Three-way connector capable of automatically cutting off liquid leakage

Abstract

The invention discloses a three-way connector capable of automatically cutting off liquid leakage applied to the field of chemical engineering or pollution discharge. The three-way connector comprises a connector body, a valve element, an elastic assembly and a pneumatic assembly. The connector body comprises a main connecting pipe and two branch connecting pipes, gas grooves are formed in the pipe walls of the two branch connecting pipes, and openings of the gas grooves are located in the end faces of the branch connecting pipes. The elastic assembly applies acting force to the valve element to drive the valve element to keep a normally-closed state. The pneumatic assembly comprises a cylinder body, an inflation nozzle and a force application end. The cylinder body is fixed in an inner cavity of the connector body, the gas grooves are communicated with the cylinder body, the inflation nozzle is used for inflating gas into the gas grooves and the cylinder body, and the force application end can gradually move towards one side of the valve element along with increase of the pressure of the gas inflated into the cylinder body through the inflation nozzle. When the three-way connector is in use, after the cylinder body is filled with sufficient gas through the inflation nozzle, when a gap is formed between a flow dividing pipeline and the three-way connector, the cylinder body leaks gas, the valve element is closed, and therefore liquid leakage can be blocked.

Description

technical field [0001] The invention relates to the field of three-way joints, in particular to a three-way joint which can automatically cut off the flow of liquid leakage. Background technique [0002] Tee joints are often used in piping systems, which play the role of diversion, and can distribute the liquid in the main pipeline to the subsequent distribution pipelines. [0003] In some chemical fields or sewage fields, due to the influence of the working environment, the pipeline may be in a vibrating environment for a long time, especially the shunt pipeline, which has a small diameter, so the vibration is particularly obvious. The shunt pipe is usually connected to the tee joint by bolts. Therefore, under the condition of long-term vibration, the bolt may become loose, and then the connection between the shunt pipe and the tee joint may become loose, that is, the joint at the interface between the two may become loose. If there is a gap, the liquid will leak out from ...

Problems solved by technology

The shunt pipe is usually connected to the tee joint by bolts. Therefore, under the condition of long-term vibration, the bolt may become loose, and then the connection between the shunt pipe and the tee joint may become loose, that is, the joint at the interface between the two may become loose. If there is a gap, the liquid will leak out from the gap. If the staff does not stop it in time, the liquid will continue to leak. Even because the shunt pipe is still shaking, it may cause the shunt pipe and the tee joint to fall off. situation, further exacerbating the leakage of liquid
