Abstract

PURPOSE:To provide a gas sealed damper in which a valve body is firmly pressed by a crank mechanism and a resilient member against a valve seat disposed all around the inner surface on a cross section of a damper cylinder. CONSTITUTION:When a shaft 11 disposed eccentrically from the center of a damper cylinder 6 is rotated in the direction of an arrow, even though the valve body 9 tends to vibrate due to a gas flow, the valve body 9 is rotated as dictated by the rotation angle of the shaft 11 to a fully closed position with an area 19 proximate to the third corner of a crank 15. When the shaft 11 is rotated in the direction opposite to the arrow, the resilient member 20 is flexed to produce a reaction against the torque so that the valve body 9 may be fully closed by being pressed against a valve seat 8 with the valve seat 8 near to a crank pin 12 and other bearing member 21 as a pivot.

However, considering that the original function of the damper is to close the gas flow path, the above conventional technology has
There are the following problems. In other words, since the valve seat is divided at the position where the shaft penetrates, leakage of debris inevitably occurs at the divided position.Even if various types of gaskets are attached to prevent this leakage, Since the valve seat essentially covers the entire inner circumference of the damper cylinder, leakage cannot be completely eliminated. In addition, although the mechanism for rotating the valve body using a shaft placed horizontally in the center of the valve body is quite simple, it is difficult to forcefully and steadily press the peripheral edge of the valve body against the valve seat. There are also many difficulties in sealing the damper cylinder body Vc itself. Recently, it has become necessary to almost completely seal off a large amount of poisonous gas using a damper, and the above-mentioned conventional technology is in no way able to satisfy this strict requirement.

A valve seat 8 is provided to protrude from the damper cylinder 6 in the narrow direction over the entire inner circumference of the same new surface (the same horizontal cross section in FIG. 4) of the damper cylinder 6. It goes without saying that the amount of protrusion of the valve seat 8 is sufficient to fully place the circumferential end of the valve body 9 described later to completely block the flow of gas, and it is also necessary to cover the valve seat 8 with 10 tons of gasket. You can also use it as What is important is that the valve seat 8 is provided over the entire circumference of the same cross section, and is not divided in any way or partially removed. This makes manufacturing easier (with the split type, it is also troublesome to adjust the mounting positions of the split valve bodies), and since there are no discontinuous parts anywhere, the gas Sealing performance is dramatically improved.

The valve body 9 has a circular or polygonal shape depending on the cross-sectional shape of the damper cylinder body 6 which is pushed up onto the valve seat 8 and blocks the flow of gas, and has a smaller diameter than the inner diameter of the damper cylinder body 6. It is a hot theory that the inner diameter of the valve seat 8 is also larger.

Of course, the shaft 11 is provided passing through the damper cylinder 6 in a direction perpendicular to the center of the damper cylinder 6, and a force 2- is applied to the portion where the 1° shaft 11 penetrates the damper cylinder 6. 13 is provided, and this color 1
An O-ring 14 is interposed between the shaft 11 and the shaft 11 to prevent gas leakage. In addition, by separating the shirt 11 from the valve body 9, it is possible to use a peeler to make assembly easier, or to make it easier to seal between the damper cylinder 6 and the shirt 11. I should be careful. Further, this shaft 111/'i is connected to a motor or a handle (not shown), and can be rotated mechanically or manually.

(In other words, the crank 15 is also rotated integrally with the rotation of the shaft 11.) The other portion 17 near the apex is rotatably connected to the crank pin 12. The crank pin 12 is supported by two bearing members 18 arranged in parallel on one surface of the valve body 9 on the shaft 11 side in a direction perpendicular to the shaft 11. Crank pin 12 supported in parallel
One vertex of the crank 15 is rotatably connected to the crank 15.

The bearing member 18 serves not only to support the crank pin 12 but also to reinforce the valve body 9. That is, in normal cases, the shaft 11 side of the valve body 9 is slightly closed on the high pressure side (upper part of Fig. 4), and the valve seat 8 side is closed on the low pressure side, but the larger the damper diameter, the more Since excessive pressure is applied to the valve body 9, the valve body 9 is reinforced to prevent it from deforming.

A portion 19 near the third apex of the crank 15 can move into and out of contact with the high-pressure side surface of the valve body 9 . In other words, as described later, 1
The third apex portion 19 is separated from the face of the valve body 9 only in the completely sealed state shown in FIG. 4, but in the half-open state shown in FIG. 6 and the fully open state shown in FIG. , the third vertex vicinity portion 19 contacts the surface of the valve body 9 and transmits the torque of the shaft 11 to the valve body 9. Note that in the half-open and fully open states, the reason why the third apex vicinity portion 19 is brought into continuous contact with the valve body 9 is due to the elastic force e of the elastic member 20.

The elastic member 20 is preferably a plate, one end of which is connected to the shirt 11, and the other end of which is connected to the damper cylinder 6.
With respect to the details, it is coupled to the pin 22 of another bearing member 21 provided at the end of the valve body 9 on the side opposite to the shaft 11 (of course on the high pressure side). In this embodiment, as shown in FIG. 5, the elastic member 2o is disposed to pass approximately through the center of the valve body 9, and the pair of cranks 15 are arranged around the elastic member 20'. It is provided. This arrangement is adopted because the torque of the valve body 11 can be sufficiently transmitted to the valve body 9 to operate it in a well-balanced manner regardless of whether the valve body 9 is opened or closed.

Then, when the shaft 11 is fully rotated in the direction of the arrow in FIG. Part 1 near the vertex of
While the valve body 9 remains in close contact with the surface of the valve body 9, the shaft 11 is
The valve body 9 is rotated through the rotation angle of , and is brought into the fully open state shown in FIG.

Also, the shaft 11' is moved in the direction opposite to the arrow in FIG.
When the elastic member 2o is rotated by t, the elastic member 2o is bent and generates a reaction force against the rotational force, but the valve body 9 is pressed against the valve seat 8 using the valve seat 8 near the crank pin 12 and other bearing members 21 as a fulcrum. It is then brought into the sealed state shown in FIG. In this case, although a bending force is generated in the acid root elastic member 20, the differential pressure between the high gas pressure and the atmospheric pressure acts on the valve body 9 and presses the valve body 9 against the valve seat 8. Therefore, it is not an equivalence problem.

Rather, it should be noted that the valve body 9 is in close contact with the valve seat 8 provided over the entire inner circumference of the same cross section of the damper cylinder body 6, and the sealing function is perfect. ,
Furthermore, the continuation of this sealed state is completely achieved by a crank mechanism provided separately from the valve body 9.

Finally, when comparing the gas-sealed damper according to the present invention with the conventional one, the device of the present invention protrudes over the entire inner circumference of the same cross section of the damper cylinder without dividing the upper part of the valve seat equally. This not only fundamentally improves the sealing performance, but also makes it easy to manufacture.In addition, in the device of the present invention, the valve body and shaft are completely separated, and the shaft is connected to the damper cylinder body. This not only makes it easier to seal the shaft, but also strongly transmits the torque of the shaft to the valve body, improving the movement and stopping performance of the valve body. Furthermore, since the shaft crank mechanism and the elastic member are combined in the device of the present invention, it is possible to perform powerful opening and closing movements, and the valve body remains stable even when there are fluctuations in the gas flow. The shaft rotates as one at the same angle of rotation without flapping.
