Description
Technical Field
The utility model relates to the field of oilfield equipment, in particular to a tubing coupling device.
Background
A large number of oilfield pipelines can be paved underground in an oilfield, and the oilfield pipelines are limited in length and deep, so that the oilfield pipelines need to be connected in a sealing mode through tubing couplings, and the oilfield pipelines can be paved for use. The tubing coupling is one kind of oil well drilling tool, is mainly used for connecting tubing and mainly solves the problem that the existing coupling is easy to be exhausted and broken due to stress concentration. The existing tubing coupling is designed to be simpler, is only a section of common screwed pipe, cannot ensure the sealing performance of the connection part of the oilfield pipelines after being connected with the oilfield pipelines, and is easy to cause leakage accidents.
SUMMERY OF THE UTILITY MODEL
The utility model mainly solves the technical problem of providing the tubing coupling device which is used for connecting pipelines under an oil field well, can ensure the sealing performance of the connecting part of the pipelines of the oil field and effectively prevent leakage accidents.
In order to achieve the above purpose, the present invention provides the following technical solutions:
this oil pipe coupling ware includes that inside taps the pipe-shaped connecting pipe that has concave screw, and connecting pipe inner wall center department is equipped with the pipe-shaped seal ring of circle perpendicularly, and seal ring passes through a plurality of screws and connecting pipe fixed connection, and connecting pipe both ends sealing connection has the pipe-shaped sealed tube of circle, and the sealed tube all is furnished with annular locking hoop, all installs the hasp on the locking hoop.
As a further optimization of the technical scheme, the connecting pipes are all made of stainless steel.
As a further optimization of the present solution, the sealing washer is made of a rubber material.
As a further optimization of the technical scheme, the sealing pipes are all made of rubber materials and are all connected with the connecting pipe through the bonding agent.
As a further optimization of the technical scheme, the locking hoop and the lock catch are both made of stainless steel.
The beneficial effect of adopting above technical scheme is: when the tubing coupling device is used, two sections of tubing can be screwed into the connecting tube from two ends, and the effect of connecting the tubing is achieved. The end parts of the two oil pipes tightly support against the two sides of the sealing washer, the sealing pipe wraps the two oil pipes respectively, the sealing pipe is tightly tied by the locking hoop, the lock catch is locked, and the sealing pipe is fixed. By utilizing the double sealing function of the sealing pipe and the sealing washer, the sealing performance of the joint of the oil field pipelines can be guaranteed, and the leakage accident can be effectively prevented. The tubing coupling is used for connecting pipelines in the oil field, can ensure the sealing performance of the oil field pipeline connection part, and effectively prevents leakage accidents.
Drawings
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
FIG. 1 is a schematic view of the construction of a tubing collar of the present invention;
figure 2 is a cross-sectional view of the construction of the tubing collar of the present invention.
Wherein, the connecting pipe is 1, the sealing pipe is 2, the sealing washer is 3, the locking hoop is 4, the lock catch is 5, the screw is 6, and the concave thread is 7.
Detailed Description
The preferred embodiments of the tubing coupling of the present invention will be described in detail below with reference to the accompanying drawings.
Figures 1 and 2 show an embodiment of the tubing collar of the present invention:
combine fig. 1 and fig. 2, this tubing coupling ware includes that inside taps the tubular connecting pipe 1 of concave screw thread 7, and 1 inner wall center department of connecting pipe is equipped with tubular seal ring 3 of circle perpendicularly, and seal ring 3 is through a plurality of screws 6 and connecting pipe 1 fixed connection, and 1 both ends sealing connection of connecting pipe has the tubular sealed tube 2 of circle, and sealed tube 2 all is furnished with annular locking hoop 4 of circle, all installs hasp 5 on the locking hoop 4.
The connecting pipe 1 is made of stainless steel, and is firm, durable and good in corrosion resistance. The sealing washer 3 is made of rubber materials, and is soft in material, good in elasticity and good in sealing performance. The sealing tube 2 is made of rubber materials, is soft in material, good in elasticity and good in sealing performance, and the sealing tube 2 is connected with the connecting tube 1 through a binder. The locking hoop 4 and the lock catch 5 are both made of stainless steel, and are firm, durable and good in corrosion resistance.
When the tubing coupling device is used, two sections of tubing can be screwed into the connecting tube 1 from two ends, and the effect of connecting the tubing is achieved. The end parts of the two oil pipes tightly support against the two sides of the sealing washer 3, the sealing pipe 2 wraps the two oil pipes respectively, the sealing pipe is tightly tied by the locking hoop 4, the lock catch 5 is locked, and the sealing pipe 2 is fixed well. By utilizing the double sealing function of the sealing pipe 2 and the sealing washer 3, the sealing performance of the oil field pipeline joint can be ensured, and the leakage accident can be effectively prevented. The tubing coupling is used for connecting pipelines in the oil field, can ensure the sealing performance of the oil field pipeline connection part, and effectively prevents leakage accidents.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the inventive concept of the present invention, which falls into the protection scope of the present invention.
