Abstract
The invention discloses a flange swing check valve which comprises a valve body, a valve seat, a valve clack and a valve cap and has the characteristics that a plate cover shaped valve clack is arranged on the valve seat; a hinge bar is arranged outside the valve clack; the upper end of the hinge bar is connected on the valve body through a hinge shaft; the valve clack is arranged on the valve body. The flange swing check valve solves the problems that the existing swing check valves are inconvenient to assemble, disassemble and repair. The flange swing check valve is applied for the flow control of liquid and gas.
Description
Technical field:
The present invention relates to the flow control field of fluid line, specifically a kind of control valve of adjutage duct device fluid flow.
Background technique:
Social at present its Connecting format weld seam of Swing check valve that designs production of going up connects, and its shortcoming is to use for a long time to be not easy to dismantle and to keep in repair and change.
Summary of the invention:
The present invention invents the valve that a kind of flange connects for solving the long-term problem of dismantling and keeping in repair and changing of being not easy to of using of common valve.
Technological scheme of the present invention is that a kind of flange Swing check valve comprises valve body, valve seat, flap, valve gap; Outside it is special be, disk cover shape flap is housed on valve seat, on the outside of flap toggle is housed; The upper end of toggle is connected on the valve body by hinge, and flap is contained on the valve body.
Technique effect of the present invention is, adopts above-mentioned technological scheme, can realize a kind of valve of automatic on-off control media refluence amount.
Description of drawings
Fig. 1 is the structural front view of invention, and the accompanying drawing that makes an abstract.
In the drawings, 1 valve body, 2 valve seats, 3 flaps, 4 toggles, 5 hinges, 6 valve gaps.
Embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is further specified.
Shown in figure, on the valve seat 2 disk cover shape flap 3 is housed in the valve body 1, toggle 4 is housed on the outside of flap 3, the upper end of toggle 4 is connected on the valve body 1 by hinge 5.
Can realize that a kind of long-term use is not easy to produce the liquid of leakage phenomenon, gas flow control valve.
