Abstract
The utility model discloses a hyper-pressure micro-torque non-leakage valve, including a valve body, a valve stem, a valve plate and a handle, wherein a fluid storage room is arranged inside the valve body and a slider is arranged inside the fluid storage room. The valve plate and the slider are connected through connectors. A rotating limit nut between the valve body and the valve plate is connected with the valve plate. The valve stem goes through the rotating limit nut and the valve plate. The bottom of the valve is equipped with an oil passage, and the oil passage is equipped with a one-way valve. Stem threads are arranged on the valve stem and internal threads are arranged on the rotating limit nut. The valve stem thread screws the internal thread of the rotating limit nut. On the condition of the valve opening, the valve stem thread screws to the upper limit of the rotating limit nut; on the condition of the valve close shut, the valve stem thread screws to the lower limit of the rotating limit nut. A gap is left above the internal thread of the limit nut. The utility model is practical and novel, and is characterized by less effort in opening and good tightness.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model comprises valve body 1, valve rod 3, valve plate 2 and handle 13.Be provided with in the valve body 1 in fluid storeroom 9, the fluid storeroom 9 and be provided with ring-type slide block 8.Valve plate 2 and ring-type slide block 8 are connected by link.Be provided with rotary spacing nut 14 between valve body 1 and the valve plate 2, rotary spacing nut 14 is connected with valve plate 2.Valve rod 3 passes rotary spacing nut 14 and valve plate 2.Valve body 1 bottom is provided with oil duct 7, is provided with one-way valve in the oil duct 7.Valve rod 3 is provided with threaded stem 15, and rotary spacing nut 14 is provided with internal thread 19.Threaded stem 15 is threaded onto on rotary spacing nut 14 internal threads 19.Under the valve opening state, threaded stem 15 is threaded to rotary spacing nut 14 internal threads 19 upper limits, and space 1-2 is left in valve rod 3 lower ends, makes one-way valve open-minded.Under the valve closing state, threaded stem 15 is threaded to rotary spacing nut 14 internal threads 19 lower limits, and space 1-1 is left on stop nut 14 internal threads 19 tops.
Described one-way valve is made of valve rod 3, steel ball 6 and oil duct 7.Valve rod 3 lower ends peak on the steel ball 6, and steel ball 6 is positioned at oil duct 7.Described valve plate 2 two ends are provided with rotary head 17 and following rotary head 18.Link comprises Upper shaft sleeve 10, Upper shaft sleeve seat 11, Lower shaft sleeve 5 and lower shaft block set 4.Be separately installed with Upper shaft sleeve 10 and Lower shaft sleeve 5 in last rotary head 17 and the following rotary head 18, Upper shaft sleeve 10 and Lower shaft sleeve 5 are installed on respectively in Upper shaft sleeve seat 11 and the lower shaft block set 4.Upper shaft sleeve seat 11 is identical with lower shaft block set 4 structures, and Upper shaft sleeve seat 11 and lower shaft block set 4 are located at valve body 1 upside and downside respectively.
Be provided with stop nut axle sleeve 12 in the valve body 1, rotary spacing nut 14 is located in the stop nut axle sleeve 12.Be provided with chute 16 in the rotary head 17 on the described valve plate 2, rotary spacing nut 14 bottoms are provided with dop 20, and rotary spacing nut 14 is stuck in the chute 16 by dop 20.Rotary spacing nut 14 can be made slide relative in the chute 16 of valve plate 2.
Valve opening mode of the present utility model is: operator's handle with sleeve 13, the valve rod 3 that is connected on this handle 13 rotates with handle 13, valve rod 3 is when rotating, the threaded stem 15 on valve rod 3 tops also rotates in the internal thread 19 of rotary spacing nut 14, makes valve rod 3 axial motions and rising.Open base valve (being that steel ball 6 is no longer blocked oil duct 7) thereupon, make 9 pressure releases of fluid storeroom.Fluid storeroom 9 both sides produce pressure difference, thereby make ring slider 8 drive valve plate 2 to fluid storeroom 9 one side shiftings, make valve plate 2 and valve body 1 seal failure.At this moment threaded stem 15 also is threaded to rotary spacing nut 14 internal threads 19 upper limits, and handle with sleeve 13 again, and rotary spacing nut 14 is together rotated, and just drives valve plate 2 and rotates, until the valve complete opening.
