Brief description of the drawings
Fig. 1 is the utility model structural representation, is the i.e. larger schematic diagram of the second chamber pressure under negative pressure state;
Fig. 2 is that the utility model is the larger sectional structure schematic diagram of the first chamber pressure under barotropic state;
Fig. 3 is original blast switch structural representation.
Embodiment
Comprise the shell 1 with built-in elastic diaphragm 2, the inner chamber of shell 1 is divided into the first cavity 13 and the second cavity 7 by this flexible sheet 2, on shell 1, be respectively equipped with the first cavity connecting interface 16 and the second cavity connector 6, on flexible sheet 2, establish intermediate plate 3, on intermediate plate 3, establish shell fragment post 11, between the inwall of shell fragment post 11 and the first cavity 13, be provided with a metal clips 4, this metal clips one end is fixedly connected with the inwall of this first cavity, the other end is connected with shell fragment post 11, in this second cavity, be furnished with the Hall magnetic force linear transducer 12 being connected with intermediate plate 3, this Hall magnetic force linear transducer is connected with the signal output splicing ear box 15 on shell 1 by flexible connection line 14, adjustment bolt 8 on shell is connected with magnetic links 5 by magnet steel base 10.
The end of described metal clips 4 is provided with pilot hole, the end socket of this pilot hole and shell fragment post, and there are locking plate 9 and the clamping of shell fragment post in this metal clips outside.
Principle of work: when blast is during in 0 handkerchief: be fixed on shell fragment 4 on housing and drive diaphragm folder 3 to make diaphragm 2 state that mediates, adjust bolt 8 and make the linear sensor movement of the relative Hall magnetic force of magnetic links, can obtain needed zero signal, at this moment blast is 0 handkerchief.
In the time that the second chamber internal gas pressure is greater than the first cavity air pressure (negative pressure), referring to Fig. 1, the resistance that air pressure in the second cavity can overcome metal clips 4 drives intermediate plate 3 and diaphragm 2 to move to the first cavity, at this moment due to the motion of intermediate plate 3, Hall magnetic force linear transducer 12 also can change the distance of relative magnetic links 5 accordingly, when the relative distance of Hall magnetic force linear transducer 12 and magnetic links 5 changes, the output signal of Hall magnetic force linear transducer 12 will be exported corresponding position electric signal by flexible connection line, because the signal of Hall magnetic force linear transducer and the relative distance of magnetic links are linear relationships, so signal is also linear relationship.
In the time that the first cavity internal gas pressure is greater than the second cavity (malleation), referring to Fig. 2, intermediate plate and diaphragm can move to the second cavity 7, the relative distance of Hall magnetic force linear transducer 12 and magnetic links 5 can change, Hall magnetic force linear transducer can be exported corresponding electric signal, exports by flexible connection line.
By adjusting the elastic force of shell fragment 4, the blast that can realize in different range detects.
The utility model can be realized the different range of blast is detected to output signal, avoid original blast switch, can only detect a value range, thereby can realize micro-pressure-difference and gather electronization, can be widely used in all kinds of wall-hung boiler water heaters, gas fired-boiler and wall-hung boiler heating system micro-pressure-difference detect, have advantages of detection accurately and reliably, simple in structure, with low cost, applied range.
