Information

  The regulating valve of the pneumatic flow valve is a control device that can realize constant flow intuitively and easily, and the specific value can be adjusted. It is also called a constant flow control valve or a controller or a balance valve. The pipeline network application can be set according to the design value, and no external force is required after the setting. No matter how the residual pressure head and pressure fluctuations at the pipeline end fluctuate, the flux value set by the pipeline can be maintained under the action of the pressure difference before and after the valve. Change, simplify the complex network adjustment work in the original official website to the default value setting.

The small flux control valve of the pneumatic flow valve, as the name implies, is a type of adjustable flow valve that the weight of the medium passing through per unit time is not large and can be adjusted within a certain range. The flow capacity is defined as when the valve is fully opened, when the pressure difference between the front and rear of the valve is 1 kg/cm, and the specific gravity of the medium is 1 g/cm, the weight of the medium passing through unit time (m3/hour).

The flow capacity of the small flux regulating valve of the pneumatic flow valve is closely related to the medium or flow conditions. Once these external conditions change, the flow state of the liquid in the valve body will change greatly. In the case of small flow, especially when the viscosity of the fluid is high and the pressure is low, the flow of the fluid tends to be laminar, or a mixture of laminar and turbulent. When flowing in a laminar flow state, there is a linear relationship between the medium throughput of the fluid and the pressure difference before and after the valve body. When the flow velocity increases and begins to transition to a laminar, turbulent mixed flow regime, the amount of medium flowing through will increase with the increase of the Reynolds number even if the pressure difference remains unchanged. Pneumatic flow valve

As the flow capacity of the small flux regulating valve of the pneumatic flow valve decreases, the adjustable ratio of the valve will decrease. But at least it can guarantee between 10:1 and 15:1. If the adjustable ratio is smaller, it will be difficult to adjust. So the main question is how to carry out proper control. From the point of view of economic effect, users hope that a valve can be used for interception and adjustment at the same time, and it can be done now.

This type of valve has the advantages of explosion-proof and reliable performance. The maximum operating pressure can reach 100 kg/cm, and the rated flow capacity can range from 0.05 to 0.0012. This kind of valve is often used in occasions where accuracy is not very high, but the reproducibility of volume accuracy and characteristics is poor. Pneumatic flow valve

This type of valve is mainly used in: central heating (cold) and other water systems, so that the pipe network can be distributed on demand, eliminate the hydraulic imbalance of the water system, automatically eliminate the pressure difference fluctuation, and completely solve the large pressure difference at the near end and the pressure difference at the far end. small contradiction. Reduce the amount of circulating water in the system and reduce the resistance, which can save energy and electricity by 15%-20%. It can be set according to the design or actual requirements, without the need for cumbersome hydraulic balance calculation for the pipe network, simplifying the complex network adjustment work into a simple total allocation. Completely overcome the phenomenon of uneven heating and cooling, and improve the quality of heating and cooling. Eliminates the need for multiple heat sources and the redistribution of the throughput when the pipe network heat sources are switched.
