That the heating equipment worked more effectively, use various devices and devices. One of such devices is the deflector. How the deflector is arranged? And how to assemble it by own efforts?
The word "deflector" in translation from Latin means "to reject". When designing the deflector effective deviation of exhaust air at ventilation is also its direct assignment. Part of the ventilated air does not leave on dymootvodyashchy channels and remains in the building. That it did not occur, when designing it is necessary to consider the reasons for which air does not leave the ventilated room. It can be:
1. Incorrectly chosen thickness of section of outlet pipe.
2. Wrong location of pipe on roof and its insufficient height. 3. Gusty wind can blow in pipe and cause insufficient draft at which combustion products are not removed completely.
Use the wind-shelter device of the deflector. It is based on the principle of use of wind for suction of gases from ventilation or smoke pipe. The deflector changes the direction of wind in which the movement of gases from ventilating ducts is most favorable. The deflector is also protection against hit in ventilating ducts of garbage, rain or snow.
For wind deviation from the vertical direction on the top and lower parts of the diffuser there have to be ring releases. The weather vane is applied to protection of flue against wind. Over the diffuser mount cone-shaped umbrella. The lower cylinder is made of asbestos or clay pipe. Design of umbrella and the diffuser — from the galvanized sheet of steel. Considering adverse operating conditions of these elements of the device, at their production it is recommended to apply boiler steel, it is more corrosion resistant also to the big range of change of temperature.
For convenience in production it is possible to make cardboard curves in full scale. Thanks to them it is possible to calculate design with bigger accuracy.
Before creating the deflector for outflow of air or flue, it is necessary to make the scheme on which all its sizes will be specified and also to take into consideration parameters of all constituent parts and their ratio among themselves (ratios are visible on photo). To buy necessary materials. Proceeding from the inside diameter of flue, height of the device and width of the diffuser is chosen. During creation of the drawing, it is possible to be guided by the deflector CAGI device. In more detail about it there is the corresponding literature.
If the deflector with large diameter is installed and it is high, then it is necessary to apply guy wires.
1. By means of collars the top cylinder to the lower part.2 fastens. Brackets the cap with the return cone.3 fastens. On the lower glass fix racks with the help of bolts and nuts by the section of M6.4. By means of reducers on pipe of flue the deflector is installed.
