Abstract

PURPOSE:To increase the fluid filtration area of a filtration part as a whole and to prolong the life of the title filter element by providing plural fluid filtration parts to the filter element, and successively using the fluid filtration parts with use of a pressure valve. CONSTITUTION:Plural fluid filtration parts 2 and 4 are provided to the filter element 1 having lid bodies 6 and 7, and the pressure valve 8 for sending a fuid into the spaces partitioned by the fluid filtration parts 2 and 4 and the lid bodies 6 and 7 by the pressure change is furnished at an optional site. When the primary filtration part 2 is clogged, the fluid is charged by the action of the pressure valve 8 into the spaces partitioned by the primary filtration part 2, the secondary filtration part 4, and the lid bodies 6 and 7, and the fluid is directly filtered by the secondary filtration part 4. Consequently, the filtration area at the filtration part is increased as a whole, and the service life of the filter element 1 can be prolonged.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a filtration element having a pressure valve for causing fluid to flow into a space partitioned by a plurality of fluid filtration sections and a lid body through pressure changes.

Conventional elements had only one filtration section, and the life of the element itself was reached when the filtration section became clogged.

In view of these circumstances, the present inventor provided a filtration element having a lid with a plurality of fluid filtration parts, and created a space partitioned by the fluid filtration parts and the lid to cause fluid to flow into the space by a pressure change. Install a pressure valve at any location,
- If the next filtration section becomes clogged, the pressure valve is activated by the pressure change to allow fluid to flow into the space partitioned by the primary filtration section, the secondary filtration section, and the lid, and the fluid is transferred to the second filtration section. We have completed the present invention, which aims to perform filtration directly in the filtration section.

That is, the present invention provides a filtration element with a plurality of fluid filtration parts, and uses these fluid filtration parts in sequence with a pressure valve, thereby expanding the fluid filtration area of the filtration part as a whole and extending the life of the filtration element. The purpose is to

Note that the term "lid body" used in the text means something similar to a lid.

At the set pressure, the pressure valve 8 opens and the fluid 13 flows in the direction 15 and is directly filtered by the second filter section 4 via the pressure valve 8.

When the present invention is used in place of a normal filter element, the life of the filter element 1 can be extended in proportion to the area of the second filter section 4.
