High pressure and mass flow pneumatic electromagnetic switch valve

Abstract

The invention provides a high pressure and mass flow pneumatic electromagnetic switch valve. The high pressure and mass flow pneumatic electromagnetic switch valve is provided with two air inlet passages, two exhaust passages, an electromagnet unit, a valve sleeve unit, a valve body unit, and a valve core unit; the two air inlet passages are connected with gas cylinders of different pressures, andthe two exhaust passages are connected with the external environment; the valve body unit moves within the valve sleeve unit under the action of the electromagnet unit and gas pressure of the gas cylinders to periodically open and close the air inlet passages and the exhaust passages, so that gas in the gas cylinders enters into a pneumatic engine through a exhaust port.

Description

technical field [0001] The invention designs a high-pressure pneumatic control technology, in particular a high-pressure and large-flow pneumatic electromagnetic switch valve. Background technique [0002] Conventional pneumatic components on the market generally have a working pressure of about 1MPa and a small flow rate, while for high-pressure pneumatic engines, the gas pressure is generally above 5MPa, and the requirements for the response time and gas flow rate of the control components are relatively high. [0003] Generally speaking, the working pressure of pneumatic actuators is around 1MPa. For vehicle-mounted pneumatics, due to the limited power energy, the pressure of the gas tank is generally high, while the conventional pneumatic system is decompressed by a pressure reducing valve before the intake air. And the principle of the decompression method is throttling and decompression, and the energy loss is relatively large. The high-pressure multi-pneumatic engine...

[0003] Generally speaking, the working pressure of pneumatic actuators is around 1MPa. For vehicle-mounted pneumatics, due to the limited power energy, the pressure of the gas tank is generally high, while the conventional pneumatic system is decompressed by a pressure reducing valve before the intake air. Moreover, the principle of the decompression method is throttling and decompression, and the energy loss is relatively large.
