Description

Technical Field

[0001] The utility model relates to the technical field of float valves, in particular to an adjustable float valve. Background Art

[0002] The float valve automatically controls the liquid level of the water tower or pool by a crank arm and a float. It is easy to maintain, flexible and durable, and has high liquid level control accuracy. It is widely used in chemical, petroleum, natural gas, metallurgy, and other industries, as well as long-distance natural gas pipelines containing hydrogen sulfide media, many impurities, and severe corrosion.

[0003] For example, a Chinese patent with publication (announcement) number CN108194691A discloses a float valve, which is characterized in that it includes a valve body with a valve core and a float driving part that drives the valve core to move. The valve core is located at the water inlet end of the valve body valve port. The special feature is that the float driving part includes a float and a connecting rod. The float drives the connecting rod to swing up and down facing the valve core. The connecting rod penetrates from the water outlet end of the valve body valve port and is fixedly connected to the valve core.

[0004] Although the above technical solution solves the corresponding technical problem, the above technical solution still has the following defects:

[0005] It is found that the float valve of the above technical solution can only be opened and closed in actual use. When it is used, the flow rate will change with the change of the liquid level, and automatic water supply cannot be achieved. Utility Model Content

[0006] The utility model aims to provide an adjustable float valve, wherein the water inlet is connected to an external water pipe, and the water outlet is connected to a water storage tank. When in use, water source is introduced through the water inlet, and the water source falls to the position of the water outlet through the annular partition, and is discharged into the water storage tank through the water outlet. As the water level inside the water storage tank increases, the water level inside the valve housing also increases accordingly, so that the sealing plate can be driven to move upwards and block the annular partition under the buoyancy of the float ring, thereby realizing automatic water cut-off. As the water level inside the water storage tank decreases, the sealing plate can be driven to move downwards under the gravity of the float ring and be separated from the blockage of the annular partition, thereby realizing automatic water addition. In this reciprocating manner, automatic water supply can be realized.

[0007] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0008] An adjustable float valve, comprising:

[0009] A valve housing, wherein a water inlet is arranged at the top of one side of the valve housing, a water outlet is arranged at the bottom of the valve housing, a float mechanism is arranged inside the valve housing, and an adjustment mechanism is arranged inside the valve housing and at a position corresponding to the float mechanism.

[0010] The above-mentioned adjustable float valve, wherein the float mechanism includes a sealing plate, a floating ring is fixedly connected to the bottom of the sealing plate, and limit assemblies are installed on both sides of the sealing plate.

[0011] The above-mentioned adjustable float valve, wherein the limit assembly includes a mounting bracket fixedly connected to the side of the inner wall of the valve housing, a sliding rod fixedly connected to the mounting bracket, a sliding sleeve slidably connected to the sliding rod, an L-shaped connecting rod fixedly connected to the side of the sliding sleeve, and the other end of the L-shaped connecting rod fixedly connected to the sealing plate.

[0012] The above-mentioned adjustable float valve, wherein the adjusting mechanism includes a threaded sleeve fixedly connected to the valve housing, an adjusting bolt is threadedly connected to the threaded sleeve, an adjusting frame is rotatably mounted on the bottom of the adjusting bolt through a bearing, and an annular partition matching the valve housing is fixedly connected to the bottom of the adjusting frame.

[0013] In the above-mentioned adjustable float valve, a sealing ring matching the inner wall of the valve housing is arranged at the edge of the annular partition.

[0014] In the above-mentioned adjustable float valve, both sides of the top of the adjustment frame are fixedly connected with limited telescopic rods, and the top of the limited telescopic rod is fixedly connected to the valve housing.

[0015] In the above-mentioned adjustable float valve, a sealing gasket matching the annular partition is fixedly connected to the top of the sealing plate.

[0016] The utility model has at least the following beneficial effects:

[0017] In the utility model, an adjustable float valve is realized, the water inlet is connected with the external water pipe, and the water outlet is connected with the water tank. When in use, water source is introduced through the water inlet, the water source falls to the position of the water outlet through the annular partition, and is discharged into the water tank through the water outlet. As the water level inside the water tank increases, the water level inside the valve shell also increases accordingly, so that the sealing plate can be driven to move upward and block the annular partition under the buoyancy of the float ring, so that automatic water cut-off can be achieved. As the water level inside the water tank decreases, the sealing plate can be driven to move downward under the gravity of the float ring and be separated from the blocking of the annular partition, so that automatic water addition can be achieved. In this reciprocating manner, automatic water supply can be achieved. At the same time, the height of the annular partition can be adjusted by rotating the adjusting bolt and under the action of the threads of the adjusting bolt and the threaded sleeve, so that the sealing plate rises to different heights for sealing, so that automatic water addition at different water levels can be achieved.
