The pneumatic manifold, also known as the manifold, is the main supporting equipment of the boiler and is used to distribute the steam generated during boiler operation to various pipelines. The manifold is a pressure-bearing device and is a pressure vessel. The main function of the manifold is to distribute steam, so there are a number of valve seats on the manifold connecting the boiler's main steam valves and steam distribution valves, so that the steam in the manifold can be distributed to the various places where it is needed.
Expanded Information:
The main pressurized components of the manifold are: the steam distribution valve seat, the main steam valve seat, Safety valve seat, trap seat, pressure gauge seat, temperature gauge seat; head, shell, flange materials are Q235-A/B, 20g, 16MnR, specifications for the ф159-ф1500, the working pressure of 1-2.5MPa, the operating temperature: 0 ~ 400 ℃.
The working medium of air separation block is steam, hot and cold water, compressed air. When the medium is steam, it should be designed in accordance with the provisions of the "Pressure Vessel Regulations", and determine the cylinder diameter, material and thickness. Cylinder diameter should be 2-2.5 times the diameter of the largest receiver pipe, generally determined by the fluid flow rate in the cylinder, material 10-20 # seamless pipe, Q235B, 20g, 16MnR plate rolled, the number of takeovers by the engineering design decision.
