Abstract

The utility model discloses a reversing valve, including valve body and the core of setting in the valve body, its characterized in that, the valve body still include with the last passageway of external pipe connection and passageway down, upper and lower passageway both ends are connected with the core respectively, the core changes epaxial and goes up one including setting up in, three case down, goes up that two cases feed through together with last passageway in, in, two lower cases feed through together with lower passageway. Among this technical scheme, reversing valve's case through a pivot will go up in, down three case set up together, when rotating the pivot, in going up down three case all controlled. Adopt this technical scheme, it is very long that the valve body can be done, and the asynchronous potential safety hazard that causes of control between the case has been avoided simultaneously to front and back pipeline multiplex control's needs when satisfying the pipeline laying.

Description

A kind of reversal valve

Technical field

The utility model relates to pipe-line equipment technical field, especially relates to a kind of reversal valve.

Background technology

Field is laid at present at fluid line, pipeline often needs a multiple loop of pipeline communication when Comprehensive Control, and need between the loop of control distant sometimes, common multiple-way valve is adopted to reach needs, then add control difficulty with multiple valve, what can not ensure to control between valve is synchronous simultaneously.

Utility model content

In order to make up the defect of above-mentioned pipeline valve, the utility model proposes a kind of reversal valve.

Its technical scheme is, a kind of reversal valve, comprise valve body and be arranged on the core body in valve body, it is characterized in that, described valve body also comprises the upper channel and lower channel that are connected with extraneous pipeline, and upper and lower passage two ends are connected with core body respectively, and described core body comprises three, the upper, middle and lower spool be arranged in a rotating shaft, upper, in together with two spools are communicated to upper channel, in, together with lower two spools are communicated to lower channel.In the technical program, three, upper, middle and lower spool is set to together by a rotating shaft by the spool of reversal valve, and when rotating shaft, upper, middle and lower three spools are all controlled.Adopt the technical program, it is very long that valve body can do, and before and after when meeting pipe laying, the needs of pipeline multiple control, avoid between spool simultaneously and control the asynchronous potential safety hazard caused.

Upper and lower spool also with extraneous channel connection.In the technical program, upper bottom spool and extraneous channel connection, can select when in use to take a breath or inner loop with the external world, improve range of application of the present utility model.

Also electric machine assembly is connected with at rotating shaft top.In the technical program, adopt Electric Machine Control valve, valve can be electronic or manual or operated from a distance or fixed cycle operator etc., improves its range of application, has liberated manpower.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of embodiment of utility model;

Fig. 2 is the structural representation of another kind of embodiment of the present utility model;

In figure, 1, valve body; 11, upper channel; 12, lower channel; 2, core body; 21, rotating shaft; 22, upper valve core; 23, middle spool; 24, bottom spool; 3, electric machine assembly.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described further.

Composition graphs 1, a kind of embodiment of the present utility model.A kind of reversal valve, the core body 2 comprising valve body 1 and be arranged in valve body, it is characterized in that, described valve body also comprises the upper channel 11 and lower channel 12 that are connected with extraneous pipeline, upper and lower passage two ends are connected with core body respectively, described core body comprises upper valve core 22, middle spool 23, bottom spool 24, upper, in together with two spools 21 are communicated to upper channel, in, together with lower two spools are communicated to lower channel.In the present embodiment, upper and lower spool also with extraneous channel connection.Also electric machine assembly is connected with at rotating shaft top.

As Fig. 2, in the present embodiment, the circulation passage in valve body has two kinds.

The first, rotary core, makes upper and lower spool open, middle spool is closed, and valve body internal channel is turned into after upper valve core place fluid enters upper channel and flows out along upper channel, and bottom spool place fluid flows out along lower channel after entering lower channel, upper and lower passage fluid is non-interference, flows alone.

The second, rotary spool, upper and lower spool is closed, and middle spool is opened.Then fluid spool from upper channel warp enters lower channel, or in lower channel fluid warp, spool enters upper channel.

In sum, not whole intension of the present utility model: after this, all to have within do by utility model subject spirit any amendment, replacement until improve the projects such as upgrading, include within protection domain of the present utility model.

Claims
