Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
With reference to shown in Fig. 1 to Fig. 5, a kind of vacuum pipe package seal checker, including the first body are present embodiments provided 1st, the second body 2, the internal layer sealed connecting component 34 being arranged between the opposite end surface of the body 2 of the first body 1 and second With outer layer sealed connecting component 35 and for detecting the internal layer sealed connecting component 34 and the air-tightness of outer layer sealed connecting component 35 Seal for pipe joints testing agency 80；Seal cavity 36 in a ring between the internal layer sealed connecting component 34 and outer layer sealed connecting component 35 Set, the vacuum pipe insertion company of the seal for pipe joints testing agency 80 respectively with the ring packing cavity 36 and after be connected Connect.
Specifically, in the present embodiment, the seal for pipe joints testing agency 80 includes being used to obtain ring packing cavity 36 First sense channel of ratio between atmospheric pressure value and external perimysium reference atmospheric pressure value, for obtain the atmospheric pressure value of ring packing cavity 36 with it is true The second sense channel of ratio and compare between vacant duct for obtaining between vacuum pipe atmospheric pressure value and external perimysium reference atmospheric pressure value 3rd sense channel of value, first sense channel, the second sense channel and the 3rd sense channel with the automatically controlled dress in outside Electrical connection is put, first sense channel, the second sense channel and the 3rd sense channel are provided with baroceptor and logical Air valve.
With the seal for pipe joints testing agency of this structure design, can timely and effectively it be obtained by the setting of each sense channel The air pressure change in the vacuum pipe after ring packing cavity 36 and connection is taken, and then judges internal layer sealed connecting component 34 or outer layer The sealing of sealed connecting component 35, is timely and effectively safeguarded with facilitating.Designed using aforesaid way, each passage is collected Data by outside electric control gear analysis judge after, by correspondence sense channel on breather valve be adjusted, then The air pressure ratio of each sense channel is adjusted, with the vacuum in this Equilibrium vacuum pipeline, simultaneously, additionally it is possible to according to the number got According to remotely judging Gas leak position, and will appear from the case where not influenceing the vacuum in vacuum pipe the internal layer sealing of problem Connector or outer layer sealed connecting component are individually replaced.
Further, in the present embodiment, the opposite end surface of the body 2 of the first body 1 and second is provided with internal layer Circular orientation circle 43 and outer annular centring ring 44；The two ends of the internal layer sealed connecting component 34 respectively with the corresponding internal layer Circular orientation circle 43 is fastened；The two ends of the outer layer sealed connecting component 35 are tight with the corresponding outer annular centring ring 44 respectively Gu, the two ends of the outer layer sealed connecting component 35 are fastened by pricking hoop 5 with the outer annular centring ring；The internal layer sealing connects The two ends of fitting 34 are fastened by the annular centring ring 43 of screw rod 6 and the internal layer, and the annular centring ring 43 of the internal layer is circumferential uniform There are multiple mounting holes, one end of the mounting hole is embedded with the nut 7 that the screw rod 6 is engaged, the internal layer sealed connecting component 34 is identical with the structure of outer layer sealed connecting component 35, and the internal layer sealed connecting component 34 and outer layer sealed connecting component 35 are provided with edge Periphery radial direction recessed the first arcwall 31 and the second arcwall 32, and horizontal extension is in the outer end of the second arcwall 32 Positionable wall 33, second arcwall 32 seamlessly transits the two ends for being arranged at first arcwall 31, and first arc Shape wall 31 and the recessed setting in opposite direction of second arcwall 32, the opposite end surface of the body 2 of the first body 1 and second Circular orientation circle 40 is convexly equipped with, the circular orientation circle 40 includes the fixed part 41, Yi Jiyu fastened with the positionable wall 33 The sealing 42 that the concave surface of second arcwall 32 is brought into close contact, the ring-type of sealing 42 is convexly equipped in the circular orientation circle 40 side face.
In the present embodiment, the atmospheric pressure value of the inner concave of the first arcwall is less than the first arcwall in the vacuum pipe after connection Outer concave surface atmospheric pressure value, with this inner concave of the second arcwall is brought into close contact with sealing, so play very well Sealing function, further, since the setting of internal layer sealed connecting component 34 and outer layer sealed connecting component 35, and outer layer sealed connecting component 35 are fixed with the outer annular centring ring 44 by pricking hoop 5, are conveniently installed and are tieed up on the outside of vacuum pipe with this Repair；Internal layer sealed connecting component 34 is fixed with the annular centring ring 43 of the internal layer by screw bolt and nut, convenient from true with this Internal layer sealed connecting component 34 is installed and repaired in vacant duct cavity.Design in this way, can not only effectively lift phase Air-tightness after being connected between adjacent vacuum pipe, but also can facilitate to internal layer sealed connecting component 34 and outer layer sealed connecting component 35 are installed and are repaired.
