Intelligent kitchen and bath fireproof check valve

Abstract

The invention provides an intelligent kitchen and bath fireproof check valve. A valve base, a valve way, a check valve plate arranged in the valve way and an intelligent controller arranged on the valve base and connected with the check valve plate are included. The valve way is internally provided with a valve ring coaxial to the valve way, and the thickness of the check valve plate is smaller than that of the valve ring. When the check valve plate is axially perpendicular to the valve way, the two surfaces of the check valve plate are located in the two ends of the valve ring correspondingly, and the diameter of the check valve plate is equal to the inner diameter of the valve ring. One end of a pin shaft axially perpendicular to the valve way penetrates through the valve ring and then is inserted in the check valve plate, and the other end of the pin shaft is connected with the intelligent controller. The valve ring is arranged between the valve way and the check valve plate, the diameter of the check valve plate is equal to the inner diameter of the valve ring, the check valve plate and the valve ring can be in spherical seamless connection, the closing tightness of the check valve is greatly improved, backflow of smoky gas is effectively prevented, and the safety performance of the intelligent kitchen and bath fireproof check valve is greatly improved.

Description

technical field [0001] The invention relates to a check valve, in particular to an intelligent fireproof check valve for kitchen and bathroom. Background technique [0002] With the development of urbanization and the gradual improvement of people's living standards, more and more people enjoy the convenience and superiority of urban life. However, the high-density gathering of urban population also has many potential safety hazards. Due to the frequent use of fire, the kitchen is an extremely dangerous place. On the one hand, the reason is people's operating errors, and the more important reason is that the safety of kitchen equipment is insufficient, and the prevention of disasters is not comprehensive. [0003] When people cook in the kitchen, a lot of oily fumes will be generated, and these oily fumes will be exhausted into the preset flue in the building through the range hood. Unsmooth smoke or even oil fume pouring back, which not only damages the kitchen environmen...

AI Technical Summary

Problems solved by technology

The Chinese invention patent with the publication number CN104482256A discloses an intelligent kitchen and bathroom fireproof check valve. The valve uses an intelligent control chip and a micro switch sensor to control the opening and closing of the check valve. However, since all its operating signals are based on circuit voltage, Only the control of the check valve has been optimized, but the sealing performance of the check valve is not tight enough, and the situation of flue gas backflow is easy to occur in the closed state, and there is no effective prevention for the situation where the flue temperature is too high, it is difficult to prevent long-term The fire caused by the time opening and the temperature in the flue is too high; and once the power supply fails, all functions will stop, and the oil smoke backflow and fire are inevitable
