Abstract
The utility model relates to a safety plug for pressure cookers, which belongs to the improvement on the safety valve for household pressure cookers. The utility model comprises a plug body, a plug sheet fixed in the plug body, and a circular groove which is arranged on the outer wall of the plug body and is matched with a safety hole of a cooker cover. When the utility model is in use and the pressure in the pressure cooker is larger than the rating pressure, the safety plug can be automatically propped out of the cooker cover by air pressure and the air in the pressure cooker can be quickly exhausted so that the use safety of the pressure cooker can be ensured. The utility model is suitable for being assembled on the ordinary household pressure cooker, having the advantages of simple structure, low cost, convenient installation, etc.
Description
The utility model relates to a kind of improvement of safety valve on the accessory of family expenses pressure cooker, particularly pressure cooker.
Existing pressure cooker is safe in utilization in order to guarantee it, usually all on pressure cooker lid, load onto safety valve or fuse sheet, when the pressure in the pot body surpassed specified air pressure (200KPa), safety valve or fuse sheet can discharge gas in the pot automatically, thereby guarantee the safety that pressure cooker uses.But the former production process is cumbersome, complex structure, cost height; The latter tends to malfunctioning, does not have the safety guarantee effect.
It is a kind of simple in structure, easy to make that the purpose of the utility model is to provide, the pressure cooker flame-arrester vent plug that safety coefficient is high.
The pressure cooker flame-arrester vent plug comprises and is rubber cock body cylindraceous, with the patch that cock body fuses, has ring recess on the cock body outer wall, and ring recess matches with the safety vent of pressure cooker cover.
When the utility model is assemblied in when using on the pressure cooker hermetically, rising along with air pressure, the cover plate of flame-arrester vent plug will be pushed up into hunchbacked shape by air pressure gradually, if rising, the pot internal gas pressure surpasses specified air pressure, flame-arrester vent plug is discharged the interior gas that takes the dish out of the pot outward and rapidly by the automatic ejecting cap of air pressure, thereby has guaranteed the safety that pressure cooker uses.
Because the utility model adopts silicon rubber one time punching molded, thus have simple in structure, advantage such as cost is low, and is easy for installation; And can judge pot internal gas pressure size according to the hunchbacked shape of cover plate, in time grasp and uncap the time.
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the utility model is engaged in the state diagram when using on the pressure cooker cover.
Fig. 3 is the another kind of structural representation of the utility model.
Pressure cooker flame-arrester vent plug cock body 2 is the garden tubular, is shaped on the patch 1 that fuses with cock body 2 in the cock body 2, and patch 1 is positioned at cock body 2 tops, also can see Fig. 1, Fig. 3 in cock body 2 bottoms or other position; The thickness of cover plate 1 is 1-2mm, and cock body 2 outer walls have ring recess 3, and forms upper and lower sealing lip limit 4,5, and the width on last sealing lip limit 4 is generally at 1-2mm, and the width on lower seal lip limit 5 is 1.5-3mm, decides on the diameter of patch 1.The diameter of ring recess 3, thickness equate with pot cover 6 safety vent internal diameters, thickness.
When the pressure cooker flame-arrester vent plug uses, rising along with the pot internal gas pressure, cover plate 1 is become hunchbacked shape by roof pressure, at this moment, Fig. 2 is seen in patch 1 pulling lower seal lip limit 5 perks, if pot inner pressure surpasses the safe air pressure of regulation, flame-arrester vent plug will be ejected outside the lid automatically, and overvoltage gas is discharged from pot cover 6 safety vents, so can avoid the generation of accident.
The utility model embodiment shown in the drawings adopts silastic material, and one time punching molded, it is of a size of: cock body internal diameter φ 112mm, and high h6mm, ring recess diameter phi 216mm, lower seal lip hem width degree L12mm, last sealing lip hem width degree L21mm, patch thickness is 1mm.
Claims (2)
1, a kind of pressure cooker flame-arrester vent plug is characterized in that: it comprises and is rubber cock body 2 cylindraceous that the patch 1 that fuses with it is arranged in cock body 2, has ring recess 3 on cock body 2 outer walls.
2, pressure cooker flame-arrester vent plug according to claim 1 is characterized in that: the width on ring recess 3 formed lower seal lip limits 5 is 1.5～3mm, and patch 1 thickness is 1-2mm.
