Summary of the invention
The object of this invention is to provide a kind of valve air-leakage test adjusting tool, solving the adjustment of existing valve air-leakage test needs manual wrench to regulate, and degree of regulation is low, the problem of inconvenient operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of valve air-leakage test adjusting tool, comprise the upper jig plate for supporting valve body, lower press plate, described upper jig plate is provided with the upper jig plate gas outlet and upper jig plate air intake opening that coordinate with valve body air intake opening, valve body gas outlet respectively, upper jig plate air intake opening is connected with the gas outlet, side being arranged on upper jig plate side; Lower press plate is provided with lower press plate air intake opening, is provided with the rotating shaft of hollow between upper jig plate gas outlet and lower press plate, lower press plate air intake opening is connected conducting by the pipeline of lower press plate inside with rotating shaft; Described rotating shaft is fixedly installed the spanner driving axis of rotation, described rotating shaft port coordinates stuck with the lining on valve body, and lining transfer axle is rotated together.
Further, described upper jig plate is provided with a pair for clamping the pressing plate of valve body.
For ensureing the impermeability between frock and valve, one end cover that described rotating shaft is positioned at jig plate has fixing bushing, fixing bushing on be provided with sealing gasket.
For ensureing the impermeability of frock, between described rotating shaft and lower press plate, upper jig plate, be respectively arranged with O-ring seal.
For increasing the snap-in force between rotating shaft and valve, described rotating shaft is positioned between the end of lower press plate and lower press plate and is provided with stage clip.
Preferably, described pressing plate one end and cylinders, drive pressing plate motion to compress valve body by cylinder moving.
For convenience of operation, described spanner comprises the grip structure of the rotating plate be fixed in rotating shaft and the one group of handled easily being distributed in rotating plate circumference.
Beneficial effect of the present invention: drive pivot by rotating spanner, thus drive valve bushing to rotate, the pressure of control valve, makes valve meet impermeability requirement, and regulative mode is simple, and performance accuracy is high.Valve can well be fixed on upper pressing plate by described pressing plate.Described fixing bushing, sealing gasket, O-ring seal can ensure the impermeability of frock and the sealing of frock and valve cooperation, ensure that test data is accurate.Described stage clip further enhancing the snap-in force of frock to valve.Described spanner structure handled easily, accurately can control the rotation of rotating shaft, control valve impermeability.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
