Description

Technical Field

[0001] This utility model belongs to the field of valve technology, and specifically relates to a valve with a steering function. Background Technology

[0002] Valves are control components in pipeline fluid transport systems, used to change the cross-sectional area of ​​the passage and the direction of medium flow. They have functions such as guiding, stopping, throttling, checking back, diverting, or overflowing and relieving pressure. Existing valves require their output or input ends to be fixedly connected to the pipeline for easy medium transport. However, the directions of the output and input ends of existing valves are fixed and cannot be adjusted according to usage requirements, which is inconvenient in practical use. Therefore, obtaining a valve with a steering function is crucial. Utility Model Content

Sealant is used to fill the space between the first internal thread and the first external thread.

[0008] The valve assembly also includes a control rod that passes through the valve housing and is fixedly connected to the valve core to control the opening and closing of the valve.

[0009] Two first connectors and two valve assemblies are provided, each connected to one of the first connectors via a first rotating connector. Each first connector further includes a fourth connector, which communicates with both first connectors. A second rotating connector is rotatably connected to the fourth connector. A second sealing ring is provided on the outer wall of the fourth connector and within the inner cavity of the second rotating connector.
