Abstract
A swing check valve comprises a valve body, a valve base, a valve cover and a valve clack. The swing check valve is characterized in that the dish-cover type valve clack is arranged on the valve base; a hinge rod is arranged outside of the valve clack; the upper end of the hinge rod is hinged on the valve body by a hinge shaft; and the valve clack is arranged on the valve body. The utility model solves the problem that a common valve is manually opened and closed and is suitable for controlling the flow flux.
Description
Technical field:
The utility model relates to the flow control field of fluid line, specifically a kind of flow control valve of liquid.
Background technique:
The valve that uses is gone up by society at present, and its keying form all is to operate manually, and its shortcoming is can not automatic on-off.
Summary of the invention:
The utility model is invented a kind of valve that flows by flap rotation control media for solving common valve keying form by manually-operated problem.
The technical solution of the utility model is that a kind of Swing check valve comprises valve body, valve seat, valve gap, flap, 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.The medium import is left on the flap right side.
When MEDIA FLOW is fashionable, the pushing that flap is subjected to medium is outwards moved, and promotes toggle and rotates around hinge, with valve open; When medium stopped to flow into, the backpressure of medium promoted in flap was managed, drove toggle and rotated return around hinge, valve closing was stoped the refluence of medium.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize a kind of automatic on-off control media refluence metered valve door.
Description of drawings
Fig. 1 is the structural front view of model utility, and the accompanying drawing that makes an abstract.
In the drawings, 1 valve body, 2 valve seats, 3 flaps, 4 toggles, 5 hinges, 6 medium imports.
Embodiment
Below in conjunction with accompanying drawing embodiment, further specify this enforcement is novel.
As shown in FIG., disk cover shape flap 3 is housed on valve seat 2, 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, and flap 3 is contained on the valve body 1.Medium import 6 is left on flap 3 right sides.
When MEDIA FLOW is fashionable, the pushing that flap 3 is subjected to medium is outwards moved, and promotes toggle 4 and rotates around hinge 5, with valve open; When medium stopped to flow into, the backpressure of flap 3 managed interior media promoted, and drove toggle 4 and rotated returns around hinge 5, valve closing was stoped the refluence of medium.
