Description

Technical Field

[0001] The utility model relates to the technical field of float valves, and particularly relates to an underwater controller. Background Art

[0002] A float valve is a valve device controlled by liquid level. Its working principle is usually: the float moves up and down with the liquid level, and then drives the valve stem and the valve core to open or close the valve, so as to achieve the purpose of automatically controlling the liquid level.

[0003] The float valve has the advantages of simple structure, low cost, accurate control, etc., and is widely used in water storage devices such as water tanks and water towers to control the water level within a certain range and prevent water from overflowing or the water level being too low. Common float valves include products of different materials and specifications such as plastic float valves and stainless steel float valves to adapt to different working environments and requirements. However, when the float gets stuck due to scale or stains in the water (in outdoor water storage devices, it can also be water plants) during the ascending and descending stroke under the action of buoyancy, the valve cannot be automatically opened and closed, that is, there will be a situation where the water in the water storage device overflows or is too low, which is not easy to be discovered by the staff and there are potential safety hazards.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are only a part rather than all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0023] Please refer to FIGS. 1-2. An underwater controller includes: a housing 1. A valve stem 4 is slidably arranged horizontally inside the housing 1. One end of the valve stem 4 passing through the housing 1 is connected to a first floating ball 2. A floating ball monitoring assembly is slidably arranged vertically inside the housing 1. A trigger switch 6 is arranged at the top of the inner cavity of the housing 1. An alarm 5 electrically connected to the trigger switch 6 is fixedly connected to the top of the housing 1. When the valve stem 4 fails to interrupt the water flow due to a fault, the floating ball detection assembly will interrupt the water flow and trigger the alarm 5 to give an alarm.

[0024] Specifically, a controller is arranged inside the alarm 5. The controller is connected to the trigger switch 6 through an electric wire. The float valve in the prior art includes a housing 1, a first floating ball 2, and a valve stem 4. As the liquid level in the water tank rises, the first floating ball 2 drives the valve stem 4 to slide, so that the valve stem 4 blocks the water inlet in the housing 1, thereby preventing the outside from continuing to inject water into the water tank.

[0025] In the present utility model, when the first floating ball 2 is affected by scale or stains in the water and cannot work, the floating ball monitoring assembly continues to move upward under the action of buoyancy until the water outlet of the housing 1 is closed and the alarm 5 is triggered to inform the staff that there is a problem with the float valve, significantly improving the safety of the float valve.

[0026] Further, the floating ball monitoring assembly includes a plunger 31. A threaded rod 32 is threadedly connected to the top of the plunger 31. The bottom of the plunger 31 is fixedly connected to a second floating ball 3. The threaded rod 32 is threadedly connected to the top of the plunger 31, so that the distance between the top of the threaded rod 32 and the top of the plunger 31 changes, thereby changing the distance between the alarm trigger water level and the pre-stored water level. The pre-stored water level is the highest water level that the water tank can store when the first floating ball 2 is working. The alarm trigger water level is the water level in the water tank when the plunger 31 blocks the water outlet of the housing 1, that is, when the first floating ball 2 is not damaged and the valve stem 4 blocks the water inlet of the housing 1, the plunger 31 does not completely block the water outlet of the housing 1, and there is a certain distance between the threaded rod 32 and the trigger switch 6.

[0027] Further, a straight notch 42 is formed on the valve stem 4. When the second floating ball 3 drives the threaded rod 32 to rise, the threaded rod 32 passes through the straight notch 42.

[0028] In a further solution provided by the present utility model, a water outlet 11 and a water inlet 12 are formed in the housing 1. The water inlet 12 is located on one side of the valve stem 4, and the water outlet 11 is formed on the stroke path of the plunger 31. As the water level in the pool rises, both the first floating ball 2 and the second floating ball 3 float upward. The first floating ball 2 drives the valve stem 4 to slide horizontally, and the second floating ball 3 drives the plunger 31 to slide vertically. When the valve stem 4 blocks the water inlet 12, the plunger 31 does not completely block the water outlet 11.

[0029] In a further solution provided by the present utility model, a sealing gasket 43 is fixedly connected to the end of the valve stem 4 located inside the housing 1. A guide ring 41 is sleeved on the middle position of the valve stem 4, and the guide ring 41 is slidably arranged inside the housing 1. By providing the guide ring 41, the stability of the valve stem 4 sliding inside the housing 1 is improved, and the service life of the floating ball valve is extended.

[0030] In a further solution provided by the present utility model, the first floating ball 2 is rotatably arranged on the housing 1, and the top of the first floating ball 2 is inserted into one end of the valve stem 4 passing through the housing 1. When the first floating ball 2 floats upward under the action of buoyancy, the first floating ball 2 rotates around the housing 1, and the end of the first floating ball 2 inserted into the valve stem 4 drives the valve stem 4 to slide horizontally, realizing the opening and closing of the water inlet 12 by the sealing gasket 43.

[0031] In a further solution provided by the present utility model, the materials of the first floating ball 2 and the second floating ball 3 are alloy or plastic.

[0032] In a further solution provided by the present utility model, the diameter size of the second floating ball 3 is smaller than that of the first floating ball 2. The second floating ball 3 plays a role only when the first floating ball 2 fails. Therefore, in order to save costs, the diameter size of the second floating ball 3 can be smaller, as long as it can drive the plunger 31 to slide.

[0033] In the present utility model, referring to Figure 1 and Figure 2 , when the first floating ball 2 is stuck by scale or stains in the water, the water inlet 12 cannot be blocked, the water level in the pool gradually rises, the buoyancy of the second floating ball 3 drives the plunger 31 to move upward, the plunger 31 blocks the water outlet 11, and the threaded rod 32 presses the trigger switch 6 to trigger the alarm 5 to emit an alarm, reminding the staff that there is a problem with the floating ball valve.

[0034] Only some exemplary embodiments of the present utility model are described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
