Abstract
The utility model discloses a kind of valve air tightness test machine, comprise one " recessed " font frame, described frame recess establishes valvular bracing frame, is provided with the elevating mechanism for adjusting support frame height on the downside of bracing frame; The frame of bracing frame both sides is provided with a pair end cover relatively, and each end cover is provided with test pore, and the frame side that the end cover of every side is corresponding is provided with the driving mechanism of corresponding end cover.The clamping of current valve is inconvenient, the problem of the easy deformation effect measuring accuracy of valve in order to solve for the utility model, and propose a kind of easy to operate, structure is simple, and valve two ends can not by the valve air tightness test machine of clamping distortion.
Description
Technical field
The utility model relates to air tightness test machine field, particularly relates to a kind of valve air tightness test machine.
Background technology
Valve be gas or liquid communication time conventional opening and closing element, for different occasion, there is different sealing requirements, therefore, all need before dispatching from the factory to carry out sealing propertytest, not so have larger potential safety hazard.
When prior art is to valves test, usual employing sealing gasket or O-ring seal are placed in the outside at valve two ends, be clamped in valve two ends with the force application apparatus such as lifting jack or hydraulic cylinder simultaneously, thus sealing gasket or O-ring seal and valve two ends are formed seal, valve after whole sealing is immersed in the water, then passes into pressure gas toward valve internal and check its sealing property.
Above-mentioned test method has following shortcoming: 1, operating process is complicated, and its frame heavier-weight, need be immersed in the water frame by external unit, and the installation of valve also comparatively bothers, 2, adopt lifting jack to press down pressing plate thus valve is sealed and O-ring seal to be placed in valve two ends outside, and with hydraulic cylinder be clamped in valve two ends seal time, the all more difficult control of dynamics of both, the words that the power pressing down or clamp is inadequate, the sealing of pressing plate and valve end may be made not firm, thus the accuracy of impact test, bring qualitative erroneous judgement, the words that the power pressing down or clamp is excessive, valve can be made to deform, cause the out-of-flatness of valve end face, thus make cannot form sealing between valve and pressing plate, bring qualitative erroneous judgement, in addition, the words that the power pressing down or clamp is excessive, also directly valve can be damaged.
Summary of the invention

To achieve these goals, the utility model is by the following technical solutions: a kind of valve air tightness test machine, comprise one " recessed " font frame, described frame recess establishes valvular bracing frame, is provided with the elevating mechanism for adjusting support frame height on the downside of bracing frame; The frame of bracing frame both sides is provided with a pair end cover relatively, and each end cover is provided with test pore, and the frame side that the end cover of every side is corresponding is provided with the driving mechanism of corresponding end cover.
As preferably, there are two large polished rods described frame both sides across erection, end cover both sides be fixed with described two large polished rods with the use of screw mandrel slide block, end cover can slide along large polished rod.
As preferably, described elevating mechanism is relative fixing with one piece of web joint on the downside of bracing frame, and web joint, by some little polished rod guide-localizations, is fixed with the screw mandrel slide block of a rhizoid bar in the middle of web joint, screw mandrel runs through web joint and vertically arranges, and is provided with the drive motor of screw mandrel bottom frame.
As preferably, described bracing frame upper surface both sides are respectively provided with a valve supporting seat, V-shaped structure on the upside of valve supporting seat.
As preferably, be bolted between described valve supporting seat and bracing frame, valve supporting seat both sides are respectively provided with a through hole, and bracing frame is provided with some groups with through hole on valve supporting seat to the threaded hole being applied to fixed valve supporting seat.
As preferably, the relative inner edge of described valve supporting seat V-structure is provided with fillet.
Therefore, the utility model has following beneficial effect: (1) clamping automatically, test, more convenient operation; (2) without entering ability of swimming test, it is more convenient to test; Between (3) two valve supporting seats, spacing is adjustable, is applicable to the valve of different model, compatible good.
