Description
Technical field
This utility model relates to a kind of power supply pressure switch.
Background technology
Pressure switch adopts high accuracy, the pressure transducer of high stable performance and transmission circuit, then through dedicated cpu modular signal treatment technology, it is achieved the detection of pressure medium signal, display, warning and control signal are exported.Pressure switch can be widely applied in the fields such as oil, chemical industry, metallurgy, electric power, water supply, the measurement of various gases, the gauge pressure of liquid, absolute pressure be controlled, and is the desirable intelligent measurement and control instrument of industry spot.
Pressure switch is when in system, pressure is higher or lower than specified safe pressure, in induction apparatus, video disc is instantaneous is moved, it is switched on or switched off by connecting guide rod pull switch joint, when specified recovery value is down to or is risen to pressure, video disc instant reset, switch automatically resets, or it is briefly when by measuring pressure overrate, the free end of flexible member produces displacement, directly or through after promote switch element, change the on off operating mode of switch element, reach to control by the purpose of measuring pressure.
Current existing power supply pressure switch construction less stable, installs inconvenience, and degree of regulation is relatively low.
Utility model content
It is reliable that the technical problems to be solved in the utility model is to provide a kind of Stability Analysis of Structures, security performance height, easy for installation, the power supply pressure switch that degree of regulation is high.
For solving the problems referred to above, this utility model adopts the following technical scheme that a kind of power supply pressure switch, including upper cover, lower cover, threaded rod and piston, described upper cover is located at down and covers, described upper cover is threadeded with lower cover, described threaded rod is located at and covers, described threaded rod is threadeded with upper cover, described piston is located in upper cover, described piston and upper cover are slidably connected, compression spring it is provided with in described piston, described piston is connected with threaded rod by compressing spring, described threaded rod side is provided with binding post, it is provided with contact bottom described binding post, described binding post is electrically connected with piston by contact, described piston is arranged below diaphragm and outlet terminal.
As preferably, described outlet terminal is electrically connected with piston, facilitates circuit to connect unobstructed.
As preferably, described binding post side is provided with steady pin, keeps connection terminal structure stable.
As preferably, described binding post is connected by steady pin and upper cover are fixing, keeps Stability Analysis of Structures reliable.
As preferably, described binding post being provided with connecting sleeve, conveniently accessing cable, insulation effect is good.
The beneficial effects of the utility model are: upper cover and the lower cover of setting are threaded, compact overall structure can be kept, stability is high, diaphragm can extrusion piston, piston being connected with contact, keeps circuit unobstructed, threaded rod can rotate on upper cover, extruding compression spring makes piston move down, and reaches the effect of disconnecting circuit.
