(3) so material is common common material on the market in the utility model, and it is simple in structure, low price, cost is very cheap, has established solid foundation for it promotes the use on a large scale;
(4) the utility model also is provided with a double end bifurcated pipe that closely connects and be communicated with it in described outlet pipe end, and the water that outlet pipe flows out can change water, oil suction operation simultaneously at this pipeline shunt, has improved widely working efficiency;
(5) the utility model is socketed with the internal cover type tube-like interface in described double end bifurcated pipe, and is socketed flexible pipe at this tube-like interface, flexible pipe is translation-angle arbitrarily, has overcome the defective that straight tube in the prior art can't rotation angle;
(6) the utility model is provided with positioning block in the joint of described one-way valve and intake pipe, outlet pipe, and this positioning block is in the intake pipe, and it is in order to preventing one-way valve by water pressure pushing, and causes displacement, to such an extent as to leak gas during the one-way valve open and-shut mode;
