Description

With the rubber hose coupling of Expansion sealing circle
Technical field
the utility model relates to the connected element of sebific duct; Be specifically related to a kind of rubber hose coupling with Expansion sealing circle.
Background technique
rubber hose coupling in prior art on field drilling equipment connects drilling equipment to carry out the vitals of fluid conveying, and its structure comprises the seal groove that the cylindrical of the endoporus of sleeve, core bar is connected with, and is connected accordingly with the cylindrical of sebific duct, endoporus sleeve.The endoporus working pressure of usual described sebific duct is less than 30Mpa.When the endoporus working pressure of sebific duct is greater than 30Mpa, described rubber hose coupling then has the following disadvantages: one be have because of rubber material tighten up the easily loose characteristic of stress, when rubber hose coupling is under wild environment badly and higher temperature during operation, often because the phenomenon tightening up stress relaxation appears in seal groove joint on the glue-line of sebific duct endoporus and core bar cylindrical, sealability is caused to decline, under the working pressure that sebific duct endoporus is higher, there is fluid leaks, reduce the working life of rubber hose coupling.Two is user's connection needs according to drilling equipment, in the core bar outer end of described rubber hose coupling, welding is connected with the Pipe moveable joint being convenient to installing/dismounting, the high temperature that welding produces conducts to inner end by the outer end of described core bar, the temperature of described core bar inner end cylindrical is caused to raise, make to tighten up power with the glue-line temperature distortion of sebific duct endoporus joint loose, the fluid of work Intermediate High Pressure, occur that position that the power that tightens up is loose is to external leakage by seal groove joint on sebific duct endoporus glue-line and core bar cylindrical, cause whole sebific duct to scrap, significantly increase cost of production.
Model utility content
for the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of rubber hose coupling with Expansion sealing circle, is intended to the cost of production improving working life and reduce user.
for achieving the above object, the technical solution of the utility model is achieved in that this rubber hose coupling with Expansion sealing circle, comprises the seal groove that the cylindrical of the endoporus of sleeve, core bar is connected with, and is connected accordingly with the cylindrical of sebific duct, endoporus sleeve; It is at least connected with a fixed groove on the inner end core bar cylindrical being positioned at described seal groove; Core bar cylindrical upper ring cap bottom fixed groove is connected with the endoporus of seal ring, the cylindrical of described seal ring connects with the glue-line elastic packing of sebific duct endoporus, be provided with toroidal cavity in the side of seal ring, the opening of this toroidal cavity is towards the joint of core bar cylindrical front end and sebific duct endoporus.
preferably, the structure of described seal ring is y-type seal ring.
preferably, described seal ring is the wherein one that rubber and plastic, rubber and polyurethane materials are formed.
the utility model is by taking said structure, in work, glue-line when core bar cylindrical front end and sebific duct endoporus joint occurs tightening up the fluid that stress relaxation produces gap leakage, enter in the toroidal cavity of seal ring side on core bar cylindrical, under the effect of high pressure fluid, the outer round surface of crush seal circle seals with the glue-line elastic expansion of sebific duct endoporus and connects, and eliminates the gap between core bar cylindrical and sebific duct endoporus glue-line, effectively prevent fluid leaks.Compared with the existing technology, significantly improve the working life of rubber hose coupling and reduce the cost of production of user.
Accompanying drawing explanation
fig. 1 is the partial sectional view of a kind of embodiment of the utility model.
Embodiment
below in conjunction with accompanying drawing, principle of the present utility model and feature are described in detail.Should illustrate: illustrated embodiment, only for explaining the utility model, does not form the concrete restriction to the utility model scope of patent protection.
this rubber hose coupling with Expansion sealing circle, comprises the seal groove 3 that the cylindrical of the endoporus of sleeve 2, core bar 1 is connected with, and is connected accordingly with the cylindrical of sebific duct 5, endoporus sleeve; It is that interval is connected with two fixed grooves on inner end core bar 1 cylindrical being positioned at described seal groove 3; On core bar cylindrical bottom described fixed groove, ring set is connected with the endoporus of y-type seal ring 4 respectively, the cylindrical of described y-type seal ring connects with the glue-line elastic packing of sebific duct 5 endoporus, be provided with toroidal cavity in the side of y-type seal ring 4, the opening of this toroidal cavity is towards the joint (shown in Fig. 1) of core bar 1 cylindrical front end and sebific duct endoporus.Described y-type seal ring is made up of rubber material.Certainly, according to different designing requirements, described seal ring can also be made up of rubber and plastic or polyurethane materials.
when the utility model is installed and connected, first the cylindrical of sebific duct 5, endoporus are connected with the cylindrical of core bar 1 by the endoporus of sleeve 2 accordingly.Pass through crimping equipment, respectively by sleeve 2 cylindrical and the cylindrical of the sebific duct 5 being connected with steel wire floor being placed in this hub internal bore, and the diameter of sebific duct endoporus glue-line, the extruding contraction that stretches gradually diminishes, by the glue-line of the steel wire floor on sebific duct 5 cylindrical and sebific duct endoporus, the extruding of close and firm ground enters and sleeve 2 bore area tightens up groove respectively, and on the outer round surface of two y-type seal rings 4 at seal groove 3 on core bar 1 cylindrical and interval, make the cylindrical of described seal ring 4 be connected (shown in Fig. 1) with the glue-line elastic packing of sebific duct 5 endoporus.
when rubber hose coupling is under wild environment badly and higher temperature during operation, there is tightening up (shown in Fig. 1) when stress relaxation produces the gap of leak fluid in the glue-line of core bar 1 cylindrical front end and sebific duct 5 endoporus joint, the high pressure fluid of sebific duct endoporus, along the outside seepage in gap between core bar cylindrical and sebific duct endoporus glue-line, enter in the toroidal cavity of first y-type seal ring 4 side on the cylindrical of core bar front end, the principle equal everywhere according to seal container fluid pressure, enter the pressure that the leak fluid in described toroidal cavity produces, the extruding outer round surface of first y-type seal ring 4 seals with the glue-line elastic expansion of sebific duct endoporus and connects, sealing is tightened up to the gap existed between core bar cylindrical and sebific duct endoporus glue-line.When the fluid in the toroidal cavity entering first y-type seal ring 4 side continues outside seepage, the fluid of seepage enters along described gap in the toroidal cavity of second y-type seal ring side on the cylindrical of core bar front end, the outer round surface of pressure continuation extruding second y-type seal ring that high-pressure liquid produces seals with the glue-line elastic expansion of sebific duct 5 endoporus and connects, again sealing is tightened up to the gap existed between core bar 1 front end cylindrical and sebific duct endoporus glue-line, completely eliminate the gap existed between core bar cylindrical and sebific duct endoporus glue-line, prevent the seepage (shown in Fig. 1) of fluid.
the above is only preferred implementation of the present utility model.Be noted that for those of ordinary skill in the art; with substantially identical means; realize substantially identical function; reach substantially identical effect; without the need to other technical characteristics just obviously associated through creative work; can also replace the modification and/or improvement of making several basic same way, these changes should be considered as equivalent feature, within the protection domain all belonging to the utility model patent.
