What's the difference between a throttle valve and a check valve? Are they the same?

Answer:

The principle is very simple, just like upstairs said, like a revolving door, this is the swing test. There are lifting type, it is unknown.And "throttling" is to reduce the pressure of the fluid. In the pipeline, the fluid through the throttle valve, through the hand wheel or other transmission way to adjust the size of the internal channel, so that the flow of fluid flow down, to save traffic flow.
The same valve, but the effect is entirely different.The so-called "check back" is to let the fluid in the pipeline can only flow in one direction, can not let it return, so it is also called one-way valve. It works automatically.
The check valve is directional, so it should be clear when installing. It is like a swinging door that opens in one direction or closes on the other. When the liquid flows towards the opening, the door opens, and when it is stopped, the self pressure of the liquid passing through the door closes automatically and acts as a hindrance to the flow of liquid.Throttle is simple, water switch is one of the throttle valve.
