Description

Can quick mounting blocking flange spool

Technical field

The utility model relates to a kind of crude oil pipeline emergency repair device, be particularly useful for crude oil pipeline perforate construction operation complete after quick mounting blocking.

Background technique

Flange spool can coordinate erection pipe tapping machine and pipeline low pressure plugging device in the work progresss such as crude oil pipeline emergency repair, play after crude oil pipeline emergency work construction completes simultaneously and install and lock blocking, shutoff perforate, the effect of closing duct is one of requisite important device in crude oil pipeline emergency repair work progress.Crude oil pipeline emergency repair is due to the peculiarity and timeliness of operation of speedily carrying out rescue work, time is often particularly valuable in work progress, flange spool used in usual pipeline emergency work construction process needs the stroke to blocking is installed to measure to guarantee that the lock ring of flange spool is corresponding with the groove of blocking in installation blocking link, if corresponding inaccurate also need repeats, the install operation process of blocking is not only loaded down with trivial details but also time-consuming.

Summary of the invention

The purpose of this utility model be to provide a kind of can quick mounting blocking flange spool, in order to install blocking rapidly and accurately in crude oil pipeline emergency work construction process, for crude oil pipeline repairing race against time.

The purpose of this utility model is achieved through the following technical solutions: flange spool is primarily of blocking, blind plate, tee union and lock ring composition, and blocking main structure is blocking slope angle and O-ring seal; Blind plate is fixed with the convenient lifting of blind plate suspension ring and blind plate is fixed by hexagon nut and bolt and flange spool; Lock ring is primarily of lock ring fillet, the spring spool structure of spring constraint body, spring, assembling screw composition, lock ring drive screw, rolling bearing, the parts such as hexagon socket head cap screw and structure composition, lock ring packing ring and lock ring fixed cover seal and are fixed on flange spool.

The beneficial effects of the utility model are: structure is simple, easy to use.The installation of blocking can be completed fast in crude oil pipeline emergency repair work progress, without the need to measuring the stroke of blocking in installation process, make the groove of the lock ring of flange spool and blocking corresponding fast and accurately on, simple flow, easy-to-operat.

Embodiment

The utility model is further described below in conjunction with drawings and Examples.

This flange spool is primarily of tee union 6 as shown in Figure 1 and Figure 2, blocking 5, blind plate 9, and lock ring 10 forms, and tee union 6 plays the connection function in adpting flange pipe nipple and crude oil pipeline operation hole; The bottom cover of blocking 5 has O-ring seal 3, and O-ring seal 3 can play the seal action to crude oil in pipeline, prevents crude oil in pipeline from oozing out; Blind plate 9 is fixed with flange spool by hexagon nut 1 and bolt 2, and the upper end of blind plate 9 is provided with blind plate suspension ring 8 makes blind plate 9 be convenient to lifting operation; As shown in Figure 3, primarily of the spring spool structure of spring constraint body, spring, assembling screw composition, lock ring drive screw, rolling bearing, the parts such as hexagon socket head cap screw and structure form lock ring 10.

The operation tapping of tee union 6 connecting tube of flange spool, lock ring 10 is fixed on flange spool by lock ring fixed cover 19, and undertaken sealing in case crude oil overflows from the joint of lock ring 10 and flange spool by packing ring 18, the spring 13 of lock ring 10 inside is fixed by spring constraint body 12, thus the telescopic direction of restricted spring 13, when carrying out installation blocking 5, blocking 5 enters flange spool inside downwards, blocking slope angle 4 promotes lock ring 10, the inside Compress Spring 13 in lock ring 10 front end, the aftershrinkage of spring 13 pressurized, lock ring 10 takes in the inside of flange spool, blocking 5 is made to continue to advance downwards, when the lock ring 10 of the groove just in time alignment flange pipe nipple of blocking 5, the deformation of spring 13 pressurized recovers, now lock ring 10 enters the upper groove inside of blocking 5 just, flange spool forms lock state with blocking 5, lock ring fillet 11 on lock ring 10 can protect the seal washer 3 in blocking 5 that the broken ring of machinery can not occur in the propelling stroke of blocking 5.Add sealing filler ring 7 on flange spool top after blocking 5 installs and cover blind plate 9, with hexagon nut 1 and bolt 2, blind plate 9 and flange spool being fixed.Now crude oil pipeline completes the installation of blocking, and pipeline becomes closed condition.

When crude oil pipeline needs take out blocking 5 and again open, first hexagon nut 1 and bolt 2 are backed out, carry out lifting operation by blind plate suspension ring 8 and remove blind plate 9, HEX HEAD CAP SCREWS cutter is adopted to rotate hexagon socket head cap screw 17, now lock ring drive screw 15 rotates under the drag reduction effect of rolling bearing 16, and drive the front end of lock ring 10 to shrink, and the spring spool structure of lock ring 10 front end can become an entirety internally to shrink until remove the constraint for blocking 5 with lock ring 10 row under the effect of assembling screw, now block 5 to be well under the cooperation of getting stifled instrument taking-up, reach the object opening crude oil pipeline.
