Embodiment Construction

[0009] exist figure 1 Among them, the present invention is a seawater pipeline filter, which is composed of two filters 1 and two three-way valves 2, the four are connected as one by flanges, the two filters 1 and the two three-way valves 2 The two valves are connected, and the third valves of the two three-way valves 2 are the inlet 6 and the outlet 7 respectively. The three-way valve 2 is also provided with a wrench 3, and the wrench 3 is provided with a valve inside the three-way valve 2. To switch the two valves of the three-way valve 2, the wrench 3 is arranged on the three-way valve 2 as the inlet. A filter cartridge 4 is fixed in the filter 1 by bolts, and a discharge screw plug 5 is arranged between the two.

[0010] Such as figure 2 As shown, under normal circumstances, the control handles of the two three-way valves are turned to the left position, and the filter 1 works. sea ​​water from figure 1 The inlet flow shown then flows through filter 1 and the lower 3-...

Abstract

The invention discloses a seawater pipeline filter, consisting two filters (1) and two three-way valves (2) which are connected into a whole by flanges, wherein the two filters (1) are communicated with two valves of the two three-way valves (2); third valves of the two three-way valves (2) are respectively an inlet (6) and an outlet (7); the three-way valves (2) are also provided with spanners (3); and the spanners (3) are provided with valves in the three-way valves (2), and the valves are used for opening and closing the two valves of the three-way valves (2). The invention provides a seawater pipeline filter applicable to complex water areas and can clean obstructions under the condition that the water flow in the seawater pipeline is not cut off.

Description

technical field [0001] The invention relates to a seawater pipeline filter suitable for complex waters, especially in waters with many shellfish and algae marine organisms. In the case of marine organisms clogging the filter, it can be used without shutting off the main seawater valve. Seawater filter to clear blockages. Background technique [0002] At present, most of the ships manufactured by domestic shipyards, whether they are on international routes or domestic routes, use the suction coarse water filter (CB / T497-94 or CBM1061-81) in the seawater pipeline filter. The filters are all single-connected, that is, there is only one filter channel. Once the seawater is blocked by shellfish and seaweed, the seawater cannot enter the required seawater cooling and fire protection systems, and the consequences are disastrous. And other seawater filters must be connected in parallel with a bypass pipe in the seawater pipeline, and a filter and two At the same time, two valves h...
