A kind of above-mentioned low torque high-voltage bidirectional plug valve, wherein, interior hexagonal shrinkage pool is equipped in the adjusting nut, it is described interior Hexagonal shrinkage pool and the first discharge orifice are coaxially disposed.
A kind of above-mentioned low torque high-voltage bidirectional plug valve, wherein, the limiting wedge shaped structure in spacer ring section.
A kind of above-mentioned low torque high-voltage bidirectional plug valve, wherein, interior hexagonal groove is equipped in the knob, the L-shaped is dialled Boom end coordinates with interior hexagonal groove shape.
The beneficial effects of the utility model are:
The utility model structure novel is compact, using adjusting nut, upper valve base, valve ball and the lower valve base set gradually, dress Formula lessens care and maintenance difficulty, with the structure of the knob with several annular seal grooves, upper valve base and lower valve base, and Using waveform spring, O-ring seals and wedge shape limiting spacing ring structure of leather assembling, the hard sealing structure of metal to metal is formed, effectively Compensate for tolerance range on valve body between through-hole and upper valve base and lower valve base, between valve body mounting hole and knob and in pressure medium Under elastic deformation, drilling fluid can be made without pressure drop to reserve for one's own use and flowed through, solve petroleum industry drilling well in two-way exchange medium conveyed Sealing problem present in journey, the rotation of 90 ° of driving lever drive knob can valve ball rotate with, realize that flow path opens and closes, effectively avoid Leakage, blowout phenomenon.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model.
(In figure, valve body 1, upper through-hole 2 and lower through-hole 3, adjusting nut 4, upper valve base 5,6 lower valve base 7 of valve ball, matching thread 8, interior hexagonal shrinkage pool 9, the first discharge orifice 10, mounting hole 11, the second discharge orifice 12, knob 13, annular seal groove 14, O-ring seals 15, L-shaped driving lever 16 limits spacer ring 17, interior hexagonal groove 18, waveform spring 19).
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.
A kind of low torque high-voltage bidirectional plug valve including valve body, is equipped with upper through-hole and lower through-hole in the valve body, it is described on Through-hole is connected and is coaxially disposed with lower through-hole, wherein, it is equipped with and adjusts successively by upper through-hole to lower through-hole direction, in the upper through-hole Nut, upper valve base, valve ball and lower valve base are equipped with matching thread, the tune between the adjusting nut outer wall and upper through-hole wall It saves and interior hexagonal shrinkage pool is equipped in nut, the first discharge orifice, and end and valve ball outer wall shape are equipped in the upper valve base and lower valve base Shape coordinates, and the interior hexagonal shrinkage pool and the first discharge orifice are coaxially disposed;
