In everyday life and in production, special devices are often used that allow, if necessary, adding one substance to another dropwise. These devices are called drip funnels. They can be divided into chemical, domestic and industrial. Depending on the purpose, funnels are made from various materials.
Types of dropping funnels
A dropping funnel for chemical functions is made from chemical glass material. It is very durable and protects against chemicals.
Industrial drip funnel is made of plastic, glass and metal.
Home funnels can be made of plastic and glass.
The most important thing is that the funnels must be strong, not breaking, you need to constantly clean them.
The dropping funnel is light in weight, with a thin wall and an elongated end.
Beginning of work
Before starting work, it is absolutely necessary to lubricate the funnel valve with Vaseline. This allows you to open it without much effort. Otherwise, if the crane opens tightly, the funnel may break.
To make drops from the funnel flow evenly, a special funnel with a nozzle is used. In it immediately after the crane is an expanded part. She goes into a narrow pipe. The liquid first flows into the expansion, only then into the tube.
Air conditioners with drip funnel with siphon
In the modern world, air conditioners are often used in organizations, enterprises, and homes. Typically, the outdoor units of split systems are installed on the facade of buildings and liquid from the pipe, condensate, drains onto the street, onto the heads of passers-by, or into some kind of container. Especially in hot weather.
To solve this problem, a dropping funnel with a water lock was created. It is suitable for any type of air conditioner. The drainage from the air conditioner is connected to the jet gap to the sewer system. The siphon must necessarily have an odor-locking function, which starts to work when the air seal dries. This function is very important, because due to the possible drying of the shutter in the room where the air conditioner is located, unpleasant odors may appear. The funnel allows you to discharge the resulting condensate and drainage into the sewer manhole.
This funnel is designed to discharge a small and irregular amount of fluid. This function protects against unpleasant odors from the sewer system.
A dropping funnel for air conditioners is made of polypropylene material. The height of the water seal is sixty millimeters.
