Embodiment Construction

[0044] like Figure 1-Figure 12 As shown, the electromagnetic check valve for common flue of the present invention includes a base 1 , a cylinder body 2 , a valve core 3 and a one-way valve plate 4 arranged in the cylinder body 2 , and a diameter reducing ring 5 .

[0045] The outer periphery of the base 1 is a twenty-four diamond-shaped cut surface, and has a connecting ring 11, and the connecting ring 11 is provided with a clamping groove 12 for engaging the cylinder. Inserting one end of the cylinder body 2 into the card slot 12 can easily connect the cylinder body 2 to the base 1 . The base 1 is also provided with screw holes 13, and the base 1 can be fixed on the wall by bolts.

[0046] The inner part of the cylinder body 2 is a cylinder, and the outer part is a dodecagonal cylinder. A detachable connection is formed between the base 2 and the cylinder body 1 through a slot. The cylindrical body 2 is provided with a circular retaining ring 21 for preventing the one-way...

Abstract

The invention discloses an electromagnetic check valve of a common flue. The electromagnetic check valve comprises a base, a barrel body, a valve element, a one-way valve block and a reducing ring, wherein the valve element and the one-way valve block are arranged in the barrel body. The electromagnetic check valve is characterized in that an electromagnetic device is arranged on the valve element, and an iron sheet is arranged at the position, corresponding to the electromagnetic device, of the one-way valve block; the electromagnetic device comprises an electromagnet, and a common magnet is fixed at the top of the electromagnet. When a smoke exhaust starts to work, the electromagnetic device is in the power-on state, magnetic fields of the electromagnet and the common magnet are offset, magnetic force of the electromagnetic device is lost, and the one-way valve block can be freely opened. Air flow with cooking fumes passes through an air inlet and a cooking fume channel to push the one-way valve block open, and the cooking fumes are discharged into the common flue. When the smoke exhaust stops working, the electromagnetic device is in the power-off state, the magnetic force of the electromagnetic device is recovered, the electromagnetic device and the iron sheet on the one-way valve block are attracted, the one-way valve block falls to the position of a circular stopping ring of the barrel body under the effects of suction force of the magnet and the gravity of the one-way valve block, the cooking fume channel smoke channel and the common flue are separated to form complete sealing.

Description

technical field [0001] The invention relates to a public flue check valve used for public flues to prevent odors caused by the backflow of oil fume and dirty gas, in particular to a public flue electromagnetic check valve. Background technique [0002] Nowadays, there are more and more high-rise residential buildings, and the pollution caused by smoke and odor in kitchens and bathrooms is becoming more and more serious. Experts pointed out that kitchen fume contains a lot of harmful substances, such as carbon monoxide, sulfur dioxide, nitrogen oxides and so on. The concentration of harmful substances in oil fume is higher than the nationally specified atmospheric indicator multiples: 5 times that of carbon monoxide; 14 times that of sulfur dioxide; 5 times that of inhalable dust; 2.4 times that of the strong carcinogen pyrene. Housewives are much more likely to develop lung cancer due to kitchen fumes than smoking. [0003] The odor and peculiar smell in the bathroom is a ...
