A multi-media separable and confluent ultra-high pressure nozzle

Abstract

The invention relates to a multi-medium ultrahigh pressure spray nozzle capable of dividing and combining streams. The ultrahigh pressure spray nozzle comprises a drill bit body, an outer seal cover, an inner seal cover, a rear seat, a first spray nozzle, a second spray nozzle, a second core tube, a first core tube, a first outer tube, a seal cover, a male connector, a third spray nozzle, a second outer tube, a third core tube, a cylinder barrel, a piston rod, a first spring, a sleeve, a front seat, a second spring and a connector; the drill bit body, the first outer tube, the male connector, the second outer tube and the connector are coaxially arranged and sequentially connected into a whole through threads; the first core tube is arranged inside the first outer tube, the rear end of the first core tube is connected to the rear seat in an inserted mode, the front end of the first core tube is connected with the seal cover in a sealed mode, and the seal cover is installed in the male connector in a sealed mode. According to the multi-medium ultrahigh pressure spray nozzle capable of dividing and combining the streams, the structure is exquisite and reasonable, multiple high-pressure media can be converted into high-energy jet streams to be sprayed out of the spray nozzles to impact and break original soft or low-strength soil, and dividing and combining work of the media can be conducted.

Description

technical field [0001] The invention relates to a multi-medium separable and converging ultra-high pressure nozzle, which belongs to the technical field of construction tools in engineering machinery. Background technique [0002] The structure of the existing multi-media high-pressure nozzles can already meet the three working media are high-pressure jets at the same time, but the three media are isolated from each other and do not communicate with each other, so they can only meet the requirements of one process. Before the actual construction, the hole must be formed first, and then a series of operations such as dismantling the drill pipe and replacing the drilling tool are required. When encountering the construction of large-diameter and super-depth piles, a lot of working time will be spent, which will affect the construction efficiency. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and to ...
