Saying the greenhouse effect is like a one-way valve means that while it allows sunlight to enter the Earth's atmosphere and warm the planet, it also traps some of the heat that would normally escape into space, leading to an overall increase in temperature. This is similar to a valve that lets water flow in one direction but restricts it from flowing back, resulting in a buildup of pressure.
