Abstract
The utility model relates to a flange stop valve, which comprises a valve body, flanges, a valve cover, a valve rod and a valve clack, and is characterized in that the flanges are assembled at the connectors of the two ends of the valve body and a pipeline, through holes for mounting bolts are formed on the flanges, and the flanges are utilized for connecting with a pipeline device during mounting. By adopting the flange stop valve, the problems that the connection way for the stop valve which is currently designed and produced and the pipeline adopts welding connection, and the stop valve is inconvenient to detach, maintain and replace after long-term use can be solved, and the flange stop valve is applicable to the pipeline flow control field in petroleum, chemical engineering, oil refining, metallurgy and the like.
Description
Technical field
The utility model relates to the flow control field of fluid line, the control valve of specifically a kind of pipeline liquid, gas flow.
Background technique
At present, in the pipeline fluid control field of industries such as oil, chemical industry, oil refining, metallurgy, generally its Connecting format of the stop valve of Shi Yonging all is welded to connect, and its shortcoming is to be not easy to dismounting, to keep in repair and to change after long-term the use, disposable use, and waste is big.
Summary of the invention
The utility model is invented a kind of employing flange flange connecting stop valve for solving the long-term problem of dismantling, keeping in repair and changing of being not easy to of using of common valve.
The technical solution of the utility model is, a kind of Flange Globe Valves comprises valve body, flange, valve gap, valve rod, flap, and its special way is, valve body two ends and pipeline connection port place are equipped with flange respectively, have the through hole that construction bolt is used on the flange, valve body and valve gap bolted on connection, valve rod is equipped with at the valve gap middle part, stem lower portion is connected with flap, valve body and flap are sealed and matched, and Stem Mut is equipped with on valve rod top, Stem Mut be peripherally equipped with handwheel.
During installation, with flange valve body is connected with tube equipment with bolt.During the flow of controlling plumbing fixtures, rotate handwheel, handwheel drives flap by valve rod and rotates, thereby changes the flow of pipeline.During maintenance, unclamp the bolt of adpting flange and pipeline, valve is taken off.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize that a kind of employing flange connects, and is convenient to the dismounting maintenance and changes the stop valve of controlling plumbing fixtures fluid flow.
Description of drawings
Fig. 1 is a structural front view of the present utility model, and the accompanying drawing that makes an abstract.
Through hole in the drawings, 1, valve body, 2, flange, 3, valve gap, 4, valve rod, 5, flap, 6, Stem Mut, 7, handwheel, 8.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further specified.
As shown in Figure 1, valve body 1 two ends and pipeline connection port place are equipped with flange 2 respectively, have the through hole 8 that construction bolt is used on the flange 2, valve body 1 is used bolted on connection with valve gap 3, valve rod 4 is equipped with at valve gap 3 middle parts, and valve rod 4 bottoms are connected with flap 5, and valve body 1 is sealed and matched with flap 5, Stem Mut 6 is equipped with on valve rod 4 tops, Stem Mut 6 be peripherally equipped with handwheel 7.
During installation, valve is connected on the tube equipment with bolt and flange 2.During the flow of controlling plumbing fixtures, rotate handwheel 7, handwheel 7 drives flaps 5 by valve rod 4 and rotates, thereby changes the flow of pipeline.During maintenance, unclamp the bolt of adpting flange 2 and pipeline, valve is taken off.
