Product Description

Product Introduction: D-050 High and low inlet combined exhaust valve/high and low inlet and exhaust valve/combined exhaust valve/low pressure high speed inlet and exhaust valve/combined air valve/high and low inlet combined stainless steel exhaust valve by high pressure micro exhaust valve and low pressure inlet and exhaust valve two parts of the combination of exhaust and intake functions. High pressure micro automatic exhaust valve in the pipeline pressure state automatically discharge the internal accumulation of a small amount of air. Low pressure intake and exhaust valve can not only discharge the air in the pipeline when the empty pipeline is filled with water, but also automatically open the air intake into the pipeline to eliminate the negative pressure when the pipeline is emptied or negative pressure occurs, such as water column separation conditions.

Working principle: The large inlet and outlet of D-050 high and low inlet and outlet valve assembly ensures that the air enters and exits the high-speed discharge air stream with a higher flow rate, and even the high-speed air stream mixed with water mist will not close the exhaust port in advance and cause the gas seal. The exhaust port is only closed after the air has been completely discharged. Any time the system is low to atmospheric pressure, such as when the water column separation phenomenon occurs, the air valve will immediately open into the system to intake air, to prevent the vacuum in the system. At the same time, timely air intake can speed up the emptying speed when the system is emptying. The exhaust process is smooth and can prevent pressure fluctuations or other destructive phenomena.
The large inlet and outlet of the low-pressure inlet and outlet assembly allows the air to enter and exit the high-speed discharge air stream at a higher flow rate, and even the high-speed air stream mixed with water mist will not seal the exhaust port in advance and cause the gas seal. The exhaust port is only closed after the air has been discharged. Any time the system is low to atmospheric pressure, such as when the water column separation phenomenon occurs, the air valve will immediately open to the system to intake air, to prevent the vacuum in the system. At the same time, timely air intake can speed up the emptying speed when the system is emptying. The exhaust process is smooth and can prevent pressure fluctuations or other destructive phenomena. The high-pressure micro-exhaust valve can discharge the air accumulated at high points in the system in time when the system is under pressure to avoid the following phenomena that may cause harm to the system: air blockage or gas blocking: Increasing the head loss of the system reduces the flow rate or even in the case of fluid delivery can lead to complete interruption. Aggravating cavitation damage accelerates the corrosion of metal components, aggravates pressure fluctuations in the system, and increases the error of metering equipment gas explosion
1. The air in the discharge pipe makes the water filling proceed smoothly. 2. After the air in the pipeline is emptied, the water enters the low-pressure inlet and exhaust valve/exhaust valve and the float ball is lifted by the buoyancy to seal the inlet and exhaust port. 3, the air released from the water during the water transmission process will be collected in the high point of the system, that is, the air valve to replace the original water in the valve body. 4. With the accumulation of air, the liquid level in the high-pressure micro-automatic exhaust valve drops, and the float drops accordingly, pulling the sealing coil chain, opening the exhaust port, and releasing air. 5. After the air is discharged, the water enters the high pressure micro automatic exhaust valve again, floats the floating ball and seals the exhaust port. In the case of system operation, the above 3, 4, 5 steps will continue to cycle when the pressure in the system of low atmospheric pressure (negative pressure) when the combined air valve working process: 1, the float ball of the low pressure inlet and exhaust valve/exhaust valve will immediately fall to open the inlet and exhaust port. 2, the air thus into the system, eliminate negative pressure, protect the system. D-050 High and low entry stainless steel flange exhaust valve Tenglong air butterfly valve exhaust valve product features: smooth operation, avoid causing water hammer. The structure designed according to the principle of fluid mechanics can prevent the occurrence of gas sealing phenomenon (that is, when the air in the system has not been completely discharged, the float is blown by the high-speed air flow and the exhaust port is closed) small size, light weight, simple structure and high reliability. Specially designed exhaust seal structure: by bronze seat ring and flexible EPDM rubber combination of long-term maintenance free operation. The exhaust port can be connected to the external exhaust pipe high pressure trace automatic exhaust valve: A-RI technology: chain seal super large exhaust port: can prevent the exhaust port from being blocked by impurities High exhaust volume: about 14 times of the traditional exhaust valve automatic exhaust within the full working pressure range (up to 25Kg) body adopts high strength materials All internal parts are made of anti-corrosion materials Optional Model: D-050: working pressure range 0, 2 -- 16kg high pressure trace automatic exhaust valve body material is nylon D-050-C: working pressure range 0, 2 -- I6kg high pressure trace automatic exhaust valve body material is cast iron D-052: Working pressure range 0, 2 -- 25kg high pressure trace automatic exhaust valve body material is cast iron D-052-V: unidirectional intake/exhaust type.
