Abstract

The utility model provides a residential smoke lead-flow check valve that has a check function and enables the smoke in a flue flowing from up to down and consistent with an air flow direction in the flue, which is conducive to discharge the smoke and form negative pressure at other check valves and more effectively to prevent adverse current. Meanwhile, in any situation of opening or closes, the valve reliably dissembles the valve module, which comprises a shell and a valve. The utility model is characterized in that a bottom of a valve 3 is connected with a counterpoise 4 through a valve rotor axis 6 and a lead-flow plate 5 is fastened on the top of a flue pipe 10 through a shell 1.

Description

Dwelling house flue gas flow-guiding type check (non-return) valve

The utility model relates to a kind of house kitchen, toilet discharged flue gas of making and flows into the check (non-return) valve that flue also can effectively be discharged flue gas, be prevented adverse current by predetermined angular.

For improving the dwelling house living environment, press the regulation of code of building design, newly-built dwelling house is " kitchen and the nothing directly toilet of ventilation should be provided with centralized, as to prevent adverse current, anti-smoke blowing smoke evacuation, blow-out shaft; must not discharge flue gas to common part ", at present, the dwelling house fume emission has pressure swing type and common check (non-return) valve formula flue system.The pressure swing type flue utilizes the different blast of primary and secondary flue to play non-return effect according to aerodynamic transformation principle, but its exist complex structure, volume big, can not change problems such as smoke inlet position, very flexible; The valve of common check (non-return) valve is opened from bottom to top by stream pressure and gravity, air-flow is subjected to the downward inflow flue of placing restrictions on of valve, and is just in time opposite with from bottom to top air current flow direction in the flue, makes flue bottom air pressure bigger than top, increased air drag, after valve is contaminated by smoke simultaneously, can't close tightly, cause smoke spillage, though the detached type check (non-return) valve is arranged at present, valve member can be pulled down cleaning, but valve closing is when not in place, valve member can block and can't take off.

The purpose of this utility model provides a kind of dwelling house flue gas flow-guiding type check (non-return) valve, and it not only has non-return function, and the flue gas that enters flue is flowed from bottom to top, consistent with airflow direction in the flue, favourable discharging flue gas, and in other check (non-return) valve place formation negative pressure, more effective adverse current that prevents.Valve can both shirk valve member reliably at any state of opening or closing simultaneously.

The purpose of this utility model can reach by following measure:

A kind of dwelling house flue gas flow-guiding type check (non-return) valve comprises shell, valve, it is characterized in that valve 3 lower ends are connected with balance weight 4 by valve hinges 6, and deflector 5 is fixed on the flue tube 10 by shell 1.

The purpose of this utility model can also reach by following measure:

Deflector 5 is 0 °～80 ° angles with the vertical direction of flue tube 10.

Advantage of the present utility model:

Owing to adopt such scheme, can make that house smokejack volume is little, simple in structure, easy for installation, the smoke evacuation entry position flexibly, fast, the no adverse current of fume emission speed, shirk and advantage such as clean conveniently.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model structural representation.

1. shells, 2. valve members, 3. valves, 4. balance weights, 5. deflectors, 6. valve hinges, 7. construction bolts, 8. mounting plates, 9. catchment cups, 10. flue tubes among the figure

Press the accompanying drawing structure, check (non-return) valve is by construction bolt 7 and mounting plate 8 and flue tube 10 installation in position.The pipeline of fume extractor links to each other with check (non-return) valve shell 1, flue gas is after direction only enters check (non-return) valve by force as shown, valve 3 relies on the gas pressure effect, open from top to bottom around valve hinges 6, flue gas is through behind the deflector 5, make flue gas upwards flow into flue tube 10 fast, and the gas that drives in the flue upwards flows fast, form negative pressure in the flue bottom with 45 ° angle.When flue gas flows fast upwards, during by a last deflector 5,, the flue effective aperture produces transformation because of changing, also form relative negative pressure at non-return valve port.When flue gas did not enter, valve 3 and balance weight 4 were closed around valve hinges 6 automatically by the gravity effect of self, the centre-of gravity shift maximum of valve 3 and balance weight 4, and it is tighter that valve 3 and valve member 2 are closed, and prevents adverse current.When needs clean, valve member 2 is spurred downwards, valve 3 as in opening, under the effect of shell 1, positive closing is conveniently shirked, and never blocks.

Claims
