Embodiment
As shown in Figure 1, the utility model provides a kind of pressure-adjusting type battery anti-explosion valve, comprises explosion-proof valve base 1, adjustable valve gap 3 and the explosion-proof valve body 2 between the two;
Described explosion-proof valve base 1 is bolt shape, comprise hexagonal (hexagon)nut shape head and screw shaped connecting portion, on head, there is cylindrical explosion-proof groove 6, there is the relief hole 4 of a connection in the central axis position of described connecting portion, described relief hole 4 extends through the bottom of described explosion-proof groove 6 from the bottom of connecting portion, quick-fried valve base head side is evenly distributed with three steam vents 5, and described steam vent 5 one end are positioned at the madial wall bottom of explosion-proof groove 6, and its other end is positioned at the outside of head;
Explosion-proof valve body 2 is cylindrical ethylene propylene diene rubber valve body, and explosion-proof valve body 2 is positioned at described explosion-proof groove 6 and relief hole 4 is covered with that one end that explosion-proof groove 6 is connected;
Adjustable valve gap 3 is positioned at explosion-proof valve body 2 tops, and the madial wall of its lateral wall and explosion-proof groove 6 is threaded connection, and adjustable valve gap 3 tops have groove;
Explosion-proof valve base 1 is stainless steel or irony nickel plating with adjustable valve gap 3, and stainless steel or irony nickel plating material capability are stable, long service life.
The course of work of this example: explosion-proof valve body 2 is placed in the explosion-proof groove 6 of explosion-proof valve base 1, make explosion-proof valve body 2 cover relief hole 4 completely, the height of explosion-proof valve body 2 is lower than the degree of depth of explosion-proof groove 6, explosion-proof valve body 2 is positioned at explosion-proof groove 6 inside completely, adjustable valve gap 3 is placed in to explosion-proof groove 6 tops rotary adjustable valve gap 3, make adjustable valve gap 3 move downward and contact with explosion-proof valve body 2 upper surfaces under the acting in conjunction of outside screw and explosion-proof groove 6 inside threads, continue to be rotated down adjustable valve gap 3, thereby extruding is out of shape explosion-proof valve body 2 and is produced different explosion-proof pressures,
