In the utility model structure, epimere up-down screw thread cooperates with lifting nut, realizes controlling the up-down of screw rod; Because thread rotary orientation is opposite; Open and close nut and do and control identical the moving of screw rod up-down direction, and the moving total that opens and closes nut is the stack of controlling screw rod up-down amount and opening and closing nut self amount of movement, thereby make the plug travelling speed quickening that opens and closes on the nut; Open and close the intake-outlet of water valve body fast, realize the goal of the invention of the utility model.

Said plug has only mobile to the opening and closing action of intake-outlet, and does not have rotation, has avoided the friction of plug to damage, and has prolonged the working life of plug.

Said plug periphery is provided with the sealing flap; The sealing flap is pressed on the end face of water valve body intake-outlet through the moulding cover; Said moulding cover with control screw coaxial and be located in the water valve body, said sealing flap will be controlled screw rod and completely cut off with water and leave, and solve water from controlling the screw flight leakage problem.

Compressing through gland of said moulding cover realizes that said gland screw-thread fit is on water valve body, and said gland is pressed in moulding and puts.

Said lifting nut can be fixedly arranged in the moulding cover, and said switching nut axially (is controlled the axial of screw rod) and is snug fit in moulding overlaps through (opening and closing between nut and the moulding cover) guiding secondary (mechanism).Draw runner and the chute of said guiding secondary (mechanism) for cooperatively interacting.

According to traditional use habit, said epimere up-down screw thread is made as the dextrorotation screw thread, promptly control clockwise rotating of screw rod to closing water tap.

In the conventional design, go up and down the diameter of thread that screw thread and hypomere open and close screw thread of epimere is designed to identical, pitch and also is designed to identically, promptly the opening and closing speed of the utility model can double.

The said screw rod of controlling is equipped with the handle of being convenient to operate in the outer end of water valve body.

The advantage of the utility model:

Compare with the conventional helical water tap; The speed of the opening and closing water tap of the utility model high-speed screw water tap can double at least; In the stage of designing and producing, the suitable intake-outlet sectional area and the appropriate location of plug are set, make handle when rotation 90 is spent, reach standard-sized sheet and full cut-off effect; Can reach ceramics fully and change up the using effect of closing water tap soon; Overcome ceramics change up soon close water tap can not be manually the vertical defective of control, change up soon than ceramics but that to close the water tap cost low, Applicable scope is wider.
