EspañolThe metal spigot can be designed as a rotating structure, mainly achieved through the following technologies:
1、 Mechanical structure design
A rotating joint (such as a bearing or hinge structure) is integrated between the spigot valve body and the water outlet nozzle. For example, the patented design connects a vertical plate with a horizontal plate and embeds a bearing to support the rotating rod, allowing the nozzle to rotate 360 ° horizontally.
The design of the dual axis rotation mechanism adopts a dual motor drive system: the first motor controls horizontal rotation, and the second motor drives the nozzle to flip vertically through belt transmission, achieving multi angle adjustment.
2、 Sealing technology
The rotating part of the dynamic sealing component adopts polymer metal composite sealing rings (such as PTFE material) to maintain sealing performance under high temperature and high pressure. For example, in the hybrid spigot patent, the transverse channel of the valve water channel and the rotating bridging part are leak proof through a flexible sealing ring.
The threaded cylinder structure is used between the threaded adjustment sealing rotating rod and the fixed part. When tightened, the sealing gasket is compressed to enhance the sealing performance, while allowing for rotational adjustment (such as the threaded rod design in the hardware accessory placement rack).
3、 Materials and processes
The key load-bearing components of the metal polymer hybrid structure, such as brackets and bases, retain metal materials (brass/stainless steel), while non pressure bearing rotating parts use engineering plastics (such as POM) to reduce frictional resistance and lower costs.
The surface treatment process involves chrome plating or nano coating on metal rotating parts to reduce wear and improve corrosion resistance, thereby extending the lifespan of the rotating mechanism.
4、 Application Cases
High temperature rotary joints in industrial scenarios are applied in petrochemical equipment, which can withstand temperatures above 300 ℃ and maintain rotational sealing performance by embedding ceramic bearings in metal shells.
The kitchen spigot in the civilian field adopts a "universal joint" design, and the metal nozzle is finely adjusted at a ± 15 ° angle through an internal ball joint to meet the multi angle water demand.
