Efficiency.
To achieve the above object, the technical solution of the utility model is：
A kind of safety valve testing platform, including cylindrical base, several clamping jaws (1), chuck (2), seal washer (3) and top
Tight device (4), the chuck (2) are arranged on outside the cylindrical base, are provided with the chuck (2) and the clamping jaw (1) number
Identical loose slot is measured, the clamping jaw (1) is arranged in the loose slot, and pick-and-place action, institute can be done in the loose slot
State seal washer (3) to be arranged at the top of the cylindrical base, be used to place flange form safety valve above, the safety valve testing is put down
Platform also includes U-shaped voussoir (5), gangbar (6) and joystick (7), and groove (11), the U have been issued in clamping jaw (1) both sides
The both sides of type voussoir (5) are fastened in the groove (11), and can be movable along the groove (11), the cylindrical base
The outer activity external member being arranged with relative to cylindrical base axial rotation, the gangbar (6) include and the clamping jaw (1) quantity phase
Same connecting rod, each described connecting rod one end are connected with the clamping jaw (1), and the other end is connected with the activity external member, the control
Handle (7) is connected with the activity external member, by joystick (7) while adjusts the amplitude that moves forward and backward of clamping jaw, the top
Tight device (4) is arranged on above the seal washer (3), mobilizable flange to being positioned on the seal washer (3)
Formula safety valve implements upper-lower compacting and loosens work.
Further, the holding device (4) uses hydraulic pressure holding device or air pressure holding device.
Further, ball is provided between the cylindrical base and the activity external member, realizes both by ball
Relatively rotate.
The beneficial effects of the utility model are：Both sides are slotted on existing clamping jaw, design U-shaped voussoir, can be according to verification
The requirement of safety valve model and specification adjusts U-shaped voussoir to control the range of clamping jaw and thickness, is met by this combination clamping jaw
Existing domestic and international all flange form safety valve testing requirements, while gangbar is installed on clamping jaw, with the same time control of joystick
The distance that multiple clamping jaws move forward and backward is made, reduces safety valve testing labor intensity, improves safety valve testing efficiency.

Embodiment
Design, concrete structure and caused technique effect of the present utility model are carried out below with reference to embodiment and accompanying drawing
Clearly and completely describe, to be completely understood by the purpose of this utility model, feature and effect.Obviously, described embodiment
It is part of the embodiment of the present utility model, rather than whole embodiments, based on embodiment of the present utility model, the skill of this area
The other embodiment that art personnel are obtained on the premise of not paying creative work, belong to the model of the utility model protection
Enclose.
As shown in figure 1, a kind of safety valve testing platform, including cylindrical base, 3 clamping jaws 1, chuck 2, the and of seal washer 3
Hydraulic pressure or air pressure holding device 4, the chuck 2 are arranged on outside the cylindrical base, and 3 loose slots are provided with the chuck 2,
The clamping jaw 1 is arranged in the loose slot, and pick-and-place action can be done in the loose slot, and the seal washer 3 is arranged on
