Abstract
The utility model provides a rescue capsule decompression system which comprises a general control valve, a decompression pipe, a tee joint, a hand-operated decompression valve, a stop valve and an automatic decompression valve. The two ends of the decompression pipe are connected with the general control valve and the tee joint respectively, the other two connectors of the tee joint are connected with the hand-operated decompression valve and the stop valve respectively, and another connector of the stop valve is connected with the automatic decompression valve. The rescue capsule decompression system has the advantages that through the automatic decompression system and the hand-operated decompression system, when one decompression system fails, the other decompression system can still decompress a rescue capsule, the stop valve and the general control valve can prevent poisonous gas outside the capsule from reversely charging when the decompression system is damaged.
Description
Technical field
The utility model relates to survival capsule, particularly the survival capsule pressure relief system.
Background technology
For the generation of Prevention with reply mine disaster accident, be provided with a plurality of portable survival capsules in mine laneway, survival capsule provides the hedging confined space of a safety for the hedging personnel.When the survival capsule air pressure inside is greater than safe atmospheric pressure value, can causes damage to escape capsule body and internal unit, and can hedging personnel's safety be constituted a threat to.Therefore when the survival capsule air pressure inside is too high, to carry out pressure release to survival capsule, now will use pressure relief system, existing pressure relief device mostly adopts the releasing pressure automatically system, once the generation mine disaster, survival capsule will be impacted, if the releasing pressure automatically system is damaged, will cause that the cabin internal gas pressure raises or causes that the contrary of toxic gas fills out of my cabin, jeopardizes the life security of personnel in cabin.
Solve these defects therefore be necessary to design a kind of survival capsule pressure relief system.
The utility model content
The utility model proposes the survival capsule pressure relief system, solved when in the prior art, pressure relief system is damaged and caused that the cabin internal gas pressure raises or the contrary defect of filling of toxic gas out of my cabin.
The technical solution of the utility model is achieved in that
The survival capsule pressure relief system, comprise master control valve, relief tube, threeway, manual relief valve, stop valve and automatic decompression valve, the two ends of described relief tube connect respectively described master control valve and described threeway, two other interface of described threeway is connected with described stop valve with described manual relief valve respectively, and another interface of described stop valve is connected with described automatic decompression valve.
Further, described master control valve, described relief tube, described threeway, described manual relief valve, described stop valve and described automatic decompression valve are arranged on survival capsule inside.
Further, described manual relief valve and described automatic decompression valve are connected with discharge pipe, and the outlet of described discharge pipe is arranged on outside survival capsule.
The beneficial effects of the utility model are:
1, adopt releasing pressure automatically and manual two pressure relief systems of pressure release, when guaranteeing that a pressure relief system goes wrong, also have another pressure relief system to carry out pressure release to survival capsule.
2, stop valve and master control valve can prevent that pressure relief system from destroying the time, the contrary of toxic gas fills out of my cabin.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
With reference to Fig. 1, survival capsule pressure relief system 1, comprise master control valve 2, relief tube 3, threeway 4, manual relief valve 5, stop valve 6 and automatic decompression valve 7, the two ends of described relief tube 3 connect respectively described master control valve 2 and described threeway 4, two other interface of described threeway 4 is connected with described stop valve 6 with described manual relief valve 5 respectively, and another interface of described stop valve 6 is connected with described automatic decompression valve 7.
Further, described master control valve 2, described relief tube 3, described threeway 4, described manual relief valve 5, described stop valve 6 and described automatic decompression valve 7 are arranged on survival capsule inside.
Further, described manual relief valve 5 and described automatic decompression valve 7 are connected with discharge pipe, and the outlet of described discharge pipe is arranged on outside survival capsule.
Automatic decompression valve 7(opens and closes threshold values 350Pa) can be at the situation releasing pressure automatically of superpressure; manual relief valve 5; when when automatic decompression valve 7 breaks down; can carry out manual pressure release; make in cabin to keep suitable air pressure; perhaps can carry out manual pressure release at the cabin comfort degree according to personnel, the setting of stop valve 6 and master control valve 2 prevents out of my cabin that gas is contrary and fills and effectively protect during the system failure.
The beneficial effects of the utility model are:
1, adopt releasing pressure automatically and manual two pressure relief systems of pressure release, when guaranteeing that a pressure relief system goes wrong, also have another pressure relief system to carry out pressure release to survival capsule.
2, stop valve and master control valve can prevent that pressure relief system from destroying the time, the contrary of toxic gas fills out of my cabin.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
