Practical novel content
The utility model is intended to provide a kind of spring induction type check valve, easily loses efficacy to solve existing check valve spring, and spool snap-in force is not enough, valve closes not problem thoroughly.
Spring induction type check valve in this scheme, spring induction type check valve, comprise valve body, valve body is respectively equipped with first flow and second road, between first flow with second road, it is provided with the valve seat of ring-type and coordinates the spool opened and closed with valve seat, described valve seat is provided with electro-magnet, it is provided with iron block in the end of described spool, described spool is hollow structure, guiding seat it is provided with successively in the cavity of spool, guide rod, spring and slide plate, guiding seat can slide along cavity wall under the effect of hydraulic pressure, chute is had in the inner side of guiding seat, one end of guide pillar is located in chute, spring is positioned at outside guide pillar, and one end of spring is fixed on the end face inside guiding seat, under spring state of nature, distance is there is between the bottom land of chute and the end of guide pillar, valve body is also provided with end cap, installation groove is had in the inner side of described end cap, the other end of guide pillar is fixed on the bottom land installing groove, guide pillar is positioned at installation groove and is provided with the slide plate that can slide along installation groove cell wall, the other end and the slide plate of spring are fixed, the both sides being positioned at slide plate on installation groove are respectively equipped with the first sensing chip and the 2nd sensing chip, first sensing chip and the 2nd sensing chip are respectively used to control energising and the power-off of electro-magnet.
The principle of work of the utility model spring induction type check valve is as follows:
Under spring is in state of nature, the end face of guiding seat is concordant with the end face of spool, and slide plate contacts with the first sensing chip, by the loop energising of the signal of the first sensing chip control electro-magnet, electro-magnet is charged, attracts iron block, the end face of valve seat and spool is fitted tightly, valve closes.
First flow is entered when there being liquid, liquid continuous increase, under the effect of hydraulic pressure, promote the guiding seat in spool cavity along spool axial motion, guiding seat compression spring, by promoting, slide plate moves spring along the cell wall installing groove, when slide plate touches the 2nd sensing chip, by the loop power-off of the signal of the 2nd sensing chip control electro-magnet, electro-magnet power-off, to no longer attract iron block, now, under the effect of hydraulic pressure, valve core movement will be promoted, spool is separated with valve seat, and first flow is connected with second road, valve opening.
When liquid stream is complete, when not continuing the liquid flowed in first flow, hydraulic pressure reduces gradually, and spring recovers state of nature, and slide plate returns to starting position, contacts with the first sensing chip, and electro-magnet is energized, valve closes.
Repeat above-mentioned steps, it may be achieved the reciprocal keying of valve.
In this scheme, owing to being sealing between guiding seat and cavity inwall, therefore liquid can not flow in the cavity of spool.
This scheme is compared to prior art: 1. carry out valve-off by the magnetism of electro-magnet and iron block, even if life-time service, also there will be no the problem of snap-in force deficiency, can guarantee that valve is effectively closed all the time; 2. under spring state of nature, there is distance between the bottom land of chute and the end of guide pillar, both can meet the motion of guiding seat under hydraulic pressure effect, and owing to guide pillar is to the position-limiting action of guiding seat, hydraulic pressure can be prevented again excessive, force guiding seat persistent movement and damage spring by pressure; 3. creativeness by the spring design cost scheme of traditional offer snap-in force play induction deformation effect spring, owing to guide pillar is to the position-limiting action of guiding seat, even if therefore life-time service, the spring of this scheme also can not damage inefficacy, can not affect the work-ing life of whole valve.
Further, between guiding seat and cavity inwall, it is provided with sealing-ring, the distance that the length of described sealing-ring is greater than between the bottom land of chute and guide pillar end. Sealing-ring can anti-fluid enter in the cavity of spool, and the distance that the length of sealing-ring is greater than between the bottom land of chute and guide pillar end, even if ensureing guiding seat in the effect lower slip of hydraulic pressure to maximum position (bottom land of chute and the end of guide pillar offset), liquid also can not enter in cavity.
Further, iron block, in annular, increases the area that iron block is corresponding with electromagnet, increases magnetism.
Further, the end face of valve seat is internal taper face anchor ring, and described spool is the external taper anchor ring that tapering is identical with internal taper anchor ring with the end face of one end that valve seat coordinates. Valve seat and spool are all designed to tapering anchor ring, and during closedown, laminating is tightr, and liquid can not overflow.
Further, end cap is connected with valve body screw thread, installs in groove the axis along end cap and has multiple open holes, and the first sensing chip and the 2nd sensing chip are arranged on wherein in two open holess respectively. End cap is connected not only end cap for convenience detach with valve body screw thread, and when the spring playing influential action declines because of life-time service spring power, easily end cap can be disassembled, first sensing chip and the 2nd sensing chip are arranged in other hole (normally locating distance from more close to), and then load onto end cap, even if spring power decline like this, the stroke of slide plate is affected, and the contact that also can not affect between slide plate with two sensing chips coordinates.
Further, having guide path in described installation groove, the two ends of slide plate are all positioned at guide path. When slide plate is along the axial motion of guide rod, slide plate is had the effect of guiding by guide path.
Further, between slide plate and the bottom land installing groove, it is provided with return spring, passes through return spring, in the process that hydraulic pressure reduces gradually, slide plate can be forced to head on spring, and spring heads on guiding seat makes guiding seat automatically reset, and returns to the position concordant with spool end face.
