Description

Technical Field

[0001] This utility model specifically relates to an adjustable drain valve, belonging to the field of drain valve technology. Background Technology

[0002] Drain valves are key components for controlling liquid discharge and are widely used in building water supply and drainage, industrial pipelines, fire protection systems, and other fields. The core function of a drain valve is to regulate liquid flow through opening and closing actions to achieve sewage discharge, water level control, or pressure release. However, most existing drain valves can only determine whether or not to drain, but cannot adjust the drainage flow rate according to actual usage conditions, thus affecting user experience. In actual use, water may contain impurities, which can cause blockage of the drain valve over time, affecting the drainage effect. Moreover, the exterior of most existing drain valves is made of one-piece casting, which is inconvenient for disassembly and thus inconvenient for users to clean the interior. In view of this, this utility model is proposed. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by providing an adjustable drain valve that is easy to adjust and disassemble. The adjustment component can adjust the overlap of the water channels on the fixed and movable adjustment plates, thereby adjusting the drainage flow rate. At the same time, the active and passive mounting rings can be disassembled, making it convenient for users to clean the inside and use the valve.

[0004] This utility model achieves the above-mentioned objectives through the following technical solution: an adjustable drain valve, comprising an active mounting ring and a passive mounting ring, with a connecting component between the active mounting ring and the passive mounting ring. A fixed adjusting disc is provided inside the active mounting ring and the passive mounting ring. An adjusting component is installed on one side of each of the active mounting ring and the passive mounting ring, extending to the outside of the active mounting ring and the passive mounting ring on both sides. Limiting holes are evenly distributed on both outer sides of the active mounting ring and the passive mounting ring. In use, the structure is first assembled using the connecting component, and then installed on an external drain pipe. During use, the drainage flow rate can be adjusted using the adjusting component and the fixed adjusting disc, thus facilitating user operation. After use, the structure can be disassembled using the connecting component, facilitating cleaning by the user.

[0005] Furthermore, in order to install this structure on an external drain pipe, a connecting funnel pipe is fixedly installed on one side of both the active mounting ring and the passive mounting ring, and one end of the connecting funnel pipe is connected to the external drain pipe.

[0006] Furthermore, in order to install the adjustment component on the active mounting ring and the passive mounting ring, a planar bearing is embedded on one side of both the active mounting ring and the passive mounting ring, and a T-shaped rotating groove is provided on one side of both the active mounting ring and the passive mounting ring, the T-shaped rotating groove being located inside the planar bearing.

[0007] Furthermore, in order to facilitate the rotation of the rotating disk and enable the two rotating disks to engage, the adjustment assembly includes a rotating disk, one side of which is rotatably engaged in the T-shaped rotating groove, and one side of the rotating disk is fixedly connected to one side of the planar bearing. The rotating disk has engagement holes arranged in a circumferential array on one side, and engagement pins are provided in the engagement holes.

[0008] Furthermore, in order to improve the sealing degree and reduce leakage, sealing rings are fixedly installed on both sides of the rotating disk, and one side of the sealing ring is in close contact with one side of the active mounting ring and the passive mounting ring.

[0009] Furthermore, in order to adjust the drainage rate, a movable adjustment plate is fixedly installed inside the rotating disc, and water channels are evenly opened on both the movable adjustment plate and the fixed adjustment plate.

[0010] Furthermore, in order to secure the rotating disk, a connecting rod is fixedly installed on the outer side of the rotating disk, and an mounting plate is fixedly installed on the other end of the connecting rod. The mounting plate is located on the outer side of the active mounting ring and the passive mounting ring, and one end of the mounting plate is slidably engaged with a limiting rod. The limiting rod cooperates with the limiting hole, and a tension spring is sleeved on the limiting rod. The two ends of the tension spring are fixedly connected to one side of the mounting plate and one end of the limiting rod, respectively.

[0011] Furthermore, in order to connect the active mounting ring and the passive mounting ring, the passive mounting ring is provided with evenly spaced positioning holes. The connecting assembly includes an internally threaded sleeve and a connecting bolt. The internally threaded sleeve is fixedly installed on the passive mounting ring and mates with the positioning holes. The connecting bolt is disposed in the positioning holes and is threadedly connected to the internally threaded sleeve.

[0012] Beneficial effects: The overlap of the water channels on the fixed and movable adjustment plates can be adjusted by adjusting the components, thereby adjusting the drainage flow rate. At the same time, the active and passive mounting rings can be disassembled, making it convenient for users to clean the inside and making it convenient for users to use. Attached Figure Description
