Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
As shown in Figures 1 to 7, a kind of modified node method of switch control rule valve kit, comprise valve body 1, the spool 2 for control switch is provided with in described valve body 1, the middle part of described valve body 1 is connected with and controls sleeve pipe 3, the running shaft 4 be connected with described spool 2 is provided with in described control sleeve pipe 3, described control sleeve pipe 3 offers restriction screens 31, described running shaft 4 is connected with the limiting component 41 stretching into described restriction screens 31, also comprises and can stretch into described control sleeve pipe 3 for twisting the opening assembly 5 of described running shaft 4, this switch control rule valve kit in use, stretch in described control sleeve pipe 3 by opening assembly 5, and be socketed on the outer end of described running shaft 4, by twisting certain angle clockwise or counterclockwise, this switching control pilot can be opened or closed, when not using, described opening assembly 5 is taken out, described opening assembly 5 is positioned over the place that child cannot get, so namely, switching control pilot cannot be opened, and child also cannot touch running shaft 4, in sum, this switch control rule valve kit has special opening structure, thus improve the Security of use greatly, and it is easy to use, structure is simple.
In the technical program, in order to improve the easy to carry of this opening assembly 5 further, specifically, described opening assembly 5 comprises handle part 51 and bar body 52, one end of described bar body 52 is connected with handle part 51, and the other end of described bar body 52 is provided with the inserted part 53 that can be socketed with described running shaft 4.During use, this opening assembly 5 is taken out, make inserted part 53 and running shaft 4 clamping, in the technical program, because described running shaft 4 is connected with the limiting component 41 stretching into described restriction screens 31, this inserted part 53 also can arrange a recess, utilize described limiting component 41 to snap in described recess, the rotation of driven rotary axle 4 can be realized, simultaneously, described handle part 51 can also open a string hole, key ring is carried with together by this opening assembly 5.
Alternatively, the cross section of described running shaft 4 is polygonal to the technical program, and described inserted part 53 is provided with the inner chamber 54 with the outer end clamping of described running shaft 4.Like this, inserted part 53 described in the technical program need only be mated with the polygonal of described running shaft 4, when described inserted part 53 and running shaft 4 be socketed rotate time, also can realize the rotation of driven rotary axle 4 simultaneously.
In order to improve the working life of this switching control pilot further, the outer installment of described control sleeve pipe 3 has outside thread 32, also comprises the safety enclosure 6 be spirally connected with described control sleeve pipe 3, and described safety enclosure 6 offers the limiting holes 61 that can stretch into for described opening assembly 5.Like this, under the protection of safety enclosure 6, other hard object not only can be avoided the accident collision of this switching control pilot, and, can also prevent from utilizing other instrument to turn running shaft 4.
Meanwhile, when not using, in order to prevent foreign matter from entering in safety enclosure 6, the inner side of described limiting holes 61 is hinged with switch baffle plate 62, and described switch baffle plate 62 closes described limiting holes 61 by torsion spring.After described opening assembly 5 is extracted, under the effect of torsion spring, described switch baffle plate 62 is worked as described limiting holes 61 and is closed; When described opening assembly 5 inserts, opening assembly 5 overcomes the active force of torsion spring, backs down switch baffle plate 62, such structure, can effectively prevent foreign matter from entering inside.
In the technical program, described spool 2 is ball core body, and described ball core body offers the through hole 21 communicated with described valve body 1 both sides.When described running shaft 4 drives spool 2 to turn to several angle, described through hole 21 communicates with two side runners of described valve body 1, when described running shaft 4 drives spool 2 to rotate backward several angle, described through hole 21 is misplaced with two side runners of described valve body 1, thus realizes closing.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
