Club moves down, and lifting fly rod also declines, until the active tunnel port on spacing steel ball and bonnet contradicts.Fly rod is lifted to work as
In round steel be made of stainless steel, prevent from getting rusty, improve service life, and lift the interior bar outer wall among fly rod set it is outer
Screw thread, greatly facilitate the assembling of seal washer.The setting of double-decker also ensure that the structural strength of its own and structure are steady
It is qualitative.
The utility model is further arranged to：The seal washer is sheathed in interior bar, and seal washer upper surface is pressed with gear
Circle, the back-up ring is placed in interior bar and the diameter of back-up ring and the external diameter of active tunnel are equal；Between seal washer lower surface and ball float
Interior bar on be threaded with two nuts.
By using above-mentioned technical proposal, the setting of back-up ring further improves the sealing effectiveness to exhaust chamber, back-up ring and
Active tunnel contradicts, air-tight movable passage, and fixation of the cooperation realization of two nuts to seal washer, ensures on back-up ring and interior bar
The Stability Analysis of Structures of seal washer.
The utility model is further arranged to：The spacing steel ball upper and lower ends respectively constitute limited location groove and locating slot,
Connected between locating slot and stopper slot by through hole, interior bar is stretched into through through hole and extended in stopper slot from locating slot, and this is extended
Locking nut is arranged with interior bar in stopper slot, the round steel inserts locating slot and contradicted with locating slot bottom land.
By using above-mentioned technical proposal, the setting of locating slot substantially increases the stability of round steel assembling, and stopper slot
Setting realize the assembling of interior bar and spacing steel ball, in assembling process interior bar is hidden in stopper slot, protects two
The connective stability of person.
