Description
Technical field
The utility model relates to valve technology field, particularly a kind of for ducted air inlet and exhaust valve.
Background technique
Air inlet and exhaust valve is a kind of large and small port that simultaneously possesses, and when pipeline blank pipe water-filling, realizes Quick air-discharge, air inlet fast again while producing negative pressure in pipeline, and the intake and exhaust device of the micro-air of assembling in can discharge conduit under working pressure.Air inlet and exhaust valve has the function of automatic water seal after draining gas.The valve gap that the structure of existing air inlet and exhaust valve mainly comprises valve body, is connected with valve body, valve body coordinates with valve gap in the holding cavity forming and is provided with mangetic core assembly, mangetic core assembly comprises floating drum cover, floating drum, micro-comb and valve block, wherein floating drum cover is fixedly connected with valve body, floating drum is arranged in floating drum cover and offsets and coordinate with the bottom of micro-comb, the top of micro-comb is passed valve gap and is stretched out in the outside of valve body, valve block is fixedly installed on micro-comb, valve gap is provided with the relief opening coordinating with valve block, and the bottom of floating drum cover is provided with opening.Its working principle is: when to blank pipe water-filling, the air in pipeline, under the effect of hydraulic pressure, in above-mentioned opening enters floating drum cover, and is discharged from the relief opening of valve gap; When in pipeline, current increase gradually, floating drum drives micro-comb to rise under the effect of hydraulic pressure, until valve block and relief opening close contact, now exhaust close; While assembling micro-air in pipeline, floating drum moves downward slightly under the effect of micro-air pressure, makes to occur certain interval between floating drum and micro-comb, and now the minimum gas in pipeline is discharged through micro-comb, until after air scavenge, floating drum and micro-comb be close contact again; When in pipeline, the water yield reduces, floating drum declines with water level, and micro-comb band moving valve plate synchronously declines with floating drum, and valve block and relief opening depart from, and outside air enters in valve body, realizes breathing process.
Yet, the defect of above-mentioned air inlet and exhaust valve is: first, owing in floating drum cover bottom, opening being set, when to blank pipe water-filling, can make large quantity of air in opening enters floating drum cover, make floating drum be subject to gas and impact and blown afloat the rapid rising of band moving valve plate and stop up relief opening, cause gas normally not discharge; The second, because the top of floating drum and the bottom of micro-comb directly contact, cause the area of contact between floating drum and micro-comb less, make sealing effect poor; The 3rd, because existing valve structure arranges unreasonablely, cause valve block to contact defective tightness with relief opening, cause plugging effect poor.
