Abstract
Disclosed is a plugging cap for sealing a port of the metal pipe, which belongs to the manufacturing technical field of metal pipe matching components. The utility model is mainly composed of a cone body (2) with an inner hole (1). An inverted tooth profile groove (3) is arranged on the circumference of the small end of the cone body (2); and the ending head of the small end of the cone body (2) is a circular-arc. The utility model is designed elaborately for the reasons that the plugging cap of the present structure comes off easily and the keeping-clean inert gas in an intracavity of the pipe releases out, and for meeting the functions that the plugging cap can not only be pressed into the pipe successfully but also the plugging cap can be prevented from coming off with a good sealing effect. The utility model is easy for the plugging cap to be pressed into the pipe, in particular to preventing the keeping-clean inert gas from releasing out and preventing the plugging cap from coming off with a remarkable sealing effect of the pipe port. The pipe port being sealed with the utility model after the pipe is filled with keeping-clean inert gas can guarantee that the inner surface of the pipe keeps the original cleanliness without oxidization and with fixed color. The utility model is applicable in the copper pipe processing in medical, air-conditioning, refrigeration industry with high cleanliness and good quality in the inner surface, and in other metal pipe processing as well.
Description
Technical field
The utility model relates to a kind of metal tube port sealing blocking cap, belongs to the manufacturing technology field of metal tube matching component.
Background technology
For guaranteeing have the metal tube of cleanliness level requirement in transportation, storage process, not to be subjected to pollution, the oxidation stain of environment to inside face, keep original cleanliness level, need add the sealing of stifled (plug) cap at the metal tube two ends.
At present; the shape of stifled (plug) cap of pipe end sealing roughly has two kinds of cylindrical shape and cone-shapeds, transport, in the storage process, because of being subjected to reasons such as vibration, friction; the coming off of regular meeting causes stifled (plug) cap, loosening and metal tube inner chamber inertia the leaking of gas of keeping a public place clean can not be satisfied operating needs.
Summary of the invention
The purpose of this utility model provides a kind of structure design novelty, reasonable, reliable, can seal with the matching used metal tube port of metal tube inner chamber inflatable protective device and use blocking cap.
The utility model is used blocking cap for the sealing of metal tube port, comprises the conical body of being with endoporus, and it is waited to levy the small end circumference that is conical body and is provided with pawl shape groove.
The small end end of described conical body can be circular arc.
The utility model comes off and the keep a public place clean reason of gas leak of tubing inner chamber inertia easily at stifled (plug) cap of comprehensive analyses existing structure shape, but from satisfy can be successfully with slip-off preventing, sealing function and well-designed again in the blocking cap ascending pipe, be easy to especially to prevent in the blocking cap ascending pipe significant sealing affection of leakage-preventing, slip-off preventing, pipe end.Tubing fills the inertia gas rear port of keeping a public place clean and seals with the utility model, can guarantee that internal surface of pipe keeps original cleanliness level, not oxidation, antifade.Be applicable to the processing of high cleanliness, high inner surface quality copper pipe and other metal pipe materials of medical treatment, air-conditioning, refrigeration industry.
Description of drawings
Accompanying drawing is an integral structure cutaway view of the present utility model.
The specific embodiment
The utility model mainly constitutes with the conical body 2 of endoporus 1, and the small end circumference of conical body 2 is provided with pawl shape groove 3, and the small end end of conical body 2 is a circular arc.The big end external diameter＞small end external diameter＜copper pipe internal diameter of conical body 2, the internal diameter size of endoporus 1 is a bit larger tham the diameter of pressure head bar in the metal tube inner chamber inflatable protective device.
During use, earlier with metal tube inner chamber inflatable protective device with tubing inner chamber air exhaustion and fill the inertia gas of keeping a public place clean, the pressure head of inflating mechanical device with the tubing inner chamber is pressed into pipe end with blocking cap and gets final product again.
Claims (2)
1, blocking cap is used in a kind of metal tube port sealing, comprises the conical body (2) of band endoporus (1), and it is waited to levy the small end circumference that is conical body (2) and is provided with pawl shape groove (3).
2, use blocking cap by the described metal tube port sealing of claim 1, the small end end that it is characterized in that described conical body (2) is a circular arc.
