Problems solved by technology

However, an additional steel plate is used to close the door frame on site, which is bulky and heavy, and has potential safety hazards, which is not convenient for transportation and handling. In addition, the pressing plate of this technical solution needs to process several threaded holes on the door frame to fix the overpressure chamber, which is difficult and expensive to process. Work is time-consuming, affecting the appearance of the door frame and destroying the overall strength of the door frame. It can be seen that the prior art civil air defense equipment testing platform and air tightness testing method are difficult to be popularized and used in engineering practice due to the above defects

Embodiment 1

[0062] Embodiment 1 (the airtight door is a rectangular structure)

[0063] See attached figure 2 , a kind of test device of the method for realizing the on-site airtightness test of the airtight door according to the first embodiment of the present invention, which consists of a rigid frame, a pressing mechanism 11, a gasket 13, and an air pressure cavity 15 formed with the door frame 2 and the door leaf 1 The closed membrane is composed of 3.

[0064] The rigid frame is a rectangular frame 10 corresponding to the rectangular door frame 2. It is located in the inner cavity of the door frame 2. There is a gap between the rigid frame and the inner side of the door frame 2. The pressing mechanism 11 is distributed along the rigid frame and expands and contracts to the outside of the rigid frame. , the gasket 13 is an annular structure that is laid along the inner side of the door frame 2, and the surrounding edge of the sealing diaphragm 3 is placed into the gasket 13; .

Embodiment 2

[0074] Embodiment 2 (the airtight door is a circular structure)

[0075] See attached Figure 7 , 8 And attached Figure 9 , as a modification, the difference between the second embodiment and the first embodiment is that the rigid frame is an annular frame 23 corresponding to the door frame 21. The three sections of arc-shaped rods 233 are assembled through butt joints. Corresponding spherical grooves 231 and spherical protrusions 230 are arranged between the two opposite sections of the joints. After butt joints, a complete ring is formed. When the circular door frame 21 When the diameter is larger, the rigid frame 23 can also be decomposed into more than 3 sections of circular arc butt joint assembly, and in order to avoid the deformation of the circular frame 23 during use, multiple a radial support rod. Equally, the profile of sealing gasket 24, sealing diaphragm 22 is a ring shape, and the pressing mechanism 11 is distributed along the outer circumference of the annu...

Abstract

The invention discloses a sealed door filed airtight test method and test device. An inlet valve and a piezo-meter / pressure sensing amplification instrument is arranged on an enclosed diaphragm; the enclosed diaphragm is prepared by rubber, leather or textile materials which can endure gas pressure; the enclosed diaphragm and the door frame of a sealed door are in sealed connection by a mechanical compression device. The test device comprises a rigid framework, a compaction mechanism, a sealing gasket, and the enclosed diaphragm forming an air pressure chamber with the door frame and a door leaf; the shape and size of the rigid framework match the shape and size of the inner side of the door frame; the compaction mechanism is distributed along the periphery of the rigid framework, and is flexible towards the outside of the periphery of the rigid framework; the sealing gasket is a circular structure tightly laying around the periphery of the inner side of the door frame; the peripheral edge portion of the enclosed diaphragm is inputted in the sealing gasket, and the sealing gasket can be compressed towards the inner side wall direction of the door frame by adjusting the compaction mechanism. The test device is portable, and fast to test, and does not damage the door frame.

Description

technical field [0001] The invention relates to the field of engineering and engineering tests, in particular to a method and a test device based on an on-site airtightness test of an airtight door. Background technique [0002] Airtight doors are widely used in the mouth of chemical industry, civil air defense, shipbuilding, aerospace and other fields. Its function includes isolating gas and liquid to ensure the safety of personnel and equipment. , Airtight doors are used to block shock waves, poisonous gases, and early nuclear radiation during wartime. In the fields of aircraft, ships, submarines, and aerospace, airtight doors are used to isolate pressure gases and liquids. The airtight door usually includes a door frame, a door leaf, a locking device and a sealing rubber strip. The sealing rubber strip is arranged between the door frame and the door leaf. When the door leaf is locked, it is sealed by the sealing rubber strip between the door frame and the door leaf. Befo...
