The beneficial effects of the invention are as follows：The application is by setting a set of barrel surface sealing system to be mutually inserted the gold of connection
Belong to and being sealed between flexible pipe and rotary spray gun transition conduit by described barrel surface sealing system.Lead in the prior art so as to overcome
Chang Jun is lacked using long-term, high pressure, the material leakage for frequently rotating and occurring, quick abrasion etc. existing for the sealing structure of end face seal
Fall into.Due between metal hose and rotary spray gun transition conduit by barrel surface that contact surface is more many times greater than end face seal contact surface
Sealing system is sealed, so as to effective on the premise of identical operating pressure, identical rotary speed and identical speed
Raising sealing effectiveness, extend the service life of sealing surface.
It is further accommodating chamber to be provided with the connection end of the rotary spray gun transition conduit, in the metal hose
Connection end on be socketed with sealing shroud, described barrel surface sealing system by mutual expanded joint the accommodating chamber axially inner side wall
Formed with the axially outer side of the sealing shroud.
Such scheme it is preferable that, described sealing shroud includes packing ring and graphite packing, described in alternate socket
The packing ring on the connection end of metal hose forms described sealing shroud with the graphite packing.
It is further that described Hermetical connecting structure also includes installation transition spool piece, described accommodating chamber is arranged on institute
In the installation transition spool piece stated, installation cavity, described installation transition are provided with the connection end of the rotary spray gun transition conduit
Sleeve pipe is packed in described installation cavity.
Such scheme it is preferable that, described Hermetical connecting structure also includes crimp, is socketed the metal hose
Connection end on sealing shroud be pressed on by described crimp in described accommodating chamber.
It is further that described crimp includes gland and fixing bolt, described sealing shroud passes through described gland
It is pressed under the cooperation of the fixing bolt in described accommodating chamber.
It is further that described Hermetical connecting structure also includes end face gasket, described end face seal pad is arranged in institute
On the end face for stating the installation transition spool piece in installation cavity.
Brief description of the drawings
Fig. 1 is that the present invention is used for the three-dimensional exploded perspective view that molten iron rotates the Hermetical connecting structure of desulfurization rifle.
In figure mark for：Metal hose 1, rotary spray gun transition conduit 2, accommodating chamber 4, sealing shroud 5, packing ring 6, graphite packing
The 7th, transition spool piece 8, installation cavity 9, crimp 10, gland 11, fixing bolt 12, end face gasket 13 are installed.
Embodiment
It is a kind of sealing effectiveness provided by the invention as shown in Figure 1, the molten iron that is used for of service life length rotates desulfurization rifle
Hermetical connecting structure.Described Hermetical connecting structure includes metal hose 1 and rotary spray gun transition conduit 2, described sealed connection
Structure also includes barrel surface sealing system, is mutually inserted between the metal hose 1 of connection and rotary spray gun transition conduit 2 by described
Barrel surface sealing system sealing.The application is by setting a set of barrel surface sealing system to be mutually inserted the metal hose of connection
Sealed between 1 and rotary spray gun transition conduit 2 by described barrel surface sealing system.So as to overcome in the prior art typically each
The defects of using long-term existing for the sealing structure of end face seal, high pressure, the material leakage for frequently rotating and occurring, quick abrasion.By
It is close by the contact surface barrel surface more many times greater than end face seal contact surface between metal hose 1 and rotary spray gun transition conduit 2
