Description

Technical Field

[0001] The utility model relates to the technical field of marine valves, in particular to a marine valve with an anti-corrosion function. Background Art

[0002] During the operation of ships, marine valves are an indispensable part of the ship system and are widely used in various fluid control systems, such as seawater circulation, cooling systems, fuel supply systems, etc. However, due to the particularity of the ship's operating environment, marine valves are often in a high-humidity, high-salinity, and highly corrosive marine environment, which places extremely high demands on the anti-corrosion performance of marine valves.

[0003] Traditional marine valves mainly rely on material selection and surface treatment for corrosion resistance. Although these measures have improved the anti-corrosion performance of the valve to a certain extent, various impurities such as sediments, scale, corrosion products, etc. are easily accumulated in the valve after long-term use. These impurities will not only affect the normal operation of the valve and reduce its fluid control performance, but also aggravate the corrosion of the valve. The flow and static state of the fluid inside the traditional marine valve will form dead corners in certain areas, causing impurities to accumulate here, making it difficult to discharge.

[0010] Preferably, multiple groups of filter screens are connected by fixing rods, and a circular plate is fixedly installed on the outer surface of one group of filter screens, and a handle is fixedly installed on the outer surface of the circular plate. The fixing rods are used to strengthen the connection between the filter screens to ensure the stability of the filter mechanism under high pressure or high flow rate, which helps to extend the service life of the filter mechanism and reduce damage caused by vibration or impact.

[0011] Preferably, the two ends of the handle are arc-shaped, and the outer surface of the handle is wrapped with rubber.

[0015] 1. The utility model generates stirring effect inside the sewage pipe by driving the stirring blades with a motor. This design can actively mix the impurities and corrosive substances in the wastewater or waste liquid evenly, thereby reducing their concentration. Reducing the concentration can reduce the corrosion of these substances on the valve material and extend the service life of the valve.

[0016] 2. The utility model can reduce the frequency of cleaning and maintenance of the valve by reducing the accumulation of impurities inside the valve, thereby improving the convenience of maintenance. At the same time, the design of the stirring mechanism also makes the cleaning process easier, because the rotation of the stirring blade can help discharge impurities from the inside of the valve.

The drain pipe 2 fixedly installed at its bottom end is used to discharge wastewater or waste liquid that may be generated inside the valve, and is used to connect other pipes. The water valve 4 arranged at the middle end of the drain pipe 2 can control the timing and discharge amount of sewage. In order to more effectively prevent corrosion and accumulation of impurities inside the valve, the valve is designed with a connecting shell 3 on the outer surface of the drain pipe 2.

These stirring blades 513 produce a strong stirring effect inside the drain pipe 2, evenly mix the impurities and corrosive substances in the wastewater or waste liquid, reduce their concentration, and thus reduce corrosion to the valve.
