CARX compound quick exhaust valve is a high-performance automatic valve integrating high-speed mass exhaust, continuous trace exhaust and quick air admission functions. The composite air valve is based on the principle of buoyancy effect of water on stainless steel float ball. When the water level of the exhaust valve rises, the float ball will automatically float under the buoyancy effect of water until the valve clack contacts the sealing surface of the valve seat seal ring at the exhaust port. When the buoyancy increases to more than the required specific pressure of the sealing surface, the exhaust port will be automatically closed. The valve is optimized for the gas management requirements of the pipeline system in different stages such as water filling, operation and emptying. The composite double-port structure is adopted, which can realize the combination of rapid gas throughput and precise control, effectively prevent the hazards of pipeline air resistance, water hammer and negative pressure, and ensure the safe, efficient and stable operation of the system under various working conditions. Widely used in municipal water supply network, large building water supply system, HVAC circulating system, industrial cooling water system, fire pump room and long-distance water transmission project pipeline highest point or key node. It is especially applicable to the occasions with frequent start and stop of the system, easy to produce water hammer or negative pressure, and high exhaust efficiency requirements. It is one of the core equipment to ensure the smooth and safe operation of the fluid transmission system.

feature

1. Trinity water hammer protection

The valve integrates high-speed intake/exhaust valves and micro exhaust valves. The high-speed valve is responsible for quickly introducing air to prevent vacuum when the pipeline is emptied, and for instantaneous high-speed exhaust to buffer pressure peaks when the water column backflow is bridged; The micro valve continuously discharges dissolved gases, achieving comprehensive protection throughout the entire process and at multiple levels.

2. Millisecond level rapid response

The moving parts are designed with lightweight and minimal inertia, ensuring rapid opening and closing in milliseconds when there is a sudden change in pipeline pressure, and immediately inhaling or discharging air, effectively suppressing the generation and propagation of pressure waves.

3. Large circulation capacity and high-pressure design

The intake and exhaust ports have been optimized to have a large air throughput capacity, which can instantly balance pipeline pressure. The valve body is made of high-strength materials (such as cast steel, stainless steel), and the key parts are reinforced to withstand high system working pressure and water hammer impact.

4. High reliability and tight sealing

In response to the severe impact of water hammer conditions, the internal mechanism is designed to be sturdy and durable. In non operating state, the sealing pair can ensure tight closure, prevent medium leakage, and ensure that the valve remains reliable even after long-term standby or frequent operation.

5. Maintain friendliness and wide applicability

Adopting flange connection, the upper cover is often designed to be detachable for easy internal inspection and maintenance. Suitable for various liquid media such as clean water, raw water, and circulating cooling water, it is a standard protective configuration for high-risk nodes such as pump stations, long-distance pipelines, and industrial process systems.
