According to the high-pressure oil tube joint, an oil tube is fixed in the joint through a special internal structure, the ring flange structure can be used for fixing permanently, and the periphery of a ring flange is fastened through bolts, so that the stress on the oil tube is uniform, and the high-pressure oil tube joint can work for a long time on a vibration occasion.
Description
Technical field
The present invention relates to a kind of pipe-line equipment, relate in particular to a kind of high-pressure oil pipe joint.
Background technique
High-pressure oil pipe is generally used for the fields such as excavator, loader, side dumper, hydraulic booster, hydraulic support, cement pipe, agricultural irrigation sebific duct, engineering mechanical hydraulic oil pipe, the conveying of seabed natural gas, oil transportation.And on these equipment, high-pressure oil pipe often need to bear very large vibrations, thereby easily cause high-pressure oil pipe joint place oil accident, and high-pressure oil pipe is connecting high pressure oil pump and oil-injection machine, belong to fuel injection system, act on very importantly, and high-pressure oil pipe can bear the high pressure up to 150MPa, abnormal vibrations can cause huge loss, also have very large disaster hidden-trouble.
Docking for high-pressure oil pipe in prior art generally adopts the spiral connection of bolt, in oil pipe vibrations process, the outside thread of bolt is easy to wear, and joint is easily loosening, thereby cause oil accident, so need to provide a kind of, can shake at height the oil connection of the lasting running in place.
Summary of the invention
the problem that 1, will solve
The spiral connection of general employing bolt while connecting for existing high-pressure oil pipe, and high-pressure oil pipe is used in the place that vibrations are larger, bolt internal thread is easy to wear, and joint is easily loosening, thereby causes the problem of oil accident, the invention provides a kind of high-pressure oil pipe joint, it is fixed on oil pipe in joint by special internal structure, is provided with again flange plate structure and plays lasting fixation, finally by bolton flange plate surrounding, make oil pipe stressed evenly, in vibrations place, still can work lastingly.
2, technological scheme
For addressing the above problem, the present invention adopts following technological scheme.
A high-pressure oil pipe joint, comprises joint body, and described joint body one end is flange plate structure; Described flange plate structure surrounding is evenly distributed with N mounting hole, and middle part is provided with manhole; Described joint body inside is stepped, and from the one end away from flange plate structure, is followed successively by the first hollow section, the second hollow section, the 3rd hollow section; Described the first hollow section, the 3rd hollow section are column, and the second hollow section is round table-like, and second hollow section one end diameter equates with the first hollow section, and the other end diameter equates with the 3rd hollow section; The ratio of the height of described the first hollow section, the second hollow section, the 3rd hollow section is 2:1:3.
Preferably, diameter and the 3rd hollow section equal diameters of the manhole at described flange plate middle part.
Preferably, the value of the quantity N of the equally distributed mounting hole of described flange plate structure surrounding is: 4≤N≤8.
More preferably, the quantity of the equally distributed mounting hole of described flange plate structure surrounding is 6.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
(1) the present invention body one end is flange plate structure; Described flange plate structure surrounding is evenly distributed with N mounting hole, and middle part is provided with manhole, flange plate structure plays lasting fixation, finally passes through in mounting hole place bolton flange plate surrounding, make oil pipe stressed evenly, in vibrations place, still can work lastingly;
(2) in the present invention, inside is stepped, and from the one end away from flange plate structure, is followed successively by the first hollow section, the second hollow section, the 3rd hollow section; Described the first hollow section, the 3rd hollow section are column, the second hollow section is round table-like, the ratio of the height of described the first hollow section, the second hollow section, the 3rd hollow section is 2:1:3, adopt special like this internal structure, can guarantee when oil pipe inserts accurately to locate at the second hollow section place, and because second hollow section one end diameter equates with the first hollow section, the other end diameter equates with the 3rd hollow section, can make oil connection place pressure suitably reduce.
(3) the present invention is simple in structure, easy to operate, is easy to manufacture.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention;
Fig. 2 is left view of the present invention.
Number in the figure explanation: 1, joint body; 2, the first hollow section; 3, the second hollow section; 4, the 3rd hollow section; 5, manhole; 6, mounting hole; 7, flange plate structure.
Embodiment
For further understanding content of the present invention, below in conjunction with Figure of description and specific embodiment, describe the present invention.
As shown in Figure 1 and Figure 2, a kind of high-pressure oil pipe joint, comprises joint body 1, and described joint body 1 one end is flange plate structure 7; Described flange plate structure 7 surroundings are evenly distributed with N mounting hole 6, and middle part is provided with manhole 5; Described joint body 1 inside is stepped, and from the one end away from flange plate structure 7, is followed successively by the first hollow section 2, the second hollow section 3, the 3rd hollow section 4; Described the first hollow section 2, the 3rd hollow section 4 are column, and the second hollow section 3 is round table-like, and second hollow section 3 one end diameters equate with the first hollow section 2, and the other end diameter equates with the 3rd hollow section 4; The ratio of the height of described the first hollow section 2, the second hollow section 3, the 3rd hollow section 4 is 2:1:3.
In addition, diameter and the 3rd hollow section 4 equal diameters of the manhole 5 at described flange plate middle part.
As a kind of optimal way, the quantity N=6 of the equally distributed mounting hole 6 of described flange plate structure 7 surrounding.
During use, directly high-pressure oil pipe is inserted in oil connection, by the second hollow section 3 places, accurately locate, and because second hollow section 3 one end diameters equate with the first hollow section 2, the other end diameter equates with the 3rd hollow section 4, can make oil connection place pressure suitably reduce, and finally adopts the blue dish of bolt and hanger in place structure 7, make oil pipe in the stable docking of oil connection, guarantee, at the large oil connection place, place of vibrations, oil accident does not still occur.
