1. Two outlet pipes with valves are connected to the gas-using device. The remaining one is the inlet pipe entrance, which should be connected with the introduction pipe of pipeline gas meter or the pressure reducing valve of bottled natural gas.
2, natural gas three-way valve is a "y" or "t" shaped gas shunt device. For the convenience of separate control, there should be a separate valve on each outlet pipe (the knobs of these valves usually have a distinctly different color from the body of the tee, e.g., red, yellow, or nickel-plated silver knobs to distinguish them from the brass body).
This provides a great deal of convenience for future loading and unloading, servicing, and troubleshooting. The use of industrial tees without valves is a violation of technical standards and installation codes.
Expanded Information:
p>1, three-way valve similar to the double-seat valve spool valve seat structure, but the three-way valve in a spool and the seat of the flow area between the spool increased, while the other spool and the seat of the flow area between the spool is reduced. In a double-seated valve, the flow area between the two spools and seats increases or decreases at the same time.
2, three-way air valve gas start and close, can only be selected by the positive action of the actuator and the reaction force to achieve, while in the two-seat valve gas start and close, can be directly through the valve body or spool and seat to achieve the reverse.
3. When the three-way valve is used in a control system that requires fluid matching, it can replace both gas on control valves and gas off control valves, thus reducing installation costs and space.
4, the three-way valve can also be used for bypass control places, such as a fluid needs to go through the heat exchanger heat exchange, another fluid does not need to go through the heat exchanger heat exchange, when the three-way valve is installed in the heat exchanger before the split three-way valve, when the three-way valve behind the installation of the heat exchanger with the tributary three-way valve.
