Practical novel content
It is poor that technical problem to be solved in the utility model is to provide a kind of adjustment refrigerator external and internal pressure, makes air pressure balance and can ensure the unidirectional air pressure balance valve that in refrigerator, food never degenerates.
The utility model adopts following technical scheme:
The valve body that the utility model comprises equilibrium valve housing and is arranged in housing; Described equilibrium valve housing one end arranges inlet mouth, and described equilibrium valve housing the other end sidepiece sets out gas port; Valve seat is fixedly mounted at described equilibrium valve housing inner chamber; Described valve seat side is the first room, chamber, and another side of described valve seat is the 2nd room, chamber, described inlet mouth and the first chamber, described air outlet and the 2nd chamber; Arranging open holes on described valve seat, arrange more than one ventilating pit around open holes, the valve lever clearance of described valve body is arranged in open holes, and the bonnet of described valve body is positioned at the 2nd indoor, chamber and covers on ventilating pit.
The utility model inserts dress insect protected air inlet net at the entrance end of described inlet mouth, and the exit end in described air outlet inserts dress escape pipe.
First cover plate of room, the utility model first chamber and the activity of equilibrium valve housing are arranged; 2nd cover plate of described 2nd room, chamber and the activity of equilibrium valve housing are arranged.
The utility model ventilating pit is evenly arranged on valve seat, and ventilating pit is 4.
The utility model positively effect is as follows: the utility model is arranged on the cabinet door of refrigerator, can effectively solve the pressure equilibrium of refrigerator inside and outside, reduce the waiting time opening cabinet door, it may also be useful to be convenient, equilibrium valve housing and valve body are inserted load and are connect, structure is simple, and the first cover plate and the 2nd cover plate are flexibly connected with equilibrium valve housing, installation, dismantles and easy to maintenance, overall employing injection molding, in use can not getting rusty, it is to increase work-ing life, production cost is lower; It is indoor that outside air enters the 2nd chamber by ventilating pit, the pressure inside and outside balance refrigerator, and the bonnet of valve body covers on ventilating pit, when pressure equilibrium, makes valve base sealing good; Insect protected air inlet net can effectively prevent foreign matter and mosquito from entering in refrigerator body by inlet mouth when every day use, keeps food quality, the pressure reduction of the automatic surge tank inside and outside of the utility model, making air pressure reach internal and external equilibrium, novel structure, cost is low, simple and practical, easy installation and removal.
