Abstract
The invention discloses a petroleum pipeline coupling with a compensation function. The petroleum pipeline coupling comprises coupling bodies and a rubber connecting pipe. The two coupling bodies are arranged and provided with inner threads. The rubber connecting pipe is in a fat belly shape with the two thin ends and the thick middle part. The two ends of the rubber connecting pipe are fixedly connected to the coupling bodies in a sleeving manner. The outer portion of the rubber connecting pipe is provided with a heat preservation shell layer. The coupling can offset stretching and contracting of a petroleum pipeline due to the outside or petroleum temperature change; and couplings are arranged at a certain interval, and the problem of pipeline damage caused by pipeline stretching and contracting can be solved.
Description
Technical field
The present invention relates to petroleum pipeline attachment technique field, especially a kind of have petroleum pipeline box cupling with compensation for.
Background technology
Through connecting frequently with box cupling when petroleum pipeline connects, box cupling body has female thread, corresponding with the external screw thread of petroleum pipeline,
During connection, petroleum pipeline is threaded connection, with connecing solid, the connection that can achieve pipeline, this connected mode is than very fast
Speed, sealing is also relatively good.When petroleum pipeline lays in the environment that day and night temperature is big or the seasonal temperature difference is big, or stone
During oil temperature change street, petroleum pipeline can be a certain degree of flexible because of the change generation of temperature, is at this moment accomplished by every certain
Distance setting has pipe fitting with compensation for, to offset the change of pipeline.
Content of the invention
The invention aims to solving the above problems, there is provided a kind of have petroleum pipeline box cupling with compensation for.
The purpose of the present invention to implement by the following technical programs：
A kind of have petroleum pipeline box cupling with compensation for, and including box cupling body and rubber linking tube, described box cupling body is 2, connects
Hoop body has female thread, and described rubber linking tube is thick fat tripe shape between the detail of two ends, and the two ends of described rubber linking tube are solid respectively
Surely it is socketed on box cupling body, described rubber linking tube peripheral hardware is incubated shell.
Further, described rubber linking tube is the Oil resistant rubber tube of steel reinforcement.
Further, described box cupling body and the length of rubber linking tube junction are the 1/4 of box cupling body length.
Further, described insulation shell is preferably mineral wool cartridge.
Beneficial effects of the present invention are：
One kind that the present invention provides has petroleum pipeline box cupling with compensation for, can offset petroleum pipeline because of extraneous or oil temperature
It is flexible that degree changes and produces, and arranges this box cupling at a certain distance, can prevent the Pipeline damage leading to due to pipeline extension from asking
Topic.
Brief description
Fig. 1 has the structure chart of petroleum pipeline box cupling with compensation for for the present invention.
In figure：1- box cupling body；2- mineral wool cartridge；3- rubber linking tube；4- female thread.
Specific embodiment
As shown in figure 1, having petroleum pipeline box cupling with compensation for described in the embodiment of the present invention, including box cupling body 1 and rubber
Gemel connection pipe 3, described box cupling body 1 is 2, and box cupling body 1 has female thread 4, and described rubber linking tube 3 is thick fat between the detail of two ends
Tripe shape, the two ends of described rubber linking tube 3 respectively fixedly sleeved on box cupling body 1, box cupling body 1 and rubber linking tube 3 junction
Length be box cupling body 1 length 1/4.Described rubber linking tube 3 peripheral hardware heat preservation rock shell 2.Rubber linking tube 3 material is steel
The Oil resistant rubber tube that silk is reinforced.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to aforementioned reality
Apply example the present invention has been described in detail, for a person skilled in the art, it still can be to aforementioned each enforcement
Technical scheme described in example is modified, or carries out equivalent to wherein some technical characteristics.All essences in the present invention
Within god and principle, any modification, equivalent substitution and improvement made etc., should be included within the scope of the present invention.
