Description

Technical Field

[0001] This utility model relates to the field of float control valves, and in particular to a long-lasting and durable water tank inlet float control valve. Background Technology

[0002] The water tank inlet float control valve controls the opening and closing of the valve by the up-and-down movement of a float, thereby achieving automatic water level control. When the liquid level in the tank drops, the float drops accordingly, the valve stem moves down, and the valve seat opens, allowing liquid to flow into the tank. When the liquid level rises, the float rises, the buoyancy of the float increases, and eventually the float floats up, driving the valve stem up, closing the valve seat, and stopping the flow of liquid.

[0003] Traditional inlet float control valves often have some design shortcomings, such as insufficient adjustment precision, inability to quickly and accurately adjust the water level in the tank, and inconvenience in repairing or replacing them when the float ball is damaged and lacks buoyancy after long-term use, as well as limited durability. Therefore, there is an urgent need to develop a water tank inlet float control valve that can quickly and accurately adjust the water level, while also being easy to disassemble and maintain and improving durability. Utility Model Content

[0004] This invention aims to overcome the shortcomings of traditional inlet float control valves, such as insufficient adjustment precision, inability to quickly and accurately adjust the water level in the tank, and inconvenience in repair and replacement when the float ball is damaged and lacks buoyancy after long-term use.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings: Example

[0019] A long-lasting and durable water tank inlet float control valve, such as Figure 1-2 As shown, it includes an inlet valve 1 for water to enter the water tank; and a float control device 2 disposed on one side of the inlet valve 1 for controlling the water entering the inlet valve 1.

[0020] The inlet valve 1 includes a valve body 11, with a mounting cavity at its center and an outlet pipe communicating with the mounting cavity on one side of its outer diameter surface. A mounting seat 12 is located inside the mounting cavity of the valve body 11, with an inlet hole at its lower end and an outlet hole communicating with the outlet pipe on one side. A sealing seat 13 is fixedly installed at the inlet hole of the mounting seat 12. A sealing block 14 is also slidably installed inside the mounting seat 12. An isolation diaphragm 15 is fixedly installed at the upper end of the mounting seat 12. A valve stem 16 is slidably installed at the upper end of the valve body 11, penetrating the valve body 11 and communicating with the mounting cavity. A connecting rod 17 is also located at the lower end of the mounting seat 12, with a water passage hole communicating with the inlet hole of the mounting seat 12 at its center. The connecting rod 17 and the mounting seat 12 are fixedly connected to the valve body 11 by a locking sleeve 18.

[0021] The float control device 2 includes a pressure rod 21 hinged to the upper end of the valve body 11; one end of the pressure rod 21 is located at the upper end of the valve stem 16 and contacts the upper end face of the valve stem 16; the other end of the pressure rod 21 is located on one side of the valve body 11 and is fixedly connected to a connecting block 22 by a connecting pin 23; a sliding hole is provided in the center of the connecting block 22, and a sliding rod 24 is slidably arranged in the sliding hole; a float ball 25 is fixedly connected to the lower end of the sliding rod 24; a threaded hole is also provided on one side of the connecting block 22, which is connected to the sliding hole of the connecting block 22, and a locking bolt 26 is provided in the threaded hole.

[0022] Working principle:

[0023] The present invention is a water inlet float control valve, which consists of two main parts: a water inlet valve 1 and a float control device 2. In use, the water inlet valve 1 is fixedly installed on the housing, and the float ball 25 of the float control device 2 is fixedly installed in the water guide box.

[0024] When water is introduced, it enters through the water inlet of the connecting pipe, and the water flow breaks through the sealing block 14 at the water inlet of the mounting base 12, enters the valve body 11, and is discharged into the water tank through the water outlet pipe provided on the valve body 11. When the water level in the water tank reaches the preset height, the float 25 in the water tank generates an upward force under the action of buoyancy. The float 25 drives the slide rod 24 and the connecting block 22 locked to the slide rod 24 to generate an upward force, so that the pressure rod 21 and the connecting block 22 generate an upward force at the connection end, and the other end of the pressure rod 21 presses down, squeezing the valve stem 16. After being squeezed, the valve stem 16 slides downward, squeezing the convex part on the diaphragm. When the diaphragm protrudes, it presses against the sealing block 14, causing the sealing block 14 to move downwards and engage with the sealing seat 13 to block the water inlet of the mounting seat 12. The water inlet valve 1 stops supplying water and no longer pumps water into the water tank. When the water level in the water tank drops, the float 25 moves downwards with the water level. The slide rod 24, which is fixedly connected to the float 25, and the connecting block 22, which is locked to the slide rod 24, also move downwards and no longer apply upward force. This prevents the other end of the pressure rod 21 from pressing against the valve stem 16. The water flow then reopens the sealing block 14 at the water inlet of the mounting seat 12 and pumps water into the water tank, thereby achieving the effect of controlling the water level in the water tank to be stable.

[0025] Simultaneously, by loosening the locking nut and adjusting the position of the slide rod 24, the height of the float 25 can be adjusted, thereby controlling the water level in the tank. When the float 25 needs to be replaced or repaired after long-term use, the connecting pin 23 can be pulled out to separate the pressure rod 21 and the connecting block 22, and then the connecting block 22 and the float 25 can be removed, achieving the effect of easy disassembly and maintenance and improving durability.

[0026] Although this disclosure has been described in detail with reference to exemplary embodiments, it is not limited thereto, and it will be apparent to those skilled in the art that various modifications and changes may be made thereto without departing from the scope of this disclosure.
