Abstract
The invention relates to a diaphragm assembly. The diaphragm assembly comprises a rupture diaphragm, a gasket and a grate. The outer diameter of the gasket is smaller than that of the grate. The gasket is designed with a blind hole. The rupture diaphragm is designed with a protrusion block. When the diaphragm assembly is assembled, the protrusion block on the rupture diaphragm is embedded into the blind hole of the gasket, and one side provided with a nick, of the rupture diaphragm is fitted to the grate. When the diaphragm assembly is mounted, the grate is connected to a flange on the upstream side of the air flow. The diaphragm assembly is made of a pure copper diaphragm and accordingly has good compatibility with high-temperature and high-speed oxygen. The fail-proof design is used for ensuring that the rupture diaphragm is not mounted reversely when the diaphragm assembly is assembled and the diaphragm assembly is not reversely mounted in a pipe.
Description
Technical field
The present invention relates to a kind of diaphragm unit, particularly relate to the diaphragm unit that a kind of carrier rocket liquid oxygen tank Autogeneous pressurization is used.
Background technique
Diaphragm unit is carrier rocket pressurizing transmission system important unit used, and its effect relies on diaphragm unit liquid oxygen tank and pressurization system to be separated before an engine is started, upon actuation, makes rupture of diaphragm, to tank supercharging by the effect of pressurization gas pressure.
The known diaphragm unit that existing pressurizing transmission system is used, the rupture disc material in diaphragm unit is fine aluminium sheet material, washes away lower fine aluminium diaphragm and there is at high temperature, high speed oxygen the hidden danger producing spark and detonation.
In diaphragm unit, the one side that shelves grid and packing ring contact with rupture disc is plane structure.When diaphragm unit assembles, there is the possibility that rupture disc direction is anti-loaded.If rupture disc direction is anti-loaded, under working pressure, rupture disc cannot beam fracture, and diaphragm unit is installed in pipeline not decompose and also cannot checks, adaptability, reliability, security requirement when can not meet work completely.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the object of the present invention is to provide a kind of diaphragm unit held with high temperature, high speed oxygen gas phase.The present invention takes the technological scheme using fine copper diaphragm, can the intrinsic defect of combustion explosion to solve that existing diaphragm unit works under high temperature, high speed oxygen, and has anti-mounted design, thus improves diaphragm unit adaptability, reliability, Security.
In order to reach foregoing invention object, the invention provides a kind of diaphragm unit, comprising: rupture disc, packing ring, fence.Described washer outer diameter is less than fence external diameter, and described packing ring is designed with blind hole, and described rupture disc is designed with projection.During described diaphragm unit assembling, the projection on rupture disc embeds in the blind hole of packing ring, and rupture disc indentation side and fence are affixed.When described diaphragm unit is installed, fence and side, air-flow upstream Flange joint.
The present invention compared with prior art has the following advantages:
Select fine copper diaphragm, have good compatibility with high temperature, high speed oxygen; Take error-preventive design place to execute, rupture disc can not be anti-loaded when assembling to ensure that diaphragm unit, and diaphragm unit also can not be anti-loaded when being installed in pipeline.
Accompanying drawing explanation
By reading the detailed description done non-limiting example done with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:
Fig. 1 is the structural representation of a kind of diaphragm unit of the present invention.
Embodiment
See the accompanying drawing that the embodiment of the present invention is shown, hereafter in more detail the present invention will be described.But the present invention can realize in many different forms, and should not be construed as by the restriction in the embodiment of this proposition.On the contrary, it is abundant and complete open in order to reach for proposing these embodiments, and makes those skilled in the art understand scope of the present invention completely.In these accompanying drawings, for clarity sake, may be exaggerated size and the relative size in layer and region.
Now by describing in detail according to preferred embodiment of the present invention, to be further elaborated the present invention.
Figure 1 shows that the structural representation of a kind of diaphragm unit of the present invention, this diaphragm unit comprises rupture disc 1, packing ring 2, fence 3.Packing ring 2 external diameter is less than fence 3 external diameter, and packing ring 2 is designed with square blind hole; Rupture disc 1 is designed with horseshoe type indentation, has projection in rupture disc 1 edge designs, projection direction is towards rupture disc 1 without indentation side, and rupture disc 1 selected materials is the thick fine copper sheet material of 0.5mm; During diaphragm unit assembling, the projection on rupture disc 1 embeds in the blind hole of packing ring 2, and rupture disc 1 indentation side and fence 3 are affixed; When diaphragm unit is installed, fence 3 and side, air-flow upstream Flange joint.When rupture disc 1 positive pressure reaches cracking pressure, complete the breaking of horseshoe type indentation realizes pipeline connection, by fence 3 load, realizes rupture disc 1 and oppositely can bear elevated pressures and do not break.
Owing to adopting technique scheme, a kind of diaphragm unit provided by the invention has such beneficial effect: select fine copper diaphragm, has good compatibility with high temperature, high speed oxygen; Take error-preventive design place to execute, rupture disc can not be anti-loaded when assembling to ensure that diaphragm unit, and diaphragm unit also can not be anti-loaded when being installed in pipeline.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.
