Product Desription
The vacuum breaker is also called vacuum relief valve
1. Product Description:
A PP (Polypropylene) vacuum relief valve is a type of valve designed to protect equipment or systems from excessive vacuum pressure. It is typically constructed using polypropylene material, which provides excellent chemical resistance and durability. The valve consists of a body with an inlet and outlet, and a movable disc or diaphragm that opens or closes the flow path based on the pressure conditions.
2. Application:
The PP vacuum relief valve is commonly used in various industrial applications where the control and regulation of vacuum pressure are necessary. It is primarily employed in systems that handle liquids or gases and may encounter vacuum conditions. Some typical applications include:
- Chemical Processing: PP vacuum relief valves are used in chemical plants and laboratories where chemicals are stored, processed, or transferred under vacuum conditions.
- Petrochemical Industry: Vacuum relief valves are utilized in petrochemical refineries and oil and gas processing facilities to protect equipment such as storage tanks, reactors, and distillation columns from excessive vacuum pressures.
- Pharmaceutical Manufacturing: The pharmaceutical industry often employs vacuum systems in various processes such as distillation, drying, and filtration. PP vacuum relief valves help maintain the desired vacuum levels and prevent equipment damage.
- Food and Beverage Processing: Vacuum relief valves are used in food and beverage processing plants to control vacuum levels during packaging, preserving, and other processing operations.
- Water Treatment: PP vacuum relief valves can be found in water treatment plants to regulate vacuum pressure in systems such as vacuum filters, evaporators, and degassers.
3. Where it is used:
PP vacuum relief valves are utilized in a wide range of industries and applications. Some specific areas where these valves may be used include:
- Storage tanks: Vacuum relief valves are installed on storage tanks for various substances, including chemicals, petroleum products, and food ingredients, to prevent implosion or damage due to excessive vacuum conditions.
- Process piping systems: They are incorporated into process piping systems to control and maintain vacuum pressure within specific ranges.
- Vacuum pumps and compressors: Vacuum relief valves can be installed on the inlet or outlet of vacuum pumps and compressors to protect them from damage caused by excessive vacuum levels.
- Vacuum chambers: These valves are used in vacuum chambers or systems to regulate the vacuum pressure during experiments, manufacturing processes, or scientific research.
Overall, the PP vacuum relief valve is an important component in industries where vacuum conditions need to be controlled, ensuring the safe and efficient operation of equipment and systems.
