Specific embodiment
The utility model embodiment is described further with reference to the accompanying drawing:
As shown, the device for valve pressure testing that a kind of Quick-clamped unclamps, including rack 1, suppresses blind plate 2, compresses
Mechanism.
The blind plate 2 of suppressing is lain in a horizontal plane in rack 1, when pressure testing, can directly be placed valve 9 to be tested
On suppressing blind plate 2, sealing is then compressed by hold-down mechanism from top to bottom, 2 center of blind plate of suppressing is equipped with passing through
Pipeline is tested, after valve 9 is compacted sealing, compressed air can enter valve by testing pipeline, to realize pressure seal
Test.Wherein, the specific structure for suppressing blind plate 2 is existing design, therefore is not described herein.
As shown, the hold-down mechanism includes power source 4, elastic telescopic connector 5, intermediate connecting rod 6, the curved arm of force 7, top
Press component 8.
The power source 4 uses hydraulic cylinder, including cylinder body 41, piston rod 42, the cylinder body 41 to be hinged in rack 1, leads to
Hydraulic drive piston bar 42 is crossed along the reciprocating action of cylinder body 41, to compress and release provides driving force.Certainly, power source can also be adopted
With cylinder, since hydraulic cylinder is small in size, driving force is stronger, therefore usually preferentially selects hydraulic cylinder as power source.
The elastic telescopic connector 5 includes lower connecting rod 51, upper connecting rod 52, elastic component, on the lower connecting rod 51
End is fixed with disc spring cylinder 511, and 511 upper end of disc spring cylinder is fixedly installed with guide sleeve 512；The upper connecting rod 52 passes through guiding

For disc spring 53, the disc spring 53 is arranged in disc spring cylinder 511 and is set on upper connecting rod 52, the upper and lower ends of the disc spring 53
It offsets respectively with 512 lower end surface of guide sleeve, positive stop lug boss 521, the disc spring 53 drives lower connecting rod 51, upper connecting rod 52 opposite
Stress.
The lower connecting rod 51 is hinged in rack 1, and its lower end and 42 end of piston rod are hinged, the upper connecting rod 52
Hinged with the upper end of intermediate connecting rod 6, the lower end of the intermediate connecting rod 6 and the middle part of the curved arm of force 7 are hinged, described curved 7 one end of the arm of force
It is hinged in rack 1, installation press component 8 below the other end, the press component 8 can act with the curved arm of force 7, have and compress
The first position of valve 9 and the second position isolated with valve 9 can be realized by the kind of drive of double leval jib to valve
Quick-clamped and release, while when the press component 8 is located at first position, the elastic telescopic connector 5 was put extremely
Point certain angle.
In compressing valve event, piston rod 42 acts and elastic telescopic connector 5 is driven to swing, at this point, 53 meeting of disc spring
It is compressed, while elastic telescopic connector 5 can drive the curved arm of force 7 to swing by intermediate connecting rod 6, the curved arm of force 7 can then drive press
8 synchronization action of component.
Before dead-centre position, the elastic force that the compression of disc spring 53 generates can be driven curved by upper connecting rod 52, intermediate connecting rod 6
The arm of force 7 resets upwards, and has once crossed dead-centre position, and Impact direction will change, the elastic force that the compression of disc spring 53 generates
The curved arm of force 7 is driven downwards by upper connecting rod 52, intermediate connecting rod 6, therefore, when press component 8 is located at first position, disc spring
The elastic force that 53 compressions generate passes to the curved arm of force 7, drives press component 8 that can firmly compress valve 9, ensures that compression
Effect guarantees the reliability of airtight pressure testing.
Wherein, as the hinge joint P2 of lower connecting rod 51 and the hinge joint P1 of rack 1, intermediate connecting rod 6 and the curved arm of force 7, upper company
It is dead-centre position when the hinge joint P3 of extension bar 52 and intermediate connecting rod 6 is on the same line.
In unclamping valve event, 42 homing action of piston rod, piston rod 42 drives elastic telescopic connector 5 to swing, when
After having crossed dead-centre position, the elastic force that the compression of disc spring 53 generates is released, and cooperation piston rod 42 realizes quick release.
As shown, the rack 1 includes two side plates 11 disposed in parallel, two side plates 11 are connected by plate muscle 12
It connects, simple and stable structure, manufacture easy to produce.Meanwhile the power source 4 is arranged at two sides with elastic telescopic connector 5
Between plate 11；The intermediate connecting rod 6 is equipped with two groups with the curved arm of force 7, and is symmetricly set on two side plates 11, rationally distributed,
Stress balance is stablized, the reliability of guarantee test.
As shown, the upper end of the upper connecting rod 52 is additionally provided with movable block 522, positioning sleeve 523, operation handwheel 524, institute
It states movable block 522 to be set on interconnecting piece 52, and hinged with two groups of intermediate connecting rods 6；The positioning sleeve 523 and operation handwheel
524 are threadedly engaged with upper connecting rod 52, and the movable block 522 is located between positioning sleeve 523 and operation handwheel 524, with positioning
Set 523 and operation 524 axial limiting of handwheel cooperation.
By the adjusting to positioning sleeve 523 and operation handwheel 524, it is axial along upper connecting rod 52 to can be realized movable block 522
Position is adjusted, and is adjusted, can be finely adjusted, further expansion according to specific test requirements document to the elastic force of disc spring 53 to realize
Its scope of application.
As shown, the press component 8 includes connecting plate 81, adjusting block 82, mandril 83；The fixed peace of the connecting plate 81
Elongated mounting groove 811 is formed on the curved arm of force 7, and on the connecting plate 81, the adjusting block 82 is mounted on mounting groove
In 811, the mandril 83 is mounted on adjusting block 82.
The adjusting block 82 can be cooperated by bolt and mounting groove 811, can carry out horizontal position by mounting groove 811
Adjusting, be connected through a screw thread between the top and adjusting block 82 of the mandril 83, replacement or the top of mandril 83 may be implemented
The adjusting of 83 height and position of bar enables press component 8 according to the different size of valve, finds suitable compression point.
Wherein, two adjusting blocks 82 and mandril 83 are respectively set in every group of press component 8, and two groups of difference are arranged in press component 8
Cooperate with two groups of curved arm of forces 7, to form 4 compressions points, it is ensured that valve 9 is in compression, stress balance, guarantee test it is reliable
Property.
Further, the connecting plate 81 of two groups of press components 8 can be combined into one structure, also simultaneously by two groups of curved power
Arm 7 links into an integrated entity, so that the consistency of movement is more preferable.
In addition, piston rod 42 is withdrawn when compressing valve, when unclamping valve, piston rod stretches out, when described press component 8
