The positions of the seal detection through hole A and the seal detection through hole B are positioned at the upper and lower diagonal positions of the common door leaf.
The structure of the seal corresponding to the tree seal groove a and the tree seal groove B is a combination of a dovetail groove section and a straight groove section.
The outer ring of the straight groove-shaped section is provided with a bulge.
The protrusions are wavy.
The protrusions are zigzag.
And a groove is formed in the contact part of the sealing element and the common door leaf, and common square stainless steel is arranged at the contact part of the sealing element and the common door leaf.
The beneficial effects obtained by the utility model are as follows:
1. the sealing structure is simple, the machining is convenient, and the machining cost is low.
2. The door leaf of airtight door is carbon steel generally, and carbon steel rust easily, adopts the mode of mopping to prevent corrosion in the seal groove generally, and the paint is easy to drop for a long time, and the medium of sealed door inside just is easy to leak from the paint that drops. The sealing groove is made of stainless steel, so that common anti-corrosion measures are not needed, and the sealing piece and the sealing groove can be in direct contact for compression sealing. Therefore, the leakage of the airtight door can be greatly reduced by adopting the stainless steel sealing groove.
3. Two annular sealing grooves are adopted, two penetrating through holes are formed in the middle of each annular sealing groove, and a gas quick connector is connected to the other side of each through hole, so that other devices are not needed, the gas tightness detection device can be directly connected to quickly detect the leakage rate of the gas tightness door, and the sealing test efficiency is improved.
4. When the sealing element is installed, one sealing or two sealing can be installed in the two annular sealing grooves according to actual conditions. The cost of the seal can be reduced to half when one seal is installed. If the sealing member is installed on the inner side, the sealing member for test can be installed on the outer side to perform air tightness detection when the tightness of the air tight door needs to be detected. And similarly can be mounted on the outside. When the sealing element is arranged on the outer side, the heat transferred to the sealing element by the temperature in the room through the airtight door can be greatly reduced, and therefore the service life of the sealing element is prolonged. If two seals are arranged, the sealing effect of the airtight door is better, double protection is realized, and the damage of one seal piece does not affect the integral tightness of the airtight door.
5. The annular dovetail groove and straight groove structure is characterized in that a bulge is arranged on the outer ring of the straight groove section in the sealing element structure. The tightness of the sealing element and the stainless steel straight groove is enhanced by the structural combination of the sealing element and the stainless steel straight groove, and the sealing element can be effectively prevented from loosening and falling from the sealing groove by double-channel protection.
6. The sealing structure is simple and convenient to operate when the sealing element is disassembled and assembled.
7. The whole door is made of stainless steel, so that the cost is high; if carbon steel is adopted, medium leakage is easy to occur. On the basis of carbon steel, a stainless steel seal groove/square stainless steel is arranged in a slotting way, so that the manufacturing cost of the whole door frame is reduced.
