Abstract
The utility model relates to a new structure of a transmitting element on a pressure sensor, made of elastic steel alloys and provided with a plurality of uniformly distributed notches. According to the corresponding dimension needed by the matched pressure sensor, the size of transferred pressure and claimed accuracy by instruments, users select the thickness of integral valve sheets and notch number. Compared with the decomposition sheet manufacture in the prior art, the utility model which has simple manufacture, convenient maintenance and assembling, can improve measuring range and raise measurement precision.
Description
The utility model is the new construction of transmitting element on the pressure transducer.
At (HAENNI) peak pressure meter (measurement range 40-180kg/cm of Switzerland " Han Na "
2, precision ± 2%) and in the prior art, its transmitting element is shown in accompanying drawing three, four, the eight lobes decomposition sheet (6) that transmission pressure is used at metallic membrane (1) upper support, this decomposes sheet (6) complex structure, not only processing difficulties, and assembling and overhaul extremely inconvenient.
The purpose of this utility model is the global section diaphragm (2) (seeing accompanying drawing one, two) that adopts a kind of elastic alloy steel to make, it will be according to the different size and the purposes of instrument, the centre has mounting hole and some equally distributed notches, so both guaranteed the transmission performance of force-summing element, improved the serviceable life of the circular iris (1) that directly contacts with the pulsed combustion gas again, and also improve and simplified processing technology, make the overall package debugging simple, open and inspect easy to maintenance.
Principle of work of the present utility model (shown in accompanying drawing one, two): global section diaphragm (2) adopts the elastic alloy steel, and open some equally distributed notches (5) therebetween, according to the required corresponding size of the pressure transducer that is equipped with, transmit the size of pressure and measurement range and the precision that instrument requires, select the thickness (range of choice can between 0.3～1.2mm) of global section diaphragm (2) and selection notch number (range of choice can at 4～10), in the measurement component (4) that the pulsed gaseous-pressure is delivered to instrument.
This global section diaphragm (2) is compared with the decomposition sheet (6) of prior art, and its advantage is that the global section diaphragm is an one-piece construction, and processing technology is simple, and notch is evenly distributed, and the diaphragm good springiness guarantees the transmission performance of force-summing element and the measuring accuracy of instrument.

Annex two global section diaphragms
Accompanying drawing three Switzerland " Han Na " peak pressure meter structural principle
Accompanying drawing four decomposes sheet
An embodiment of the present utility model (shown in accompanying drawing one, two) is for being used for the surveying instrument of diesel engine explosion pressure, and its pressure limit is 20～150kg/cm
2, precision ± 1.5% is compared with the Switzerland product, has reduced initial reading, can measure the compression pressure of locomotive cylinder of diesel engine.Global section diaphragm (2) has improved the transmission characteristic and the force-bearing situation of the circular iris (1) that directly bears the cylinder gaseous-pressure.Arrow is depicted as cylinder gaseous-pressure direction of transfer in the accompanying drawing, and gaseous-pressure is converted to concentrated force through circular iris (1) and supporting global section diaphragm (2) thereon, passes to measurement component (4) by force-summing element (3) again, to demonstrate the force value of measurement.
Global section diaphragm (2) is that elastic alloy steel (as 3J21-Co40NiCrMo) thickness 0.40mm(such as pressure limit are at 30～180kg/cm
2The time, also can select 0.8mm for use), the centre has circular hole, is used for installing, and has eight notches (6) that even distribution groove width is 1mm around circular hole, (as pressure limit at 30～180kg/cm
2The time notch can open six) guarantee that the stress of diaphragm evenly distributes, prolonging its serviceable life, and make gaseous-pressure---the transfer linearityization of concentrated force reduces initial reading, thereby has improved the measurement range of surveying instrument.Use by in-site measurement, easy to operate, stable reading, utilization is reliable, and the accuracy height is easy to open and inspect and keep in repair simultaneously.
Compared with the prior art:
1. the global section diaphragm is easy to processing, can guarantee precision;
2. global section diaphragm complete machine is assembled, opens and inspect simple and easy, convenient;
3. the global section diaphragm is used for diesel engine explosion pressure measuring instrument, makes the apparatus measures scope more reasonable, can satisfy the needs that diesel engine of locomotive is measured compression pressure without combustion and explosion pressure simultaneously.
Claims (1)
1, diesel engine explosion pressure measuring instrument is made by the elastic alloy steel with global section diaphragm (2), and feature of the present utility model is: have 4～10 equally distributed notches (6) around global section diaphragm (2) center mounting hole of 0.3～1.2mm thickness.
