Abstract
The invention discloses a centralized type spherical pig receiving device which comprises a pig receiving cylinder body. At least a route of spherical pig receiving pipeline is arranged just above the pig receiving cylinder body, the spherical pig receiving pipeline comprises inlet pipelines, pig receiving switching valves, barrier strip tee joints and flow switching valves are arranged at a position on the inlet pipeline near the pig receiving cylinder body for piping, and the spherical pig receiving pipeline is connected with the pig receiving cylinder body through a spherical pig inclined-in type inlet. The invention completes pig receiving operations of each route of the inlet pipeline through flow switching by arranging a plurality of routes of the inclined-in type spherical pig inlet pipelines and utilizing matched switch motion of the pig receiving switching valves with the flow switching valves on each inlet pipeline, can complete centralized spherical pig receiving operations of the plurality of pipelines, and has the advantages of less necessary supporting valves, convenient installation, simple and convenient operation, simple flow, small occupying area, low investment, safety and reliability.
Description
Technical field
The present invention relates to a kind of oil gas treating apparatus, especially relate to a kind of spherical pig receiving system.
Background technology
Exploitation along with increasing large-scale self-contained oil gas field; Outlying area such as desert particularly, gas production (oil) pipeline is more and more longer, and many wells gas collection (oil) technology constantly develops; Single well pipeline needs pigging to improve transfer efficiency and utilizes the preparatory film of spherical pig to prevent the demands such as corrosion of rotten acid medium to pipeline; The individual well pigging is more and more important, and the multichannel pipeline is provided with the pigging ball collecting device in the station also more and more, so that can satisfy the pipe safety service requirement.
Individual well (or the multichannel pipeline) pigging that adopts at present has two kinds of forms:
The one, each mouthful individual well is all established the spherical pig receiving system, this kind set-up mode, and it is many that single ball collecting device need be set, and supporting valve is many, and inconvenience is installed, and takes up an area of greatly, and investment is many.
Another kind is to reserve portable spherical pig receiving system to each individual well, though this kind mode has been economized the part valve; But owing to all need reinstall the spherical pig receiving system during each pigging, and inconvenient installation, each mouthful individual well needs bigger operating space simultaneously; And owing to reasons such as high operating pressures; Active joint is selected and inconvenient installation, is prone to cause leakage, has hidden danger.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of centralized spherical pig receiving system, the receipts ball exercise that can effectively solve the multichannel pipeline is done, and takes up an area of and lacks, and supporting operating process is simple, has guaranteed the safety of production run.
The technical solution adopted for the present invention to solve the technical problems is: a kind of centralized spherical pig receiving system; Comprise ball collecting barrel; At least one road spherical pig is set directly over ball collecting barrel receives the bulb line; Said spherical pig is received the bulb line and is comprised inlet line, on inlet line, near ball collecting barrel place pipe arrangement receipts ball transfer valve, blend stop threeway and flow process transfer valve is installed, and said spherical pig is received the bulb line and is connected with ball collecting barrel through the oblique formula import of spherical pig.
The angle of oblique formula import of said spherical pig and ball collecting barrel left end is 40 °～70 °; The oblique formula import of said spherical pig is provided with logical ball indicator; Said ball collecting barrel is 3 °～10 ° scope setting by high right low, angle of inclination, a left side.
Compared with prior art, good effect of the present invention is: through the oblique formula spherical pig of multichannel inlet line is installed, and utilize the cooperation switch motion of receipts ball transfer valve and flow process transfer valve on every inlet line to carry out flow process to switch the receipts ball exercise work of accomplishing each road inlet line; Can accomplish the concentrated pigging of multichannel pipeline and receive the ball operation, required supporting valve is few, easy for installation; Easy and simple to handle, flow process is simple, and floor space is little; Reduce investment outlay, safe and reliable.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structural representation of the present invention.
The specific embodiment
A kind of centralized spherical pig receiving system; As shown in Figure 1, comprise that blind flange lid 1, water filling purge mouthfuls 2, gauge port 3, drain 4, build the oblique formula import of equilibrium mouth 5, spherical pig 6, reserved opening 7, inlet line 8, receive ball transfer valve 9, logical ball indicator 10, blend stop threeway 11, flow process transfer valve 12, ball collecting device outlet 13, ball collecting barrel 14, fast opening blind 16, produce header 17.Wherein:
Blind flange lid 1 is connected with ball collecting barrel 14 through bolt; Water filling purges mouth 2, gauge port 3, drain 4, builds the upper left side that equilibrium mouth 5 is arranged on ball collecting barrel 14; Be provided with ball collecting device outlet 13 in the upper right side of ball collecting barrel 14,, also gauge port 3, drain 4 and reserved opening 7 can be set in the upper right side of ball collecting barrel 14 simultaneously for easy to operate, security needs; Blowdown leakage fluid dram 15 is positioned at ball collecting barrel 14 near under the right-hand member; At ball collecting barrel 14 low order ends fast opening blind 16 is set.
The oblique formula import 6 of spherical pig is set directly over ball collecting barrel 14, and the oblique formula import 6 of spherical pig is 40 °～70 ° with the angle of ball collecting barrel 14 left ends; The oblique formula import 6 of spherical pig is provided with logical ball indicator 10, near ball collecting barrel 14 place's pipe arrangements receipts ball transfer valve 9, blend stop threeway 11, flow process transfer valve 12 is installed on the inlet line 8.
The oblique formula import 6 of receipts ball transfer valve 9, blend stop threeway 11, flow process transfer valve 12 and spherical pig of inlet line 8 and upward pipe arrangement installation thereof constitutes one road spherical pig receipts bulb line.Can also set up the spherical pig receipts bulb line that two-way or multichannel laterally arrange as required.Receive ball transfer valve 9 and can bivalve be set to guarantee safety according to operating pressure and dielectric property with flow process transfer valve 12.
For the ease of spherical pig in ball collecting barrel 14 apace to the fast opening blind end motion, ball collecting barrel 14 can be 3 °～10 ° scope setting by high right low, angle of inclination, a left side.
Operation principle of the present invention is: carry out flow process through the switch motion of receiving ball transfer valve 9, flow process transfer valve 12 and switch; When certain road pipeline will be received the ball operation; Should guarantee at first that the receipts ball transfer valve 9 on other pipeline that does not carry out pigging operation is in closed condition; Then open the valve of building on the equilibrium mouth 5 centralized spherical pig receiving system is built pressure, open receipts ball transfer valve 9 on the inlet line 8 that needs pigging operation then, open valve on ball collecting device outlet 13, the closing flow path transfer valve 12 and accomplish and receive the ball operation.In addition, because the oblique formula import 6 of spherical pig is to tilt to install to the fast opening blind end according to certain angle of inclination (gradient), institute helps accelerating to receive the flow process that ball exercise is done so that spherical pig moves to the fast opening blind end apace in this cylindrical shell.
