The another side central hole location of flange 3, the other end and pressure transmitter 1 are welded to connect.Meanwhile the inner hole and flange of capillary 2
The conducting of 3 centre bores.
It surveys between pressure pedestal 10, connecting rod 4, flange 3, capillary 2 and pressure transmitter 1 and forms a sealing pilot
Cavity, and the silicone oil 9 charged in transit chamber body is, it can be achieved that pressure is transmitted.Specifically, the isolation diaphragm at pressure 10 both ends of pedestal is surveyed
The intracorporal silicone oil 9 of the pressure transit chamber detected carries out pressure transmitting to pressure transmitter 1.
Similarly, in the teletransmission pressure transmitter of the present exemplary embodiment, the measurement isolation diaphragm at teletransmission end is by routine
One diaphragm becomes two diaphragms, under identical flange caliber size, realizes the measuring diaphragm of teletransmission pressure transmitter
Area increases, and is advantageous for improving the performance of instrument in this way.
Fig. 2A shows the structural schematic diagram of the teletransmission pressure transmitter of the second exemplary embodiment according to the present invention.
As shown in Figure 2 A, the teletransmission pressure transmitter includes teletransmission component and the pressure transmitter connecting with teletransmission component 1, wherein
The teletransmission component includes surveying pressure pedestal 10, the first opposite isolation diaphragm 7 and the second isolation diaphragm 8, conduit 5,3 and of flange
Capillary 6.
Preferably, surveying pressure pedestal 10 is that there is the cylindrical of three through-hole of pilot to survey pressure pedestal.First isolation diaphragm 7 and
Two isolation diaphragms 8 are respectively welded in the cylindrical both ends of the surface for surveying pressure pedestal 10.One end of conduit 5 is welded on survey pressure pedestal 10
Outer circumference surface on, the other end is inserted in 3 sealing surface center of flange, and welds and play a supporting role.
Capillary 6 is preferably soft state stainless steel capillary.Conduit 5 and flange 3 are successively inserted in outside capillary 6.Capillary
The excircle hole of 6 one end insertion pedestal 10 is simultaneously fixedly connected with the pedestal 10, and the other end of capillary 6 passes through in flange 3
Heart hole and extend be connected to pressure transmitter 1, preferably fixed by welded seal.Pressure pedestal 10, capillary 6 and pressure is surveyed to become
It send and forms a sealing pilot cavity between device 1, and the silicone oil 9 charged in transit chamber body is, it can be achieved that pressure is transmitted.Specifically
Ground is surveyed the intracorporal silicone oil 9 of pressure transit chamber for pressing the isolation diaphragm at 10 both ends of pedestal to detect and is pressed to pressure transmitter 1
Power transmitting.
It follows that the measurement isolation diaphragm at teletransmission end is by routine in the teletransmission pressure transmitter of the present exemplary embodiment
A diaphragm become two diaphragms, under identical flange caliber size, realize the measuring diaphragm of teletransmission pressure transmitter
Area increase, be advantageous in this way improve instrument performance.
In the technical solution of two examples above embodiment, surveys connection type and pressure between pressure pedestal and flange and pass
Path difference is passed, but pressure is passed to pressure transmitter ontology by the silicone oil that isolation diaphragm can charge in transit chamber body.Instrument
The measurement isolation diaphragm at table teletransmission end becomes realizing teletransmission under two, then identical flange caliber size from conventional one
The area of the measuring diaphragm of pressure transmitter increases, and is advantageous for improving the performance of instrument in this way.
Fig. 3 A and Fig. 3 D are that the teletransmission pressure transmitter of the invention and existing teletransmission pressure by taking DN40 flange as an example become

Row compares.Companion flange bore is about 45mm.Under identical flange caliber size, instrument of the present invention is using survey pressure pedestal 10
First isolation diaphragm 7 and the second isolation diaphragm 8 at both ends measure, and two isolation diaphragm effective diameters can achieve
35mm, and conventional instrument is measured using the isolation diaphragm 11 that flange sealing surface end is welded, effective diameter is
38mm.Thus compare, it can be seen that survey pressure 10 both ends of pedestal isolation diaphragm the gross area than a diaphragm area greatly very
It is more.Make the effective area for increasing isolation diaphragm in this way, can reduce mambrane tension, increases membrane flexive deflection, it is sufficient to support
Disappear the pressure for being influenced by temperature and silicone oil being caused to expand, and ensure that the performance of pressure transmitter.
In conclusion the teletransmission pressure transmitter design method of this double isolation diaphragms of the invention, it can be identical
Under installation space, increase the quantity of isolation diaphragm, the covert effective measurement area for increasing isolation diaphragm, can thus reduce or
Eliminate because diaphragm is small and drawback that rigidity is big.The measurement for solving small-bore flange teletransmission pressure transmitter is unstable, temperature drift is big
Quality problems.
In conjunction with the explanation and practice of the invention disclosed here, the other embodiment of the present invention is for those skilled in the art
It all will be readily apparent and understand.Illustrate and embodiment is regarded only as being exemplary, true scope of the invention and purport are equal
It is defined by the claims.
