Jet flow water guiding device

Abstract

The invention discloses a jet flow water guiding device and belongs to the technical field of mine drainage systems. The jet flow water guiding device comprises a gas inlet pipe and a mixing section pipe located at one side of the gas inlet pipe, wherein the right end of the gas inlet pipe is inwards shrunk to form a horn mouth; the horn mouth of the right end of the gas inlet pipe is inserted into the mixing section pipe; the left end of the mixing section pipe and the outer wall of the gas inlet pipe are sealed by blocking; a water inlet pipe which is communicated with the inside of the mixing section pipe is fixed to the outer wall of the mixing section pipe; the right end of the mixing section pipe is inwards shrunk to form a horn mouth; the right end of the mixing section pipe is connected with an outlet section pipe; and the right end of the outlet section pipe is externally expanded to form a horn mouth. Air inside a draining pump is exhausted by the jet flow water guiding device, so that the draining pump is automatically filled with water, the problems that a valve plate is not closed tightly, water leaks and the water feeding difficulty of a water absorption pipe is large, existing in a water absorption pipe bottom valve, are effectively solved, the times of replacing the bottom valve are reduced, the labor intensity of workers is reduced, the service life of apparatuses is prolonged, safety, high quality and efficient water drainage are realized, and better economic benefits are obtained.

Description

technical field [0001] The invention relates to the technical field of mine drainage systems, in particular to a jet water diversion device. Background technique [0002] The centrifugal pump used for underground drainage is installed above the liquid level of the water tank, and the water diversion of the suction pipe has become a difficult problem before the centrifugal pump is started. Because the bottom valve of the suction pipe has problems such as poor valve plate closure and water leakage, and the operation of the centrifugal pump needs to overcome the resistance of the bottom valve and consume a lot of energy, it is difficult to fill the suction pipe with water. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a jet water diversion device, which effectively solves the problem of diversion of centrifugal water pumps and achieves better economic benefits. [0004] The present invention is realized thro...
