Abstract
The utility model relates to a time-delay electromagnetic valve. The time-delay electromagnetic valve comprises a valve body, a valve core, an inlet and an outlet, wherein the valve core is internally provided with a space for allowing the valve core assembly to move up and down, the valve core assembly comprises an magnet body and an elastic member, the magnet body is coaxially connected in a sliding manner with the elastic member, the elastic member is connected on the upper end of the magnet body, the lower end of the magnet body is also provided with a seal washer, the valve core is internally provided with a medium inlet passage, a medium outflow passage and a connection passage connecting the medium inlet passage with the medium outflow passage, an electrical connection end of the magnet body is also connected with an analogue integrated circuit, and a capacitor in the analogue integrated circuit discharges when the power supply is cut off, thereby realizing delayed closing of the electromagnetic valve. When being powered off, the valve body can still work for a period of time, and then is cut off to return to the closing state. The delayed working time of the electromagnetic valve provided by the utility model can be adjusted as needed, and the electromagnetic valve can be applied to high-pressure gas circuit structures such as a steam mop.
Description
Technical field
The utility model relates to a kind of hardware electro-magnetic time-delay valve device of controlling fluid.
Background technique
Solenoid valve is as widely used a matured product, and technology is also constantly being reformed.As application electromagnetic valve of gas circuit comparatively widely, our specialized designs a normally closed, the high pressure solenoid valve that possesses power-off time delay function, in the time of valve body power-off, valve body still can delay working a period of time, then disconnects, and recovers closed state.This custom-designed solenoid valve delay working time can regulate as required, and applicable to the gas circuit structure of high pressure, as be applied to steam mop etc.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, electro-magnetic time-delay valve is provided, include valve body, spool, entrance and outlet, valve core inside has the space moving up and down for mangetic core assembly, described mangetic core assembly comprises magnet and elastic component, magnet and elastic component slidably coaxially connect, described elastic component is connected in the upper end of magnet, the lower end of magnet is also provided with sealing gasket, in spool, be provided with medium inlet passage, the connecting passage of medium flow pass and connecting media inlet passage and medium flow pass, the power access end of described magnet is also connected with Analogous Integrated Electronic Circuits, capacitor discharge when supply disconnecton in Analogous Integrated Electronic Circuits, realize the time-delay closing of solenoid valve.
Described valve body and elastic component are cylindrical body.
Described valve body and elastic component are installed in a hollow cylindrical body.
The slightly larger in diameter of described sealing gasket is in the diameter of connecting passage.
Described Analogous Integrated Electronic Circuits is installed on valve inner.
The utlity model has following advantage and useful technique effect:
The solenoid valve of the utility model design is compared traditional product: on the one hand, after valve body power-off, can delay working several seconds, delay time can regulate as required; On the one hand, valve body is applicable to high pressure gas circuit structure, and, in elevated pressures situation, valve body can be realized turn-off function, applies more extensive.
Brief description of the drawings
Fig. 1 is valve body structure schematic diagram; Fig. 2 is valve body structure cross-sectional schematic, and Fig. 3 is time delay module circuit diagram.
In above-mentioned figure:
1 is valve body entrance, and 2 is valve outlet, and 3 is valve body power supply lead wire, and 4 is valve body switch control lead-in wire, and 5 is valve body itself, and 6 is coil, and 7 is spring, and 8 is delay circuit module, and 9 is magnet, and 10 is fluid input internal structure, and 11 is fluid output internal structure.
Embodiment
The electro-magnetic time-delay valve of the present embodiment, as shown in Figure 1, structure 1 is valve body entrance to this valve body structure, and 2 is valve outlet, and 3 is valve body power supply lead wire, and 4 is valve body switch control lead-in wire, 5 is valve body itself.
Described time delay module is made up of delay circuit, realizes the time delay of different interval by regulating circuit parameter, and circuit diagram is as Fig. 3, and L1 represents electromagnetic valve body coil, circuit board by with valve body series connection to power supply.
Described this body structure of valve body: shown in Fig. 2,6 is coil, and 8 represent delay circuit module, the valve inner cavity font of falling T metal material cavity, Fig. 2 shows.
Wherein in hollow cylinder 7 be spring, 9 for magnet, 10 for fluid input internal structure, 11 be fluid output internal structure (when valve power-off, magnet relies on acting force of the spring and the fixing sealing gasket of magnet itself that hole 10,11 is sealed, and valve is normally closed).
In the time of electromagnetic valve work, power line 3 is connected, control switch 4 closures, and valve body coil powers on by circuit (Fig. 3), forms electromagnetic field, magnet 9(is in hollow cylinder) and overcome spring 7 resistances, be raised; Fluid, due to pressure own, enters valve body (hollow cylinder) from valve body entrance 10, because magnet is raised, fluid via valve body from exporting 11 outflows; When control switch disconnects, capacitor discharge in delay circuit (Fig. 3) in valve body, make valve body coil continue to power on, by regulating device parameters, regulate delay time, capacitor discharge finishes, coil blackout, magnetic field (in hollow cylinder) disappears, and magnet 9 seals the entrance of valve inner 10, outlet 11 due to the restoring force effect of spring own, now solenoid closure.
Preferably, conventionally understand the sealing gasket that preferred dimension is a bit larger tham connecting passage size, to realize better sealing.
Preferably, for making valve body structure compacter, conventionally Analogous Integrated Electronic Circuits can be arranged on to valve inner, jointly be installed on the inside of valve shell with parts such as spools.
