How Pilot Lights Work | HowStuffWorks

If the pilot light flame were to ever blow out, the gas would keep coming out of the pilot light tube. If this gas were to collect inside your house and then ignite, it would create an explosion. To solve this problem, the pilot light tube has a valve that cuts the gas to the pilot light in the event that it ever blows out.
