Embodiment
Specific embodiment of the utility model, referring to figs. 1 through Fig. 4, a kind of magnetic pressure-limit valve comprises water outlet body 1, water inlet body 2, spool 3, magnetic valve pocket 4 and magnetic rings 5 etc.Described water outlet body 1 and water inlet body 2 involutory connections of sealing, and the middle part forms an inner chamber 11, described spool 3 is positioned at this inner chamber 11 in conjunction with magnetic rings 5 and magnetic valve pocket 4, this spool 3 can with inner chamber 11 in move axially.
Wherein, described water outlet body 1 has the water outlet 12 of a communication with cavity 11, can be communicated to watering equipment.
Described water inlet body 1 one ends have water intake 21, the other end has a dividing plate 22, be provided with the through hole 23 that is communicated with water intake 21 and inner chamber 11 by side-walls on this dividing plate 22, be provided with groove 24 in one side towards inner chamber 11, be provided with pad 25 in it, the top correspondence of the position of this groove 24 and size and spool 3 axial regions.When pad 25 can prevent that spool 3 axial regions from moving dividing plate 22 is caused damage.
Described spool 3 has bigger end of a diameter 31 and the less axial region 32 of a diameter, makes spool 3 ends 31 axially be subjected to the hydraulic pressure area greater than axial region 32, axially connects a through hole 33 in the spool.End 31 side wall rings of this spool 3 are established an annular groove 34, establish seal ring 6 in it, and by this, the end 31 of this spool 3 cooperates with the inner wall sealing of inner chamber 11.The end 31 of this spool 3 also is provided with pad 35 on the end face of water outlet 12, the 31 pairs of water outlet bodies 1 in its end caused damage when this pad 35 can prevent that spool 3 from moving axially.The axial region 32 of this spool 3 and dividing plate 22 tools one determining deviation of water inlet body 2, this spacing forms a flow channel 13.
These magnetic valve pocket 4 sealings are located in the inner chamber 11, and the sidewall of inner chamber 11 is provided with a step 26, and this magnetic valve pocket 4 is connected on this step 26, can not move right by this.Be sealed and matched by seal ring 7 between this magnetic valve pocket 4 and the inner chamber 11, and be sealed and matched by seal ring 8 between the axial region 32 of spool 3.
This magnetic rings 5 is socketed on the end of the axial region 32 of spool 3 by end 31, and the magnetic pole of this magnetic rings 5 to be that homopolarity is relative with the magnetic pole of magnetic sliding sleeve 4 arrange.
Working principle of the present utility model is as follows: as shown in Figure 1, when the intake pressure of water inlet body 2 water intakes 21 during less than setting value, this moment, the spool 3 of pressure-limit valve was motionless, water enters the flow channel 13 of inner chamber 11 from water intake 21 via through holes 23 of water inlet body 2, is communicated to the water outlet 12 of water outlet body 1 by the through hole 33 of spool 3; As shown in Figure 2, when the intake pressure of water inlet body 2 water intakes 21 during greater than setting value, water is flowed out by the through hole 33 of spool 3 and acts on the bigger end 31 of spool 3 diameters, spool 3 is moved to the direction of water inlet body 2 under the effect of hydraulic pressure, seal flow channel 13 gradually, reduce inflow, thereby reduce the hydraulic pressure of water outlet body 1 water outlet 12, realize the effect of pressure limiting; And when water outlet body 1 water outlet 12 was plugged, spool 3 further changed 2 flow channels 13 that move until complete closed inner chamber 11 to sending out under the effect of hydraulic pressure, and then reached the effect of high discharge pressure of restriction.
When the water flow of water inlet valve body 2 water intakes 21 was begun to reduce by high pressure, hydraulic pressure reduced the active force to the right of spool 3, because the homopolar-repulsion principle, magnetic valve pocket 4 acts on magnetic rings 5, promotion magnetic rings 5 is moved to the left, thereby spool 3 is moved to the left, and finishes to reset.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
