Abstract
A self-operated rainproof hood used for a smoke gas flue belongs to the technology of civil construction; a guide cylinder body is inserted in a central through hole of the smoke gas flue and a base plate, the upper side part of the guide cylinder body is positioned at the upper part of the base plate and is in oblique regular cone shape on the whole, and the peripheral walls of the upper side and the lower side of a rainproof cylinder body are respectively provided with an upper through hole and a lower through hole; the rainproof hood greatly enhances the negative-pressure suction force in the smoke gas flue, and has the characteristics of being simple in structure, low in manufacturing cost, high in exhaust efficiency, good in rainproof effect and reliable in use.
Description
Technical field
The utility model belongs to building building technology, relates generally to the equipped rain-proof structure that uses on the building gas flue.
Background technology
For guaranteeing interchange of air and discharging in the rooms of buildings, in multilayer and high-rise building body of wall, exhaust gases passes is set all.In order to stop that effectively rainwater enters in the exhaust gases passes, keep the cleaning of exhaust gases passes, and eliminate the air-resistance phenomenon that produces because of moist, in recent years, majority all has been equipped with rainproof blast cap on the top ends of exhaust gases passes, has avoided rainwater to enter in the gas flue effectively.But because the defective in the existing rainproof cap structure design makes gas flue top negative-pressure sucking reduce, indoor exhaust efficient and exhaust effect descend.
Summary of the invention
The purpose of this utility model is exactly the problem that exists on the above-mentioned existing rainproof cap structure, design provides a kind of gas flue rainproof blast cap of self-operated type of new construction, when stopping that effectively rainwater enters gas flue, also the negative-pressure sucking at position, gas flue top be to guarantee and improve, exhaust efficiency height, the measured purpose of matter reached.
Basic design of the present utility model is, install the bed plate that has central through hole by expansion bolt in the gas flue upper end, above bed plate, dispose upper cover plate, by the connector group with upper cover plate and bed plate is affixed is integral, the equipped cylindrical shell that keeps off the rain between upper cover plate and bed plate, fixedly stream guiding barrel is installed in inserting in the central through hole of gas flue and bed plate, the upper lateral part of this stream guiding barrel is positioned at bed plate top, and the upper lateral part integral body of stream guiding barrel is inclined-plane right circular cone shape, in the upper and lower side periphery wall of the upside peripheral wall part portion of the cylindrical shell that keeps off the rain, be respectively equipped with through hole and lower through-hole, so far constitute the gas flue rainproof blast cap of self-operated type.
The utility model has increased substantially the negative-pressure sucking in the gas flue in rainproof blast cap, gas flow is smooth and easy, and it is all good with exhaust effect to keep off the rain, have simple in structure, cheap, exhaust efficiency is high, it is effective to keep off the rain, the service-strong characteristics.
Description of drawings
Fig. 1 is the gas flue rainproof blast cap general structure of a self-operated type schematic diagram;
Fig. 2 is the side direction view of Fig. 1.
Piece number explanation among the figure:
1, upper cover plate, 2, connector group, 3, stream guiding barrel, 4, expansion bolt, 5, bed plate, 6, lower through-hole, 7, the cylindrical shell that keeps off the rain, 8, last through hole, 9, gas flue, 10, central through hole.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of gas flue rainproof blast cap of self-operated type, install the bed plate 5 that has central through hole 10 by expansion bolt 4 in gas flue 9 upper ends, configuration upper cover plate 1 above bed plate 5, by connector group 2 with upper cover plate 1 and bed plate 5 affixed being integral, the equipped cylindrical shell 7 that keeps off the rain between upper cover plate 1 and bed plate 5, fixedly stream guiding barrel 3 is installed in inserting in the central through hole 10 of gas flue 9 and bed plate 5, the upper lateral part of this stream guiding barrel 3 is positioned at bed plate 5 tops, and the upper lateral part integral body of stream guiding barrel 3 is inclined-plane right circular cone shape, is respectively equipped with through hole 8 and lower through-hole 6 in the upper and lower side periphery wall of the upside peripheral wall part portion of the cylindrical shell 7 that keeps off the rain.
When operation is used, according to aerodynamic principle, utilize stream guiding barrel 3 upper lateral part positive cones dignity and the slit that constitutes between cylindrical shell 7 internal faces of keeping off the rain to improve the characteristic of wind speed generation kinetic energy, atmospheric gas is entered in the self-operated type blast cap from lower through-hole 6, change wind direction through stream guiding barrel 3 positive cones dignity, discharge the self-operated type blast cap from last through hole 8, the gas fast rise that the negative-pressure sucking that forms in this process drives in the gas flue 9 flows, improve in the gas flue 9 from pull out force, form the negative pressure situation in the gas flue 9, help gas and discharge, and, promoted exhaust efficiency and quality for the flue gas discharge creates good conditions.Keep off the rain cylindrical shell 7 and upper cover plate 1 stopped that effectively rainwater enters in the gas flue 9, keeps the clean state in the gas flue 9, eliminates the air-resistance phenomenon that produces because of moist.
