Abstract
The invention aims to provide a gear mechanism reversing valve. The reversing valve comprises a gear, a T-shaped threaded shaft, a sleeve, a valve body, a sliding block and a valve element. The valve body and the sleeve are connected and both are of a hollow structure. The hollow part of the valve body and the hollow part of the sleeve are communicated. The T-shaped threaded shaft is matched with inner T-shaped threads of the sliding block through outer T-shaped threads on the right of the T-shaped threaded shaft. The sliding block and the valve element are connected into a whole. The right of the T-shaped threaded shaft, the sliding block and the valve element are located in the hollow part of the sleeve and the hollow part of the valve body. A bearing box is arranged at one end of the sleeve. A first tapered roller bearing and a second tapered roller bearing are installed in the bearing box. A shaft ring is arranged on the T-shaped threaded shaft. The first tapered roller bearing and the second tapered roller bearing are located on the two sides of the shaft ring respectively. A first spring is arranged between the sliding block and the valve body. A second spring is arranged between the sliding block and the bearing box. The left end of the T-shaped threaded shaft is connected with the gear through an anti-rotating key. A first oil port, a second oil port and a third oil port are formed in the valve body. The gear mechanical reversing valve is simple and reliable in structure, automatic and capable of being used for large flow and high pressure occasions.
Description
Technical field
What the present invention relates to is a kind of valve, specifically selector valve.
Background technique
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 selector valves can't meet the needs of application reliably, also certain limitation of each comfortable application.For example, hand-operated direction valve is only suitable for for intermitten and requires manually operated small flow occasion; Solenoid directional control valve needs extra power supply, has increased extra 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 extra oil circuit control.
Summary of the invention
The object of the present invention is to provide a kind of gear mechanism formula selector 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 selector valve, it 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 sleeve communicates, 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 block and spool link into an integrated entity, the right part of T shape thread spindle, slide block and spool are positioned at the hollow space of sleeve and valve body, the end of sleeve arranges bearing housing, the the first-the second tapered roller bearing is installed in bearing housing, on T shape thread spindle, the axle collar is set, the the first-the second tapered roller bearing lays respectively at the both sides of the axle collar, the first spring is set between slide block and valve body, the second spring is set between slide block and bearing housing, the left part of T shape thread spindle is connected with gear by antirotation keys, first-, tri-hydraulic fluid ports are set on valve body, when spool is positioned at one end of its stroke, the first hydraulic fluid port communicates with the second hydraulic fluid port, when spool is positioned at the other end of its stroke, the second hydraulic fluid port communicates with the 3rd hydraulic fluid port.
The present invention can also comprise:
1, the left part of T shape thread spindle and gear arranges shaft end ring, and gear is carried out axially locating by shaft end ring.
Advantage of the present invention is:
Because adopting mechanical gear is the driving source of valve commutation, so switch valve is reliable, is convenient to automation 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 needs only while exceeding a fixing turn to a direction rotation, spool just moves to one end fixing, and gear is rotated further this kind of state without impact.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Embodiment
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., selector valve part 12～16 etc., 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 axially locating of gear 2 compresses shaft end ring 5 by the first bolt 4 and realizes.
On T shape thread spindle 19, have the axle collar 6, the axle collar 6 left and right sides have 7,8, two tapered roller bearings of the first-the second tapered roller bearing to be installed in bearing housing 1, and its axial restraint and compression act on bearing (ball) cover 23 by 4 the 4th bolts 21 and realize.
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 screw-thread fit 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 is connected by the second bolt 17 with spool 15.
As Fig. 1, clockwise rotate gear 2, due to T shape thread spindle 19 and the screw-thread fit of slide block 9, make slide block 9 together with spool 15 to left movement.Gear 2 continues to turn clockwise, slide block 9 continues to left movement, when the internal thread of slide block 9 and the outside thread of T shape thread spindle 19 depart from while coordinating, be close to T shape thread spindle 19 externally threaded left sides on the right side of effect bottom slide block 9 internal threads of the second spring, now be 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 screw-thread fit of slide block 9, slide block 9 is moved right together with spool 15.Continue to be rotated counterclockwise gear 2, slide block 9 continues to move right, when the internal thread of slide block 9 and the outside thread of T shape thread spindle 19 depart from while coordinating, be close to T shape thread spindle 19 externally threaded right sides in the left side of effect bottom slide block 9 internal threads of the first spring, now continue to rotate counterclockwise gear 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 selector valve that changes valve element position that transfers with gear, when gear exceedes a fixing turn to a direction rotation, spool moves to one end fixing; When gear exceedes a fixing turn to another direction rotation, 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, is moved beyond certain distance to another direction, selector valve commutation.
