Aiming at the defects of the prior art, the utility model provides a water filter assembly, which has small pressure loss, strong dirt filtering ability, long service life of components, simple operation, convenient installation and maintenance, and is economical and practical.

Utility model content

In order to achieve the above object, the technical solution adopted by the utility model to solve the technical problems is:

A water filter assembly, including a base, a filter screen, a sewage valve, and a filter cover, the base is an engineering plastic base, and the base is provided with water inlet holes and water outlet holes; one end of the filter cover is connected to the engineering plastic base through a nut, The other end communicates with the drain valve; a filter screen is also arranged in the filter cover.

The end of the filter cover connected to the engineering plastic base is provided with a groove, and a sealing ring is arranged in the groove.

The material of the filter cover is transparent engineering plastics.

The upper end of the drain valve is provided with a handle, through which the filter of the utility model can control the discharge of dirt from the filter screen.

The filter screen is a stainless steel filter screen.

Compared with the prior art, the material of the base of the water filter assembly of the present invention is engineering plastics, which is resistant to acid and alkali corrosion, prolongs the service life of the component and reduces the cost; the purpose of protecting the high-pressure water pump is achieved by filtering the dirt through the stainless steel filter; There is a groove at one end of the filter cover, and a sealing ring is arranged in the groove, which has good sealing performance, small pressure loss, and strengthens the effect of filtering dirt, which meets the characteristics and requirements of the engineering operation vehicle; the overall structure of the water filter assembly of the utility model It is compact, easy to operate, economical and practical, and guarantees the service life of the product.

detailed description

The water filter assembly of the present utility model is described in detail below with reference to the accompanying drawings.

A water filter assembly, comprising engineering plastic base 1, nut 2, stainless steel filter screen 4, transparent filter cover 5, sewage valve 6; engineering plastic base 1 and transparent filter cover 5 are connected by nut 2, transparent filter cover 5 and One end connected to the engineering plastic base 1 is provided with a groove (not shown in the figure), and a sealing ring is arranged in the groove; the engineering plastic 1 is provided with a water inlet hole 3 and a water outlet hole 7; the stainless steel filter screen 4 is arranged in a transparent filter cover 5 ; The blowdown valve 7 communicates with one end of the transparent filter cover 5, and the blowdown valve 7 is provided with a handle 8 at the upper end.

When the utility model is used, it is installed before the water inlet of the high-pressure pump. The water to be filtered enters through the water inlet 3, flows through the stainless steel filter 4, and enters the pump body through the water outlet 7. The particulate impurities in the water are trapped in the stainless steel filter. The inside of the net 4, thereby effectively prolonging the service life of the water pump, and protecting the clean, safe and effective operation of the system.
