Problems solved by technology

[0003] In view of this, in order to solve the problem of how to adapt the air volume valve to the production time and duty time of the clean workshop, the present invention proposes a constant air volume valve with duty mode. According to the actual installation and production experience, fine automatic control is not required, so only It is only necessary to have two kinds of openings for the air valve of the relevant system, and it is not necessary to adjust t

Abstract

In order to solve the problem of how to enable an air volume valve to adapt to the production time and the duty time of a clean workshop, the invention provides a constant air volume valve with the duty mode. Fine automatic control is not needed according to actual installation and production experience, so that only air valves of a related system need to have two opening degrees, a conventional electric air valve is not needed for adjustment, and the manufacturing cost is reduced; through cooperation of a control mechanism and an actuating mechanism, the constant air volume valve has two modes, and the gear of the constant air volume valve is adjusted through a remote signal; and meanwhile, due to the fact that only two fixed gears are arranged, the problems of inaccurate opening degree and inaccurate air volume caused by system signal fluctuation can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of air volume valves, more specifically, to a constant air volume valve with duty mode. Background technique [0002] In the production practice of pharmaceutical companies, due to factors such as production capacity and production scheduling cycle, usually the clean production workshop can maintain a relatively positive pressure, that is, the static air pressure value in the clean workshop needs to be slightly greater than the air static pressure value in the outdoor environment to ensure The clean room will not damage or change the air purification level status inside due to the inflow of outdoor air. 24-hour production cannot be achieved in the clean workshop. Generally, the air-conditioning box will adjust the system air volume of the ventilation duct according to the needs of the environment. Generally, an electric control valve is installed at the output end of the ventilation duct to automatically adj...
