Embodiment bis-
As shown in Figure 1, the utility model embodiment provides a kind of pick-up unit, for detection of the sealing of ball valve 4, pick-up unit comprises clamping plate 1, web member 2 and seal 3, one end of web member 2 is connected with clamping plate 1, the other end of web member 2 stretches in the port of ball valve 4, seal 3 is arranged between web member 2 and ball valve 4 inwalls, on web member 2, be provided with the air admission hole 21 with ball valve 4 inner conductings, on clamping plate 1, be provided with through hole 11, air admission hole 21 and through hole 11 conductings, gas is filled with ball valve 4 inside through through hole 11, air admission hole 21 successively.
Wherein, web member 2 is set on clamping plate 1, one end of web member 2 is stretched in ball valve 4, on web member 2, be provided with air admission hole 21, these air admission hole 21 through-connections 2, clamping plate 1 is provided with through hole 11, this through hole 11 and air admission hole 21 conductings, on web member 2, be also provided with seal 3, seal 3 is the junction with ball valve 4 for seal connector 2, from those skilled in the art, detect between pipeline and air admission hole 21 and can seal by the water-tight equipment detecting on pipeline, so in testing process, detecting pipeline is connected with air admission hole 21 by through hole 11 and is filled with test gas to ball valve 4 inside, test gas can or not spill from the junction of web member 2 and ball valve 4 from air admission hole 21, and, due to the device that adopts the utility model to provide, make be connected with ball valve 4 or testing process in all can not apply axial force to ball valve 4, if therefore there is the place of failure welding on ball valve 4, in testing process, can find immediately, so can improve the accuracy that detects ball valve 4.
As shown in Figure 3, Figure 5 and Figure 6, further, the seal 3 is gas-flow closure circle 31, on web member 2, be provided with air-filled pore 22, charging connector 311 on gas-flow closure circle 31 inserts in air-filled pore 22, when gas-flow closure circle 31 is inflated, charger is from the interior insertion charging connector 311 of air-filled pore 22 and inflate to gas-flow closure circle 31.
Wherein, because the gas pouring has very high pressure, therefore, in order to increase the reliability of seal 3, be preferably gas-flow closure circle 31 in ball valve 4.Air-filled pore 22 is set on connecting pipe 24, gas-flow closure circle 31 is socketed on connecting pipe 24, and the charging connector on gas-flow closure circle 31 311 is inserted in air-filled pore 22, web member with gas-flow closure circle 31 2 is stretched into behind ball valve 4 inside, be connected with the charging connector 311 in air-filled pore 22 by charger and to the interior inflation of gas-flow closure circle 31.It should be noted that, the pressure in gas-flow closure circle 31 will, higher than the pressure that detects ball valve 4 inside when ball valve 4, so can prevent that the too high test gas that makes of ball valve 4 internal pressures from spilling from gas-flow closure circle 31.
As shown in Fig. 2, Fig. 5 and Fig. 8, further, web member 2 comprises ring flange 23 and connecting pipe 24, clamping plate 1, ring flange 23 and connecting pipe 24 are connected in turn, connecting pipe 24 stretches in ball valve 4 ports, gas-flow closure circle 31 is socketed on connecting pipe 24, and air-filled pore 22 is arranged on the tube wall of connecting pipe 24.
Wherein, ring flange 23 is fixedly connected with connecting pipe 24, and the air admission hole 21 on connecting pipe 24 runs through ring flange 23, by being set, ring flange 23 fixes being connected of connecting pipe 24 and clamping plate 1, on ring flange 23, be provided with threaded hole, between ring flange 23 and clamping plate 1, can be connected by bolt, make connecting pipe 24 more firm with being connected of clamping plate 1.Air-filled pore 22 is arranged on the tube wall of connecting pipe 24, when gas-flow closure circle 31 is socketed on connecting pipe 24, gas-flow closure circle 31 to be arranged on air-filled pore 22 before, so prevent detect time, detect gas spill from air-filled pore 22.Charging connector 311 is inserted to air-filled pore 22, connecting pipe 24 is inserted in ball valve 4.It should be noted that, web member 2 in the utility model can be the structure being connected with connecting pipe 24 by ring flange 23, also can be ring flange 23 and connecting pipe 24 is unified, overall structures, be provided with flange in connecting pipe 24 ends, be connected other end input ball valve 4 inside of connecting pipe 24 with clamping plate 1 by flange.
As shown in Figure 5 and Figure 8, further, be provided with stopper slot 25 on the outer wall of connecting pipe 24, gas-flow closure circle 31 is arranged in stopper slot 25, and this stopper slot 25 is for fixing gas-flow closure circle 31.
Wherein, stopper slot 25 is set on the outer wall of connecting pipe 24, gas-flow closure circle 31 is arranged in stopper slot 25, can fix the position of gas-flow closure circle 31 on connecting pipe 24, as preferably, stopper slot 25 is set to ring groove.And when 31 unaerated of gas-flow closure circle, the external diameter of gas-flow closure circle 31 is less than the internal diameter of ball valve 4, so can avoid connecting pipe 24 in the time stretching into ball valve 4, the friction between gas-flow closure circle 31 and ball valve 4 inwalls, the serviceable life of prolongation gas-flow closure circle 31.
As in Figure 3-5, further, air-filled pore 22 is along the radial direction setting of connecting pipe 24, and air-filled pore 22 and air admission hole 21 conductings.
Wherein, the set-up mode of air-filled pore 22 has multiple, and air-filled pore 22 can be towards the radial direction setting of connecting pipe 24, also can be towards the axial direction setting of connecting pipe 24.As preferably, air-filled pore 22 towards the radial direction setting of connecting pipe 24 and with air admission hole 21 conductings, so arrange the processing of air-filled pore 22 simply, and the impact that connecting pipe 24 is caused is also less, therefore in the time that larger ball valve 4 is detected, the air-filled pore 22 that preferably radial direction arranges.
As shown in Fig. 6-8, further, air-filled pore 22 is along the axial direction setting of connecting pipe 24, and air-filled pore 22 and through hole 11 conductings.
Wherein, when detecting compared with small ball 4, because the caliber of connecting pipe 24 also can correspondingly reduce, air-filled pore 22 is radially set and is not easy to charger and is connected with charging connector 311.Therefore, air-filled pore 22 is axially arranged, particularly, air-filled pore 22 is arranged in the tube wall of connecting pipe 24, and through ring flange 23 and through hole 11 conductings, so arrange and facilitate charger to be connected with charging connector 311, and can not impact between air-filled pore 22 and air admission hole 21, the inflation of gas-flow closure circle 31 and ball valve 4 can be carried out simultaneously, saves detection time.
Further, connecting pipe 24 is clearance fit with the inwall of ball valve 4.
Wherein, in the time that ball valve made of plastic 4 is detected, because ball valve made of plastic 4 easily deforms in the time being subject to internal stress, make ball valve made of plastic 4 produce larger ellipticity error, if connecting pipe 24 is tighter with coordinating of ball valve 4, can cause connecting pipe 24 to be difficult to extract from ball valve 4.Therefore, connecting pipe 24 is set to clearance fit with the inwall of ball valve 4, makes ball valve 4 after detection, facilitates connecting pipe 24 to extract from ball valve 4.
As preferably, the material of gas-flow closure circle 31 is silica gel.
In the utility model embodiment, this pick-up unit is symmetrical structure, for detection of the ball valve 4 with two ports.The connection at ball valve 4 two ends is all identical, does not repeat at this.
Above-mentioned the utility model embodiment sequence number, just to describing, does not represent the quality of embodiment.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
