Abstract
The utility model relates to a driving device of a valve, which comprises a valve rod, a bracket and a handwheel, wherein the valve rod is connected in a spiral sleeve in a screw mode. The spiral sleeve is sheathed in the bracket, a key hole is arranged in the wall of the spiral sleeve and the top end of the spiral sleeve is provided with a lug boss. The valve rod is provided with a limited post and a key groove corresponding to the key hole. The limited post is matched with the lug boss, guide keys are arranged in the key hole and the key groove, the upper side of the inner wall of the bracket is provided with a guide blind groove, and the lower side of the inner wall of the bracket is provided with an L-shaped through hole groove. A cylindrical pin is fixedly connected with a connecting rod and is linked with the spiral sleeve. The L-shaped through hole groove is matched with the cylindrical pin. The utility model has the advantages of flexible opening and closing and accurate and stable positioning.
Description
The utility model relates to a kind of valve actuator.
Known valve actuator all is made of parts such as handwheel, valve rod and supports, and handwheel drives the valve rod rotation, makes the Sealing action that is connected with valve rod, reaches the purpose of unlatching or throttle down.This valve actuator owing to there is not the accurate in locating device, makes the position after the Sealing action often can not be accurately corresponding with the medium channel on the valve body, therefore very easily causes phenomenons such as dielectric leakage, flow minimizing, sealing part abrasion be fast.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby provides a kind of simple in structure, accurate positioning, open and close valve actuator flexibly.
The utility model comprises valve rod, support and handwheel, and valve rod is screwed onto in the rotation set, and rotation set is sleeved in the support, the rotation set wall is provided with keyhole, the top is provided with boss, and valve rod is provided with limited post and reaches and the corresponding keyway of keyhole, and limited post matches with boss, in keyhole and the keyway feather key is set, the rack inner wall upside is provided with the blind groove of guiding, and downside is provided with L shaped through-hole groove, and straight pin and connecting rod are affixed, and with rotation set interlock, L shaped through-hole groove and straight pin match.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the utility model when being applied to the ball valve opener;
Fig. 2 is the structural representation of the utility model when being applied to ball valve and closing;
Fig. 3 is that the K of Fig. 1 is to view;
Fig. 4 is that the K of Fig. 2 is to view;
Fig. 5 is the assembly relation schematic representation of keyhole and keyway.
As shown in the figure, the utility model comprises that valve rod 1, support 2 and handwheel 3, valve rod 1 are screwed onto in the rotation set 4, rotation set 4 is sleeved in the support 2, the rotation set wall is provided with keyhole 5, the top is provided with boss 6, valve rod 1 is provided with limited post 7 and reaches and keyhole 5 corresponding keyways 8, limited post 7 matches with boss 6, in keyhole 5 and the keyway 8 feather key 9 is set, support 2 inwall upsides are provided with the blind groove 10 of guiding, and downside is provided with L shaped through-hole groove 11, and straight pin 12 is affixed with connecting rod 13, and with rotation set 4 interlock, L shaped through-hole groove 11 and straight pin 12 match.During throttle down, handwheel 3 turns clockwise, valve rod 1 rotation is not risen, simultaneously, the keyway 8 that feather key 9 breaks away from the valve rod 1 enters in the blind groove 10 of guiding of support 2, and rotation set 4 drive straight pins 12 revolve in L shaped through-hole groove 11 and turn 90 degrees, make and sealing surface in connecting rod 13 attached seal are just in time aimed at valve body 14, be rotated further handwheel, garden pin 12 runs to L shaped through-hole groove 11 bottoms, Sealing and sealing surface contact, valve closing.Otherwise when being rotated counterclockwise handwheel 3, rotation set 4 rises, and straight pin 12 runs to L shaped through-hole groove 11 tops, Sealing and sealing surface are separated, and feather key 9 enters in the keyway 8 simultaneously, and limited post 7 is stuck on the boss 6, valve rod 1 and rotation set 4 rotate synchronously, make Sealing hole aligned through holes, valve opening.
The utility model has valve opening and closes flexibly the switch accurate positioning by above-mentioned concrete structure Stable advantage is a kind of valve actuator that is worthy of popularization.
