Problems solved by technology

[0005] The present invention can solve the problem that the existing three-way valve usually has poor sealing effect, inconvenient installation and disassembly, and the length of the valve body is usually fixed, so the protruding length of the valve body cannot be adjusted, which is not conducive to the follow-up of the pipeline. At the same time, when the existing three-way valve is connected to the pipeline, the connection effect is poor, and the inside of the pipeline cannot be supported and fixed, and the pipeline is prone to deformation under force, resulting in poor sealing effect of the pipeline and affecting the transportation safety of the pipeline. and other difficult problems

Abstract

The invention relates to a three-way valve. The three-way valve comprises a valve body, a telescopic pipeline and a fixed pipeline; the valve body is of a cylindrical structure; a cavity is formed inside the valve body; the telescopic pipeline is installed inside the cavity; a through hole is formed in the middle of the lower end of the valve body; the through hole communicates with the cavity; and the fixed pipeline is installed at the lower end of the through hole. The three-way valve can solve the problems that the existing three-way valve usually has a poor sealing effect and is inconvenient to install and disassemble, and the length of the valve body is usually fixed, so that the extension length of the valve body cannot be adjusted, which is not conducive to the subsequent pipeline use, and at the same time, when the existing three-way valve is connected to the pipeline, the connection effect is poor, and the interior of the pipeline cannot be supported and fixed, and the pipeline is easily deformed due to stress, resulting in a poor sealing effect of the pipeline and affecting the transportation safety of the pipeline.

Description

technical field [0001] The invention relates to the field of three-way valves, in particular to a three-way valve. Background technique [0002] Pipeline transportation has developed into one of the important modes of transportation in my country's transportation system, and has attracted the attention of people from all walks of life. Pipelines can not only transport liquids but also gases, which provides people with a convenient life. As an important structure of pipeline transportation, valves play no role. It can be replaced, wherein the three-way valve body also plays an important role in the manufacturing process, but the existing three-way valve body has some shortcomings in the process of use. [0003] At present, when the existing three-way valves are used, the following defects usually exist: 1. The existing three-way valves usually have poor sealing effect, inconvenient installation and disassembly, and the length of the valve body is usually fixed. The protruding...
