What is the function of an automatic valve triggered

Subject : Engineering

Question: What is the function of an automatic valve triggered by a hollow float at the end of a lever in a fluid system?

A) To control the flow of electricity

B) To regulate fluid levels by opening or closing the valve based on the liquid’s height

C) To measure the pressure within a pipe

D) To detect gas leaks in a system

Expert Verified Solution:

The function of an automatic valve triggered by a hollow float at the end of a lever in a fluid system is:

B) To regulate fluid levels by opening or closing the valve based on the liquid’s height

Explanation:

An automatic valve with a hollow float is typically used in fluid systems, such as water tanks or reservoirs, to maintain a desired liquid level. The float rises and falls with the liquid level. When the liquid reaches a certain height, the float triggers the valve to either open or close:

If the liquid level is too high, the float will rise, causing the valve to close and stop the flow of additional liquid.

If the liquid level is too low, the float will fall, causing the valve to open and allow more liquid to enter the tank.

This mechanism helps to automatically regulate and maintain the desired level of fluid within the system. The other options (A, C, D) do not describe the function of a float valve in a fluid system.
