Product Introduction
Steam bypass valve is A heat exchange device using superheated steam to heat reheated steam is used for regulating the temperature of reheated steam.
Product Advantage
The first function is to protect the main steam valve, so that the main steam valve is heated evenly, to avoid excessive thermal stress.Compared with the main steam pipe, the main steam valve is much thicker. When the main steam pipe is warm, if the main steam valve is opened directly, the main steam valve is easy to produce a lot of thermal stress due to uneven heating.If the warm pipe first open its bypass valve, such as the end of the warm pipe and then open the main steam valve, the main steam valve heating is more uniform, the thermal stress is very small.
The second role is to protect the steam pipeline system, to avoid the occurrence of water shock, vibration and other phenomena caused by a large number of steam suddenly entering the pipeline when warming the pipe.
The third function is ease of operation.In the process of pipe warming, the pressure gap between the front and back of the main steam valve is large, leading to the operation of the main steam valve is difficult.The use of open bypass on the one hand to warm the pipe, so that the valve is easy to open, reduce the valve sealing surface wear. And the bypass valve flow interface is small, easy to control the warm pipe speed.
Why choose us
The steam pipe needs a warm pipe when it passes steam, and the warm pipe process needs to be carried out slowly.Because the operation of the large valve is very inconvenient, once opened, there will be a large number of steam into the pipeline, which will cause water shock, vibration and other phenomena, serious damage to the pipeline and system.In order to ensure the stability and safety of the warm pipe process, a relatively small valve is set next to the big valve, and the small valve is used to control the steam entering the pipe, so as to achieve the purpose of slowly sending the steam warm pipe. Open the main steam valve when the pipe is warmed up
