The water tank according to material is divided into six kinds of glass steel water tank, stainless steel water tank, Stainless Steel Liner and glass steel water tank, water glass steel tank, enamel water tank, galvanized steel water tank. Tank equipped with HYFI remote liquid level electric valve, water level monitoring system and automatic cleaning system and self-cleaning sterilizer, water tank Overflow pipe and a water tank drainage pipe valve connection and insect nets, water tank level should be different two ventilation tube (insect nets), ladder is provided with a water tank inside and outside; tanks (containers) generally have water inlet pipe, a water outlet pipe (living water outlet pipe, a fire outlet pipe), an overflow pipe, drainage pipe, water tank according to the different functions are divided into five kinds of living water tank, fire water tank, production water tank, air tank, household water tower, strict significance on the toilet flushing water tank and water tank of the automobile does not belong to the water tank.

Water tank accessories
(1) the water inlet pipe: the water tank water inlet pipe generally from the side wall access, also can access from the bottom or the top. When the water tank uses the pipe network pressure, the outlet of the water inlet pipe should be provided with a floating ball valve or a hydraulic valve. Floating ball valve generally not less than 2. Float ball valve diameter and the same diameter of the inlet pipe, each float valve should be equipped with the maintenance of the valve before.
(2): water tank outlet pipe can be connected from the side wall or bottom. The water outlet pipe from the water outlet pipe is connected with the side wall of the inner bottom or take out from the bottom of the mouth of the top surface should be higher than the bottom of the water tank 50 mm. The water outlet valve should be set up.
Into the water tank, a water outlet pipe should be respectively arranged, when inlet and outlet pipe with a pipe, a check valve on the outlet pipe are mounted design check. When the need to install check valve, should take the small resistance swing check valve instead of the lift check valve, and the elevation should be lower than the minimum water level of the water tank above 1m. A water tank with the combination of life and fire, fire outlet pipe on the check valves should be less than the life of a water siphon pipe top (below the top of the pipe, vacuum siphon life is destroyed, only to ensure that fire water outlet pipe is provided with a water outflow) at least 2m, to enable them to have a certain amount of pressure to promote check valve. When the fire occurs, the fire water supply can really play a role.
(3) overflow pipe: water tank overflow pipe can be from the side wall or bottom of the pipe, the diameter of the discharge water tank to determine the maximum flow, and should be larger than the inlet pipe l a 2. Valve can not be installed on the overflow pipe. Overflow pipe shall not and the drainage system directly connected, must adopt indirect drainage, overflow pipe should be anti is dust, insects, such as mosquitoes, flies, etc. into the measures, such as setting water seal, a filter screen.
(4): water tank drain pipe drain pipe should be from the bottom of the lowest. Vent pipe Figure 2 - 2n fire and life table with a water tank installed with a Gate Valve (not to be installed to allow the valve), can be connected with the overflow pipe, but not directly connected with the drainage system. The diameter of the water discharge pipe is usually adopted by DN50 in the absence of special requirements.
(5) the ventilation pipe: the water tank for drinking water should be provided with a sealing box cover. Ventilation tube can be extended to indoor or outdoor, but shall not be extended to the harmful gas, nozzle should prevent dust, insects and flies entering the filter should generally be toward the nozzle set. Ventilation pipe device shall be installed in the valve seal, obstruct ventilation. The ventilation pipe may not be connected to the drainage system and the ventilation duct. Ventilation tubes generally use DN50 diameter.
(6) level gauge: generally, the glass level gauge should be installed on the side wall of the water tank, which is used to indicate the water level in situ. When the liquid level meter is not enough, 2 or more liquid level meters can be installed up and down. 2 adjacent level of the overlapping parts, not less than 70 mm, see Figure 2 - 22. If the liquid level signal is not installed in the water tank, the signal can be set to give the signal of overflow. Signal pipe generally from the side wall of the water tank connected, the installation height should be the bottom inner tube and overflow tube bottom or bell mouth overflow water level together. The pipe diameter is generally used DNl5 signal tube can be connected to the wash basin, washing basin and other places in the room. If the water tank level and pump chain, in the water tank side wall or the top of the installation of liquid level relay or signal device, commonly used in liquid level relay or signal device with floating ball type, rod type, capacitance and floating flat type, etc..
Water pump pressure water tank level of telegraphic address water level should be considered maintain certain safety volume, stop pump instantaneous maximum control level should be below the overflow water to 100 mm, and instantaneous pump minimum control water level should be higher than the design to the lowest level of 20mm, lest because of error caused by overflow or venting.
