain aperture; When main valve is full-gear, and valve 11 and 12 whens outage, pulse dashes energising valve 11, and locking has a power failure after main valve reaches certain pass degree.
