VALVE USING MOVING LOAD
Document Type and Number:
WIPO Patent Application WO/2021/141177
Kind Code:
A1
Abstract:
The present invention relates to a valve using a moving load and, more specifically, to a valve comprising: a valve body having entrances at opposite sides facing each other, an internal passage formed therein such that a fluid can flow therein, opposite wall surfaces at the entrance sides, which are formed to be inclined in the direction toward the center portion of the internal passage, and through-holes respectively formed in the wall surfaces; opening/closing units which are supported by the wall surfaces while contacting the wall surfaces so as to partition the internal passage, and which rotate to respectively open/close the through holes; and a roller member which moves to a lower place due to the inclination of the valve body and presses interworking units of the opening/closing units to open/close the through-holes at the opposite sides. The opening/closing units include opening/closing devices which are elongated at the opposite sides in the lengthwise direction of the valve body and which each have, in a center portion, an elliptical hole, at the entrance side, to be fastened with a rotary shaft which is a hook corresponding to the elliptical hole and formed in the valve body, so as to act as latch devices, and on the latch device, a high load portion blocks the through-hole due to the weight thereof, and a low load portion is pushed by the moving roller member to allow the high load portion to rotate due to the principle of leverage.
