Abstract
The utility model provides a pressure device used for the verification of a pressure instrument, and the pressure device is characterized in that a precession wobble pump and a pressure fine regulating device are adopted as pressure-making parts; an outlet of the precession wobble pump is communicated with the pressure fine regulating device and the pressure instrument through a stop valve. The utility model can not only placidly add pressure and decrease pressure, but also precisely regulate pressure and keep stability of the pressure.
Description
The utility model relates to a kind of pressue device that is used for the manometer verification, particularly a kind ofly can pressurize reposefully, step-down, and the stable pressue device that can keep-up pressure.
By the vertification regulation of manometer as can be known, the pressue device that is used for the manometer verification should be able to pressurize reposefully, step-down, and can on the calibrating point, keep-up pressure stable.And the pressue device that is used for the manometer verification at present all can not satisfy this requirement well.
The purpose of this utility model be to provide a kind of and can pressurize reposefully, step-down, and the stable pressue device that can keep-up pressure is to satisfy the verification requirement of manometer.
The utility model is achieved in that and adopts screw type wobble pump and the conduct of pressure micromatic setting to make pressure part, and hand delivery side of pump is connected with pressure micromatic setting and manometer by stop valve.Earlier pressurize for manometer gently,, close stop valve, with the pressure micromatic setting pressure is accurately adjusted on the force value of calibrating again when pressure during near the force value of calibrating point with wobble pump.
The utility model because adopt the screw type wobble pump and the pressure micromatic setting as making pressure part, and hand delivery side of pump is connected with pressure micromatic setting and manometer by stop valve.So not only can pressurize reposefully, step-down, and can accurately adjust pressure, what keep-up pressure is stable.
Below in conjunction with accompanying drawing principle of work of the present utility model is done to describe in detail.
Accompanying drawing is a fundamental diagram of the present utility model.
With reference to accompanying drawing, earlier stop valve [3], [5] are opened, screw out wobble pump screw rod [1], the fluid in the lubricating cup [4] is entered in the plunger shaft of shaking pump [2].Then, close stop valve [3], wobble pump screw rod [1] is screwed in, the fluid in the wobble pump plunger shaft [2] is pressed in manometer [7] and [8] by stop valve [5], is its pressurization.When pressure during near the force value of calibrating point, close stop valve [5], with pressure micromatic setting [6] pressure is accurately adjusted on the force value of calibrating, manometer is carried out verification.
