Description
Technical field
The utility model belongs to fire-proof apparatus technical field, relates in particular to a kind of for monitoring labeled door in the contact of open mode electromagnetic valve.
Background technology
At present, after labeled door is opened, whether Surveillance center's monitoring in open mode, can not monitor labeled door in open mode less than labeled door by Surveillance center, is unfavorable for that monitor staff manages concentratedly by control centre, exists hidden fire-fighting danger.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of for monitoring labeled door in the contact of open mode electromagnetic valve, and it can make monitor staff monitor labeled door in open mode by Surveillance center.
The utility model is to realize like this, a kind of for monitoring labeled door in the contact of open mode electromagnetic valve, comprise an electromagnet, described electromagnet middle part offers a non-through installing hole vertically, described installing hole upper end offers a through hole coaxial with it, the diameter of described through hole is less than the diameter of described installing hole, in described installing hole, be provided with a contact switch, described contact switch outer peripheral edges are arranged with a spring, described contact switch top is provided with a thimble, described thimble comprises the first push rod and second push rod coaxial with described the first push rod, described the first push rod is positioned at described spring upper end and arranges with described contact switch interval, the top butt of the upper end of described the first push rod and described installing hole, described the second push rod protrudes from described through hole, described spring lower end and a back-up ring butt that is fixedly arranged on described contact switch middle part, described installing hole bottom is installed with one for the set screw spacing to contact switch backstop, in described set screw, offer the endoporus of a perforation, described contact switch bottom is through the endoporus of described set screw, described contact switch lower end is installed with two contact pins, described in two, contact pin is electrically connected with a signal circuit respectively.
Further, described set screw lower end offers a fastening port being disposed radially.
It is a kind of for monitoring labeled door in the contact of open mode electromagnetic valve that the utility model provides, it can make control centre monitor labeled door in open mode, facilitate monitor staff to manage all labeled doors concentratedly by control centre, in the time of breaking out of fire, can make labeled door close in time, stop hidden fire-fighting danger.
Brief description of the drawings
In order to be illustrated more clearly in the technical solution of the utility model, to the accompanying drawing of required use in embodiment be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
