[0002] The fire damper is used in the air supply and return pipelines of ventilation and air conditioning systems. It is usually open. When a fire occurs and the temperature of the gas in the pipeline rises to 70°C, it will automatically close, and it can meet the fire resistance stability and fire resistance within a certain period of time. Integrity requirements, its smoke and fire resistance; while the valves in the prior art often adopt the form of a single blade, so the strength and stability of the blade are lacking

Abstract

The invention discloses a forming structure and method of a valve blade. The structure of the valve blade is simple, and the valve blade includes an upper blade body and a lower blade body. The upperblade body and the lower blade body have the same structures. A sealing piece is arranged between the upper blade body and the lower blade body. The upper blade body and the lower blade body are overlapped and connected by riveting. The left sides and the right sides of the upper blade body and the lower blade body are symmetrically provided with flanging. Three triangular tendons are arranged between the upper blade body and the lower blade body. A square tendon is arranged between each two adjacent triangular tendons. The forming structure of the valve blade is compact, high in efficiency and good in effect. The forming method of the valve blade is convenient to operate and saving in time and effort.

Description

technical field [0001] The invention relates to the field of valves, in particular to a forming structure of a valve blade and a forming method thereof. Background technique [0002] The fire damper is used in the air supply and return pipelines of ventilation and air conditioning systems. It is usually open. When a fire occurs and the temperature of the gas in the pipeline rises to 70°C, it will automatically close, and it can meet the fire resistance stability and fire resistance within a certain period of time. Integrity requirements, its smoke-proof and fire-blocking effect; while the valves in the prior art often adopt the form of a single blade, so the strength and stability of the blade are lacking. Therefore need to produce a kind of high strength, high stability blade. Contents of the invention [0003] The object of the present invention is to provide a valve blade forming structure and forming method thereof, which have high strength, good stability, compact st...
