Abstract
The utility model discloses an air pressure control switch, which comprises a bottom seat and a nose spike, a differential pressure spring, a conduction tray and a membrane arranged in the bottom seat, wherein the differential pressure spring and the conduction tray are arranged at the upper end of the membrane, a hole is arranged at the lower end aligned with a cover cap, and the nose spike is aligned with the conduction tray. The utility model has the advantages that the pressure induction is sensitive and accurate, the structure is simple and reasonable, the debugging is convenient and reliable, and the connection method with the outside and the azimuth position are concrete and various, etc.
Description
Technical field
The utility model relates to a kind of gas pressure control switch, particularly a kind of new-type structure low pressure type pressure control switch.
Background technology
Traditional low pressure type gas pressure control switch often adopts the air pressure induction mechanism to drive the sensitive switch of an integral body in order to reach the target of setting, realizes break-make, complex structure, and debug difficulties, hypobaric induction is insensitive, inaccurate.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, convenient pressure control switch that can satisfy negative pressure of Installation and Debugging.
For achieving the above object, technical solution adopted in the utility model is: a kind of air-pressure controlling switch, it comprises base and is contained in base interior thimble, pressure spring, conductive plate, diaphragm, diaphragm upper end dress pressure spring and conductive plate, the hole that the lower end aligned cover cap has, thimble is aimed at conductive plate.
It is sensitive and accurate to the utlity model has induction pressure, simple and reasonable, debug convenient and reliable, with advantages such as the concrete diversity of extraneous connecting mode and orientation.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Air-pressure controlling switch shown in the drawings is to be made of base 1, thimble 2, pressure spring 3, pressure reduction screw 4, conductive plate 5, diaphragm 6, cover cap 7 etc.Diaphragm 6 is pressed on the centre by base 1 and cover cap 4, and the cavity with switch is separated into two atmospheric pressure cavities simultaneously.One end of thimble can contact with conductive plate.The utility model switch is in off-state.Promote diaphragm 6 and conductive plate 5 by regulating pressure reduction screw 4 and pressure spring 3, change the pressure size of the distance adjustment switch of conductive plate 5 and thimble 2.A pressure reduction screw 4 also is housed on the base 1, and pressure reduction screw 4 just in time withstands pressure spring 3.
The utlity model has a positive air pressure chamber and a negative pressure chamber, connect by interface and corresponding positive negative pressure system, with the operation of control system.When the system that is controlled is negative pressure, along with the increase of system vacuum degree, overcome spring force under the differential pressure action in diaphragm 6 positive and negative air-pressure chambeies and move right, conductive plate 5 is contacted with thimble 2, switch close and, provide and close and control signal; When the system that is controlled was malleation, along with the increase of system's air pressure, diaphragm 6 overcame spring force and moves right under the differential pressure action in positive and negative air-pressure chamber, and conductive plate 5 is contacted with thimble 2, and switch closure provides the closed control signal people.
The utlity model has multifarious connection or fixed form, thimble 2 protuberate basic units 1 can directly be welded on the circuit board, also can connect electric wire and plug terminal.The air interface of this switch can rotate at any angle.
