Problems solved by technology

[0003] The disadvantage of using a pneumatic diaphragm regulating valve for terminal control is that the pneumatic diaphragm regulating valve must have an instrument air source (compressed air is usually used)
For users who do not have an instrument air source, it is usually necessary to equip an air compressor and an air purification device, which not only increases the overall structure of the equipment, but also increases a source of failure

Abstract

This invention relates to the application of the magnetic valve in the hydrogen making device, on the hydrogen separator and oxygen separator of the electrolyzation hydrogen making device, there have the liquid level transmitter LT, pressure transmitter PT, temperature transmitter TT, liquid signal transformer LY, pressure signal transformer PY, temperature signal transformer TY, liquid level PLC, pressure PLC, temperature PLC, liquid level gas-filled film adjusting valve LV, pressure gas-filled film adjusting valve PV and temperature gas-filled film adjusting valve TV on them, the character is that the level gas-filled film adjusting valve LV, the pressure gas-filled film adjusting valve PV, the temperature gas-filled film adjusting valve TV are replaced by the level electric film adjusting valve, the pressure electric film adjusting valve, the temperature electric film adjusting valve respectively, and the volume of the electric film adjusting valve is small, which is convenient for the high integration of the complexes.

Description

(1) The technical field [0001] The invention belongs to the application of an electric thin film regulating valve in a hydrogen production device. (2) Background technology [0002] In water electrolysis hydrogen production equipment, there are three (generally only three) important analog control points, namely pressure, liquid level and temperature. So far, the pneumatic diaphragm control valve is used as the actuator for adjustment. The control principle diagram is as follows figure 1 shown. In the picture: 1-hydrogen separator, 2-oxygen separator, J1-liquid level bypass valve, J2-pressure bypass valve, J3-temperature bypass valve, LT-liquid level transmitter, PT-pressure transmission device, TE-platinum resistance, TT-temperature transmitter, LY-liquid level signal converter, PY-pressure signal converter, TY-temperature signal converter, LV-liquid level pneumatic diaphragm control valve, PV-pressure pneumatic diaphragm Regulator, TV-Temperature Pneumatic Film Regulato...
