The pressure tank and expansion water tank are a new type of building water supply and drainage equipment. The equipment has a reasonable structure and advanced technology, and can be used as both building water supply and fire water supply equipment, as well as a constant pressure equipment for hot water heating and air conditioning systems.

1、 Model Description of Pressure Tank and Expansion Tank

2、 Scope of application
1. Suitable for water supply and fire water supply systems in urban residential areas, multi story and high-rise buildings.
2. Suitable for boiler rooms, thermal stations, and various high and low temperature hot water heating systems, it plays a role in replenishing water and maintaining pressure.
3. Suitable for industrial water supply. Rural water supply and sprinkler irrigation water supply system.
4. Suitable for situations where the pressure in the water supply network is unstable, it can eliminate water hammer and water flow noise
5. Suitable for dry fire tower pressure stabilization system
6. Suitable for transporting other liquids with physical and chemical properties similar to clear samples.
3、 Product Features
1. Structural characteristics
1) The diaphragm structure inside the tank ensures that water does not come into contact with the tank wall, so there is no rust inside the tank wall. There is no external condensation phenomenon, and the service life of the equipment casing is greatly extended.
2) Closed operation and gas water separation can effectively avoid secondary pollution.
3) The full membrane structure ensures that the capsule is fully adhered to the inner wall of the tank, reducing its passive pressure condition, extending the service life of the capsule, and ensuring reliable operation.
2. Functional Features
1) It can automatically eliminate water hammer and noise in the pipeline network, effectively protecting water pumps, pipeline accessories, and heat dissipation equipment.
2) Ensure stable system operation, constant pressure to save energy, and effectively prevent vacuum and water shortage phenomena.
3) Replacing open high-level water tanks, water towers, and open expansion water tanks on building roofs, it is directly installed in underground or above ground equipment rooms, reducing project costs, making construction and installation simple, and beneficial for structural seismic resistance.
3. Environmental characteristics
1) Built in pure natural rubber synthetic capsules.
2) The equipment shell is coated with environmentally friendly and zero pollution water-based paint, which does not contain harmful solvents such as benzene, toluene, formaldehyde, etc., and is harmless to the human body
