Abstract
The utility model discloses an aircraft cabin internal valve. The aircraft cabin internal valve comprises a valve body. A gas passageway is arranged in the valve body. One end of the gas passageway is provided with a gas passageway external connector. A gas control valve is arranged on the valve body. The gas passageway is connected with an overpressure gas passageway which is connected with an exhaust connector body. A rupture disk is arranged in the exhaust connector body. An exhaust passageway external connector communicated with the outside world is arranged at the tail end of the exhaust connector body. A sealing gasket is arranged between the exhaust connector body and the rupture disk. By means of the aircraft cabin internal valve, gas is directly exhausted out of a cabin through the exhaust passageway external connector in the overpressure exhausting process safely and reliably.
Description
Technical field
The utility model relates to a kind of aircraft cabin inside valve.
Background technique
Conventional valve in the time being provided with overpressure protector, in the time that superpressure is lost heart, be directly by media discharge in atmosphere.And aircraft cabin inside valve is not allow medium to be directly discharged in cabin in the time that superpressure is lost heart.The structure problem that solves valve can reach the emission request that changes medium when aircraft cabin is inner to lose heart by valve superpressure.
Summary of the invention
Can not meet for what overcome that existing aircraft cabin inside valve exists the shortcoming that media discharge requires in the time that superpressure is lost heart, the utility model provides a kind of aircraft cabin inside valve that media discharge requires can effectively solve superpressure and lose heart time.
The technical solution adopted in the utility model is:
Aircraft cabin inside valve, comprise valve body, in described valve body, be provided with gaseous state passage, described gaseous state passage one end is provided with gaseous state passage external tapping, described valve body is provided with gaseous state control valve, it is characterized in that: described gaseous state passage connects a superpressure gaseous state passage, and described superpressure gaseous state passage connects a disappointing joint body, in described disappointing joint body, be provided with rupture disk, and described disappointing joint body end is provided with the disappointing passage external tapping being in communication with the outside.
Further, between described disappointing joint body and described rupture disk, be provided with sealing gasket.
The disappointing passage external tapping that the utility model is provided with superpressure gaseous state passage and is in communication with the outside on valve body.In the time that pressure reaches explosion requirement, cause rupture disk explosion, gaseous state carries out safety dumping by the passage external tapping that loses heart, and prevents tank body blast.
The beneficial effects of the utility model are embodied in: when valve loses heart in superpressure, directly gas discharged outside cabin by the passage external tapping that loses heart, and safe and reliable.
Accompanying drawing explanation
Fig. 1 is the inner structural representation with valve of the utility model aircraft cabin.
Fig. 2 is the decomposed view of Fig. 1.
Embodiment
See figures.1.and.2, aircraft cabin inside valve, comprise valve body 1, in described valve body 1, be provided with gaseous state passage 2, described gaseous state passage 2 one end are provided with gaseous state passage external tapping 3, described valve body 1 is provided with gaseous state control valve 4, described gaseous state passage 2 connects a superpressure gaseous state passage 9, described superpressure gaseous state passage 9 connects a disappointing joint body 5, in described disappointing joint body 5, be provided with rupture disk 6, and described disappointing joint body 5 ends are provided with the disappointing passage external tapping 7 being in communication with the outside.
Further, between described disappointing joint body 5 and described rupture disk 6, be provided with sealing gasket 8.
The disappointing passage external tapping 7 that the utility model is provided with superpressure gaseous state passage 9 and is in communication with the outside on valve body.In the time that pressure reaches explosion requirement, cause rupture disk 6 explosions, gaseous state carries out safety dumping by the passage external tapping 7 that loses heart, and prevents tank body blast.
Content described in this specification embodiment is only enumerating of way of realization to inventive concept; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also and conceive the equivalent technologies means that can expect according to the utility model in those skilled in the art.
Claims (2)
1. aircraft cabin inside valve, comprise valve body, in described valve body, be provided with gaseous state passage, described gaseous state passage one end is provided with gaseous state passage external tapping, described valve body is provided with gaseous state control valve, it is characterized in that: described gaseous state passage connects a superpressure gaseous state passage, and described superpressure gaseous state passage connects a disappointing joint body, in described disappointing joint body, be provided with rupture disk, and described disappointing joint body end is provided with the disappointing passage external tapping being in communication with the outside.
2. aircraft cabin as claimed in claim 1 inside valve, is characterized in that: between described disappointing joint body and described rupture disk, be provided with sealing gasket.
