Improve as one, the external diameter in described polished rod portion is consistent with the large footpath of described screw section.
As further improvement, between described locking nut and described seal element, be provided with the gland be set in described polished rod portion.
As improving further, described pressure regulation bar is provided with groove near one end of described elastic element again; Described elastic element is constrained in described groove.
As further improving, described pressure regulation bar is provided with force-application block.
Owing to have employed technique scheme, the beneficial effect of a kind of pressure regulator valve provided by the utility model is as follows:
Because pressure regulation bar comprises the screw section being arranged at pressure regulation bar two ends, polished rod portion is provided with between two screw sections, portion is set with seal element with polished rod, thus when assembling, first screw section is screwed in pressure ports, then seal element is set in polished rod portion, finally by locking nut, seal element is closely relied on valve body; During pressure regulation, realized by the difference screwing in pressure ports internal pressure-regulating pole length.Adopt the pressure regulator valve of this structure, by coordinating of seal element and polished rod portion, not only achieve the end face seal between valve body and seal element, and the radial seal achieved between seal element and polished rod portion, effectively prevent the problem that in conventional construction, fluid oozes out along screw thread, simultaneously, structure is simple, be convenient to processing, cost is low, and does not affect normal pressure regulation work.
Due to the external diameter in polished rod portion and the large footpath of screw section consistent, thus achieve the clearing end of screw section and being connected of polished rod portion starting point, reach the object that polished rod portion starting point stops fluid, and then improve leakage proof effect.
Owing to being provided with the gland be set in polished rod portion between locking nut and seal element, thus by the transition of gland between locking nut and seal element, the active force achieved when locking nut screws acts on gland, prevents locking nut to be with moving sealing element rotate and affect sealing effect when screwing.
Because elastic element is constrained in groove, thus realized the location of elastic element by groove, prevent pressure regulation bar from rotating elastic element when installing and rock in pressure ports.
Because pressure regulation bar is provided with force-application block, thus act on force-application block by spanner, be convenient to pressure regulation bar screw thread and be mounted on valve body; Meanwhile, regulate pressure size to lay the foundation for ease of pressure regulation bar, structure is simple, and using effect is good.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Fig. 1 and Fig. 2 jointly shown in, a kind of pressure regulator valve, comprise valve body 1, this valve body 1 is provided with filler opening 10 and pressure ports 11, the upstream of this filler opening 10 is provided with the oil inlet passage 12 be communicated with oil system, and be provided with pressure release passage 13 with the valve body 1 of pressure ports 11 corresponding position, this pressure release passage 13 is communicated with pressure ports 11, be provided with elastic element 2 in this pressure ports 11, this elastic element 2 is preferably Compress Spring.
This valve body 1 is also provided with the pressure regulation bar 3 leaned with elastic element 2, the other end of this elastic element 2 leans the spherical valve core 4 for shutoff filler opening 10, thus when the pressure of valve body 1 is excessive, fluid backs down spool 4 and enters pressure release passage 13 pressure release.
This pressure regulation bar 3 comprises the screw section 31 being arranged at pressure regulation bar 3 two ends, polished rod portion 32 is provided with between two screw sections 31, wherein screw section 31 screw thread is installed in pressure ports 11, in this pressure ports 11, the length of set screw thread is greater than the length of screw section 31, another screw section 31 extend to valve body 1 outside and on it screw thread locking nut 5 is installed.
This pressure regulation bar 3 is also provided with force-application block 34, is specially: this force-application block 34 be arranged at be positioned at valve body 1 outside screw section 31 on, thus to be acted on force-application block 34 by spanner, be convenient to pressure regulation bar 3 screw thread and be mounted on valve body 1; Meanwhile, regulate pressure size to lay the foundation for ease of pressure regulation bar 3, structure is simple, and using effect is good.
The external diameter in this polished rod portion 32 is consistent with the large footpath of screw section 31, thus achieves the clearing end of screw section 31 and being connected of polished rod portion 32 starting point, reaches the object that polished rod portion 32 starting point stops fluid, and then improves leakage proof effect.
Be provided with seal element 6 between this locking nut 5 and valve body 1, sealing element 6 is set in polished rod portion 32, is provided with the gland 7 be set in polished rod portion 32 between this locking nut 5 and seal element 6, and the sectional shape of this gland 7 is " C " type; Thus by the transition of gland 7 between locking nut 5 and seal element 6, the active force achieved when locking nut 5 screws acts directly on gland 7, prevents locking nut 5 to be with moving sealing element 6 rotate and affect sealing effect when screwing.
As preferably, sealing element 6 is rubber gasket, and this rubber gasket and polished rod portion 32 closely cooperate, this gland 7 and polished rod portion 32 Spielpassung.
This pressure regulation bar 3 is provided with groove 33 near one end of elastic element 2; This elastic element 2 is constrained in groove 33, thus realizes the location of elastic element 2 by groove 33, prevents pressure regulation bar 3 from rotating elastic element 2 when installing and rocks in pressure ports 11.
Adopt the pressure regulator valve of this structure, when assembling, first the screw section 31 not arranging force-application block 34 one end is screwed in pressure ports 11, then seal element 6 is set in polished rod portion 32, finally by the mode screwing locking nut 5, seal element 6 is closely relied on valve body 1; During according to requirements of one's work adjustment pressure, only just can need be realized by the difference screwing in pressure ports 11 internal pressure-regulating bar 3 length.
In sum, by coordinating of seal element 6 and polished rod portion 32, not only achieve the end face seal between valve body 1 and seal element 6, and the radial seal achieved between seal element 6 and polished rod portion 32, effectively prevent the problem that in conventional construction, fluid screw thread oozes out, simultaneously, structure is simple, be convenient to processing, cost is low, and does not affect normal pressure regulation work.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
