Abstract
A house exhaust duct transmission check valve relates to an exhaust duct checking a down draft of house building kitchen, being composed of a gas cylinder, a lampblack air inlet, a valve piece, a spring seat cover. Presenting squareness, the lower end of the gas cylinder is conical shape and one surface is square diagonal cut joint while the other surface is round opening, there being an arc-shaped guide way at the middle part inside the cylinder. Being a cylinder shape, one end of the lampblack air inlet is level and the other end is a small bugle shape. There is a fixing board around an opening external diameter and the small horn-shaped opening end and the gas cylinder round opening are welded matching with each other. The lower part centre of one surface of the square valve piece is provided with a spring seat, standing vertically naturally at the small horn-shaped opening of the lampblack air inlet. There is a hem at the both sides of the square spring seat cover with a screw hole at the both sides of the hem and there is a square opening at the lower part centre. The spring seat and the square opening are welded to compose the spring seat cover whose four sides are matched and fixed with the gas cylinder square diagonal cut joint by means of the screw. One end of the spring is matched and fixed with a cote of the valve piece spring seat and the other end is matched and fixed with the spring seat of the spring seat cover, which can prevent the down draft effectively.
Description
Affiliated technical field:
The utility model relates to dwelling house air exhaust channel transformation check valve, especially residential building kitchen air exhaust channel check collaborate, the check valve of down draught.
Background technique:
Urban House has been a trend to the high level development, and the cooking-fume discharging problem of all kinds of residential buildings solves bad always.According to building standard several years ago, the oil extraction flue gas in residential building kitchen is just discharged by being provided with a common air flue.Facts have proved only have air flue can not reach the effect of oil extraction flue gas, oneself discharges by venting gas appliance by oil smoke gas, goes here and there but other oil smoke gas is mixed upstairs, downstairs, and often the venting gas appliance through your family enters into your family, is subjected to the pollution of oil smoke gas.The patented technology (01267577.6) that State Patent Office disclosed a kind of " pressure-varying air-exhausting duct ".This technology in use has certain resistance cigarette effect, but finds to still have deficiency in construction.At first, itself just has the slit sharf of this technology, can not driving fit, and gas leak phenomenon can not be avoided, and has reduced resistance cigarette effect.Two. the valve disc sheet is by the gravity rod return.After using a period of time, each position must be stained with oily thing, and the weight of gravity rod is difficult to valve disc sheet return, bad sealing gas leakage, and effect is not good naturally.Three. this device be with the building flue be one, and protrude planomural in the flue, when building a building, must install simultaneously.Build drop unavoidably when high level is constructed lime-ash, fragment of brick, the big object that drops easily breaks its device; Little object, stops up guide pipe at Yi Tianman, causes the valve disc sheet not open and loses effect.
Summary of the invention:
In order to solve the deficiency of above technology, the utility model provides a kind of dwelling house air exhaust channel transformation check valve, relies on object deadweight sealing, does not need any page or leaf hinged, reduces the slit, and the realization check is scurried the purpose of cigarette.
The technical scheme in the invention for solving the technical problem is by gas cylinder, oil-feed flue gas mouth, valve block, the spring flap constitutes, gas cylinder is the square cylindrical shell, it is tapered that the lower end is, one side is square diagonal cut joint, face is a circular open in addition, there is arc-shaped guide rail at the middle part in the tube, oil-feed flue gas mouth is cylindric, one end is flat mouthful, and end is the toy trumpet mouth in addition, and a mouthful outer-diameter ring circumference has fixed plate, toy trumpet mouth end cooperates solid welding with the gas cylinder circular open, valve block is square, and the one side lower central has spring seat, stands naturally in the toy trumpet mouth place of oil-feed flue gas mouth, the spring flap is a square, there is flanging on both sides up and down, and there is a hole at the flanging two ends, and lower central has a square opening, spring seat cooperates solid welding to constitute the spring flap with square opening, spring flap four limits cooperate screw fastening with the square diagonal cut joint of gas cylinder, and spring one end cooperates fixing with the nest of valve block spring seat, and it is fixing that spring holds the nest of the spring seat that covers with spring seat to cooperate in addition.
The beneficial effects of the utility model are, this device is installed in the building exhaust gas flue, can prevent effectively that smoke blowing from falling cigarette, help home environment, and easy for installation in construction.
