Flange double ball composite exhaust valve

DN50-200
Product OverviewCARX dual ball composite exhaust valve (dual port exhaust valve) adopts a large and small dual floating ball composite structure, with a valve body cast of ductile iron and a deep blue anti-corrosion coating sprayed with epoxy on the inside and outside. Integrating three major functions: large caliber rapid exhaust, micro exhaust, and negative pressure air supply: during the water filling stage of the pipeline, the large ball quickly discharges a large amount of air; During normal pressurized operation, the small ball continuously releases trace gases that dissolve and precipitate; When the pump stops and negative pressure is generated due to pressure relief, it automatically enters the air to avoid pipeline collapse and water hammer damage. It is a standard valve for high points of municipal water supply and long-distance water transmission main pipelines, and can be matched with the check valve and Y-shaped filter in the pump room.Core technical parameters• Model: CARX-16Q• Nominal diameter: DN50~DN250• Nominal pressure: PN10/PN16 (optional PN25)Valve body material: QT450-10 ductile ironAnti corrosion coating: Internal and external epoxy resin electrostatic spraying, meeting drinking water standardsFloating ball component: 304 stainless steel large floating ball+small floating ballSealing element: NBR nitrile rubberFlange standard: GB/T9113Applicable media: tap water, fire-fighting clean water, circulating cooling water• Medium temperature: 0-80 ℃Installation method: Vertically installed at the highest point of the pipeline, with the valve opening facing upwards• Inspection standard: GB/T13927Product advantages1. Dual ball composite, covering all working conditions. The large ball is responsible for the rapid exhaust of high flow during the initial water flow, quickly eliminating air blockages; The ball is responsible for continuous micro exhaust under normal pressure conditions to solve the problem of continuous bubble precipitation; Automatic suction under negative pressure, one valve can accommodate three working conditions, replacing the combination of single port and micro exhaust valve, saving installation costs.2. It is resistant to water hammer and is not easily shut off. The double floating ball independent guiding structure will not be blown off by the airflow in advance under high-speed airflow, avoiding "self sealing" failure. The stability of water hammer working conditions for long-distance pipeline start stop pumps is much better than that of ordinary single port exhaust valves.3. Epoxy full coating anti-corrosion, water quality safety, strong adhesion of epoxy coating on the inner and outer walls, resistance to damp underground valve well environment, not easy to rust, and not polluting clean water medium.4. The sealing is reliable, and the pressure bearing floating ball guide limit design does not drip water. The floating ball does not sway under water flow disturbance, and the sealing surface fits stably. The risk of leakage during long-term pressurized operation is low.5. Easy to maintain, the top valve cover bolts are detachable, allowing for easy inspection and cleaning of internal sediment and impurities without the need for complete valve disassembly.6. Reduce air resistance, improve water delivery efficiency, continuously discharge accumulated air in the pipeline, eliminate air pockets, stabilize pipeline flow, reduce water pump energy consumption, and reduce pipeline vibration and abnormal noise.Application ScenariosMunicipal tap water main pipeline network, long-distance water transmission pipeline, secondary water supply pump room, fire main pipeline, water plant water transmission pipeline, irrigation main pipeline high point.

  • Product Overview

    CARX dual ball composite exhaust valve (dual port exhaust valve) adopts a large and small dual floating ball composite structure, with a valve body cast of ductile iron and a deep blue anti-corrosion coating sprayed with epoxy on the inside and outside. Integrating three major functions: large caliber rapid exhaust, micro exhaust, and negative pressure air supply: during the water filling stage of the pipeline, the large ball quickly discharges a large amount of air; During normal pressurized operation, the small ball continuously releases trace gases that dissolve and precipitate; When the pump stops and negative pressure is generated due to pressure relief, it automatically enters the air to avoid pipeline collapse and water hammer damage. It is a standard valve for high points of municipal water supply and long-distance water transmission main pipelines, and can be matched with the check valve and Y-shaped filter in the pump room.

    Core technical parameters

    Anti corrosion coating: Internal and external epoxy resin electrostatic spraying, meeting drinking water standards

    Floating ball component: 304 stainless steel large floating ball+small floating ball

    Sealing element: NBR nitrile rubber

    Flange standard: GB/T9113

    Applicable media: tap water, fire-fighting clean water, circulating cooling water

    • Medium temperature: 0-80 ℃

    Installation method: Vertically installed at the highest point of the pipeline, with the valve opening facing upwards

    • Inspection standard: GB/T13927

    Product advantages

    1. Dual ball composite, covering all working conditions. The large ball is responsible for the rapid exhaust of high flow during the initial water flow, quickly eliminating air blockages; The ball is responsible for continuous micro exhaust under normal pressure conditions to solve the problem of continuous bubble precipitation; Automatic suction under negative pressure, one valve can accommodate three working conditions, replacing the combination of single port and micro exhaust valve, saving installation costs.

    2. It is resistant to water hammer and is not easily shut off. The double floating ball independent guiding structure will not be blown off by the airflow in advance under high-speed airflow, avoiding "self sealing" failure. The stability of water hammer working conditions for long-distance pipeline start stop pumps is much better than that of ordinary single port exhaust valves.

    3. Epoxy full coating anti-corrosion, water quality safety, strong adhesion of epoxy coating on the inner and outer walls, resistance to damp underground valve well environment, not easy to rust, and not polluting clean water medium.

    4. The sealing is reliable, and the pressure bearing floating ball guide limit design does not drip water. The floating ball does not sway under water flow disturbance, and the sealing surface fits stably. The risk of leakage during long-term pressurized operation is low.

    5. Easy to maintain, the top valve cover bolts are detachable, allowing for easy inspection and cleaning of internal sediment and impurities without the need for complete valve disassembly.

    6. Reduce air resistance, improve water delivery efficiency, continuously discharge accumulated air in the pipeline, eliminate air pockets, stabilize pipeline flow, reduce water pump energy consumption, and reduce pipeline vibration and abnormal noise.

    Application Scenarios

    Municipal tap water main pipeline network, long-distance water transmission pipeline, secondary water supply pump room, fire main pipeline, water plant water transmission pipeline, irrigation main pipeline high point.
