Low-energy-consumption, high-performance solenoid valve

By designing the limit baffle and drive components, and combining them with the partition and buffer components, the problem of overheating in the normally closed solenoid valve coil is solved, extending the coil's service life and reducing damage to the valve core and partition, thus achieving a low-energy-consumption, high-performance solenoid valve design.

AI Technical Summary

Technical Problem

Normally closed solenoid valves require prolonged power supply during operation, which causes the coil to heat up and reduces their service life.

Method used

The design employs a combination of a limit baffle, a rotating shaft, and a driving component, which allows the valve core to press against the limit baffle under the action of the return spring after the coil is de-energized. This reduces the energy consumption when the solenoid valve remains open. Furthermore, the combination of a partition, a buffer, a limit block, and a buffer pad reduces the collision between the valve core and the partition, extending the service life of the coil.

Benefits of technology

This reduces the continuous energizing time of the coil, lowers the risk of overheating, extends the coil's lifespan, and reduces the likelihood of damage to the valve core and partition.

Abstract

This application relates to the technical field of valves, and in particular to a low-energy-consumption, high-performance solenoid valve, including a valve body, a moving component, and a limiting component. The valve body has an inner cavity, within which the moving component and the limiting component are respectively disposed. A fluid flow channel communicating with the inner cavity is provided at the end of the valve body furthest from the inner cavity, and a baffle is disposed within the fluid flow channel. The moving component includes a movable iron core slidably disposed within the inner cavity, a fixed iron core disposed at the end of the valve body furthest from the fluid flow channel, and a return spring disposed between the movable and fixed iron cores. A valve core is disposed at the end of the movable iron core furthest from the return spring, and the valve core abuts against the baffle. The fixed and movable iron cores are coaxially arranged, and a coil is wound on the fixed iron core. The return spring is used to push the movable iron core to move. The limiting component includes a limiting baffle, which is movably mounted on the inner wall of the inner cavity. The limiting baffle is used to limit the valve core after it disengages from the baffle. This application has the effect of reducing the potential for a decrease in the lifespan of the coil.
