Description
Technical field
This utility model relates to FSE field, is especially a kind of mechanical type pressing gap sensor.
Background technology
, certain pressure reduction must be there is between the different structure of building, such as building in requirement in Building Design fire safety rules
Corridor must be kept the blast of more than 50Pa between ladder, and elevator cup must keep the blast of more than 25Pa to corridor.So
Design be because on fire mostly occurring in side, room, corridor, keep elevator cup and the staircase blast to corridor, can try one's best
Push down cigarette, avoid rear cigarette on fire to alter to elevator cup and corridor as far as possible, slow down intensity of a fire diffusion, it is simple to personnel withdraw.
But, the pressure reduction between each part mentioned above can not be excessive, and otherwise the door between each several part can be held down and push away not open,
Stop personnel withdraw in time.So, for ensureing safety, it is necessary to the building different piece inside and outside opposite house carries out pressure reduction prison in real time
Survey, once find that door both sides pressure reduction is excessive, then must open ventilation relief valve in time, it is ensured that door can normal folding.
Utility model content
The technical problems to be solved in the utility model is to provide the mechanical type pressure reduction of a kind of energy real-time monitoring door both sides pressure reduction
Sensor.
Technical solution of the present utility model is to provide a kind of mechanical type pressing gap sensor, and it includes housing and regulation
Screw, the inner chamber of housing is provided with one layer of barrier film, and inner chamber is divided into epicoele and cavity of resorption by barrier film, fixes an arc between housing two side
Shape shell fragment, arc spring lamination fixes with barrier film lower surface, and epicoele connects through the high-pressure side of upper Guan Yumen, and cavity of resorption is low through down tube and door
The connection of pressure side；Housing Base is through with a sleeve pipe, and the tube chamber epimere of sleeve pipe is screwed hole and hypomere is through hole, and regulation screw is worn
Crossing through hole to screw with screwed hole, screw stretches out the part of screwed hole and is provided with a baffle plate, is provided with sealing ring between screw and through hole,
Screw upper end is sheathed with first stage clip, the two ends of the first stage clip respectively with baffle plate and arc spring lamination against；
The inner chamber of housing is provided with push switch, this push switch include two installing plates of symmetry, symmetrical two second
Stage clip, cross striker and and be positioned at the contact below cross striker, contact and two installing plates and be each attached on housing, every
Second stage clip upper end and cross striker are fixed and lower end and installing plate are fixed, cross striker upper end and arc spring lamination against.
The operation principle of this sensor is, epicoele is connected with high-pressure side, and cavity of resorption is connected with low-pressure side, and both pressure reduction makes
Cross striker pressed under arc spring lamination by barrier film, when pressure is more than the marginal value of two second stage clips, presses under cross striker, touches
Encountering contact, circuit communication, the curent change of circuit can form a signal of telecommunication, reminds the pressure reduction of door both sides to have arrived at warning
Value, notifies that relief valve is opened, timely pressure release.
The mechanical type pressing gap sensor of above structure, is quick on the draw, and testing result is accurate, and, turning adjusting screw, rise
Downshift plate, regulates the elasticity of the first stage clip, and then regulates the alarming value of this sensor so that it is adapt to the need of various pressure reduction monitoring
Want, improve its versatility.
