Diaphragm type pressure tank (diaphragm expansion tank)
Product overview
Diaphragm type pressure tank can replace the high expansion tank widely used in hot water supply, hot water heating, district heating and air conditioning system, in order to achieve automatic replenishment and constant pressure. The utility model can be used as a water supply device for supplying water for life, production or fire fighting.
Two, working principle
The pressure tank is a prerequisite for the pump can go into sleep, the properties of water compressibility is small, with a force storing water tank, compresses the gas pressure increases, when the external force disappears expansion of compressed gas can be out of the water. Because the water compression ratio is much smaller than the gas, when the pipe network with small flow leakage can cause a significant drop in pressure, the pump can start frequently. If the power pump directly to the user water supply, it must be equipped with a pressure tank, ease the problem of frequent start pump. Standard welding technology, with air supply and discharge device.. The surface is coated with advanced spraying technology and has good corrosion resistance.
Three, the main features
1, the tank for the sealing device, gas water contact, to ensure that water quality is not subject to external pollution.
2, a gas can be used to ensure long-term use, the user does not need to set up an inflatable device.
3, can be divided into food grade natural rubber, not more than 200 thousand times, can be used in the water system. 4, equipment covers an area of small, investment saving, fast installation, easy to centralized management and maintenance.
5, can automatically eliminate the water hammer and noise. 6, can replace the live fire and heating, air conditioning with a high water tank and a water tower, is conducive to building the appearance and structure, reduce the cost of building. 7, in the hot water heating and air conditioning system from the expansion of the role of the tank and the role of automatic replenishment
