Abstract
The invention discloses a flange cutoff valve, which comprises a valve body, flanges, a valve cover, a valve rod and a valve clack, and is characterized in that: two ends of the valve body and a pipeline connecting port are provided with a flange respectively; through holes for mounting bolts are formed in the flanges; and the flanges are connected with a pipeline device during installation. The problems that the cutoff valve which is designed and produced in society at present is inconvenient to dismount, maintain and replace after being used for a long time due to the welding connection mode between the cutoff valve and the pipeline are solved, and the flange cutoff valve is applied in the fields of petroleum, chemical industries, oil refining, metallurgy and the like for pipeline flow control.
Description
Technical field
The present invention 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 present invention invents 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.
Technological scheme of the present invention 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 invention 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 invention, 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 present invention is further described.
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.
