Description

[Detailed Description of the Invention] This invention relates to a pressure vessel having a partition door that is inserted from the side and sealed.

When a sealing partition door is inserted from the side, the sealing surface of the door slides in contact with the sealing material of the container body when it is inserted or pulled out, damaging the sealing material and damaging the partition. This may impede the smooth operation of the door.

The purpose of this device is to press the sealing material against the partition door using the internal pressure and spring force when pressurizing the inside, and to seal the partition door.When the partition door is pulled out or inserted, pressure is introduced from the outside to seal the partition door. The object of the present invention is to obtain a pressure vessel which eliminates the above-mentioned disadvantages by operating the sealing members at a distance.

Next, an example of this invention will be explained using drawings.
In Figures 1, 2 and 3, the partition door 3 is inserted into the end 2 of the container 1 from the side in the direction of the arrow 5.

Further, a stopper seat 7 is disposed at the partition door insertion end of the opening of the pressure vessel which separates the inside and outside pressurized with internal pressure p4 by having an opening 6 drawn out in the direction of arrow 5'j5, and the partition door 3 is closed. Let it rest freely at the insertion end point.

A sealing ring 8 connected to the opening and having an annular groove 19 formed therein and having a recessed part 20 cut outwardly into the groove is fitted so as to be slidable in the axial direction. An O-ring 12 is provided on the side end surface for sealing in contact with the partition door 3, and an annular groove 19 is provided on the peripheral surface.
Insert another 01J ring 13 that contacts and seals the inner surface,
Further, a spring housing ring 17 in which a plurality of restraining springs 10 are inserted, which presses the sealing ring with a spring force acting in the axial direction, is disposed behind the sealing ring. By making the gap 21 length wider than the sealing ring 8, the O-ring 12 is separated from the partition door 3 when the sealing ring moves against the spring force, and the outer side of the annular groove is The stop ring 11 is screwed in and disposed on the outside of the recessed part 20 to form another gap 22 between the front surface of the ring and the partition door 3, and the stop ring 11 is inserted into the recessed part 20 at the rear of the stop ring. A sealing section 18 is formed in the front of the end of the recessed part, and a short sealing ring 9 is fitted therein, and 01J rings 15 and 14 are fitted on the arrangement surface of the short sealing ring to seal the top and bottom. The seal ring 8 and the annular groove 19 are sealed, and a conduction hole 16 for introducing a preliminary pressure P'23 from the outside is connected to the sealed section.

Therefore, according to this invention, when the partition door 3 is pulled out from the opening 6, the preliminary pressure P' is applied to the referee compartment 18.
When 23 is applied, if the pressing force that presses the sealing ring 8 in the direction of the spring 10 exceeds the spring force, the sealing ring will move and separate from the partition door, so when the partition door is inserted, It can operate without contacting the sealing ring 01J ring 12, and when the preliminary pressure P'23 is released in the above-mentioned inserted state, the sealing ring 8 is pushed by the spring force of the restraining spring 10, and the sealing ring 8 is pressed against the partition door 3. As the O-ring 12 comes into contact with the O-ring 13
is in contact with the inner surface of the annular groove 19, so that a sealed state can be formed inside the container 1, and when an internal pressure P4 is further applied to the container, the sealing ring 8 is further brought into pressure contact with the partition door 3 and is fitted. Seal by O IJing.

Next, when drawing out the partition door 3, by releasing the internal pressure and applying preliminary pressure to the judgment section 18 to release the engagement between the sealing ring 8 and the partition door 3, the partition door 3 can be drawn out smoothly in the same manner as described above.
