Description
Technical field
The utility model relates to a kind of stop valve, particularly a kind of direct insertion Angle Stop valves.
Background technique
Angle Stop valves open-shut device is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of fluid.The forms of motion of valve rod, has elevating lever-type (valve rod is elevated, and handwheel is not elevated), also has lifting rotation rod-type (handwheel is rotation and lifting together with valve rod, and nut is located on valve body).Line pipe stop valve is only applicable to standard-sized sheet and complete shut-down, does not allow to make adjustments and throttling.
But this kind of stop valve all needs rotation valve rod in opening-closing process, between valve rod and Sealing, long spin friction exacerbates the loss of Sealing, easily leaks, cannot ensure use safety.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of direct insertion Angle Stop valves, and structure is simple, and open-close convenient, without the need to rotation valve rod, farthest decreases the loss of Sealing, add working life, ensure that use safety.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of direct insertion Angle Stop valves, comprise valve body, valve rod, spool and valve gap, valve stem passage is provided with in described valve body, inlet passage and outlet passage, described valve stem passage, inlet passage and outlet passage are all fixed by valve gap, fixing cutting ferrule is provided with in described valve stem passage, main spring is provided with in the first cavity that described fixing cutting ferrule bottom and valve stem passage bottom are formed, described valve rod is fixed in valve stem passage through fixing cutting ferrule, described valve rod comprises valve rod main body and clamping part, described valve rod main body is cylindrical structural, described clamping part comprises head rod and clamping joint, described head rod is cylindrical structural, clamping joint is hemispherical dome structure, described clamping part center is provided with the groove of " ten " font, clamping part is evenly divided into four points, described spool is fixed on valve rod main body bottom by the second connecting rod, the length L1 of described second connecting rod is greater than the length L2 of described clamping part, described valve stem passage wall updip is tiltedly provided with four push rod passages, the outlet of described lower one end of push rod passage is positioned at below fixing cutting ferrule, slidably push rod is provided with in described push rod passage, described push rod is circumferentially with a circle baffle plate, the second spring is sheathed with outside push rod, described second spring one end is fixed in push rod passage, the other end contacts with the baffle plate on push rod.
The direct insertion Angle Stop valves of above-mentioned one, wherein, described valve rod is sheathed with the first stuffing box packing from top to bottom successively, seal ring and the second stuffing box packing.
The direct insertion Angle Stop valves of above-mentioned one, wherein, the diameter D1 of described clamping joint is greater than the diameter D2 of head rod.
The beneficial effects of the utility model are:
Valve rod of the present utility model comprises valve rod main body and clamping part, the uniqueness of clamping part arranges and makes it for fixing cutting ferrule, define self-locking structure, when needing to close stop valve, only need to press valve rod downwards, make clamping part slip over fixing cutting ferrule can be locked, make spool block input port passage, play closing function, meanwhile, the first spring is in compressive state due to clamping part effect, when needs opening stop valve, press four push rods simultaneously, the outlet of the lower one end of push rod passage residing for push rod is positioned at below fixing cutting ferrule, when namely pressing lower push-rod, push rod one end extruding clamping joint inwardly compresses, valve rod slips over fixing cutting ferrule and moves up to original position under the elastic force effect of the first spring, now spool leaves inlet passage, stop valve is opened, and push rod is being returned to original position by under the effect of the second spring compressed, structure is simple, open-close convenient, good airproof performance, and whole process is without the need to rotation valve rod, farthest decrease the loss of Sealing, add working life, ensure that use safety.
