Domain is applied.
Existing diaphragm pressure sensor is when carrying out fatigue test, calibra tion when technique, elastomer and impulse
Mouth, which must weld together, could lead to pressure and tested and examined and determine.When leaking occurs in product or performance is bad, elastomer and
Other components are together scrapped, and increase the cost of product.
Therefore, a kind of welding technique is developed, assembles the simple and reusable pressure sensing of each component of sensor
Device is of crucial importance.
The plainly-packed solderless manufactured between sensor elastomer and gland and pressure-inducing nozzle using the seal form of " O " type rubber ring
Connect pressure sensor can solve the problems, such as it is above-mentioned.
Utility model content
The purpose of this utility model is to provide a kind of plainly-packed welding pressure sensor, in view of the deficiencies of the prior art,
The problems such as solving pressure sensor elastomer must weld with pressure-inducing nozzle, and each component cannot be reused, and production cost is high.
To solve above technical problem, the technical solution of the utility model is：A kind of plainly-packed welding pressure sensor, bag
Include center with tracting pressuring hole, upper end is provided with the circular seal groove for being provided with the first sealing ring, middle part outer edge is provided with and is provided with the
The pressure-inducing nozzle of the circular seal groove of two sealing rings, elastomer, the tapped gland in lower end, upper end are provided with the pressure cap group of outlet hole
Into, it is characterised in that：The elastomer upper end outer circumferential is welded with the stent of support circuit board；The elastomer is using sputtering
The pressure sensitive core of thin film technique manufacture, when ambient pressure acts on the elastomer by the tracting pressuring hole, the bullet
Property body deform upon, the output electric signal proportional to pressure；The electric signal passes through institute by lead and outer lead
Outlet hole is stated outwards to export.
The pressure-inducing nozzle top is machined with external screw thread, and the gland puts on the pressure cap and is screwed in the outer spiral shell of the pressure-inducing nozzle
When on line, the gland compresses downwards the pressure cap and the elastomer, and the elastomer and first sealing ring are close
Contact, formation are fully sealed.The gland is in close contact with second sealing ring, and formation is fully sealed.
Compared with prior art, had the beneficial effect that possessed by the utility model：It will be passed as a result of " O " type sealing ring
Sensor elastomer and gland are carrying out tired examination with pressure-inducing nozzle by rubber seal rings for seal and the form of screw threads for fastening, product
Test, calibra tion when technique, when occurring leaking or performance is bad, component can be convenient for changing, without will
Sensor is integrally scrapped, and substantially reduces production cost.
Brief description of the drawings
Fig. 1 is the structure diagram of the plainly-packed welding pressure sensor of the utility model.
In figure：1st, pressure-inducing nozzle, 2, elastomer, 3, gland, 4, pressure cap, 5, stent
6th, circuit board, 7, lead, 8, outer lead, the 9, first sealing ring
10th, the second sealing ring, 11, outlet hole, 12, tracting pressuring hole, 13, internal thread

Embodiment
As shown in Figure 1, the plainly-packed welding pressure sensor of the utility model, by pressure-inducing nozzle 1, elastomer 2, in the band of lower end
The gland 3 of screw thread 13, the pressure cap 4 that upper end is provided with outlet hole 11 form.1 center of pressure-inducing nozzle carries tracting pressuring hole 12, and upper end is opened
There is the circular seal groove for being provided with the first sealing ring 9, middle part outer edge is provided with the circular seal groove for being provided with the second sealing ring 10.
The elastomer 2 is using the pressure sensitive core of Sputtering Thinfilm Technology manufacture, 2 upper end outer circumferential of elastomer
It is welded with the stent 5 of support circuit board 6.The power supply of elastomer 2 and output electric signal are connected by lead 7 and circuit board 6, and
Signal is outwards exported by the outlet hole 11 by outer lead 8.
1 top of pressure-inducing nozzle is machined with external screw thread 14, and the gland 3 puts on the pressure cap 4 and is screwed in the pressure-inducing nozzle 1
External screw thread 14 on when, the gland 3 compresses downwards the pressure cap 4 and the elastomer 2, the elastomer 2 and described the
One sealing ring 9 is in close contact, and formation is fully sealed.The gland 3 is in close contact with second sealing ring 10, is formed completely close
Envelope.
When ambient pressure acts on the elastomer 2 by the tracting pressuring hole 12, the elastomer 2 deforms upon, defeated
Go out the electric signal proportional to pressure outwards to export by the lead 7 and the outer lead 8.
By this structure design, the elastomer 2 is sealed with the pressure-inducing nozzle 1 by first sealing ring 9.It is described
Gland 3 is sealed with pressure-inducing nozzle 1 by second sealing ring 10.In this way, sensor is carrying out fatigue test, calibra tion
When technique, when occurring leaking or performance is bad, component can be convenient for changing, without sensor is integrally scrapped,
Substantially reduce production cost.
