fig. 3 is the phantom in B-B direction in Fig. 1.
wherein, 1, valve rod; 2, drive plate; 21, lug boss; 22, the second fluted disc; 3, handwheel; 31, the first fluted disc; 4, stage clip; 5, ballast dish; 6, pointer; 7, nut.
Embodiment
below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, can be easier to make advantage of the present utility model and feature be understood by those skilled in the art.
fig. 1-3 is depicted as a kind of valve handle.Shown in composition graphs 1-3, valve handle comprises drive plate 2, handwheel 3, elastic component, ballast dish 5 and pointer 6 from bottom to top successively.Drive plate 2 is fixedly connected with the valve rod 1 of valve body, and adopt square shaft valve rod 1 and drive plate 2 to be rigidly connected in the present embodiment, when drive plate 2 rotates, valve rod 1 can rotate thereupon.The second fluted disc 22 that the upper side of drive plate 2 has the lug boss 21 in column protruding upward, encloses around lug boss 21 1.Handwheel 3 is sheathed on lug boss 21 and also can rotates around the center line of lug boss 21, the downside of handwheel 3 has the first fluted disc 31 matched with the second fluted disc 22.The top of lug boss 21 has screw thread, ballast dish 5 offers the mounting hole passed for lug boss 21, in mounting hole, there is internal thread, ballast dish 5 is connected with lug boss 21 screw-thread fit, when rotating ballast dish 5, ballast dish 5 moves towards or away from handwheel 3, and the upper end of lug boss 21 is fixedly connected with for carrying out spacing to ballast dish 5 with a nut 7.Elastic component is stage clip 4 and is sheathed on lug boss 21, and stage clip 4 top is located between handwheel 3 and ballast dish 5.Pointer 6 is fixedly installed on lug boss 21 upper end, and the upper surface of ballast dish 5 is provided with a circle ballast power numerical value, pointer 6 is used to indicate ballast power numerical value.
stage clip 4 is in compressive state to provide a ballast power to handwheel 3, and handwheel 3 compresses drive plate 2 under the ballast power effect of stage clip 4, and the first fluted disc 31 and the second fluted disc 22 are meshed.There is a slipping torque between first fluted disc 31 and the second fluted disc 22, this slipping torque is relevant to the ballast power that the frictional force between the first fluted disc 31 and the second fluted disc 22, stage clip 4 are carried on handwheel 3, this slipping torque and maximum operational torque.When putting on the operational torque on handwheel 3 and being greater than this slipping torque, the first fluted disc 31 and the second fluted disc 22 are separated, and handwheel 3 rotates and drive plate 2 keeps transfixion.And when putting on the operational torque on handwheel 3 and being less than or equal to slipping torque, the first fluted disc 31 keeps being meshed with the second fluted disc 22, drive plate 2 rotates with handwheel 3 and rotates.Like this, when steering force is excessive, valve body and handwheel 3 is actual is separated, avoids the excessive parts damages such as valve rod 1 grade causing valve body of steering force, safe and reliable.
according to operating mode and the design requirement of valve, the ballast power that stage clip 4 puts on handwheel 3 is adjustable, and then the slipping torque of adjustable gate handwheel 3.Adjustment process is as follows: rotate ballast dish 5, ballast dish 5 opposing projections 21 under the effect of screw thread moves up and down, thus changes the distance between ballast dish 5 and handwheel 3, and the decrement of stage clip 4 changes thereupon, and then reaches the object regulating ballast power.Can according to concrete operating mode and design requirement, the slipping torque of regulating valve handwheel 3, flexible and convenient to use.
rotate at ballast dish 5 in the process regulating ballast power, according to the angle that ballast dish 5 rotates, pointer 6 indicates current ballast power numerical value, and it is convenient to measure, and can realize easily determining torque operation.
by gears meshing between handwheel 3 and transmission, by changing the shape (as adopted Asymmetric V-type groove) of the teeth groove of the first fluted disc 31 and the second fluted disc 22, the ratio of maximum open operation moment and maximum closing operation moment can be changed.
valve handle 3 of the present utility model overallly can replace normal operations handwheel 3 of the prior art, easy to use and flexible.
above-described embodiment is only for illustrating technical conceive of the present utility model and feature; it is a kind of preferred embodiment; its object is to person skilled in the art can understand content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this.All equivalent transformations of doing according to Spirit Essence of the present utility model or modification, all should be encompassed within protection domain of the present utility model.
