What is the principle of floor drain?
Principle of eccentric block floor drain: eccentric block floor drain is sealed by gravity eccentric principle to resist the volatilization of odor gas.
Principle of eccentric block floor drain: eccentric block floor drain is sealed by gravity eccentric principle to resist the volatilization of odor gas. The floor drain uses a pin to fix the sealing gasket. From its structure, it can be seen that the disadvantages of this type of floor drain are that the seal is not tight, and the pin is easy to be damaged, which is also the reason for the failure of deodorization effect.
Principle of magnet type floor drain: This type of floor drain is mainly sealed by the magnetic force of the magnet. When the magnet type floor drain is used for a period of time, more metal impurities will be adsorbed on the surface of the magnet, which will cause the sealing gasket to open. This leads to poor deodorization effect. As the characteristics of the magnet itself will also be affected by the earth's magnetic field, the magnetic force will be reduced.
Principle of mechanical floor drain: the sealing gasket is opened and closed mainly by using the principle of reverse gravity. Compared with the above four types of floor drains, this type of floor drain has no obvious shortcomings. There is no need for water seal or external force such as spring and magnet.
Principle of spring type floor drain: spring type floor drain can be divided into two types: upward spring type and downward spring type. Press and hold the spring type pressing plate, the cover plate will spring up, and press again to return to its original position. The spring down type is combined with the gasket at the bottom of the spring expansion seal core for sealing.
