Abstract
The invention discloses a kind of space flight hermetically sealed can flanges, an inlet port and an outlet are provided on the side wall of hollow cavity, the top of hollow cavity is also provided with a gathering hole, connection one enters pipe on inlet port, a first flange disk is connected into the end of pipe, outlet is equipped with a second flange disk, gathering hole is equipped with a third ring flange, a lid is flexibly connected on third ring flange, the inside of gathering hole is equipped with a holder, holder is equipped with a spring shaft, a compression bar is fixedly connected on spring shaft, a sealing cover is fixedly connected on compression bar, sealing cover elasticity is pressed against on inlet port.The flange is provided with a hollow cavity on the body, it is pressed against on inlet port provided with a sealing cover elasticity in cavity, accordingly even when minor leakage fluid, which occurs, for the valve body on inlet port will not leak into discharge pipe at once, sealing cover provides secondary sealing function, safety higher.It opens head cover to repair sealing mechanism from gathering hole, operation is more convenient.
Description
Technical field
The present invention relates to a kind of space flight hermetically sealed can flanges.
Background technology
Flange is called flange flange disk or flange.Flange is the part being connected with each other between axis and axis, between pipe end
Connection；Also have with the flange imported and exported in equipment, the connection being used between two equipment, such as speed reducer flange.Flange connects
It connects or bump joint, refers to the releasable connection being connected with each other by flange, gasket and bolt three as one group of combined sealing structure.
Space flight hermetically sealed can one kind that flange is flange, current this flange itself does not simultaneously have multi-sealing function, when space flight seals
Tank cannot provide sealing and ensure when there is leakage accident, safety is not high.
Invention content
The present invention is mainly the technical problem solved present in the prior art, to provide a kind of space flight hermetically sealed can usage
It is blue.
The above-mentioned technical problem of the present invention is mainly to be addressed by following technical proposals：
A kind of space flight hermetically sealed can flange is provided with an inlet port and one including a hollow cavity on the side wall of the hollow cavity
Outlet, the top of the hollow cavity are also provided with a gathering hole, on the inlet port connection one enter pipe, it is described into pipe
End connects a first flange disk, and the outlet is equipped with a second flange disk, and the gathering hole is equipped with a third flange
Disk is flexibly connected a lid on the third ring flange, and the lid is fixedly connected by a screw rod with third ring flange, described
The inside of lid is equipped with a diaphragm seal, and the top of the lid is equipped with a hoisting ring, and the inside of the gathering hole is equipped with a holder,
The holder is equipped with a spring shaft, is fixedly connected with a compression bar on the spring shaft, a sealing cover is fixedly connected on the compression bar,
The sealing cover elasticity is pressed against on inlet port.
As preferred embodiments of the present invention, the compression bar is connected between sealing cover by screw rod.
As preferred embodiments of the present invention, the sealing cover is stainless steel cover.
The space flight hermetically sealed can of present invention flange is provided with a hollow cavity on the body, and cavity is interior close provided with one
Capping elasticity is pressed against on inlet port, accordingly even when minor leakage fluid, which occurs, for the valve body on inlet port will not leak into row at once
Outlet pipe, sealing cover provide secondary sealing function, safety higher.Head cover is opened to tie up sealing mechanism from gathering hole
It repaiies, operation is more convenient.
Description of the drawings
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
Obtain other attached drawings according to these attached drawings.
Fig. 1 is the structural schematic diagram of the space flight hermetically sealed can flange of the present invention.
Specific implementation mode
The preferred embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
As shown in Figure 1, a kind of space flight hermetically sealed can flange 1, including a hollow cavity 4, on the side wall of the hollow cavity 4
It is provided with an inlet port 3 and an outlet 5, the top of the hollow cavity 4 is also provided with a gathering hole 8, is connected on the inlet port 3
