Abstract

The present invention relates to a combined high-pressure exhaust valve, belonging to the field of high-pressure system control technology. It is mainly characterized by that in the centre of exhaust valve body a three-way gas channel is set, two ends of straight channel are respectively equipped with one-way seal valve, in another channel interior an adapter is mounted; in which two one-way seal valves respectively adopt valve core component and spring mounted in the valve seat, and utilize adapter body to fasten them into the exhaust valve body interior; in the side surfaces of its two one-way seal valves are respectively set other two one-way seal valves, said other two one-way seal valves can respectively utilize two throttle valves to fasten the valve core component and spring into the exhaust valve body interior.

Description

technical field [0001] The invention relates to a combined high-pressure exhaust valve, which is installed at the outlet of a dryer group, and is mainly used to control the gas flow direction of the outlet gas of the dryer in a high-pressure adsorption drying device, and to adjust the ratio of the gas supply volume and the regeneration gas volume. The function belongs to the technical field of high voltage system control. Background technique [0002] Adsorption drying device is one of the simplest and most commonly used devices in gas purification. This drying device is generally composed of two parallel and independent dryers. In order to enable the two dryers to perform adsorption and regeneration cycle To work, the desiccator in the regenerating state must be fed with clean and dry gas to regenerate and blow it off, so as to achieve the effect of accelerating regeneration. Generally, the regeneration gas of the adsorption drying device adopts the clean and dry air that ...
