Abstract
The utility model discloses a high-pressure seamless steel pipe for car, including inner tube and outer tube, the inner tube is the phosphating steel pipe, and the outer tube is galvanized steel pipe, inner tube and outer tube both ends set up annular boss and spacing ring respectively, and the annular boss sets up in spacing ring, and the both ends outside that sets up the sealing washer outer tube between annular boss and the spacing ring is through threaded connection threaded sleeve. The utility model has the advantages of reasonable design ingenious, utilize and form certain scalable surplus between annular boss and the spacing ring to the adaptation difference in temperature is great and the service environment who jolts avoids the seepage.
Description
Technical Field
The utility model relates to a high pressure seamless steel pipe for car.
Background
The seamless steel pipe used on the automobile engine is generally smaller in aperture ratio, meanwhile, the working temperature difference of the automobile in a starting state and a stopping state is larger, the seamless steel pipe is easy to deform and leak under the influence of jolting and larger temperature difference, poor sealing is caused to leak, and the normal work of the automobile is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a high-pressure seamless steel pipe for car can reduce the leakage that environmental factor caused.
To achieve the purpose, the utility model adopts the structure that: high-pressure seamless steel pipe for car, including inner tube and outer tube, the inner tube is the bonderizing steel pipe, and inner tube one end sets up first annular boss, and other end port sets up first spacing ring, outer intraductal galvanized steel pipe, outer tube one end set up second annular boss, and other end port sets up the second spacing ring, the inner tube is worn to overlap in the outer tube, the second spacing ring supports first annular boss, sets up the sealing washer between second spacing ring and the first annular boss, and first spacing ring supports second annular boss, sets up the sealing washer between first spacing ring and the second annular boss, the both ends outside of outer tube is provided with the screw thread, has threaded sleeve through threaded connection.
The beneficial effects are as follows: the utility model has the advantages of reasonable design ingenious, utilize and form certain scalable surplus between annular boss and the spacing ring to the adaptation difference in temperature is great and the service environment who jolts avoids the seepage.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
All of the features disclosed in this specification, or all of the steps of any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.
