Description
Technical field
The utility model relates to a kind of pressure type switch, particularly relates to a kind of pressure-controlled mains switch.
Background technology
Along with the extensive use of electric energy in producing, living, mains switch has also become the universal use of electricity consumption apparatus indispensable necessaries, particularly household electrical appliance, and the quality of mains switch performance is used the assurance of electrical equipment especially safely.Current exploitation along with electric heater is upgraded, and that existing switch has been difficult to be applicable to is high-power, high level of synchronization is disconnected automatically in current, the requirement of energize.What use in the electric heater at present all is indirect energized switch, this switch complex process, and technical data is wanted inaccuracy, just easily goes wrong if any error, so that have an accident.
Summary of the invention
The purpose of this utility model provides a kind of safe and reliable pressure-controlled mains switch, simultaneously, the utlity model has advantage easy to use.
The technical scheme that realizes the utility model purpose is as follows:
Pressure-controlled mains switch, comprise housing with cavity, one end setting of this housing has the connector of fluid passage, the other end of housing is provided with end cap, the hole that lead passes on the end cap extend in the conducting cavity of housing, be provided with the bimetal leaf of sealing gasket in the described housing, the cavity that forms between this bimetal leaf and the housing is a pressure chamber, also be provided with the fixed bolster that a piston and has through hole in the described housing, the push rod that is fixed in the piston left side is connected with described bimetal leaf, be provided with cavity volume between piston right side and the fixed bolster, be provided with conductive liquid in this cavity.
Described conductive liquid is a mercury.
Also be provided with a sealing gasket in the cavity of described housing, the sealing pad is between end cap and fixed bolster.
Adopted such scheme, be provided with the bimetal leaf of sealing gasket in the described housing, the cavity that forms between this bimetal leaf and the housing is a pressure chamber, behind the gas or liquid inlet pressure chamber of pressure, bimetal leaf is stressed or is subjected to heat effect generation deformation, and the push rod that causes bimetal leaf to promote piston moves piston, and the effect that conductive liquid is stressed flows out to the conducting cavity from the through hole of fixed bolster, the lead that is arranged in conducting cavity is all charged, and circuit is connected.
When the utility model and the supporting use of electric heater, the water filling pressurization is promptly logical, and decompression is promptly disconnected, and automatic control is highly sensitive, simplifies operation link, and conducts electricity very well, and production Technology is less demanding, and is safe and reliable, simple and reasonable, volume.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
