What is Sink Trap
The water bend is in the sanitary ware drain or sanitary ware inside a certain height of the water column, to prevent the drainage piping system in the gas fled into the interior of the accessory, the water bend within a certain height of the water column is called the water seal.
The water bend is one of the main accessories of the drainage pipe in the building, some sanitary ware construction has a water bend (such as sitting toilet), the construction does not have and industrial wastewater receiver and domestic sewage piping or other possible harmful gases may be generated when the drainage pipe connection, must be set in the drain below the water bend.

Types of Sink Trap
S-shaped Sink Trap
For vertical connection with the drainage pipe.
P-shaped Sink Trap
For the horizontal right-angle connection with the drain pipe or drain pipe in the place.
bottle Sink Trap
Bottle bend and with the ventilation device of the water bend is generally located in the washbasin or washbasin and other sanitary ware discharge pipe, the form is more beautiful.
Water storage box and S-shaped Sink Trap
The same, more flexible installation, easy to clean out.
Advantages and disadvantages of sink Trap
Advantages:
good airtight
The "U" type water seal of the sink trap can effectively prevent odor, noise and foreign matter from entering the room, to ensure that the indoor air is clean.
Stable water seal
The U-shaped design of the sink trap can form a certain height of the water seal to ensure that the sealing performance of the drainage pipe, in the system design has a certain degree of fluctuations in the more stable.
Preventing dirt deposits and reducing the blockage rate
The curvature of the sink trap can slow down the water flow rate, reduce the blockage rate of deposits and dirt, and reduce the number of times and costs of pipe cleaning.
Disadvantages:

The "U" shape design of the storage elbow will take up some space, which is deeper than other types of elbows, and is not conducive to the design and installation of drainage pipes.
The height of the water seal in the storage elbow may change after long-term use, and for some infrequently used pipes, periodic maintenance or replacement may be required.

The application of Sink Trap
Water storage bend is widely used in a variety of piping systems, especially in industry, construction, agriculture and other fields.
Industrial piping systems
Industrial piping systems, usually need to transport large amounts of liquid or gas. These media in the flow process, will produce a large water velocity and pressure changes, resulting in pipeline damage, excessive noise, water hammer and other problems occur.
At this time, you can increase the number of water storage bends to divert, slow down the speed of water flow, reduce the pressure changes inside the pipeline, so as to protect the safe and stable operation of the pipeline system.
Building Piping Systems
Building piping systems are usually required to transport a variety of water supply, drainage, heating and other media. During the flow of these media, large changes in water velocity and pressure can also occur, which can lead to pipe wear, excessive noise, water hammer and other problems. At this time, you can increase the number of water storage bends to slow down the water flow rate, reduce the pressure change inside the pipe, so as to protect the safety and stable operation of the pipeline system.
Agricultural irrigation system
Agricultural irrigation systems usually need to transport a large amount of water flow. These water flows in the flow process, but also produces a large water velocity and pressure changes, resulting in pipeline damage, excessive noise, water hammer and other problems. At this time, you can increase the number of water storage bends to divert the water flow, slow down the water flow speed and reduce the pressure changes inside the pipe, thus protecting the safety and stable operation of the piping system.
