Abstract
A kind of reducing check valve, by setting up rubber seal between flap and valve seat, the grommet between the upper end of proportioning valve intracoelomic cavity and valve pocket, adopts rubber seal and this multiple sealing means of grommet to make reducing check valve inside reach excellent sealing effect.
Description
Technical field
The utility model relates to valve field, is specifically related to a kind of reducing check valve.
Background technique
Safety check is also known as one-way valve or check valve, and its effect prevents the medium in pipeline from flowing backwards.The bottom valve that pump sump closes also belongs to safety check class.Forged steel safety check has two kinds of body lids to connect design form: the first is that body bonnet bolt connects forged steel safety check, the valve designed by this Connecting format, and its valve body is connected with valve cover bolt, and spiral wound gasket seals, and advantage is convenient to maintenance; The second body lid welds sealing forged steel safety check entirely, and the valve designed by this Connecting format, its valve body is connected with spiral shell mosquito with valve gap, entirely welds sealing, and advantage is No leakage.Forged steel safety check flap form also has the type that dams, needle-like, ball-type respectively, can according to actual conditions reasonable selection, and sealing effect between mangetic core assembly in existing reducing check valve is unreliable, causes the problem that valve body working life is short and leak.
Summary of the invention
In order to solve the deficiencies in the prior art, of the present utility modelly provide a kind of reducing check valve.
The technical solution that the utility model adopts is: a kind of reducing check valve, comprise valve body, described valve body includes valve seat, described valve seat is provided with flap, described valve seat and flap are sealed and matched, described flap is connected with valve shaft, outside described valve shaft, is provided with valve pocket, between described flap and valve seat, be provided with rubber seal.
Described flap also includes flap support column, and described flap support column is sheathed between valve shaft and valve pocket.
Upper end and the valve pocket of described body cavity are also provided with grommet, and described grommet and body cavity are slidably matched.
Described rubber seal coordinates with the end face seal of valve seat.
Described rubber seal coordinates with the end face seal of flap.
The end face of described valve seat and the end face of flap are metal hard-sealing face.
Described valve body is also provided with the mounting hole for installing.
The beneficial effects of the utility model are: the utility model provides a kind of reducing check valve, by setting up rubber seal between flap and valve seat, grommet between the upper end of proportioning valve intracoelomic cavity and valve pocket, adopts multiple sealing means to make reducing check valve inside reach excellent sealing effect.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
1-valve body in figure, 2-rubber seal, 11-valve seat, 12-flap, 13-valve shaft, 14-valve pocket, 15-grommet, 16-mounting hole.
Embodiment
Existing composition graphs 1 pair of the utility model is further described, a kind of reducing check valve, comprise valve body 1, described valve body 1 includes valve seat 11, described valve seat 11 is provided with flap 12, and described valve seat 11 is sealed and matched with flap 12, and described flap 12 is connected with valve shaft 13, described flap 12 also includes flap support column 14, and described flap support column 14 is sheathed between valve shaft 13 and valve pocket 14.Be provided with valve pocket 14 outside described valve shaft 13, between described flap 12 and valve seat 11, be provided with rubber seal 2.Upper end and the valve pocket 14 of described valve body 1 inner chamber are also provided with grommet 15, and described grommet 15 is slidably matched with valve body 1 inner chamber.By setting up rubber seal 2 between flap 12 and valve seat 11, coordinating the grommet between the upper end of valve body 1 inner chamber and valve pocket 14, adopting multiple sealing means to make reducing check valve inside reach excellent sealing effect.。
Described rubber seal 2 coordinates with the end face seal of valve seat 11, and described rubber seal 2 coordinates with the end face seal of flap 12.The end face of described valve seat 11 and the end face of flap 12 are metal hard-sealing face.
Described valve body 1 is also provided with the mounting hole 16 for installing.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
