Description of drawings
Fig. 1 shows the schematic perspective view according to an embodiment's of the utility model rotary valve.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technological scheme of the utility model.In specification, same or analogous drawing reference numeral is represented same or analogous parts.Followingly the explanation of the utility model mode of execution is intended to the overall model utility design of the utility model is made an explanation, and is not to be understood that and is a kind of restriction the utility model with reference to accompanying drawing.
Fig. 1 shows the rotary valve 100 according to a kind of embodiment of the utility model.Said rotary valve 100 comprises valve body 1 and spool 2.Said valve body 1 is provided with valve opening 11, and can be communicated with the fluid line (not shown) through said valve opening 11.Spool 2 is contained at least in part in the valve body 1 and with said valve body 1 and is rotatably assorted.Spool 2 opens or closes rotary valve 100 through the rotation with respect to valve body 1.In an example, spool 2 can be contained in the valve body 1 fully.In another example, spool 2 also can partly be contained in the valve body 1, and for example, spool 2 can comprise elongated stem (also can be described as valve rod), and this bar portion exposes from valve body 1 to be used to connect external components such as handle.As shown in the figure, the side of spool 2 is provided with spring eye 21, and said spring eye 21 is used to hold holddown spring 5.Though two spring eyes 21 have been shown among Fig. 1, this only is exemplary, and one or more spring eye 21 also can be set.Holddown spring 5 can provide impacting force so that the inwall of spool 2 and valve body 1 is adjacent to.
Because it is the most outstanding that the escape of liquid problem is at rotary valve 100 under the situation of closed condition; So; In one embodiment; The direction that can when rotary valve 100 is in closed condition, make the impacting force that holddown spring 5 provided is towards the valve opening that is closed 11, and this can realize through the direction that part or all of spring eye 21 is set.Like this, just can prevent better that fluid leaks via the slit of valve opening 11 when rotary valve 100 is in closed condition.Generally speaking, the arranged direction of spring eye 21 is consistent with the direction of the impacting force that holddown spring 5 is provided, so can the arranged direction of spring eye 21 be arranged to towards the valve opening 11 that will when rotary valve 100 is in closed condition, be closed.Yet this not necessarily also can adopt other arrangement, if the direction that will guarantee the impacting force that holddown spring 5 is provided when rotary valve 100 is in closed condition towards the valve opening that is closed 11.
In other embodiment, the direction of the impacting force that holddown spring 5 is provided also can be arranged to towards other direction, as long as the spool 2 and the inwall of valve body 1 are compressed.As an example, the direction of the impacting force of holddown spring 5 can be arranged perpendicular to the spin axis of spool 2.Can utilize the impacting force of holddown spring 5 so most effectively.
As shown in the figure, spool 2 offers circulation groove 22.When rotary valve 100 is in open mode, thereby ducted fluid can flow through from circulation groove 22 and can pass through from valve body 1.Spool 2 can change the relative position of valve opening 11 and circulation groove 22 with respect to the rotation of valve body 1, thereby control flows is crossed the flow of the fluid of valve body 1.That is to say that the flow of the fluid that from circulation groove 22, flows through depends on the rotational position of spool 2 with respect to valve body 1.Yet, this not necessarily, those skilled in the art can adopt any known alternate manner in related domain to realize the opening/closing control and the flow control of 2 pairs of rotary valves 100 of spool.
In one embodiment, spring eye 21 can be a blind hole, and holddown spring 5 can impose on spool 2 with impacting force through the extruding to the blind hole bottom.A holddown spring 5 can be held in each spring eye 21, also a plurality of holddown springs 5 can be held according to circumstances.In an example, holddown spring 5 can be cylindroid helicalcoil compression spring.
In one embodiment, rotary valve 100 can also comprise buffering ball 3.Buffering ball 3 on the action direction of holddown spring 5 between the inwall of said holddown spring 5 and valve body 1, directly contact with the inwall of valve body 1 with the end that prevents holddown spring 5.The existence of buffering ball 3 can directly be transformed into holddown spring 5 the contacting of inwall of buffering ball 3 and valve body 1 with the friction of the inwall of valve body 1.Because the surface of buffering ball 3 so be difficult for concentrating of generation power, can reduce the wearing and tearing of valve body 1 relative to level and smooth and can rotate.Buffering ball 3 can be a rigid ball, is for example processed by stainless steel.
In one embodiment, rotary valve 100 can also comprise catch 4.Catch 4 on the action direction of holddown spring 5 between said holddown spring 5 and buffering ball 3.The existence of catch 4 can prevent that buffering ball 5 from snapping onto in the holddown spring 5.Catch 4 also can for example be processed by stainless steel.
In one embodiment, valve body 1 is provided with spool bore 12.One end of spool 2 can expose from spool bore 12.For spool bore 12 is sealed, rotary valve 100 can also be provided with gland 6.Gland 6 forms sealing with spool bore 12 sealing and with the inwall of valve body 1, in case fluid is leaked from spool bore 12.The said end that spool 2 exposes from spool bore 12 can pass and seal with gland 6 formation from gland 6.For example; Gland 6 can be arranged to cylindrical body (or cylindrical shape) shape of a center drilling; As shown in Figure 1, its inner wall surface is provided with the annular recess that accommodates seal ring, is used for forming sealing with spool 2; And the outer wall surface of gland 6 also is provided with the annular recess that accommodates seal ring, is used for forming sealing with valve body 1.Gland 6 can be made of copper.
In one embodiment, rotary valve 100 can also comprise the indicating device 7 that is installed on the valve body 1, is used to indicate the rotational position of spool 2 with respect to valve body 1.For example, indicating device 7 can be provided with comprehensive visual pointer and scale, so that the user can observe the rotational position of spool 2 with respect to valve body 1 easily from all directions and angle, and then definite rotary valve 100 residing states.As shown in the figure, indicating device 7 can be mounted on the valve body 1 through the groove of valve body 1 upper end-face edge.Yet this not necessarily, and indicating device 7 can otherwise be installed on the valve body 1 according to the use needs, as long as can realize deixis.Indicating device 7 can be assembled into by working of plastics.
In one embodiment, rotary valve 100 can also comprise handle 8.Handle 8 is connected with spool 2 at the end away from valve body 1 of spool 2.The user can drive spool 2 easily through handle with sleeve 8 and rotate with respect to valve body 1.Handle 8 can be provided with the plane that cooperates with the end surface of spool 2, to improve itself and spool 2 connection stability and reliability.
In one embodiment, valve body 1 for example can be become by the DZR copper with spool 2.
It will be appreciated by those skilled in the art that above-mentioned various embodiment can make up each other.For example, as shown in Figure 1, the end that spool 2 exposes from the spool bore 12 of valve body 1 can pass gland 6, indicating device 7 successively, and then is connected with handle 8.
Though in conjunction with accompanying drawing the utility model is illustrated, disclosed embodiment is intended to the utility model preferred implementation is carried out exemplary illustration in the accompanying drawing, and can not be interpreted as a kind of restriction to the utility model.
Though some embodiments of the utility model general plotting are shown and explain; Those skilled in the art will appreciate that; Under the situation of principle that does not deviate from this overall model utility design and spirit; Can make a change these embodiments, the scope of the utility model limits with claim and their equivalent.
