1、 Overview of Pneumatic Three way Internal Thread Ball Valve Products
The pneumatic three-way internal thread ball valve produced by Shanghai Yuhu Company is suitable for pure pipelines in food, beverage, pharmaceutical, chemical industries, as well as industrial environmental protection, water treatment, high-rise buildings, water supply and drainage pipelines. Pneumatic three-way threaded ball valves are divided into "L-shaped pneumatic threaded ball valves" and "T-shaped pneumatic threaded ball valves". The L-shaped valve is suitable for switching the flow direction of the medium and can connect two perpendicular channels, while the T-shaped valve is suitable for dividing, merging, or switching the flow direction of the medium. The double-layer valve stem packing meets the German leak testing requirements and can be inspected and repaired without removing the entire valve body after the system is depressurized. Any port of the pneumatic three-way internal thread ball valve can be used as an inlet without leakage, and can be made into an L-shaped or T-shaped channel according to the working conditions. This pneumatic internal thread ball valve is easy to install.
2、 Product features of pneumatic three-way internal thread ball valve
(1) The pneumatic three-way internal thread ball valve has two seat and four seat sealing structures, and the valve core hole has two structural forms: L-shaped and T-shaped. By controlling the rotation angle of the valve core and changing the connection state between the valve core hole and the pipeline port, different combinations of control for the three branch pipes can be achieved. Pneumatic three-way internal thread ball valve has a large flow capacity, which can control gas, liquid, and steam, and is more suitable for controlling high viscosity, fibrous granular fluids. It is also suitable for occasions with strict sealing requirements.
(2) The two seat sealed three-way ball valve has a compact structure, beautiful appearance, and good sealing performance. It can switch the flow direction of the medium in the pipeline. It can also connect or close two perpendicular channels.
(3) The four seat sealed three-way ball valve has a beautiful appearance and a compact and reasonable structure. It can not only switch the flow direction of the medium, but also connect the three channels to each other. At the same time, it can close any channel and connect the other two channels, flexibly controlling the merging or splitting of the medium in the pipeline.
(4) The T-shaped valve core hole can connect or switch three orthogonal pipelines to each other, playing a role in diversion or merging; The L-shaped channel connects two pipes that are orthogonal to each other. Cut off another channel to change the flow direction of the medium.
