Abstract

A rapid connecting union for an oil field can solve the problems that a traditional union is tedious and complex in installation process, difficult to overhaul and inconvenient to use temporarily. The rapid connecting union for the oil field comprises a left joint and a right joint. The standard of the left end of the left joint is identical to that of the right end of the right joint. The inner wall of the left end of the left joint and the inner wall of the right end of the right joint are respectively provided with threads. The left end of the right joint is sleeved with the right end of the left joint and the left end of the right joint and the right end of the left joint are in mutual clearance fit. An annular groove is formed in the outer wall of the left end of the right joint. A sealing ring is arranged in the groove. The right end of the left joint and the corresponding portion of the right joint are respectively provided with an annular boss. The annular bosses are sleeved with an annular outer sleeve device. The outer sleeve device comprises an upper lantern ring and a lower lantern ring hinged to the upper lantern ring. The inner side of the upper lantern ring and the inner side of the lower lantern ring are respectively provided with an annular stabilizing groove. Each annular boss is sleeved with one stabilizing groove. Locking devices matched with each other are arranged at the upper end of the upper lantern ring and the lower end of the lower lantern ring respectively. The rapid connecting union for the oil field is safe in operation, convenient to use and maintain, simple in manufacturing technology, rapid in installation and high in practicality.

Description

Oil field connects the oily ninth of the ten Heavenly Stems by speed

Technical field

The utility model belongs to the conveyance conduit technical field, relates to the conveyance conduit interface equipment, and specifically oil field connects the oily ninth of the ten Heavenly Stems by speed.

Background technique

The oily ninth of the ten Heavenly Stems, pipe union namely, be widely used in the hydraulic pipe line and automation equipment of all kinds of machineries such as petroleum machinery, metallurgical machinery and engineering machinery, along with scientific and technological progress, oil is divided into welding type, FERRULETYPE, flared type etc. the ninth of the ten Heavenly Stems now, yet all has the problem that complex installation process is complicated, be difficult for maintenance and be not easy to Interim use these traditional oily ninth of the ten Heavenly Stems.

Summary of the invention

The utility model is for solving traditional complicated, difficult maintenance of oily complex installation process in the ninth of the ten Heavenly Stems and the problem that is not easy to Interim use, and the oil field proposed connects the oily ninth of the ten Heavenly Stems by speed, comprise left joint and right connector, left joint left end and inwall identical with right connector right-hand member specification is equipped with screw thread, described right connector left end is inserted in left joint right-hand member and Spielpassung each other, right connector left end outer wall has annular groove, be provided with seal ring in groove, corresponding part on left joint right-hand member and right connector is equipped with annular boss, and annular boss is enclosed within the ring-shaped jacket device; Described coating device comprises the collar and is hinged on the lower collar of collar lower end, and the upper collar and lower collar inboard have the firm groove of annular, in firm groove, are inserted in annular boss, and upper collar upper end and lower collar lower end are provided with the locking device be fitted to each other.

The annular groove of described left joint left end outer wall is opened in left joint right-hand member inwall, and is provided with seal ring in groove.

The beneficial effects of the utility model: the right connector left end is inserted in to left joint right-hand member, and utilize the seal ring sealing to prevent seepage, hinged relationship by the upper collar and lower collar, annular boss is inserted in the firm groove of coating device, and utilize locking device fastening, make between left joint and right connector, be connected fastening, be difficult to separate, most of surge pressure in course of conveying, two arms by firm groove are born, greatly reduce the possibility of leakage, and be provided with seal ring, between left street corner and right connector, no longer be threaded, make connection more reliable, and handling safety, easy to use, be convenient to maintenance, manufacturing process is simple, install quick and practical, can use for a long time and also be convenient to Interim use.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

The side structure schematic diagram that Fig. 2 is coating device in Fig. 1.

In figure: the left joint of 1-, 2-right connector, 3-annular boss, 4-seal ring, 5-coating device, the upper collar of 6-, 7-lower collar, the firm groove of 8-, 9-locking device.

Embodiment

Below in conjunction with Fig. 1 and Fig. 2, the utility model is described in further detail, oil field connects the oily ninth of the ten Heavenly Stems by speed, comprise left joint 1 and right connector 2, left joint 1 left end and inwall identical with right connector 2 right-hand member specifications is equipped with screw thread, left joint 1 is threaded connection the port at a pipeline, right connector 2 is threaded connection the port at another pipeline, described left joint 1 right-hand member inner circle and right connector 2 left end cylindrical sizes are approximate, be that right connector 2 left ends are inserted in left joint 1 right-hand member and Spielpassung each other, thereby right connector 2 is inserted in to left joint 1 by two pipeline communications, right connector 2 left end outer walls have annular groove, be provided with seal ring 4 in groove, so that by the pipeline closed be communicated with, traditional mode is that two pipelines directly are threaded, and utilize and to strike the mode such as pound and connect tightly, but because there is no seal ring 4, make liquid still easily overflow, corresponding part on left joint 1 right-hand member and right connector 2 is equipped with annular boss 3, annular boss 3 is enclosed within ring-shaped jacket device 5, described coating device 5 comprises the collar 6 and is hinged on the lower collar 7 of the collar 6 lower ends, the upper collar 6 and lower collar 7 inboards have the firm groove 8 of annular, be inserted in annular boss 3 in firm groove 8, and with annular boss 3 Spielpassung, because annular boss 3 is protruding structure, after being inserted in firm groove 8, make left joint 1 can't separate with right connector 2, effective being connected between firm left joint 1 and right connector 2, and the sidewall of firm groove 8 is born the impact force in pipeline, make leak preventing effect better, annexation is more reliable, the upper collar 6 upper ends and lower collar 7 lower ends are provided with the locking device 9 be fitted to each other, by after locking device 9 lockings, the upper collar 6 and lower collar 7 are by the left joint 1 of fastening and right connector 2, guarantee whole firm annexation.

The annular groove of described right connector 2 left end outer walls is opened in left joint 1 right-hand member inwall, and is provided with seal ring 4 in groove, changed the position of annular groove, but its effect reached is identical.

Hinged relationship between the described upper collar 6 and lower collar 7, can utilize rotating shaft and win in succession or connect piece and connect, going up the collar 6 lower ends is fixed with and wins in succession, win in succession and be provided with rotating shaft, be connected with piece in rotating shaft, connect piece and be fixed on lower collar 7 upper ends, advantage is to bear the larger power of pullling, and shortcoming is to take up room greatly.
