The utility model discloses an oil adjusting valve. The oil adjusting valve comprises a valve body, a bonnet, a valve stem, a valve element, a valve seat and an actuator, wherein the bonnet is fixed on the valve body; the lower end of the valve stem extends in the valve body and is connected with the valve element; the upper end of the valve stem extends out of the bonnet and is connected with the actuator; the lower end surface of the valve element is sealed with the valve seat arranged in the valve body; a valve element pressure-adjusting moving cavity is formed among the bottom of the bonnet, the upper portion of an inner cavity of the valve body and the top of the valve element in a surrounding manner; a pressure-adjusting nut and a resetting spring are arranged in the valve element pressure-adjusting moving cavity; the lower end of the valve stem sequentially penetrates in the pressure-adjusting nut and the resetting spring; inner threads are arranged on the inner wall of the upper portion of the inner cavity of the valve body; outer threads which are matched with the inner threads are arranged on the outer wall of the pressure-adjusting nut; the upper end of the resetting spring is connected with the pressure-adjusting nut; and the lower end of the resetting spring is connected to the top of the valve element. The valve element moves in the valve element pressure-adjusting moving cavity under the effect of the resetting spring; the purpose of controlling the flow and the pressure is achieved; and the pressure-adjusting capability of the valve element can be changed by the pressure-adjusting nut.
Description
Technical field
The utility model relates to modulating valve field, particularly a kind of oils regulating valve.
Background technique
Current oils regulating valve is mainly taking manual tune as main, once manual tune puts in place, the pressure of its adjusting is fixing, if there is fluctuation in pipe fluid pressure, pressure after its pressure regulation still, for what fluctuate, makes piping flow alter a great deal like this, affects normal oil transportation.
Model utility content
Technical problem to be solved in the utility model is for the deficiencies in the prior art or defect, provides a kind of oils regulating valve that can pressure self-balancing, to address the above problem.
The technical problem that the utility model solves can realize by the following technical solutions:
A kind of oils regulating valve, comprise valve body, valve gap, valve rod, spool, valve seat, actuator, described valve gap is fixed on described valve body, described valve rod lower end is stretched into described valve inner and is connected with described spool, described valve rod upper end is stretched out outside valve gap and is connected with described actuator, the lower end surface of described spool be arranged on the valve base sealing in described valve body, described valve gap bottom, described body cavity top, between described spool top, surround a spool pressure regulation activity chamber, in described spool pressure regulation activity chamber, be provided with look nut and Returnning spring, described valve rod lower end is successively through described look nut and Returnning spring, described body cavity upper inside wall is provided with internal thread, the outer wall of described look nut is provided with the outside thread with described screw-internal thread fit, the upper end of described Returnning spring connects described look nut, the lower end of described Returnning spring connects described spool top.
In a preferred embodiment of the present utility model, described valve rod comprises upper valve rod and lower valve rod, between described upper valve rod and lower valve rod, connect by an elastomer block, the lower end of described lower valve rod is connected with described spool, and the upper end of described upper valve rod is connected with described actuator.
In a preferred embodiment of the present utility model, described spool top has the upper ring portion that an external diameter is less than spool external diameter, and the lower end of described Returnning spring is enclosed within described upper ring portion.
Owing to having adopted technological scheme as above, the beneficial effects of the utility model are: after manual tune puts in place, there is fluctuation once hydrodynamic pressure, spool is movable in spool pressure regulation activity chamber under the effect of Returnning spring, change uninterrupted, reach and control flow and pressure object, and can change by look nut the decrement of Returnning spring, to change the pressure regulation ability of spool.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is a kind of embodiment's of the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Figure 1, a kind of oils regulating valve comprises valve body 100, valve gap 200, valve rod 300, spool 400, valve seat 600, actuator 700, and valve gap 200 is fixed on valve body 100 by fixing bolt assembly 210.
Between valve gap bottom 201, valve body 100 inner chamber tops, spool 400 tops, surround a spool pressure regulation activity chamber 500, in spool pressure regulation activity chamber 500, be provided with look nut 510 and Returnning spring 520.Valve body 100 inner chamber upper inside wall are provided with internal thread 110, the outer wall of look nut 510 is provided with the outside thread 511 coordinating with internal thread 110, the upper end of Returnning spring 520 props up look nut 510, the lower end of Returnning spring 520 is enclosed within the upper ring portion 410 at spool 400 tops, prevents the radial displacement of Returnning spring 520.
In order to reach better voltage regulation result, valve rod 300 in the present embodiment comprises upper valve rod 320 and lower valve rod 310, between upper valve rod 320 and lower valve rod 310, connect by an elastomer block 330, the upper end of upper valve rod 320 is connected with actuator 700, and the lower end of lower valve rod 310 is successively through being connected with spool 400 after valve gap 200, look nut 510 and Returnning spring 520.Valve seat 600 in the lower end surface of spool 400 and valve body 100 seals.
Working principle of the present utility model is as follows:
After putting in place by actuator's manual tune spool, there is fluctuation once hydrodynamic pressure, spool is movable in spool pressure regulation activity chamber under the effect of Returnning spring, changes uninterrupted, reaches and controls flow and pressure object.If find that the pressure regulation ability of spool 400 can not adapt to existing flow pressure, can change by look nut 510 decrement of Returnning spring 520, to change the pressure regulation ability of spool 400.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
