Now there are a lot of people for the minimum flow valve some of the basic information is not understood, so as manufacturers, we are also necessary to briefly explain, in fact, the minimum flow valve is also called boiler feed pump recirculation valve. In the power plant, it is installed at the outlet of the feedwater pump and connected to the deaerator. Although its name is still different. But in the future, when you see it, you should at least know that it is the same device. When it is in use, of course, the boiler feed pump sucks water out of the deaerator and sends it to the boiler. Then, at this time, in order to prevent the feed pump from overheating and cavitation, the flow rate of the feed pump must not be less than a specified safe flow rate, that is, the minimum flow rate, under any circumstances. In the future, when everyone sees it, at leastKnow where it is used. Here is a regular manufacturer, want to order the product friends may wish to come here to choose it. Believe that will not let you down. The price here is reasonable and the quality is guaranteed. Moreover, there are many types of products, and there is always one suitable for you. Welcome to buy.
When the minimum flow valve is used, when the boiler feed water needs a very small flow rate, such as when the turbine trips, then the minimum flow valve should be opened in time at this time, and then a part of the high-pressure water should be returned to the deaerator from the pump outlet to ensure the safe operation of the feed water pump. The system in which the valve is located is called a recirculation system. The main function of the minimum flow valve is to prevent the pump flow from being too small,Boiler feed pump cavitation; here played a very important role. Of course, if there is not enough flow in the pump when the boiler feed water pump is started, the working fluid in the feed water pump will vaporize and damage the pump. It is suggested that you can turn on the recirculation at this time to ensure that there is enough water in the pump. In addition, the minimum flow valve introduced today is set to prevent vaporization of the feed water pump, and the fixed value is generally provided by the manufacturer, therefore, when it is working, when the inlet flow rate of the feed pump is lower than the minimum value, its valve opens. If the flow rate is lower than the jump pump after opening, it protects the feed pump. Welcome to consult relevant information.
The content of the above article is some relevant information about the role and working principle of the minimum flow valve introduced by the editor. If you didn't know before, you can come and have a look now. The next issue will also tell you about the knowledge points related to it. Remember to watch.
