Abstract
The utility model belongs to a differential pressure control instrument technical field, in particular relates to an oblique differential pressure gauge which can be utilized on various devices for monitoring changing process of differential pressure. The utility model resolves the problems that the existing differential pressure transducers have the defects of expensive price, complex structure, and inconvenient maintenance, and the exiting U-shaped pressure gauges have the defects of low accuracy and large read error. The utility model provides the oblique differential pressure gauge which has the advantages of intuitionistic and easy off-scale reading, high accuracy, low price, and convenient maintenance, and can be widely used on various devices for monitoring changing process of differential pressure. The differential pressure gauge comprises a shell, a high-pressure side interface, a knob of a liquid feeding opening, a low-pressure side interface, and an L-shaped measuring tube. A horizontal air level and an adjusting knob are arranged on the shell, the L-shaped measuring tube is fixed on the panel of the shell, and a pressure scale is arranged on the panel. The lower section of the L-shaped measuring tube is obliquely arranged, and the upper section of the L-shaped measuring tube is vertically arranged.
Description
Technical field
The utility model belongs to minute-pressure difference control instrument technical field, particularly a kind of tilting pressure difference meter that can be widely used on the various device its pressure reduction change procedure being realized monitoring.
Background technology
Existing being used for to 0～1000P
aMinute-pressure difference in the scope realizes that the instrument of control and monitoring mainly contains minute-pressure difference transmitter and U-shaped pressure gauge, the former costs an arm and a leg, complex structure, maintenance inconvenience, though the latter is cheap, precision is lower, reading error is big, and can not satisfy some equipment ultralow minute-pressure is differed from 0～80P
aControl requirement in the scope.
Summary of the invention
The utility model at existing minute-pressure difference transmitter existingly cost an arm and a leg, the weak point of complex structure, maintenance inconvenience, simultaneously lower at the existing precision of existing U-shaped pressure gauge, the weak point that reading error is big, provide a kind of reading readability directly perceived, the precision height, cheap, easy to maintenance, can be widely used in the tilting pressure difference meter of on the various device its pressure reduction change procedure realization being monitored.
The technical solution adopted in the utility model is finished in the following way: the tilting pressure difference meter comprises housing, high-pressure side interface, liquid injection port knob, low pressure end interface and L shaped measuring tube.High-pressure side interface and low pressure end interface are located at the top of housing respectively, the liquid injection port knob is located on the liquid injection port of housing, on housing, be provided with horizontal levelling bubble and zeroing knob, L shaped measuring tube is fixed on the panel of housing, on the one or both sides of L shaped measuring tube, be provided with pressure scale, wherein, the hypomere of L shaped measuring tube partly is the tilting setting, and the epimere of L shaped measuring tube partly is vertical the setting.During use, high-pressure side interface on the tilting pressure difference meter is popped one's head in the high-pressure side on the equipment that its pressure reduction change procedure is realized monitoring and is joined, and the low pressure end interface on the tilting pressure difference meter is popped one's head in the low pressure end on the equipment of its pressure reduction change procedure being realized monitoring and joined.
The utility model is compared with existing minute-pressure difference transmitter, have simple in structure, cheap, the characteristics of easy maintenance; Compare with existing U-shaped pressure gauge, have reading readability directly perceived, the characteristics that precision is high.The utility model is particularly suitable as the pressure difference meter to its pressure reduction change procedure realization monitoring on the equipment such as air-conditioning, purification, cleaning.
