Abstract
The invention discloses an air tightness detecting device for pressure regulators, comprising an air supplier, a standard pressure regulator and a to-be-detected regulator, wherein the air outlet of the air supplier is communicated with the standard pressure regulator and the to-be-detected regulator respectively by a first solenoid valve; a second solenoid valve and a pressure difference measuring meter are respectively connected between the standard pressure regulator and the to-be-detected regulator. The air tightness detecting device resolves the problem of low detection efficiency and poor reliability of the pressure regulators in the prior art and realizes automatic measurement to improve the measurement efficiency by measuring the pressure difference between the to-be-detected regulator and the standard pressure regulator by equal pressure method and judging whether a pressure regulating valve is within the qualified range according to the pressure difference value. Meantime, the measurement reliability is ensured.
Description
Technical field
The present invention relates to a kind of pressure regulator air-tightness detection device, belonged to the pressure regulator technical field.
Background technology
