Description

A kind of reversible interface device of pump

The utility model belongs to a kind of interface device, relates to a kind of reversible interface device that can match with various pumps.

A large amount of at present pumps that use after the flow direction of liquid, if desire its flow direction of conversion, then must be switched the import and export position of outer pipeline and pump and could realize that in reversed process, liquid easily runs off in having determined outer pipeline, thereby cause waste and befouling environment.

The purpose of this utility model provides a kind of reversible interface device of pump, this device fundamentally solved keep pump with outside under the constant state of pipeline Placement, can be used for the flow direction of any conversion fluid.

For achieving the above object, the utility model is taked following design proposal: the reversible interface device is made up of four pipe valves and four Y-piece roads, and described pipe valve is connected with the Y-piece road is corresponding mutually, constitutes the loop that has four interfaces; Have two interfaces to be connected with the import and export of pump respectively in these four interfaces, two interfaces connect outer pipeline respectively in addition; Described Y-piece Lu Yousan fork, wherein two forks are connected with corresponding two pipe valves, and another fork is as one of above-mentioned interface, connection pump or outer pipeline.

The fluid reversing device of reversible interface device described in the utility model and other kind is essentially different, because it is made up of four pipe valves and four Y-piece roads, so whole outer pipeline no matter Any shape all can ensure the reliability of fluid reversing, this apparatus structure simplicity of design simultaneously, easy to install, flexible operation, not only improved working efficiency, and avoided the pollution of the waste of flowing material and special flowing material environment.

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 3-Fig. 4 is a working procedure explanation schematic representation of the present utility model

As shown in Figure 1, the reversible interface device of pump is made up of 5,6,7,8 on 1,2,3,4 and four Y-piece roads of four pipe valves.Described pipe valve is connected with the Y-piece road is corresponding mutually, constitutes the loop that has four interfaces 9,10,11,12.In four interfaces, have two interfaces to be connected with the import and export of pump respectively, two interfaces then connect two outer pipelines respectively in addition.Y-piece Lu Yousan fork, wherein two forks are connected with corresponding two pipe valves, and another fork is as one of above-mentioned interface, connection pump or outer pipeline.As shown in Figure 1, above-mentioned each pipe valve is connected in the direction of the clock with the Y pipeline and the order of arranging is followed successively by: pipe valve 1, Y-piece road 6; Pipe valve 3, Y-piece road 8; Pipe valve 2, Y-piece road 5; Pipe valve 4, Y-piece road 7.Wherein interface 9 one of Y-piece road 5 that is positioned at 4 at pipe valve 2 and pipe valve sticks; One of Y-piece road 6 that interface 10 is positioned at 3 at pipe valve 1 and pipe valve sticks; Stick for one of the Y-piece road 7 of interface 11 between pipe valve 1 and pipe valve 4; Stick for one of the Y-piece road 8 of interface 12 between pipe valve 2 and pipe valve 3.

As shown in Figure 2,13 is pump among the figure, and 14 is pump intake, and 15 is the exhaust port of pump, and I, II are respectively outer pipeline, and the other end of outer pipeline then connects different containers respectively.As seen from the figure, during use, interface 9 is connected with outer pipeline II, and interface 10 is connected with outer pipeline I, and interface 11 is connected with the suction port 14 of pump 13, and interface 12 is connected with the exhaust port 15 of pump 13.

The working principle of reversible interface device is as follows: pipeline I outside making, fluid in the II is made forward flow, must do following operation to four pipe valves of reversible interface device: open pipe valve 1 and pipe valve 2, close pipe valve 3 and pipe valve 4, primer pump 13 then, then liquid passes through interface 10 inspirations from an end of outer pipeline I, through Y-piece road 6, pipe valve 1, Y-piece road 7, suck from the suction port 14 of pump 13, discharge from the exhaust port 15 of pump 13 again, pass through Y-piece road 8 again, pipe valve 2, Y-piece road 5, discharge from the other end of outer pipeline II by interface 9 at last, thereby finish fluid pipeline I outside, forward flow in the II, as shown in Figure 3; Pipeline I outside making, fluid in the II is made reverse flow, must do following operation to four pipe valves of reversible interface device: open pipe valve 3 and 4, close pipe valve 1 and 2, primer pump 13 then, then fluid passes through interface 9 inspirations from an end of outer pipeline II, through Y-piece road 5, pipe valve 4, Y-piece road 7, suck from the suction port 14 of pump 13, exhaust port 15 through pump 13 is discharged, pass through Y-piece road 8 again, pipe valve 3, Y-piece road 6, discharge by interface 10 from the other end of outer pipeline I at last, thereby finish fluid pipeline I outside, reverse flow in the II, as shown in Figure 4.

Be not difficult to find out by operation four pipe valves of above docking port device, when the flow direction of the fluid in outer pipeline I, the II changes, and fluid is by the suction and the not change of discharge direction of pump 13, therefore fundamentally solved under keeping the constant state of pump and outer pipeline Placement, arbitrarily the mobile direction of conversion fluid.
