Abstract
The utility model relates to liquid and gas switch valve field, especially to a micro power consumption electric magnetic control valve, which mainly comprises a valve seat, a valve cover, a water inlet channel, a water outlet channel, a valve stem, two blocks of magnetic steel, a micro motor and a transmission positioning mechanism. One block of the outer magnetic steel is arranged on the top of the valve stem, the other block of the outer magnetic steel is arranged on a sector worm wheel axle and is driven by the micro motor. The two blocks of magnetic steel are arranged on the same axis centre, guaranteeing always facing to each other when rotating, rotational angle of the outer magnetic steel is controlled by the sector worm wheel and a recovery spring in the transmission mechanism. The electric valve is low in power consumption, reliable in performance, simple in structure and good in sealing.
Description
The utility model relates to liquid, gas switch valve field, relates in particular to the electronic magnetic control valve of a kind of little power consumption.
Patent 98228644.9 discloses a kind of " little function mortor operated valve ", it mainly contains valve body, forms into and out of water channel, valve rod, three blocks of magnet steel and micro motor, directly drive the keying that valve is handled in mobile two outer magnet positions with motor, outer magnet is located by the spline tip.Two outer magnets of this mortor operated valve are installed on the disk that drives with motor shaft with eccentric position, so disk requires to have bigger volume, because the effect of magnetic force also is subjected to unbalanced force on the motor shaft, and wearing and tearing easily.Spline tip location also can make motor produce stall, influences working life.In addition, bigger to the power requirements of motor, the also corresponding increase of volume.
The purpose of this utility model is to provide a kind of power consumption little, good airproof performance, the electronic magnetic control valve of little power consumption of long service life.
The utility model is the electronic magnetic control valve of a kind of little power consumption, comprise valve seat, valve gap, valve rod, two blocks of magnet steel, micro motor and transmission positioning means, worm sector and returning spring are housed in the transmission positioning means, are provided with the spline groove between valve rod and the valve gap, simultaneously interior magnet steel is installed on valve stem tip, outer steel is installed on the worm sector axle of valve gap top, and interior magnet steel and outer steel mounting point are in same axle center.Two blocks of magnet steel can adopt symmetrically, opposite polarity a pair of (or many to) magnetic pole.Also can be without monoblock, and opposite polarity magnet steel is combined into any geometrical shape by symmetrical position by some.
After the utility model adopted said structure, its advantage was:
1, simple in structure, volume is little.The switch of control valve only needs motor and simple rotating mechanism, need not special position control device.The internal-external magnetic steel coaxial design makes the counterweight balance on the worm sector axle, can reduce volume, prolongs the working life of driving mechanism.Power requirements to motor is little, and volume is also less relatively.
2, power consumption is little.Only need very little active force during the pilot valve switch on valve rod, the magnetic force between internal-external magnetic steel is very little, rotates the shearing force that overcomes between magnet steel so motor only need drive outer steel.Consumed energy not at ordinary times.
3, reliable operation, shock resistance is good.At close valve state, when pipeline produced vibrations, valve rod can move up and down along amplitude direction.At this moment magnetic force plays the effect that suppresses amplitude, makes valve rod block the epithelium relief hole reliably.Open the valve state, vibrations do not have influence to valve rod.
4, good airproof performance.Come operating valve lever by magnetic force, do not need link between driving mechanism that valve body is outer and valve rod, therefore do not have the sealing part abrasion leakage problem, make valve body that good sealing be arranged.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
Fig. 1 is the utility model overall structure schematic representation;
Fig. 2 is a driving mechanism free state schematic representation described in the utility model;
Fig. 3 opens the valve view for driving mechanism described in the utility model;
Fig. 4 is a driving mechanism close valve state schematic representation described in the utility model;
Fig. 5 is valve rod described in the utility model and valve gap structure for amplifying schematic representation.
The utility model is a kind of little power consumption mortor operated valve, comprise valve seat 2, valve gap 3, valve rod 4, two blocks of magnet steel 5,6, micro motor 8 and transmission positioning means 9 are equipped with worm sector 10 and returning spring 7 in the transmission positioning means 9, be provided with spline groove 16 between valve rod 4 and the valve gap 3, simultaneously magnet steel 5 is installed on valve rod 4 tops, and magnet steel 6 is installed on 10 of the worm sectors of valve gap 3 tops, and interior magnet steel 5 is in same axle center with outer steel 6 mounting points.
The utility model working principle can be discussed by following three aspects:
1, closes valve.When outer steel 6 forwards to interior magnet steel 5 polarity same positions with worm sector 10, the repulsion that valve rod 4 is subjected to magnetic force moves downward, block the relief hole 14 at epithelium pad 11 centers, the high pressure water of water intake 1 enters epithelium 12 epicoeles by the pressurization hole 15 on epithelium pad 11 limits, upper cavity pressure is increased to feed-water end to be equated, so the pressure reduction of epicoele and water outlet 13 presses down epithelium 12, valve is fastened.
2, drive valve.When outer steel 6 forwarded to interior magnet steel 5 polarity opposite location with worm sector 10, the attraction that valve rod 4 is subjected to magnetic force moved upward, and relief hole 14 is opened, and the water of epithelium 12 epicoeles flows out from relief hole 14 rapidly, and upper cavity pressure descends.The pressure reduction that epithelium 12 forms up and down up pushes away epithelium 12, so valve open.
3, driving mechanism.Adopt the worm and gear transmission, worm screw 9 is fixed on the motor shaft, and worm sector 10 drives outer steel by central shaft, and the fan angle of worm sector 10 will guarantee to rotate set angle (at a pair of magnetic pole time be 180 °) under worm screw 9 drives.Worm sector 10 afterbodys are connected with a returning spring 7, and returning spring 7 the other ends are fixed on (accompanying drawing 2) on the housing.Add a forward pulsewidth voltage that enough makes worm sector 10 turn over set angle for motor 8, worm sector 10 forwards to shown in Figure 3 when opening the valve state under motor 8 drives, and just throws off the engagement with worm screw 9, no longer is rotated further.This moment, returning spring 7 was stretched, and after motor 8 stalls, worm sector 10 is in self-locking state, add reverse pulsewidth voltage for motor 8, worm sector 10 meshes with worm screw 9 under returning spring 7 effects again, turns over set angle behind close valve state, disengage from stops operating.When the number of magnetic poles of inside and outside magnet steel 5,6 during greater than 1 pair, set angle is corresponding to be reduced.
