Abstract
The utility model discloses the rubber hose coupling that a kind of compression molding seals, wear including inner core mesopore and be connected with hose lining tube layer, hose lining tube layer outer end is connected with inner core end face by molding flange sulfidization molding；On the cylindrical of hose lining tube layer and close inner core outer end, cladding is connected with casing play, is connected with outer sebific duct layer on the surface of casing play outer end；By carrying out sealing for the first time by the sulfuration flange hose lining tube layer extruding locking that tip side connects in the face of inner core end face, and the hose lining tube layer that joint end face is provided with sealing ring and inner core end face upper overturning extrudes elastic deformation and carries out second time and seal, and tighten convex-concave tooth engaged that sleeve makes span in it be connected with successively by outer sebific duct layer end and casing play by extruding, corresponding with being spaced the concave-convex clutch tooth being connected with on inner core cylindrical withhold connected.Effectively increase hose lining tube layer and be connected the fastening power sealed with inner core.Manufacturing process is simple, and production efficiency improves；Extend the service life of rubber hose coupling, hence it is evident that reduce the production cost of user.
Description
Technical field
This utility model relates to the connection member of sebific duct；It is specifically related to the rubber hose coupling that a kind of compression molding seals.
Background technology
Rubber hose coupling on field drilling equipment in prior art, is the vitals connecting conveying high-pressure fluid.Raw
In product, described rubber hose coupling be typically with vulcanize integral sealing or withhold connect seal processing mode make.Shortcomings:
One be sulfuration integral sealing be injection curable adhesive layer in sleeve, its manufacturing process is complicated, and production efficiency is low.Two is to withhold connection
Sealing is to make its endoporus tighten by compression sleeve surface, the hose lining tube layer of body is withheld with inner core and is connected sealing.Used
Cheng Zhong, due to user, to deposit the rubber hose coupling time longer, and the fastening power that hose lining tube layer is connected with inner core at sealing easily relaxes.Work
Time, high pressure fluid then leaks out from the position that described fastening power is lax, shortens the service life of rubber hose coupling, time serious
Cause whole sebific duct to scrap, add the production cost of user.
Utility model content
The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of compression molding to seal
Rubber hose coupling, it is intended to realize manufacturing process simple, improves production efficiency, and increases the service life to become with the production reducing user
This.
For achieving the above object, the technical solution of the utility model is achieved in that the glue that this compression molding seals
Pipe joint, is connected body including inner core, joint and sleeve, inner core and sleeve；It is that inner core mesopore wears and is connected with hose lining tube layer,
Hose lining tube layer outer end is connected with inner core end face by molding flange sulfidization molding；In hose lining tube layer with outside inner core outer end
On circle, cladding is connected with casing play, is connected with outer sebific duct layer on the surface of casing play outer end；Joint upper ring cap is connected with sleeve, passes through
The connection of hub internal bore screw thread round thread outer with inner core fastens, and pulls tip side flange hose lining tube layer on inner core end face to squeeze
Pressure lock sealing；Hub internal bore is sleeved on the surface of outer sebific duct layer end and casing play, tightens sleeve inner end table by extruding
Face, the convex-concave tooth engaged making hub internal bore interval be connected with will be spaced on outer sebific duct layer end and casing play, and inner core cylindrical successively
The concave-convex clutch tooth correspondence being connected with is withheld connected.
Preferably, the flange hose lining tube layer crush seal being connected with it is provided with on sealing ring and inner core end face at joint end face.
Preferably, described casing play is connected and composed by steel wire or wirerope-winding.
This utility model takes said structure, by the sulfuration flange hose lining tube layer being connected with inner core end face by joint end face
Extruding locking carries out sealing for the first time, and the sealing ring being provided with by joint end face squeezes with the flange hose lining tube layer on inner core end face
Pressure carries out second time and seals, and tightens convex-concave tooth engaged that sleeve makes span in it be connected with successively by outer sebific duct layer by extruding
End and casing play, corresponding with being spaced the concave-convex clutch tooth being connected with on inner core cylindrical withhold connected.Effectively increase interior sebific duct
Layer is connected the fastening power sealed with inner core.Compared with the existing technology, manufacturing process is simple, and production efficiency improves；Extend sebific duct
The service life of joint, hence it is evident that reduce the production cost of user.
Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of embodiment of this utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, principle of the present utility model and feature are described in detail.Should illustrate: illustrated embodiment is only used
In explaining this utility model, do not constitute the concrete restriction to this utility model scope of patent protection.
The rubber hose coupling (shown in Fig. 1) that this compression molding seals, including inner core 4, joint 7 and sleeve 5, inner core and sleeve
Body is connected；It is that inner core 4 mesopore wears and is connected with hose lining tube layer 3, by extruding flange the sulfidization molding of mould, by described
Hose lining tube layer 3 outer end flange is connected with inner core 4 end face；The cylindrical of hose lining tube layer 3 and close inner core 4 outer end is coated with and is connected with
By the casing play 2 of steel wire winding, on the surface of casing play outer end, it is connected with outer sebific duct layer 1；Joint 7 upper ring cap is connected with sleeve 5,
Being fastened by the connection of hub internal bore screw thread with the outer round thread of inner core 4, one is to drive joint 7 end face to inner core 4 end face upper overturning
Hose lining tube layer 3 extruding locking, carry out First Contact Connections sealing (shown in Fig. 1).Two is to drive the sealing being connected with on joint 7 end face
Circle 6 extrudes with the hose lining tube layer 3 of inner core 4 end face upper overturning, carries out second time by the elastic deformation of sealing ring 6 and connects sealing
(shown in Fig. 1).Sleeve 5 inner hole sleeve is contained on the surface of outer sebific duct layer 1 end and casing play 2, tightens sleeve 5 inner end by extruding
Surface, makes the convex-concave tooth engaged that hub internal bore interval is connected with successively by outer sebific duct layer 1 end and casing play 2, with inner core 4 cylindrical
The concave-convex clutch tooth correspondence that interval is connected with withholds connected (shown in Fig. 1).Described casing play 2 can also be connected structure by wirerope-winding
Become.
The above is only preferred implementation of the present utility model.It is noted that, for the ordinary skill people of this area
Member, with essentially identical means, it is achieved essentially identical function, reaches essentially identical effect, it is not necessary to through creative work
