Features of Pneumatic Flexible Wastewater Trapping Device
1. Clear-day stormwater interception
Gravity Flow: Direct urban wastewater flows into the sewage pipeline, achieving dry flow wastewater entry. The flexible pneumatic control device on the intercepting pipeline opens, directing dry flow wastewater into the main sewage pipeline; during rainfall, the rainwater from the diversion well enters the intercepting main pipeline, while clean rainwater flows into the downstream municipal rainwater pipeline or the nearest natural water body.
2. Rainwater Initial Diversion
As initial rainwater enters the stormwater well, the flexible interception device opens to prevent the direct entry of initial rainwater into the river. Once the water level reaches the set height, the flexible interception device automatically closes to intercept the flow and direct the rainwater to the river channel.
When the liquid level in the diverging well is below the set level, the flexible pneumatic cutoff device on the intercepting pipe activates, allowing wastewater to be discharged into the sewage network.
Additionally, the Myuan pneumatic equipment is equipped with the Myuan-iSCADA cloud-based intelligent control system, enabling the flexible interceptor to function unmanned as well as remotely.

Flexible Pneumatic Flow Control Device Product Brief:
The Flexible Pneumatic Shutoff Device is a valve product that absorbs superior technology. This series of devices has no sealing points, ensuring no leakage occurs; it is resistant to particle erosion and won't clog when transporting fibrous liquids. Its performance is comparable to imported products, and it offers advantages such as short lead times, reasonable pricing, and attentive service. The Flexible Pneumatic Shutoff Device is also capable of handling dense mixtures or liquids of rainwater and wastewater separation.
The flexible pneumatic cutoff device's rubber sleeve is in a tensioned state due to fluid pressure. The sleeve's length and diameter do not change due to fluid pressure, as the inner layer of reinforced fabric, arranged at an angle, balances the axial and radial pressure. When the control medium enters the cavity between the sleeve and the valve body, the sleeve deforms and cuts off the flow under the medium pressure.
The flexible pneumatic shutoff device connects the cavity between the rubber sleeve and valve body to the atmosphere when the control medium is not input, and the rubber sleeve is in a tensioned state outward due to fluid pressure. Because the tube sleeve contains a reinforcing fabric layer arranged at an angle, it balances the axial and radial pressures, thus the length and diameter of the tube sleeve do not change due to fluid pressure. When the control medium enters the cavity between the tube sleeve and valve body, the tube sleeve deforms and shuts off the flow under the pressure of the medium.
Flexible pneumatic shutoff device: Utilizes a rubber sleeve with reinforced fabric, capable of withstanding high-frequency opening and closing operations, resistant to acids, alkalis, and chemical media, and boasts an extended service life.
Installation Simple: Valves can be installed in any direction, no need to clean pipes, and replacement is quick and easy once the rubber sleeve is damaged.
Convenient control: Local or remote automated operation control can be achieved as needed.
