Abstract

The utility model discloses a kind of end cover mechanism of ball valve air tightness test machine, relate to ball valve air tightness test machine field, comprise a right cylinder end cover body, a location-plate and an inflation seal ring, relatively fixing by some connecting links between location-plate and end cover body; Described end cover body circumferentially offers a groove for accommodating inflation seal ring, inflation seal ring is arranged in groove, the filling channel of inflation seal ring and exhaust passage, by drawing inside end cover body, on rear side of end cover body, are run through end cover body and are provided with an air-filled pore; Described location-plate is provided with some positioning through hole.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 are not by the ball valve air tightness test machine end cover mechanism of external force clamping.

Description

A kind of end cover mechanism of ball valve air tightness test machine

Technical field

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

Industrial tygon (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 cylinder or lifting jack 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 by cylinder clamping when ball valve two ends seal, 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 are not by the ball valve air tightness test machine end cover mechanism of external force clamping.

To achieve these goals, the utility model is by the following technical solutions: a kind of end cover mechanism of ball valve air tightness test machine, comprise a right cylinder end cover body, a location-plate and an inflation seal ring, relatively fixing by some connecting links between location-plate and end cover body; Described end cover body circumferentially offers a groove for accommodating inflation seal ring, inflation seal ring is arranged in groove, the filling channel of inflation seal ring and exhaust passage, by drawing inside end cover body, on rear side of end cover body, are run through end cover body and are provided with an air-filled pore; Described location-plate is provided with some positioning through hole.

As preferably, on front side of described end cover body, be provided with the temperature sensor that is surveyed cavity temperature in ball valve.

As preferably, described positioning through hole is bar hole.

Therefore, the utility model has following beneficial effect: (1) stretches the end cover designs of formula in adopting, ball valve end face does not stress, and improves measuring accuracy; (2) adopt inflation seal ring, when inside stretching mobile can not with wall friction in ball valve, convenient plug; (3) temperature sensor is provided with, when facilitating control and measuring, the temperature variation in ball valve.

Embodiment

Below in conjunction with accompanying drawing and specific embodiments, the utility model is further described.

A kind of end cover mechanism of ball valve air tightness test machine, see Fig. 1, Fig. 2, comprise a right cylinder end cover body 1, the thick 40mm of end cover body 1, the inflation seal ring 2 that one piece of location-plate 4 and width are 20mm, thickness is 15mm, relatively fixing by six roots of sensation connecting link 3 between location-plate 4 and end cover body 1; Described end cover body 1 circumferentially offers a groove 6 for accommodating inflation seal ring 2, groove 6 width is 20mm, the degree of depth is 15mm, inflation seal ring 2 is arranged in groove 6, the filling channel 9 of inflation seal ring 2 and exhaust passage 10 are by drawing inside end cover body 1, on rear side of end cover body 1, run through end cover body 1 and be provided with an air-filled pore 8, the existing aeration of air-filled pore 8, also can be used as bleed passage and uses; Described location-plate 4 is provided with the positioning through hole 5 of four bar shapeds, and positioning through hole 5 is positioned at four angles place of location-plate 4; The temperature sensor 7 that one is surveyed cavity temperature in ball valve 11 is provided with on front side of described end cover body 1.

During use, as shown in Figure 3, Figure 4, choose the ball valve 11 of the corresponding model of end cap, be put on test machine, both sides end cap stretches into ball valve 11 two ends, it is made to expand to inflation seal ring 2 inflation, seal ball-valve 11 inwall, forms sealed cavity, can carry out ball valve 11 air tightness test, further, temperature sensor 7 can monitor the temperature variation in cavity in real time.
