Abstract
The utility model discloses a pipe joint, which comprises a contact (2), wherein the surface of the contact (2) is plated with a coating (1). After the structure is adopted, the hardness of the contact surface can be increased, and connecting pieces have closer fit, thereby improving the pressure in an oil passage pipe and ensuring that an oil passage is safer.
Description
Technical field
The utility model relates to a kind of pipe joint, specifically is a kind of stainless steel joint for pipeline that the space flight and aviation oil-way system connects the consistent lubricant pipe that is used for.
Background technique
In the space flight and aviation oil-way system, pipe joint is the main connector element in the pipework, and it comprises contact head.The contact head surface hardness of traditional stainless steel joint for pipeline is low, and link cooperates not tight, so the system pressure of oil circuit is lower.
The model utility content
Technical problem to be solved in the utility model is a kind of contact surface hardness height to be provided, to cooperate pipe joint tight, that can improve oil-way system pressure.
For solving the problems of the technologies described above, a kind of pipe joint that the utility model provides comprises contact head, and described contact head surface is coated with one deck coating.
After adopting above structure, owing to plated one deck coating on the contact head surface of pipe joint, increased contact surface hardness, it is tightr that link is cooperated, and also increased oil circuit pressure.
As improvement, described coating thickness scope is 0.004mm～0.007mm.So more can make the surface property of pipe joint contact head reach the optimum state.
Description of drawings
Diagram is the structural representation of the utility model pipe joint.
Wherein, 1, coating; 2, contact head.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of the utility model pipe joint shown in the figure as can be known, the utility model pipe joint comprises contact head 2, and described contact head 2 surfaces are coated with one deck coating 1, and the thickness range of described coating is 0.004mm～0.007mm.Described coating can adopt titanium nitride.Handle through titanizing on such pipe joint contact head surface, has increased contact surface hardness, and it is tightr that link is cooperated, thereby improved oil circuit pipe internal pressure, and make oil circuit obtain to guarantee safer.
Claims (2)
1, a kind of pipe joint comprises contact head (2), it is characterized in that: described contact head (2) surface is coated with one deck coating (1).
2, pipe joint according to claim 1 is characterized in that: described coating (1) thickness range is 0.004mm～0.007mm.
