An easy-to-assemble water control valve

Abstract

This utility model relates to a water control valve that is easy to assemble. It mainly solves the problems of low assembly pass rate and poor reliability of existing water control valves assembled using hooks and holes. It includes a valve body (1) and a float chamber (2). The valve body (1) has a first protrusion (3) and a second protrusion (4) on its lower sides. The float chamber (2) has symmetrically positioned, open-topped locking holes (5) on its upper sides. The two locking holes (5) correspond to the first protrusion (3) and the second protrusion (4), respectively, and the first protrusion (3) and the second protrusion (4) can fit into the two locking holes (5). This utility model provides symmetrical locking holes on the side wall of the float chamber. During assembly, the first and second protrusions below the valve body are pushed into the locking holes on the float chamber, saving time and effort during assembly, resulting in a high assembly pass rate, preventing the valve body from easily detaching, and ensuring reliable connection.

Description

Technical Field

[0001] This utility model relates to a device for automatically controlling water level, specifically a water control valve that is easy to assemble. Background Technology

[0002] Automatic water control valves are valves that automatically control the water level entering the container. They are widely used in various industries. Automatic water control valves control the opening and closing of the valve orifice by the rise and fall of a float. When the water level in the container reaches the set level, the float, under the action of buoyancy, automatically closes the valve. When the water level in the container falls below the set level, the float sinks under its own weight, the valve opens, and the valve automatically opens, allowing water to enter the container. Existing water control valves mainly consist of a valve body, a float chamber, and a diaphragm valve core assembly. The valve body and float chamber are generally made of PVC injection molding. In traditional water control valves, the float chamber and valve body are connected using ordinary self-tapping screws. During assembly, the self-tapping screws are screwed directly into the valve body through the float chamber. This requires drilling holes before screwing in the screws, which is time-consuming and labor-intensive. Furthermore, the float chamber needs to have a pre-drilled groove to accommodate the screws, making the float chamber structure complex and increasing the difficulty of mold making. To address the aforementioned technical problems, Chinese patent CN201920898457.7 discloses an environmentally friendly food-grade water control valve. At least two hooks are provided on the lower edge of the valve body, with the hooks being an integral part of the valve body. The outer wall of the float chamber has corresponding locking holes on the hooks. After the valve body and float chamber are engaged, the hooks fit into the locking holes. This hook-and-lock connection structure replaces the original screw connection structure, saving time and effort in assembly, simplifying the float chamber structure, facilitating mold making, and reducing processing costs. However, the above structure still has the following technical defects: 1. The integral structure of the hooks and valve body places high demands on the injection mold, and the fitting precision requirements between the hooks and the locking holes on the float chamber are also high, resulting in a low product assembly qualification rate. 2. Due to material limitations, the hooks themselves have weak elastic recovery ability. After repeated disassembly and assembly, the hooks lose their elasticity, and the valve body and float chamber are prone to detachment, leading to poor product reliability. Utility Model Content

[0003] To overcome the shortcomings of existing water control valves with hook and pin connections, which have low assembly pass rates and poor reliability, this utility model provides a water control valve that is easy to assemble. This easy-to-assemble water control valve has symmetrical snap-fit ​​holes on the side wall of the float chamber. During assembly, the first and second protrusions below the valve body are pushed into the snap-fit ​​holes on the float chamber. Assembly is time-saving and labor-saving, with a high assembly pass rate, the valve body is not easy to fall off, and the connection is reliable.

[0004] The technical solution of this utility model is: a water control valve that is easy to assemble, including a valve body and a float chamber. The valve body has a first protrusion and a second protrusion on both sides of its lower part. The float chamber has symmetrical and open snap-fit ​​holes on both sides of its upper end. The two snap-fit ​​holes correspond to the first protrusion and the second protrusion respectively. The first protrusion and the second protrusion can fit into the two snap-fit ​​holes.

[0005] The lower part of the snap-fit ​​hole is a circular hole, and the opening width of the snap-fit ​​hole is smaller than the diameter of the circular hole; both the first protrusion and the second protrusion are cylinders.

[0006] The lower part of the snap-fit ​​hole is a regular hexagonal hole, and the opening width of the snap-fit ​​hole is smaller than the diagonal length of the regular hexagonal hole; both the first protrusion and the second protrusion are regular hexagonal.

[0007] This invention offers the following advantages: The float chamber features a snap-fit ​​hole structure. During assembly, the first and second protrusions are aligned with the snap-fit ​​holes on the float chamber. A certain thrust is applied, causing elastic deformation of the float chamber sidewall above the snap-fit ​​holes. After the first and second protrusions are fully inserted into the snap-fit ​​holes, the float chamber sidewall returns to its original shape, and the two snap-fit ​​holes respectively engage with the first and second protrusions, completing the assembly. This invention saves time and effort during assembly, has a high assembly qualification rate, prevents the valve body from easily detaching, and ensures reliable connection.

[0010] The present invention will be further described below with reference to the accompanying drawings:

[0011] Depend on Figure 1As shown, a water control valve that is easy to assemble includes a valve body 1 and a float chamber 2. The valve body 1 has a first protrusion 3 and a second protrusion 4 on its lower sides. The float chamber 2 has symmetrical, open-topped locking holes 5 on its upper sides. The two locking holes 5 correspond to the first protrusion 3 and the second protrusion 4, respectively, and the first protrusion 3 and the second protrusion 4 can be fitted into the two locking holes 5. Due to the above technical solution, during assembly, the first protrusion 3 and the second protrusion 4 are aligned with the locking holes 5 on the float chamber 2. A certain pushing force is applied to cause elastic deformation of the side wall of the float chamber 2 above the locking holes 5. After the first protrusion 3 and the second protrusion 4 are fully inserted into the locking holes 5, the side wall of the float chamber 2 returns to its original shape, and the two locking holes 5 are respectively fitted into the first protrusion 3 and the second protrusion 4, completing the assembly. This utility model saves time and effort in assembly, has a high assembly qualification rate, prevents the valve body from easily detaching, and ensures reliable connection.

[0012] The lower part of the snap-fit ​​hole 5 is a circular hole, and the opening width of the snap-fit ​​hole 5 is smaller than the diameter of the circular hole; both the first protrusion 3 and the second protrusion 4 are cylindrical. In the design, the pipe body of the water inlet pipe and the pipe body of the water outlet pipe can be respectively set as the first protrusion 3 and the second protrusion 4, so as to make the structure more compact.

[0013] The lower part of the snap-fit ​​hole 5 is a regular hexagonal hole, and the opening width of the snap-fit ​​hole 5 is smaller than the diagonal length of the regular hexagonal hole; the first protrusion 3 and the second protrusion 4 are both regular hexagonal prisms. In the design, the hexagonal prisms on the water inlet pipe and the water outlet pipe can be set as the first protrusion 3 and the second protrusion 4 respectively, so as to make the structure more compact.
