Agricultural irrigation accessories- “EV inlet exhaust air valve” to relieve the pressure of irrigation equipment

The exhaust valve, also known as air intake valve, exhaust valve, air valve, hereinafter referred to as the exhaust valve.

In the agricultural water -saving intelligent irrigation system, various water conditioning irrigation pipes need to install an additional exhaust valve. The exhaust valve can ensure that the air pressure in the pipeline is in normal state and will not cause high pressure or negative pressure. The stable work of the device.

Since the exhaust valve is so important for agricultural irrigation, then we will study what the exhaust air valve is, and what are its characteristics and use?

What is “EV inlet exhaust air valve”

The EV inlet exhaust air valve is a combined air valve that can be suitable for various irrigation systems to help the irrigation system maintain a normal pressure state and maintain the stable work of the irrigation system.

The exhaust valve should have two functions: air intake and exhaust. When water injection of the system, the valve discharge a large amount of air in the pipeline; in the normal working state of the system, the valve can discharge a small amount of air in the pipeline; when the system is emptied, the air enters the system through the valve to destroy the inner vacuum of the pipe to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to control the pipeline to prevent the pipeline in order Be “sucking”.

This air valve is designed with advanced composite gas dynamics, which has a fast exhaust function, which can avoid the formation of air accumulation and vacuum negative pressure. It has good sealing performance during low pressure.

The characteristics of “EV inlet exhaust air valve”

1. The valve body adopts DC to the design. The size of the exhaust port is large and the flow is large.

2. The long -sealing floating ball moves the schedule, which can prevent the floating ball from being blown up by high -speed air flow and cause the exhaust port to close prematurely, and does not affect air inhalation or exclusion.

3. Low -pressure sealing can be kept well at low pressure (0.2BAR) to avoid leakage

4. All components have corrosion resistance and low maintenance frequency, so the service life is relatively long.

Application in irrigation system:

In the irrigation system, the exhaust valve is generally installed at the “hump” of the pipeline, the end of the pipeline, the total irrigation head, and the first part of the field.

Long -distance equal diameter pipelines, long -distance horizontal pipelines, and long -distance sloping pipelines should be installed every hundred meters every hundred meters. Press.

The cost of the exhaust valve is low and there are many classifications, such as vacuum destruction valves, fast exhaust valves/absorbing exhaust valves, automatic exhaust valves, combined exhaust valves, etc., which can be used to effectively protect the drip irrigation valve. The system also guarantees the irrigation efficiency and effect of crops.
