Abstract
The utility model discloses a high-pressure connection oil pipe which comprises a high-pressure rubber pipe, a high-pressure steel pipe, a pressure pipe sleeve and a connection nut, wherein the connection nut is clamped at the pipe socket connection end of the high-pressure steel pipe; the other end of the high-pressure steel pipe is sleeved in the high-pressure rubber pipe; the sleeving end of the high-pressure rubber pipe is sleeved with the pressure pipe sleeve; the annular bottom of the pressure pipe sleeve is sleeved on the high-pressure steel pipe; one end of the pressure pipe sleeve close to the annular bottom is provided with a vent hole; the high-pressure steel pipe is subjected to pipe shrinkage to form a clamping groove for clamping the annular bottom of the pressure pipe sleeve; a plurality of corresponding rolling grooves are formed on the sleeving end of the high-pressure steel pipe and the pressure pipe sleeve; and a silencing shaft is arranged in the high-pressure rubber pipe. According to the utility model, the high-pressure connection oil pipe can be formed by only the conventional pipe shrinkage process and rolling process; the tight connection between the high-pressure steel pipe and the high-pressure rubber pipe is realized through the pressure pipe sleeve; and the high-pressure connection oil pipe has excellent sealing property.
Description
Technical field
The utility model relates to the high-pressure oil pipe technical field.
Background technique
In hydraulic system, high-pressure oil pipe is important constituent elements, is responsible for the conveying of hydraulic oil, and the quality of its sealability directly has influence on the normal operation of hydraulic system.The two ends of high-pressure oil pipe all are equipped with steel pipe joint, with connecting fluid press mechanical pressing equipment.The sealability of existing high pressure connected pipes is poor, and the time has been grown easy generation oil impregnate phenomenon.Therefore, be necessary to research and develop a kind of high pressure connected pipes of good seal performance.
The model utility content
The technical problems to be solved in the utility model is to provide a kind of high pressure connected pipes of good seal performance.
For solving the problems of the technologies described above adopted technological scheme: a kind of high pressure connected pipes, include high-pressure rubber hose, Steel Tube Special, pressure pipe sleeve and attaching nut, it is characterized in that: described attaching nut is installed on the horn mouth connecting end of Steel Tube Special, the other end of Steel Tube Special is socketed in high-pressure rubber hose, the socket end of high-pressure rubber hose is set with the pressure pipe sleeve, the circular bottom part of pressure pipe sleeve is sleeved on Steel Tube Special, the pressure pipe sleeve offers exhaust port near this end of circular bottom part, Steel Tube Special forms to clamp the clip slot of the circular bottom part of pressure pipe sleeve by the draw, the socket end of Steel Tube Special and pressure pipe sleeve forming have the rolling groove of some correspondences, be provided with the noise reduction axle in high-pressure rubber hose.
The beneficial effect that adopts the utility model to bring: processing the utility model only need adopt conventional draw technique and rolling technology just plastic, realize that by the pressure pipe sleeve the tight connection between Steel Tube Special and high-pressure rubber hose connects, and has splendid sealability.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model high pressure connected pipes.
