The utility model relates to valve, especially solenoid valve.
Background technique
Chinese patent CN02259692.5 discloses a kind of normally open solenoid valve, comprise valve body, valve gap, spool and Returnning spring, the valve body two ends are provided with water-inlet cavity and the water chamber that is communicated with by valve seat, this valve seat i.e. a water-guiding hole, be provided with separation sleeve in the valve gap, be provided with electromagnetic coil between separation sleeve and the valve gap, valve gap is also done the coil case that electromagnetic coil conducts simultaneously, which is provided with the conductive pieces of electromagnetic coil, be provided with static iron core and movable core in the inner chamber of separation sleeve, the leading role of movable core of having held concurrently of this inner chamber, be provided with Returnning spring between valve body and the separation sleeve, spool, movable core is connected by the push rod that is arranged in static iron core with spool, after the electromagnetic coil energising of valve, movable core can drive push rod and spool is descending, the valve seat that presses valve is with throttle down, after the electromagnetic coil outage, pressure by Returnning spring and medium is upwards pushed spool open, this type of solenoid valve, because static iron core is set, make electromagnetic coil after energising, not only make movable core produce active force, static iron core is produced and movable core direction opposite effect power, valve closing starts effect and is affected, requirement to coil is very high, the cost of production of valve is increased, processing technology is complicated, in addition, Returnning spring is located between valve body and the separation sleeve and not and locatees, and can make moving up and down of spool produce skew, influence the closure effect and the working life of valve, and spool is directly to conflict on separation sleeve, this just make spool when resetting and separation sleeve touch, in the course of time, spool will produce loosening even distortion, come off, have influence on the operational effect of whole valve.
Summary of the invention
For solving the deficiencies in the prior art, the utility model provides a kind of more reasonable structure, the normally open solenoid valve of better reset effect is arranged.
For achieving the above object, a kind of normally open solenoid valve that the utility model provides, comprise valve gap, valve body, spool and reset components, the valve body two ends are provided with water-inlet cavity and the water chamber that is communicated with by valve seat, be provided with separation sleeve in the valve gap, be provided with electromagnetic coil between separation sleeve and the valve gap, the preferred coil case that conducts usefulness simultaneously as electromagnetic coil of valve gap, conductive pieces is set on it, be provided with movable core and push rod in the inner chamber of separation sleeve, push rod is preferably plastic material, push rod one end and movable core are conflicted, the other end and spool are fixed, spool is preferably silicon particle, be characterized in that reset components is located between movable core and the spool, cooperate with push rod, reset components spool one end is fixed, the other end and movable core interlock, movable core preferably is arranged on intracavity bottom, and the end face of spool valve seat one side flushes with separation sleeve inner chamber accent or a little in inner chamber accent the inside a bit, this installation that helps the valve miscellaneous part cooperates, like this by change to the reset components position, be arranged in the inner chamber of separation sleeve, reset components is by push rod and movable core and spool interlock, just make reset components when resetting, also can be subjected to separation sleeve inner chamber guiding, can not make the reset generation skew of spool moving, cancelled the setting of original static iron core in addition, movable core can better be moved, reduced the job requirement of valve to electromagnetic coil, and realized the making full use of of the original volume of separation sleeve inner chamber saved the production material of solenoid valve to greatest extent, saved cost, and it is compact that each part is cooperated, and optimizes the operational effect of whole valve.
The preferred reset components of the utility model is a spring, spring spool one end conflict with the fixing positioning seat of separation sleeve internal chamber wall on, the positioning seat preferred material is plastics or similar non-conductive permeability magnetic material, the spool one end outer diameter of positioning seat is slightly larger than the diameter of separation sleeve inner chamber, and this end outer surface is made as a slight ramp and is beneficial to install, this can be installed into the separation sleeve inner chamber by the miniature deformation of plastic material with regard to making positioning seat, and by the extruding contact internal chamber wall that self expands, be fixed in the separation sleeve inner chamber, positioning seat is provided with guide through hole, be sheathed on the push rod with spring, push rod is provided with flange and the spring the other end is conflicted, conflict by the setting and spring spool one end of positioning seat like this, be that spring can not move near spool one end, but the other end of spring, promptly the end near movable core then can compress with the push rod action when push rod is subjected to movable core to drive operation in the conflict by flange, after the electromagnetic coil outage, then again can be by flange with movable core and valve core reset, the setting of guide through hole is then led for the operation of push rod in addition, this just provides another layer guarantee for resetting of spool, flange preferably is arranged on the push rod end, conflict with movable core, movable core and push rod just have a bigger surface of contact like this, and movable core also just can better drive the push rod operation.
The utility model preferably is set to positioning seat guide through hole inwall and is provided with the shoulder rank, and spring is conflicted on the terrace on shoulder rank.So just spring better can be positioned in the positioning seat, spring can not be recompressed or reseting procedure in moving about not producing, for the operation of spring provides safeguard.
The utility model further is provided with the separation sleeve internal chamber wall and is provided with positioning convex ring and following positioning convex ring, last positioning convex ring and following positioning convex ring be internal chamber wall outstanding slightly with the parts separation sleeve one, it can be a circumference, also can be that plurality of sections is formed, the preferred circumference type of the utility model is to strengthen positioning action, positioning seat one end is provided with shoulder rank, location, the terrace on shoulder rank, location is conflicted on last positioning convex ring, the end face of positioning seat spool one side is conflicted on following positioning convex ring, so just made things convenient for the installation of positioning seat, and positioning seat can transition not compressed into the separation sleeve inner chamber, each parts carry out Design Orientation in just can be well to separation sleeve when the valve global design, optimize the operational effect of each parts, that is to say, positioning seat except periphery by the deformation landscape surface on card also just in time be stuck on the longitudinal surface between positioning convex ring and the following positioning convex ring touching on the separation sleeve internal chamber wall, this has strengthened the fixed effect of positioning seat greatly.
The utility model further is provided with between spool and the positioning seat and is provided with headspace.Spool can not touch with positioning seat in reseting procedure and produces loosening even distortion, come off like this, influences the operational effect of valve.
The beneficial effects of the utility model are by the change that reset components is provided with, to guarantee normally resetting of spool, cancelled the setting of original static iron core again, movable core can better be resetted, and more original more reasonable of the utility model overall structure, cost of production is low, and is stable good.
Below in conjunction with the drawings and specific embodiments the utility model is done further introduction.
