The long-handled filter head manufactured by Sanfan Water Treatment is made of brand-new
, B
engineering plastic material, which has high pressure-bearing capacity and impact resistance. It has the remarkable effect of strong ability, strong tensile strength and resistance to breakage and cracks.

Filter head
is composed of filter cap, filter handle, filter cap seat and embedded parts. There are many slits on the filter cap to form an air-water mixing channel. The top of the filter handle is integrated with the filter cap. There are one to three air inlet water holes in the middle and upper parts, and two to three air inlet water slits near the bottom. The end orifice can allow water to enter. Because the filter head used for air-water backwashing has a longer filter handle (generally
≧

), this type of filter head is also called a long-handled filter head< br/>.

Working principle of long handle filter head
,
Long handle filter head
During air and water backwashing, as long as the air pressure is greater than the backwash water pressure , the air gathers and forms an air cushion layer under the filter plate and gradually thickens. When sleep gradually comes to the air inlet hole on the filter handle, the air begins to flow into the filter handle through the small hole, and then enters the filter layer through the filter cap. seam, and then enter the filter layer through the filter cap through the filter handle. If the air flowing in is equal to the air entering the filter handle, the water surface will not fall and form an air cushion.

The flushing process of the air-water backwash method can be divided into three parts: first, water floatation, and then air scrubbing and air-water backwashing. The top of the filter handle is integrated with the filter cap. There are two air inlet water holes in the middle and upper part, and three air inlet water slits near the bottom. The end holes can allow water to enter. Because air and water backwashing is required, the filter handle is generally larger than
,m
. Air and water can enter through the small holes and slits on the filter handle at the same time, and emerge from the slits on the filter cap.
