Description

Novel fire prevention valve

Technical Field

The utility model relates to a fire control ventilation equipment technical field, concretely relates to novel fire prevention valve.

Background

The existing fire-proof valve frame body mostly adopts a multi-section frame structure, and the multi-section frame is combined into the fire-proof valve frame body through welding or riveting. The components such as the angle code, the rotating shaft, the blade, the actuating mechanism, the temperature sensor and the like are fixed with the frame body to assemble a fire damper product. For example, chinese utility model publication No. CN208058059U discloses a "new fire damper", in which a frame body is composed of a plurality of members such as a top frame, a bottom frame, and two side frames. This utility model uses the multistage frame to make up into the framework, causes spare part too much, and production processes is complicated, causes batch production cost height, inefficiency.

SUMMERY OF THE UTILITY MODEL

The fire-proof valve frame aims at solving the problems that the existing fire-proof valve frame has more parts, complex production process and low production efficiency. The utility model provides a novel fire prevention valve, a novel fire prevention valve's framework adopts four the same outer frame parts equipment to use angle sign indicating number riveting fixed, the process is simple, and the part is less, environmental protection and energy saving, and production efficiency is high, and is with low costs.

The utility model provides a technical scheme that its problem adopted is: a novel fire damper comprises a frame body, a plurality of rotating shafts, a plurality of blades, an actuating mechanism, a temperature sensor and a stainless steel elastic sheet assembly, wherein the fire damper is required to achieve certain sealing performance when closed. The frame body adopts four same outer frame parts, and two adjacent outer frame parts are fixed by screws and are riveted and fixed by corner connectors to form a square frame body. Wherein, each blade is fixed on the rotating shaft, and each rotating shaft is linked to achieve the purpose of opening or closing. When the fusible metal of the temperature sensor reaches the set temperature, the fusible metal is melted and disconnected, the actuating mechanism is started to drive each blade to be opened or closed, and the fire fighting effects of opening smoke discharge and closing smoke prevention are achieved when fire breaks out. The stainless steel elastic piece assembly is riveted with the edge of the blade and arranged in parallel with the blade, and the sealing performance of the fire damper when the fire damper is closed is improved.

The frame body is formed by connecting and combining four same outer frame components end to end into a square shape.

The frame body is fixed through the screws and is fixed through riveting by using the corner connectors.

In the novel fire damper, one end of the outer frame part is a long U-shaped first flanging which is provided with a through hole for fixing by a screw; the other end is two short U-shaped second turn-ups. And two sides of the outer frame part are L-shaped third flanges for riveting corner connectors and improving the frame strength of the frame body.

The novel fire damper is characterized in that the stainless steel elastic sheet component 7 is fixed on the edge of the blade 5 by riveting technology, and is firm and not easy to fall off.

The beneficial effects of the utility model are that, the utility model relates to a novel fire prevention valve framework adopts general outer frame part to assemble, simple process, and production efficiency is high, and is with low costs. The outer frame component and the stainless steel elastic sheet component are reinforced by riveting, a welding process is not used, a zinc layer is not damaged, paint spraying treatment is not needed, and the stainless steel elastic sheet component is environment-friendly and energy-saving. The first flanging, the second flanging and the angle code flanging of the outer frame component are in a shape like a Chinese character 'pin', are mutually overlapped, reduce the gap of the overlapping part of the frame body, greatly improve the sealing performance of the fire damper and greatly improve the quality.

Detailed Description

The utility model discloses as shown in fig. 1-3, a novel fire prevention valve, include: the temperature sensor comprises an outer frame component 11, a plurality of corner connectors 2, a temperature sensor 3, a plurality of rotating shafts 4, a plurality of blades 5, a plurality of stainless steel elastic sheet assemblies 7, an actuating mechanism 6 and two supports 8. The four outer frame parts 11 are fixed together through screws, the right-angled positions of the two adjacent outer frame parts 11 are riveted through the corner connectors 2 for riveting reinforcement, the frame body 1 is formed by combining, and the support 8 is riveted and fixed on the inner side of the frame body 1. One end of the rotating shaft 4 is fixed in the rotating groove of the blade 5, and the rotating shaft and the blade are not capable of rotating or sliding.
