Model utility content
The utility model proposes a kind of solidifying water one-way valve of releasing, solve the deficiency of the solidifying water draining technology of prior art central air-conditioning system, this one-way valve structures is simple, easy to maintenance, stable performance, make the draining of central air-conditioning system cooler or dehydrater more convenient, effectively prevent the impact of circulation of air on solidifying water discharge.
The technical solution of the utility model is achieved in that
A kind of solidifying water one-way valve of releasing, comprise inlet union, outlet connection, connect base and cylindrical shell between described inlet/outlet joint, described inner barrel, be positioned at sealing seat is set on base, on described sealing seat, contact is combined with sealed ball float, described sealed ball float top arranges ball float baffle plate, is connected with the guide rod of guiding ball float moving direction between described ball float baffle plate and base.
Described ball float baffle plate is provided with multiple guide rod positioning holes and a vent, and the rib of multiple regular arrangement is set, and described ball float baffle plate middle part arranges the arc identical with described sealed ball float diameter.
Between described base and cylindrical shell, for flange is connected, and be furnished with Sealing, positive stop lug boss is set on base.
Between described base and inlet union, between described outlet connection and described cylindrical shell, be and be welded to connect.
Described sealing seat is interior truncated cone shape sealing seat, is convenient to contact cooperation with described sealed ball float, and sealing seat is fixed by sealing seat gland.
Further, described sealing seat external frame is cylindrical body, and interior profile is round platform, and sealing seat is located by positive stop lug boss and sealing seat gland.
Described cylindrical shell top or top-side arrange described outlet connection.
Further, described sealed ball float is placed in the cavity of described ball float baffle plate, each guide rod and sealing seat gland formation, and two adjacent guide rod spacing are less than described sealed ball float diameter.
Working principle of the present utility model is:
In the time of solidifying water following current, solidifying water enters inner barrel from lower inlet joint, and ball float is pushed up from sealing seat by the pressure of bottom current, solidifying water space between rib on ball float baffle plate flow to cylindrical shell top, flow out from outlet connection, after solidifying water discharge is stable, spheroid embeds in the arc of ball float baffle plate;
In the time entering from inlet union without solidifying water, ball float falls after rise to sealing seat by deadweight, and under deadweight and air pressure effect, press seal seat is realized sealing non-return.
The beneficial effects of the utility model are, for the draining of central air-conditioning system air-cooler or dehydrater, can effectively prevent the impact of circulation of air on solidifying water discharge, possess advantage simple in structure, easy to maintenance, that physical life is long.
