Embodiment Construction
[0032] combine figure 1 , figure 2 , image 3 As shown, a pig receiving and buffering system provided by the present invention includes: anti-collision plate 1, connecting flange 2, piston rod 3, piston head 4, bearing 5, check ring 6, outer cylinder body 7, Inner cylinder block 8, base 9 and fixing bolt. Wherein, the outer cylinder body 7 is provided with an inflation valve 12 . The inner cylinder 8 is provided with an orifice 10 , and when the piston rod 3 receives an external force and pushes inward, the hydraulic oil in the inner cylinder 8 flows out of the inner cylinder 8 through the orifice 10 . The sealed cavity between the outer cylinder body 7 and the inner cylinder body 8 is the accumulator chamber 11, and the accumulator chamber 11 is used to push the piston rod 3 to the top of the inner cylinder body 8 when the piston rod 3 is reset.
[0033] According to a preferred embodiment of the present invention, such as Figure 4 As shown, the large end surface of th...

The invention discloses a receiving and buffering system for a pipe cleaner. The receiving and buffering system comprises an anticollision board, a connecting flange, a piston rod, a piston head, a bearing, an outer cylinder body, an inner cylinder body, a check baffle ring and a base, wherein the anticollision board, the connecting flange, the piston rod and the piston head are sequentially connected; the piston rod is arranged in the centre of the bearing; the bearing is connected with the outer cylinder; the check baffle ring is connected with the piston head; the outer cylinder body and the inner cylinder body are fixed on the base; the outer cylinder body is provided with an inflation valve; orifices are formed in the inner cylinder body; and a sealed cavity between the outer cylinder body and the inner cylinder body is an accumulating cavity. According to the receiving and buffering system for the pipe cleaner, the hydraulic buffering principle is applied to the receiving system for the pipe cleaner, so that the system can completely absorb inertia force of the pipe cleaner and a pigging detector, and is compact in structure, safe and reliable.
Description
technical field [0001] The invention belongs to the field of oil and gas pipeline mechanical equipment, and in particular relates to a pig receiving buffer system. Background technique [0002] With the advancement of technology, the development of oil and gas pipelines tends to be high-pressure and large-diameter, and the specification and quality of the matching pigs are increased. Especially in order not to affect the normal transportation of the pipeline, it is necessary to carry out the detection of the pipeline synchronously with the transmission medium. However, Due to the high pressure and fast speed of the pipeline transport medium, when the large-scale high-speed pigging detector synchronously moving with the medium enters the pig receiving barrel, it is difficult to stop in time due to inertia and impacts on the quick-opening blind plate on the pig receiving barrel , resulting in deformation of the blind locking mechanism and even safety accidents. At present, th...
