Abstract
The utility model discloses a handle rotary-operation multiway valve, which includes a valve body, a valve core arranged in the valve body, a front cover, a rear cover and a handle connected with the valve core, wherein a spiral bushing is arranged among the rear cover, the valve body as well as the valve core; the spiral bushing and the valve core are coaxially and fixedly connected; and a friction positioning device and a spiral guide pole matched with the rear cover and the spiral bushing are further arranged on the rear cover. As the handle rotary-operation multiway valve provided by the utility model has a novel structure, and changes push-and-pull operation of the handle into rotary operation, the operation is simpler and more convenient, and the unique friction positioning device enables the multiway valve to be more reliably positioned.
Description
Technical field
The utility model relates to a kind of hydraulic multitandem valve, particularly a kind of handle rotary manipulation multi-way valve.
Background technique
Existing manual reverse of direction hydraulic multitandem valve adopts the push-pull fashion switching-over, promptly pushes away the multi-way valve operating grip forward, or pulls back the multi-way valve operating grip, realizes the UNICOM of the different oil circuits of multi-way valve.Because spool and valve body valve opening matching gap are little, spool is easy to hair fastener, even can not commutate.Smooth and easy for guaranteeing the spool axial motion, often to suitably add big valve core and valve body valve opening matching gap, it is that the valve internal leakage increases that the problem of bringing is strengthened in the gap; Valve performance descends; And existing multi-way valve steel ball positioning device all be the limiting valve mandrel to straight line motion because the power or the vibration equipment of hydraulic multitandem valve is housed of surging, positioning device is escape easily often; Locate failure causes adverse consequences.
Summary of the invention
The utility model technical problem to be solved is the shortcoming that overcomes above-mentioned manually-operable multi-way valve, provides a kind of handle rotatable operation multi-way valve, and the technological scheme that it adopts is: a kind of handle rotary manipulation multi-way valve; Comprise valve body; Place the spool in the valve body, protecgulum, bonnet; And the handle that is connected with spool; It is characterized in that: also be provided with screw-casing between said bonnet, valve body and the spool, screw-casing is fixedly connected with spool is coaxial, and also is provided with friction positioning device and the spiral guide pillar that is complementary with bonnet and screw-casing on the said bonnet.
The utility model technical characteristics further is:
Described friction positioning device comprises the column that has endoporus that is connected with bonnet, and the locking ball, retaining spring and locknut that is connected with column and the adjusting screw that place the column endoporus.
The rotary orientation of described screw-casing is left-handed or dextrorotation.
The lead of screw of described screw-casing is greater than the twice of poppet shaft to one-sided stroke.
Described spool is connected through connecting rod with handle.
Described screw-casing is provided with axially locating groove, helical guide groove and friction setting circle cambered surface.
Described spiral guide pillar be provided with screw-casing on the plush copper that is complementary of helical guide groove.
Described multi-way valve is integral multi-way valve or split type multi-way valve.
The beneficial effect of the utility model is: because this novel structure of a kind of handle rotary manipulation of the utility model multi-way valve; Become the handle push-and-pull and be operating as rotary manipulation; Therefore operation is easier, and owing to adopt unique friction positioning device, therefore makes the location of multi-way valve more reliable.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
Referring to figs. 1 through shown in Figure 5, a kind of handle rotary manipulation multi-way valve comprises valve body 1; Place the spool 2 in the valve body 1, protecgulum 3, bonnet 4; And the handle 5 that is connected with spool 2; Also be provided with screw-casing 6 between wherein said bonnet 4, valve body 1 and the spool 2, screw-casing 6 and spool 2 coaxial fixed connections, and also be provided with the friction positioning device 7 and spiral guide pillar 8 that is complementary with bonnet 4 and screw-casing 6 on the said bonnet 4.
Described friction positioning device 7 comprises the column that has endoporus 701 that is connected with bonnet 4, and the locking ball 702, retaining spring 703 and locknut 704 that is connected with column 701 and the adjusting screw 705 that place column 701 endoporus.
The rotary orientation of described screw-casing 6 is left-handed or dextrorotation.
The lead of screw of described screw-casing 6 is greater than the twice of spool 2 axial one-sided strokes.
Described screw-casing 6 is provided with axially locating groove 601, helical guide groove 602 and friction setting circle cambered surface 603.
Described spiral guide pillar 8 be provided with screw-casing 6 on the plush copper that is complementary of helical guide groove 602.And the center line of spiral guide pillar 8 and the center line of friction positioning device are point-blank.
Described multi-way valve is integral multi-way valve or split type multi-way valve.
When active gage is two or during more the couplet more, interfere for avoiding a plurality of handle 5 left-right rotation, can be connected through connecting rod between described spool 2 and the handle 5, come the distance between regulating spool 2 and the handle 5 through the number of regulating connecting rod.
The working principle of the utility model is following: rotatable handle 5 left; Spool 2 is followed together with screw-casing 6 and is rotated, and helical guide groove 602 receives the leading role of spiral guide pillar 8, according to the power screw principle; Spool 2 moves right (annotate: this instance spiral chute rotation direction is dextrorotation); Locking ball 702 is jumped out from axially locating groove 601, and locking ball 702 rolls on friction setting circle cambered surface 603, is pressed in all the time on the friction setting circle cambered surface 603 through retaining spring 703; Form frictional force, the frictional force size is set through adjusting screw 705.During spool 2 lean-withs, screw-casing 6 moves right ultimate range L2 (being spool 2 maximum effective travels) to bonnet 4 end face distance L1 and spool and equates.If do not need full flow in actual the use, can handle be stopped in 0-90 degree angular range, because the friction positioning action, spool 2 just is parked in special position, at this moment spool 2 is partly opened with the restriction that valve body 1 forms, and plays the effect of throttle grverning.Rotatable handle left: spool moves right, and the P mouth communicates with the A mouth, and the B mouth communicates with the T mouth; Rotatable handle to the right: spool is to left movement, and the P mouth communicates with the B mouth, and the A mouth communicates with the T mouth.
Because this novel structure of a kind of handle rotary manipulation of the utility model multi-way valve becomes the handle push-and-pull and is operating as rotary manipulation, therefore operation is easier, and owing to adopt unique friction positioning device, therefore makes the location of multi-way valve more reliable.
