The minimum flow valve is widely used in various industries, so its use is certainly very extensive. In fact, this minimum flow valve is used in the hot rolling descaling system of iron and steel enterprises. The medium is water and the working temperature is ≤100℃ on the pipeline; when in use, it mainly protects the normal operation of the pump. The valve can only be fully open or fully closed when in use. If you explain this way, I believe everyone will understand. For these basic knowledge points, at least we will know what it is when we see it. Of course, its advantages are also more. And it's all reflected in different places. Here, with the help of this, we will tell you about the union principle of the minimum flow valve. In fact, when in use, it is generally installed on the branch pipe at the outlet of the water pump, so at this time, when the water pump is running normally, when the outer pipe is supplying water, it is closed. And when the normal operation of the water pump does not supply water to the outside, and does not stop the pump, the product will be controlled by temperature, pressure, and outlet valve chain one of the three ways to open and close.
So the minimum flow valve in use when it is very good to discharge a part of the small flow of high temperature water, to prevent the pump cavitation, to ensure the normal continuous operation of the pump. The minimum flow valve works by high-pressure descaling water (PN25MPa) is temperature controlled, descaling water50℃ Open valve,40C closed. In addition, for users, what we need to know here is that it is mainly used for general water pumps to control the outlet pressure of the pump. Therefore, a pressure switch is installed on the supervisor of the pump outlet. When the pressure exceeds a certain set value (set by the designer according to the site), what we also need to master here is that this minimum flow valve is opened when the pressure is lower than a certain set value, then in this case, the pressure of the normal operation of the pump will fluctuate greatly with the pressure of water supply to the outside world and without water supply, and the design value of the switch will be set by the design institute personnel. Then you can switch it with the main valve to the outside water supply interlock, water supply, the main valve is open, then in this case the opposite is not water supply.
After the introduction of the above content, we have also understood the basic introduction of the minimum flow valve. Other knowledge points will continue to be updated in the next period.
