Abstract
An anti-damping-smoke air outlet valve of an air outlet pipe shared by dwelling houses relates to the technology field of controlling structure of air supply or air inducing. The disclosed anti-damping-smoke air outlet valve is provided with a once-through valve box. One or more sheets of valve boards are installed inside the valve box, and the joint position of the valve boards is sealed by overlapping cylinder surfaces. The periphery of the valve box is fixed with a decorating board provided with a screw guide cylinder and a rubber sealing ring. The air inlet end of the valve box is inlaid with cleanable oil absorption nets. The lower end of the valve box is connected with an oil collecting cup. The utility model has the advantages of good sealing property, environment protection, oil removing, convenient maintenance and beautiful appearance. Further, the installation of the utility model is not limited by the thickness of the decoration layer of the air outlet pipe.
Description
The anti-smoke blowing outlet valve of the shared air outlet flue of a kind of dwelling house relates to the technical field of controlling air-supply or citation damper door.
The existing anti-smoke blowing outlet valve that is used for air outlet flue is made up of straight-through type clack box, valve plate, catchment cup.Its valve plate seam crossing is a plane sealing, and sealing effect is bad, and flue gas can recharge by the place, slit.
The purpose of this utility model is in order to prevent that flue gas from recharging from the valve plate slit.
The utility model is to imagine in existing anti-smoke blowing outlet valve, changes the valve plate seam crossing in the clack box into the cylndrical surface sealing by plane sealing, and promptly the seam areas at valve plate seals by the cylndrical surface joining.Therefore, the utility model is made up of straight-through type clack box, cylndrical surface sealing configuration, valve plate, catchment cup.Wherein: valve plate has 1 or multi-disc.
In order to hide inaesthetic installation seam, can outside clack box, load onto decorative sheet;
From seam leakage is installed, can on decorative sheet, load onto rubber seal in order to prevent flue gas;
In order to absorb the greasy dirt in the flue gas, can also be at the nested oil suction net of air inlet sleeve pipe jointing;
In order to guide the installation screw in place, make outlet valve that the influence that is not subjected to decorating layer thickness is installed, so that select the installation screw of appropriate length, the screw guide can also be housed on decoration panel;
Below in conjunction with accompanying drawing and example, the utility model is described in further detail.
Fig. 1 is wherein a kind of schematic representation of structure of the utility model.
Schematic representation when Fig. 2 is to use the cylndrical surface sealing.
This outlet valve has a straight-through type clack box (1), and two valve plates (2) are installed in the clack box (1), and the seam areas of two valve plates (2) is by cylndrical surface (3) joining sealing up and down; Venner plate (4) is being fixed in clack box (1) periphery, is used to hide the installation hole of outlet valve, decoration panel (4) be shaped as round rectangle, have screw guide (5) on the decoration panel (4), guiding is installed screw outlet valve is fixed; Also have rubber seal (6) on the decoration panel (4), the flue gas that prevents air outlet flue is to external leakage; The inlet end of clack box (1) nested oil suction net capable of washing (7), the greasy dirt in the filtering flue gas plays the effect that purifies air; The bottom of clack box (1) is connected with catchment cup (8), collects the greasy dirt in the valve body.Clack box (1) inlet end is a circular cross-section, can socket-connect with resident family's outlet pipe, and clack box (1) exhaust end is the inequilateral hexagonal section.
When gas outlet means was opened by resident family, the unclean air in the room was delivered to anti-smoke blowing outlet valve by outlet pipe, and wind-force blows valve plate open, gets final product exhaust; When resident family's manipulation gas outlet means was out of service, the valve plate of anti-smoke blowing outlet valve is sealing voluntarily under action of gravity, can prevent smoke backflow.
The advantage of anti-smoke blowing air bleeding valve of the present utility model is: hermetically-sealed construction is reasonable, anti-smoke blowing Taint of odour is effective; Adopt oil suction net capable of washing, had the environment-friendly function of air cleaning; Be connected and fixed by screw, the installation site can be adjusted flexibly; Used decoration panel, outward appearance Elegant in appearance.
