Embodiment
Referring to accompanying drawing, a kind of rotary valve lockset of the utility model comprises the housing of patty, and housing is by constituting through rotating shaft 3 hinged first housing 1 and second housings 2, and first housing 1 and second housing 2 are the semicircle cheese of symmetry.When first housing 1 and second housing 2 had the corresponding and lug 5 that have a through hole in position and close up with lug 4, the first housings 1 and second housing 2, lockset capable of using locked lug 5 and lug 4, prevented that housing from opening.
Be provided with support and valve rod locking mechanism in the housing, housing also has bottom opening and is used to penetrate valve rod.
Support is a cylindrical shape, and 8 two-part are stacked forms by last ring 9 and ring down, on encircle 9 with ring 8 two-part intersections down be circular groove.
In order to reduce surface friction drag; Be provided with the annular cover in the circular groove of support excircle; Annular cover by last cover 12 with trap that 11 two-part are stacked to form, on overlap 12 with 11 the intersection of trapping be second circular groove, inner walls is provided with the annular flange flange 7 that embeds this second circular groove; Through cooperating of circular groove and annular flange flange 7, can realize being rotatably assorted of support and housing.Because first housing 1 and second housing 2 need open sometimes, so annular flange flange 7 is between part and second circular groove of first housing, 1 inwall and is adhesively fixed, and can guarantee that like this second housing 2 freely opens, and first housing 1 can not come off.Drive the annular cover when housing rotates and rotate, can reduce surface friction drag with the support outer wall.
The valve rod locking mechanism comprises the housing 6 that is fixed on down ring 8 bottom surfaces, and with the puller bolt 14 of housing 6 screw-thread fit.Support go up ring 9, down encircle 8 and this housing 6 connect fixing through bolt 10.
The position, termination of puller bolt 14 is equipped with the chuck 13 that is rotatably assorted, and chuck 13 is respectively equipped with the sunk area 17 and sunk area 16 that shape matches with the valve rod outer wall with housing 6 inboards, is convenient to lock valve rod.
The position, termination of puller bolt 14 has annular groove, and 13 chucks have mounting groove, and the inwall of mounting groove is provided with the pin 15 that stretches into annular groove.Chuck 13 still can rotate puller bolt 14 after holding valve rod tightly with housing 6 inboards, further locks or loosens valve rod, because puller bolt 14 is rotatably assorted with chuck 13, so the rotation of locking screw 14 does not influence chuck 13.
Can take off valve handle or handwheel earlier during use, valve stem tip is exposed, utilize the valve rod locking mechanism to clamp valve rod again; Because housing is with support and valve rod locking mechanism parcel, when therefore misoperation occurring, stressed member is to be in outside housing; But housing and support are rotatably assorted, so support and valve rod locking mechanism do not rotate during the stressed rotation of housing, and promptly valve rod does not rotate; Keep original state, not only eliminated potential safety hazard, and avoid damaging pipeline.
