Abstract

Provided is a quick pipeline coupling. The quick pipeline coupling comprises a pressing cap (1), a retainer ring (2), a center body (3) and a sealing ring (4). The quick pipeline coupling is characterized in that a core tube (301) is arranged in the center of a quick pipeline coupling body, the sealing ring (4) is arranged on the core tube (301), a hexagonal prism is arranged in the middle of the center body (3), external threads are formed in the two ends of the center body (3), an annular space is arranged between the external threads and the core tube (301), the bottom of the annular space is of an arc shape, the retainer ring (2) is installed in the space, and the pressing cap (1) is connected with the center body (3) through the external threads so as to tightly press the retainer ring (2). The quick pipeline coupling is applicable to quick connection of an emptying rubber blow-off pipe for equipment maintenance in the process of production of a metering station, a water allocating station, a combination station and a water injection station of an oil field, the rated working pressure of the quick pipeline coupling is 1.0 Mpa, the speed of equipment maintenance is increased, loss of oil energy sources and loss of water resources are prevented, environmental pollution is avoided, the labor intensity of workers on duty is reduced, and normal production of the oil field is ensured.

Description

Pipeline rapid pipe joint
Technical field
the utility model relates to soft pipeline connection pipe fitting in field produces, specifically a kind of pipeline rapid pipe joint.
Background technique
in oilfield metering station, distributing room for water injection, multi-purpose station, water-injection station are produced, device maintenance emptying is regular work, often blowdown sebific duct length is inadequate, conventionally bundle and connect inserting with iron wire with steel pipe short circuit, so frequent generation sump oil sewage thorn leaks phenomenon, not only causes energy loss, and befouling environment, the intensity that increases post workman's work, affects oil field and normally produces.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of pipeline rapid pipe joint is provided.
the technical solution of the utility model comprises: pressure cap, collar, centerbody, seal ring.Its pipeline rapid pipe joint center is provided with core pipe, and core pipe is provided with seal ring, and the centre of centerbody is provided with hexagonal prism, two ends are provided with outside thread, between outside thread and core pipe, be provided with in the space that annular bottom portion is arc collar is housed, be connected with centerbody outside thread by pressure cap, by rand pressing.
the collar outer ring of above-mentioned pipeline rapid pipe joint is curved annular structure, is provided with 30~45 ° of openings.
centerbody one end of above-mentioned pipeline rapid pipe joint is also made as female adapter or male connection.
the beneficial effects of the utility model are: be applicable to device maintenance emptying blowdown sebific duct in oilfield metering station, distributing room for water injection, multi-purpose station, water-injection station production and connect fast, rated working pressure 1.0Mpa, improve device maintenance speed, prevent oil, Water Energy loss, avoid befouling environment, alleviate the intensity of post workman's work, ensure that oil field normally produces.
Accompanying drawing explanation
fig. 1-the utility model master is depending on partly cuing open structural representation.
the main TV structure schematic diagram of Fig. 2-the utility model collar 2.
in figure, 1. pressure cap, 2. collar, 3. centerbody, 301. core pipes, 4. seal ring, 5. sebific duct; C. opening.
Embodiment
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
pipeline rapid pipe joint is made up of pressure cap 1, collar 2, centerbody 3, seal ring 4.Its pipeline rapid pipe joint center is provided with core pipe 301, core pipe 301 is provided with seal ring 4, the centre of centerbody 3 is provided with hexagonal prism, be convenient to unload, two ends are provided with outside thread, between outside thread and core pipe 301, be provided with in the space that annular bottom portion is arc the collar 2 that outer ring is curved annular is housed, collar 2 is provided with 45 ° of open C.Be connected with centerbody 3 outside threads by pressure cap 1, collar 2 is compressed.When use, core pipe 301 is inserted to sebific duct 5, pressure cap 1 is tightened.
