Description

Technical Field

[0001] The invention belongs to the technical field of pipeline connectors, and in particular relates to an emergency connector for a grooved steel pipe. Background Art

[0002] In modern warfare, the main way to ensure wartime oil supply is through oil pipeline transportation. Ensuring that the oil pipeline reaches the designated location in a timely and accurate manner to ensure the smooth flow of oil during wartime is a basic task that must be done in military struggle preparation. For large quantities of pipelines that are frequently connected and disassembled to replace the transportation site, frequent connection and disassembly operations are performed between the pipeline and the connector. Socket connectors are divided into double-socket connectors and single-socket connectors. Socket connectors (referred to as connectors) are intermediate connection pipeline connectors used to connect steel infusion pipelines. When the connector is frequently loaded and unloaded, the lip of the key part of the sealing rubber ring is damaged and leaks occur, or because of a long time, the sealing rubber ring is aged or the outer surface of the groove head of the groove head of the steel pipe is bumped and uneven, or there are foreign objects on the sealing surface that have not been cleaned up, and other special scenarios, the sealing pair fails and leaks occur.

[0003] Therefore, inventing an emergency connector to solve the problem of temporary leak plugging when a sudden leak (seepage) occurs has become an urgent problem to be solved. Summary of the invention

[0004] The purpose of the present invention is to overcome the above-mentioned deficiencies of the prior art and to provide an emergency connector for emergency leak plugging of connectors in infusion pipelines, which is quick, convenient and simple in structure.

[0005] The technical scheme of the present invention is as follows: it comprises two connecting rings, a circle of studs are arranged around the periphery of the two connecting rings, and nuts are arranged at the ends of the studs; the connecting ring is formed by splicing two semi-circular arc plates, the bottom splicing part of the two semi-circular arc plates is hinged, the upper splicing part of the two semi-circular arc plates is connected by a bolt assembly, and the inner edge of the semi-circular arc plate is provided with a mounting groove; the root part of the semi-circular arc sealing rubber pad is divided into two parts, one part is the inner edge part which is vulcanized as a whole with the semi-circular arc skeleton groove, and the other part is the outer edge part; the inner edge part of the root part of the semi-circular arc sealing rubber pad is placed in the semi-circular arc skeleton groove, and the outer edge part of the root part of the semi-circular arc sealing rubber pad is installed in the mounting groove arranged on the inner edge of the semi-circular arc plate; the mounting groove and the semi-circular arc skeleton groove constitute a receiving groove at the root part of the semi-circular arc sealing rubber pad, and the head of the semi-circular arc sealing rubber pad extends out of the notch of the receiving groove; when the two semi-circular arc plates are spliced ​​into a connecting ring, the two semi-circular arc sealing rubber pads are spliced ​​into a complete sealing rubber pad ring.

[0006] After the semi-circular arc sealing pad and the semi-circular arc frame groove are vulcanized into one, during installation and use, the tip of the semi-circular arc sealing pad head is squeezed into the connector slot. At this time, the outer ring of the semi-circular arc sealing pad root is in the semi-ring groove, and the inner ring is the metal semi-circular arc frame groove. There is no room to let go, so feel free to squeeze in the middle. The function of the semi-circular arc frame groove is: when replacing the semi-circular arc sealing pad and the semi-circular arc frame groove, they can be quickly pulled out from the installation groove.

[0007] The two connecting rings are a fixed connecting ring and a movable connecting ring. The fixed connecting ring has threaded fixing holes for fixing the studs around it, and the movable connecting ring has through holes for allowing the studs to pass through it around it. The function of the fixed connecting ring is: during the relative installation process, one end of the stud is screwed into it through its threaded hole and then tightened with a nut. The stud and the fixed connecting ring are relatively fixed. During use, the end of the fixed connecting ring is first placed against one end face of the connector to fix the fixed connecting ring first. The function of the movable connecting ring is: the through hole in the movable connecting ring passes through the other end of the stud. During use, the movable connecting ring is first moved to the middle by tightening the outer nut of the movable connecting ring.

[0008] The bolt assembly comprises a movable bolt and a fastening nut. One end of the movable bolt is hinged to the upper joint of a semicircular arc plate of the connecting ring, and the other end of the movable bolt is a threaded portion matched with the fastening nut.

[0009] The bolt assemblies on the two connecting rings have the same installation direction, which facilitates the tightening operation.

[0010] When the socket connector to be connected in an emergency is a double-socket connector, the sealing rubber gaskets on the two connecting rings are arranged opposite to each other; when the socket connector to be connected in an emergency is a single-socket connector, the sealing rubber gaskets on the two connecting rings are arranged in the same direction.

[0011] The bottom of the semicircular arc frame groove is evenly distributed with a plurality of circular holes. The circular holes have the following functions: 1. When the semicircular arc sealing rubber pad is vulcanized as a whole, it is tightly meshed with the semicircular arc frame groove; 2. Since both the semicircular arc frame groove and the mounting groove are metal structures, after the semicircular arc frame groove is provided with circular holes, the contact between the sealing rubber pad ring and the mounting groove is increased, and it has a certain flexibility compared with the connection between metal structures. When the semicircular arc sealing rubber pad is installed with the mounting groove of the semicircular arc plate, it is prevented from falling out of the mounting groove in the two-half state.

[0012] The installation groove is a semi-closed semi-annular groove, which consists of a bottom surface, an outer edge surface, and a limiting surface extending radially inward from the end of the outer edge surface. The bottom surface is parallel to the limiting surface, and the bottom of the semicircular arc skeleton groove is in contact with the bottom surface of the installation groove; the outer edge of the root of the semicircular arc sealing pad is directly in contact with the installation groove.

[0013] It is convenient to use general tools to temporarily solve the problem of liquid leakage in the field under emergency conditions. It is fast, convenient and effective, providing a better method for temporary emergency rescue. It can be used for temporary emergency plugging before the pressure at the leakage point drops when the power is not stopped or the power is stopped due to long-distance transportation. It also saves time for formally stopping the power and replacing steel pipes or connectors later, reducing the leakage during this period of time. BRIEF DESCRIPTION OF THE DRAWINGS
