Abstract
The invention discloses a carbon steel flange gate valve which comprises a valve body, a gate plate, flanges, a valve cover, a valve rod, a valve rod nut and a hand wheel. The carbon steel flange gate valve is characterized in that the flanges are respectively arranged at two ends of the valve body and a pipeline connection orifice; through holes used for mounting bolts are formed in the flanges; the valve body is connected with the valve cover by virtue of the bolts; the valve rod is mounted in the middle of the valve cover; the lower part of the valve rod is connected with the valve flap; the valve body is in sealing fit with the valve flap; a valve rod nut is mounted at the upper part of the valve rod; a hand wheel is mounted at the periphery of the valve rod nut. When the carbon steel flange stop valve is mounted, the valve is connected to a pipeline device by virtue of the bolts and the flanges. When the flow of the pipeline is controlled, the hand wheel is rotated and is used for driving the gate plate to move by virtue of the valve rod, so that the flow of the pipeline is changed; when the carbon steel flange gate valve is maintained, the bolts used for connecting the flanges with the pipeline are loosened, and the valve is taken down.
Description
Technical field
The present invention relates to the flow control field of fluid line, specifically the control valve of a kind of liquid, gas flow.
Background technique
At present, its Connecting format of gate valve for pipeline flow control fields such as oil, chemical industry, oil refining, metallurgy is all welded to connect, and its shortcoming is not easy to dismounting, maintenance after Long-Time Service and changes, single use, and waste is large.
Summary of the invention
The present invention is the problem that solution common valve Long-Time Service is not easy to dismantle, keep in repair and change, and invents a kind of simple steel flange gate valve adopting Flange joint.
Technological scheme of the present invention is, a kind of simple steel flange gate valve, comprise valve body, flashboard, flange, valve gap, valve rod, Stem Mut, handwheel, its special way is, valve body two ends and pipeline connection port place are respectively fitted with flange, flange has the through hole of construction bolt, valve body is connected with valve cover bolt, in the middle part of valve gap, valve rod is housed, stem lower portion is connected with flashboard, valve body coordinates with ram seal, and Stem Mut is equipped with on valve rod top, Stem Mut be peripherally equipped with handwheel.
During installation, with bolt and flange, valve is connected on tube equipment.When controlling the flow of pipeline, rotate handwheel, handwheel drives flashboard to move by valve rod, thus 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 a kind of employing Flange joint, be convenient to detachable maintaining and replacing, control the gate valve of pipeline fluid flow.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
In the drawings, 1, valve body, 2, flashboard, 3, flange, 4, valve gap, 5, valve rod, 6, Stem Mut, 7, handwheel, 8, through hole.
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 respectively fitted with flange 3, flange 3 has the through hole 8 of construction bolt, valve body 1 is connected with bolt with valve gap 4, valve rod 5 is housed in the middle part of valve gap 4, and valve rod 5 bottom is connected with flashboard 2, and valve body 1 and flashboard 2 are sealed and matched, Stem Mut 6 is equipped with on valve rod 5 top, Stem Mut 6 be peripherally equipped with handwheel 7.
During installation, with bolt and flange 3, valve is connected on tube equipment.When controlling the flow of pipeline, rotate handwheel 7, handwheel 7 drives flashboard 2 to move up and down by valve rod 5, thus changes the flow of pipeline.During maintenance, unclamp adpting flange 3 and the bolt of pipeline, valve is taken off.
Claims (1)
