Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-valve body, 2-valve pocket, 3-valve pocket, 4-spherical valve core, 5-spring, 6-groove, 7-depression bar, 8-handwheel, 9-flexible rubber pipe, 10-liquid entering hole, 11-liquid outlet, 12-pars contractilis.
Embodiment
Below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
Shown in Fig. 1, a kind of flexible throttle valve, comprise valve body 1 and be socketed in the valve pocket 3 on valve body 1, valve body 1 is provided with the valve pocket 2 of perforation, valve pocket 2 two ends are respectively equipped with liquid entering hole 10 and liquid outlet 11, in valve pocket 2, be provided with flexible rubber pipe 9, in valve pocket 3, be provided with throttling controlling mechanism, throttling controlling mechanism comprises the spherical valve core 4 being located in valve pocket 3 and the depression bar 7 being meshed with spherical valve core 4, the end of depression bar 7 is provided with handwheel 8, clockwise rotate handwheel 8, can drive depression bar 7 to push spherical valve core 4, rotate counterclockwise handwheel 8, can drive depression bar 7 that spherical valve core 4 is outwards separated, wherein, flexible rubber pipe 9 is provided with the pars contractilis 12 that deformation extending amount is greater than flexible rubber pipe 9, valve body 1 is provided with the groove 6 connecting with valve pocket 2 in the position corresponding with pars contractilis 12, 4 points of spherical valve cores are located in the grooves on two sides 6 of valve body 1 and connect with described pars contractilis.
When enforcement, be provided with spring 5 in valve pocket 2, the two ends of spring 5 connect with pars contractilis 12 respectively, can prevent that spherical valve core 4 forms excessive compression to flexible rubber pipe 9.In order better to protect flexible rubber pipe 9, the both ends of the surface of spring 5 are circular arc, suitable with the arc inner wall of flexible rubber pipe 9.
The working principle of this flexibility throttle valve is: under original state, spherical valve core 4 does not form extruding to flexible rubber pipe 9, throttling cross section in valve pocket 2 does not change, the flow rate of liquid at liquid entering hole 10 places is identical with the flow rate of liquid at liquid outlet 11 places, in the time of needs throttling, clockwise rotate handwheel 8, drive depression bar 7 to push spherical valve core 4, make the spherical valve core 4 of valve body 1 both sides mutually close, flexible rubber pipe 9 is formed to extruding, reduce the throttling cross section of valve pocket 2 at this place with this, reduce the flow that liquid passes through, play throttling action.In adjustment process, because the deformation extending amount of pars contractilis 12 is greater than the deformation extending amount of flexible rubber pipe 9, therefore, flexible rubber pipe 9 can bear significantly repeated deformation compression in the position of this pars contractilis 12.Spring 5 can prevent that spherical valve core 4 from causing excessive compression to flexible rubber pipe 9, formed duplicate protection by both modes to flexible rubber pipe 9.In the time that needs tune up flow, rotate counterclockwise handwheel 8, can drive spherical valve core 4 to be separated from each other, increase the throttling cross section of valve pocket 2 at this place.
This flexibility throttle-valve structure is simple, on flexible rubber pipe, deformation is provided with the pars contractilis that extending amount is large in position frequently, can bear significantly repeated deformation compression, simultaneously, built-in spring can avoid flexible rubber pipe to be subject to overburdening extruding, has extended the working life of flexible rubber pipe.In addition, also have simple in structure, the feature that throttling control mode is simple.
