Automatic liquid supply manifold for fracturing construction

Abstract

The invention provides an automatic liquid supply manifold for fracturing construction. The technical problems that a valve of a liquid supply manifold in the prior art needs to be opened and closed manually, and the requirement for operators is high are solved. The automatic liquid supply manifold comprises at least two groups of liquid supply manifold bodies, the at least two groups of liquid supply manifold bodies are connected end to end, a water outlet branch main pipeline (4) is internally provided with a pressure transmitter, the pressure transmitter is electrically connected with a controller, the controller is electrically connected with a power supply and a remote computer, and the controller is further electrically connected with a main pipeline control butterfly valve (6), a branch main pipeline control butterfly valve (7) and a water inlet and outlet branch control butterfly valve (5). Electric and remote control is carried out on the butterfly valves through the controller, liquid level measurement is achieved through the pressure transmitter, automatic control over fracturing liquid supply is achieved, manpower is saved, and efficiency and reliability are improved.

Description

technical field [0001] The invention relates to a liquid supply manifold, in particular to an automatic liquid supply manifold for fracturing construction. Background technique [0002] During fracturing low-pressure liquid supply operations, liquid supply manifolds are often used, such as the low-pressure liquid supply manifold system for fracturing construction with application number CN201620851747.2 and its low-pressure liquid supply manifolds, including the main manifold. diameter manifold, and the flow section of the main manifold decreases from one end to the other end; the end of the main manifold with a larger flow section is connected with a liquid inlet manifold, and at least one inlet manifold is opened on the liquid inlet manifold A liquid port; a plurality of liquid outlets are opened on the outer wall of the main manifold along the axial direction of the main manifold. [0003] The opening and closing of the liquid supply manifold is realized by the action of...
