Detailed description of the invention
Fig. 1 pneumatic type temperature relay main view
Fig. 2 is the circuit diagram of temperature sensor of the present invention
Specific embodiment
It elaborates below with reference to drawings and examples to the present invention:
Outlet-pipe 3, lead collar 5, outlet rod 6, porcelain tube 7, connector sleeve 8, film cover 10, diaphragm 11 collectively form actuating mechanism,
Wherein porcelain tube 7 is to guarantee that outlet rod 6 and film cover 10 insulate, the output end connecting with outlet rod 6 and the output connecting with diaphragm 11
End is the two poles of the earth of temperature relay, and external circuitry is connect with the two poles of the earth, when diaphragm 11 is overturn, is switched on or switched off entire circuit.It is dynamic
Make mechanism and a sealing structure is collectively formed in seal closure 12, air inlet pipe 13.Air inlet pipe 13 is mainly used for adjusting in seal closure
Gas pressure.Seal closure 12 and seat board 9 constitute seal cavity, for storing gas,
Specific embodiment is as follows:
First escape pipe 3 is vacuumized and welded, 11 side of safety action mechanism diaphragm is in vacuum state, then leads to
The seal chamber filling gas that air inlet pipe is constituted toward seal closure 12 and seat board 9 is crossed, is calculated and is sealed according to temperature relay alarm temperature
Intracavity gas stuffing pressure value.When ambient temperature variation, gas pressure is increased in seal chamber, and gas pressure acts on diaphragm 11
On, when gas pressure reaches the operating temperature of temperature relay, diaphragm 11 overturn simultaneously contacted with outlet rod 6, at this time with outlet
Bar 6 connect outlet-pipe 3, binding post 1 constitute a pole and be connected with diaphragm seal closure 12, film cover 10, seat board 9 composition one
Grade contact, entire circuit are in closed state.Temperature relay outwardly exports OFF signal.When ambient temperature variation, sealing
Intracavity gas pressure reduction, when gas pressure decline reaches the recovery temperature of temperature relay, the overturning of diaphragm 11 and and outlet
Bar 6 disconnects, and entire circuit is in an off state.Temperature relay outwardly exports OFF signal.
A kind of temperature relay with overtemperature alarm function, the sensor are made of actuating mechanism and seal cavity, benefit
The gas stored with seal cavity is increased pushing action mechanism by temperature change pressure, and alarm temperature point passes through control filling sealing
The movement threshold value collective effect of the intracorporal pressure of chamber and actuating mechanism forms.When environment temperature reaches heat spot, relay is dynamic
Make output switching signal prompt system environment overheat.
Compared with prior art, temperature relay of the present invention carries out overtemperature alarm using pneumatic principle, avoids traditional double
The metal temperature relay response time is slow, and measurement accuracy is low；Using gas as promotion source high reliablity, performance is stablized, is belonged to
A kind of New temperature relay.Temperature alarm quickly can be outwardly exported when environment temperature overheat, controls environment in time
Overheat is adversely affected caused by system.
