Under normal circumstances, because the fixation of the flat-top end of bleed screw, explosion-proof diaphragm can not broken through by pressure, and when pressure was excessive, explosion-proof rupture of diaphragm played the decompression protection effect.
There is following point in existing safety anti-explosive assembly:
1, change explosion-proof diaphragm inconvenience: explosion-proof diaphragm can need to not taken out it with the delivery pin along with bleed screw is taken out of, has caused the placement of explosion-proof diaphragm and the inconvenience of taking, and causes user's operation sense not good;
2, can't guarantee the correct placement of explosion-proof diaphragm: when placing explosion-proof diaphragm, explosion-proof diaphragm flattens sometimes, causes easily gas leakage, the carrying out smoothly or obtain correct experimental result of impact experiment;
3, influential to the flatness of air vent inwall: as when getting the film pin, hermetically sealed can air vent inwall can be chosen hair, affect the fitness of explosion-proof diaphragm and tank skin.
The utility model content
Technical problem to be solved in the utility model provides a kind of anti-explosion safety structure for micro-wave diminishing pot, it is by the sunk structure with the arc gap at the bleed screw front end, explosion-proof diaphragm is inlayed the front end that is fixed on bleed screw, both be convenient to the replacing of explosion-proof diaphragm, can avoid again the injury to hermetically sealed can air vent inwall, and explosion-proof diaphragm accurate positioning, the safety measure of micro-wave diminishing pot obtains real assurance and raising.
The technical solution of the utility model is: a kind of anti-explosion safety structure for micro-wave diminishing pot is provided, comprises bleed screw and explosion-proof diaphragm, it is characterized in that: at the front end of bleed screw, a recessed groove structure with the arc gap is set; Described explosion-proof diaphragm is arranged in the recessed groove with the arc gap; Air vent bottom at counteracting tank arranges protruding round platform; The external diameter of its described protruding round platform is less than the internal diameter of bleed screw front end recessed groove; Described protruding round platform and recessed groove structure are complementary, and described explosion-proof diaphragm is clamped between the two.
The air vent of its described counteracting tank and bleed screw are threaded connection fixing.
Its described explosion-proof diaphragm is slidably disposed in the recessed groove of bleed screw front end with the arc gap.
Concrete, the action of the arc gap of its described bleed screw front end is less than the radius of recessed groove openend.
The opening chord length of its described arc gap is less than or equal to the diameter of explosion-proof diaphragm.
Further, the front end at described bleed screw front end arc gap recessed groove arranges spacing preiection.
The point diameter of its described arc gap recessed groove with spacing preiection is less than the diameter of explosion-proof diaphragm.
Compared with the prior art, the utility model has the advantages that:
1. explosion-proof diaphragm is placed in the recessed groove of bleed screw with the arc gap, and accurate positioning can not drop out;
2. explosion-proof diaphragm and being integral of bleed screw structure, integral replacing is convenient;
3. employing the technical program has been avoided many defectives of existing anti-explosion safety structure, so that the safety measure of micro-wave diminishing pot obtains real assurance and raising.
