The invention relates to a high-pressure gas combined valve for an adsorption type dryer. A compressed air source is connected with a main air inlet pipe. The main air inlet pipe is connected with a first branch air pipe and a second branch air pipe. The first branch air pipe is sequentially connected with a first two-position two-way electromagnetic valve and a first high-pressure air chamber. The first high-pressure air chamber is connected with a first adsorption tower and further connected with a first air outlet pipe. The first air outlet pipe is connected with a second two-position two-way electromagnetic valve. The second branch air pipe is sequentially connected with a third two-position two-way electromagnetic valve and a second high-pressure air chamber. The second high-pressure air chamber is connected with a second adsorption tower and further connected with a second air outlet pipe. The second air outlet pipe is connected with a fourth two-position two-way electromagnetic valve. The high-pressure gas combined valve has the beneficial effects that when the device is applicable to the manner that pressure is high or low, the environment temperature is high and work is done for a long time, the adopted electromagnetic piloted high-pressure gas combined valve controlled through pulse air supply solves the problems caused by heating after an original electromagnetic works for a long time, and the high-pressure gas combined valve is simple in structure, convenient to maintain and wide in usage pressure range.
Description
technical field [0001] The invention relates to the technical field of fluid control equipment, in particular to an electromagnetic pilot-operated high-pressure gas combination valve which adopts pulse gas supply to control the flow direction of high-pressure gas in an adsorption dryer. Background technique [0002] In the field of gas control, the electromagnetic pilot high-pressure two-position three-way valve is a common component, and it is an automatic basic component used to control the fluid. And break, used to adjust the medium flow direction, flow and other parameters, with different circuits to meet different control requirements. [0003] The on-off of the control air circuit of the existing electromagnetic pilot high-pressure two-position three-way valve is controlled by a two-position three-way solenoid valve. Natural gas or nitrogen dry purifiers often need to work continuously for more than 8 to 20 hours, and the solenoid valve is prone to overheating and coi...
