Liquid flux quantitative control device

Abstract

The invention relates to a liquid flux quantitative control device. The device mainly includes a quantitative mechanism and an early-warning positioning control mechanism; the quantitative mechanism is mainly composed of a positioning shaft, a quantitative spring, a shaft gear, a combined ratchet wheel and a plurality of gears, wherein the combined ratchet wheel is composed of one-way internal and external gears and a ratchet wheel which is fixed on the gears; the early-warning positioning control mechanism is mainly composed of a compression bar, a return spring, a big closure plate, a small closure plate and a positioning wheel; in the quantitative mechanism, the positioning shaft is fixed on the shaft gear, and is connected with the quantitative spring, the shaft gear is connected with the combined ratchet wheel, and the gears in the combined ratchet wheel are connected with, and drive other gears; in the early-warning positioning control mechanism, the positioning wheel is fixed on the positioning shaft of the quantitative mechanism, and is provided with a positioning notch, the return spring is arranged under the compression bar, the compression bar is connected with the big closure plate, the big closure plate is coaxially connected with the small closure plate, a hole is disposed on the big closure plate, locator cards are arranged on the big closure plate and the small closure plate, and the geometric shape of each locator card is matched with the positioning notch of the positioning wheel. When the big closure plate is closed, the hole thereon can allow a certain flow, if a user finds the obvious decrease in flow, a tip is obtained to show that the device is about to closed, thereby realizing the early-warning function.
