Abstract
The utility model relates to a check valve which is used for keeping an oil-smoke from returning in a kitchen or a washroom. The utility model comprises a connecting seat which can be fixed on a venting channel outlet and a valve body arranged on the connecting seat. A boss air cylinder which can extend into an inner cavity of a valve body (4) for sleeving and can extend axially is arranged on a connecting seat (2) which is connected with an under-pan of the valve body (4). A valve slice (3) which is sealed between the valve body (4) and the boss air cylinder of the connecting seat (2) is movably arranged in a groove on an end chord line of the boss air cylinder. In an installation process of the check valve of the utility model, the connecting seat is not needed to be inserted into a hole of a flue or a venting channel and then a changing to apertures of installation holes on the venting channel can be avoided, which can enhance convenient and prompt installation. The valve slice arranged at the middle part of the valve body has free moving width, which can prevent an impulse of the exhausted oil-smoke vented by habitants of lower floors from leading the valve slice to conflict with the inner wall, and a block valve can be automatically opened. The utility model can solve the problem of normal smoke fleeing.
Description
1. technical field
The utility model relates to and a kind ofly is used to prevent that the waste gas oil smoke from returning the safety check of scurrying, in particular for the safety check of kitchen or toilet discharging oil smoke, waste gas.
2。Background technique
Be used in the known technology prevent that oil smoke, waste gas from returning the safety check of scurrying, mostly body is big, and complex structure takies duct space, installation requirement height, the defective that exists flue gas to return to scurry.24 days the disclosed the 00266250th October calendar year 2001 of Chinese patent.No. 7 patents " kitchen, toilet disengaging fire-preventing check valve ".The exhaust outlet that the air exhaust channel of packing into is arranged will be left a mounting hole that is complementary with the exhaust outlet size when this exhaust outlet is installed on the air exhaust channel wall.Installation is wasted time and energy, inconvenience.Valve sheet in this safety check leans in the inlet end inwall of the valve body hypotenuse that meets at right angles, and the revolution degrees of freedom is little, is hindered dead and can not open automatically as spring by resident family of lower floor discharged flue gas often, produces back and scurries flue gas.
3. model utility content
The utility model provides a kind of easy for installation, quick at problems of the prior art, need not stretch into flue air port inwall, can prevent the safety check that the impact resistance block valve of lower floor discharging air flue upper punch flue gas is opened.
Above-mentioned purpose of the present utility model is achieved in that and a kind ofly is used to prevent that oil flue waste gas from returning the safety check of scurrying, prevent that especially for kitchen, toilet oil flue waste gas from returning the safety check of scurrying, comprise a connecting base and the valve body that is contained on the connecting base that can be connected and fixed on the ventilation channel outlet, it is characterized in that: the connecting base 2 that connects valve body 4 chassis has one can stretch into valve body 4 inner chambers and cooperate the boss inflator that extends vertically that is inserted in, and is encapsulated in valve sheet 3 between valve body 4 and the connecting base 2 boss inflators and is installed in versatilely in the groove on the boss inflator port string of a musical instrument.
In a preferred embodiment, can in the contiguous suction port of valve body, lay filter screen, to reduce the accumulation that oil gas is detained pipeline.
In another preferred embodiment, valve body suction port end is made a sliding-rail groove, its bottom is separated with valve body, the bottom disc has the air inlet nozzle, inserts sliding-rail groove slidably.
The utility model compared with prior art has following advantage and beneficial effect:
Adopt safety check of the present utility model, in installation process, owing to connecting base need not be inserted flue or air channel cinclides, thus avoided air exhaust channel is installed the selection in cinclides aperture.Increased the convenience and the agility of installing, not only saved time but also laborsaving.The valve sheet and its intracavity diameter that are installed in the valve body middle part are roughly suitable, and freedom of movement is wide, can prevent that the impulse force of resident family of lower floor discharging oil flue waste gas from causing valve sheet friction inwall, and block valve is opened automatically, has solved the smoke blowing problem.The overanxious net that adopts also can reduce oil gas and be detained the accumulation of formation oil droplet, makes valve passage be easy to clean.The valve body suction port is made sliding-rail groove, sliding plug inlet hole connecting tube, and it is more convenient that demolition is cleaned, thereby need not the demolition valve body.
4. description of drawings:
Fig. 1 is the utility model structural representation
5. mode of execution:
Fig. 1 shows the safety check that the utility model is made by metal or PVC plastic processing, this device comprises a connecting base 2 that is connected and fixed on air exhaust channel or the smokejack 1, be shaped on some fastener holes on the dish type that connecting base 2 radially extends, fastener hole by screw on the outer wall in the air channel 1 that has mounting hole.Connecting base 2 middle parts are shaped on radially extends, and deviates from the boss inflator of air draft road junction outer wall.Raised head face is shaped on the groove of laying valve sheet 3, and groove is higher than the diameter string of a musical instrument.Valve body 4 lower ends are shaped on the installation seat surface that radially extends, and are shaped on the fastener hole that is connected with connecting base number together on the seat surface, make it to be installed on the outer wall of air draft road junction.For strengthening body strength, can also be shaped on stiffening rib around the valve body.Can be shaped on the filter screen 5 of insertion valve body 4 illustrated in fig. 1 at valve body 4 contiguous suction port places, filter screen 5 can adopt built-in.Lubricating cup is equipped with in the valve body below.The utility model can also be made sliding-rail groove with valve body suction port end, has the air inlet nozzle with bottom after valve body separates, is slidably inserted in the sliding-rail groove.Retracting and when cleaning with the installation that makes things convenient for tracheae.In order to prevent to scurry cigarette better, the utility model can also be installed a magnetic patch at the opposite side wind passage mouth top edge of valve sheet, makes it under dead status, and closed airway forfends and scurries cigarette automatically.
Claims (3)
1. one kind is used to prevent that oil flue waste gas from returning the safety check of scurrying, especially for preventing between Kitchen hygiene that oil flue waste gas from returning the safety check of scurrying, comprise a connecting base and the valve body that is contained on the connecting base that can be connected and fixed on the air exhaust channel outlet, it is characterized in that: the connecting base (2) that connects valve body 4 chassis has one can stretch into valve body (4) inner chamber and cooperate the boss inflator that extends vertically that is inserted in, and is encapsulated in valve sheet (3) between valve body (4) and connecting base (2) the boss inflator and is installed in versatilely in the groove on the boss inflator port string of a musical instrument.
