Problems solved by technology

[0003] Since the explosion-proof tanks of the prior art are used to meet the temporary storage and transportation needs of suspected explosives such as gunpowder explosions with small equivalents, and the prior art does not have chemical explosion-proof tanks for storing and transporting biochemical explosives, therefore, So far, there are no literature reports and practical applications on the test methods of anti-fragment penetration and sealing performance of chemical explosion-proof tanks

Embodiment 1

[0021] Embodiment 1, a method for testing the anti-fragment penetration and sealing performance of a chemical explosion-proof tank according to this embodiment, comprising the following steps:

[0022] 1) Static sealing performance appraisal

[0023] (1) Before the test, check that the pipeline connection is normal, inflate the chemical explosion-proof tank to the pressure gauge pressure value of 1.02MPa, test that there is no leakage at each interface of the pipeline, observe that the pressure gauge value does not change after rising from 0 to 1.02MPa, and release the chemical explosion-proof tank No leakage before entering the water tank;

[0024] ⑵Put the pressurized anti-chemical and explosion-proof tank into the water tank. After the chemical and explosion-proof tank is completely submerged in the water, the test personnel observe that there are no bubbles on the water surface;

[0025] (3) After observing that there are no bubbles on the water surface and no change in t...

Embodiment 2

[0041] Embodiment 2, the specific steps of this embodiment are as follows:

[0042] 1) Static sealing performance appraisal

[0043] (1) Check that the pipeline connection is normal before the test, inflate the chemical explosion-proof tank to the pressure gauge pressure value of 1.01MPa, test that there is no leakage at each interface of the pipeline, and observe that the pressure gauge value does not change after rising from 0 to 1.01MPa to ensure the chemical explosion-proof tank No leakage before putting into the water tank;

[0044] (2) Put the pressurized anti-chemical and explosion-proof tank into the water tank, and after the chemical and explosion-proof tank is completely submerged in the water, the test personnel observe that there are no bubbles on the water surface;

[0045] (3) After observing that there are no bubbles on the water surface and no change in the value of the pressure gauge, keep it in its state for 24 hours. During this period, the test personnel o...

Abstract

The invention relates to a method for testing the fragment penetration resistance and sealing performance of a chemical defense and explosion-proof tank. The method is characterized by comprising the following steps: step 1) static sealing performance identification concretely including (1) checking pipeline connection before testing, and inflating the chemical-defense and explosion-proof tank; (2) putting the pressurized chemical-defense explosion-proof tank into a water tank; (3) after observing that no bubble is generated on the water surface and the value of the pressure gauge is unchanged, keeping the state for 24 hours; and (4) after the test, taking out the chemical-defense explosion-proof tank; and step 2) fragment penetration resistance and sealing performance test concretely comprising (1) placing the red simulated bomb for test at the explosion center position of the chemical and explosion-proof tank for detonation; (2) after field safety is checked after explosion, maintaining the pressure for 2 hours after the pressure is confirmed to be stable, and checking the structures and the tank body of each part of the chemical defense and explosion-proof tank; (3) electrically opening the chemical defense and explosion-proof tank; (4) checking whether the chemical defense and explosion-proof tank has a gas leakage phenomenon or not; and (5) disassembling the composite armor of the lining, measuring the penetration depth of the simulated bomb sheet to the composite armor, and summarizing the measurement results.

Description

technical field [0001] The invention relates to performance testing of explosion-proof equipment, which is a method for testing the anti-fragment penetration and sealing performance of a chemical-proof explosion-proof tank. Background technique [0002] The explosion-proof tanks of the prior art are mainly used for storage, transfer and designated location destruction of suspected gunpowder and explosives in places such as subways, airports, docks, stations, stadiums, exhibition venues, squares, passenger and cargo ships, and railway trains. This kind of explosion-proof tank has a relatively simple structure and does not have a chemical-proof function, so it is not suitable for storage, transfer and destruction of designated places for biochemical explosives. Once the biochemical explosive explodes in the explosion-proof tank, the toxic and harmful gas (liquid) produced cannot be handled safely. However, in our country, there are still abandoned ammunition and biochemical e...
