Double-channel air ventilation and purification device and valve assembly thereof

Abstract

The embodiment of the invention relates to a dual-channel air ventilation and purification device and a valve assembly thereof, relates to the technical field of air purification, and mainly aims at providing the dual-channel air ventilation and purification device which is multifunctional and convenient to operate and the valve assembly of the dual-channel air ventilation and purification device. According to the main technical scheme, the valve assembly comprises a valve base body, wherein the valve base body is provided with a ventilation valve port, a purification valve port and a negative pressure valve port; a ventilation valve core body arranged at the ventilation valve port; a purification valve core body arranged at the purification valve port; a negative pressure valve core body arranged at the negative pressure valve port; and an operating part used for jointly controlling the ventilation valve core body, the purification valve core body and the negative pressure valve core body. Compared with the prior art, in the operation of the ventilation mode, an electrically-controlled purification valve and an electrically-controlled negative pressure valve do not need to be operated any more, and the operation process is convenient and fast.

Description

technical field

[0001] The embodiments of the present invention relate to the technical field of air purification, in particular to a dual-channel air ventilation and purification device and a valve assembly thereof. Background technique

[0002] In response to wars, natural disasters, and production accidents, it is necessary to consider air pollution more comprehensively to provide personnel with a clean living space.

[0003] In the polluted air environment with particle pollutants in the external environment, a particle purifier can be used to purify the air, and the filtered clean air is used as the air source inside the isolation tent. In a toxic and harmful environment, it is necessary to use an absorption purification device to purify the air, absorb polluted gases, and use the clean air after absorption and purification as the air source inside the isolation tent.

[0004] Among them, in order to meet all-round accident prevention and control, multiple different ai...
