Abstract
The utility model discloses a kind of circuit breaker inflation quick release coupling, belong to pneumatic element; Aim to provide and a kind ofly can be connected with multiple sulfur hexafluoride gas circuit breaker the pneumatic quick-change coupler of tonifying Qi.It comprises the pipe plug suitable with one-way valve; One-way valve by the valve seat (7) of taper hole, be located at steel ball (6) in each taper hole, be located at locking cover (4) on valve seat (7), be located at Returnning spring (5) between this locking cover and valve seat (7), be located at valve (8) and shutter spring (9) formation in valve seat (7); On pipe plug (2), there are lock ring groove and sliding sleeve (3), between this sliding sleeve and pipe plug (2), have locking spring (12); On valve seat (7), have on transit joint (10), pipe plug (2) and have transition piece (1).The utility model is simple in structure, easy to use, exchange highly versatile; It is a kind of pneumatic quick-change coupler that can mate with multiple sulfur hexafluoride gas circuit breaker.
Description
Technical field
The utility model relates to a kind of inflation quick release coupling, relates in particular to a kind of sulfur hexafluoride gas circuit breaker quick release coupling.
Background technique
As everyone knows, sulfur hexafluoride breaker operation a period of time after, sulfur hexafluoride gas (SF wherein
6) pressure can decline, need to supplement sulfur hexafluoride gas to circuit breaker.At present, conventionally adopt quick release coupling to supplement sulfur hexafluoride gas, the quick release coupling of Dan Ge circuit breaker producer is not only complicated, and between the quick release coupling of different manufacturers and circuit breaker, can not exchange each other generally, causes the wasting of resources; In addition, also need to carry the gas-charging connection of plurality of specifications and model when overhaul of the equipments personnel go out to overhaul, not only heavy, but also trouble, managed very inconvenient.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide a kind of circuit breaker inflation quick release coupling that can be connected with Multiple Type, specification sulfur hexafluoride gas circuit breaker tonifying Qi.
To achieve these goals, the utility model by the following technical solutions: it comprises the pipe plug suitable with one-way valve; Described one-way valve by wall be provided with some taper holes valve seat, be located at the steel ball in taper hole described in each, be located at the locking cover that on valve seat, steel ball blocked, be located at Returnning spring between this locking cover and valve seat, be located at valve in valve seat, be located at the shutter spring in valve seat, this valve being pressed on valve port and form; On pipe plug, there are lock ring groove and sliding sleeve, between this sliding sleeve and pipe plug, have locking spring; The right-hand member of valve seat has the left end of transit joint, pipe plug to have transition piece.
Transit joint is by screw thread and valve seat, and transition piece is union or flange plate.
Compared with the prior art, the utility model is owing to having adopted technique scheme, not only simplify the structure, and increased transit joint at the right-hand member of valve seat, left end at pipe plug has increased the transition pieces such as union or flange plate, therefore only need change transition piece according to the interface of circuit breaker, or according to the interface of gas cylinder (or air pump), change transit joint and can carry out tonifying Qi to circuit breaker; Effectively overcome the defect of quick release coupling that the maintenance of originally going out must be carried One's name is legion, both facilitated service kit management, improved service work efficiency, overcome again the defect of the wasting of resources; Have simple in structure, easy to use, exchange the advantages such as highly versatile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is use stateful connection schematic diagram of the present utility model.
In figure: transition piece 1, pipe plug 2, sliding sleeve 3, locking cover 4, Returnning spring 5, steel ball 6, valve seat 7, valve 8, shutter spring 9, transit joint 10, jump ring 11, locking spring 12.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1～2: the utility model forms by one-way valve and with the suitable pipe plug of this one-way valve.Described one-way valve by wall be provided with some taper holes valve seat 7, be located at the steel ball 6 in taper hole described in each, be located at the locking cover 4 that on valve seat 7, steel ball 6 blocked, be located at that this locking is overlapped and valve seat 7 between Returnning spring 5, be located at valve 8 in valve seat 7, be located at the shutter spring 9 in valve seat 7, this valve being pressed on valve port and form; The right-hand member of pipe plug 2, for the cone structure with pore (not indicating in figure), has lock ring groove (not indicating in figure) and sliding sleeve 3 on this pipe plug, between this sliding sleeve and pipe plug 2, have locking spring 12; The right-hand member of valve seat 7 has the transit joint 10 being attached thereto by screw thread, the left end of pipe plug 2 to have transition piece 1, and this crosses link can be union or flange plate.
For fear of locking cover 4, from valve seat 7, come off, on this valve seat, be fixed with jump ring 11; In like manner, for fear of sliding sleeve 3, from pipe plug 2, come off, on this pipe plug, be fixed with another jump ring 11.
During use, transition piece 1 is connected to (not shown) with the interface of circuit breaker, transit joint 10 is connected with gas cylinder or air pump (not shown) by flexible pipe, will pipe plug 2 insert and in valve seats 7, can back down valve 8 and be communicated with; Steel ball 6 falls into described annular groove and will manage plug 2 location simultaneously, and sliding sleeve 3 holds out against locking cover 4 to the right and taper hole is sealed under the effect of locking spring 12 subsequently, thereby will manage plug 2 and one-way valve secure lock.After inflation, promoting locking cover 4 left can open taper hole, then extracts pipe plug 2; Meanwhile, valve 8 is closed described valve port under the effect of shutter spring 9, avoids Leakage Gas.
Claims (2)
