Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and the best embodiment. Based on the embodiments in the utility model, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the utility model.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

As shown in fig. 1-3, a marine double sealing wave-proof valve, including casing 4, the internally mounted of casing 4 has valve body 7, the both ends of valve body 7 are equipped with water inlet 6 and delivery port 9 respectively, the inside of delivery port 9 is equipped with prevents adverse current passageway 8, and the edge of preventing adverse current passageway 8 is the arc, the inside of valve body 7 is equipped with movable rod 1, and movable rod 1 and the inside swing joint of valve body 7, the bottom of movable rod 1 is equipped with limiting plate 16, and the equipment is T type structure between limiting plate 16 and the movable rod 1, lifter plate 17 is installed to the top surface of limiting plate 16.

The adoption prevents passageway 8 against current, the both ends of valve body 7 are water inlet 6 and delivery port 9 respectively, water inlet 6 is normal pipeline, what increase in the pipeline of delivery port 9 prevents the structure against current, the effect of preventing the structure against current is that the fluid normally passes through valve body 7 control, through water inlet 6 to delivery port 9 normal flow, because can go out to have when stormy waves is great, outboard water has in some backward flow pipelines, self-closing function to ordinary valve body 7 can not be complete seals, consequently at the in-process of backward flow through delivery port 9, the department of bending of preventing inside passageway 8 against current can produce striking and resistance to the fluid of backward flow, thereby can not produce too big fluid dynamics to the fluid of backward flow, thereby can realize valve body 7's normal use, the effect of cooperation valve body 7 itself, guarantee that it is sealed.

The anti-reverse flow channel 8 is a passive one-way channel with a fixed geometric shape, can enable fluid to flow in one direction, and has a fixed geometric shape, so that the defect that a traditional valve is easy to damage due to the fact that a movable part is needed is overcome.

Control head 2 is installed at the top of movable rod 1, and movable rod 1 inlays in control head 2's inside, and the bottom surface edge of movable rod 1 is equipped with solid fixed ring 3, and the surface connection of solid fixed ring 3's bottom and casing 4, and the internally mounted of valve body 7 has top spring 10, and the bottom of top spring 10 is equipped with movable block 11, and movable block 11 and 4 inner wall swing joint of casing.

Valve body 7 internally mounted has support body 14, and the inside of support body 14 is equipped with end cap 12, and end cap 12 and the inside swing joint of support body 14, is equipped with spacing head 13 between end cap 12 and the limiting plate 16, and spacing head 13 inlays in the inside of end cap 12, and spacing head 13 and end cap 12 are T type structure, and the edge of lifter plate 17 is equipped with rubber membrane 5, and the edge connection casing 4's of rubber membrane 5 inner wall, and mount 15 is installed at the top of support body 14.

When a small amount of fluid flows backward to valve body 7 inside, can produce certain power, can extrude lifter plate 17, the in-process of the rising of lifter plate 17 can drive the rising of limiting plate 16, blocks up the passageway at casing 4 top until lifter plate 17, and movable rod 1 can drive holistic valve member and rise the removal in step, and the fluid also can normally flow to can not produce the condition of revealing.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
