Abstract
The utility model discloses the hydraulic vibration rotates switching -over valve that provides of application has adopted the coaxial bivalve core structure of twin -rotor housing oil pocket and every cylinder body oil pocket case, and on the cylinder body of case and cylinder body movive seal cooperation position and all be equipped with one on the cylinder body between case and the cylinder body end cover and meet the glib talker, a plurality of oil passing groove have evenly been offered to the axial on the case periphery, and two case oil passing groove arrange 12 per minute degree central angles of mistake mutually. This technical scheme has eliminated the epaxial axial force of case load, has guaranteed its reversing operation's high stability and high reliability, has the technological advantage that excitation output efficiency is high.
Description
Technical field
This utility model patent application refers to hydraulicdirectional control valve, in particular drives hydraulic vibration exciter quickly to commutate, meets the hydraulic rotation reversal valve that excited frequency output requires.
Background technology
One technical way of hydraulic pressure excited vibration is that piston valve control is servo-actuated, and it controls reversal valve and mainly includes rotation reversal valve and portable reversal valve.Owing to the commutating speed of hydraulic rotation reversal valve is higher than movable type reversal valve, having the technical advantage that output frequency of vibration is high, structure is also easy to realization, therefore the hydraulic vibration exciter of assembling rotation reversal valve has wider application scope.At present, the typical construction of hydraulic rotation reversal valve is as shown in Figure 1, it constructs for single spool, valve core rotation arranges in valve pocket, seal with inboard wall of cylinder block the valve element circle perimeter surface that coordinates and on it oil guide groove alternately close, open cylinder body oil-in, described oil guide groove is divided into two groups, two groups of oil guide groove are staggered, often group outer end each extend over the oil pocket leading to spool side, the inner all extends to be positioned at the oil-in of spool face axially central authorities, with valve core rotation, piston oil pocket alternately connects with high pressure, low pressure oil way, drives hydraulic cylinder piston to produce displacement vibration, exciting work.From the foregoing, it will be observed that spool both sides subject the hydraulic pressure that height is different, therefore having added thrust bearing in poppet shaft one end, undertaken axial force, produce therewith technical problem is that axle drives increase, and axle drives burden to strengthen, and exciting drives to consume energy and improves；Single spool structure of reversing valve exist another technical problem is that: spool, by the high pressure of both sides oil pocket, low pressure effect, is easily caused between valve element circle perimeter surface and inboard wall of cylinder block generation sealing leak.
Summary of the invention
The goal of the invention of this utility model patent application is while satisfied commutation exciting drives, there is provided a kind of and eliminate axial compressive force difference and the axial force that produces therewith, have that driving power consumption is low, sealing property is excellent, the hydraulic exciting of reliable performance exciting performance rotates reversal valve.The hydraulic exciting that this utility model application provides rotates commutation valve technology scheme, its main technical content is: a kind of hydraulic exciting rotates reversal valve, poppet shaft is through the sealing axis hole of the center flange type dividing plate connecting left and right cylinder body, by left and right cylinder end caps rotating bearing seal rotational support in cylinder body central authorities, two spools in poppet shaft lay respectively in the cylinder body oil pocket of left and right, the most logical some oil groove is uniformly offered on two valve element circle side faces, two spools lead to oil groove be staggered 1/2 often indexing central angle arrange, it is the cooperation phase section simultaneously coordinated with cylinder body oil pocket inwall movable sealing that every the 1/2 of two spools often indexes the periphery that the two of central angle leads between oil groove, each spool coordinates with the movable sealing of its cylinder body on position and is equipped with one on cylinder body between the spool of each cylinder body oil pocket and its cylinder end caps and connects oil nozzle.
The hydraulic exciting of this utility model patent application publication rotates in commutation valve technology scheme, use twin-rotor housing oil pocket and the double spool structure of every cylinder body oil pocket one spool, the both sides making each spool are offset because oil pocket hydraulic pressure is identical, eliminate the axial force load in poppet shaft, eliminate thrust bearing to arrange, simplify structure, improve sealing property, ensure that high stability and the high reliability of its switch operation, there is axle and drive that aerodynamic power is low, its technological merit that exciting energy consumption greatly reduces, exciting delivery efficiency is high.

Detailed description of the invention
Hydraulic exciting disclosed in this utility model application rotates reversal valve, center flange type dividing plate 8 is fixedly connected with flange-interface mode coaxial line with left and right cylinder body 5,15, and left and right cylinder body 5,15 outer end is closed by cylinder end caps 3,13 and O-ring seal 4,14 and constituted left and right cylinder body oil pocket.Poppet shaft 11 is through the sealing axis hole of center flange type dividing plate 8, and by the rotating bearing seal rotational support of left and right cylinder end caps 3,13 on cylinder body axis, in poppet shaft 11, key is fixed with two spools 16,9, and two spools lay respectively in left and right cylinder body oil pocket.The periphery of spool 16,9 coordinates with cylinder body oil pocket inwall movable sealing, the cylinder body at the movable sealing cooperation of cylinder body and between the spool 16,9 of each cylinder body oil pocket and its cylinder end caps 3,13 is equipped with one and connects oil nozzle 1,2,17,12；Uniformly offer the axially logical oil groove 18 that quantity is identical on the periphery of two spools 16,9, the logical oil groove 18 of two spools 16,9 be staggered 1/2 often indexing central angle arrange.Often indexing central angle is the central angle on a spool between two adjacent logical oil grooves.Every the 1/2 of two spools 16,9 often indexes between the logical oil groove of central angle, as shown in Figure 3 and Figure 5, two spools 16,9 after being co-axially mounted, on two spools, one of which 1/2 often indexes the logical periphery between oil groove 18a, 18b of central angle is to coordinate with cylinder body oil pocket inwall movable sealing simultaneously, closes the cooperation phase section connecing oil nozzle 1,2, so ensure high and low hydraulic oil can not while warp lead to oil groove, oil nozzle and piston hydraulic pressure oil supply cylinder.Piston hydraulic cylinder drives the rotation of two spools 16,9 with poppet shaft 11, and alternately the hydraulic circuit through left and right cylinder body oil pocket connects with hydraulic oil, low pressure oil, thus drives hydraulic cylinder piston displacement vibration, exciting to work.
