The obturation effect of confined space, also, the check valve size in aircraft is different, when carrying out supply air line connection, it is necessary to
Using the supply air line of different sizes (such as diameter).
Utility model content
To solve the above-mentioned problems, the utility model proposes the connection structure of a kind of check valve and supply air line, solution
Certainly crossing cabin valve is installed on pressure bulkhead, and structure is influenced be subject to larger temperature, and can adapt to the shelf of different lower surfaces
Crossing cabin check valve.
The connection structure of the utility model check valve and supply air line, for through pressure bulkhead, and connects described unidirectional
Valve and supply air line, it is characterised in that including the shell with through hole, one end of the connection pressure bulkhead through hole of the shell is set
The first cover board to turn up is equipped with, one end of the direction check valve of the shell is provided with the second cover board of varus, described
Shell is connected by the first cover board with the pressure bulkhead, and the check valve is fixed at second cover board with supply air line
Both sides.
Preferably, second cover board is connected by screw with the check valve and supply air line.
Preferably, it is provided with the first packing ring between second cover board and the check valve.
Preferably, it is provided with second packing ring between second cover board and the supply air line.
Preferably, the first cover board is welded with the pressure bulkhead.
Preferably, the first cover board is integrally machined shaping with the pressure bulkhead.
The problem of the utility model solves crossing cabin valve on pressure bulkhead, and structure is influenced be subject to larger temperature.
Shelf crossing cabin check valve of the connection with different lower surfaces is adapted at the same time.
Brief description of the drawings
Fig. 1 is to show according to the structure of the utility model check valve and a preferred embodiment of the connection structure of supply air line
It is intended to.
Wherein, 1 is shell, and 2 be check valve, and 3 be supply air line, and 4 be screw, and 11 be the first cover board, and 12 be the second lid
Plate.
Embodiment
To make the purpose, technical scheme and advantage that the utility model is implemented clearer, below in conjunction with the utility model
Attached drawing in embodiment, is further described in more detail the technical scheme in the embodiment of the utility model.In the accompanying drawings, from beginning
Same or similar element is represented to same or similar label eventually or there is same or like element.Described reality
It is the utility model part of the embodiment to apply example, instead of all the embodiments.Below with reference to the embodiment of attached drawing description
It is exemplary, it is intended to for explaining the utility model, and it is not intended that limitation to the utility model.It is new based on this practicality
Embodiment in type, the every other implementation that those of ordinary skill in the art are obtained without creative efforts
Example, shall fall within the protection scope of the present invention.The embodiment of the utility model is described in detail below in conjunction with the accompanying drawings.
In the description of the utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", "front", "rear",
The orientation or position relationship of the instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outer " is based on attached drawing institutes
The orientation or position relationship shown, is for only for ease of description the utility model and simplifies description, rather than indicates or imply and is signified
Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality
The limitation of novel protected scope.
The utility model proposes the connection structure of a kind of check valve and supply air line, as shown in Figure 1, including with logical
The shell 1 in hole, one end of the connection pressure bulkhead through hole of the shell 1 are provided with the first cover board 11 to turn up, the court of the shell 1
The second cover board 12 of varus is provided with to one end of the check valve, the shell passes through the first cover board 11 and the pressure bulkhead
It is connected, the check valve 3 is fixed at the both sides of second cover board 12 with supply air line 2.
In the present embodiment, second cover board 12 is connected by screw with the check valve and supply air line.
It should be noted that under normal circumstances, along the ring through hole that is circumferentially provided with of the second cover board 12, check valve 2
Bottom is setback type compression piece, and has a ring through hole corresponding with above-mentioned through hole, equally, has what is turned up in supply air line 3
Plate face, and be also equipped with and an above-mentioned completely corresponding ring through hole, on vertical, the through hole phase of three structural members in the plate face
Mutually to it, it is fixed by screw 4,
For the seal of enhancing structure part connection, the is provided between second cover board 12 and the check valve
One packing ring；Second packing ring is provided between second cover board 12 and the supply air line.
In the present embodiment, the first cover board 11 is welded with the pressure bulkhead.In alternate embodiment, the first cover board 11 with it is described
Pressure bulkhead is integrally machined shaping, i.e., connection structure described in the utility model is integrally formed with the pressure bulkhead.Therefore can manage
Solve for the utility model by aircraft pressure bulkhead is carried out local prominent pressure bulkhead protrude surface, supply air line butting surface according to
The lower surface of shelf crossing cabin check valve is designed, and is bonded three surfaces, and be connected by screw.Solves crossing cabin valve peace
On pressure bulkhead, the problem of structure is influenced be subject to larger temperature.Shelf of the connection with different lower surfaces are adapted at the same time to wear
