Abstract
The utility model relates to an overwater protector, comprising a valve body, wherein, the valve body is provided with a valve column communicated with the valve body, and the other end of the valve column is provided with a magnetism sensing component. An inner chamber of the valve column is provided with a magnetic ring component, the magnetic ring component is provided with a contact of the magnetism sensing component, and the magnetic ring component is provided with magnetic rings and valve sheets fixed on and extended in the inner chamber of the valve body. The utility model taking as a shock-proof protector of an electric water heater has the advantages of simple structure, convenient installation and reliable operation.
Description
The utility model relates to a kind of relay, plays the relay of electrocution-proof protection effect especially for domestic, electric water heater.
Along with the continuous abundance of domestic electric power resource, electric heater will occupy the increasing share in pot-type boiler market.But for a long time, the electrocution-proof protection of electric heater is the focus that the consumer is concerned about always, also is the difficult point of water heater manufacturer.
The purpose of this utility model is a kind of water conservation device excessively that can play the electrocution-proof protection effect when using electric heater of design.
The technical scheme that realizes above-mentioned purpose is as follows: cross the water conservation device; has valve body; valve body is provided with the valve rod with its UNICOM; the other end of valve rod is equipped with the magnetic strength assembly; the valve rod inner chamber is provided with magnetic ring component; the magnetic strength assembly has magnetic strength assembly contact, and magnetic ring component has magnet ring and fixes on it and extend into the valve block of body cavity, and magnet ring is adjacent with magnetic strength assembly contact.
As the further technical measures of aforementioned schemes, described magnetic strength assembly contact has last contact and following contact.
On electric heater, use the utility model; when the user need use hot water; even may forget about or be inconvenient to close power supply; cross and produce current in the water conservation device; current drive the protector valve block, make the magnet ring on the valve block produce displacement and rely on magnetic strength assembly contact, and rely on the action of a magnetic field to make the last contact and following contact closure of magnetic strength assembly contact; order about the power supply that the electric heater electric control system is cut off electric heater, reach the effect of electrocution-proof protection.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 be anhydrous when mobile magnetic ring component and magnetic strength assembly contact concern schematic diagram;
Magnetic ring component and magnetic strength assembly contact concerned schematic diagram when Fig. 3 flowed for water;
Below in conjunction with description of drawings embodiment: valve body 1 is provided with the valve rod 2 with its UNICOM, the other end of valve rod 2 is equipped with magnetic strength assembly 3, valve rod 2 inner chambers are provided with magnetic ring component 4, and magnetic strength assembly 3 has magnetic strength assembly contact 31, and magnetic strength assembly contact 31 has last contact 311 and following contact 312.Magnetic ring component 4 has magnet ring 41 and fixes on it and extend into the valve block 42 of valve body 1 inner chamber, and magnet ring 41 is adjacent with magnetic strength assembly contact 31.
When having water to flow in the valve body 1, current make valve block 42 lower ends be offset towards water (flow) direction, thereby make magnet ring 41 reverse water flow path directions and rely on magnetic strength assembly contact 31, make contact 311 and following contact 312 closures, make the electric heater electric control system cut off the power supply of electric heater by circuit again with last contact 311 and following contact 312 conductings.
Fig. 2, Fig. 3, among the figure, arrow A is represented water (flow) direction, arrow B is represented the magnet ring direction of displacement.
