Abstract
The utility model discloses a straight-through stop throttle, mainly comprising a valve body (3), a valve rod, a handle (12), a valve body pipe (2) and a flange (1). The valve rod is installed inside the valve body (3); the handle (12) is installed on the upper end of the valve rod; the valve body pipe (2) is connected to both sides of the valve body (3); the utility model is characterized in that the flange (1) is movably installed on the valve body pipe (3). The valve is forged combined type, adopting parallel straight type instead of angle type structure and spheral sealing on movable conical surface of crewed flange instead of casting entirety type planar sealing of left and right flanges; it features in convenient installation, good sealing effect and wide adaptability and absence of restriction of tooling.
Description
Affiliated technical field
The utility model relates to valve, is specifically related to novel straight-through type cut-off throttle valve.
Background technique
In industries such as oil, chemical industry, chemical fertilizer, nuclear power, medicine, stop valve or safety check are applied to rise on the various workshop sections pipeline of media such as High Temperature High Pressure deep-etching and block throttling action, present stop valve or safety check are cast inblock angie type structure, inconvenience is installed on the one hand, and sealing effect is poor on the other hand.
Summary of the invention
The purpose of this utility model is: a kind of novel straight-through type cut-off throttle valve is provided, and is parallel bypass structure by the angie type structural design, and convenient on the one hand the installation improved sealing effect on the other hand.
Technical solution of the present utility model is: this valve mainly is made up of valve body, valve rod, handle, valve body tube, flange, valve rod is installed in the valve body, handle is installed in the valve rod upper end, and valve body tube is connected the valve body both sides, it is characterized in that: flange is movable to be installed on the valve body tube.
Valve rod of the present utility model connects lower valve rod by upper valve rod through coupling and forms, and coupling comprises shaft coupling collar, shaft coupling cutting ferrule, check ring, and the shaft coupling collar is wrapped in the junction of lower valve rod, and shaft coupling cutting ferrule and check ring be the shaft coupling collar fixedly.
On the valve body of the present utility model Stuffing box is installed, filler is positioned at Stuffing box, and Stuffing box is installed on the valve body through connecting bolt, establishes gland on the Stuffing box, and gland is installed on the vavle shelf by regulating bolt through pressure strip, establishes O type circle on the Stuffing box.
The stock connecting bolt is installed between the utility model valve body and vavle shelf.
The utlity model has following advantage: 1. this valve is that forging is combined, by the angie type structural design is the straight parallel general formula, left and right sides flange is changed into the movable conical surface of screwed flange in ball face sealing by casting integrated plane sealing, easy for installation, quick, good sealing effect, the wide adaptability model is not limited by frock; 2. Stuffing box connects with valve body, and the conical surface and ball face sealing are adopted in its sealing, and other adds two road O type circle selfsealings, the phenomenon thereby the minimizing medium leaks outside, and sealability is reliable and stable; 3. valve rod adopts fraction structure up and down, makes the upper valve rod rotation by coupling, and lower valve rod advances lifting, rotates the wearing and tearing that bring to filler thereby change former valve rod integrated type, has strengthened the sealing effect and the life cycle of filler.
