A vacuum suppresser is mainly used in municipal tap water pipe network secondary pressurized water supply equipment, to suppress the negative pressure is generated in the water supply system and equipment to keep the pressure of tap water pipe network balance.

Application range　
Residents living in high-rise buildings will often encounter problems with the lack of water pressure due to the lack of water. There are two main reasons for this result:
1, the water pressure is not enough, causing the water can not be sent to the top users.
2, since the water supply equipment is now usually the method of water supply for the user.
Therefore, when the user in a certain area, the region will make the pipeline pressure drop, a negative pressure, which affects the normal water supply of other residents.
 In order to effectively inhibit the network generated in negative pressure, in water supply equipment installed a vacuum suppressor can effectively avoid the negative pressure generated inside the water pipe, to solve the problem of water supply pipe, water supply equipment of negative pressure.
