Abstract
The utility model relates to an improved safety plug for pressure cookers. The utility model comprises a rubber plug body fixedly arranged on a cooker cover, a plug sheet arranged in the plug body, a crack opening arranged on the edge of the plug sheet, and connecting ribs arranged on both sides of the crack opening. When the utility model is used and the air pressure in the pressure cooker is larger than the specified safety pressure, the plug sheet is cracked to be turned up, the air arranged in the pressure cooker can be released in time, and the plug sheet can not be pushed out of the plug body. The utility model has the advantages of simple structure, low cost, convenient installation, safe use, etc. The utility model is suitable for being assembled on the household pressure cooker.
Description
The utility model relates to the accessory of family expenses pressure cooker, particularly to having a kind of improvement of pressure cooker safety valve now.
The safeties of existing pressure cooker have two kinds, and a kind of is fuse sheet, and another kind is a safety valve, and the former is malfunctioning easily, does not often have the safety guarantee effect, and latter's production process is loaded down with trivial details, complex structure, cost height.The applicant has applied for that to Patent Office of the People's Republic of China application number is 96206039.9 " pressure cooker flame-arrester vent plug " on March 11st, 1996.This structure ejects flame-arrester vent plug outside the pot cover by the pressure that exceeds the quata in the pressure cooker, discharges a pot interior overvoltage gas, reaches pressure cooker purpose safe in utilization.But, still cause casualty accident easily because whole cock body is ejected outside the gag.
It is a kind of simple in structure that the purpose of the utility model is to provide, the pressure cooker flame-arrester vent plug that safety coefficient is higher.
The pressure cooker flame-arrester vent plug comprises the rubber cock body that has patch, and the cock body outer wall has the ring recess that matches with pot cover aperture, thickness; Have the fracture port that can disconnect with cock body along the patch edge, the cock body on fracture port both sides and patch have a dowel.
When the utility model is assemblied in when using on the pressure cooker hermetically, along with pot inner pressure raises, the patch of flame-arrester vent plug can be pushed up into hunchbacked shape by air pressure gradually, when the pot internal gas pressure rises above specified safe pressure (200KPa), patch disconnects and is started along fracture port, and at this moment, a pot internal gas pressure is in time discharged, and patch can not be rushed out cock body and cause casualty accident outward, so guaranteed the safety that pressure cooker uses.
Below in conjunction with embodiment shown in the drawings the utility model is further described.
Fig. 1 is the utility model structural representation.
Fig. 2 is the upward view of Fig. 1
Fig. 2 is that the utility model is assemblied in the schematic diagram on the pot cover.
Fig. 4 is patch explosion status figure.
The cock body 4 of pressure cooker flame-arrester vent plug is the garden tubular, and cock body 4 outer walls have the ring recess 1 that matches with pot cover 6 apertures, thickness.Have the patch 3 that fuses with it in the cock body 4, patch 3 is positioned at cock body 4 tops, also can be in cock body 4 bottoms or other position; The thickness of patch 3 is 1-2mm, patch 3 has fracture port 2 in the garden at its edge on week, when this fracture port 2 is 200KPa at pot body internal gas pressure, patch 3 and cock body 4 are disconnected, on the fracture port 2 patch 3 thickness be generally 0.3-0.8mm, decide on the pressure and patch 3 compression areas of pressure cooker.
On the annulus geosutures that fracture port 2 forms, be provided with a place not by the joint face of otch, this joint face is as the dowel 5 between cock body 4 and the patch 3, dowel 5 also can otherwise be connected cock body 4 with patch 3, fly in case detent plug sheet 3 is outwards ejected by air pressure, causes casualty accident.
When the pressure cooker flame-arrester vent plug used, along with the rising of pot internal gas pressure, patch 3 was become hunchbacked shape by roof pressure, if pot inner pressure surpasses the safe air pressure of regulation, patch 3 will be broken by the top and dig, and overvoltage gas is discharged from patch 3 holes that cock body 4 is dug, so can avoid the generation of accident.
The utility model embodiment shown in the drawings adopts silastic material, and is one time punching molded.Advantages such as it has simple in structure, and is easy for installation at the bottom of the cost, safe in utilization are particularly suitable for being assemblied on various types of family expenses pressure cookers.
