Referring to fig. 1 to 6, the marine water filter according to the embodiment of the present utility model includes a filter body 3, a filter screen 12, a gate valve 2, a gas release cock 4, a release flange cover 8, a release cock 11, a net mouth tightening rope 14, a flow rate adjusting device 15, a filter screen hanging nail 6, and the like. As shown in the figure, the inlet of the filter screen 12 is fixedly arranged on the flange surface of the filter inlet flange 1, the outlet of the filter screen 12 is provided with a net mouth tightening rope 14, the whole filter screen is paved to the discharge flange 7 from the filter inlet flange surface after passing through the gate valve 2, and the net mouth tightening rope 14 is fixed on the filter screen hanging nails 6 after being tightened to prevent the net mouth of the filter screen from being flushed to the filter outlet along with water flow. Meanwhile, the filter screen 12 is provided with a filter screen mesh 13 with a certain size, so that sundries in water can be filtered according to the design requirement of a water pipe. A gate valve 2 is designed on the discharging branch pipe below the filter body 3, the gate valve can control the on-off of the discharging branch pipe, and a discharging flange cover is designed at the tail end of the discharging branch pipe. By closing the gate valve and disassembling the discharging flange cover, impurities in the filter can be rapidly discharged by loosening the net mouth tightening rope of the filter screen, and the whole process does not influence the normal water supply of the pipeline. Further, the end of the discharge branch pipe is provided with a discharge flange cover 8 with a discharge cock 11, and the discharge cock 11 can rapidly discharge sediment deposited in the filter without disassembling the discharge flange cover 8. Furthermore, a gasket 10 for sealing is arranged between the discharging flange cover and the discharging flange, and the gasket is made of polytetrafluoroethylene, and the discharging flange cover and the discharging flange are connected by adopting a butterfly bolt 9, so that the discharging flange cover can be rapidly disassembled, a net opening tightening rope is untied, and garbage and sundries in the water filter are rapidly removed.

As an alternative implementation, in some examples, the filter body 3 is made of transparent engineering plastic, a vent cock 4 is designed above the filter body for rapidly releasing gas in the water filter, the total length of the filter is 400mm, the height is 300mm, the inlet and the outlet of the filter are connected with the system pipeline in a flange form, and the size of the flange can be customized according to the size of the matched flange in the system pipeline.

As an alternative embodiment, in some embodiments, a specially structured flow regulator 15 is designed in the middle of the outlet flange 5 of the water filter, and the flow regulator 15 is composed of two throttle plates, namely a flow regulator a plate 17 and a flow regulator B plate 18, and is installed in the middle of the outlet flange 5 in a butt-clamping manner through flange bolts 16. When the pipeline flow is required to be completely cut off, only the handles above the flow regulating device A plate 17 and the flow regulating device B plate 18 are required to be rotated along the flange surface direction of the outlet flange 5, so that the handle transmission rod grooves are respectively clamped on the 2 flange bolts 16 above the outlet flange 5, as shown in fig. 5. Similarly, when the flow area of the pipeline needs to be increased, the handles above the flow regulating device A plate 17 and the flow regulating device B plate 18 are rotated in opposite directions respectively to enable the flow regulating device A plate and the flow regulating device B plate to be overlapped, the throttling area of the pipeline can be quickly and accurately adjusted to 50%, and when the throttling area is 50%, the handles of the flow regulating device A plate and the flow regulating device B plate can be rotated in the horizontal direction at the same time, the throttling area is further enlarged to 100%, and the flow is maximized.

According to the water filter disclosed by the utility model, as the filter body 3 is made of transparent materials, the filter filth blocking condition and the filter screen breakage condition can be directly observed by naked eyes without disassembling the filter, when more garbage and sundries in the filter screen are observed, the gate valve 2 is closed, the discharging flange cover 8 is opened, and finally, the filter screen port tightening rope 14 is untied, so that the sundries in the filter can be rapidly discharged. After the cleaning of the garbage sundries in the filter is finished, the filter screen net opening tightening rope 14 is tightened, the flange cover 8 is assembled and disassembled, and the normal use of the filter can be recovered by opening the gate valve 2, so that the normal water supply of the pipeline is not affected in the whole filter cleaning process, and a large amount of water can not overflow due to the disassembling and washing of the filter. When breakage of the screen 12 is observed, the screen 12 can be easily removed and replaced by simply opening the gate valve 2 and disassembling the inlet flange 1.

In summary, the marine water filter provided by the utility model not only can rapidly and accurately regulate the water supply flow of the pipeline in a larger range, but also can conveniently and rapidly clean the filter on the premise of not influencing the normal water supply of the pipeline, remove garbage and sundries in the filter screen, discharge sediment deposited in the filter, and rapidly release the air in the filter and the pipeline through the deflation cock. Meanwhile, the filter blocking condition and the filter screen breakage condition can be directly observed by naked eyes, unnecessary filter maintenance work is reduced, clean and reliable cooling water with controllable and adjustable flow is effectively provided for ship equipment, and the safety of the ship cooling equipment is protected.
