Abstract
A flange lifting check valve comprises a valve body, a valve seat, a valve clack, a flange and a valve deck. The flange lifting check valve is characterized in that the valve body is connected with a pipeline through the flange. Problems of being not easy to detach, to maintain and to replace in existing check valves are resolved. The flange lifting check valve is suitable for controlling liquid flow or gas flow.
Description
Technical field:
The utility model relates to the flow control field of fluid line, specifically a kind of flow control valve of adjutage duct device liquid.
Background technique:
Its connection pattern of the valve of design production is that weld seam connects on the present society, and its shortcoming is that long-term the use is not easy to dismantle and keeps in repair and change, and wasteness is large.
Summary of the invention:
The utility model is invented a kind of flange lift check valve for solving the long-term problem dismantling, keep in repair and change of being not easy to of using of common valve, it is characterized in that valve body and the Placement of pipeline are that flange is connected.
The technical solution of the utility model is, a kind of flange lift check valve is made of valve body, flap, flange, valve gap, outside it is special is, valve connects and adopts flange to connect, and convenient disassembly is convenient to maintenance and is changed.
Flange is processed by boring and surface Machining, adopts bolt and flange that valve is connected on the pipeline.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize that a kind of valve adopts flange to connect, and convenient disassembly is convenient to maintenance and is changed.
Description of drawings
Fig. 1 is the structural front view of model utility, and the accompanying drawing that makes an abstract.
In the drawings, valve body 1, valve seat 2, flap 3, flange 4, valve gap 5.
Embodiment
Below in conjunction with accompanying drawing embodiment, further specify this enforcement is novel.
As shown in FIG., vertical column flap 3 is housed in valve body 1, the lower end of flap 3 places on the valve seat 2, horizontal media outlet is left at the middle part of flap 3, leaves the medium import below the valve seat 2, and the lower end of flap 3 becomes the conehead shape, valve body 1 two ends are with flange 4, and valve body 1 is connected with valve gap 5 bolts.
During maintenance, dismounting flange 4 bolts can take out valve.
Can realize that a kind of valve flanges is connected with pipeline, use for a long time convenient disassembly, be convenient to maintenance and replacing.
