Abstract
The utility model relates to a rapid sealing plug which comprises a casing, a piston, an end cover, a sealing ring, magnets, hollow gaskets, solid gaskets and three O-shaped rings, wherein an inner thread is formed at one end of the casing, the end with the thread, of the casing and the end cover are connected through the thread and locked through a screw, and two air inflation ports and two installation threaded holes are formed in the other end of the casing. Space between the piston and the casing are sealed through the O-shaped rings positioned between the end cover and the piston, the sealing rings are separated from the end cover through the hollow gaskets, and the magnets are arranged between the sealing rings and the piston and separated from the sealing rings through the solid gaskets. The rapid sealing plug has the advantages of being reasonable in structure, safe and reliable, easy to operate and maintain and the like, can seal air inlet and outlet pipes towards different directions, and has three air inflation modes which can be chosen according to dimensions of the air inlet and outlet pipes.
Description
Technical field
The utility model relates to turbosupercharger air tightness test technology, particularly a kind of quick-sealing plug during for turbosupercharger air tightness test.
Background technique
Turbosupercharger air tightness test passes in and out gas simulation according to actual conditions to its main air inlet/outlet, other air inlet/outlets must be sealed, and the effect of sealing directly affects the accuracy of test result when test.Therefore, the sealing of air inlet/outlet is one of key technology of turbosupercharger air tightness test.
The sealing problem of the FE series quick connector that Fastest company of the U.S. produces can not solve that Open Side Down well formula tracheae.In addition, because it only has an inflation inlet, airing form only has one, makes its application area and uses flexibility to be restricted.
Model utility content
The technical problems to be solved in the utility model is: the problems such as the degree of accuracy of existing air tightness test instrument is low in order to overcome, using scope and flexibility are all restricted, provide a kind of rational in infrastructure, safe and reliable, easy operating and maintenance, quick-sealing plug for the sealing of metal material turnover tracheae.
The utility model solves the technological scheme that its technical problem adopts: a kind of quick-sealing plug, comprise shell, piston, end cap, seal ring, magnet, hollow pad, solid shims and three O type circles, shell one end has internal thread, this one end of shell is connected with end cap by screw thread, and by screw lock, the shell the other end has two inflation inlets and two installation tapped holes, between piston and shell, sealed by O type circle, seal ring is installed between end cap and piston, between seal ring and end cap, separate with hollow pad, magnet is installed between seal ring and piston, between magnet and seal ring, separate by solid shims.
The beneficial effects of the utility model are: this quick-sealing plug has the features such as rational in infrastructure, safe and reliable, easy operating and maintenance, can solve the various sealing problems towards turnover tracheae, and there are three kinds of airing forms, can be according to the suitable airing form of size Selection of turnover tracheae.
Brief description of the drawings

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, shown in 2, a kind of quick-sealing plug, comprise shell 1, piston 2, end cap 3, seal ring 6, magnet 7, hollow pad 4, solid shims 5 and three O type circles 8, shell 1 one end has internal thread, shell 1 this one end is connected with end cap by screw thread, and lock with screw 9, shell 1 the other end has two inflation inlets 10 and two installation tapped holes, between piston 2 and shell 1, sealed by O type circle 8, seal ring 6 is installed between end cap 3 and piston 2, between seal ring 6 and end cap 3, separate with hollow pad 4, magnet 7 is installed between seal ring 6 and piston 2, between magnet 7 and seal ring 6, separate by solid shims 5.
Operating process and the working principle of sealing plug are: first quick-sealing plug is inserted to the turnover tracheae that needs sealing, under the effect of magnet, seal plug can hold tracheae automatically, makes the center of seal plug parallel with tracheae center; Then be filled with the gas through purge drying, can produce impacting force to seal ring at the effect lower piston of gas pressure, in the time that seal ring external diameter is constant, its internal diameter must shrink, and makes tracheae sealed.
