What Valves Are Used for Drainage Pipes?
1. Valve and set the choice of components The valves used on the water supply pipeline, generally according to the following principles. ● the diameter of the pipe is not greater than 50 mm, it is appropriate to use the globe valve, pipe diameter greater than 50 mm gate valve, butterfly valve. ● the need to adjust the flow, water pressure, it is appropriate to use the regulating valve, disconnecting valve. ● requires a small resistance to water flow (such as pump suction pipe), it is appropriate to use the gate valve. ● the water flow needs two-way The two-way flow of water should be the gate valve , butterfly valve , can not use the globe valve. ● the installation space of small parts should be used butterfly valve, ball valve. ● in the often open, close the section of the pipe, it is appropriate to use the globe valve . ● the larger diameter of the water pump discharge pipe should be selected multifunctional valve. 2.
