About Self lock valve(Autolock valve):

 

   The self lock valve is a new type float valve, there is a control hole on the float valve besides the outlet hole, so there is two hole of the self lock valve to control the water flow. The function of control hole is to control the flow of water , then make the pressure to the seals rubber of the outlet hole , finally the valve been closed by the water pressure. The advantage of this valve is that the control hole only control the flow of water, not close the water, so the control hole is very small. but the outlet seals hole is very big, so the self lock valve have a big flow rate than the strong lock valve.
