Abstract
The utility model provides a micro power consumption electric switch valve which is composed of a magnetic push rod. Three magnet steels are respectively installed on a valve core and a disc which is driven by a micro motor. When the micro motor is returned and rotated to a position, the pushing functions of the magnetic steels are used for changing the rotation of the micro motor into the reciprocating movement of the valve core. Thereby, the start and the stop of a valve door can be realized. The utility model has the advantages of full seal, no leakage, pulse switch, micro power consumption and simple structure, is suitable for the control of the start and the stop of various types of liquid and gases, is suitable for the guide control of the valve door, and is particularly suitable for battery powered places.
Description
The utility model is a kind of valve by micro motor controlling liquid switch, and its driving power consumption is very little, is specially adapted to the powered battery place.
Existing electric valve is made up of valve body, spool, push rod, eccentric cam mechanism, reduction gear, realizes the switch control of valve by motor rotating band movable eccentric wheel, push rod to-and-fro motion.The problem that this class valve exists is: push rod one side to-and-fro motion neatly promotes the switching spool valve, simultaneously in order to stop along push rod shaft to leakage liquid, to rubber seal be set in the cooperation place of push rod and valve body, so just strengthen the push rod resistance, increased the power consumption of drive motor, when the working pressure of valve is high more, the surface friction drag between Sealing and the push rod is also big more, the wearing and tearing of rubber seal simultaneously, the aging leakage that will cause valve make defective valve.
Leak in order to solve push rod, the water valve of certain structures is fixed one bowl of type rubber on push rod, can solve the push rod place like this and leak, but this rubber cup, and push rod moves that not only resistance is bigger, and the rubber cup life-span is very short, so application places is restricted.
The purpose of this utility model is that a kind of no push rod will be provided, valve insertion and driving mechanism are isolated fully, utilize magnetic material " same sex is repelled each other, there is a natural attraction between the sexes " principle to promote the on-off action that the spool to-and-fro motion reaches valve, this has just solved the problem that leaks of valve fully, do not have push rod, surface friction drag very little, greatly reduced the power consumption of drive motor.
The purpose of this utility model is to realize like this; At the sealing cover center blind hole is arranged, spool is housed in the blind hole, at the magnet steel of setting-in N utmost point in the upper end of spool over against the blind hole top.The sealing cover of non-magnet material is connected with valve body, forms the inclusion seal chamber.In the sealing cover outer end, magnet steel on spool is installed a disk, on a R of disk end face, two the opposite circular magnet steel of two magnetic poles of 90 ° of setting-ins of being separated by, disk is fixed on the motor rotation axis, when this position will make disk rotate, magnet steel on the magnet steel centrally aligned spool on the disk, such structure has just formed two pairs of touchless magnetic push rods, when rotating as disk on it N utmost point magnet steel aim at magnet steel on the spool, by the same sex effect of repelling each other, spool is subjected to the thrust close port.Opposite spool is subjected to suction and opens valve port, this by the effect of magnetic push rod, has become moving back and forth of spool just the rotation of disk, to reach the effect of switch valve neatly, the control of the angle of 90 ° in disk is to be controlled by the spline pin that inserts in the disk breach in addition.
The utility model had both solved the driving force of spool by the effect of two pairs of magnetic push rods, had overcome the leakage of valve again.Because magnetic push rod zerofriction force makes the drive motor electric current drop to 15mA by 600mA, the dynamic driving power when the spool Open valve only needs 150 grams.Because the switch of valve is to be rotated by the driven by motor disk, use the spool to-and-fro motion to form by the effect of magnetic push rod,, just can obtain the different switching frequencies of valve as long as change the rotating speed of drive motor, to reach the purpose of flow control, also just enlarged the function of valve.Owing to save sealing material, cam, slide-block mechanism, simplified the driving mechanism of valve, make the structure of valve and processing simple, the all-sealed structure of whole valve more helps controlling some and is with corrosive liquid, has enlarged the application places of valve.
The concrete structure of model utility is provided by following examples and accompanying drawing thereof.
Figure is the sectional drawing according to the micro power consumption electric valve that the utility model proposes.
Below in conjunction with details and the working condition of figure detailed description according to the concrete valve that the utility model proposes.
This valve is by valve body (1), spool (10), magnet steel (4), (5), (9), and disk (3), sealing cover (2), installation sleeve (7), spline pin (8), motor (6) are formed.Opened one greater than 90 ° breach in a side of disk (3), insert a spline pin (8) that is fixed on the installation sleeve (7) in the breach, motor (6) adds when 90 ° of spline pins (8) of running in disk (3) breach are rotated in an assurance, magnet steel (4) the S utmost point above the disk (3) faces the N utmost point of the magnet steel (9) on the spool (10) across sealing cover (2), because the sucking action of magnet steel, spool (10) is gone up and is moved, and valve port is opened, and liquid flows out by the diagram direction of arrow.Otherwise give motor (6) inversion pulse.Disk (3) rotates 90 ° in the opposite direction, and by behind spline pin (8) location, the thrust that another magnet steel (5) N above the disk (3) extremely produces the N utmost point of the magnet steel (9) on the spool (10) makes mobile close port under the spool (10).
Claims (1)
- A kind of micro power consumption electric valve, valve body (1) connects sealing cover (2), installation sleeve (7), disk (3), motor (6) to going up down,Its feature has been fixed a disk (3) on motor (6) axle, opened one greater than 90 ° breach in a side of this dish, in breach, insert a spline pin (8) that is fixed on the installation sleeve (7), on the circle that the opposite side of this disk is R with a radius, the be separated by 90 ° of setting-ins opposite circular magnet steel (4) of two magnetic poles, the central blind hole that (5) magnet steel (4) faces sealing cover (2); Spool (10) is housed, thereon N utmost point of end setting-in magnet steel (9) up in the hole.
