Buoyancy automatic control valve

Abstract

The invention discloses a buoyancy-type automatic control valve which comprises a valve body and a buoyancy-type on / off component, wherein the buoyancy-type on / off component comprises a floater for providing buoyancy, a pressure regulating chamber, a diaphragm-type valve core component, a pressure relieving channel, a seal plug, a linkage element, wherein the pressure regulating chamber is arranged above a control chamber; the diaphragm-type valve core component is arranged in the pressure regulating chamber and is used for separating the water inlet of a water outlet channel and the water outlet of a water inlet channel; the pressure relieving channel is used for communicating the pressure regulating chamber with the external environment; the seal plug is used for sealing and blocking a pressure relieving channel; the linkage element is used for linking the floater and the seal plug; the linkage element comprises a lever, a rotary shaft positioned at one end of the lever and a transmission element arranged at the middle part of the lever; the rotary shaft is arranged on the valve body; the seal plug is arranged on the lever and is positioned between the rotary shaft and the transmission element; and the transmission element drives the lever to rotate along the rotary shaft under the driving of the floater, and further drives the seal plug to perform the action of sealing and blocking the pressure relieving channel or opening the pressure relieving channel. The buoyancy-type automatic control valve provided by the invention is reasonable and compact in structure, has higher flexibility, and is difficult to damage.

Description

technical field [0001] The invention belongs to the technical field of structural design of automatic control valves, and in particular relates to a buoyancy type automatic control valve. Background technique [0002] Common open water storage containers, such as buckets, pots, vats, water towers, and toilet flushers, have a capacity problem when storing water, that is, when water is added to a certain level, the water will overflow , so certain measures are needed to prevent its overflow. For example, in a restaurant, when chefs cook, they use water very frequently, with a time limit, and the amount is relatively large. Their habitual practice is to put an open container under the faucet, and then turn on the tap all the time. Scooping from an open container will result in a large amount of water draining away. For this approach, there is no corresponding product on the market at present. [0003] For toilet water storage tanks, the current common solution is to use buoy...

AI Technical Summary

Problems solved by technology

[0003] For toilet water storage tanks, the current common solution is to use buoyancy-type self-control valves to control the water level, such as common items such as toilet water storage tanks and water towers. The advantages of using buoyancy-type self-control valves to realize automatic quantitative water supply are: The cost is low, but also because of its many parts, complex structure, and high processing precision requirements, it is prone to failure and cannot be used normally
