Novel type filter valve

Abstract

The invention discloses a novel type filter valve which relates to a filter valve and solves the problems that excrement of ornamental fish in a domestic ornamental fish tank cannot be decomposed, andduring the use process of the filter valve, a large number of excrement is easy to cause the blockage of the filter valve so as to further influence a filtration effect of the filter valve. The invention provides the technical scheme point that the novel type filter valve comprises a valve body, wherein the valve body is provided with an inflow port for a fluid to enter, and an outflow port for the fluid to flow out; filter sand for filtering the excrement of the ornamental fish and a filter fine screen for filtering micro impurities are arranged in the valve body; the clearance of the filtersand is larger than the pore of the filter fine screen; the filter sand and the filter fine screen are sequentially arranged along the water flowing direction; water sequentially passes through the filter sand and the filter fine screen, the ornamental fish excrement in water is firstly filtered through the filter sand, then the micro impurities are filtered through the filter fine screen, and blockage is not easy to occur due to the large clearance between the filter sand, so that the normal use of the filter valve is ensured.

Description

technical field [0001] The invention relates to a filter valve, in particular to a novel filter valve. Background technique [0002] Filter valve, also known as filter, is a device used for pre-filtering. It is a must-have filter device for hydraulic control valves and precision mechanical products that are easily blocked. It is also an indispensable part of the pipeline series for conveying media. This device is usually installed at the inlet end of hydraulic control valves, pressure reducing valves, pressure relief valves, fixed water level valves and other equipment to eliminate impurities in the medium and prevent granular impurities from entering the channel and causing wall plugs to protect equipment pipelines Fittings are protected from wear and clogging. [0003] In the family ornamental fish tank, the filter valve can also be used to filter and purify the water quality in the fish tank, but the excrement of the fish cannot be decomposed. During the use of the filte...

Problems solved by technology

[0003] In the family ornamental fish tank, the filter valve can also be used to filter and purify the water quality in the fish tank, but the excrement of the fish cannot be decomposed. During the use of the filter valve, a large amount of excrement will easily cause the blockage of the filter valve, which will affect the filtration. Filter effect of the valve
