Analysis on the Selection of Flow Control Valve

Flow control valve, in the measurement of heating systems, occupy a very important position. Therefore, how to correctly select the flow control valve and design, it is particularly crucial! This article starts with the structure and working principle of the flow control valve, and puts forward the problems that should be paid attention to in the selection and design of the control valve. Thermostatic valve in the selection of the design, with the selection of the same diameter pipe temperature control valve, but also to the selected temperature control valve to create an ideal working conditions of pressure; electric control valve is suitable for computer monitoring System for flow control equipment, generally more unattended in the thermal station to use; For manual balance method, how to use the valve characteristic curve analysis of the valve regulating performance, how to solve the valve in the case of small opening valve easy Leading to the phenomenon of the impact of steam hit; self-flow control valve in the design and selection of the valve to note the minimum work poor requirements. Thermostatic valve Electric control valve Balance valve Differential pressure control valve Heating system The implementation of heat metering charges can save energy and improve energy efficiency of the heating system. As far as the current situation is concerned, the energy efficiency of our heating system is only about 30%. People often only pay attention to the boiler and the heat loss of the network, while ignoring the heat user heat loss. Thermal user heat loss, mainly due to uneven heat caused by this part of the heat loss of about 30 ~ 40%, is quite impressive. Heat metering system to engage in charging, from the energy point of view, mainly to tap this part of the potential for energy saving. Metering charges mainly through three ways of macro-energy: First, the installation of the flow control valve, to achieve the flow balance, thereby overcoming the uneven heating and cooling; followed by the role of temperature control valve, the use of solar energy, appliances, lighting, etc. Equipment, free heat; the third is to raise the awareness of energy saving with residents, reducing unnecessary windows and other heat. The three energy-saving ways, of which two are through the flow control valve to achieve. Can be seen, flow control valve, heating system in the measurement of charges, what occupies an important position. Therefore, how to correctly select the design of flow control valve, it is very important. First, the temperature control valve 1, the radiator thermostatic valve structure and working principle The user's indoor temperature control is achieved through the radiator thermostatic control valve. Radiator thermostatic control valve is a thermostat controller, flow control valve and a pair of connectors, of which the thermostat is the core component of the sensor unit, that temperature package. Temperature package can sense changes in the ambient temperature and volume changes, drive the valve spool displacement, and then adjust the radiator water to change the radiator heat dissipation. Thermostatic valve set temperature can be artificially adjusted, thermostatic valve will be set according to the requirements of automatic control and adjust the radiator water, in order to achieve the purpose of controlling the indoor temperature. Temperature control valve is generally installed in front of the radiator, through the automatic regulation of flow, to achieve the residents need room temperature. There are two thermostatic valve thermostatic valve and thermostatic valve three points. The three-way thermostatic valve is mainly used for single-pipe system with crossing pipe. The shunt coefficient can vary from 0% to 100%, and the flow control has a large space but the price is more expensive. The structure is complicated. Two-way thermostatic valve for some double-tube system, and some for single-tube system. The two-way thermostatic valve used in the two-pipe system has greater resistance; the one-pipe system used has less resistance. Thermostatic valve temperature sensor package and the valve body is generally assembled into a whole, the temperature package itself is the scene of the indoor temperature sensor. If desired, a remote temperature sensor can be used; the remote temperature sensor is placed in a room requiring temperature control and the valve body is placed in a location on the heating system.
