Description
Technical field
What the present invention relates to is a kind of valve, specifically reversal valve.
Background technology
The mode difference that spool-type valves moves according to promotion change-over valve core can be divided into: hand-operated direction valve,Solenoid directional control valve, hydraulicchange-over valve etc. But in special occasion, these reversal valves can't be reliableMeet the needs of application, also certain limitation of each comfortable application scenario. For example, hand-operated direction valve is only suitable for usingIn intermitten and require manually operated low discharge occasion; Solenoid directional control valve needs extra power supply, has increasedExtra circuit, again because the suction of electromagnet is limited, so it is not suitable for the occasion that flow is too large;Hydraulicchange-over valve is used in the occasion that pressure is high, flow large, spool is taken action stroke length, but needs extraOil circuit control.
Summary of the invention
The object of the present invention is to provide a kind of gear mechanism formula reversal valve that can be used for big-flow high-pressure occasion.
The object of the present invention is achieved like this:
A kind of gear mechanism formula of the present invention reversal valve, is characterized in that: comprise gear, T shape thread spindle, sleeve,Valve body, slide block, spool, valve body is connected with sleeve and is hollow structure, the hollow space of valve body and sleeveCommunicate, T shape thread spindle matches by the outer T shape screw thread of its right part and the interior T shape screw thread of slide block, slide blockLink into an integrated entity with spool, right part, slide block and the spool of T shape thread spindle are positioned at the hollow of sleeve and valve bodyPart, the end of sleeve arranges bearing housing, and the first-the second taper roll bearing is installed in bearing housing, T shape spiral shellOn line axle, the axle collar is set, the first-the second taper roll bearing lays respectively at the both sides of the axle collar, slide block and valve body itBetween the first spring is set, the second spring is set between slide block and bearing housing, the left part of T shape thread spindle is passed throughAntirotation keys is connected with gear, and first-, tri-hydraulic fluid ports are set on valve body, when spool is positioned at one end of its stroke, theOne hydraulic fluid port communicates with the second hydraulic fluid port, when spool is positioned at the other end of its stroke, and the second hydraulic fluid port and the 3rd hydraulic fluid port phaseLogical.
The present invention can also comprise:
1, the left part of T shape thread spindle and gear arranges shaft end ring, and it is axially fixed that shaft end ring carries out gearPosition.
Advantage of the present invention is:
Because adopting mechanical gear is the drive source of valve commutation, so switch valve is reliable, be convenient to automaticallyChange and control, and can be used for the occasion of big-flow high-pressure.
Because the setting of T-shaped thread spindle, slide block, the first spring and the second spring, so gear is as long as to oneIndividual direction is rotated while exceeding a fixing turn, and spool just moves to one end fixing, and gear is rotated further this kindState is without impact.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
For example the present invention is described in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1, the present invention mainly comprises commutation power section 2～8,19 etc., reversal valve part 12～16Deng, framework standing part 1,11 etc.
T shape thread spindle 19 left end spindle nose places are connected with gear 2 by antirotation keys 3. The axial location of gear 2Compressing shaft end ring 5 by the first bolt 4 realizes.
On T shape thread spindle 19, have the axle collar 6, the axle collar 6 left and right sides have the first-the second taper roll bearing 7,8, two taper roll bearings have been installed in bearing housing 1, and its axial restraint and compression are by 4 the 4thBolt 21 acts on that bearing (ball) cover 23 realizes.
Bearing housing 1 and sleeve 11 link together by 4 the 5th bolts 22.
The right-hand part of T shape thread spindle 19 has outer T shape screw thread, the interior T shape threaded engagement of itself and slide block 9.The right flank of slide block 9 contacts with the first spring 10, and left side contacts with the second spring 20. Slide block 9 and spool15 connect by the second bolt 17.
Valve body 16 is connected by 4 the 3rd bolts 18 with sleeve 11, on valve body, have the first hydraulic fluid port 12,The second hydraulic fluid port 13, the 3rd hydraulic fluid port 14.
As Fig. 1, clockwise rotate gear 2, due to T shape thread spindle 19 and the threaded engagement of slide block 9, makeSlide block 9 together with spool 15 to left movement. The gear 2 that continues to turn clockwise, slide block 9 continues to left movement,When the internal thread of slide block 9 and the external screw thread of T shape thread spindle 19 depart from while coordinating, under the effect of the second springThe right side of slide block 9 internal threads is close to T shape thread spindle 19 externally threaded left sides, is now rotated further gear 2,Slide block 9 is communicated with the invariant position of spool 15, and this state first hydraulic fluid port 12 and the second hydraulic fluid port 13 communicate.
In like manner, rotate counterclockwise gear 2, due to T shape thread spindle 19 and the threaded engagement of slide block 9, make slidingPiece 9 moves right together with spool 15. Continue to be rotated counterclockwise gear 2, slide block 9 continues to move right, whenWhen the internal thread of slide block 9 coordinates with the external screw thread disengaging of T shape thread spindle 19, glide in the effect of the first springThe left side of piece 9 internal threads is close to T shape thread spindle 19 externally threaded right sides, now continues to rotate counterclockwise toothWheel 2, slide block 9 is communicated with the invariant position of spool 15, and this state second hydraulic fluid port 13 and the 3rd hydraulic fluid port 14 communicate.
The invention discloses a kind of positive and negative reversal valve that changes spool position that transfers with gear, gear is to oneDirection is rotated while exceeding a fixing turn, and spool moves to one end fixing; Gear rotates super to another directionWhile crossing a fixing turn, spool moves to the other end fixing. If the gear in this valve coordinates tooth bar to use,Can realize tooth bar and be moved beyond certain distance to a direction time, spool moves to one end fixing, to separatelyA direction is moved beyond certain distance, reversal valve commutation.
