Description
Technical field
This utility model belongs to engine assembly field, is specifically related to a kind of engine pipelines fast plugging device.
Background technology
During engine assembly, need the internal duct to electromotor, performing leak test is carried out including oil pipe and trachea, i.e. carry out passing in and out gas simulation to its main air inlet/outlet according to actual condition, when seal tightness test, must be sealed by other air inlet/outlets during test, and the effect sealed directly affects the accuracy of test result, these are imported and exported position and are the most all equipped with snap ring.Pipe fitting with flange brings extreme difficulties to performing leak test, and common sealing device is difficult to effectively seal, and is typically each to use sebific duct to add clip to carry out plug for seal, and seal process is loaded down with trivial details, and sealing effectiveness is the most undesirable.
Summary of the invention
Goal of the invention: this utility model purpose is for the deficiencies in the prior art, it is provided that a kind of flanged engine pipelines fast plugging device, closure is rapid, good sealing effect.
Technical scheme: engine pipelines fast plugging device described in the utility model, including the hollow seal seat being set on pipe fitting to be sealed, nesting is arranged on the spacing shell outside described seal receptacle, and the sealing piston being arranged in described seal receptacle；On the inwall of the open side of described seal receptacle, symmetry offers some through holes, steel ball is installed in through hole, described spacing casing is located at the outside of the open side of described seal receptacle, and rolling in the slide outside of described seal receptacle by described steel ball, the afterbody relevant position of described spacing shell is additionally provided with the unfilled corner accommodating described steel ball；Described sealing piston is fixed with described seal receptacle by the first compression spring, and is supported in the cavity of described seal receptacle under the effect of described first compression spring, seals the mouth of pipe of described pipe fitting to be sealed.
This utility model further preferably technical scheme is, the outer wall of the open side of described seal receptacle is provided with step surface, and described spacing shell is seated on described step surface.
Preferably, described step surface being provided with the second compression spring, the two ends of described second compression spring are fixed with described seal receptacle and spacing shell respectively, and described spacing shell resets under the effect of described second compression spring.
Preferably, the tail end of described seal receptacle is provided with torsion handwheel, and one end of described first compression spring is fixed on described sealing piston, and the other end is fixed on described torsion handwheel, regulates the elastic force of described first compression spring by regulating described torsion handwheel.
Preferably, described sealing piston is rubber seal plug.
The encapsulating method of fast plugging device of the present utility model is: slid back by spacing shell, steel ball free rolls, and when spacing shell slides into certain position, steel ball slips in the unfilled corner of spacing shell, whole plugging device is enclosed within pipe fitting to be sealed, unclamp spacing shell, spacing shell return in steel ball is clamp-oned the through hole of seal receptacle, now, it is symmetrically arranged with steel ball to be radially stuck on pipe fitting to be sealed, seal piston to withstand under the effect of the first compression spring on pipe fitting to be sealed, sealing orifice.
Beneficial effect: by seal receptacle and the cooperation of spacing shell in (1) this utility model, steel ball is radially overlayed on pipe fitting to be sealed, and the flange of clamping pipe fitting, guarantee that pipe fitting does not comes off, again by sealing the piston seal mouth of pipe in seal receptacle, simple to operate, closure is rapidly, and sealing effectiveness, do not interfere with the testing result of performing leak test；
(2) being provided with step surface in this utility model on the outer wall of the open side of seal receptacle, spacing shell is seated on described step surface, can limit the sliding distance of spacing shell, it is to avoid spacing shell slips；Fixed by compression spring between spacing shell and seal receptacle, spacing shell can under the effect of compression spring self-return, simplify operating process further；
(3) this utility model seals piston to be fixed on the torsion handwheel of seal receptacle tail end by compression spring, handwheel, the elastic force of regulation compression spring can be reversed by regulation, be adjusted sealing the closure power of piston.
