In order to achieve the above object, the utility model adopts the following technical scheme: the utility model provides a flue check valve, includes mount pad, rubber circle, separation blade and valve body, the mount pad is connected with the valve body, and the separation blade setting circles at rubber, the valve body inboard is equipped with the fender ring of slope, and the rubber circle sets up on keeping off the ring.

Preferably, the included angle between the baffle ring and the inner wall of the valve body is 30-75 degrees.

Preferably, the inner side of the rubber ring is provided with a groove, and the baffle plate is embedded in the groove.

Preferably, the middle part of the baffle ring is provided with a beam, and the rubber ring is arranged on the beam through a fixing plate.

Preferably, the two ends of the cross beam are provided with mounting columns, the two ends of the rubber ring are provided with through holes, and the rubber ring is mounted on the cross beam through the through holes and the mounting columns.

Preferably, the mounting seat is provided with a positioning groove, the valve body is provided with a positioning key, and the mounting seat is connected with the valve body through the positioning groove and the positioning key.

Compared with the prior art, the beneficial effects of the utility model reside in that: the structure is simple, the durability is high, the sealing performance is good, and the application range is wide; the elastic rubber ring is adopted to replace a traditional reset spring, the rubber ring is easy to recover after being deformed, the sealing performance is good, and the noise of opening and closing is low; the baffle ring is obliquely arranged on the inner side of the valve body, so that the rubber ring and the baffle can be reset by utilizing the elasticity and gravity of the rubber ring and the baffle after being opened, and the whole transverse and longitudinal installation can be adapted; the groove at the inner side of the rubber ring is convenient for dismounting and replacing the baffle sheet; the through holes at the two ends of the rubber ring and the mounting columns at the two ends of the cross beam enable the rubber ring to be conveniently and quickly disassembled, assembled and replaced; the positioning groove on the mounting seat and the positioning key on the valve body enable the valve body to be conveniently and quickly disassembled.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by the ordinary skilled person without creative work all fall into the protection scope of the present invention.

As shown in fig. 1-5: the utility model provides a flue check valve, includes mount pad, rubber circle, separation blade and valve body, the mount pad is connected with the valve body, and the separation blade setting circles at rubber, the valve body inboard is equipped with the fender ring of slope, and the rubber circle sets up on keeping off the ring, plays sealed effect. The angle alpha between the baffle ring and the inner wall of the valve body is 75 degrees, so that the rubber ring and the baffle can reset by gravity after being opened. The inboard recess that is equipped with of rubber circle, the separation blade inlays in the recess, and easy dismounting also further promotes the leakproofness. The middle part of the baffle ring is provided with a crossbeam, the rubber ring is arranged on the crossbeam through a fixing plate, and two ends of the rubber ring can be lifted upwards. The crossbeam both ends are equipped with the erection column, and rubber circle both ends are equipped with the through-hole, and the rubber circle passes through the through-hole and the erection column is installed on the crossbeam, dismouting, change rubber circle convenient and fast. Be equipped with the constant head tank on the mount pad, be equipped with the navigation key on the valve body, the mount pad passes through the constant head tank with the valve body to be connected with the navigation key, dismouting valve body convenient and fast.

As shown in fig. 6-7: the product can be longitudinally arranged in a pipeline above the range hood and also can be transversely arranged at the tail end of the pipeline. When the oil smoke exhausting device works, oil smoke is exhausted into the pipeline through the oil smoke exhaust ventilator, when the oil smoke flows through the oil smoke exhausting device, the rubber ring and the blocking piece are washed away by the upward oil smoke, and air flow flows through the two sides. When the range hood stops working, the rubber ring is easy to reset due to the elasticity of the rubber ring, the rubber ring and the blocking piece fall back and close under the action of gravity, and the rubber ring impacts the blocking ring to generate smaller noise.
