Description

Technical Field

[0001] The utility model relates to the technical field of ship and marine engineering construction, in particular to a detachable water level float regulating device. Background Art

[0002] The ship's boiler hot well water, high-temperature cooling water, and low-temperature cooling water are all equipped with water tanks. During use, the water in the water tank will be lost to a certain extent, so the water tank needs to be supplied with water. If the consumed water is not replenished in time, or if the water tank leaks, resulting in insufficient water in the water tank, it will affect the safe operation of the ship.

[0003] The practice of monitoring the water level in the water tank is usually to set a low liquid level alarm, and remind personnel to add water through the alarm device when the liquid level drops. When using a low liquid level alarm, the crew needs to manually add water after receiving the low liquid level alarm, which is time-consuming and laborious; or a float regulator is set. If the liquid level is lower than the position of the float, the water inlet is automatically opened to complete the water replenishment. Since the water in the water tank is continuously consumed, the water level in the water tank will change frequently, making the float device frequently opened and closed, which is easy to cause damage and needs to be replaced frequently. The float device currently used is set inside the water tank and cannot be conveniently disassembled and taken out from the outside during maintenance. Instead, the manhole cover of the water tank needs to be opened for maintenance, which is time-consuming and labor-intensive and affects the normal operation of the ship. Utility Model Content

[0011] In summary, the utility model has the following beneficial effects:

[0012] 1. The float floats or sinks in the water tank according to the liquid level. When the water level drops, the float sinks, driving the connecting rod and lever to rotate and move the valve core. Water automatically flows into the water tank from the water inlet of the valve body, achieving the effect of automatic water replenishment. No additional operation is required, saving time and effort. When the water level float regulating device is damaged and needs maintenance, the bolts between the blind flange and the seat plate flange can be opened, and the water level float regulating device can be taken out as a whole through the through hole on the seat plate flange for inspection and maintenance, without opening the manhole cover of the water tank for maintenance. The maintenance is convenient, the operation is simple, and it saves time and effort.

[0013] 2. A gasket is provided between the blind flange and the seat flange. When the blind flange and the seat flange are connected, the gasket acts as a seal between the blind flange and the seat flange to prevent water in the water tank from leaking out from the through hole on the seat flange;

[0014] 3. The connecting pipe and the blind flange are fixedly connected. When the water level float adjusting device needs to be taken out of the water tank for maintenance, the blind flange and the connecting pipe can be taken down as a whole after removing the bolts between the blind flange and the seat flange. The operation is more convenient. At the same time, it also avoids the leakage problem caused by poor sealing between the connecting pipe and the blind flange. BRIEF DESCRIPTION OF THE DRAWINGS
