Problems solved by technology

However, this design needs to control the 2′ coils of each valve. If the solenoid valve, gas source pipeline, and cable costs are calculated, the control cost of each valve is about 5,000 yuan or more. If there are many valves or locations far, the overall cost will be very expensive

Abstract

The embodiment of the invention discloses a control device. A manual changeover valve is additionally arranged between a control valve and air cylinders of a plurality of pneumatic valves, secondary changeover can be conducted to air ways of the air cylinders of the plurality of pneumatic valves through the manual changeover valve in the on state of the pneumatic valve so as to realize the simultaneous control on the air cylinders of the plurality of pneumatic valves, one or more valves can be separately switched off without the need of switching off all the valves or stopping a system when a part of technological pipeline does not work. Compared with the prior art, according to the control device, the manual changeover valve is not required from being additionally arranged and electromagnetic valves are not separately used, so that the arrangement of a control line using a control coil to work can be avoided while the usage amount of coils can be reduced, therefore the cost can be lowered. The embodiment of the invention further discloses a pneumatic system.

Description

technical field [0001] The invention relates to the technical field of boilers, more specifically, to a control device and a pneumatic system. Background technique [0002] For large-scale process systems, due to the complexity of the process, it is necessary to set pneumatic valves on the pipeline 2' to control the fluid in them. Some of the valves need to be opened or closed at the same time when the system is running. Among them, the pneumatic valve is closed separately to cut off the fluid in it. The commonly used control element for pneumatic valves is the two-position five-way solenoid valve 3', such as figure 1 As shown, the two-position five-way solenoid valve 3' has two coils in total. When the coils are charged respectively, the switching of the gas circuit can be controlled, so that the cylinder 1' driving the pneumatic valve can supply or exhaust air, so as to realize the opening or closing of the pneumatic valve. valve. When the coil D1 is electrified, the ai...
