Abstract
The utility model provides a switch lightweight plug valve, through stretch one section extension portion below the cock of plug valve, set up the fine pitch trapezoidal thread in the extension portion, the trapezoidal thread is fixed on the valve body through the cock nut, the reuse locknut fix the cock nut, reuse safety cover in outside covers this structure, when handle and pipeline level, the valve is in closed position, want this moment the regulating cock nut to make the plug valve seat cover can play sealedly, then it is fixed the cock nut with locknut, to start the valve after that, the handle drove the cock rotation this moment, and the following trapezoidal thread of stretching of cock begins the action, drive some distances of cock rebound, just also make cock and disk seat cover break away from, such structure is that the switch of plug valve is just light a lot.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of switch handy type stopcock.
Background technique
In use, because the cock of stopcock and valve seat cover always are close contact, therefore moment of torsion is very large for the stopcock of existing routine, thus it is all very hard to cause stopcock to open and close, and makes its in use unusual inconvenience.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of switch handy type stopcock.
The technical solution that the utility model adopts is: a kind of switch handy type stopcock, comprise valve body, valve gap, valve rod, valve seat, handle and cock, described valve seat is provided with valve seat cover, described valve body and valve gap are installed by bolt and are connected, extending part is extended with bottom described cock, be provided with trapezoidal thread outside described extending part, be provided with fastener assembly outside described extending part, described extending part is fixed on valve body by fastener assembly.
Also be provided with safety cover outside described extending part and fastener assembly, described safety cover is fixedly mounted on valve body.
Described fastener assembly comprises cock nut and lock nut, and described extending part is fixed on valve body by cock nut, and described lock nut is arranged on outside cock nut.
Also be provided with filler between described valve rod and valve gap, described filler is also provided with follower, described follower is provided with gland, and described gland is bolted to connection on valve gap.
The beneficial effects of the utility model are: the utility model provides a kind of switch handy type stopcock, by stretching one section of extending part below the cock of stopcock, extending part is arranged fine pitch trapezoidal thread, trapezoidal thread is fixed on valve body by cock nut, with a lock nut, cock nut is fixed again, outside covers this structure with a safety cover again, when handle and pipe level, valve is in the closed position, regulating cock nut is now wanted to make stopcock cover for seat play sealing, then with lock nut, cock nut is fixed, then actuating valve is wanted, now handle drives cock to rotate, and the trapezoidal thread stretched below cock starts action, cock is driven to move up some distances, also cock and valve seat cover is just made to depart from, such structure is that the switch of stopcock is just much light.
