Description

Replace part flow arrangement

The utility model relates to a kind of alternately part flow arrangement, is about to a fluid streams and is divided into several strands according to certain rules.

Prior art normally realizes that by the switch of several valves of control gear control its shortcoming is: the switch of frequent operation valve diminishes the life-span of valve.

The purpose of this utility model provides a kind of device of being realized the fluid alternation by single structure.

Be used to realize a kind of alternately part flow arrangement of the utility model purpose, comprise the female pipe of fluid, rotating cylinder, fluid branches, motor, axle, bearing, fluid branches links to each other with the female pipe of fluid, rotating cylinder places in the female pipe of fluid, have split-flow opening according to certain rule on the rotating cylinder, split-flow opening can be connected with fluid branches when rotating cylinder rotates, and rotating cylinder links to each other with motor by axle.

Alternately part flow arrangement of the present utility model has characteristics such as simple in structure, easy to use, that the life-span is long.Can be used for the shunting of gas and liquid, clean air feed, fountain water supply or the like as filter.

Describe the utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is the utility model first embodiment's a sectional drawing.

Fig. 2 is the utility model second embodiment's a sectional drawing.

Fig. 3 is the utility model the 3rd embodiment's a sectional drawing.

The utility model proposes a kind of alternative flow by-pass apparatus (referring to Fig. 1,2,3), mainly by the fluid mother The compositions such as pipe 1, rotating cylinder 2, fluid branches, motor 7, axle 12, bearing, rotating cylinder 2 place the female pipe 1 of fluid In, fluid branches links to each other with the female pipe 1 of fluid, has diffluence pass 9, diffluence pass according to certain rule on the rotating cylinder 2 9 can connect with fluid branches when rotating cylinder 2 rotation, and termination 10 and the axle 12 of rotating cylinder 2 are used bolt by flange 11 4 connect, and axle 12 is connected with blind plate 6 by associated sealing arrangement for bearings 14, and blind plate 6 is bolted on the fluid mother On the pipe flange 5, rotating cylinder 2 can be driven by motor 7 by axle 12 and rotate according to certain frequency. Operation principle: electricity Machine 7 is by axle 12 driven rotary, and when rotating cylinder 2 diffluence pass 9 were connected with fluid branches 3, fluid is female managed in 1 Fluid incoming fluid arm 3, when rotating cylinder 2 diffluence pass 9 are connected with fluid branches 8, the stream in the female pipe 1 of fluid Body incoming fluid arm 8 so moves in circles, and has realized the alternately shunting of fluid. The rotating speed of regulating electric machine Can change frequency alternately.

Figure 1 shows that two fluid arms are oppositely arranged in same plane perpendicular to the female pipe of air 1 center line, diffluence pass 9 is opened in the situation of the half cycle of rotating cylinder 2 in the same plane perpendicular to the female pipe of air 1 center line of fluid branches, Fig. 2,3 is depicted as fluid branches and arranges in the same way in the plane of the female pipe of air 1 center line in different vertical, and diffluence pass 9 is respectively same flat perpendicular to air mother pipe 1 in each fluid branches

Tiltedly to the situation of the half cycle that is opened in rotating cylinder 2, this moment is because rotating cylinder 2 is longer in the face, rotating cylinder 2 away from One end of motor can directly arrange bearing 15 (such as Fig. 2) or be fixed on (such as Fig. 3) on the axle 12, and axle 12 is far away End from motor can be supported on the female pipe of fluid 1 inwall by bearing 17, carriage 16. Between the fluid branches Can be oppositely arranged (such as Fig. 1), (referring to Fig. 2,3) also can be set in the same way or establish according to certain angle Put. Rotating cylinder 2 diffluence pass 9 according to different rules offer can make fluid branches not overlapping, replace incessantly Open (such as Fig. 1,2,3), or the time and alternately open, the time and simultaneously open-minded, the time and alternately open, the time And close etc. simultaneously. Motor 7 can link to each other with axle 12 with variable-frequency governor control or by speed changer. Rotating cylinder 2 can make with plastics or metal etc., the female pipe of rotating cylinder 2 outer walls, fluid 1 inwall should be smooth and the two gap should As far as possible little, the female pipe of rotating cylinder 2, fluid 1 should be taked anti-corrosion measure during for metal. Also can use hand as required Wheel replaces motor 7 to carry out manual operation.

The utility model is described in further detail to utilize embodiment below:

Embodiment: a kind of device of air (as Fig. 1) that alternately divides

This device is mainly by the female pipe 1 of air, rotating cylinder 2,

air arm

3 and 8, motor 7, axle 12, compositions such as bearing, rotating cylinder 2 places in the female pipe 1 of air, air arm 3 and air arm 8 are oppositely arranged in same plane perpendicular to the female pipe of air 1 center line and are connected on the female pipe 1 of air, in the same plane of air arm, have half cycle split-flow opening 9 on the rotating cylinder 2 perpendicular to the female pipe of air 1 center line, the termination 10 of rotating cylinder 2 is connected by flange 11 usefulness bolts 4 with axle 12, axle 12 is connected with blind plate 6 by associated sealing arrangement for bearings 14, blind plate 6 is by being bolted on the female pipe flange 5 of fluid, rotating cylinder 2 can be driven according to the certain frequency rotation by motor 7 by axle 12, and motor 7 is controlled by variable-frequency governor.Working principle: motor 7 is by axle 12 driven rotary, when rotating cylinder split-flow opening 9 and air arm 3 have just begun to connect, air in the female pipe 1 of air begins to flow into air arm 3, air arm 8 begins to close, when rotating cylinder split-flow opening 9 is relative with air arm 3 fully, air mass flow in the air arm 3 reaches maximum value, and air arm 8 is closed fully, and the air mass flow in the air arm 8 reaches minimum value; When rotating cylinder split-flow opening 9 and air arm 8 have just begun to connect, air in the female pipe 1 of air begins to flow into air arm 8, air arm 3 begins to close, when rotating cylinder split-flow opening 9 is relative with air arm 8 fully, air mass flow in the air arm 8 reaches maximum value, air arm 3 is closed fully, and the air mass flow in the air arm 3 reaches minimum value, has realized alternately dividing the purpose of gas and so forth.Regulate rotating speed of motor by variable-frequency governor and can change frequency alternately.
