Simple butterfly valve opening and closing mechanism

Abstract

The invention discloses a simple butterfly valve opening and closing mechanism. An opening and closing mechanism is mounted on a fixing plate and fixedly connected; the outer side of the fixing plateis fixedly connected with a bearing mechanism; the opening and closing mechanism comprises a dished plate and a connecting piece, four sets of the dished plates and the connecting pieces are providedand circumferentially mounted on the fixing plate; each dished plate is hinged to the corresponding connecting piece by a second hinge; each connecting piece is fixedly connected with an outer ring ofthe bearing mechanism; the bearing mechanism comprises an inner ring, balls and the outer ring, the inner ring is fixedly connected with the outer side of the fixing plate, the inner ring and the outer ring are connected by balls in a rotation manner; each dished plate is divided into four pieces, and the movement track of the bearing mechanism to open and close each dished plate is of a semi-circular reciprocating type, so that each dished plate is more convenient and simpler to open and close than a butterfly valve used in common daily life; in the fully open state, no intermediate rotatingrod is needed, so that the water inlet and the air inlet are not affected by the resistance, thereby enabling the flow rate to be smoother, and the mechanism disclosed by the invention is compact instructure, so that the occupied space is small.

Description

technical field [0001] The invention belongs to the technical field of butterfly valve opening and closing mechanism, in particular, the invention relates to a simple butterfly valve opening and closing mechanism. Background technique [0002] At present, the disc plates of the common butterfly valves are all round, and most of the controls for their rotation are rotary switches, and most of the operators are adult men. This situation happens to be women, the elderly and children live more at home. If the rotation occurs and rusts to death, the clenching force of women and children is not large enough, which can easily lead to safety accidents. [0003] Chinese patent application number CN201320312754.1, a new type of multifunctional signal clamp butterfly valve, including opening and closing handle, stop dial, actuator, valve body, valve plate and valve shaft, also includes switch signal indicator light, switch indication The lamp is connected with a signal device, the val...

Problems solved by technology

[0002] At present, the disc plates of the common butterfly valves are all round, and most of the controls for their rotation are rotary switches, and most of the operators are adult men. In this case, there are more women, the elderly and children at home. If the rotation occurs, the grip force of women and children will not be strong enough, which will easily lead to safety accidents.
