Abstract
The utility model discloses a three-way hydraulic reversing valve which comprises a valve body, a valve element, an air cylinder and a sealing rod. The valve body comprises an upper valve hole, a lower valve hole, a left valve hole and a right valve hole, wherein the four valve holes are mutually communicated. One end of the valve element penetrates through the lower valve hole and is in sealing with the upper valve hole in a matched mode, and the other end of the valve element is connected with the air cylinder in a control mode. The top of the valve element comprises two through holes which are led to the left side and the right side of the valve element, and the through holes are communicated with the left valve hole and the right valve hole in a matched mode. The bottom of the valve element comprises longitudinal holes communicated with the through holes, and sealing rods penetrate through the longitudinal holes and are in sealing with the through holes in a matched mode. The three-way hydraulic reversing valve is high in functionality and low in cost.
Description
Technical field
The utility model belongs to hydraulic flow commutating device field, is specifically related to a kind of three-way hydraulic selector valve.
Background technique
The structure of traditional hydrovalve generally has 2 kinds, and a kind of is that the liquid of sprue is flowed to respectively to two runners, and another kind is that the liquid of sprue can only lead to an independent runner by changement; So the hydrovalve of two kinds of different structures need to be set while using, therefore increased cost.
Model utility content
(1) technical problem that will solve
The technical problems to be solved in the utility model is to propose a kind of functional strong three-way hydraulic selector valve, has solved the high problem of cost in conventional art.
(2) technological scheme
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of three-way hydraulic selector valve, comprises valve body, spool, cylinder and seal bar; Described valve body includes four valve openings that are interconnected up and down, one end of described spool through after the valve opening of downside with the valve opening fitted seal of upside, the other end and cylinder control connection; The top of described spool includes 2 through holes that lead to respectively spool left and right side, and described through hole coordinates and is communicated with the valve opening of the left and right sides; The bottom of described spool includes the longitudinal hole being communicated with through hole, described seal bar through after longitudinal hole with through hole fitted seal.
The top of described spool is provided with the first screw and the first sealing gasket, and described the first screw is connected in fixing with spool after the first sealing gasket.
The valve opening of described spool and upside is by the first sealing gasket fitted seal.
The top of described seal bar is provided with the second sealing gasket and the second screw; Described the second sealing gasket and seal bar are tightly connected by the second screw, between described through hole and seal bar, by the second sealing gasket, are tightly connected.
Described the first sealing gasket includes 2 coaxial with through hole and be communicated with water holes.
(3) beneficial effect
Three-way hydraulic selector valve of the present utility model, by 2 through holes that are communicated with left and right valve opening are set on traditional spool, and seal bar fitted seal is set, therefore not only can control simultaneously, the connected sum of two valve openings in left and right is stopped up, the connected sum that can control again an independent valve opening stops up, thereby functional strong, provide cost savings.
Accompanying drawing explanation
Fig. 1 is the first view of three-way hydraulic selector valve of the present utility model;
Fig. 2 is the second view of three-way hydraulic selector valve of the present utility model;
Fig. 3 is the sectional view of A-A in Fig. 1;
In figure, 1 is that valve body, 2 is that spool, 3 is that cylinder, 4 is that seal bar, 5 is that valve opening, 6 is that through hole, 7 is that longitudinal hole, 8 is that the first screw, 9 is that the first sealing gasket, 10 is that the second sealing gasket, 11 is that the second screw, 12 is water hole.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
A kind of three-way hydraulic selector valve as shown in figures 1 and 3, comprises valve body 1, spool 2, cylinder 3 and seal bar 4; Described valve body 1 includes four valve openings 5 that are interconnected up and down, one end of described spool 2 through the valve opening 5 of downside after and valve opening 5 fitted seal of upside, this structure can make the valve opening 5 (sprue) of upside circulate or stop up with the valve opening 5 (runner) of the left and right sides simultaneously, the other end and cylinder 3 control connections, very convenient by cylinder control operation; The top of described spool 2 includes 2 through holes 6 that lead to respectively spool 2 left and right sides, and described through hole 6 coordinates and is communicated with the valve opening 5 of the left and right sides; The bottom of described spool 2 includes the longitudinal hole 7 being communicated with through hole 6, and described seal bar 4 is rear and through hole 2 fitted seal through longitudinal hole 7.This structure can make the valve opening 5 (sprue) of upside and an independent valve opening 5 (runner) circulation of the left and right sides or stop up.Therefore selector valve of the present utility model is functional strong, provides cost savings.
The top of described spool 2 is provided with the first screw 8 and the first sealing gasket 9, and described the first screw 8 is connected in fixing with spool 2 through the first sealing gasket 9 is rear.The valve opening 5 of described spool 2 and upside is by the first sealing gasket 9 fitted seal.By the first sealing gasket 9, can strengthen the sealing effect between spool 2 and valve opening 5.
The top of described seal bar 4 is provided with the second sealing gasket 10 and the second screw 11; Described the second sealing gasket 10 is tightly connected by the second screw 11 with seal bar 4, between described through hole 6 and seal bar 4, by the second sealing gasket 10, is tightly connected.By the second sealing gasket 10, can strengthen the sealing effect between seal bar 4 and through hole 6.
Described the first sealing gasket 9 includes 2 coaxial with through hole 6 and be communicated with water holes 12, by this water hole 12, liquid is flowed in through hole 6 from the valve opening 5 of upside.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
