Description
Technical field
The present invention relates to one-way valve technology, be specifically related to a kind of spring induction type one-way valve.
Background technique
One-way valve is also known as safety check or check valve.For preventing oil stream reverse flow in hydraulic system, or for preventing pressurized air reverse flow in pneumatic system.The main structure of existing one-way valve comprises valve body, it is step-like fluid passage that valve body has longitudinal section, valve seat is provided with at the ladder place of fluid passage, valve seat is towards the fluid passage of the larger side of diameter, be provided with in the fluid passage of the larger side of diameter and can coordinate the spool opening and closing fluid passage with valve seat, wherein, during pathway closure, the impacting force that spool compresses valve seat is provided by spring, this traditional one-way valve structures Problems existing is: Long-Time Service, spring easily lost efficacy, cause spool throttle down not thorough, liquid easily overflows in opposite side passage from a side canal, one-way valve partial failure.
Summary of the invention
The invention is intended to provide a kind of spring induction type one-way valve, easily lost efficacy to solve existing check valve spring, spool impacting force is not enough, the halfway problem of valve closing.
Spring induction type one-way valve in this programme, spring induction type one-way valve, comprise valve body, valve body is respectively equipped with first flow and the second runner, between first flow with the second runner, be provided with the valve seat of ring-type and coordinate the spool opened and closed with valve seat, described valve seat is provided with electromagnet, iron block is provided with in the end of described spool, described spool is hollow structure, guide holder is provided with successively in the cavity of spool, guide rod, spring and slide plate, guide holder can slide along cavity wall under the effect of hydraulic pressure, chute is had in the inner side of guide holder, 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 guide holder, under spring 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, mounting groove is had in the inner side of described end cap, the other end of guide pillar is fixed on the bottom land of mounting groove, guide pillar is positioned at mounting groove and is provided with the slide plate that can slide along mounting groove cell wall, the other end and the slide plate of spring are fixed, the both sides that mounting groove is positioned at slide plate are respectively equipped with the first induction piece and the second induction piece, first induction piece and the second induction piece are respectively used to the energising and the power-off that control electromagnet.
The working principle of spring induction type one-way valve of the present invention is as follows:
Spring in the raw under, the end face of guide holder is concordant with the end face of spool, and slide plate contacts with the first induction piece, be energized by the loop of the SC sigmal control electromagnet of the first induction piece, electromagnet is charged, attracts iron block, the end face of valve seat and spool is fitted tightly, valve closing.
First flow is entered when there being liquid, liquid continuously to increase, under the effect of hydraulic pressure, guide holder in promotion spool cavity is along spool axial motion, guide holder Compress Spring, spring moves promoting the cell wall of slide plate along mounting groove, when slide plate touches the second induction piece, by the loop power-off of the SC sigmal control electromagnet of the second induction piece, electromagnet power-off, no longer will attract iron block, now, under the effect of hydraulic pressure, valve core movement will be promoted, spool is separated, first flow and the second flow passage, valve opening with valve seat.
When liquid stream is complete, when not continuing the liquid flowed in first flow, hydraulic pressure reduces gradually, and spring recovers nature, and slide plate returns to initial position, contacts with the first induction piece, and electromagnet is energized, valve closing.
Repeat above-mentioned steps, the reciprocal keying of valve can be realized.
In this programme, owing to being sealing between guide holder and cavity inner wall, therefore liquid can not flow in the cavity of spool.
This programme is compared to prior art: 1. carry out throttle down by the attraction force of electromagnet and iron block, even if Long-Time Service, also can not exist and compress hypodynamic problem, can guarantee that valve is effectively closed all the time; 2. under spring nature, there is distance between the bottom land of chute and the end of guide pillar, both can meet the motion of guide holder under hydraulic pressure, and because guide pillar is to the position-limiting action of guide holder, hydraulic pressure can be prevented again excessive, force guide holder persistent movement and damage spring by pressure; 3. creationary by traditional spring playing induction deformation effect providing the spring design cost approach of impacting force, because guide pillar is to the position-limiting action of guide holder, even if therefore Long-Time Service, the spring of this programme also can not damage inefficacy, can not affect the working life of whole valve.
Further, between guide holder and cavity inner wall, be provided with seal ring, the length of described seal ring is greater than the distance between the bottom land of chute and guide pillar end.Seal ring can anti-fluid enter in the cavity of spool, and the length of seal ring is greater than the distance between the bottom land of chute and guide pillar end, even if ensure that the effect lower slider of guide holder at hydraulic pressure is to maximum position (bottom land of chute and the end of guide pillar offset), liquid also can not enter in cavity.
Further, iron block ringwise, increases the area that iron block is corresponding with electromagnet, increases attraction force.
Further, the end face of valve seat is inner taper face anchor ring, and described spool and the end face of one end that valve seat coordinates are the external taper anchor ring that tapering is identical with inner taper anchor ring.Valve seat and spool are all designed to tapering anchor ring, and that fits during closedown is tightr, and liquid can not overflow.
Further, end cap is connected with valve body screw thread, and the axis along end cap in mounting groove has multiple mounting hole, and the first induction piece and the second induction piece are arranged on wherein in two mounting holes respectively.End cap is connected not only end cap for convenience detach with valve body screw thread, and when the spring playing induced action declines because of Long-Time Service spring force, easily end cap can be disassembled, first induction piece and the second induction piece are arranged on (normally mounting distance is nearer) in other hole, and then load onto end cap, even if spring force declines like this, the stroke of slide plate is affected, and the contact that also can not affect between slide plate with two induction pieces coordinates.
Further, in described mounting groove, have guiding groove, the two ends of slide plate are all positioned at guiding groove.When slide plate is along the axial motion of guide rod, guiding groove has the effect of guiding to slide plate.
Further, between slide plate and the bottom land of mounting groove, be provided with Returnning spring, pass through Returnning spring, in the process that hydraulic pressure reduces gradually, slide plate can be forced to head on spring, and spring heads on guide holder makes guide holder automatically reset, and returns to the position concordant with spool end.
