Along with the development of industrial refrigeration, the raising of safety requirement, industrial refrigeration valve automaticity requires more and more higher, check valve structure common at present has rotary-open type and rise-fall type etc., because these products exist easily sticky card, poorly sealed, cause safety check not close flexibly, equipment safety operation is difficult to ensure, will cause unnecessary loss.
Model utility content
The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of flow resistance little, open and close flexibly, good seal performance, the industrial refrigeration safety check of long service life.
The utility model solves the technological scheme that its technical problem adopts: a kind of industrial refrigeration safety check, comprise valve seat, valve gap, flap, flap pad, pressing plate, spring, beam, flange gasket, flange screw, described valve seat is provided with inlet tube, outer pipe, valve seat flange and sealing surface of seat, described valve gap is provided with buffer cell and bonnet flange, beam is provided with in buffer cell, described valve seat and valve gap are locked by flange screw, flange gasket seal is used in centre, flap pad and rag iron spring is provided with bottom described flap, by medium in valve and spring, flap is moved up and down in buffer cell, make valve open or closedown.
Further, described valve seat is right-angle type valve seat, and its inlet tube and outer pipe median perpendicular, the center line of its sealing surface of seat becomes 90 with the center line of outer pipe °angle.
Further, described valve seat is straight-through type valve seat, and its inlet tube overlaps with outer pipe center line, and the center line of its sealing surface of seat becomes 45 with the center line of outer pipe °angle.
Further, described valve seat flange and bonnet flange are round flange or square flange.
The beneficial effects of the utility model are: the utility model safety check is applied in industrial refrigeration field, and reduce manual operation, Safety performance is improved significantly, and this valve flow resistance is little, and open and close flexibly, good seal performance, long service life, is more and more applied.
