Position-limited hoop 13 is fixed with below substrate 5, ejection hydraulic cylinder 14, the ejection hydraulic cylinder in the middle part of the lower end of auxiliary substrate 5, is fixed with
14 shaft end is fixed with 15, it is described take over a business 15 on be uniformly hinged with pressure arm 16, the pressure arm 16 be respectively positioned on position-limited hoop 13 with
Interior, pressure arm 16 can inwardly swing under the contraction of position-limited hoop 13 and be received in together, and equal activity on pressure arm 16 is cased with and slideway 10
The slide block 17 of cooperation, the slide block 17 are corresponded in recess 9, and can be slided in recess 9, the medial surface connection of slide block 17
On the upper surface of spring 12, the upper end of pressure arm 16 corresponds to respectively and is provided with for being pressed on the flange of gate valve through bar hole 4
Briquetting 18, the briquetting 18 are located above testboard 2, and work as the axle extension elongation of ejection hydraulic cylinder 14 most in short-term, pressure arm 16
In the outermost of bar hole 4, when the axle extension elongation for ejecting hydraulic cylinder 14 is most long, pressure arm 16 is located at the most inner side of bar hole 4,
When gate valve is begun place into, pressure arm 16 is moved to into the outermost of bar hole 4, to be put into gate valve, gate valve is placed on platen 7

On the left surface or right flank of bearing substrate 1, the axle of hydraulic cylinder 3 is overturn when packing up, pull testboard 2 to switch to vertically, when turning over
When turning the shaft extension of hydraulic cylinder 3 and going out, testboard 2 is pushed into into horizontal level.
The diameter of a circle that the internal diameter of the position-limited hoop 13 is surrounded jointly more than the pin joint for taking over a business 15 and pressure arm 16.
During use, first with upset hydraulic cylinder, monitor station is switched to vertically, gate valve is placed on platen using driving, so
Start ejection hydraulic cylinder afterwards, eject hydraulic cylinder axle shrink after, take over a business while shrink upwards, the internal diameter due to position-limited hoop is more than pushing up
The diameter of a circle that the pin joint of disk and pressure arm is surrounded jointly, pressure arm with take over a business shrink upwards when, got over by the pressure of position-limited hoop
Come less, pressure arm starts to open under the action of the spring, now gate valve is put on platen, afterwards by the shaft extension of ejection hydraulic cylinder
Go out, the side that now pressure arm opens gradually is taken in position-limited hoop, and briquetting is gradually tapered up together, by the flange screw of gate valve in pressure
Briquetting as the tightening process of pressure arm is to swing rather than translate, therefore is arranged to the inner and is inclined upwardly shape, works as pressure by the central authorities of disk
When block inwardly swings, the angle of oscillation of the inclination angle of briquetting gradually pressed arm is offset, the final pressure for causing to be pressed on the flange of gate valve
Block is presented and is close to horizontal impaction state, is conducive to improving the degree of stability for clamping, is started compression hydraulic cylinder, compression hydraulic cylinder afterwards
Shaft extension go out after, promote platen move upwards, move up the gate valve on platen, so as to briquetting is more tightly against lock
On the upper surface of the flange of valve lower end, it is ensured that reliable sealed environment is formed between gate valve and platen, subsequently using upset hydraulic pressure
Monitor station is gone to level by cylinder, to facilitate testing staff to observe, while being put into beneficial to detection water, is passed through in most backward annular seal space
Gas is tested.
Ultimate principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
Personnel it should be appreciated that the present invention is not restricted to the described embodiments, the simply explanation described in above-described embodiment and description this
