Abstract

The utility model discloses a kind of ball valve air tightness test machine, comprise one " recessed " font frame, described frame recess is provided with the bracing frame of ball valve, the frame of bracing frame both sides is provided with a pair end cover relatively, 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 ball valve is inconvenient, the problem of the easy deformation effect measuring accuracy of ball valve in order to solve for the utility model, and propose a kind of easy to operate, structure is simple, and ball valve two ends can not by the ball valve air tightness test machine of clamping distortion.

Description

Ball valve air tightness test machine

Technical field

The utility model relates to air tightness test machine field, particularly relates to a kind of ball valve air tightness test machine.

Background technology

Ball valve makes opening and closing element with the spheroid of band manhole, and spheroid rotates with valve rod, to realize the valve of switching motion.Ball valve is mainly used as cut-out, distributes and change the flow direction of medium, all needs to carry out sealing propertytest, not so have larger potential safety hazard in use procedure before dispatching from the factory.

Industrial polythene PE ball valve is the important control assembly of PE pipe network, requires with pressure gas to be that medium carries out experiments of sealing performance before therefore using.When prior art is tested ball valve, usual employing sealing gasket or O-ring seal are placed in the outside at ball valve two ends, be clamped in ball valve two ends with the force application apparatus such as lifting jack or hydraulic cylinder simultaneously, thus sealing gasket or O-ring seal and ball valve two ends are formed seal, ball valve after whole sealing is immersed in the water, then passes into pressure gas toward ball valve inside 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 ball valve also comparatively bothers, 2, adopt lifting jack to press down pressing plate thus ball valve is sealed and O-ring seal to be placed in ball valve two ends outside, and with hydraulic cylinder be clamped in ball 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 ball 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, ball valve can be made to deform, cause the out-of-flatness of ball valve end face, thus make cannot form sealing between ball valve and pressing plate, bring qualitative erroneous judgement, in addition, the words that the power pressing down or clamp is excessive, also directly ball valve can be damaged.

Summary of the invention

The clamping of current ball valve is inconvenient, the problem of the easy deformation effect measuring accuracy of ball valve in order to solve for the utility model, and propose a kind of easy to operate, structure is simple, and ball valve two ends can not by the ball valve air tightness test machine of clamping distortion.

To achieve these goals, the utility model is by the following technical solutions: ball valve air tightness test machine, comprise one " recessed " font frame, described frame recess is provided with the bracing frame of ball valve, the frame of bracing frame both sides is provided with a pair end cover relatively, 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 bracing frame upper surface both sides are respectively provided with a ball valve supporting seat, V-shaped structure or U-shaped structure on the upside of ball valve supporting seat.

As preferably, be bolted between described ball valve supporting seat and bracing frame, ball valve supporting seat both sides are respectively provided with a through hole, and bracing frame is provided with some groups with through hole on ball valve supporting seat to the threaded hole being applied to fixing ball valve supporting seat.

As preferably, described ball valve supporting seat V-structure or the relative inner edge of U-shaped structure are provided with fillet.

As preferably, on the upside of described driving mechanism, be provided with dust cover.

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 ball valve supporting seats, spacing is adjustable, is applicable to the ball valve of different model, compatible good.
