Abstract
The high-pressure rotary joint comprises a central shaft, a shell, a base, an axial bearing, a radial bearing and a base reducing diameter, wherein the base is fixed in the shell, the central shaft penetrates through the shell and is fixedly connected with the front part of the base through the axial bearing and the radial bearing, a water seal gland is installed between the central shaft and the base, and the base reducing diameter is connected with the rear part of the base. The utility model discloses a split type dismantlement structure has eliminated traditional rotary joint surface weld, has avoided welding seam department to leak the problem, and the center pin passes through axial bearing and journal bearing can arbitrary axial operation, and simple structure, use are convenient, and the operation is stable, have the advantage that production efficiency is high and low in production cost.
Description
Technical Field
The utility model relates to a fluid conveying pipeline accessory technical field, concretely relates to high-pressure rotary joint.
Background
Along with the soaring of the economy of China, the industrial cleaning industry is also developed vigorously as an important component of the industrial economy of China. The data show that in 2011, only China industrial cleaning equipment and industrial cleaning agent markets reach 200 billion yuan. Industrial cleaning is a process in which a contaminated layer or coating formed by physical, chemical or biological action on the surface of an object is called fouling, and a process in which the contaminated layer or coating is removed to restore the original surface condition is called cleaning. Along with the acceleration of our country reform development and modernization construction pace to and the enhancement of national people to environmental protection consciousness, high pressure water jet cleaning technology has that the washing is fast, the cleaning performance is good and can not produce secondary pollution after wasing, accepted by more and more enterprises, domestic high pressure water wash pipe adopts the joint all to adopt fixed connection at present, bearing strength is low, because high pressure water wash well high-pressure pipe can not be crooked, the stress ratio that the joint body part received is great, the pipe explosion that very easily takes place after the high pressure pipe is crooked causes personnel's injury, and the operation is inconvenient.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high pressure rotary joint to solve the difficult problem of dismantling to connect and connect body stress concentration and influence greatly and connect life that prior art exists.
The utility model provides a technical scheme that its technical problem adopted is:
a high-pressure rotary joint comprises a central shaft, a shell, a base, an axial bearing, a radial bearing and a base reducing diameter, wherein the base is fixed in the shell, the central shaft penetrates through the shell to be fixedly connected with the front portion of the base through the axial bearing and the radial bearing, a water seal gland is installed between the central shaft and the base, and the base reducing diameter is connected with the rear portion of the base.
And an oil seal is arranged at the joint of the central shaft and the end part of the shell.
The reducing joint of the base and the base is provided with an oil seal.
The utility model discloses when high pressure rotary joint used, on being connected to center pin and base reducing respectively with the high-pressure line, high-pressure cleaning water is by the base reducing through base flow direction center pin, under high pressure water pressure, the center pin passes through axial bearing and the arbitrary axial operation of radial bearing can corresponding rivers pressure direction.
The utility model discloses a split type dismantlement structure has eliminated traditional rotary joint surface welding seam, has avoided welding seam department to leak the problem, and the center pin passes through axial bearing and journal bearing can arbitrary axial operation, and simple structure, use are convenient, and the operation is stable, has the advantage that production efficiency is high and low in production cost.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, the central shaft 1, the shell 2, the water seal gland 3, the base 4, the oil seal 5, the axial bearing 6, the radial bearing 7, the oil seal 8 and the base 9 are variable in diameter.
Detailed Description
As shown in the figure, the high-pressure rotary joint is composed of a central shaft 1, a shell 2, a base 4, an axial bearing 6, a radial bearing 7 and a base reducing 9, wherein the base 4 is fixed in the shell 2, the central shaft 1 penetrates through the shell 2 and is fixedly connected with the front part of the base 4 through the axial bearing 6 and the radial bearing 7, a water seal gland 3 is installed between the central shaft 1 and the base, and the base reducing 9 is connected with the rear part of the base 4. An oil seal 5 is arranged at the joint of the central shaft 1 and the end part of the shell 2. An oil seal 8 is arranged at the joint of the base 4 and the base reducing 9.
The utility model discloses when high pressure rotary joint used, on being connected to center pin and base reducing respectively with the high-pressure line, high-pressure cleaning water is by the base reducing through base flow direction center pin, under high pressure water pressure, the center pin passes through axial bearing and the arbitrary axial operation of radial bearing can corresponding rivers pressure direction.
