Product Description

The three-in-one check valve is a valve device that integrates multiple functions. It is mainly used in pipeline systems to prevent medium backflow, balance pressure or protect equipment safety. The following is a detailed introduction about it:
1. Basic functions
The three-in-one check valve usually combines the following three functions:
- Check function: prevent the medium (liquid, gas, etc.) from flowing backwards to avoid damage to equipment such as pumps and compressors caused by backflow.
- Pressure reduction/pressure relief function: when the system pressure exceeds the set value, it automatically releases part of the pressure to protect pipelines and equipment.
- Isolation function: cut off the flow of medium during inspection or maintenance, similar to the function of a stop valve.
2. Structural features
- Valve body design: usually adopts a compact structure, integrating multiple functional components (such as valve disc, spring, pressure relief device, etc.).
- Material selection: cast iron, stainless steel, brass and other materials are selected according to the characteristics of the medium (corrosiveness, temperature, pressure).
- Drive mode: mostly automatic operation (depending on medium pressure or spring force), some models can be manually controlled.
3. Application scenarios
- Water supply and drainage system: prevent water hammer effect or backflow when the water pump stops.
- Heating, ventilation and air conditioning (HVAC)**: balance the pressure of hot and cold water systems.
- Industrial pipelines: protect equipment in chemical, oil and natural gas pipelines.
- Fire protection system: ensure one-way water supply in the fire water network.
4. Advantages
- Space saving: three functions in one, reducing the number of valves in the pipeline.
- Cost-effectiveness: installation and maintenance costs are lower than multiple independent valves.
- High reliability: integrated design reduces the risk of leakage.
