<p>A superhigh pressure micro-torque leakage-free valve includes a valve body (1), a valve stem (3), a valve plate (2) and a handle (13). A fluid storage chamber (9) is provided within the valve body and a slide (8) provided within the fluid storage chamber is connected to the valve body by a connector. An oil channel (7) is provided on the lower part of the valve body, and a check valve is provided in the oil channel. A rotary limiting nut (14) is provided between the valve body and the valve plate, and is connected to the valve plate. The valve stem passes through the rotary limiting nut and the valve plate, and is provided with a valve stem thread (15) which is screwed on an inner thread (19) of the rotary limiting nut. The valve stem thread is screwed to the upper limit of the inner thread of the rotary limiting nut in an opening state of the valve and the valve stem thread is screwed to the lower limit of the rotary limiting nut in a closing state of the valve. A gap (1-1) is formed above the inner thread of the rotary limiting nut. The valve saves labor when opening and has high tightness.</p> |
