Reference picture 1, the side of valve body 7 is provided with capping 16, and capping 16 is solid by screw bolt 13 and hex nut 14
Dingan County is mounted in valve body 7, and pad 15 is provided between capping 16 and valve body 7.Bonnet 20 is fixedly mounted on the top of valve body 7, valve rod
29 are located in valve body 7, and top passes through bonnet 20, suspension ring 30 to be fixedly mounted on the top of valve rod 29.
Reference picture 1 and Fig. 3, flap 3 are located in valve body 7, and on valve rod 29, along valve under the drive of valve rod 29
The inner chamber of body 7 moves up and down perpendicular to valve seat 2, so that the action that flap 3 is completely disengaged from and closed with valve flowing channel,
And then close and Open valve.The edge of flap 3 carries guiding mechanism 32, and guiding mechanism 32 is contacted with the inwall of valve body 7, right
The elevating movement of flap 3 is oriented to so that flap 3 avoids radial displacement in elevating movement, maintains running orbit not
Become, stability enhancing.Flap 3 carries reinforcement, and reinforcement can increase the intensity of flap 3, reduce the deformation under the condition of high temperature.
Reference picture 1, stand bar seat 17 is fixedly mounted on the top of valve body 7, branch by screw bolt 18 and hex nut 19
Support 31 is fixedly mounted on valve body 7 by stand bar seat 17.
Reference picture 1 and Fig. 3, the valve seat 2 with spherical seal surface are arranged on the top of bottom end cover 1, and bottom end cover 1 passes through full spiral shell
Line bolt 5 and hex nut 6 are arranged on the bottom of valve body 7, and pad 4 is placed between bottom end cover 1 and valve body 7.Using spherical
The valve seat 2 of sealing surface, in valve closing, flap 3 is in close contact with valve seat 2, with good sealing effectiveness.
Reference picture 1 and Fig. 4, forked frame 12 are fixedly mounted on valve rod 29, one end of link 11 by slip-knot bolt and
Lateral pin is arranged on forked frame 12, and the other end is arranged on flap 3 by slip-knot bolt 8 and lateral pin 9, flap 3 and valve rod 29
Connection is adjustable, so that the sealing goodness of fit that adjustable flap 3 causes after installing, wearing and tearing, so as to realize valve long-time stable
Operation.The bottom of valve rod 29 is provided with and cap 10.
Referring to Figures 1 and 2, filler 22 is soft graphite, with some groups, is filled between valve rod 29 and bonnet 20, from
Tight spring 23 is arranged between each group filler 22, and after filler is finished, filler pressing sleeve 25 pushes down filler 22, hold-down grid 27 from outer end
Filler pressing sleeve 25 is pushed down from outer end, hold-down grid 27 is fixedly connected with bonnet 20 by screw bolt 26 and hex nut 28.
As a result of new packing seal structure (stuffing-box), all isolated by filler 22 between bonnet 20 and valve rod 29 so that
Bonnet 20 is reduced at least, not produce relative motion with the contact area of valve rod 29, effectively prevents valve rod 29 by locking, institute
Can be non-maintaining in a long time with valve, and will not leak, stable operation.Installed because 22 points of filler is multistage, filler 22 with
Self-tightening spring 23 is installed, self-tightening spring 23 can compensate in valve running because of letting out that filler abrasion causes between filler 22
Leakage, so valve tightness of the present utility model are more preferable.In the process of running, even if there is a small amount of molecule to enter stuffing-box
In, can also be embedded in lubrication, soft graphite, abrasion can't be brought to valve rod 29.
As a kind of preferred scheme, referring to Figures 1 and 2, it is provided with the outer wall of bonnet 20, positioned at the lower section of filler 22
Fin 21.Fin 21 can effectively reduce the temperature at stuffing-box position, delay filler 22 to carbonize the abrasion for causing and aggravate.
As a kind of preferred scheme, referring to Figures 1 and 2, it is provided with the outer wall of bonnet 20, positioned at the side of filler 22
Lubricating cup 24.Lubricating cup 24 is used for the oiling of filler 22, reduces frictional force of the valve rod 29 in transmission process.
As can be seen here, valve of the invention has advantages below：
(1) during valve opening and closing, the whole process of flap 3 is run in the cavity of valve body 7, does not result in medium and leaks；
(2) with full-bore circulation；
(3) during flap elevating movement, guiding mechanism whole process limits its radial displacement, and it is constant to remain on track, stability
By force；
(4) flap is connected by adjustable balancing device (forked frame+link) with valve rod, after can adjust installation, abrasion
The sealing goodness of fit for causing；
(5) filler and self-tightening spring assembly, enable valve non-maintaining in a long time, will not leak.
Because belljar valve of the present utility model has above-mentioned special structure, so that it can go up the time, fit extensively
For blast-furnace coal powder injection and pulverized coal preparation system.
It should be noted that above-described embodiment does not limit the utility model in any form, all use equivalents or wait
The technical scheme that the mode of conversion is obtained is imitated, is all fallen within protection domain of the present utility model.
