Description

Technical Field

[0001] The present invention relates to the technical field related to high and low pressure manifolds, and in particular to a large-diameter high and low pressure manifold. Background Art

[0002] The high- and low-pressure manifold is a fracturing process equipment for unconventional oil and gas well exploitation. Its upstream is connected to a sand mixing truck and a liquid tank. The fracturing medium is transported into the low-pressure pipeline of the high- and low-pressure manifold through a low-pressure pump. The fracturing pump truck sucks in the medium through the side outlet of the low-pressure pipeline and boosts its pressure to an ultra-high pressure state, and then transmits it to the high-pressure pipeline of the high- and low-pressure manifold. The medium passes through a swing-type high-pressure check valve and then through the delivery pipeline to transmit the force to the wellhead.

[0003] When using the existing high and low pressure manifolds, due to their small diameter, the fluid flow rate is too fast, which accelerates the erosion and wear of the inner wall of the pipe by the fluid, affecting its service life. In addition, the use of union thread connections has many connection nodes, which makes the threaded connections prone to fatigue damage and fracture due to the impact of high-pressure fluid during operation, reducing the safety of use.
