Abstract
The utility model discloses a valve rod, valve rod include the screw thread section and the valve rod head at polished rod section and polished rod section both ends, and open on the top of valve rod head has the spread groove, are close to valve rod head department in the polished rod section and are equipped with the bellows, and one end far away apart from the valve rod head on the bellows is fixed with the safety cover. The utility model has the characteristics of simple structure, ingenious effectively strengthens valve rod intensity, improves the valve rod leakproofness.
Description
Technical field
This utility model relates to a kind of valve rod.
Background technology
Valve rod is the vitals in valve arrangement, for transmission, above connects actuator or handle, and band movable valve plug moves or rotates directly below, to realize switch or the regulation effect of valve.During use, once valve stem seal is destroyed, and deep-etching, volatile and poisonous and hazardous processing medium leak out from control valve valve rod, surrounding enviroment and personal safety can be brought serious consequence.
Summary of the invention
The purpose of this utility model is to overcome above deficiency, it is provided that a kind of simple in construction, ingenious, effectively strengthens valve rod intensity, improves the valve rod of valve stem seal.
The purpose of this utility model is achieved through the following technical solutions: a kind of valve rod; valve rod includes light bar segment and the thread segment at light bar segment two ends and valve rod head; the top of valve rod head has link slot; being provided with corrugated tube at valve rod head in light bar segment, on corrugated tube, distance valve rod head one end farther out is fixed with protective cover.
Further improvement of the utility model is: have escape between thread segment and light bar segment.
Further improvement of the utility model is: protective cover is bowl structure.
Further improvement of the utility model is: light bar segment, thread segment and valve rod head are in coaxially.
Further improvement of the utility model is: the degree of accuracy of light bar segment reaches mirror effect.
This utility model compared with prior art has the advantage that
This utility model simple in construction, ingenious; efficiently solve once valve stem seal to be destroyed; the problem that deep-etching, volatile and poisonous and hazardous processing medium leak out from control valve valve rod; the stuffing-box of corrugated tube protection control valve is avoided contacting with fluid; meanwhile, after the protective cover that corrugated tube is provided with is prevented effectively from bellows bursts, stuffing-box contacts with fluid；Have escape between thread segment and light bar segment, facilitate the machining of thread segment；Light bar segment, thread segment and valve rod head are in coaxially, convenient overall processing；The degree of accuracy of light bar segment reaches mirror effect, opens and closes easily, good airproof performance.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model；
Label in figure: 1-light bar segment, 2-thread segment, 3-escape, 4-protective cover, 5-valve rod head, 6-corrugated tube.
Detailed description of the invention:
In order to deepen understanding of the present utility model, below in conjunction with example and accompanying drawing, the utility model is described in further detail, and this embodiment is only used for explaining this utility model, is not intended that the restriction to this utility model protection domain.
As Fig. 1 shows a kind of embodiment of this utility model valve rod; valve rod includes light bar segment 1 and the thread segment 2 at light bar segment 1 two ends and valve rod head 5; the top of valve rod head 5 has link slot 7; at valve rod head 5, it is provided with corrugated tube 6 in light bar segment 1; on corrugated tube 6, distance valve rod head 5 one end farther out is fixed with protective cover 4; escape 3 is had between thread segment 2 and light bar segment 1; protective cover 4 is bowl structure; light bar segment 1, thread segment 2 and valve rod head 5 are in coaxially, and the degree of accuracy of light bar segment 1 reaches mirror effect.
This utility model simple in construction, ingenious; efficiently solve once valve stem seal to be destroyed; the problem that deep-etching, volatile and poisonous and hazardous processing medium leak out from control valve valve rod; corrugated tube 6 is protected the stuffing-box of control valve to avoid with fluid and is contacted; meanwhile, the protective cover 4 that corrugated tube 6 is provided with is prevented effectively from corrugated tube 6 and ruptures rear stuffing-box and contact with fluid；Have escape 3 between thread segment 2 and light bar segment 1, facilitate the machining of thread segment 2；Light bar segment 1, thread segment 2 and valve rod head 5 are in coaxially, convenient overall processing；The degree of accuracy of light bar segment 1 reaches mirror effect, opens and closes easily, good airproof performance.
The foregoing is only explanation embodiment of the present utility model; it is not limited to this utility model; for a person skilled in the art; all within spirit of the present utility model and principle; the any modification, equivalent substitution and improvement etc. made, within should be included in protection domain of the present utility model.
