Problems solved by technology

[0002] With the rapid development of the construction industry, building fire prevention and smoke exhaust systems are widely used in construction projects, and issues related to fire safety, energy conservation and environmental protection are becoming more and more prominent. High requirements, the general fire and smoke exhaust valve is welded after molding, the joint between the actuator drive shaft and the fire and smoke exhaust valve blade is prone to seizure and rust, which affects the structural strength of the entire fire and smoke exhaust valve, and the operation In addition, during production, in addition to the problem of good flatness of the iron plate after forming process, there is also the problem of thermal deformation due to welding process, which brings great processing to the workers who make the product. Difficulty, and the amount of air leakage does not meet the requirements of national standards

Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is further described;

[0019] In the accompanying drawings, a round valve includes a circular outer frame 1, an actuator 2 and blades 3, a tension spring 101 is connected between the circular outer frame 1 and the blades 3, and the circular outer frame The transverse section of 1 is "◎" shape, the purpose is to facilitate the processing and manufacturing, reduce the welding process, and have higher structural strength. The circular outer frame 1 is provided with an intermediate bracket 4 and a boss 102. The circular The connection between the outer frame 1 and the boss 102 is a riveting connection, and the connection with the intermediate support 4 is also a riveting connection. The purpose is to reduce the welding process and prevent thermal deformation. The intermediate support 4 and the A first seal 103 is provided between the circular outer frame 1, a second seal 104 is provided on the blade 3, a...

Abstract

A round valve comprises a round outer frame, an execution mechanism and blades. Tension springs are connected between the round outer frame and the blades; the transverse section of the round outer frame is in a double-circle shape, wherein the small circle in the two circles is sleeved with the large circle in the two circles, and a middle support and a boss are arranged on the round outer frame; first seals are arranged between the middle support and the round outer frame, and the blades are provided with second seals and are connected with the middle support through transmission shafts; brass bushes are arranged at the connecting positions of the transmission shafts and the middle support; the execution mechanism is connected to the round outer frame through the boss and is connected with the transmission shafts; linkage rods are arranged on the transmission shafts, and the longitudinal section of each transmission shaft is in a square shape; the longitudinal section of each connecting position of each blade and the corresponding transmission shaft is in a square shape; and scuffing and rusting cannot appear, machining is convenient, and the air leakage amount also reaches the standard requirement.
