Abstract
The utility model relates to a device for cleaning pipelines, which is a corollary device of an oil collecting pipeline of an oil well. The pressure relief valve mainly comprises a double T-shaped cylinder body and a piston arranged in the cylinder body, wherein the cylinder body is provided with a pressure relief hole, a spring is arranged below a cylinder cover, and the cylinder cover and a piston rod rotate through a special spanner. The pipeline ball dispenser has the advantages of small volume, simple and convenient installation, low cost, easy operation, difficult damage, oil theft prevention function and production safety guarantee. It is especially suitable for cleaning oil pipeline in oil field.
Description
The utility model relates to a kind of device of pipe blow-through, is a kind of corollary equipment of oil well gathering line.
On the oil field in order to remove the bur on the petroleum pipeline inwall, a kind of diameter commonly used is slightly less than the ball of petroleum pipeline internal diameter, and it is put in the pipeline, by pipeline, the attachment in the pipeline is removed under the effect of pressure.Used service robot must install the turnover valve additional before and after it when mounted at present, also needs bypass line UNICOM, also wants mounted valve on the bypass line, and more complicated is installed, and mounting cost is also higher.The cylindrical shell of this service robot itself is up to 1 meter, and it is very difficult that its dress ball position height of installation back reaches 1 meter 6, one workmans operation, often needs 2 people's co-operate, and the expense that wastes time and energy is artificial.And this service robot is equipped with the valve release on cylindrical shell, can emit crude oil by this valve when ordinary production, makes some lawless persons often utilize this valve to steal oil, for safety in production causes a hidden trouble.
The purpose of this utility model is a kind of pipeline service robot simple in structure, easy for installation of design, uses this service robot, and is easy to operate, can accomplish safety in production.
Technical solution of the present utility model is achieved in that a kind of pipeline service robot, is made of cylindrical shell and the cover that is fixedly mounted on the cylindrical shell, its special character is, (1) cylindrical shell is two "T"-shaped hollow cylinders, has pressure relief vent on cylindrical shell, has sealing surface in cylindrical shell.(2) in horizontal hollow cylinder piston is housed, the piston left end has sealing surface, and piston connects with piston rod mutually by screw thread, and positioning seat, seal receptacle and cover plate are installed in the cylindrical shell right-hand member, and encapsulant is housed in the seal receptacle.(3) vertically on the hollow cylinder cover being installed, under the cover spring is housed, between cover and the cylindrical shell encapsulant is housed.
In above-mentioned technical solution, its special character is that (1) piston rod right-hand member is that the cross section is leg-of-mutton termination, has triangular hill in (2) depression on cover.
In above-mentioned technical solution, its special character is, at the piston left end sealing ring is installed.
The utility model has the advantages that (1) this pipeline service robot volume is little, simple in structure, the simple installation expense is low.(2) owing on cylindrical shell, have a pressure relief vent, but during the dress ball in opening the process of cover automatically unloading, easy and simple to handle applicable to service cleaning tube wall in high pressure line, laborsaving saving time.(3) termination of piston rod and top cylinder cover that all to have cross section be leg-of-mutton termination, need just can open with specific purpose tool, have anti-theft feature, can accomplish safety in production.(4) mechanical seal is adopted at the sealing position, and not fragile, maintenance cost is low.
Accompanying drawing 1 is a partial cutaway front view of the present utility model.
Accompanying drawing 2 is partial cutaway vertical views of the present utility model.
Be described further (embodiment) below in conjunction with accompanying drawing:
Manufacture two "T"-shaped cylindrical shells 5 as shown, have the adpting flange of band screw hole at the passage two ends on cylindrical shell 5 left sides, on cylindrical shell 5, have pressure relief vent 2, in cylindrical shell 5, have sealing surface 7.Have sealing surface 8 (chamfering) at piston 9 left ends, the sealing surface 7 in sealing surface 8 and the cylindrical shell 5 matches, and according to circumstances, for the enhanced leaktightness effect, also can in the cannelure of piston 9 left ends sealing ring be installed.Piston 9 axially on have two locating holes, have two backstays on the positioning seat 10, backstay is inserted in the locating hole on the piston 9, piston 9 is bound up by left hand thread and piston rod 6, pack in the cylindrical shell 5, piston rod 6 right-hand members can be installed handwheel, also can make six sides or cubic, in order to prevent the random turn of inoperative personnel, its right-hand member can be done triangularity.Between piston rod 6 and cylindrical shell 5, seal receptacle 11 is installed and is installed additional airtight and watertight padding 13, cover plate 12 is installed in the right-hand member of cylindrical shell 5 by screw thread by screw thread.Sealing ring 3 is contained in cylindrical shell 5 upper port, and spring 4 is installed in the below of cover 1, cover 1 is installed in the upper end of cylindrical shell 5 by screw thread.In order to prevent that the random turn of inoperative personnel from opening cover, can make to have a depression on the cover 1, it is leg-of-mutton projection that the center in the depression has the cross section, with the interior triangle spanner of special use it is screwed.
By the adpting flange on the cylindrical shell 5 this pipeline service robot is connected on the petroleum pipeline,, shifts piston 9 onto high order end, pipeline is sealed up by screw thread with triangle spanner rotary-piston bar 6 in special-purpose.With triangle spanner in special-purpose cover 1 is unloaded, in the process that unloads, the highly pressurised liquid in the cylindrical shell 5 can flow out automatically by pressure relief vent 2 again.Ball (not drawing among the figure) is put in the cylindrical shell 5, again cover 1 is installed on the cylindrical shell 5, spring 4 can push ball, and rotary-piston bar 6 pulls to the right with piston, spring 4 pushes ball, the rotating piston bar 6 again, by piston 9 ball advanced in the pipeline, and piston 9 is also lived seal for pipe joints, under the effect of fluid pressure, promote ball, promptly available ball cleaning pipeline.
