Embodiment Construction
[0042] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.
[0043] The traditional ball collection device used for pigging of fluid pipelines includes: lock ring type quick opening blind plate, cylinder body, discharge material connection pipe, safety valve connection pipe, vent valve connection pipe, reducer pipe, main line connection pipe, rear saddle type support Seat, sewage valve connection, front saddle support, ball indicator, sewage outlet, medium inlet and other components. There are emergencies such as easy ball jamming, blocked pipes, and easy damage to equipment.
[0044] Based on the above basic components, and aiming at the various problems mentioned above, an embodiment of the present invention provides a new type of automatic ball collection device with higher safe...

The invention discloses an automatic ball collecting device. The ball collecting device comprises a large ball cylinder, a small ball cylinder, a rubber buffer device, an eccentric different-diameterreducer pipe and an automatic control system, wherein the large ball cylinder is arranged at the tail end of the automatic ball collecting device and used for receiving spherical pigs; the diameter ofthe small ball cylinder is smaller than that of the large ball cylinder, and the small ball cylinder is connected with the large ball cylinder through the eccentric different-diameter reducer pipe; the rubber buffer device is arranged at the tail end of the large ball cylinder to prevent mechanical damage caused by too high ball entering speed; the eccentric different-diameter reducer pipe is a same pipe cylinder and is provided with a large head end and a small head end, the large head end is connected with the large ball cylinder, and the small head end is connected with the small ball cylinder; and the automatic control system comprises a sensor, an automatic control valve and an automatic control system. According to the automatic ball collecting device provided by the invention, thesmall ball cylinder is lengthened, so that the problems that large-volume hydrates appear in the pigging process, and spherical pigs cannot enter the large ball cylinder are solved; the large ball cylinder and the small ball cylinder are connected through the eccentric different-diameter reducer pipe to solve the problem of ball clamping; and the buffer device solves the problem of mechanical damage caused by too high speed of spherical pigs entering the ball cylinders.
Description
technical field [0001] The invention relates to the field of pigging of fluid working medium delivery pipelines, in particular to an automatic ball collecting device suitable for pigging of fluid pipelines. Background technique [0002] In-service long-distance natural gas pipelines and compressed air energy storage manifold systems need to be pigged to remove accumulated water, sediment, rust residue, iron sulfide powder, welding slag, impurities, etc. remaining in the pipeline . Pigging can prevent the formation of hydrate in the pipeline, reduce the corrosion of the inner wall of the pipeline by hydrogen sulfide and other acidic substances, and achieve the purpose of improving operation efficiency and prolonging the service life of the pipeline. The traditional ball collecting device is complicated to operate and requires trained professionals to operate. When the pigging ball is stuck, the pressure gauge fails, and the connecting pipe is blocked, accidents are prone to...
