Abstract

The utility model discloses a liquid level switch and a liquid storage tank, which relate to the technical field of liquid level valves and comprise a valve body, a floating ball, a connecting rod and a plug, the plug and the floating ball are respectively fixedly connected to two ends of the connecting rod, the connecting rod is connected to the valve body in a sliding mode, a conical first matching surface is arranged on the periphery of the plug, and a second matching surface is arranged on the inner periphery of the valve body. Fluid enters from a liquid inlet at one end of the valve body, which is away from the floating ball, and is discharged from a communication hole on the peripheral wall of the valve body, so that the liquid supply function is realized. The floater floats in the liquid level, and the floater can upwards remove when the liquid level risees, and when first mating surface and second mating surface matched, the end cap can shutoff in the inlet to make the fluid stop supplying, avoid the container in the liquid level too high and lead to spilling over. Still include the jar body, including the feed liquor pipe, the installation section grafting of feed liquor pipe is in the valve body, and the diapire of end cap can press the terminal surface of touching the installation section when the liquid level reduces to the end cap shutoff is in the feed liquor pipe, in order to avoid the fluid in the liquid storage jar to follow the feed liquor pipe backward flow, avoid taking place to leak.
