Mixing and discharging multifunctional pipeline system

Abstract

The invention provides a mixing and discharging multifunctional pipeline system. The mixing and discharging multifunctional pipeline system includes a first mixing and discharging inlet pipeline, a first mixing and discharging outlet pipeline, a second mixing and discharging inlet pipeline and a second mixing and discharging outlet pipeline. A connection pipe between outlets is arranged between the first mixing and discharging outlet pipeline and the second mixing and discharging outlet pipeline, and valves are arranged on the connection pipe between the outlets. According to a preferred scheme, and the valve parts are electrically controlled or hydraulically controlled valves. The valves are butterfly valves. The mixing and discharging multifunctional pipeline system can realize multi-path work, for example, by operating the corresponding valves, a plurality of liquid suction and discharging methods such as left suction and left discharging, left suction and right discharging, right suction and right discharging, right suction and left discharging, one suction and double discharging, double suction and one discharging and by-pass manifold without mixing and discharging devices canbe realized, and the connection and placement in a well site of a sand mixing truck during fracturing operation are convenient. It is further convenient to maintain the functions of other parts whensome parts need maintenance, and the continuity of work can be ensured.

Description

technical field [0001] The invention relates to the field of oil drilling and production equipment, in particular to a mixed-row multifunctional pipeline system. Background technique [0002] In the field of oil and natural gas production, the mixed flow device is the core equipment in fracturing construction. The existing mixed flow device mostly adopts a single-line production system, that is, a mixed flow is equipped with a manifold. A problem with the shuffling unit rendered the entire line unusable. For example, the Chinese patent document CN103343679B, an electro-hydraulic hybrid driving sand mixing vehicle, and CN103912259A, an electric driving sand mixing vehicle, all have the above-mentioned problems. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mixed-drainage multi-functional pipeline system, which can retain some functions when some components fail, so as to achieve higher fault tolerance, ensure...
