Valve is the open-close on-off in a kind of gas circuit or water route, is mainly used as cut-out, distributes and change the flow direction of medium, all need to carry out sealing propertytest, not so have larger potential safety hazard in use procedure before dispatching from the factory.
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
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 diffusion valve test device for air tightness of clamping distortion.
To achieve these goals, the utility model by the following technical solutions: a kind of diffusion valve test device for air tightness, comprises a frame, is provided with the fixed mechanism of diffusion valve on front side of described frame, is provided with the sealing mechanism of diffusion valve inside frame; Described fixed mechanism comprises a positioning block, a fixture block, a screw mandrel and a handwheel, a pilot hole is provided with in the middle of described locating piece, fixture block is located in pilot hole, can move up and down, be connected with handwheel by screw mandrel on the upside of fixture block, threaded engagement between screw mandrel and locating piece, is provided with rotation relocation mechanism between fixture block and screw mandrel; Described sealing mechanism comprises a cylinder and a gland bonnet, described gland bonnet is fixed on front side of the piston rod of described cylinder, cylinder body and the frame of cylinder are fixed, sealing gasket is provided with on front side of gland bonnet, filling block is provided with on front side of sealing gasket, filling block afterbody is threaded with gland bonnet through sealing gasket, filling block offers test pore, is provided with test air vent channel between filling block and gland bonnet.
As preferably, the test air vent openings on described filling block down.
As preferably, described rotation relocation mechanism is be provided with a spheroid on the downside of screw mandrel, offer on the upside of fixture block one with the counterbore of described spheroid clamping.
As preferably, on the downside of described fixture block He on the downside of pilot hole, be provided with the clamping cambered surface of mating with diffusion valve.
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; 3, reduce test cavity, test more accurate.
