Description
Technical Field
The utility model relates to an oil pipe joint, in particular to an oil pipe variable buckle joint.
Background
The existing oil pipe joint is mainly used for connecting two male buckle oil pipes with the same specification, or connecting two female buckle oil pipes with the same specification, or connecting two male buckle oil pipes or female buckle oil pipes with different specifications. While two tubing joints are typically required for connection of pin and box pipes of different gauges, one being a double-ended box reducer joint and the other being a double-ended pin joint. The mode of connecting the male buckle and the female buckle pipes with different specifications has the advantages that on one hand, the connection operation is complex, the cost of two sets of joints is high, and the storage, the transportation and the management are not facilitated; on the other hand, the short circuit of the oil pipe is dismounted by using the pipe tongs, slipping is easy during dismounting, screwing is time-consuming and labor-consuming, and dismounting efficiency is reduced.
Disclosure of Invention
In order to solve the technical problems, the utility model provides an oil pipe variable buckle connector, which is used for connecting two male buckles and female buckles of different specifications; the thick wall reducing part of the joint is provided with an inserting hole capable of inserting an auxiliary screwing rod, the auxiliary screwing of the joint is realized by using the screwing rod, time and labor are saved, and the disassembly and assembly efficiency is improved; and the asbestos buffer cushion is sleeved at the root of the thread of the small-diameter section, so that the damage of the thread tail section can be reduced.
The utility model adopts the technical scheme that: the oil pipe variable buckle joint is a variable diameter joint, the large diameter section of the oil pipe variable buckle joint is provided with internal threads, the small diameter section of the oil pipe variable buckle joint is provided with external threads, an outer boss is arranged between the small diameter section and the end part of the variable diameter, 4 jacks uniformly distributed on the circumference are formed in the outer boss, and an asbestos buffer pad is sleeved on the side surface of the outer boss.
Further, the thickness of the outer boss is not less than 10 mm, and the width thereof is not less than 10 mm.
Further, the inner diameter of the insertion hole on the outer boss is not smaller than 6 mm.
Further, the thickness of the asbestos cushion is not less than 3 mm.
Further, the number of the asbestos cushion is at least 2.
Further, the surface of the oil pipe variable buckle joint is plated with a tungsten layer.
The utility model has the beneficial effects that: the oil pipe variable buckle connector is used for connecting two male buckle oil pipes and female buckle oil pipes with different specifications; the thick wall reducing part of the joint is provided with an inserting hole capable of inserting an auxiliary screwing rod, the auxiliary screwing of the joint is realized by using the screwing rod, time and labor are saved, and the disassembly and assembly efficiency is improved; and the asbestos buffer cushion is sleeved at the root of the thread of the small-diameter section, so that the damage of the thread tail section can be reduced.

Detailed Description
Examples
Referring to fig. 1 and 2, an oil pipe variable buckle connector is a reducing connector, a large diameter section of the oil pipe variable buckle connector is provided with an internal thread 1, a small diameter section of the oil pipe variable buckle connector is provided with an external thread 4, an outer boss 5 is arranged between the small diameter section and the end part of the reducing section, 4 jacks 2 uniformly distributed on the circumference are arranged on the outer boss, and an asbestos buffer pad 3 is sleeved on the side surface of the outer boss; the thickness of the outer boss is not less than 10 mm, the width of the outer boss is not less than 10 mm, and the inner diameter of the jack on the outer boss is not less than 6 mm; the thickness of the asbestos cushion is not less than 3 mm, and the number of the asbestos cushion is at least 2; the surface of the oil pipe variant buckle joint is plated with a tungsten layer.
The connector is used for connecting two male and female buckle oil pipes with different specifications, and is often required to be connected with the male and female buckle oil pipes with different specifications in the oilfield production process and used for connecting pipelines such as a dirty oil water pipe network or a hot washing pipe network. Taking a DN65 (two inch and half) pin pipe and a DN40 (one inch and half) box pipe as an example, the internal thread (box) of the variant buckle joint is connected with the pin of DN65, and the external thread (pin) of the variant buckle joint is connected with the box of DN 40. During the connection process, the variac joint is screwed with the aid of a screw rod, a crowbar or an iron rod, which is inserted into the insertion hole of the thick-walled section of the variac joint. The iron rod screwing joint can be independently used, and can also be matched with a pipe wrench to screw, so that the pipe wrench can be effectively prevented from slipping, and the screwing efficiency and quality are improved. When the female buckle of DN40 is connected, the thread at the tail part is easy to stack under the condition of no gasket because the pipe diameter is smaller (when the thread is processed, the tail part of the thread is not the full-thread, the thread at the tail part is thinner, and when the internal thread and the external thread are mutually screwed and tightly propped, the thread tail section which is disassembled and assembled for several times is easy to deform and stack). The asbestos buffer pad sleeved on the small-diameter section can prevent the DN40 pipe from being screwed with the variable buckle joint to be tightly propped against, so that the damage of the thread tail section is reduced, and the safety and reliability are realized.
