ンパを設置するが、特に高い締め切り性が必要な
場合には、一般にスライドゲートダンパを採用し
ている。 In a boiler duct, etc., a damper is installed in the middle of the flow path to adjust the flow rate and close off the fluid, but when particularly high shutoff performance is required, a slide gate damper is generally used.
第１図は、従来のスライドゲートダンパの構造
を示す。 FIG. 1 shows the structure of a conventional slide gate damper.

これにより全閉及び全開状態となる。 In FIG. 1, there is a damper box 3 called a door pocket on the outside of a slide gate damper body 2 installed in the middle of a duct 1, and a drive shaft 5 is rotated by a drive device 4 at the tip of the damper box 3. Along with the rotation, the partition plate 6 operates vertically or horizontally,
This results in a fully closed and fully open state.

る。 The present invention was devised to solve these conventional problems.The partition plate is divided into a plurality of partition plates with a U-shaped cross section, and among these partition plates, the most advanced partition plate on the driving side is connected to a drive chain disposed so as to be movable forward and backward in the damper box, and another partition plate is connected to the most extreme partition plate on the driving side or to another partition plate, the partition plate having a U-shaped cross section. The partition plates are linked together via the protrusions on the ends of the plates, and when the damper is fully opened, each partition plate is stacked and stored in the damper box, reducing the size of the damper box and reducing the overall size of the damper to reduce overflow. This allows slide gate dampers to be installed at certain locations.

れてダンパボツクス１３に収納される。 In FIGS. 2 and 3, there is a damper box 13 on the outside of the slide gate damper main body 12 installed in the middle of the duct 11, and the damper box 13 can be moved forward and backward within the damper box 13 by a drive device 14 at the tip of the damper box 13. The disposed drive chain 15 is moved, and the drive chain 15 operates the driving side partition plate 16a, which has a U-shaped cross section, vertically or horizontally, and also moves the driven side partition plate 16b, which also has a U-shaped cross section, between these partitions. It is operated in conjunction with the drive-side partition plate 16 through a protrusion at the end of the partition plate formed by the U-shaped cross section of the plate, thereby creating a fully closed and fully open state.When fully opened, each partition plate has a reference number. As shown by 16'a and 16'b, they are stacked and stored in the damper box 13.
なお、仕切板１６ａ，１６ｂに対する内部流体

て、ダクト１１を全閉することが出来る。 As described above, according to this embodiment, there is a damper box 13 on the outside of the damper body 12 provided in the middle of the duct 11, in which the drive device 14 is provided near the tip.
When the duct 11 is completely closed by storing the partition plates 16a and 16b each having a U-shaped cross section one on top of the other, the plurality of partition plates 16a and 16b in the damper box 13 are The duct 11 can be completely closed by moving the mold partition plates 16a, 16b downward, to the left, or to the right.

の突起を介して連動するように連結される。 In addition, according to the embodiment described above, the partition plate is divided into two parts.
Although it is divided into separate partition plates 16a and 16b, the number of divided partition plates can be increased. and,
In this case, the most extreme partition plate 16a on the drive side is connected to the drive chain 15, and the other partition plates 16b...
is interlockingly connected to the partition plate 16a or other partition plate through a protrusion at the end of the partition plate, which has a U-shaped cross section.

む。 As mentioned above, according to the present invention, the partition plate of the slide gate damper is divided into a plurality of parts, and when the damper is fully opened, the partition plates 16a, 16b, etc. are stacked and stored in the damper box 13. The height B of box 13 is the damper diameter C
It is possible to reduce the size of the damper box by making the damper box considerably lower than that of the damper box, thereby downsizing the entire damper and installing the slide gate damper in a narrow space. Further, according to the present invention, the cross sections of the plurality of divided partition plates 16a, 16b... are made into a U-shape, and among these divided partition plates, the most advanced partition plate on the driving side
6a to the drive chain 15, and the other partition plates 16b... are interlocked with the partition plate 16a or other partition plates through a protrusion at the end of the partition plate formed by the U-shaped cross section. Since the driving device 14 is connected to the driving device 14, only one driving device 14 is required.

め、作動不良の心配は全くない。 The interlocking movement of the partition plates is such that the most extreme partition plate 16a on the driving side is moved by the forward and backward running of the drive chain 15, and as the partition plate 16 moves, the other partition plates 16b is pulled and moved, and in the closed position, each partition plate is pulled from the top and bottom or from the left and right, so there is no fear of malfunction.

ことができる。 Moreover, according to such a configuration, since the partition plate is moved by the forward and backward movement of the drive chain 15, the partition plate can be moved vertically or horizontally with the same configuration. Moreover,
This drive chain 15 is arranged so as to be movable forward and backward within the damper box 13, and does not penetrate the wall of the damper box 13, so there is no problem of fluid sealing at the chain penetrating portion. It should be noted that even if the partition plate is divided into a plurality of pieces, sufficient closing performance can be ensured, but even higher closing performance can be obtained by suitably combining sealing metal fittings at the ends of the partition plate.
