Further, described flap cover is antiseptic rubber cover;
Further, the screw rod bottom that compresses of described rotation and lifting hand lever lower end is pressed on filler cover plate 114 surface;
Further, the center of the central axis of the central axis of described valve seat, flap, the central axis of displacement of valve rod positioning block, the central axis of valve rod and stop valve import is on same straight line.
The top of valve gap of the present utility model is provided with two rotation and lifting hand levers, when control rotation hand lever screws and rotation and lifting hand lever is declined, the screw top that compresses of rotation and lifting hand lever presses filler coverslip surface, make filler tightr, be provided with two-layer sealing gasket simultaneously, substantially increase the sealing of stop valve, prevent medium from overflowing, cause waste, even corrode check-valve piece, improve the quality of product of stop valve, installed displacement of valve rod positioning block additional simultaneously, can effectively avoid stop valve in unlatching, during closing operation, the possibility of inner member generation lateral displacement, thus reduce the situation that wearing and tearing occur check-valve piece, improve usability and the working life of product, flap external sheath flap cover, flap cover is antiseptic rubber cover, not only increase antiseptic property, the cutoff performance of Angle Stop valves have also been obtained reinforcement simultaneously.
When Angle Stop valves is except cut-off state, not only stop valve import is by valve flap seals, and stop valve outlet simultaneously is also intercepted by displacement of valve rod positioning block, improves the cutoff performance of Angle Stop valves.
The beneficial effects of the utility model are:
The utility model simplicity of design, rational in infrastructure, the design of rotation and lifting hand lever and double-layer seal pad, greatly strengthen the sealing of Angle Stop valves, prevent medium from overflowing, cause waste, even corrode check-valve piece, improve the quality of product of stop valve, the displacement of valve rod positioning block installed additional, the situation that wearing and tearing occur check-valve piece can be effectively reduced, improve usability and the working life of Angle Stop valves, and the use of flap cover, not only strengthen the cutoff performance of stop valve, and change also very convenient, simultaneously flap closing and obstruct that displacement of valve rod positioning block exports stop valve stop valve import, also the cutoff performance of Angle Stop valves is strengthened.
