1、 Drainage cap specifications:
250kg-DN15； 500kg-DN23, DN25； 1000kg-DN32
2、 Characteristics of drainage cap:
The drainage cap has high mechanical strength, a large gap area, and good stability in pure water.
3、 Usage of drainage cap:
Various specifications of filter caps are suitable for various matching ion exchange columns, activated carbon filters, and can also be used in the drainage system of fast filter tanks. The filter head is the steam water backwashing device of the bottom water distribution system of the filter tank, which can effectively flush out sludge and debris in the filter tank, ensuring the normal operation of the water quality and quantity of the filter tank; The types of filter heads include mushroom shaped, plum blossom shaped, tower shaped, and cylindrical shaped, all made of ABS engineering plastic. The structure is reasonable, the connection is firm, the pressure strength is high, the gap is not deformed, and there is no dead water corner area between the filter plates, no mud accumulation, and good effect. The hourly drainage capacity is 0.25 tons, 0.5 tons, and 1 ton. Long stem filter heads are commonly used in the backwash water distribution system of filter tanks; Short stem filter heads are used in filtration devices for water treatment equipment such as single water backwashing, gravity type, pressure type filter tanks, and ion exchange filter beds. The filter head and cap are used for advanced purification of urban drinking water and industrial water. The filter head and cap are advanced purification materials used in the production of high-purity water and mineral water. The filter head and cap effectively remove COD, pigments, and toxic substances from water.
