Abstract
The invention relates to an external magnetic attack-preventing air, water and heat meter with a motor actuator and a control valve. According to the n external magnetic attack-preventing air, water and heat meter of the invention, a plurality of anti-magnetic sheets made of magnetic conductive materials are fixed around a motor (4) of a valve actuator; one or a plurality of bent anti-magnetic sheets made of magnetic conductive materials are fixed at the outer side of a sealed box body; when a strong magnet approaches the motor (4) of the valve actuator, due to the blocking of the anti-magnetic sheets around the motor (4) and the bent anti-magnetic sheets at the outer side of the sealed box body, magnetic line of forces emitted by the strong magnet can be absorbed by the anti-magnetic sheets, and the directions of the magnetic line of forces can be changed by the anti-magnetic sheets, and as a result, the strength of the magnetic line of forces arriving at the motor (4) can be greatly decreased, and therefore, the motor (4) can be protected from being subjected to magnetic attack.
Description
Technical field:
The invention belongs to instrument and meter envelope accessory, the aqueous vapor hotlist that the anti-outer magnetic relating in particular to a kind of translator actuator and by-pass valve control is attacked.
Background technology:
At present; for the intelligentized water, electricity and gas measuring instrument in various place; great majority all lay particular emphasis on the protection to sample circuit (sample circuit major part adopts magneto sensor) and main circuit board in the strong magnetic disturbance in the anti-external world; and the protection ignored motor on valve actuator, but the motor on actuator is also the interference that can be subject to extraneous high-intensity magnetic field.Facts have proved, when the motor on valve actuator suffers extraneous intensive magnetism attack, particularly suffer that very strong magnet is attacked the outside of motor on valve actuator (kicker magnet is placed in by) time, the motor of valve actuator just loses the function of rotation, during the action opened or closed when needing valve, valve just cannot realize, thus loses the proper function of valve.
The invention provides a solution, it can not only prevent extraneous high-intensity magnetic field on the impact of main circuit board, it also can be prevented the impact of the motor on valve actuator simultaneously.
Summary of the invention:
The present invention is achieved in that it is around the motor of valve actuator, the anti-magnetic sheet that fixing multi-disc permeability magnetic material is made, and outside sealing box body, fixes the anti-magnetic sheet of bending that one or more pieces are made with permeability magnetic material.When there being kicker magnet close to motor on valve actuator; owing to there being the stop of the anti-magnetic sheet around motor and the anti-magnetic sheet of bending outside sealing box body; the magnetic line of force that kicker magnet sends will be absorbed by these anti-magnetic sheets and make it change direction; the intensity that the magnetic line of force arrives motor place can reduce greatly, thus reaches the object protecting motor attacked by magnetic.Because main circuit board is also within these anti-magnetic sheets, so these anti-magnetic sheets also electrically serve good antimagnetic protective effect to main circuit board etc.

Embodiment:
The present invention is achieved in that it is around the motor (4) of valve actuator, the anti-magnetic sheet that fixing multi-disc permeability magnetic material is made, and outside sealing box body, fixes the anti-magnetic sheet of bending (3) that one or more pieces are made with permeability magnetic material.When there being kicker magnet close to motor (4) on valve actuator; owing to there being the stop of the anti-magnetic sheet around motor (4) and the anti-magnetic sheet of bending (3) outside sealing box body; the magnetic line of force that kicker magnet sends will be absorbed by these anti-magnetic sheets and make it change direction; the intensity that the magnetic line of force arrives motor (4) place can reduce greatly, thus reaches the object that protection motor (4) suffers magnetic attack.Because main circuit board is also within these anti-magnetic sheets, so these anti-magnetic sheets also electrically serve good antimagnetic protective effect to main circuit board etc.
