"Breathing" in Biology Laboratory —— Talking about the importance of ventilation handle
In the biological laboratory, because of all kinds of complicated experiments and research work, a good air environment is very important for the smooth development of experiments. Among them, the ventilation device plays a very important role, and the ventilation handle as one of its core control components is indispensable.
First of all, let's know what a ventilation handle is. It is a kind of manual operation equipment for manually adjusting indoor air quality, which is generally installed on the exhaust duct or fume hood to realize effective regulation of exhaust air volume. The opening of the valve is adjusted by rotating or pushing the handle, so as to change the flow rate of gas discharged from the outdoor room and achieve the purpose of maintaining the balance of indoor and outdoor pressure difference.
For the laboratory, why do you need a high-quality ventilation handle?
I. Ensuring safety and health
Biological laboratories often involve the operation of toxic and harmful substances. In this case, if these pollutants cannot be eliminated in time and effectively, it will pose a great threat to experimenters. At this time, it is necessary to use the ventilation system to complete the purification task, and how to accurately control the ventilation rate is particularly important, which requires the use of ventilation handles for fine adjustment.
Second, save energy consumption
In the traditional sense, ventilation facilities mostly operate in full-time opening mode, and the power is large and the power consumption is considerable; However, if the opening and closing degree of the valve at the air inlet can be properly adjusted according to the actual demand (the so-called "throttling technology"), the energy consumption can be greatly reduced and the electricity bill can be saved, so this is one of the important reasons for introducing the adjustable ventilation handle.
Third, improve work efficiency
In some special occasions (for example, you need to go in and out of the room frequently, but you don't want to cause great disturbance every time you open the door), using a new model product with self-locking function can avoid the above problems to some extent. In addition, in the daily maintenance stage, products with easy-to-disassemble design features will be more convenient to clean the filter screen and other parts, thus improving the overall service life and stability performance.
In a word, it is very necessary and meaningful to "choose the right ventilation handle" no matter from which angle we look at this problem. Of course, in the selection process, we should also pay attention to check whether the manufacturer has relevant qualification certificates and whether the after-sales service system is perfect.
