Description

Technical Field

[0001] The invention relates to the technical field of ship valves, in particular to a leakage-proof ship valve. Background Art

[0002] Marine valves are devices used to control the pressure, flow and flow direction of fluids in ship pipelines to meet the environmental conditions of ships. Valves are control devices for fluid pipelines. Their basic functions are to connect or cut off the flow of pipeline media, change the flow of media, change the flow direction of media, adjust the pressure and flow of media, and protect the normal operation of pipeline equipment. Valve materials include cast iron, carbon steel, alloy steel, copper alloy, aluminum alloy, titanium alloy, stainless steel, and non-metals. Applicable media are mainly fresh water, sea water, steam, fuel oil, lubricating oil, etc. Ball valves and butterfly valves with the advantages of light weight, small size, good sealing performance, quick and convenient opening and closing, have gradually been used on ships, and will increasingly replace stop valves and gate valves to improve the performance of ships. Remote control valves such as electric gate valves, electric stop valves, electric sea valves, electro-hydraulic ball valves, electro-hydraulic butterfly valves, and pneumatic butterfly valves have also been gradually adopted by some ship systems, and hydraulic valve remote control systems have begun to be used, which has improved the modernization level of ships. The performance requirements of various ship systems require special valves, such as high-pressure butterfly valves, pilot-operated full-lift safety valves, seawater solenoid valves, high-pressure electro-hydraulic ball valves, rotary hydraulic gate valves, special pressure reducing valves, temperature regulating valves, high-pressure air solenoid valves, large-displacement steam traps, and phoenix butterfly valves, etc., can also be developed independently and provided for ship use.

[0003] When the existing anti-leakage marine valve is in use, such as the application number CN202410959050.6 discloses an anti-leakage marine valve, which relates to a marine valve, including a valve housing with connecting pipes fixedly connected on both sides, a fixed box fixedly installed in the valve housing, and a sliding rod slidably inserted in the fixed box; the present invention can make the electromagnet block abut against the fixed box by turning on the first electric push rod. During this process, the electromagnet block will push the slider to slide and compress the supporting spring and abut against the electromagnetic button, which can facilitate the electromagnetic button to control the battery to energize the electromagnet block, and then the energized electromagnet block will attract the iron sheet to The upward movement makes the iron sheet drive the slide plate to stretch the reset spring and drive the slide rod to move upward, thereby causing the blocking piece and the sealing ring to rotate upward and release the blocking on both ends of the valve body to facilitate drainage. In the above process, no manual operation is required, which reduces the work intensity of the personnel and avoids leakage due to wear, thereby improving the sealing of the marine valve. However, in the above technology, the blocking piece mainly closes the pipeline through a hinge drive, but because it is on the inner side of one end, its force is not balanced, which is easy to cause slight leakage. For this reason, we propose a leakage-proof marine valve to solve the above problem. Summary of the invention
