PVC drainage check valve: promise that not a drop of water can flow back
In the drainage system, it is natural for water to flow downwards, but backflow is a nightmare for every user and engineering party. The backflow of sewage not only means property damage, but also represents health hazards and system failures. PVC drainage check valve is a one-way guard designed to end this problem.
PVC drainage check valve is a valve that automatically opens and closes the valve disc by relying on the flow of the medium itself. It only allows water to flow in one direction, and when the water flows forward, the valve disc opens under thrust; Once the water flow attempts to reflux, the valve disc will instantly close under the dual action of its own gravity and reflux pressure, physically cutting off the possibility of backflow.
Product advantages:
Excellent corrosion resistance: It has excellent corrosion resistance to inorganic acids, alkalis, and salts, and is particularly suitable for transporting industrial wastewater and domestic wastewater.
Smooth inner wall without blockage: low friction coefficient, smooth water flow, less prone to scaling and blockage, and extremely low maintenance in the later stage.
Ultra long service life: the normal service life can reach more than 50 years, with good anti-aging performance.
Lightweight and easy to install: The weight is much lower than that of metal valves, and it is connected with adhesive or rubber rings for convenient construction and high efficiency.
Core application scenarios:
Basement and low floor backflow prevention: During rainy seasons or when sewer pressure is too high, prevent sewage from flowing back from low points such as floor drains and toilets to avoid the tragedy of "flooding the golden mountain".
Sewage pumping station and drainage system: installed at the outlet end of the water pump to prevent water backflow in the pipeline during pump shutdown, which may cause impeller reversal or water hammer impact.
Odor and pest isolation: The baffle when closed can effectively block the odor in the sewer and prevent mice, cockroaches, etc. from entering the room through the pipeline.
Highway and airport drainage: In large-scale municipal drainage projects, ensure that rainwater only flows out and does not enter, ensuring the safety of infrastructure.
Installation precautions: Please make sure to confirm the direction indicated by the flow arrow on the valve body during installation, and it is strictly prohibited to install it upside down.
Choosing a qualified PVC drainage check valve is like buying a 50 year "anti backflow insurance" for your building drainage system. It not only safeguards the security of physical space, but also protects the cleanliness and tranquility of living environment.
