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.
In prior art, generally adopt the spiral connection of bolt for the docking of high-pressure oil pipe, 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 oil connection that can shake at height the lasting running in place.
Summary of the invention
the problem that 1, will solve
The spiral connection of general employing bolt while connection 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 utility model 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, still can work lastingly in vibrations place.
2, technological scheme
For addressing the above problem, the utility model adopts following technological scheme.
A kind of 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, the beneficial effects of the utility model are:
(1) the utility model head 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, still can work lastingly in vibrations place;
(2) in the utility model, 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 utility model is simple in structure, easy to operate, is easy to manufacture.
