Abstract
The invention discloses a petroleum pipe end connector structure comprising a sealing pipe, an outer casing and two pipe end structures. The two pipe end structures are connected through the sealing pipe, two ends of the sealing pipe are inserted into the pipe end structures, a thread is arranged outside each pipe end structure, and the outer casing is connected with the two pipe end structures through the threads, annular projections are arranged in the middle of the sealing pipe, and sealing pads are respectively arranged on two sides of the annular projections. The two pipe end structures are connected through the outer casing and are sealed through the sealing pipe, the sealing pads on the sealing pipe can be isolated from the external environment due to the outer casing, service lives of the sealing pads can be prolonged and ageing and corrosion of the same can be alleviated.
Description
Technical field
The present invention relates to a kind of petroleum pipeline pipe end interface structure, belong to the petroleum pipeline technical field.
Background technique
Sealing problem after the petroleum pipeline butt joint is a very important problem, prior art is often used flange-interface to connect and is sealed, its structure is comparatively complicated, and the pulling force that bolt bears in the process of flange-interface sealing is bigger, the pulling force that bolt bears is delivered on the flange, also easily flange is brought damage, thus to the requirement of flange than higher.Simultaneously, owing to bear big stress effect for a long time, the bolt that flange and adpting flange are used will inevitably produce the fatigue stress phenomenon after using a period of time, so service time, more easy appearance more of a specified duration damaged.
Summary of the invention
In order to solve the excessive technical problem of pipe end constructions seal structure complex, stress of petroleum pipeline, the invention provides a kind of petroleum pipeline pipe end interface structure.
Purpose of the present invention is come specific implementation by the following technical programs:
A kind of petroleum pipeline pipe end interface structure, comprise sealed pipe, outer sleeve and two pipe end constructions, connect by sealed pipe between two described pipe end constructions, two described pipe end constructions inside are inserted at the two ends of described sealed pipe, the outside of each pipe end constructions is provided with screw thread, described outer sleeve is connected with two pipe end constructions by screw thread, and the neutral position of described sealed pipe is provided with ring-shaped protrusion, and two sides of ring-shaped protrusion are respectively equipped with sealing gasket.
The surface of described sealed pipe is provided with the fin of arranging vertically, and is provided with guide groove in the inside of pipe end constructions, and described fin cooperates with described guide groove.
The middle part of described outer sleeve is provided with integrated hexagon nut structure.
A kind of petroleum pipeline pipe end interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and between two pipe end constructions, be connected and sealed by sealed pipe, because the existence of outer sleeve, sealing gasket on the sealed pipe can be realized with external environment condition isolated, so can prolong the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is a kind of structural drawing of petroleum pipeline pipe end interface structure.
Among the figure: 1, sealed pipe; 2, outer sleeve; 3, pipe end constructions; 4, hexagon nut structure.
Embodiment
As shown in Figure 1, the described a kind of petroleum pipeline pipe end interface structure of the embodiment of the invention, comprise sealed pipe 1, outer sleeve 2 and two pipe end constructions 3, connect by sealed pipe 1 between two described pipe end constructions 3, two described pipe end constructions 3 inside are inserted at the two ends of described sealed pipe 1, the outside of each pipe end constructions 3 is provided with screw thread, described outer sleeve 2 is connected with two pipe end constructions 3 by screw thread, the neutral position of described sealed pipe 1 is provided with ring-shaped protrusion, and two sides of ring-shaped protrusion are respectively equipped with sealing gasket.
The surface of described sealed pipe 1 is provided with the fin of arranging vertically, and is provided with guide groove in the inside of pipe end constructions 3, and described fin cooperates with described guide groove.
The middle part of described outer sleeve 2 is provided with integrated hexagon nut structure 4.
A kind of petroleum pipeline pipe end interface structure of the present invention, by outer sleeve two pipe end constructions are connected, and between two pipe end constructions, be connected and sealed by sealed pipe, because the existence of outer sleeve, sealing gasket on the sealed pipe can be realized with external environment condition isolated, so can prolong the working life of sealing gasket, delay the deterioration phenomenon of sealing gasket, and reduce the problem of the corrosion of sealing gasket.
