How many valves are equipped with an atmospheric fixed-bed intermittent gas furnace?

A gas furnace is equipped with a dust collector, a waste boiler and a gas scrubbing tower. The process configuration is 11 hydraulic valves. respectively: Blowing valve, safety damper valve, up valve, down valve, air supply valve, chimney valve, gas main valve, steam main valve, upward steam valve, downward steam valve, air suction valve. Seat plate valves should be used as little as possible.

Hydraulic valve Hydraulic control valve (hydraulic valve for short) is a control component in the hydraulic system. It is used to control the pressure, flow and flow direction of the fluid in the hydraulic system, so as to meet the different action requirements of various actuators. Hydraulic control valves can be divided into three categories: directional control valves, pressure control valves and flow control valves according to their functions. Correspondingly, three basic circuits can be composed of these valves.: Direction control loop, pressure control loop and speed control loop. According to different control methods, hydraulic valves can be divided into ordinary hydraulic control valves, servo control valves and proportional control valves. According to different installation forms, hydraulic valves can also be divided into several types such as pipe type, plate type and cartridge type. Hydraulic valve is an automation component operated by pressure oil. It is controlled by the pressure oil of the pressure distribution valve. It is usually used in combination with the electromagnetic pressure distribution valve and can be used to remotely control the on and off of the oil, gas and water pipeline systems of hydropower stations. 　　It is used to reduce and stabilize the oil pressure in a certain branch of the system. It is often used in clamping, control, lubrication and other oil circuits. There are direct-acting types and pilot-operated types, and the pilot-operated type is mostly used.

The number of valves is determined by the design needs of the system. Generally, there are about 15 hydraulic valves in a single furnace system.

Our single-furnace system has 14 hydraulic valves, and seat valves are used in all corners. I don’t know what someone above means when they say no seat valves are needed.

Thank you to the senior upstairs for providing valuable data!

Some of our furnaces have 14 hydraulic valves, 3 gate valves, 1 butterfly valve. This post was last edited by qq312 on 2009-2-12 13:25 ]
