Abstract

The utility model relates to the industrial valve field and provides a pulse trigger energy-saving electromagnetic valve which is provided with two structures of direct drive type and pilot type. The common characteristic of the two types is that the principle of same repellency and opposite attraction is used to open or close the valve. When the magnet fields are mutually attracted, a valve core is self-attracted to a valve rod, the valve door is opened, the disconnection of the electricity is started; when the magnet fields are mutually expelled, the valve core self-attracted on the valve rod is made an elastic movement downward to push a diaphragm to press on a valve seat, the valve door is closed, the disconnection of the electricity is closed. The different points lie in that a diaphragm spring, a spring seat, a diaphragm seat and the diaphragm of the pilot type structure are arranged on the side of the copper valve body. The valve can match with IC cards and is an ideal electromagnetic valve.

Description

The pulse triggering energy-saving electromagnetic valve

The utility model relates to industrial valve field, is a kind of by the pulse triggering energy-saving electromagnetic valve.

At present, the kind of valve is a lot, the valve of manual unlatching is arranged, closing, and the automatic control electromagnetic valve of multi-functional position etc., the former operation is effort comparatively, and latter's majority is by motivational drive, and can not play self-locking action.But utilize NdFeB material as induction field, trigger to be started valve opening or closed by electric pulse, the solenoid valve with certain energy-saving effect is rarely known by the people.

The purpose of this utility model is, provides a kind of structure design comparatively compact to related domain, and function distribution is the pulse triggering energy-saving electromagnetic valve comparatively reasonably, it can be driven under low voltage, low current conditions, and can carry out self-locking.

Above-mentioned purpose be achieved in that it with direct current as the power that starts valve opening or close, pressing is driven the valve button when driving valve, electric current is inhaled mutually by the neodymium iron boron magnetic field that is provided with on the magnetic field of opening valve coil and producing and the spool, and the spool valve that moves up is opened.Pressing closes the valve button when closing, and repelling each other in the neodymium iron boron magnetic field that is provided with on magnetic field that electric current produced and the spool, makes spool move down valve and be closed.And the operating time of driving valve at every turn or closing valve only finishes in 0.5 second, at ordinary times can not electricity consumption, and than general solenoid valve little power consumption manyfold.Therefore, be an energy-saving electromagnetic valve.

This solenoid valve can with the supporting use of IC-card, help the standardized management with gas, water or other medium.

Referring now to above schematic representation, its feature is further described: Fig. 1, pulse triggering energy-saving electromagnetic valve shown in Figure 2 is by the coil stationary cap, coil-induced shell, the coil outlet box, the diaphragm lid, valve body, coil, valve rod, valve core spring, neodymium iron boron, spool, the diaphragm extension spring, diaphragm, valve seats etc. are formed direct-acting type pulse triggering energy-saving electromagnetic valve, it is characterized in that being provided with coil rack 12 in the coil-induced shell 3, coil 13, be with on the valve rod 14 coil-induced on inserted sheet 11, on the axis below the valve rod 14, be respectively equipped with valve core spring 15, neodymium iron boron 16, spool 17, coil-induced inserted sheet 18 down, seal spool spare 19; Between valve seat 25 and diaphragm seat 22, be provided with diaphragm 23, offer several spileholes 24 in the diaphragm, be provided with diaphragm inlet hole 21, be with diaphragm extension spring 20 in the underpart of spool 17 in the center portion of diaphragm seat 22.

Fig. 3, pulse triggering energy-saving electromagnetic valve shown in Figure 4 are by the coil stationary cap, induction shell, membrane cover, copper valve body, coil, valve rod, valve core spring, neodymium iron boron, spool, diaphragm, valve core spring seat etc. are formed guiding pulse triggering energy-saving electromagnetic valve, the axis that it is characterized in that valve rod 35 belows is provided with valve core spring seat 43, valve core spring 44, and valve nozzle pore 50 is elongated poroid being located in the copper valve body 29; Diaphragm spring 39, spring seat 40, diaphragm seat 41, sheet film 42 are the sides that place copper valve body 29.

Working principle: when not switching on, valve core spring 15 promotes spool 17 downwards, is pressed on the diaphragm inlet hole 21.Gas by diaphragm spilehole 24, all is pressed gas from the valve body inlet hole on the diaphragm, because the pressure difference relation is pressed on diaphragm on the valve seat 25, does not export so the valve body air outlet hole has gas.

Drive valve: when direct current when opening valve coil, it is opposite with neodymium iron boron magnetic field on the spool that coil 13 produces magnetic fields, repels each other according to the dc electromagnetic field same sex, the principle of opposite sex attraction spool is upwards inhaled.Fraction gas is discharged the valve body air outlet hole earlier by the diaphragm inlet hole.At this moment, the valve body suction pressure with go out atmospheric pressure and differ very little, simultaneously, the spool band diaphragm extension spring 20, diaphragm is upwards drawn, all gas is discharged the valve body air outlet hole from valve seat, valve is opened fully.After the outage, be contained in ndfeb magnet suction on the spool than valve core spring resilient beam, also because the gas pressure effect, the spool self-priming is on valve rod 14, and the valve that no matter how cuts off the power supply is for a long time also opened always, and whole process is only finished in 0.5 second.

Close valve: when direct current passed through to close valve coil, coil produced the downward bullet of magnetic field identical with the neodymium iron boron magnetic field on the spool (same sex is repelled each other) spool of self-priming on valve rod and moves, and promotes whole pressing diaphragm on valve seat, and gas can't be discharged, and valve is closed dead fully.After the outage, be contained in neodymium iron boron magnetic attraction on the spool than spool, spring force a little less than, because the gas pressure effect, spool can not inhaled on valve rod more yet, the valve that no matter how cuts off the power supply is for a long time also closed always, whole process is only finished in 0.5 second.Therefore, the solenoid valve of above-mentioned two kinds of structures all has the effect of self-locking.Described VDC DC3.6V is a kind of specification in the coil, also can be made into DC2V, 6V, until different size coils such as 380V, the easy more driving valve working of the high more coil of voltage.

More than owing to adopt ndfeb magnet, so the few power consumption manyfold of the general electromagnetic valve current of current ratio when opening or closing valve.Neodymium iron boron magnetic force and spring force strong with a little less than, be according to the position at spool place and distance relation decision.

Characteristics of energy saving: as long as give 0.5 a second time, VDC DC3.6V valve promptly is opened, and no matter how outage can open for a long time always in self-locking.Give the VDC of 0.5 a second time when closing valve again, valve cuts out, and outage is also closed always.So electric energy has been saved in not electricity consumption at ordinary times, also can be called is to trigger the energy-saving electromagnetic valve immediately.This valve is opened under the DC3.6V low voltage, and the general electromagnetic valve current of current ratio half as large about.Be lower than DC3.6V at power supply, even under the DC2.4V situation, also normal close valve just.This valve can be applied in the facilities such as the running water pipe that has IC-card, hot-water line, gas pipe widely, is a kind of comparatively desirable solenoid valve.
