Air valve having fireproofing function

Abstract

The invention discloses an air valve having the fireproofing function. The air valve comprises an air valve body (10). The air valve is characterized in that a fire-proof layer which covers the whole outer surface of the air valve body is composited onto the outer surface of the air valve body; the fire-proof layer and the air valve body are closely combined into a whole; and the fire-proof layer comprises a layer of anti-rust paint (21) and one or more layers of fire-proof coatings (22), wherein the anti-rust paint (21) is composited onto the outer surface of the air valve body, and the one or more layers of fire-proof coatings (22) are composited onto the surface of the anti-rust paint. The fire-proof coatings are fire-proof coatings for steel structures. According to the air valve having the fireproofing function, the fire-proof layer is arranged on the outer surface of the air valve body, and the fire-proof layer and the air valve body are combined into a whole so that the air valve can be directly mounted and used due to the fact that the air valve has fireproofing performance, and therefore a large number of spaces and occupied areas can be saved; and the air valve is stable and reliable in fire resistance, low in cost and good in aesthetic performance.

Description

technical field [0001] The invention relates to a damper, in particular to a damper with a fireproof function provided with a fireproof protective layer. Background technique [0002] The smoke prevention and exhaust system for fire fighting is widely used in office buildings, hotels, restaurants, theaters, shopping malls, hospitals, underground parking lots and other places that require smoke prevention and exhaust. Existing fans, air ducts, air valves, etc. used for smoke prevention and exhaust are mostly made of steel plates or galvanized steel plates, and such devices themselves have not been treated for fire protection, so they do not have fire protection functions. A large number of scientific research data and fire cases at home and abroad show that air ducts, fans, dampers, etc. without fire protection are at risk of collapse, deformation, and destruction during a fire, and damage to equipment will lead to fire and smoke spread . Therefore, under normal circumstanc...

Problems solved by technology

Although this method can play a role in fire prevention, because the closed space constructed by this method not only occupies a certain space on the construction site, but also can only be carried out on-site construction when the damper is installed, and the treatment of the interface is difficult to guarantee, resulting in Construction is difficult and expensive

In addition, the fixed size and extremely poor plasticity of the air valve make the construction difficult, and the material and labor costs are high

Another method currently used is to wrap it with soft fire-resistant cotton felt. Although this method can be installed on the surface of the equipment, the installation is more convenient and the fire-resistant performance is better, but the use of qualified fire-resistant cotton felt will increase the installation cost, and Difficult to cover all irregular corners

In addition, more users simply ignore the relevant regulations and install them directly, thus burying potential safety hazards.
