When the Pressure in the system drops to form a vacuum, the induction device of the vacuum breaking valve will detect this change. Once the vacuum degree reaches the set value, the valve will automatically open under the action of spring force, gravity or external air pressure to allow external air to enter the system, destroy the vacuum state, and restore the Pressure balance in the system; When the system Pressure returns to normal, the valve will close automatically.

Product Features

Quick response: able to detect vacuum changes within the system in a short period of time and promptly activate, quickly breaking the vacuum and preventing damage to the system due to excessive vacuum.

High reliability: With a simple structure and no complex electronic components or control systems, it reduces the possibility of failures and can operate stably in harsh working environments.

Easy maintenance: With fewer components, it is easy to disassemble and repair, reducing maintenance costs and time.

Strong universality: can be used for various systems and media such as water, steam, gas, etc

Applicable working conditions

1. Water supply and drainage system: installed on the suction port or outlet pipe of the water pump. When the water pump suddenly stops running, it prevents the generation of vacuum in the pipeline, avoids the occurrence of water pump reversal and water hammer, and protects the water pump and pipeline system.

2. Hot water heating system: In the hot water circulation system, when the water pump stops working, the vacuum breaker valve can prevent the water in the system from flowing back due to negative pressure, ensuring the normal operation of the system,

3. Fire protection system: used on the suction and outlet pipes of the fire pump to ensure that the fire protection system can work normally in emergency situations and prevent vacuum problems from affecting the fire water supply.

4. Industrial production process: In some industrial production processes with strict requirements for vacuum degree, such as chemical, pharmaceutical, food and other industries, the vacuum breaking valve can be used to maintain the Pressure stability of the system and ensure the normal operation of the production process.
