Abstract

The utility model discloses an airtight valve body, which comprises a framework, blades and seal strips, wherein the blades are mounted inside the framework, the seal strips are fixedly mounted on the blades, and the seal strips are elastic and metallic and fixed on the blades in a riveting manner. The airtight valve body relates to an improvement to the seal strips of a conventional fireproof exhaust smoke valve, improves the fireproof performance and the leakproofness of the valve body, has the advantages of high-temperature resistance, corrosion resistance, low leakage and simple structure, and can be extensively applied to the field of fireproofing exhaust smoke valves.

Description

A kind of airtight valve body

Technical field

The utility model relates to a kind of airtight valve body, the valve body of particularly a kind of fire-closing valve for building, exhaust smoke valve.

Background technique

At present, fire-closing valve for building, exhaust smoke valve exist between blade and the blade the big shortcoming in gap between poorly sealed and blade and the valve body housing, and the Stamping Steel Ribbon of existing fire-closing valve, exhaust smoke valve generally adopts rubber or plastics to cause as sealing material under the high temperature condition or lose the phenomenon of sealability after aging, so existing building can only satisfy normal temperature with the leaking out of fire-closing valve, exhaust smoke valve (cigarette) amount or to high temperature resistant less demanding environment, and can't satisfy present tall building, underground railway and high airtight requirement high-grade civilian, commercial building.

Summary of the invention

In order to solve the above-mentioned shortcoming of existing fire-closing valve, exhaust smoke valve, the utility model provides a kind of simple in structure and airtight valve body with high leak tightness.

The technological scheme that the invention for solving the technical problem adopted is: a kind of airtight valve body, comprise framework, blade and Stamping Steel Ribbon, wherein said blade installation is in framework, described Stamping Steel Ribbon is fixedly mounted on the described blade, and Stamping Steel Ribbon is the elastic metallic Stamping Steel Ribbon and is fixed on blade by the riveted joint mode.

As improvement of the technical scheme, described Stamping Steel Ribbon is " L " shape elastic sheet metal.

Another kind as technique scheme improves, and the upper inner of described framework and lower inside are provided with the curved metal Stamping Steel Ribbon.

The beneficial effects of the utility model are: to existing valve body, particularly the Stamping Steel Ribbon of fire-closing valve, exhaust smoke valve improves, improved between the blade and blade and valve body housing between fire retardancy and seal, have high temperature resistant, corrosion-resistant, lowly reveal, advantage of simple structure.

Embodiment

Figure 1 shows that a kind of airtight valve body that the utility model provides, comprise framework 1, blade 2 and Stamping Steel Ribbon 3, wherein said blade 2 is installed in the framework 1, and described Stamping Steel Ribbon 3 is fixedly mounted on the described blade 2, and described Stamping Steel Ribbon 3 is the elastic metallic Stamping Steel Ribbon.Described blade 2 links to each other with lower inside with the upper inner of framework 1 and can rotate, the both sides of blade 2 are equipped with by the fixing elastic metallic Stamping Steel Ribbon 3 of riveted joint mode, as optimal way, what the utility model adopted is " L " shown in Figure 5 type elastic sheet metal is fixed on blade 2 by no rivet mode both sides.

Fig. 2 is the side view of airtight valve body shown in Figure 1, and wherein the upper inner of framework 1 and lower inside are provided with Stamping Steel Ribbon 4, and described Stamping Steel Ribbon 4 is the metallic seal bar, and as optimal way, the utility model adopts curved metal Stamping Steel Ribbon shown in Figure 6.

Fig. 3, the 4th, the working state schematic representation of the blade 2 of airtight valve body shown in Figure 1, when described blade 2 when full open state shown in Figure 3 forwards complete closure state shown in Figure 4 to, thereby the hard-wired elastic metallic Stamping Steel Ribbon 3 in blade 2 both sides is close to the adjacent effect of sealing fully that formed, because adopted fire-resistant, etch-proof elastic metallic material, it is high temperature resistant to make Stamping Steel Ribbon have, ageing-resistant corrosion and high strength can satisfy present tall building fully, underground railway and high-grade civilian, commercial building is to the high temperature resistant and high airtight requirement of fire and smoke exhaust valve.

Certainly, above-mentioned is preferred implementation of the present utility model, and not limiting becomes protection domain of the present utility model, except above-mentioned mode of execution, so long as the identical airtight valve body of basic structure all belongs to protection domain of the present utility model.
