Description

Sealing protection and opening method of observation device under action of explosion impact
Technical Field
The invention belongs to the technical field of design of an explosion observation device, and is mainly used for explosion impact resistant sealing protection and explosion opening of the observation device in a closed space.
Background
In the field of explosion observation, remote observation means is generally adopted or observation is carried out after explosion in an explosion field, and the requirement of use in a closed space cannot be met. The protection of the observation device is designed according to GB3836.1-2010 explosive environmental equipment general requirements, and the protection requirements of the observation device for the explosion phenomenon in the large-equivalent short-distance closed space cannot be met. The explosion is difficult to be applied to a closed space when entering for observation or remote observation. Due to the ultra-strong impact force of explosion and high temperature and high pressure, the existing observation device with the common protection level cannot be suitable for a large-equivalent short-distance explosion environment.
Disclosure of Invention
The purpose of the invention is as follows: the invention is mainly used for the protection method of the observation device which is placed in a closed space in advance, and can effectively seal and protect the observation device at the moment of explosion and open the observation device after explosion.
The technical scheme is as follows: the anti-explosion end cover, the sealing end cover and the device main body form a closed cavity, and the pushing device and the observation device are arranged in the cavity; the pushing device and the observation device are filled and fixed by adopting flexible filler, rigid contact does not exist among all parts, the anti-explosion end cover and the sealing end cover are sequentially pushed out by the pushing device after explosion to realize opening, and then the observation device is pushed out to observe the explosion phenomenon; a labyrinth seal ring is arranged in the anti-explosion end cover, and a sealing system consisting of a Y-shaped one-way seal ring and a high-temperature resistant O-shaped seal ring is assembled on the sealing end cover.
The method utilizes a sealing system formed by an anti-explosion end cover and a sealing end cover to protect an observation device at the moment of explosion, and the observation device is ejected out for observation through an ejecting device (an electric push rod) after explosion.
Drawings
Fig. 1 is a functional structure diagram of an anti-explosion device for sealing protection and opening of an observation device under the action of explosion impact.
Has the advantages that: the invention utilizes a series of sealing protection methods consisting of the anti-explosion end cover, the sealing end cover and the device main body to effectively protect a common observation device, utilizes the pushing device to eject the anti-explosion end cover and the sealing end cover out after explosion to realize opening after explosion, ejects out the observation device for observation, and realizes the observation of close-range explosion phenomenon after explosion in a closed space. The method is simple and reliable, and the device has low processing cost.
Detailed Description
The working principle of the method is as follows: the anti-explosion end cover, the sealing end cover and the device main body form a closed cavity, and the pushing device and the observation device are arranged in the cavity; at the moment of explosion, the anti-explosion end cover resists shock waves and fragments, and the design of a labyrinth seal ring in the anti-explosion end cover reduces super-strong impact force; the sealing system that Y type one-way sealing washer and anti high temperature O circle are constituteed blocks to the shock wave that openly comes on sealed end cap to Y type one-way sealing washer can crowd the device main part more under the malleation effect, strengthens sealed effect, thereby blocks to explode back high temperature high-pressure gas and get into the cavity, guarantees observation device's safety.
The pushing device and the observation device are filled and fixed by flexible fillers, rigid contact does not exist between the components, and the mode can effectively reduce damage caused by impact vibration. After explosion, the anti-explosion end cover and the sealing end cover are sequentially ejected out through the ejecting device, and then the observation device is ejected out to observe the explosion phenomenon.
The method is mainly characterized in that: the anti-explosion end cover, the sealing end cover and the device main body form a sealing system; and the pushing device pushes the anti-explosion end cover and the sealing end cover out in sequence after explosion to realize opening, and pushes the observation device out to observe.
The antiknock device realizes effective sealing protection on a common observation device under the actions of explosion impact and 20MPa quasi-static pressure after explosion, and the temperature in a cavity is measured to be not more than 35 ℃; and the antiknock end cover and the sealing end cover can be ejected out to be opened after explosion, and the observation device is ejected out to be observed.
