What is the constant flow regulating valve? It is a equipment for what? What is it works? Then the following OLS valve to tell you.
Because of the circulating water pipe network system of central heating or central air-conditioning, the widespread hydraulic imbalance, because the association between resistance and various loop coupling between the different, resulting in uneven flow of the transmission and distribution, control difficulties, thus system operation caused by poor quality, unstable flow control is not accurate, the user terminal uneven, forced to use large flow operation, many problems such as the serious waste of energy. The main reason is the use of poor quality are not reliable, easy to use, low cost of traffic control devices. However, constant flow control valve is a special control device designed to overcome these problems and research, it can carry out accurate and reliable flow control and distribution, the eradication of hydraulic maladjustment. Circulating water pipe network of central heating or central air-conditioning, constant flow pneumatic control each valve installed in the loop end, according to the rated flow of each user's setting opening, can realize the balance of the whole network system of transmission and distribution, ensure the system lose balance and steady flow, improve operation quality, implement energy-saving operation. No special debugging techniques and instrumentation, adjusting the setting simple and intuitive, fast and reliable. Water in a central heating or central air conditioning in the building automation system, the constant flow control valve flow control system can guarantee the stable, accurate and reliable with freely valve actuator, improve operation quality, reduce the valve actuator action times and prolong its service life.
According to the related data, in the central heating system in the flow distribution, reasonable and balanced, realization of hydraulic balance, energy saving, coal saving the above 15-20%, equivalent to every heating season per square meter construction area to reduce operating costs 0.5 yuan or more; solve the problem of the heating pipe network flow distribution is not balanced, so that the end user at room temperature standard term is not hot, not only can reduce customer complaints, also can improve the rate of charge, at the same time, pneumatic diaphragm seat regulating valve can also give full play to existing capacity pump boiler, expand the heating area, economic benefits and social benefits are very considerable. Constant flow control valve is a valve with constant flow function, it is the self-operated differential pressure control device and flow control device combination valve, its working principle is: the control device for the pressure difference, to control and stabilize the flow regulation device before and after the pressure, so that the valve after the pressure difference before and after the is greater than the current start value, the flow is no longer with the valve before and after the pressure changes, the pressure difference control range, through an opening valve can automatically maintain a constant flow, flow rate changes only need to adjust the valve opening can be realized, has nothing to do with the before and after the valve pressure difference.
