A thin wall stainless steel pipe is used as a guide pipe and is integrated with a magnetism conducting post by welding, and an electromagnetic coil is coiled by enamelled wires at the outer wall of the stainless steel pipe to improve the electromagnetic efficiency of a device. Insulating plastics are filled among an iron magnetism conducting casing and a permanent magnet, the conducting pipe, the coil, a magnetism conducting plate, etc. to eliminate the probability that the components are damaged by friction due to relative displacement, wherein the magnetism conducting casing is used for sealing a magnetic path and fixing the device and the permanent magnet, the conducting pipe, the coil, the magnetism conducting plate, etc. are contained in the iron magnetism conducting casing. The firmness degree of the device is strengthened, the service life is increased, and electricity-saving effects are increased.
Description
Technical field
The utility model relates to a kind of control water solenoid valve, especially a kind of bistable state control water solenoid valve.
Background technique
Traditional control water solenoid valve is the effect that utilizes the opposite power of two kinds of directions of electromagnetic force and spring force, controls the displacement that is positioned at the conduit inner spool by switching on to electromagnetic coil with dead electricity and comes the break-make current.Bistable state control water solenoid valve has installed conducting magnetic column additional in the upper end of conduit then on this basis, and on the top of conducting magnetic column permanent magnet has been installed, and magnetic conduction shell and magnetic conducting plate are then adorned with closed magnetic path in the outside of electromagnetic coil, in order to improve the electromagnetic efficiency of device.So, all not power consumptions when solenoid valve keeps at the break-make two states, the impulsive current that only needs to impose positive and negative two kinds of different direction in the moment of state exchange gets final product.Therefore, the solenoid valve that this structure is more traditional is energy-conservation significantly, and makes device adopt the low-voltage dc power supply power supply to become a reality.But as the solenoid valve that uses the low-voltage dc power supply power supply, present structure, its electromagnetic efficiency is high not enough, and conduit made of plastic is subject to the effect of mechanical admixture in the water and causes wearing and tearing, influences usability and working life.
Summary of the invention
The purpose of the utility model technical solution problem is in order to improve the electromagnetic efficiency of bistable state control water solenoid valve, to improve its usability, increasing working life.
The technological scheme that the utility model addresses the above problem is:
1. adopting thin-wall stainless steel is conduit, and is connected as a single entity by welding with the stainless iron conducting magnetic column, removes coil carrier, turns to electromagnetic coil at conduit outer wall (or at conduit outer wall earlier every with insulation film) with enameled cable.
2. in Electrical heads, magnetic conductive shell has the function of magnetic confining field and Motionless electromagnetic head position concurrently.Fill with ambroin between the parts such as the permanent magnet that housing and its contained, conduit, electromagnetic coil, magnetic conducting plate, make to be connected firmly between each parts, the Electrical heads bottom is smooth smooth.
The beneficial effects of the utility model are: increased the electromagnetic efficiency of electromagnetic coil, increased the intensity and the wear-resistant ability of conduit; The sealing and firm degree of Electrical heads have been strengthened.Thereby, power savings, usability and the working life of having improved bistable state control water solenoid valve.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further illustrated.
Accompanying drawing is a structural representation of the present utility model.
1. magnetic conduction shells among the figure, 2. permanent magnet, 3. conduit, 4. conducting magnetic column, 5. electromagnetic coil, 6. spool, 7. spring, 8. magnetic conducting plate, 9. rubber leather point, 10. lead-in wire, 11. plastics obturators, 12. floating seats, 13. rubbery membrana dermalis, 14. valve seats, 15. screws.
Embodiment
As shown in the figure, the Electrical heads that bistable state control water solenoid valve is equipped with spring (7), spool (6) and rubber leather point (9) by inside with in the valve seat (14) of floating seat (12) and rubbery membrana dermalis (13) is housed, be formed by connecting by screw (15).
In Electrical heads, magnetic conduction shell (1) has contained miscellaneous part, the top of enclosure interior is connected with permanent magnet (2), permanent magnet (2) then is connected by the conduit (3) that conducting magnetic column (4) and Stainless Steel Tube weld together, the outer wall cover of conduit (3) is with electromagnetic coil (5), electromagnetic coil (5) then connects to mould copper-clad matter lead-in wire (10) and passes magnetic conduction shell (1) and cause outside, then fill up with magnetic conducting plate (8) bottom of electromagnetic coil (5), then fill out with plastics between each parts that magnetic conduction shell (1) is contained in the mode of plastic packaging, make it in conjunction with firm, sealing, the Electrical heads bottom is smooth, smooth.Then adorn in the conduit (3) to connect the spool (6) of rubber leather point (9), install pressure spring (7) in the deep hole on spool (6) top.
When lead-in wire (10) is connected ABAP Adapter, the electromagnetic force of the ascent direction that is produced by electromagnetic coil (5) by the direct impulse electric current makes spool (6) overcome gravity, spring force, the resistance of water etc. moves up and is firmly attracted by the conducting magnetic column (4) that is connected with permanent magnet (2), rubber leather point (9) leaves the pilot hole on the floating seat (12) then and causes current and flow to the water outlet of valve seat (14) from the water intake of valve seat (14) equalizing orifice by floating seat (12) through pilot hole, rubbery membrana dermalis (13) and floating seat (12) are risen and allows current be flowed out through the valve seat water outlet by the water intake of valve seat (14).At this moment, valve open.On the contrary, when additional power source imposes the reverse impulse electric current, the reverse electromagnetic force that produced by electromagnetic coil (5) has been offset permanent magnetism power makes spool (6) leave conducting magnetic column (4) to the sucking action of spool (6), and it is descending under the elastic force effect of spring (7), cause the rubber leather point (9) that is attached thereto tightly to cover pilot hole on the floating seat (12), under the effect of hydraulic pressure, current are descending to lower compression floating seat (12) and rubbery membrana dermalis (13) by the equalizing orifice of floating seat (12), and then cover the water outlet of valve seat (14), blocked flowing of water.At this moment, valve closing.
