Abstract
The invention relates to a valve, in particular to a three-position four-way gate valve, and discloses a changeover non-return controller. The changeover non-return controller comprises a valve shell (1) and a valve element (2). The valve element (2) is provided with a pull rod (3) stretching out of the valve shell. The valve shell (1) is provided with a plurality of liquid inlet and liquid outlet sets which penetrate the front wall and the rear wall and are used for being connected with a pipeline. Each liquid inlet and liquid outlet set comprises a liquid inlet (4) and a liquid outlet (5). The valve element (2) is in a plate shape and is provided with a plurality of overflowing holes (6), so that when the valve element (2) is at different work positions, one or more overflowing holes (6) in the valve element (2) correspond to one or more liquid inlet and liquid outlet sets in the valve shell (1) in position. The changeover non-return controller has the beneficial effects of being reasonable in structure, small in size, small in occupied space and capable of achieving instant turnoff, the control needs for some special pipelines can be met, the directions of flowing media in changeover pipelines can be automatically controlled, and the function that cutoff can be completed instantly at high pressure is achieved.
Description
Technical field
The present invention relates to valve, be specifically related to a kind of 3-position 4-way formula slide valve。
Background technology
Existing pipeline switches circulation medium direction manually switch different valve and realize, during circulation medium in the reverse stop valve under high pressure instantaneous trip non-return pipeline cut off, exist and fit badly and the problem of fragile valve, the generation of reflux phenomenon often occurs。Existing cross valve volume is big, takes up space big, and owing to valve core structure limits so that it is inflow-rate of water turbine is restricted, it is impossible to meet the structural requirement of special pipe line structure circulation device, and the functional requirement being difficulty with under high pressure instantaneous trip。
Summary of the invention
The technical problem to be solved is: provide a kind of rational in infrastructure, volume is little, occupy little space and can moment turn off switching non-return controller, to meet some special pipelines control needs, circulation medium direction in switching pipeline can be automatically controlled and complete the function of cut-out with having energy moment under high pressure。
The technical solution of the present invention is: switching non-return controller, including valve casing and the spool being sealed in valve casing, spool is provided with the pull bar stretching out valve casing, spool different operating position in valve casing can be controlled by pull bar to slide, described valve casing is provided with the liquid in-out mouth for connecting line of some groups of through front and rear walls, often group liquid in-out mouth includes an inlet and a liquid outlet, described spool is tabular, which is provided with some flowing holes, make spool when different operating position, one or more flowing hole on spool is corresponding with a group on valve casing or many group liquid in-out mouth positions, these liquid in-out mouths are made to be in opening state, and when spool not having flowing hole corresponding with the liquid in-out mouth position on valve casing, then controller is off state。
The solution have the advantages that: it have rational in infrastructure, volume is little, occupy little space and can moment turn off switching non-return controller advantage, some special pipelines can be met and control needs, circulation medium direction in switching pipeline can be automatically controlled and complete the function of cut-out with having energy moment under high pressure。When thickness varies less or is constant, it is possible to the aperture of valve opening is arbitrarily set, inflow-rate of water turbine is made to be arranged as required to。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the A-A sectional view of Fig. 1。
Detailed description of the invention
As illustrated in fig. 1 and 2, switching non-return controller, including valve casing 1 and the spool 2 being sealed in valve casing 1, spool 2 is provided with the pull bar 3 stretching out valve casing, the spool 2 different operating position in valve casing 1 can be controlled by pull bar 3 to slide, described valve casing 1 is provided with the liquid in-out mouth for connecting line of some groups of through front and rear walls, often group liquid in-out mouth includes an inlet 4 and a liquid outlet 5, described spool 2 is tabular, which is provided with some flowing holes 6, make spool 2 when different operating position, one or more flowing hole 6 on spool 2 is corresponding with a group on valve casing 1 or many group liquid in-out mouth positions, these liquid in-out mouths are made to be in opening state, and when spool 2 not having flowing hole 6 corresponding with the liquid in-out mouth position on valve casing 1, then controller is off state。
Described spool 2 is provided with three operating positions and is provided with 4 flowing holes 6, described valve casing 1 is provided with 4 groups of liquid in-out mouths, spool 2 is when the first operating position, controller is off state, when the second operating position, having two flowing holes 6 relative to answering with two groups of liquid in-out mouth positions, when three operating positions, another two flowing hole 6 is relative with two other group liquid in-out mouth position just should。This is set to 3-position 4-way structure, and the operating position of off state can also be located at interposition。
Described flowing hole 6 and described liquid in-out mouth are divided into upper and lower two row's arrangements, so can effectively shorten the length of valve。3-position 4-way structure, flowing hole 6 and liquid in-out mouth are divided equally up and down。During the first operating position, it is off state。During the second operating position, upper left and bottom right liquid in-out mouth are opened。During three operating positions, upper right and lower-left liquid in-out mouth are opened。
The position that the inwall of described valve casing 1 contacts with the front-back of described spool 2 is provided with sealant。Sealant adopts polytetrafluoro bronze guidance tape, has good sealing and high and low temperature resistance。
Fairlead 7 and sealing ring 8 it is provided with between described pull bar 3 and described valve casing 1。The plate body of spool 2 is configured to parallel two pieces up and down, and pull bar 3 is fixed on the centre of two boards shape body by the beam being connected with spool 2, and two boards shape body is separated, and is conducive to sealing。
Pull bar 3 can drive conversion between different operating position with servomotor by screw mandrel。
