Abstract

The utility model relates to a hydraulic welding connector which comprises a welding guiding sleeve, a connecting ring and a flaring connector. One end of the welding guiding sleeve is fixedly connected with a hard pipe through a thread pair, a cone face is arranged at the other end of the welding guiding sleeve and is matched with an inner cone face of the flaring connector, the welding guiding sleeve is fixedly connected with the flaring connector through the connecting ring, and the other end of the flaring connector is connected with a hose pipe. The hydraulic welding connector has the advantages of being simple in structure, due to the fact that the number of connecting parts is decreased, sealing effect is good, and production cost is lowered.

Description

A kind of hydraulic pressure welded joint
Technical field
The utility model relates to a kind of hydraulic pressure welded joint.
Background technique
Welded joint in the well repairing machine hydraulic system, generally in hydraulic oil pipe connects, hard tube is in the transition of flexible pipe, hard tube must be selected transit joint for use with being connected of flexible pipe, sees Fig. 1, so just needs two joints, a welded joint 6 is welded on the hard tube, a jointing 7 connects flexible pipe, and this two hydraulic joints connection connects to compare with a joint has increased sealing, makes hydraulic oil liquid leak probability and increases.
Summary of the invention
For overcoming the deficiencies in the prior art, the purpose of this utility model provides a kind of hydraulic pressure welded joint, strengthens sealing, reduces parts.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of hydraulic pressure welded joint, comprise welding guide pin bushing, connecting ring, flare type joint, described welding guide pin bushing one end is fixedlyed connected with hard tube by screw pair, the other end is provided with the conical surface, inner conical surface coupling with flare type joint, the welding guide pin bushing is fixedlyed connected with flare type joint by connecting ring, and the flare type joint the other end is connected with flexible pipe.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, because the minimizing of connected element, good sealing effect reduces production costs.
Description of drawings
Fig. 1 is former welded joint structure schematic representation.
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1-flexible pipe 2-welding guide pin bushing 3-hard tube 4-connecting ring 5-flare type joint 6-welded joint 7-jointing.
Embodiment
Below in conjunction with Figure of description the utility model is described in detail, but should be noted that enforcement of the present utility model is not limited to following mode of execution.
See Fig. 2, a kind of hydraulic pressure welded joint, comprise welding guide pin bushing 2, connecting ring 4, flare type joint 5, described welding guide pin bushing 2 one ends are fixedlyed connected with hard tube 3 by screw pair, the other end is provided with the conical surface, with the inner conical surface coupling of flare type joint 5, welding guide pin bushing 2 is fixedlyed connected with flare type joint 5 by connecting ring 4, and flare type joint 5 the other ends are connected with flexible pipe 1.Welding guide pin bushing 2 and hard tube 3 welding, this design has not only reduced the quality of hydraulic element, has increased the Security of hydraulic system, and has reduced economic loss.
The utility model is simple in structure, owing to the minimizing of connected element, has not only reduced the quality of hydraulic element, has increased the Security of hydraulic system, good sealing effect, and reduced economic loss.
