According to Reference.com, a sluice valve is a type of gate that is designed to control the flow of a fluid passing through it. It works by lifting a round or rectangular wedge out of the path of the fluid.Know More
Though they can be used to regulate fluid flows in increments, sluice valves are generally not designed for that purpose and are typically either fully opened or fully closed. The main purpose of a sluice valve is either to completely allow a fluid flow or completely prevent one.
A sluice valve's ability to cut through liquids makes it a useful valve configuration in the petroleum industry.Learn More
An unloader valve works by diverting water flow into a bypass as soon as a trigger gun valve is closed. These two valves work together to create a unique system that directs water into a float tank or a pump inlet. Unloader valves are used to circulate water into the inlet side of a pump, while trigger gun valves control the flow of water.Full Answer >
A thermal expansion valve in refrigeration or air conditioning systems uses a temperature sensing bulb to open a valve, allowing liquefied refrigerant to move from the high pressure side of the system to the low pressure side before entering the evaporator. As the evaporator temperature decreases, pressure on the bulb decreases, allowing a spring to close the valve, according to Reference.com.Full Answer >
A check valve , also called a non-return valve, is a mechanical device that normally allows fluid to flow through it in only one direction. The force of upstream fluid creates high differential pressure across the interior valve body, and it then allows forward streams to pass through.Full Answer >
Remove the tank lid and perform a visual inspection of the toilet flush valve to start addressing any issues or problems the toilet may be having. Adjust the flapper or tension chain to ensure the flush valve is able to form an effective seal. Drain the toilet tank and replace the flush valve to address a leaking flush valve.Full Answer >
