Abstract

The utility model relates to a fluid commutator, which is arranged in a pipeline and is used for changing the fluid flow direction. The fluid commutator comprises a casing 3, a seal ring 4 and a seal gasket 5, wherein, the casing 3 is provided with an inlet hole 1 and an outlet hole 2. The utility model is characterized in that the inner of the casing 3 is fixed with an upper and a lower guide vanes 7 which are provided with guide holes 6, and a commutator plate 10 is arranged between the two guide vanes 7 and is provided with a guiding groove 8 and a toggle groove 9. The center of the casing 3 is also provided with a rotary shaft 11 which is provided with a toggle plug, and the toggle plug of the rotary shaft 11 is matched with the toggle groove 9 of the commutator plate 10. Compared with the prior commutators, the utility model has the advantages of easy commutation, labor saving, good tightness and long service life.

Description

A kind of fluid commutator

The utility model relates to a kind of fluid reversing device, and particularly a kind of being placed in the pipeline is in order to change the fluid commutator of fluid flow direction.

Being used for the reversing arrangement of fluid such as the shower commutator of Tap for bathtub at present all is stretching structure usually, change the flow direction of fluid with the sealing station that moves up and down lifting rod change " O " type O-ring seal, the commutator of this structure in use, the pressure of fluid acts directly on the sealing surface, when hydrodynamic pressure is big, the effect of this pressure has increased the resistance when sealing surface changes, and pull lift action is difficult during commutation.Though the manufacturer that has is a head it off, change the push pull maneuver of lifting rod into the spiral lifting action, the hydrodynamic pressure that does not still change sealing surface like this and born, the resistance of commutation is still very big, so effect and bad.

The purpose of this utility model is to provide a kind of commutation to be easy to fluid commutator.

The utility model is achieved in that a kind of fluid commutator, it comprises housing, seal ring, the sealing gasket of bringing the hole into and portalling, it is characterized in that: described housing internal fixation has the upper and lower guiding piece in tape guide hole, tape guide groove and the commutator segment of stirring groove are arranged between two guiding pieces, described housing center also is provided with the rotating shaft that band dial to be inserted, and the dialling to insert of rotating shaft matched with the groove of stirring of commutator segment.

The distribution that interlaces of the pilot hole of above-mentioned upper and lower guiding piece.

Above-mentioned guiding piece and commutator segment are ceramic fitting.

The utility model adopts three and has pilot hole, the mutual sealable guiding piece of groove, commutator segment, fluid reversing is carried out in rotation by commutator segment, because it is little that the rotation of commutator segment is influenced by hydrodynamic pressure, so fundamentally solved the problem that existing stretching structure commutator exists.

Guiding piece of the present utility model, commutator segment are ceramic plate, and ceramic plate rotates and is subjected to fluid pressure action little, and is easily laborsaving during use; And owing to the slide relative of having only in using between ceramic plate, and ceramic plate has good hardness, wear resistance, and this makes sealing surface not fragile, has improved the life-span of commutator; In addition, the impurity that contains in the fluid can be deposited in the pipeline in using, and fit tightly mutually between ceramic plate, impurity can not enter between faying surface, can not influence sealing effect, in sum, the utility model compares with existing commutator that to have a commutation easily laborsaving, good airproof performance, the characteristics of long service life.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1, the utility model embodiment's structural representation;

Fig. 2, working principle schematic representation of the present utility model;

Fig. 3, the utility model embodiment's scheme of installation.

Referring to accompanying drawing as can be known: a kind of fluid commutator, it comprises brings hole 1 into and portal 2 housing 3, seal ring 4, sealing gasket 5, it is characterized in that: described housing 3 internal fixation have the upper and lower guiding piece 7 in tape guide hole 6, tape guide groove 8 and the commutator segment 10 of stirring groove 9 are arranged between two guiding pieces 7, described housing 3 centers also are provided with the rotating shaft 11 that band dial to be inserted, and the dialling to insert of rotating shaft 11 matched with the groove 9 of stirring of commutator segment 10.

In this example, guiding piece 7 and commutator segment 10 are ceramic fitting.

Referring to Fig. 1,2 as can be known: the pilot hole 6 of the upper and lower guiding piece 7 in the present embodiment is the fan shaped borehole of two symmetries, and the pilot hole 6 of guiding piece 7 is vertical mutually up and down.Because the effect of seal ring 3, sealing gasket 4, fluid can only just can flow out by the pilot hole 6 of guiding piece 7, the guiding groove 8 of commutator segment 10; When the guiding groove on the commutator segment 10 8 alignd with the pilot hole 6 of last guiding piece 7, fluid was from the outflow of portalling; Rotating shaft 11 is rotated, and drives commutator segment 10 and rotates, and the guiding groove 8 on it is alignd with the pilot hole 6 of following guiding piece 7, and other parts of while commutator segment 10 seal up the pilot hole 6 of guiding piece 7, fluid under the outflow of portalling, thereby reach the purpose of fluid reversing.
