Description

Lightweight high-pressure oil pipe joint

Technical Field

The utility model relates to a pipe joint technical field, in particular to lightweight high pressure fuel pipe connects.

Background

Pipeline joint is a connecting line or adorns the part on components and parts with the pipeline, is the general name of the connecting piece that can install and remove in fluid passage, and the department of bending in the pipeline switching-over simultaneously also needs to connect through pipeline joint, as shown in fig. 1, for the pipeline joint design of the straight pipeline junction among the prior art, it adopts the direct integrated configuration design who leads to with the bend, and overall structure's assembly space is big, there is great loss of pressure, the input cost is higher, consequently the utility model develops a lightweight high pressure fuel pipe joint to solve the problem that exists among the prior art, through the retrieval, not discover with the utility model discloses same or similar technical scheme.

SUMMERY OF THE UTILITY MODEL

The utility model discloses the purpose is: the utility model provides a lightweight high pressure fuel pipe connects to solve among the prior art structural design assembly space of pipe joint big, have great pressure loss, the higher problem of input cost.

The technical scheme of the utility model is that: a light-weight high-pressure oil pipe joint comprises a joint body, a nut gasket and a baffle ring, wherein the nut, the nut gasket and the baffle ring are arranged on the joint body; the joint body comprises a first connecting end, a transition end and a second connecting end which are arranged in an integrated structure; the first connecting end, the transition end and the second connecting end are internally provided with a flow passage communicated with each other, the outer walls of the first connecting end and the second connecting end are both in a thread shape, the side wall of the middle part of the second connecting end is provided with an annular caulking groove, the nut gasket and the baffle ring are nested and matched at the caulking groove, and the nut is in threaded connection with the second connecting end and is positioned between the transition end and the caulking groove.

Preferably, the central axis of the first connecting end is perpendicular to the central axis of the second connecting end, the flow channel is arranged along the central axes of the first connecting end and the second connecting end respectively, and the flow channel in the transition end is in an 1/4 arc structure.

Compared with the prior art, the utility model has the advantages that:

the utility model adopts an integrated structural design mode, reduces the number of pipeline joints and the assembly times, and improves the assembly efficiency of a host factory; because the traditional two joints are changed into one joint, the cost is effectively reduced, the assembly space is reduced, and meanwhile, the structure is lighter; the pressure loss is reduced in the working process, the noise and the oil temperature are reduced, and the flow channel is smoother.

Drawings

The invention will be further described with reference to the following drawings and examples:

FIG. 1 is a schematic diagram of a prior art pipe joint;

fig. 2 is a schematic structural view of the pipe joint of the present invention;

fig. 3 is a cross-sectional view of the joint body of the present invention.

Wherein: 1. the joint comprises a joint body, 2, a nut, 3, a nut gasket, 4, a baffle ring, 5, a first connecting end, 6, a transition end, 7, a second connecting end, 8, a caulking groove, 9 and a flow channel.

Detailed Description

The following detailed description is made in conjunction with specific embodiments of the present invention:

as shown in fig. 2, the lightweight high-pressure oil pipe joint includes a joint body 1, a nut 2 mounted on the joint body 1, a nut washer 3, and a retainer ring 4.

As shown in fig. 3, the joint body 1 includes a first connection end 5, a transition end 6 and a second connection end 7 which are integrally formed; the outer walls of the first connecting end 5 and the second connecting end 7 are both in a thread shape, so that the connecting with a pipeline structure is convenient, and an annular caulking groove 8 is formed in the side wall of the middle part of the second connecting end 7; meanwhile, the central axis of the first connecting end 5 is perpendicular to the central axis of the second connecting end 7, and the transition end 6 is in an 1/4 flat columnar structure and is used for connecting the first connecting end 5 and the second connecting end 7; the first connecting end 5, the transition end 6 and the second connecting end 7 are internally provided with a flow passage 9 communicated with each other, the flow passage 9 is respectively arranged along the central axes of the first connecting end 5 and the second connecting end 7, and the flow passage 9 in the transition end 6 is in an 1/4 circular arc structure.

The nut gasket 3 and the baffle ring 4 are nested and matched at the caulking groove 8, the nut 2 is in threaded connection with the second connecting end 7 and is positioned between the transition end 6 and the caulking groove 8, and the nut gasket 3 is positioned between the nut 2 and the baffle ring 4.

The utility model adopts an integrated structural design mode, reduces the number of pipeline joints and the assembly times, and improves the assembly efficiency of a host factory; because the traditional two joints are changed into one joint, the cost is effectively reduced, the assembly space is reduced, and meanwhile, the structure is lighter; the pressure loss is reduced in the working process, the noise and the oil temperature are reduced, and the flow channel 9 is smoother.
