When laying and installing water and gas supply systems, various types of fittings are used that have a specific purpose. One of its important elements is balancing valves (or valves).
Balancing valves and their modifications
The balancing valve (or valve) belongs to the class of pipe fittings, the main function of which is to regulate excessive pressure in heating
systems, ventilation systems, plumbing and cold-conducting. Valves are used for hydraulic linkages of throttle rings and rings for circulating liquids or gas-air masses.
These valves are divided into manual, automatic and combined type.
The manual balancing valve (for the aquatic environment) is commonly used in those systems where static hydraulics are installed. Automatic valves are designed for systems operating on dynamic hydraulics. In such systems, balancing is necessary due to possible pressure drops and the need for its regulation.
Improper water circulation in heating systems is fraught with many unpleasant consequences. If in the radiators and the boiler there is a small pressure and lack of water, firstly, the room will have a low temperature, and secondly, this will lead to corrosion of the boiler itself. And at too high temperatures (if the balancing valve is absent in the system), extraneous noise appears in the batteries and pipes. Therefore, valves are always installed on collectors and risers. Heat points are not complete without them.
For connection with other parts of the valve, the balancing valve is provided with an internal or external thread. The maximum temperature mode of operation is up to 120 degrees above 0, and up to 20 degrees below 0 (on the Celsius scale). The valves are equipped with drainage devices, pressure measurement indicators and settings locks.
Valves from Danfoss
The market for sanitary fittings presents the widest selection of different parts and elements. One of the most popular manufacturing companies is the Danish company Danfoss. It produces a balancing valve of such a popular brand as "MSV-BD".
The manufactured products belong to the latest type of balancing valves, which are involved not only in heating and cooling systems, but also in hot water supply systems. They organically combine the properties and capabilities of both a valve and a ball valve.
The balancing valve Danfoss has a number of advantages compared to similar products:
- simplicity of all kinds of settings;
- convenient location of the indicator scale, allowing you to see the setting from any angle ;
- two measuring nipples;
- additional drain valve, allowing bilateral drainage;
- open and close the valve in unforeseen situations with the help of a hex key;
- there is an indicator on the handle indicating the position of the valve in the open / closed system.
To adjust the correct operation of the balancing valve, a portable water flow meter is designed. This can also be done based on water temperature or on hydraulic calculations.
