The sectional view of the coaxial rotating valve that Fig. 1 provides for the embodiment of the present invention one; Fig. 2 is the stereogram of Fig. 1.As shown in Figure 1 and Figure 2, the coaxial rotating valve that the embodiment of the present invention provides comprises valve body 1, in valve body 1, be provided with valve pocket, on valve body 1, be provided with first valve opening 10 and at least one the second valve opening 5, in valve pocket, be rotatably connected to spool 2, the core hole of spool 2 and the first valve opening 10 coaxial communication, and core bore dia is more than or equal to the diameter of the first valve opening 10.
Coaxial rotating valve provided by the invention, the core bore dia of its spool is more than or equal to the diameter of the first valve opening 10, make the inwall in core hole and the inwall coplanar of the first valve opening 10, or the inwall of valve opening is positioned at the outside of the inwall of the first valve opening 10, thereby prevent that granular and/or the cotton-shaped dirt of line in fluid from easily entering between spool 2 and valve body 1, avoided occurring dirty stifled problem.
Further, based on above-described embodiment, in order to make to reach good sealing effect between spool 2 and valve body 1, between spool 2 and valve body 1, be provided with seal.
Further, based on above-described embodiment, spool 2 is cylinder spool, is provided with first through hole 7 that can be communicated with the second valve opening 5 on the sidewall of cylinder spool.By rotational valve core 2, the first through hole 7 is communicated with the second valve opening 5, open this coaxial rotating valve, otherwise close this coaxial rotating valve.When this coaxial rotating valve is multiple-way valve, by rotational valve core 2, come selectivity to open and close a certain path.It is simple in structure that spool 2 adopts cylinder spool to have, and is convenient to processing, reliable advantage.
Because spool 2 adopts cylinder spool, the inwall coplanar of the inwall in the core hole of cylinder spool and the first valve opening 10, makes the flux of this coaxial rotating valve larger in the present embodiment.Compare in the situation that flux is identical with existing valve, can reduce the volume of this coaxial rotating valve, make this coaxial rotating valve can realize miniaturization, be also conducive to reduce costs.
Further, based on above-described embodiment, the first through hole 7 and the second valve opening 5 coaxially arrange, and the diameter of the second valve opening 5 is greater than the diameter of the first through hole 7.The first valve opening 10 is as liquid entering hole, the second valve opening 5 is as liquid port, because the diameter of the second valve opening 5 is greater than the diameter of the first through hole 7, the edge of 7 pairs of the second valve openings 5 of the first through hole has formed certain effect of blocking, prevent that granular and/or the cotton-shaped dirt of line in fluid from easily entering between Sealing and valve body 1, avoided occurring dirty stifled problem.
Further, based on above-described embodiment, valve pocket can adopt circular hole valve pocket, valve pocket and the first valve opening 10 form shoulder hole, and the diameter of valve pocket is greater than the diameter of the first valve opening 10, at valve pocket and the first valve opening 10 link position places, formed step like this, this step is conducive to prevent that the granular and/or the cotton-shaped dirt of line that are blended in the liquid flowing into from the first valve opening 10 from entering between spool 2 and valve body 1, has avoided occurring dirty stifled problem.
Further, based on above-described embodiment, in order to improve sealing effect, seal adopts sealed pipe 3, and sealed pipe 3 fixed covers are loaded on the outside of cylinder spool, and the sidewall of sealed pipe 3 is provided with the second through hole 6 being communicated with the first through hole 7.Sealed pipe 3 rotates with the rotation of spool 2, forms the face that is sealed and matched between sealed pipe 3 and valve body 1, prevents fluid seepage.In addition, above-mentioned step is also conducive to prevent that the granular and/or the cotton-shaped dirt of line that are blended in the liquid flowing into from the first valve opening from entering between sealed pipe 3 and valve body 1, has avoided occurring dirty stifled problem.
The sectional view of the coaxial rotating valve that Fig. 3 provides for the embodiment of the present invention two.As shown in Figure 3, the difference of this embodiment and above-described embodiment is mainly, sealed pipe 3 is rotatably set in the outside of cylinder spool, and sealed pipe 3 is fixedly connected with valve body 1, and the sidewall of sealed pipe 3 is provided with the second through hole 6 being communicated with the second valve opening 5.The first through hole 7 of spool 2 in each the second valve opening 5 positions, is provided with the second through hole 6, so that can be communicated with the second valve opening 5.During work, spool 2 rotates with respect to sealed pipe 3, between spool 2 and sealed pipe 3, forms motive sealing face, has good sealing effect, prevents that liquid is from revealing between spool 2 and sealed pipe 3.
Further, based on above-described embodiment, in order to realize automatic control, be connected with drive motor 9 on spool 2, drive motor 9 is positioned at valve pocket outside.Drive motor 9 can adopt reducing motor, and the rotating shaft of drive motor 9 is fixedly connected with the bottom of cylinder spool, and the rotation by drive motor 9 is with the rotation of movable valve plug 2.
Further, based on above-described embodiment, the outside of drive motor 9 is set with motor cover 8, and motor cover 8 is cylinder motor cover, and the bottom of cylinder motor cover offers third through-hole, and the rotating shaft of drive motor 9 is arranged in third through-hole.The bottom of motor cover 8 has to drive motor 9 effect of blocking, and prevents fluid seepage in valve and enters into drive motor 9 inside, and drive motor 9 is caused to damage.
Further, based on above-described embodiment, valve body 1 comprises tubular shape main body, is communicated with at least one valve pipe 4 on the sidewall of tubular shape main body, and the interior bone of valve pipe 4 is the second valve opening 5.Adopt above-mentioned valve body 1 structure, make this coaxial rotating valve arrangement simply compact, lighter weight, cost of production is low.
The stereogram of the coaxial rotating valve that Fig. 4 provides for the embodiment of the present invention three.As shown in Figure 4, take the axis of tubular shape main body as rotating center is evenly provided with a plurality of valve pipes 4, correspondingly, the each angle of rotating of motor-driven valve core is uniformly within the scope of 360 °, angle of its each rotation be 360 with the business of valve pipe 4 numbers.The present embodiment shows the structure that even circumferential arranges three valve pipes 4, is now four-way valve, by cylinder spool, optionally connects a certain valve pipe 4.Certainly, according to actual needs, the valve pipe 4 of other quantity can also be set.Four valve pipes 4 are for example set, and are now five-way valve; Five valve pipes 4 are set, and are now six-way valve, and logical more than arranging the rest may be inferred.A plurality of valve pipes 4 are non-homogeneous setting in a circumferential direction also, and correspondingly, the angle that motor-driven valve core rotates is also heterogeneous, and the each rotation angle of spool can be the angle of adjacent two valve pipe 4 axis.
In actual use, the first valve opening 10 can be mutually vertical with the axis of the second valve opening 5.
The coaxial rotating valve arrangement that the embodiment of the present invention provides is simply compact, and preparation process is easy, has reduced cost of production.
Finally it should be noted that: above embodiment only, in order to technological scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to previous embodiment, those of ordinary skill in the art is to be understood that: its technological scheme that still can record aforementioned each embodiment is modified, or part technical characteristics is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technological scheme.
