Abstract

The utility model relates to a hydraulic system, in particular to a hydraulic pipeline. A hydraulic system pipeline connector comprises a pressure pipe, a hose, a compression nut, a sealing head and a pressure joint, wherein the front end of the pressure pipe is sheathed by the hose, the sealing head is sheathed on the host and has a conical seal fit with the pressure joint. The utility model is characterized in that two ends of the sealing head are provided with conical surfaces and openings. The utility model avoids special devices for production and the whole pressure pipe is not demanded to replaced when the conical head is damaged.

Description

A kind of hydraulic system pipe coupling

Technical field

The utility model relates to hydraulic system, relates in particular to hydraulic tubing.

Background technique

In the hydraulic plumbing system, spiral pipe joint is modal high pressure joint, general spiral pipe joint is made of pressure tube, gland nut and compression fittings at present, the pressure tube front end is the projection of kind of taper, cooperates with cone shape hole in the compression fittings, relies on gland nut to be screwed on the compression fittings, the conical head of pressure tube front end and the cone-shaped inner hole of compression fittings are held out against, nut revolves more inward, and conical surface is pressed tightly more, thereby prevents that high-pressure liquid from flowing out from fitting surface.The deficiency of this structure is that conical head and pressure tube are one, process with special device, if conical head destroys, then will change whole pressure tube.

Summary of the invention

The utility model is intended to solve the problems referred to above of existing pipe coupling, and a kind of hydraulic system pipe coupling is provided.The utility model need not special device processing, even conical head is impaired, also needn't change whole pressure tube.

A kind of hydraulic system pipe coupling comprises pressure tube, flexible pipe, gland nut, sealing head and compression fittings, and the pressure tube front end is with flexible pipe, and sealing head is enclosed within on the flexible pipe again, and sealing head is that kind of a cone seal cooperates with compression fittings.It is characterized in that the two ends of sealing head are conical surface, and be provided with opening.

Described a kind of hydraulic system pipe coupling is characterized in that flexible pipe is by rubber pipe or nylon tube.

The utility model is packed sealing head front end conical head on the compression fittings internal taper hole, and gland nut is spun on the compression fittings, revolves forward more, and the taper fit face is pressed tightly more, guarantees sealing; Simultaneously, the taper of gland nut screw root is pressed on the conical surface of sealing head rear end, form taper seal face structure, because the effect of opening, nut revolves forward more, the endoporus of sealing head is received more inward, and flexible pipe is embraced tightly on the external diameter of pressure tube, prevents that fluid from oozing out from the fitting surface of flexible pipe and sealing head fitting surface, flexible pipe and pressure tube.The beneficial effect of this structure is: flexible pipe and pressure tube all are kind of the most frequently used materials, do not need special equipment or special manufacturer to make, even the conical surface of sealing head destroys, also as long as make the sealing head again, do not need to change whole pressure tube, this sealing head is made simple, and general lathe for machining all can be made.

Description of drawings

Below, in conjunction with the accompanying drawings, further specify the utility model:

Fig. 1 is the utility model schematic representation;

Fig. 2 is described sealing head schematic representation.

Embodiment

As shown in Figure 1: a kind of hydraulic system pipe coupling, comprise pressure tube 4, flexible pipe 5, gland nut 6, sealing head 7 and compression fittings 3, pressure tube 1 front end is with flexible pipe 5, sealing head 7 is enclosed within on the flexible pipe 5 again, sealing head 7 is that kind of a cone seal cooperates with compression fittings 3, the two ends of sealing head 7 are conical surface, and are provided with opening 9.Described flexible pipe 5 is rubber pipe or nylon tube.

Claims (2)

1. a hydraulic system pipe coupling comprises pressure tube, flexible pipe, gland nut, sealing head and compression fittings, and the pressure tube front end is with flexible pipe, and sealing head is enclosed within on the flexible pipe again, and sealing head is that kind of a cone seal cooperates with compression fittings.It is characterized in that the two ends of sealing head are conical surface, and be provided with opening.
2, a kind of hydraulic system pipe coupling as claimed in claim 1 is characterized in that, flexible pipe is by rubber pipe or nylon tube.
