Dismounting and maintenance, rotate bonnet 4 simultaneously and also be able to regulate the holddown spring 3 thrust to spool 21.The upper end of valve rod 2 passes valve
Cap 4, bonnet 4 upper surface has the sealing convex edge 41 of annular around valve rod 2, seals and sets between medial wall, convex edge 41 and valve rod 2
Having soft graphite 5, the upper end sealing convex edge 41 is also bolted with the plug 6 of annular, and this plug 6 is pressed on soft graphite 5, passes through
Soft graphite 5 can be pressed between sealing convex edge 41 and valve rod 2 by plug 6, thus to the gap between valve rod 2 and bonnet 4
Sealing, soft graphite 5 has preferable resistance to elevated temperatures simultaneously, it is to avoid lost efficacy in high temperature and caused gas leakage, peace
Full property is higher.On lateral wall, bonnet 4 upper end, circumference has the sealing 42 of annular, and the upper end port circumference of connecting portion 16 has recessed
Shoulder 161, sealing 42 is positioned at recessed shoulder 161, is provided with soft graphite 5 between sealing 42 downside and recessed shoulder 161 bottom surface, with
Reason, seals also by soft graphite 5 between bonnet 4 and valve body 1, it is to avoid high temperature failure, improves safety.
Shown in Fig. 4, the upper end of valve rod 2 is fixed with knob 7, and the lower end of knob 7 is tubular, at the internal perisporium of knob 7
On there are two symmetrically arranged spacing block sets 71, on connecting portion 16 upper surface circumference there is the limit convex of arc along 162, this is spacing
The radian of convex edge 162 is 90 °, the two ends of air passing hole 211 when a spacing block set 71 and limit convex one end along 162 leans
Respectively with air inlet 11 and to cross QI KOU 13 relative and connect, when another spacing block set 71 and the limit convex other end phase along 162
Against time lateral wall and the air inlet 11 of spool 21 and to cross QI KOU 13 relative, need to be set by knob 7 rotation valve rod 2 when operating
Determining angle, arrange according to concrete structure, in this stop valve, the anglec of rotation of valve rod 2 is 90 °, i.e. by spacing block set 71 with spacing
Convex edge 162 coordinates so that knob 7 is merely able in the range of 90 ° rotate unlatching and the Guan Bi realizing stop valve, operates simpler
Single.
Valve body 1 has one end of air inlet 11 and is arranged with the clamping cap 8 of tubular, and clamping cap 8 is threadeded with valve body 1, pressure
On tight cap 8 inwall, circumference has the compression convex edge 81 of annular, is circumferentially with soft graphite between valve body 1 end face and compression convex edge 81
5, valve body 1 has one end of air inlet 11 and connects air inlet Gas Pipe, compresses convex edge 81 and can compress flexible stone after screwing clamping cap 8
Ink 5 so that soft graphite 5 between the two is extruded, and the soft graphite 5 being squeezed can expanded radially, i.e. soft graphite 5
Be pressed on respectively on the inwall of clamping cap 8 and the outer wall of air inlet Gas Pipe, thus to one end of valve body 1 air inlet, clamping cap 8 and
Seal between gas inlet pipe.Pipe gas blocked valve also includes that adjustable joint 9, one end of adjustable joint 9 have with valve body 1
One end of QI KOU 12 is relative, and is connected by nut 91 locking between adjustable joint 9 and valve body 1, adjustable joint 9 end face and valve body 1
