Description
Technical field
The utility model relates to a kind of valve, particularly relates to a kind of novel hydraulic one-way valve.
Background technique
One-way valve refers to that the fluid flowed through in one-way valve can only flow from import to Way out, the valve that the fluid in outlet port cannot reflux.When one-way valve uses, carry out forward and lead to liquid, then liquid medium applies active force through the import of body to spool, makes that it overcomes spring force and away from sealing surface, liquid medium flows through spool through the spacing between spool and body sidewall and flows out from the outlet of body.Otherwise spool is resisted against on sealing surface, the liquid medium in outlet port applies active force to spool, spool only can be made to be resisted against to form sealing on sealing surface more closely, anti-backflow.
Hydraulically-controlled one-way valve of the prior art for spool or the stroke of valve rod and the restriction of braking few, the operating pressure for valve body is difficult to control, and makes valve body be difficult to affect the working life be applied in tight equipment and for valve body.
Model utility content
For the present situation of above-mentioned prior art, it is simple that technical problem to be solved in the utility model is to provide a kind of structure, and it is convenient to load and unload, and controls closely, the novel hydraulic one-way valve of long service life for valve body operating pressure.
The utility model solves the problems of the technologies described above adopted technological scheme: a kind of novel hydraulic one-way valve, comprise valve body, described valve body is detachably connected with piston sleeve, oil inlet pipe is provided with in described valve body, oil inlet hole is had in described piston sleeve, this oil inlet pipe is connected with oil inlet hole, piston is provided with in described piston sleeve, valve rod and valve rod spring is worn in this piston, and this valve rod runs through valve body, this piston can lean with piston sleeve face and be formed and seal under the effect of the elastic force of valve rod spring, described valve rod is equipped with moveable flange, this valve rod one end is expanded and wears stop ring, this expand end with the spacing flange of stop ring in it between the two.
Further, described valve rod one end cover has spring seat, is provided with piston spring, more the sealing of valve body and the reset capability of valve rod between this spring seat and piston.
Further, be provided with jump ring between described spring seat and valve rod, this jump ring is for connecting valve rod and spring seat.
Further, described piston sleeve is connected with valve body by hex screw, is convenient to handling.
Compared with prior art, the utility model has the advantage of: the utility model compact structure, piston sleeve and valve body are for removably connecting, be convenient to user's installation and maintenance, by oil inlet hole, pressure is produced to piston at hydraulic oil, piston overpowers spring resistance is moved right, band ovable valve stem moves, the stroke of valve rod is limited because stop ring and flange offset, during draining, spring band ovable valve stem resets, because the end that expands of valve rod offsets limit the stroke of valve rod with flange, make the control of valve body for oil pressure in work process more accurate, increase the long service life of valve body, suitable large-scale promotion.
Accompanying drawing explanation
Fig. 1 is partial sectional view of the present utility model.
Embodiment
As shown in Figure 1, a kind of novel hydraulic one-way valve, comprise valve body 1, described valve body 1 is detachably connected with piston sleeve 2, preferably, for the ease of handling maintenance, the both sides of described piston sleeve 2 are connected with valve body 1 by hex screw, oil inlet pipe 3 is had in described valve body 1, oil inlet hole 4 is had in piston sleeve 2, this oil inlet pipe 3 is connected with oil inlet hole 4, piston 5 is provided with in described piston sleeve 2, valve rod 9 and valve rod spring 8 is worn in this piston 5, and the right-hand member of this valve rod 9 runs through valve body 1, this piston 3 can lean with piston sleeve 2 face and be formed and seal under the effect of the elastic force of valve rod spring 8, preferably, in order to the reset capability of the sealing and valve rod 9 that increase valve body 1, the left end cover of described valve rod 9 has spring seat 7, piston spring 6 is provided with between this spring seat 7 and piston 5, and be connected by jump ring between spring seat 7 with valve rod 9, described valve rod 9 is provided with stop ring 10, the right-hand member of this valve rod 9 expands, stop ring 10 and valve rod 9 expand hold between be equipped with moveable flange 11, and this flange 11 is limited in it between the two.
In the course of the work, hydraulic oil is by oil inlet pipe 3 oil-feed, hydraulic oil to be contacted with piston 5 by oil inlet hole 4 and by oil pressure transmission, make piston 5 overcome piston spring 6 to move right with the resistance of valve rod spring 8, and be with ovable valve stem 9 to move, right side due to stop ring and flange offsets and limits the stroke of valve rod 9, during draining, piston spring 6 and valve rod spring 8 are with ovable valve stem 9 to reset, because the end that expands of valve rod 9 to offset with the right side of flange 11 and limits the stroke of valve rod, make the control of valve body 1 for oil pressure in work process more accurate, increase the long service life of valve body, suitable large-scale promotion.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, it will be understood by those of skill in the art that it still can be modified to the technological scheme described in previous embodiment, or wherein portion of techniques feature has been replaced on an equal basis; And these amendments or replacement, do not make the essence of appropriate technical solution depart from spirit and the scope of each embodiment's technological scheme of the utility model.
