Further, be provided with a pair of pressing plate for the chucking valve on described upper jig plate.
For guaranteeing the impermeability between frock and valve, the end cover that described rotating shaft is positioned at jig plate has fixing edge cover, and fixedly edge puts and is provided with sealing gasket.
For guaranteeing the impermeability of frock, be respectively arranged with O-ring seal between described rotating shaft and lower press plate, upper jig plate.
Be to increase 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 is connected with cylinder, drives the pressing plate motion by cylinder moving valve is compressed.
For convenience of operation, described spanner comprises and is fixed on the rotating plate in rotating shaft and is distributed in the grip structure that the circumferential prescription of rotating plate just operates.
Beneficial effect of the present invention: drive the rotating shaft campaign by rotating spanner, rotate thereby drive valve bushing, the pressure of control valve makes valve satisfy the impermeability requirement, and regulative mode is simple, and performance accuracy is high.Described pressing plate can well be fixed on valve on upper pressing plate.Described fixedly edge cover, sealing gasket, O-ring seal can guarantee the impermeability of frock and the sealing of frock and valve cooperation, guarantee that test data is accurate.Described stage clip has further strengthened the snap-in force of frock to valve.Described spanner structure handled easily can accurately be controlled the rotation of rotating shaft, the control valve impermeability.
Below in conjunction with drawings and Examples, the present invention is described in further detail.
