Description
Technical field
The utility model is related to a kind of pressure sensor, more particularly to a kind of diaphragm pressure signalling means.
Background technology
Conventional pressure judgment mode is pressure sensor at present, by pressure sensor acquisition system pressure, to pressure
The output parameter of sensor is identified and read, then judges whether system normally supplies.Existing air-channel system needs supporting one
Planting is used to judge the pressure signal device whether system normally supplies, and when upstream valve opens system supply, passes through pressure signal
Device experiences valve downstream pressure, exports high level signal；When upstream valve is closed, system supply is interrupted, and pressure signal device enters
Mouth exports low level signal without pressure.In some cases, work times requirement 10000 times, pressure after upstream valve is opened
Signalling means inlet pressure about 0.2~0.3MPa.But, using its signal acquisition of existing pressure sensor and judging system more
Complexity, cost is higher, therefore is not suitable for such a operating mode.
Utility model content

Further, the frizzen is T-shaped, and the big end of frizzen is contacted with housing cavity bottom surface, the big end bottom surface of frizzen
Provided with guiding gutter, throttle orifice is located at housing bottom center, and the guiding gutter is connected with throttle orifice, constitutes throttling passage.
Further, the frizzen is provided with attaching nut, and diaphragm is enclosed on frizzen and positioned at attaching nut with touching
Send out between the big end of bar, the diaphragm inner ring is fixed and sealed with frizzen by attaching nut.
Further, the diaphragm outer ring is fixed and sealed with housing by clamp nut.
Further, the structure of the diaphragm has three layers, and two layers is 5171 nitrile rubbers of examination up and down, and intermediate layer is 115 cottons
Cloth.
Further, the control circuit includes microswitch and two resistance being sequentially connected in series, and any resistance two ends connect
Connection control circuit signal output part.
The beneficial effects of the utility model are：Using diaphragm pressure signalling means, institute on diaphragm is delivered to by frizzen
The miniature deformation of generation, to realize the effective monitoring whether normally supplied to gas circuit, with being quick on the draw, simple and reliable for structure
Feature, it is simple and convenient using the control of collection method system, collection, the interpretation of electric resistance partial pressure.

Embodiment
The utility model is described in detail with reference to specific embodiments and the drawings.
As shown in figure 1, embodiment provides a kind of diaphragm pressure signalling means.
It is provided with the bottom centre of adpting flange 1 on throttle orifice 14, T-shaped frizzen 4 and is provided with water conservancy diversion on the other side
The toroidal cavity 16 that medium in groove 15, gas circuit or liquid-way system is entered in adpting flange 1 by throttle orifice 14 and guiding gutter 15,
Thus there is preferable cushioning effect to compression shock；Spring 3, attaching nut 7 and diaphragm 2 are sleeved on T-shaped frizzen 4 successively
On, one end of T-shaped frizzen 4 is contacted with microswitch 5, pretightning force and the lower contacts of adpting flange 1 that the other end passes through spring 3
And it is relative with throttle orifice, the inner ring of diaphragm 2 is connected and sealed with T-shaped frizzen 4 by attaching nut 7, and outer ring passes through clamp nut 8
Fix and seal with adpting flange 1, diaphragm 2 is using folder cloth structure in the middle of a kind of double-layer rubber, and two layers is 5171 butyronitrile of examination up and down
Rubber, centre is 115 cottons, and diaphragm external diameter Φ 21.5, internal diameter Φ 4 are installed on pressure signal device rear sensitive external diameter Φ 18, even
The diameter of phi 17.8 of connected nut 7, spring installing force 13N, microswitch 5 is arranged in mounting seat 10, suitably can be adjusted up and down, is protected
Demonstrate,proving T-shaped frizzen 4 can triggered as normal microswitch.Socket 11 is arranged on socket flange 9, and socket flange 9 and mounting seat 10 are pacified
On adpting flange 1.
As shown in Fig. 2 wire 13 is connected with the normal opened contact of microswitch 5, it is ensured that microswitch 5 is output as when not triggering
Low level, resistance R1 (reference 6) and resistance R2 (reference 12) are series relationship, and the output level of microswitch 5 can
It can also be gathered with the collection from resistance R2 two ends from resistance R1 two ends.Resistance R1 resistance 5.1k Ω, resistance R2 resistance 2.7k Ω, letter
Number supply voltage 12V.
When gas circuit or liquid-way system pressure are zero or when active force that pressure is produced is not enough to overcome spring force, T-shaped triggering
Bar 4 in pressure signal device lower end and does not trigger microswitch 5 under spring force, and pressure signal device is output as low electricity
It is flat；When the active force that gas circuit or liquid-way system pressure are produced overcomes spring force and triggers microswitch, circuit is connected, pressure letter
Number device output high level.It is applied in actual condition, can be reliably triggered under 0.1~0.4MPa of pressure, the height electricity of output
Flat about 4.15V, exports 0V low levels when pressure is 0MPa.
