Product Description
1. Product Overview
The HA009-4X-10/16Q Compound High-Speed Inlet and Exhaust Valve, affectionately known as the 'exhaust valve,' is an ingenious control device tailor-made for water supply pipelines. Celebrated for its versatility, this valve shines across diverse water supply network systems. What sets this marvel apart is its 'compound' nature-enabling a single chamber to masterfully handle both large and small orifices for seamless inlet and exhaust functions.
Key Features:
1)The valve's simplicity is its genius-designed with automatic inlet and exhaust capabilities for both large and small orifices, it stands as a beacon of reliability and ease, requiring virtually no maintenance.
2)Unleashing a powerful exhaust capacity, this valve reaches an impressive exhaust speed of up to one Mach, equivalent to 340 m/s under normal atmospheric pressure, ensuring rapid and efficient operation.
3)Engineered to perfection, the exhaust pressure differential (air closure pressure) exceeds 0.2 MPa, ensuring the exhaust remains steadfastly open, defying self-closure under any pressure differential.
4)In the routine flow of water transmission, the small exhaust orifice diligently vents any pressure airbags that might gather within the pipeline, significantly boosting the efficiency of high-altitude water conveyance.
5)Once the air within the pipeline has been expelled, this valve's remarkable design allows it to snap shut instantly upon encountering pressurized water, ensuring no leakage and maintaining seamless operations.

3.Operating Principle
Positioned with precision, the exhaust valve graces the apex of the longitudinal pipeline axis, ensuring efficient air management. As air infiltrates the pipe, it instinctively gravitates towards the exhaust valve, setting the stage for optimal performance.
1)During the critical phase of water infusion into an unfilled pipeline: Air trapped within is effortlessly managed as the float and lifting hood succumb solely to gravity, lacking any buoyancy. This causes them to rest at the base of the float hood. As water pressure builds, air is swiftly expelled into the atmosphere through strategic openings, ensuring a seamless transition.
2)Witness the marvel of self-sealing efficiency: Post air expulsion, water gracefully ascends into the valve chamber, prompting the float and lifting hood to ascend, effectively sealing the valve hole. The exhaust valve effortlessly transitions to a closed state, ensuring no water leakage-a testament to its flawless design.
3)Experience ongoing operational excellence with the small hole exhaust mechanism: Pressure variations in the pipeline facilitate the gradual release of dissolved air, which congregates at the pinnacle of the valve chamber. An evolving airbag forms, prompting a drop in the water level. When buoyancy dwindles, the float descends, activating the small exhaust port for automatic air release. As gas is expelled, equilibrium is restored, and the cycle of intermittent small hole exhaust perpetuates.
4)Automatic air intake ensures safety by dispelling vacuums: Should a vacuum arise within the pipeline, the float and lifting hood swiftly descend, permitting a flood of air to enter. This vital function dismantles the vacuum, safeguarding the integrity of the pipeline network.
4.Key Performance Features
1)Revel in the simplicity of design coupled with dual functionality: This ingeniously crafted structure caters to both large and small orifice inlet and exhaust operations (see Figure 1). Delight in its reliable performance and enjoy the luxury of a product that is virtually maintenance-free.
2)Marvel at the unmatched exhaust capacity, achieving breathtaking speeds of up to Mach 1, ensuring swift and efficient operation.
3)With an outstanding exhaust pressure difference surpassing 0.2MPa, this system remains open under any pressure variance, eclipsing both domestic and international counterparts.
4)The marvel lies in the automatic discharge of gas from the pressure bag, maintaining peak performance during standard operations.
5)Rapid response post-gas expulsion: The valve promptly closes upon encountering water, exemplifying its exceptional responsiveness.
