Abstract
The utility model provides a spherical pig sending and receiving device which is used for natural gas transmission pipelines. The utility model which is mainly composed of a vertical cylindrical body [1], an intake joint [2], an air outlet joint [3], a discharging joint [4] and a sphere filling basket [5] is characterized in that the sphere filling basket [5] can be dismounted, and when the sphere filling basket is installed, the spherical pig sending and receiving device of the utility model is used as a sphere receiving device; after the sphere filling basket is dismounted, the spherical pig sending and receiving device of the utility model is used as a sphere sending device; the air outlet joint on the lower part of the body [1] is made into cone-type, which is suitable for spherical pigs with various diameters to pass.
Description
The present invention relates to a kind of spherical pig R-T unit, be used for the pigging operation of natural gas pipeline.
Natural gas pipeline need regularly carry out pigging operation, removes ducted hydrops and impurity, prevents to result in blockage, and influences the conveying of natural gas.During pigging, drop into spherical pig from ball serving device.Under the promotion of gas pressure, spherical pig moves along gas pipeline, plays pigging, enters ball collecting device then.Existing ball serving device and ball collecting device complex structure, control valve are many, and ball serving device is structurally fully different with ball collecting device, and horizontal ball serving device can't send the spherical pig of diameter less than 150mm.What " natural gas pipeline engineering design " (publishing house of University of Petroleum) announced is exactly this horizontal ball serving device and ball collecting device.
The purpose of this invention is to provide a kind of simple in structurely, both can be used as ball serving device, can be used as ball collecting device again, and can send the spherical pig R-T unit of minor diameter spherical pig.
Task of the present invention is achieved in that in vertical type spherical pig R-T unit a dismountable Sheng cage is arranged.
The spherical pig R-T unit has vertical and cylindrical body always, and there is the taper air outlet adapter its underpart.There are inlet suction port and emptying joint in the body side, and the position of emptying joint is lower than the position of inlet suction port.Dismountable Sheng cage is arranged in the body.Install when containing cage, spherical pig R-T unit of the present invention uses as ball collecting device.Spherical pig from gas pipeline enters the spherical pig R-T unit through inlet suction port, is received in to contain in the cage.After cage was contained in dismounting, spherical pig R-T unit of the present invention used as ball serving device.Drop into spherical pig in the spherical pig R-T unit after, natural gas flows into from inlet suction port, and the promotion spherical pig enters gas pipeline from the taper air outlet adapter of bottom, carries out pigging operation.
Spherical pig R-T unit of the present invention is simple in structure, easy and simple to handle, is easily mounted in the flow process.Both can be used as ball serving device and used, and can be used as ball collecting device again and use.
Describe the details and the working condition of the concrete device that proposes according to the present invention in detail below in conjunction with accompanying drawing.
Fig. 1 is a spherical pig R-T unit schematic diagram of the present invention.
Fig. 2 is the pigging operation flow chart.
Referring to Fig. 1, spherical pig R-T unit of the present invention comprises a vertical type cylinder body [1], and its underpart is taper air outlet adapter [3], and this structure is passed through the spherical pig of different-diameter easily.There are inlet suction port [2] and emptying joint [4] in the body side, and the position of emptying joint is lower than the position of inlet suction port.Dismountable Sheng cage [5] and spherical pig [6] are arranged in the body.Cover plate [7] is arranged above the body, take cover plate apart after, can drop into or take out spherical pig.
Among Fig. 2, A is the spherical pig R-T unit of the present invention after cage is contained in dismounting, uses as ball serving device on stream; B is equipped with the spherical pig R-T unit of the present invention of containing cage, uses as ball collecting device on stream.
During normal gas transmission, valve V1, V2 are in open mode, and valve V3, V4, V5 and V6 are in closed condition.Natural gas is carried by gas pipeline.During pigging, open the cover plate of A, drop into spherical pig.Open valve V3, V4, V5, V6, shut off valve V1 and V2, natural gas flows into spherical pig R-T unit A of the present invention from inlet suction port, promotes the taper air outlet adapter of spherical pig by its underpart, enters gas pipeline, removes ducted hydrops and impurity.Then, spherical pig enters spherical pig R-T unit B of the present invention.Open valve V1, V2, shut off valve V3, V4, V5 and V6 recover normal gas transmission.After opening valve V7, V8 emptying, just the cover plate of removable B takes out spherical pig.
In case of necessity, the Sheng cage among the detachable spherical pig R-T unit B of the present invention at interior input spherical pig, as ball serving device, carries out pigging operation to B to next segment pipe.
Claims (2)
1. a spherical pig R-T unit mainly is made up of body [1], inlet suction port [2], air outlet adapter [3] and emptying joint [4], it is characterized in that, dismountable Sheng cage is arranged in the vertical type cylinder body [1].
