Abstract
The utility model discloses a kind of oil pipe collar, including straight tube body, the straight inboard wall of tube body is provided with pawl, and is provided with groove vertically；The internal diameter of the straight tube body is tapered by two lateral centers；The ring body of activity is arranged with the outer wall of the straight tube body, the internal diameter size straight tube body centre outside dimension of the ring body is identical.The utility model coordinates the ring body of periphery using the pipe collar of gradual change internal diameter, convenient to connect or disconnect two sections of petroleum pipelines；Simple structure, it is easy to operate.
Description
Technical field
The utility model is related to technical field of pipeline connection, especially a kind of oil pipe collar.
Background technology
It is a kind of most economical, rational means of transportation by pipeline in petroleum transportation.And pipeline oil, oil
Connected mode between pipe is typically with tubing coupling and is attached, during tubing coupling is oil development, petroleum oil connection
Mechanical part, be mainly used in the connection of oil pipe.Connected pipes are played in tubing coupling, bear tension, lift oil pipe, seal oil pipe
Screw thread etc. is acted on.
Connection sealing between tubing coupling of the prior art and oil pipe is usually first to wind glass in the external screw thread of oil pipe
The oil pipe for being tied with glass fiber or the rope made of hemp, is screwed into tubing coupling by glass silk or the rope made of hemp afterwards, and what above-mentioned seal form was present asks
Topic is：One is that oil pipe and tubing coupling are installed relatively cumbersome, it is necessary to get out glass fiber or the rope made of hemp in advance, in addition the rope made of hemp or glass
The elastic or thickness of silk winding can also influence sealing effectiveness, be difficult to control；Two is practice have shown that being wound using glass fiber or the rope made of hemp
Form carry out oil pipe and tubing coupling sealing, sealing effectiveness is bad, easily crude oil Seepage occurs during use.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of oil pipe collar, and simple structure is easy to use.
In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme：A kind of oil pipe collar, including
Straight tube body, the straight inboard wall of tube body is provided with pawl, and is provided with groove vertically；The internal diameter of the straight tube body is by two lateral centers
Tapered；The ring body of activity, the internal diameter size straight tube body centre outside dimension of the ring body are arranged with the outer wall of the straight tube body
It is identical.
Further, the ring body is torus or square ring body.
Further, the straight tube wall is provided with the depression for accommodating ring body.
Compared with prior art, the utility model has advantages below：Using the pipe collar of gradual change internal diameter, coordinate the ring of periphery
Body, two sections of petroleum pipelines of convenient connection or disconnection；Simple structure, it is easy to operate.
Brief description of the drawings
Fig. 1 is the vertical section structure schematic diagram of the utility model oil pipe collar.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to protection domain of the present utility model.
As shown in figure 1, a kind of oil pipe collar, including penetrating straight tube body 1, petroleum pipeline can be inserted along the two ends of straight tube body 1,
And realize two purposes of petroleum pipeline of connection.
Pawl 12 is provided with the inwall of straight tube body 1, the petroleum pipeline for facilitating insertion into is not drawn out easily, especially in petroleum pipeline
In the case of there is pressure during transfer oil, there is inverted tooth-like effect between straight tube body and petroleum pipeline, petroleum pipeline is not easily disconnected from
Straight tube body.
The two ends of straight tube body 1 are provided with groove 11 vertically, i.e., the both sides tube wall of groove 11 can occur opposing compression be close to, then
The outside of straight tube body 1 is arranged the activity ring body 2 of small internal diameter, and the internal diameter size straight tube body centre outside dimension of ring body 2 is identical, just
Petroleum pipeline is tightly embraced in the movable end of straight tube body 1.
Depression is set on straight tube wall, and ring body 2 can be fastened in depression 13 when mobile, prevent its random movement.
Ring body 2 is annular shape in Fig. 1, and side's ring structure can be set, and can play a part of to clamp straight tube body, while can also add
The intensity of tetanic body.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
