Problems solved by technology

[0002] The pipelines for infusion or gas delivery are generally circular, so circular valves are used in a wider range, but the circular valves in the prior art only include one control blade or two control blades, and the resistance when opening or closing is relatively large. Large, laborious operation, and the stress at the joint between the shaft and the blade is relatively large, resulting in a short service life of the blade, and the opening degree of the valve cannot be accurately controlled, which is inconvenient to use

Abstract

The invention discloses a multi-blade type round valve. The multi-blade type round valve comprises a shell, blade assemblies and a hand wheel assembly. The multi-blade type round valve further comprises rotation arms and connection arms. The shell comprises a connecting cylinder, a center connecting block, three fixing rods and a support. The center connecting block is arranged in the center of the connecting cylinder and fixedly connected with the connecting cylinder through the fixing rods. The support is fixedly connected with the connecting cylinder. First connecting holes are evenly formed in the connecting cylinder, and second connecting holes are evenly formed in the center connecting block. Each blade assembly comprises a sector blade, a first rotating shaft and a second rotating shaft. The multi-blade type round valve has the beneficial effects that the multiple sector blades are arranged, the opening resistance is small, the service life of the blades is long, and labor is saved during operation; and the opening degree of the valve can be better accurately controlled, and using is convenient.

Description

technical field [0001] The invention relates to a valve, more precisely a multi-blade circular valve. Background technique [0002] The pipelines for infusion or gas delivery are generally circular, so circular valves are used in a wider range, but the circular valves in the prior art only include one control blade or two control blades, and the resistance when opening or closing is relatively large. Large, laborious operation, and the stress at the joint between the shaft and the blade is relatively large, resulting in a short service life of the blade, and the opening degree of the valve cannot be accurately controlled, which is inconvenient to use. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, so as to provide a blade with multiple fan shapes, which has small opening resistance, long service life of the blade, labor-saving operation, and is beneficial to accurately control the opening degree of t...
