What are the positive and negative effects of the regulating valve?

New furnace wall insulation, low cost of boiler room

The outer wall of the boiler uses light insulation material, and the outer cover is model slab, which has good heat insulation effect. There is no brick in the inner and outer wall of the boiler, and its no steel frame structure can greatly reduce the weight of the boiler. The total weight of the angle tube furnace is equivalent to 1/2 of the same type of bulk boiler. The bearing capacity of the boiler foundation is reduced by more than half, and the body height is also reduced. The height of the whole boiler room can save a lot of building materials, which greatly reduces the total cost of the boiler room.

The positive reaction of the regulating valve refers to the positive action when the upper part of the diaphragm head is filled with air and the push rod moves downward, compared with the actuator of the pneumatic diaphragm regulating valve. The lower air intake and the upward movement of the push rod are called reaction.

The air opening air closing of the regulating valve is relative to the whole regulating valve. With the increase of signal, the valve is gradually opened as an air opened valve, and with the increase of signal, the valve is gradually closed as an air closed valve. When there is no signal, the air opening valve is closed and the air closing valve is fully open.
