Description
Technical field
The present invention relates to a kind of high-voltage switch gear, simply, reliability is high, the high pressure of long service life for more particularly, to a kind of structure
Switch.
Background technology
The operation principle of pressure switch is：When in system, pressure is higher than specified safe pressure, video disc wink in induction apparatuss
When be moved, by connection guide pull switch joint disconnect, when pressure is down to specified recovery value, video disc wink reset,
Switch automatically resets, or is briefly when by measuring pressure overrate, and the free end of flexible member produces displacement, directly
Connect or promote switch element after relatively, change the on off operating mode of switch element, reach control by the purpose of measuring pressure.Pressure
Switch is the device combining with electric switch, when reaching Fluid pressure set in advance, make and break contact action, and it mainly should
Report to the police or control signal for output on the industrial equipments such as power plant, petrochemical industry, metallurgy industry, have important use in industrial circle
On the way, the damage of important device in production engineering can be prevented, it is to avoid great production accident ground occurs.Pressure switch generally comprises machine
Tool formula, electronic type two big class, mechanical pressure switches therein are that purely mechanic deformation leads to microswitch action, when pressure increases
When, act on different sensing pressure components and parts (diaphragm, corrugated tube, piston) and produce deformation, startup will be moved up topmost
Microswitch, make electric signal output.But the triggering loose piece being used for triggering microswitch in existing high-voltage switch gear is usually one
End is rotatably connected on valve body, and the other end is connected on valve body by compression spring elasticity, pushes away during sensing pressure components and parts deformation
Dynamic triggering loose piece rotates and triggers microswitch upwards, because triggering loose piece adopts the fixing rotation in one end to connect, therefore its lifting
The inevitable microswitch contact relatively of process and sensing pressure component surface produce and slide, and lead to both stress constantly to become
Change, so that trigger sensitivity is declined, the surface abrasion simultaneously being produced by friction, also reduce the service life of high-voltage switch gear.
