Abstract
The utility model discloses an oil-fume-exhausting fireproof check valve comprising a connecting plate, a support, a valve body, a baffle, a limiting plate, a fuse wire and a locating support, wherein the valve body is arranged on the connecting plate, the support is disposed in the valve body, the baffle can be arranged on the connecting plate in a rotary mode, the limiting plate is arranged in the valve body, and two ends of the fuse wire are connected between the locating support and the limiting plate in a fusing mode. The oil-fume-exhausting fireproof check valve is easy to install and fix. A valve piece can extend and retract by 70 degrees, is smooth in discharging and fireproof and is in fuse connection, two heads of the valve piece can be fused during a fire, and the aim of thoroughly closing the valve piece is achieved.
Description
Technical field
The utility model relates to the cooking-fume discharging field, relates in particular to a kind of oil extraction flue gas fire-preventing check valve.
Background technique
In buildings such as high residential building, apartment, all design and installation has public oil extraction, cigarette, gas passage.The smell that respectively occupies kitchen fume, the toilet at family all discharges by the mode that connects common-use tunnel.In discharge process, need avoid the refluence of oil, cigarette, gas, also to prevent that highway from producing fire trouble because of the deposition grease simultaneously.At present extensively the technology that adopts is to reach the purpose that the flue gas that prevents in the gas flue pours in down a chimney and Avoids Tainting advancing flue gas mouth arranged outside one-way valve.And, now the exhaust gas flue of structure normally is combined into one with the one-way valve of outside at the fire-closing valve of the interior survey setting of suction port, it is fixed with the gas flue wall in the suction port inboard, thereby have following problem: 1 after using certain hour, the dirty incrustation of cigarette can produce and be not closed completely, thereby can cause the purpose that does not have resistance cigarette, retaining gas; 2 install and can't fixedly positioning, and influence using effect; 3 fire prevention fuse pieces are unidirectional connections, are difficult for when running into the condition of a fire disconnecting, and are difficult to play fully flameproof effect
Therefore, need provide a kind of oil extraction flue gas fire-preventing check valve to address the above problem.
The model utility content
In order to address this problem, the utility model discloses a kind of oil extraction flue gas fire prevention non-return, described oil extraction flue gas fire-preventing check valve comprises connecting plate, support, valve body, baffle plate, limiting board, fusible link and locating support, described valve body is arranged on the described connecting plate, and described support is arranged in the described valve body, and described baffle plate is arranged on the described connecting plate rotationally, described limiting board is arranged in the described valve body, and the two ends welding of described fusible link is between described locating support and described limiting board.
Preferably, described fusible link is fixing by the double end welding.
Oil extraction flue gas fire-preventing check valve of the present utility model is easily installed, fixing, and the valve block hypertonic can reach 70 °, discharge smooth and easyly, and thread connection is adopted in fire prevention, and when running into the condition of a fire, double end fuses rapidly, plays the purpose of closing valve block fully.
Introduced the concept of a series of reduced forms in the model utility content part, this will further describe in the embodiment part.The utility model content part does not also mean that key feature and the essential features that will attempt to limit technological scheme required for protection, does not more mean that the protection domain of attempting to determine technological scheme required for protection.
