The utility model is that the technical scheme that adopts that achieves the above object is: the combined explosion-proof valve of a kind of electrokinetic cell, comprise cover plate, explosion-proof valve port on the cover board is set, fix a valve seat at explosion-proof valve port, this valve seat is tubular, valve seat is laid sealing ring, and sealing ring is arranged on the explosion-proof valve port, places explosion-proof valve block on the sealing ring, valve base cavity arranges the tubulose compactor that compresses explosion-proof valve block, is provided with retaining mechanism between compactor and the valve seat.
Preferably, place the seal pad on the described explosion-proof valve block, compactor compresses explosion-proof valve block by the seal pad.
Preferably, described retaining mechanism is screw thread locking mechanism; Valve seat is cylindric, and its inwall is provided with screw thread; The outer wall of compactor is provided with the screw thread with the valve base inner wall threaded engagement, and the upper end of compactor is provided be used to being received the fluting of screwing tool.
The utility model can shorten the time of annotating electrolyte by the explosion-proof valve port electrolyte of annotating, and increases the production capacity of producing.
Description of drawings
Fig. 1 is the structure cutaway view of the utility model preferred embodiment.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in Figure 1, the combined explosion-proof valve of a kind of electrokinetic cell, comprise cover plate 1, be arranged on the explosion-proof valve port 2 on the cover plate 1, fix a valve seat 3 at explosion-proof valve port 2, this valve seat 3 is tubular, and valve seat 3 is laid sealing ring 4, sealing ring 4 is arranged on the explosion-proof valve port 2, place explosion-proof valve block 5 on the sealing ring 4, valve seat 3 inner chambers arrange the tubulose compactor 7 that compresses explosion-proof valve block 5, are provided with retaining mechanism between compactor 7 and the valve seat 3.
Retaining mechanism can adopt various ways.Described retaining mechanism is screw thread locking mechanism; Valve seat 3 is cylindric, and its inwall is provided with screw thread; The outer wall of compactor 7 is provided with the screw thread with the valve base inner wall threaded engagement, and the upper end of compactor 7 is provided be used to being received the fluting 71 of screwing tool.Place seal pad 6 on the described explosion-proof valve block 5, compactor 7 compresses explosion-proof valve block 5 by seal pad 6.
Retaining mechanism also can adopt the cam pressure rod structure, and cam is pressed on the compactor 7, and cam is fixed on the depression bar, and an end of depression bar is articulated on the valve seat 3.Also can adopt lever device, an end of lever is articulated on the valve seat 3, and lever is pressed on the compactor 7, and the other end of lever is fixed after compressing.
As shown in Figure 1, present embodiment is provided with boss at valve seat 3, and this boss inserts explosion-proof valve port 2, and valve seat 3 is fixed on the explosion-proof valve port 2 by welded seal; Valve seat 3 intracavity bottoms are provided with step, settle successively sealing ring 4, explosion-proof valve block 5, seal pad 6 on step, and compactor 7 press seal spare pads 6 pass through screw-threaded coupling between compactor 7 and the valve seat 3.Wherein, sealing ring 4 adopts EPDM Ethylene Propylene Terpolymer material.
Adopt laser welding that valve seat 3 is welded on explosion-proof valve port 2 at battery cover board 1, in the following order combination: sealing ring 4, explosion-proof valve block 5, seal pad 6 are placed on valve seat 3 the insides, and compactor 7 and valve seat 3 are combined is integrated at last.
The utility model can be by explosion-proof valve port filling electrolyte, because the bore of explosion-proof valve port is greater than existing electrolyte filler port, can shorten time of more notes electrolyte by explosion-proof valve port filling, improves production capacity.
