Description

Technical Field

[0001] The utility model belongs to the technical field of tugboats and relates to a water injection overflow stop valve. Background Art

[0002] A tugboat is a multi-purpose workboat specifically used for towing other ships or floating buildings, and it is widely used in aspects such as inland waterway shipping, port work, marine rescue, and marine development. When a tugboat is in use, fresh water needs to be injected. Generally, a water tap is connected to a water pipe for direct water injection. However, since the water injection time is relatively long and there is no special reminder after the water is full, once the crew starts to leave, they often forget that the water is being injected and the water overflows; but if the crew keeps watching and waiting, it will waste a lot of the crew's time and affect the crew's rest. Therefore, there is a large room for improvement. Summary of the Invention

[0030] The specific embodiments described herein are only illustrative of the spirit of the present utility model. Those skilled in the technical field to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar ways to replace them, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.

[0031] As Figures 1 - 5 shown, a water injection overflow stop valve includes: a valve body 100, a movable assembly, a connecting pipe 300, and a quick connector 400.

[0032] Among them, the valve body 100 is provided with a water inlet 110, a movable cavity 120, and a water outlet 130, and the water inlet 110, the movable cavity 120, and the water outlet 130 are integrally communicated.

[0033] Among them, the movable component includes a valve core 210 and a floating body 220. The floating body 220 is connected to the valve core 210. The valve core 210 is arranged in the movable cavity 120. The floating body 220 can drive the valve core 210 to seal the water inlet 110 or the communication port between the water outlet 130 and the movable cavity 120.

[0034] Among them, one end of the connecting pipe 300 is connected to the valve body 100.

[0035] Among them, the quick connector 400 is used to connect with a water pipe. The quick connector 400 is connected to the other end of the connecting pipe 300.

[0036] In this embodiment, it is connected to the water pipe through the quick connector 400, and then the faucet connected to the water pipe is opened to release water. When the water rises to a certain level, the floating body 220 drives the valve core 210 to seal the water inlet 110 or the communication port between the water outlet 130 and the movable cavity 120, so as to cut off the water flow. There is no need for the crew to monitor in real time to close the faucet, and at the same time, the water level is accurately controllable.

[0037] As Figures 1 - 5 shown, on the basis of the above embodiment, the movable component further includes a rotating arm 230 and a linkage block 240. The rotating arm 230 is rotatably connected to the valve body 100. One end of the rotating arm 230 is rotatably connected to the linkage block 240. The other end of the rotating arm 230 is connected to the floating body 220. The linkage block 240 is movably connected to the valve core 210.

[0038] As one specific implementation manner, the valve core 210 is provided with a linkage groove 211. The linkage block 240 is arranged in the linkage groove 211 and can move relative to the radial direction of the valve core 210. The floating body 220 can drive the rotating arm 230 to rotate and make the linkage block 240 move so as to drive the valve core 210 to move.

[0039] In this embodiment, the floating body 220 can drive the rotating arm 230 to rotate and make the linkage block 240 move so as to drive the valve core 210 to move. By the linkage block 240 offsetting the movement of the rotating arm 230 in the radial direction relative to the valve core 210, the valve core 210 only moves relative to the valve body 100 so as to seal the water inlet 110 or the communication port between the water outlet 130 and the movable cavity 120.

[0040] As another specific implementation manner, the linkage block 240 can be directly hinged to the rotating arm 230. At this time, it is necessary to ensure that the movement amount of the linkage block 240 in the radial direction relative to the valve core 210 is small.

[0041] As Figures 1 - 5As shown, on the basis of the above-described embodiment, the floating body 220 is detachably connected to the rotating arm 230.

[0042] In this embodiment, the floating body 220 is detachably connected to the rotating arm 230, so the floating body 220 of different volumes can be replaced according to requirements.

[0043] As Figures 1 - 5 shown, on the basis of the above-described embodiment, the quick connector 400 includes a connector body 410 and a fastening sleeve 420.

One end of the connector body 410 is provided with a fitting chamfer 411, and the inner wall of the fastening sleeve 420 is provided with a fastening portion 421 that gradually becomes larger from the end where the fitting chamfer 411 is located on the connector body 410 towards the other end.

[0044] In this embodiment, the water pipe is passed through the fastening sleeve 420 and sleeved on the connector body 410 through the fitting chamfer 411. Then, the fastening sleeve 420 is moved along the axial direction of the connector body 410 and the gap between the fastening portion 421 and the fitting chamfer 411 is reduced to achieve the connection between the quick connector 400 and the water pipe.

[0045] As Figures 1 - 5 shown, on the basis of the above-described embodiment, the connector body 410 is further provided with an external thread 412, and the fastening sleeve 420 is further provided with an internal thread 422. The connector body 410 and the fastening sleeve 420 are threadedly connected through the external thread 412 and the internal thread 422.

[0046] In this embodiment, the connector body 410 and the fastening sleeve 420 are threadedly connected through the external thread 412 and the internal thread 422. Therefore, by rotating the fastening sleeve 420 circumferentially around the connector body 410, the fastening sleeve 420 can be moved along the axial direction of the connector body 410, so that the fastening portion 421 approaches or moves away from the fitting chamfer 411.

[0047] As Figures 1 - 5 shown, on the basis of the above-described embodiment, the valve body 100 is further provided with a first connection portion 140, and the connecting pipe 300 is provided with a second connection portion 310.

[0049] As Figures 1 - 5 shown, on the basis of the above-described embodiment, a first sealing ring 500 is further included. The first sealing ring 500 is located between the connecting pipe 300 and the valve body 100, and the end of the connecting pipe 300 contacts the end of the valve body 100 through the first sealing ring 500.

[0050] In this embodiment, the end of the connecting pipe 300 contacts the end of the valve body 100 through the first sealing ring 500, thereby achieving the sealing between the connecting pipe 300 and the valve body 100, preventing external gas from entering and preventing internal water from overflowing.

[0051] As Figures 1 - 5 shown, on the basis of the above-described embodiment, the connecting pipe 300 is provided with a third connecting portion 320, and the quick connector 400 is provided with a fourth connecting portion 413. The quick connector 400 and the connecting pipe 300 are detachably connected to the third connecting portion 320 through the fourth connecting portion 413.

[0052] In this embodiment, the third connecting portion 320 may be a threaded hole, the fourth connecting portion 413 may be a threaded portion, and the fourth connecting portion 413 can be threadedly connected to the third connecting portion 320; the third connecting portion 320 may be a clamping groove, the fourth connecting portion 413 may be a clamping block, and the fourth connecting portion 413 can be clamped to the third connecting portion 320.
