The pneumatic flexible intercepting device is a standardized product, with pipe diameters ranging from DN400 to DN1500. The housing is made of SUS304 material or corrosion-resistant carbon steel. The system includes the main body of the flexible intercepting device, composite rubber sleeve, level gauge, water quality monitor, video system, and intelligent control system, and can also be equipped with a solar power supply system to ensure the cost-effectiveness and operational reliability of the system.
Flexible Pneumatic Shutoff Device Product Description:
Flexible pneumatic shutoff devices are valve products that absorb superior technology. This series of flexible pneumatic shutoff devices has no sealing points, ensuring no leakage; it is resistant to particle erosion and will not clog when transporting liquids containing fibers. Their performance is comparable to imported products, and they offer advantages such as short delivery times, reasonable prices, and attentive service. The flexible pneumatic shutoff devices are also suitable for handling dense mixtures or liquids of rainwater and wastewater separation.
The flexible pneumatic shutoff device's rubber sleeve is under tension due to fluid pressure. Because the sleeve contains an angle-arranged reinforcing fabric layer inside, it balances the axial and radial pressure, so the sleeve's length and diameter do not change with fluid pressure. When the control medium enters the cavity between the sleeve and the valve body, the sleeve deforms to cutoff the flow under the medium pressure.
The flexible pneumatic cutoff device connects the cavity between the rubber sleeve and the valve body to the atmosphere when the control medium is not input, and the rubber sleeve is in a tensioned state due to the fluid pressure. Because the sleeve contains a layer of reinforced fabric arranged at an angle, it balances the axial and radial pressures, so the length and diameter of the sleeve do not change due to fluid pressure. When the control medium enters the cavity between the sleeve and the valve body, the sleeve deforms to cutoff the flow under the medium pressure.
Flexible pneumatic shut-off device: Equipped with a rubber sleeve containing reinforced fabric, it can withstand high-frequency opening and closing operations, resist acids, alkalis, and chemical media, and boasts an extended service life.
Simple Installation: Valves can be installed without orientation; no pipeline cleaning is required. Replacement is quick and easy once the rubber sleeve is damaged.
Ease of Control: Automation operation control can be achieved locally or remotely as required.

Flexible pneumatic flow control device for rainwater and wastewater separation is installed with a liquid flow control gate at the wastewater and rainwater inlets of a traditional interception well, allowing for accurate separation of rainwater and wastewater. The interception well has three pipe openings: an inlet for mixed rainwater, an outlet for wastewater, and an outlet for rainwater. The rainwater pipe connects to the municipal wastewater well, the rainwater pipe to the municipal rainwater well, or discharges to a nearby river. On sunny days, the wastewater gate is open and the rainwater gate is closed, allowing wastewater to flow directly into the wastewater network, while rainwater in the rainwater pipe cannot backflow into the wastewater pipe. During rainy days, the wastewater gate automatically closes and the rainwater gate automatically opens, collecting a large amount of rainwater directly into the rainwater pipe, and wastewater in the wastewater pipe cannot backflow into the rainwater pipe. When the volume decreases or the water level drops, the liquid flow control gate automatically returns to the state where the wastewater gate is open and the two water inlets are closed. The equipment operates fully automatically. By setting the volume and water level values for rainy and sunny days in the program, the device can execute corresponding actions and continuously monitor the on-site conditions.
