Abstract

The fitting terminates an end of a high-pressure hose and comprises a coupling having a portion thereof inserted in the hose end, and a sleeve, enveloping both the hose end and the coupling inserted portion, crimped onto the hose end. A void obtains within the sleeve at the end of the hose, and a capillary hole formed in the sleeve (and in a circumferential wall of the coupling) communicates the void with the external surface of the sleeve. The hole, a weep hole, safely relieves fluid leakage or seepage from the void.

Description

High-pressure end fitting for soft pipe
The present invention relates to be used for the link or the pipe joint of high pressure hose and similar pipe.Particularly relate to a kind of high pressure hose and joint.
Such joint involved in the present invention generally includes a rugosity sleeve pipe on hose end, and a part with ribbing is arranged on this hose end.
Usually, when flow of liquid is crossed joint, the thing that does not have trouble takes place, but the circulation of working as liquid is obstructed or is blocked, and in some position of upstream, the static pressure of fluid will attempt to seek the approach of leakage in the joint, as recurrent situation, if liquid can penetrate between sleeve pipe and the hose end, sleeve pipe just will break, and perhaps sleeve pipe loosens the grip force of flexible pipe and comes off.
The objective of the invention is to propose a kind of improved high pressure hose and pipe joint, can eliminate the existing problem of aforementioned existing joint greatly.
The objective of the invention is to disclose a kind of high-pressure hose end connector especially, it comprises the flexible pipe that has the end, hose connector and rugosity sleeve pipe, wherein said link has first support arm that holds flexible pipe, outer second support arm that connects, with the annular land that is connected said two support arms, first support arm is contained in the end of flexible pipe, and the end of first support arm and flexible pipe all is contained in the rugosity sleeve pipe, the rugosity end of said rugosity sleeve pipe at flexible pipe, land and hose end have surface spaced apart from each other, and they have formed the inner chamber of the two, and joint of the present invention also comprises the device in order to communication with cavity and bushing outer surface.
Except these new features, by the argumentation that following accompanying drawing is done, further aim of the present invention will find out more significantly that accompanying drawing is the longitudinal cross-section view of the high-pressure hose end connector of an example of the present invention.
As shown in the figure, joint 10 comprises flexible pipe part 12, and it has end 14, also comprises hose connector 16, and link 16 has the first rib shape support arm 18 of admitting flexible pipe at the one end, connects support arm 20 outside the relative the other end has.Integrated disc portions 22 connects said two support arms 18 and 20, and sleeve pipe 24 contains hose end 14 and arm 18 and is crimped onto on the end 14.
Integrated disc portions 22 has a flat platform 26 and an annular wall 28 of stretching out along platform 26 peripheries, annular wall 28 is enclosed within the sleeve pipe 24, one inner chamber 30 is arranged between the end 14 of platform 26 and flexible pipe 12, if pressured fluid leaks into inner chamber 30, be seeped into then between pipe end 14 and the annular wall 28, be seeped between pipe end 14 and the sleeve pipe 24, this will make the sleeve pipe generation break again, and the sleeve pipe on the flexible pipe is become flexible so that generation comes off.
According to my invention, a pore 32 is set, pass annular wall 28 and sleeve pipe 24, so that discharge any hydrostatic pressure that may form, hole 32 provides a kind of controlled orientation to leak, purpose is to make the integrity of joint unaffected.
Although be the invention of discussing me with special example in person, be readily appreciated that this only is to illustrate and not as the qualification of the scope of the invention, as in goal of the invention with to be attached to the following claim book represented.

Claims (2)

1, a kind of high-pressure hose end connector that has flexible pipe, comprise hose end, hose connector and rugosity sleeve pipe, wherein link has first support arm and outer second support arm that is connected of admitting flexible pipe, and the annular land that connects said two support arms, first support arm is contained in the end of flexible pipe, first support arm and hose end are contained in the rugosity sleeve pipe, rugosity casing pipe sleeve is on hose end, annular land and hose end have the surface of space, between the two, form inner chamber, it is characterized in that being provided with the pore that passes sleeve pipe and annular land and lead to inner chamber.
2, according to the said high-pressure hose end connector of claim 1, it is characterized in that land comprises that flat basically platform reaches the peripheral extended annular wall from platform, rugosity sleeve pipe has the cylindrical wall that suit the land annular wall.
