Description
Technical field
The present invention relates to hydraulic pressure components and parts technical field, concrete relate to a kind of stacked unidirectional throttle valve.
Background technique
Throttle valve is a kind of skeleton symbol flow control valve, and it mainly is to change the pressure that passage section is regulated flow or changed the valve front and back when utilizing oil to flow through throttle valve.For one-way throttle valve, when oil stream forward flow, play throttling action, when oil flows when reverse, oil pressure promotes spool, makes spool and valve body formation major path, does not play throttling action, becomes one-way valve.The CN2660262Y of Chinese patent notice of authorization, the overlapping Double throttle check valve is made up of the identical one-way throttle valve of structure of respectively adorning of symmetry in the cavity of valve body center line both sides, but this kind valve arrangement complexity, lengthwise dimension is bigger than normal, valve body main aperture complex structure, processing cost height.
Summary of the invention
Technical problem to be solved by this invention is, overcomes problems of the prior art, and a kind of stacked unidirectional throttle valve is provided.
In order to address the above problem technological scheme of the present invention is such:
A kind of stacked unidirectional throttle valve, comprise that two ends have the valve body of symmetrical main aperture, has the balance runner that communicates with main aperture on the described valve body, be provided with the one-way valve of symmetry in the described symmetrical main aperture, be provided with the adjustment sleeve of the symmetry that is connected with valve seal in the outside of one-way valve, it is characterized in that, has step hole in the described adjustment sleeve, the step hole outboard end is provided with the adjusting screw of inserting step hole, another side of step hole is provided with throttling valve core, be with spring on the throttling valve core, have a unthreaded hole that matches with throttling valve core in the described one-way valve.
Described step hole outboard end has internal thread, has outside thread on the described adjusting screw, and described adjusting screw and adjustment sleeve also are provided with an adjusting nut by being threaded on the adjusting screw, and the adjusting nut outside has the packing ring of limitting to the adjusting screw position.
Described throttling valve core front end has the triangle throttling groove, and the unthreaded hole length in the described one-way valve is greater than the length of triangle throttling groove.
Be with seal ring on the throttling valve core in the described step hole.
Described adjustment sleeve is threaded with valve body, is provided with seal ring between adjustment sleeve and the valve body.Beneficial effect, compact structure of the present invention, boundary dimension is less relatively, and fitting operation is very convenient, and is with low cost, and market prospects are wide.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Referring to Fig. 1, a valve body 1, a main aperture is respectively made at two ends along its length, and actuator port A1 and B1 are arranged above, and actuator port A2 and B2 are arranged below, and actuator port communicates with main aperture by the cast runner.
Dress one-way valve 2, spring 3, seal ring 4, adjustment sleeve 7 in valve body 1 main aperture.
Several grades of step holes are made in adjustment sleeve 7 inside, dress throttling valve core 6, seal ring 5.The other end is a tapped hole, debugs joint screw 10.Dress locking nut 8 and packing ring 9 on the adjusting screw 10.
Throttling valve core 6 ends have the triangle throttling groove.
One-way valve 2 center is vertically made an accurate unthreaded hole, matches with throttling valve core 6, and matching gap is restricted, too greatly then internal leakage is big, too little then easily stuck, when throttling valve core 6 push over low be throttling hour, should have one section cylinder of the triangle throttling groove that exceeds throttling valve core 6 to cooperate and hide length.
The stroke of adjustment sleeve 7 inner outermost level step hole restriction one-way valves 2 guarantees that spring 3 is not influenced working life by excessive compression; The step hole of intermediate step hole and one-way valve 2 is as the outside fix hole of spring 3, and the precompression length of definite spring 3, guarantees that one-way valve has definite cracking pressure; The one-level step hole cooperates with throttling valve core 6, and the outside stroke of restriction throttling valve core 6, and throttling valve core 6 is not deviate from when the throttling opening is maximum, in addition, contacts with seal ring in the groove on the throttling valve core 6, seals.
The locking nut 8 of adjusting screw 10 outsides when adjusting screw 10 is regulated the throttling openings to the needs position, rotates to adjustment sleeve 7 to the direction of adjustment sleeve 7 and to be adjacent to, and makes adjusting screw 10 unlikely loosening, guarantees that the throttling openings of sizes stablizes constant.
Sealing girth sheets 11 be contained in valve body below, the through hole corresponding with valve body hole arranged above, at runner hole place dress seal ring 12.
Working procedure is as follows:
If hydraulic oil flows into from the A2 mouth, flow to the A1 mouth by restriction on the throttling valve core 6 and the radial hole on the one-way valve, at this moment, one-way valve 2 is subjected to the impacting force of spring 3 and the effect of fluid pressure, is pressed on the valve body, and fluid can only pass through from restriction.
If hydraulic oil flows into from the A1 mouth, then hydraulic coupling promotes the power that one-way valve 2 overcomes spring 3 and moves, and fluid freely passes through from the space between one-way valve 2 and the valve body 1, arrival A2.
Valve is rotated 180 degree along the X-X axle, can realize the conversion of hydraulic system meter in and meter out.
Compact structure of the present invention, boundary dimension are less relatively, and fitting operation is very convenient, and be with low cost, and market prospects are wide.
More than show and described basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
