Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the utility model and not to limit the scope of the utility model. Moreover, in the following structures, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
The suction type coarse water filter shown in fig. 1-5 comprises a filter body 100, wherein the filter body 100 is provided with a coarse water inlet pipeline 110 and a filtered water outlet pipeline 120.
The water outlet end 112 of the raw water inlet pipeline 110 is connected to the inside of the filter cartridge 130, the filter cartridge 130 is provided with a plurality of filter apertures, and the specific size of the filter apertures can be adjusted according to different filter materials. The ratio of the passage area of the filter cartridge 130 to the nominal diameter area is not less than 3.
The water inlet end 121 of the filtered water outlet line 120 is disposed in the cavity between the inner wall of the filter body 100 and the filter cartridge 130 and the water inlet end 121 of the filtered water outlet line 120 is tangent to the wall of the filter cartridge 130.
With particular reference to fig. 2-4, the raw water inlet tube, 110 and the filtered water outlet tube 120 are disposed symmetrically or at right angles (the arrow in the figure indicates the filtering direction).
The water inlet end 111 of the raw water inlet pipe 110 is provided with a first flange 191, and the water outlet end 122 of the filtered water outlet pipe 120 is provided with a second flange 192.
The upper portion of the filter body 100 is detachably provided with a sealing cap 150 by a sealing gasket 140. Specifically, the sealing cover 150 is controlled to be opened or closed by an opening device 160.
The opening unit 160 includes a split pin 161 disposed on an outer wall of the filter body 100, a pin 162 disposed on the split pin 161, a swing bolt 163 and a ring nut 164 disposed on the pin 162, and a gland plate 167, a first washer 165 disposed at an end of the swing bolt 163, and a second washer 166 disposed at a contact end of the swing bolt 163 and the ring nut 164, and opens or closes the sealing cap 150 by controlling the tightness of the gland plate 167.
A right-angle ferrule cut-off valve 170 is provided on the sealing cap 150, and the inside of the filter cartridge 130 is connected or closed to an external pipe through the right-angle ferrule cut-off valve 170.
