First embodiment
As shown in Figure 1, the self-opening type whitewashing switch 100 includes an ontology 110, a spring 120 and a motion stops 130.
Ontology 110 includes first end and second end, and the first end of ontology 110 is located at one end on 110 length direction of ontology,
The second end of ontology 110 is located at the other end on 110 length direction of ontology, wherein is provided on the first end end face of ontology 110
One inlet opening 111, inlet opening 111 have extended to form cavity 112 to the second extreme direction of ontology 110, which does not penetrate this
The second end of body 110, wherein cavity 112 is divided into first from the second extreme direction of first end to the ontology 110 of ontology 110
Channel 1121, second channel 1122 and third channel 1123, the first passage 1121, second channel 1122 and third channel 1123
It is sequentially communicated, the first passage 1121 is corresponding with inlet opening 111, wherein the diameter of first passage 1121 is less than third channel
1123 diameter, second channel 1122 is in a circular table shape, it will be appreciated by persons skilled in the art that this is in a circular table shape second logical
The upper bottom surface in road 1122 corresponds to first passage 1121, and bottom surface corresponds to third channel 1123.The second end end face of the ontology 110
On be provided with several fluid holes 113, fluid hole 113 is connected with cavity 112, in the present embodiment, the number of the fluid hole 113
Amount is four, which can circumference array setting.It in addition can be by changing 113 axis of fluid hole and 110 axis of ontology
Angle between line, and then realize the change of spray angle, in the present embodiment, 113 axis of two of them fluid hole and ontology
110 axis are parallel, i.e. realization horizontal-jet, and the angle between 113 axis of another two fluid hole and body axis is 8 °
8 ° of injections inwardly or outwardly are realized, so that cutting range is more.It is worth noting that, as needed, it can be to multiple fluid holes 113
In part blocked, to choose different whitewashing directional combinations as needed, blocking includes by bolt and liquid out
Hole 113 is threadedly coupled, therefore, the settable internal screw thread of fluid hole 113.
Spring 120 is located in cavity 112, is particularly located at third channel 1123.
Motion stops 130 are located in cavity 112, and motion stops 130 block second channel under the reset force effect of spring 120
1122, the liquid (including mud) for entering inlet opening 111 can not pass through from second channel 1122, and can not be from fluid hole 113
It sprays.When liquid can push motion stops 130 to overcome 120 elastic force of spring mobile, which can be from second channel 1122
Be moved to third channel 1123, open second channel 1122, at this point, liquid can from motion stops 130 and third channel 1123 it
Between flow through, until from fluid hole 113 spray.In the present embodiment, motion stops 130 are in sphere shape.Those skilled in the art can be with
Understand, the size of hydraulic pressure can directly influence the blowing force of the water outlet of fluid hole 113, for example, when hydraulic pressure can push work
Dynamic plug 130 from second channel 1122 completely into third channel 1123 when, at this point, the blowing force that fluid hole 113 is discharged is maximum.And
When hydraulic pressure cannot push motion stops 130 mobile, liquid will not be discharged in fluid hole 113.
As shown in Figure 1, self-opening type whitewashing switch 100 can connect external equipment 200 by screw thread 114, which can be
Two sections, and it is located at the both ends of ontology 110.
Second embodiment
As shown in Fig. 2, the difference of the self-opening type whitewashing switch second embodiment and first embodiment is motion stops,
In the present embodiment, the motion stops 130 ' are in a circular table shape, and shape is adapted with second channel 1122, as shown in figure 3, being in rotary table
Through-hole 131 ' is provided in the motion stops 130 ' of shape, the upstream end of through-hole 131 ' is located on the side wall of motion stops 130 ', through-hole
131 ' outlet end is located on the bottom surface of motion stops 130 '.When hydraulic pressure cannot push motion stops 130 ' mobile, at this point, motion stops
130 ' side wall is bonded with second channel 1122, i.e. the upstream end of through-hole 131 ' does not have exposed, i.e., fluid hole 113 will not discharge liquor
Body, when hydraulic pressure can push motion stops 130 to enter third channel 1123 from second channel 1122.At this point, through-hole 131 '
Upstream end is exposed, and liquid until spraying from fluid hole 113, can effectively prevent mud to generate reaction force by through-hole 131 ',
And then reduce cutting effect.
In the present embodiment, the quantity of through-hole 131 ' is 6, and is arranged along the circumference array of motion stops 130 '.
