Abstract
The utility model discloses a dual one-way throttle valve, relates to the field of flow control, and solves the problems that the structure is complicated and the installation volume is large in the prior art. The throttle valve is coaxially provided with symmetrical valve cavities at the two ends of a valve body; the valve cavities are not communicated with each other; the two valve cavities are internally provided with one-way throttle valves of the same structure; the valve body is further provided with an oil inlet and an oil outlet which are communicated with the two valve cavities respectively; a throttle port of the throttle valve is formed at the junction of the oil inlet, the oil outlet and the valve cavities; each one-way throttle valve consists of a valve element, a spring fixed at the rear end of the valve element and a throttle threaded rod sleeved on the spring; the throttle area of the throttle port can be adjusted by rotating the throttle threaded rods. Compared with the existing one-way throttle valve, the dual one-way throttle valve has the advantages of small occupied space and convenient installation and maintenance, the conversion between inlet throttle and outlet throttle can also be realized by rotating the valve body by 180 degrees along the axial direction.
Description
Technical field
The utility model relates to flow control field, is specifically related to a kind of simple in structurely, and assembling volume is little, can realize the Double throttle check valve of inlet throttle and outlet throttling exchange.
Background technique
Throttle valve is a kind of flow control valve, it is while utilizing oil stream by throttle valve, to change the pressure that passage section carrys out adjust flux or changes valve front and back, for one-way throttle valve, in the time of fluid forward flow, play throttling action, in the time of reverse fluid flow, fluid promotes spool, makes spool and valve body form major path, do not play throttling action, become one-way valve.At present to exist assembling volume large for the structural type of conventional one-way valve, occupies space large, and only play throttling action when convection cell forward flow, do not play throttling action when reverse flow, cannot realize bidirectional throttle.
Model utility content
The defect existing in order to solve above-mentioned technology, it is a kind of simple in structure that the utility model provides, and assembling volume is little, can realize the Double throttle check valve that inlet throttle and outlet throttling exchange.
The utility model is realized the technological scheme that above-mentioned technique effect adopts:
A kind of Double throttle check valve, comprise valve body, wherein, described valve body two ends are coaxially provided with symmetrical mutual disconnected valve pocket, in described valve pocket, be provided with the one-way throttle valve that structure is identical, on described valve body, be also provided with respectively and filler opening and the oil outlet of described valve pocket conducting, the intersection of described filler opening, described oil outlet and described valve pocket forms the restriction of throttle valve.
Above-mentioned a kind of Double throttle check valve, described one-way throttle valve by spool, be fixed on the spring of described spool rear end and the throttling screw that is socketed on described spring forms.
Above-mentioned a kind of Double throttle check valve, the front end of described spool is positioned at described restriction place, for regulating the orifice size of described restriction.
Above-mentioned a kind of Double throttle check valve, described oil outlet is provided with the side opening with described valve pocket conducting.
The beneficial effects of the utility model are: this throttle valve adopts overlapping structure composition Double throttle check valve, and the space of occupying is little, and installation and maintenance are convenient, can conveniently realize inlet throttle and outlet throttling and exchange.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-valve body, 2-valve pocket, 3-spool, 4-throttling screw, 5-spring, 6-side opening, 7-restriction.
Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
Shown in Fig. 1, a kind of Double throttle check valve, described throttle valve is coaxially provided with symmetrical mutual disconnected valve pocket 2 at valve body 1 two ends, in described valve pocket 2, be provided with the one-way throttle valve that structure is identical, on described valve body, be also provided with respectively and filler opening and the oil outlet of two valve pocket 2 conductings, the intersection of described filler opening, oil outlet and valve pocket 2 forms the restriction 7 of throttle valve.This one-way throttle valve by spool 3, be fixed on the spring 5 of spool 3 rear ends and the throttling screw 4 that is socketed on spring 5 forms.The front end of spool 3 is positioned at restriction 7 places, for the orifice size of adjusting joint head piece 7.For the ease of by reference to the accompanying drawings embodiment of the present utility model being described, the filler opening of left side valve pocket 2 is labeled as B, and oil outlet is labeled as B1, the filler opening of right side valve pocket 2 is labeled as A, oil outlet is labeled as A1, when enforcement, is provided with the side opening 6 with valve pocket 2 conductings on oil outlet (B1, A1).
The working principle of this throttle valve is: in the time that fluid enters from filler opening B, due to spool 3 under the effect of spring 5 in initial position, the front end of spool 3 forms certain obstruct to restriction 7, causes the orifice size of restriction 7 less, and fluid plays certain throttling action through out-of-date.Enter after oil outlet B1 by narrow and small restriction 7 at fluid, the side opening 6 of fluid from oil outlet B1 enters in valve pocket 2, the fluid that flows into valve pocket 2 applies hydraulic thrust to the front end of spool 3, the active force that makes spool 3 overcome spring 5 moves right, so, restriction 7 is opened, cavity from filler opening B to oil outlet B1 forms straight-through cavity, in this process, left-handed throttling screw 4, can make spool 3 move right, the orifice size of restriction 7 increases, corresponding flow increases, dextrorotation throttling screw 4, can make spool 3 be moved to the left, the orifice size of restriction 7 reduces, corresponding flow reduces, play the effect of inlet throttle.In the time that fluid flows into from oil outlet B1, the side opening 6 of fluid from oil outlet B1 enters in valve pocket 2, the fluid that flows into valve pocket 2 promotes spool 3 and moves right, the orifice size of restriction 7 increases, between oil outlet B1 and filler opening B, form straight-through cavity, fluid is from oil outlet B1 to filler opening B one-way flow.The one-way throttle valve working principle on right side is identical with the one-way throttle valve working principle in left side.
More than show and described basic principle of the present utility model, 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; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not depart from the utility model spirit and scope, the utility model also has various changes and modifications; these changes and improvements all fall in claimed scope of the present utility model, and the protection domain that the utility model requires is defined by appending claims and equivalent thereof.
