Abstract
The invention discloses a check valve which comprises a valve casing. An air inlet and an air outlet are placed on the valve casing, wherein the air inlet and the air outlet can be respectively connected with an external air exhaust pipe in a sleeved mode. A check plate is detachably connected between the air inlet and the air outlet. At least one check sheet is connected on the check plate in a hinge mode, wherein the check sheet is capable of opening/ closing to break over/ block off a channel between the air inlet and the air outlet. The air inlet and the air outlet of the check valve are capable of being directly connected with the external air exhaust pipe in a sleeved mode, and therefore mounting positions in a kitchen smoke exhaust system of the check valve can be changed. The air outlet of the check valve is communicated with an air inlet of a sharing air exhaust duct through a connecting air exhaust pipe, and the air inlet of the check valve is communicated with an air outlet of a kitchen ventilator through the connecting air exhaust pipe. Therefore, the check valve is placed below a suspended ceiling and above the kitchen ventilator, and accordingly the check sheet stuck by waste oil can be replaced and washed without removing the suspended ceiling and the kitchen ventilator, and safety and reliability of use functions of the smoke exhaust system are effectively guaranteed.
Description
Technical field
The present invention relates to dwelling house exhaust structure technical field, more particularly, relate to a kind of safety check for kitchen exhaust gas system.
Background technique
At present, be unable to do without the safety check that is used for the system's conducting of control smoke exhaust and closes in the smoke exhaust system in kitchen.This safety check one end is provided with fixed hole position, and the other end is without fixed hole position.During installation, safety check one end is located by suction port place and range hood air outlet that fixed hole position is installed on the building shared flue gas exhaust pipeline, and an end of not establishing fixed hole position is connected with outlet pipe.Adopt the smoke exhaust structure recent two decades of this safety check to come not change all the time.But along with the raising that people require finishing, present kitchen substantially all is equipped with furred ceiling, and the suction port of shared flue gas exhaust pipeline is located in the furred ceiling.When safety check is installed on the suction port of shared flue gas exhaust pipeline, during non-return sheet on the cleaned and changed safety check, need to remove furred ceiling; And be installed on the safety check of range hood air outlet, because limited space in the range hood, during non-return sheet on the cleaned and changed safety check, need the dismounting body.So adopt the safety check of said structure, maintenance, maintenance, replacing trouble, so the user does not clean safety check basically, just caused greasy dirt to accumulate in the safety check, make the normal closure of safety check and open function malfunctioning, cause the discharge stir-frying in kitchen flue gas of smoke exhaust system and prevent that the interior flue gas of exhaust duct from pouring in down a chimney the disabler into the kitchen.And at present, oil smoke arrange not gone out during cooking, and the cooking of others' family distinguish the flavor of pour in down a chimney into the phenomenon in kitchen very general, but the user does not know the reason place, causes the user to live in for a long time by in the indoor air of cross pollution.
Summary of the invention
