The supreme top, top of bar arranges external screw thread, and described valve stem nut is the most spacing to be fixed in described installation set, described valve
Stem nut is threaded in described valve rod upper end, and described handwheel is nested with on the described valve stem nut installed above set, described
Locking nut is threaded in described valve stem nut upper end.
The present invention passes through rotation hand wheel, the unlatching of control valve, closedown, and handwheel rotarily drives valve stem nut and rotates, valve rod spiral shell
Mother makes valve rod move up and down by screw thread, and valve rod drives flap and valve seat folding；Valve rod is monolithic construction, makees lifting fortune
Dynamic, during valve closing, the sealing surface of Reliable guarantee flap fits like a glove the sealing surface of valve seat, without crooked, seals reliable.
Packing seal mechanism of the present invention includes filler, gland, clamping screw, nut, the upper end of described valve gap
And arranging stuffing-box between valve rod, described filler is arranged in described stuffing-box, and described gland is set in outside described valve rod,
Described gland is pressed on described filler, and described clamping screw lower end is connected to described valve gap upper end by bearing pin, split pin,
Described clamping screw is passed through described gland, and described nut thread is connected on described clamping screw, passes through tightening nut
Filler is compressed by lower pressure gland.Filler plays insurance sealing function.Once corrugated tube damages, and medium can effectively be blocked up by filler
Live, will not leak outside, here function as insurance sealing function.
Valve body of the present invention is the oval valve body of symmetry form.This valve body not only fluid resistance is little, more just
Installation in pipeline connects, and solves conventional plain edition valve body and installs the problem that string stud is inconvenient.
