By adopting technique scheme, handle is arranged in the screwed hole on valve rod by bolt, realizes on the one hand connecting, realizes the spacing between handle front end face to locating piece on the other hand, guarantee that handle will not relocate on block to be difficult to rotate even at the cost of one's life, it is possible to according to regulating voluntarily.

Of the present utility model it is further arranged to: described handle includes the sleeve pipe with locating slot and pinches, for hands, the handle held, and described handle is connected on valve rod.

By adopting technique scheme, handle includes the handle being connected in scheme, and longer can the pinching for hands of handle length is held, it is easy to stress, making rotation more laborsaving, handle front end has been wholely set sleeve pipe simultaneously, and the front end face of sleeve pipe is provided with locating slot can with locating piece clamping.

Of the present utility model be further arranged to: described valve body between water inlet pipe and core and core be provided with wear-resisting ring relative to the opposite side of water inlet pipe.

By adopting technique scheme, being provided with wear-resisting ring in core both sides, one plays positioning action, and two play sealing function, prevents liquid communication when valve body is closed.

Of the present utility model it is further arranged to: described core is provided with the through hole that a T-shaped runs through, described core is additionally provided with the mounting groove for valve rod grafting.

By adopting technique scheme, turning handle, during by valve rod transmission, core rotates, it is achieved closure or openness valve body, and core upper end is additionally provided with the mounting groove realizing linkage for valve rod grafting.

Of the present utility model it is further arranged to: described water inlet pipe is connected with valve body screw thread.

By adopting technique scheme, water inlet pipe is connected with valve body screw thread so that core and wear-resisting ring are installed more convenient.

In sum, this utility model has the advantages that and realizes by realizing handle and can rotate continuously in one direction opening and closing valve body, and the pipeline impact connected for valve body compared to existing technology is less；And locating piece can well determine whether core opens and closes thorough, easy to operate.
