The anti freezing solution choosing of injecting a kind of inner closed cavity of radial corrugated tube diaphragm anti-freeze pressure meter of dial scale band fluorescent indication has liquid or the amorphous material of the low freezing point that is lower than tensimeter environment for use temperature.
Be coated in phosphor powder on tensimeter pressure scale display disc that the tensimeter index dial scribbles pressure sign and the gauge hand surface scribbles phosphor powder, so that tensimeter pressure scale display disc and gauge hand have had fluorescent indicating effect at night.
When will this manometric lower sub being installed on the water pipeline with pressure and since the pressure in the water pipeline with the water in the pipeline by tensimeter impulse interface be pressed on the pressure gauge sensing membrane portions around the corrugated tube in the character cut in bas-relief mouth, hydraulic pressure cause corrugated tube deformation after, the pressure of water passes to pressure sensing barrier film, pressure sensing barrier film by the anti freezing solution in the corrugated tube and produces deformation and pressure conduction to pressure gage spring tube, the pointer that scribbles phosphor powder by tensimeter amplifier and tool again indicated force value at the pressure scale display disc that tool scribbles phosphor powder.
The tensimeter pressure sensor is chosen the corrugated tube with scalability, when the water freezing in the gap around the corrugated tube, causes corrugated tube to produce deformation, and the deformation of corrugated tube does not affect the pressure conduction performance of corrugated tube.
Beneficial effect of the present invention is: a kind of radial corrugated tube diaphragm anti-freeze pressure meter that 1, is installed on the water pipeline can prevent that water under high pressure from entering pressure gage spring tube inner chamber, tensimeter body impulse straight length inner chamber, makes tensimeter build-up of pressure table bourdon tube compressive deformation table when the environment for use temperature is low can not refer to zero or cause the pressure gage spring tube accidents caused phenomenon of breaking.2, can prevent from having corrosive liquids or gas and enter the bourdon tube inner chamber of tensimeter weakness and cause the corrosion of copper bourdon tube, prolong pressure gage spring tube serviceable life.3, can be so that tensimeter has the function of fluorescent indicated pressure at night.
