The invention belongs to the technical field of three-way pipes, in particular to a large-caliber three-way pipe. The large-caliber three-way pipe comprises a main passing pipe and a secondary passingpipe; the main passing pipe and the secondary passing pipe are connected through threads; a connecting projection is arranged on the secondary passing pipe; an air chamber is formed in the wall of the connecting projection; a thread hole is formed in the middle part of the connecting projection; an elastic metal thread tooth is arranged in the thread hole, and communicates with the air chamber through a first through hole; multiple air ways are formed in the pipe wall of the secondary passing pipe, and communicate through annular grooves; an arc metal elastic piece is arranged on the pipe wall of the secondary passing pipe; and a first spring is connected between the arc metal elastic piece and the pipe wall of the secondary passing pipe. The arc metal elastic piece is matched with the elasticity of the first spring to buffer the impact force of water currents to prevent the water currents from directly acting on the pipe wall of the secondary passing pipe, so that the service life ofthe secondary passing pipe is prolonged.
Description
technical field [0001] The invention belongs to the technical field of three-way pipes, in particular to a large-diameter three-way pipe. Background technique [0002] Whether it is urban civil tap water supply or industrial water supply, the tee pipe is indispensable as a connecting part of the pipeline, and in use, it is necessary to install the respective control valves on the main pipe and the branch pipe respectively, so that For the maintenance and replacement of pipelines, it provides guarantee for the water supply of each branch in stages. As a connecting piece, the tee pipe has high requirements on the firmness and sealing of the connection. The existing three-way pipes are all straight internal components, and there are no barriers in the middle. However, due to the straight interior, when liquids such as water rush into the bottom pipe from the main pipe, they cannot be divided immediately. The wall of the bottom pipe has a large impact, which will deform it aft...
