Abstract
The utility model relates to a safety exhaust depressurization device for a pressure cooker, which is composed of a base and a safety pressing sleeve, wherein the edge of the periphery of the base thereof is provided with three lever brackets, each of which is connected with a lever through a pin shaft; the top of the safety pressing sleeve of the utility model is connected with a screw cap through a screw rod. When the utility model is used, the base is first sheathed on the periphery of the lower part of an exhaust pipe on the lid of the pressure cooker, then a pressure limiting valve is sheathed on the periphery of the upper part of the exhaust pipe, and the safely pressing sleeve is pressed on the base before the lid is opened. The safety exhaust depressurization device for a pressure cooker can directly carry out exhaust and decompression and has the advantages of simple operation, convenient use, time economy and safety.
Description
The utility model relates to a kind of pressure cooker safety exhaust dropping equipment.
Existing pressure cooker has only a pressure limiting valve controlling the pot internal gas pressure on the market.Take off before the lid after it uses, must take the nature cooling or with just taking off lid after the step-down of cold water forced cooling.Both lost time like this, operate very inconvenient again, bad if time support is held, just can cause security incident.
The purpose of this utility model is to provide a kind of pressure cooker safety exhaust dropping equipment of direct exhaust step-down.
The utility model is achieved like this, it is made of a base and a safe gland.Be provided with 3 lever dollies on the exterior rim of its base equably, lever dolly is connecting a lever by a bearing pin, and the top of its safe gland is connecting nut by screw rod.
Advantage of the present utility model is before pressure cooker uses, earlier with base sheath in pressure cooker exhaust pipe lower part periphery, on demand pressure limiting valve is enclosed within periphery, blast pipe top again, before after pressure cooker uses, taking off lid, again safe gland is withheld on base, by lever pressure limiting valve is provoked like this, carry out safe exhaust step-down.Easy to use like this, simple to operate, both saved the time, can reach the purpose that safety is taken off lid again.
