Description
Technical Field
The utility model relates to a sealing device technical field especially relates to a high-pressure fire-extinguishing bottle is shock-resistant seal structure.
Background
Along with the development of the aviation industry in China in recent years, the fire protection system of the airplane is also paid more attention, and then higher requirements on the performance of the high-pressure fire extinguishing bottle are put forward; the improvement of the overall performance of the aircraft makes the impact and vibration on the onboard equipment more severe than before, and the temperature of the surrounding environment changes along with the change of the altitude.
This requires that the sealing technique of the high-pressure fire-extinguishing bottle not only can withstand high impact loads and various vibrations, but also has good environmental temperature tolerance and can maintain good sealing performance under various extreme temperature conditions.
SUMMERY OF THE UTILITY MODEL
Objects of the invention
For solving the technical problem who exists among the background art, the utility model provides a high-pressure fire-extinguishing bottle is shock-resistant seal structure, the utility model discloses use two kinds of sealing methods can be better seal, and another kind of sealing method still can play sealed effect after a sealing method became invalid.
(II) technical scheme
The utility model provides an impact-resistant sealing structure of a high-pressure fire-extinguishing bottle, which comprises a fire-extinguishing bottle, a combination valve, a connecting pipe part, a flexible sealing gasket and a rigid sealing gasket;
the top of the fire extinguishing bottle is provided with a bottle neck; one end of the connecting pipe part is communicated with the combined valve, and the other end of the connecting pipe part extends into the bottle neck part and is connected with the bottle neck part; the rigid sealing gasket is arranged at the bottom of the combined valve, is coaxially arranged with the bottle neck and is in sealing connection with the bottle neck; the bottle neck part, the flexible sealing gasket and the connecting pipe part are coaxially arranged from outside to inside, and the flexible sealing gasket is in sealing connection with the bottle neck part and the connecting pipe part.
Preferably, the top of the bottle neck is provided with a V-shaped groove for inserting a rigid seal.
Preferably, the flexible sealing gasket is an O-shaped ring; the rigid sealing gasket is a copper gasket.
Compared with the prior art, the above technical scheme of the utility model following profitable technological effect has: two sealing modes are adopted between the fire extinguishing bottle and the combined valve, namely, the fire extinguishing bottle and the combined valve are in sealing connection through a flexible sealing gasket and a rigid sealing gasket; the flexible sealing gasket has small sensitivity to impact and vibration, and even if a gap appears at a joint, the gap can be automatically filled through the elasticity of the material of the flexible sealing gasket, so that the sealing performance of the joint is always kept; for the rigid sealing gasket, because the thermal expansion coefficient of the metal material is smaller, the deformation amount of the copper gasket in the V-shaped groove is slightly reduced at low temperature, and the sealing performance of the position can be still ensured; the metal expands at high temperature, the deformation amount of the copper pad in the V-shaped groove is increased, and the sealing property is improved; the two sealing modes can be used for better sealing, and the other group can still play a role in sealing after one sealing mode fails.

Fig. 1 is the utility model provides a high-pressure fire-extinguishing bottle impact-resistant seal structure's structural schematic diagram.
Reference numerals: 1. a fire extinguishing bottle; 101. a bottle neck portion; 2. a combination valve; 201. a connecting pipe portion; 3. a flexible gasket; 4. a rigid gasket.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
As shown in fig. 1, the utility model provides an impact-resistant sealing structure of a high-pressure fire-extinguishing bottle, which comprises a fire-extinguishing bottle 1, a combination valve 2, a connecting pipe part 201, a flexible sealing gasket 3 and a rigid sealing gasket 4;
the top of the fire extinguishing bottle 1 is provided with a bottle neck part 101; one end of the connecting pipe part 201 is communicated with the combination valve 2, and the other end of the connecting pipe part 201 extends into the bottle neck part 101 and is connected with the bottle neck part 101; the rigid sealing gasket 4 is arranged at the bottom of the combination valve 2, the rigid sealing gasket 4 is coaxially arranged with the bottle neck 101, and the rigid sealing gasket 4 is hermetically connected with the bottle neck 101; the bottle neck portion 101, the flexible seal packing 3 and the connecting tube portion 201 are coaxially arranged from outside to inside, and the flexible seal packing 3 is sealingly connected to the bottle neck portion 101 and the connecting tube portion 201.
In an alternative embodiment, the top of the bottle neck 101 is provided with a V-groove for embedding the rigid seal 4.
The rigid packing 4 is deformed in the V-shaped groove, and the rigid packing 4 can provide a good sealing property.
In an alternative embodiment, the flexible seal 3 is an O-ring; the rigid seal 4 is a copper pad.
It is noted that the O-ring is simple to manufacture, reliable in function, and simple in installation requirements; the small coefficient of thermal expansion of the copper pad ensures good sealing.
