Description

A kind of ball valve sealing end cap

Technical field

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

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 polyethylene (PE) ball valve is the important control assembly of PE pipe network, requires with Compressed 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 sealing ring 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 jack simultaneously, thus sealing gasket or sealing ring and ball valve two ends are formed seal, ball valve after whole sealing is immersed in the water, then passes into Compressed 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 equipment, and the installation of ball valve also comparatively bothers, 2, adopt jack to press down pressing plate thus ball valve is sealed and sealing ring 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 can not by the ball valve sealing end cap of clamping distortion.

To achieve these goals, the utility model by the following technical solutions: a kind of ball valve sealing end cap, comprises a cylinder end cover body, a location-plate and an inflation seal ring, relatively fixing by some connecting rods 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 and a bleeder port; One piece of limiting plate is also fixed with, limiting plate and end cover body keeping parallelism between described end cover body and location-plate; 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 variations in temperature in ball valve; (4) be provided with limiting plate, end cap insertion depth can be controlled, and after ensureing that end cap insertion puts in place, end cap front end does not drop.

Accompanying drawing explanation

Fig. 1 is the structural representation of end cover mechanism.

Fig. 2 is the sectional view of end cover mechanism.

Fig. 3 is the structural representation of end cover mechanism using state.

1: end cover body; 2: inflation seal ring; 3: connecting rod; 4: location-plate; 5: positioning through hole; 6: groove; 7: temperature sensor; 8: air-filled pore; 9: bleeder port; 10: limiting plate; 11: filling channel; 12: exhaust passage; 13: ball valve.

Detailed description of the invention

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

A kind of ball valve sealing end cap, see Fig. 1, Fig. 2, comprise a cylinder end cover body 1, the thick 40mm of end cover body 1, one piece of location-plate 4 and width be 20mm, inflation seal ring 2 that thickness is 15mm, relatively fixing by six roots of sensation connecting rod 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 11 of inflation seal ring 2 and exhaust passage 12 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 and a bleeder port 9, during for testing, to inflating in ball valve 13 and losing heart; One piece of limiting plate 10 is also fixed with between described end cover body 1 and location-plate 4, limiting plate 10 and end cover body 1 keeping parallelism, limiting plate 10 can control end cap insertion depth, and after end cap inserts and put in place, limiting plate 10 withstands on ball valve end face, can ensure that end cap front end does not drop; 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 13 is provided with on front side of described end cover body 1.

During use, as shown in Figure 3, the ball valve 13 of the corresponding model of end cap is chosen, be put on test machine, both sides end cap stretches into ball valve 13 two ends, top to limiting plate 10 and ball valve 13 end face, because the driving force of end cap movement need not be very large, so limiting plate 10 pairs of ball valves 13 can not cause extrusion damage; Make it expand to inflation seal ring 2 inflation, seal ball-valve 13 inwall, forms sealed cavity, can carry out ball valve 13 air tightness test, and temperature sensor 7 can monitor the variations in temperature in cavity in real time again.
