Abstract
A non-return valve for fume central exhaust system of high rise residence comprises a valve body pipeline 1, a filter screen 2, a seal ring 3, a non-return sheet 4, a spring 5 and a rotating shaft 6, which is characterized in that: the oil-gas filter screen is arranged inside a gas inlet of the valve body pipeline; an inclined plane is arranged outside a gas outlet of the valve body pipeline; the non-return sheet fitting the inclined plane is arranged on the inclined plane; the lower end of the non-return sheet is provided with the rotating shaft connected with a bracket shaft sleeve at the lower end inclined plane of the gas outlet of the valve body pipeline; the spring used to close the non-return sheet of the gas outlet is arranged on the rotating shaft; when a switch of an oil smoke exhaust machine is turned on, oil-gas flow passes through the filter screen for filter, overcomes the pressure of the spring, opens the non-return sheet and enters into a flue 9.
Description
The utility model relates to a kind of building house kitchen, toilet fume centralized releasing system fume emission, stops the check valve of common duct smoke backflow.
At present, the check sheet shaft fulcrum is closed the air outlet in the upper end, air outlet by check sheet gravity on the known dwelling house fume centralized releasing system check valve air outlet, uses the back because on greasy sticking shaft fulcrum and the check sheet, influence the check sheet closing function, and resistance is big, air displacement is little.
The purpose of this utility model provides a kind of oil gas in the flue gas can the filtration in advance, can effectively house kitchen flue gas and toilet foul smell be discharged into public air outlet flue, stops each layer kitchen and the mutual gas blowby of toilet flue gas to scurry the generation of flavor phenomenon.
Technical solutions of the utility model are following nutation type check valves, comprise conduit, filter screen, check sheet, it is characterized in that: the conduit suction port has the hydrocarbon filter net, the conduit air outlet is an inclined-plane, the check sheet that has a slice at least to cooperate on the inclined-plane with the inclined-plane, the check sheet lower end has rotating shaft to be connected with lower end, conduit inclined-plane rack sleeve, and spring is housed in the rotating shaft.
The utility model has the advantages that oil smoke gas filters in advance between the kitchen, the conduit air outlet is an inclined-plane, and check sheet cooperates with the inclined-plane, and rotary shaft rack is equipped with spring in the lower end, inclined-plane in the rotating shaft, and effectively valve body pipeline air outlet stops smoke backflow.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the utility model embodiment one a structural representation.
Fig. 2 is the utility model embodiment two a structural representation.
The utility model embodiment one comprises conduit 1, filter screen 2, seal ring 3, check sheet 4, spring 5, rotating shaft 6, pull bar 7, electromagnet 8, it is characterized in that: in conduit 1 suction tude filter screen 2 is housed, check sheet 4 and seal ring 3 are equipped with in place, conduit 1 air outlet, rotating shaft 6 upper springs 5 compress check sheet 4 and seal ring 3, valve body pipeline 1 air outlet effectively stops dwelling house fume centralized releasing system common duct smoke backflow.But dwelling house fume centralized releasing system cooker hood switch open, 8 adhesives of conduit 1 bottom electromagnet, pulling pull bar 7 overcomes spring 5 pressure and opens check sheet 4, and flue gas filters by conduit 1 inner filtration net 2, enters common duct 9.
The utility model embodiment two comprises conduit 1, filter screen 2, seal ring 3, check sheet 4, spring 5, rotating shaft 6, it is characterized in that: in conduit 1 suction tude filter screen 2 is housed, check sheet 4 and seal ring 3 are equipped with in place, conduit 1 air outlet, rotating shaft 6 upper springs 5 compress check sheet 4 and seal ring 3, valve body pipeline 1 air outlet effectively stops dwelling house fume centralized releasing system common duct smoke backflow.But dwelling house fume centralized releasing system cooker hood switch open, air communication are crossed conduit 1 inner filtration net 2 and are filtered, and overcome spring 5 pressure and open place, conduit 1 air outlet check sheet 4, enter common duct 9.
