Abstract
The utility model relates to a partial structure for an open-stopping valve stem of a pressure cooker, which comprises a pressure cooker lid, wherein, an open-stopping valve stem which can slide un and down is arranged on a through hole on a concave point on one side edge of the pressure cooker lid. The utility model is characterized in that the middle part of the open-stopping valve stem is provided with a penetrating through hole, and a fusible partitioning slice is arranged in the lower side of the penetrating through hole. When the inner of the pressure cooker generates high temperature and high pressure and a safety valve on the pressure cooker can not release the pressure sue to malfunctions, high-pressure gas in the cooker can burst the fusible partitioning slice and rush out of a cooker body through the penetrating through hole so as to play the function of security protection.
Description
The utility model relates to a kind of part-structure of pressure cooker stopping valve bar.
The function that is arranged at the stopping valve bar on pressure cooker lid one through hole at present is: when pressure cooker pot inner pressure during greater than the atmospheric pressure in the external world, the stopping valve bar is up under the effect of pressure cooker pot inner pressure, thereby can stop the plate of being located in the pressure cooker upper handle of only opening to carry out breakdown action; When the pressure cooker pot inner pressure equated with atmospheric pressure, the stopping valve bar just fell after rise under the effect of deadweight, promoted only to open plate thereby be beneficial to the user, opened pot cover.Its weak point is that this stopping valve bar function of use is single, can not play the safeguard protection effect of release when the pressure cooker pot inner pressure is excessive.
The purpose of this utility model is the part-structure that a kind of pressure cooker stopping valve bar will be provided; when the pressure in the pressure cooker pot was big, this structure had restriction and only opens the function that plate is opened, when producing high temperature, high pressure in the pot; but this structure automatically unloading plays the effect of safeguard protection.
The utility model is to constitute like this, it comprises pressure cooker lid, be equipped with on the through hole of pressure cooker lid one lateral margin recess can upper and lower slip the stopping valve bar, it is characterized in that: stopping valve bar middle part offers runs through through hole, this runs through and is provided with meltable partition in the through hole.When the pressure cooker pot inner pressure was big, the stopping valve bar was up, thereby stoped the plate of being located in the pressure cooker upper handle of only opening to carry out breakdown action; When the safety valve when producing high temperature, high pressure in the pressure cooker pot on the pressure cooker for some reason can't release, the gases at high pressure in the pot just can break through meltable partition and go out a pot body through running through through hole, thereby play the safeguard protection effect.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the utility model organigram.
With reference to accompanying drawing, the utility model comprises pressure cooker lid, be equipped with on the through hole 2 of pressure cooker lid one lateral margin recess 1 can upper and lower slip stopping valve bar 3, it is characterized in that: stopping valve bar middle part offers runs through through hole 4, this runs through and is provided with meltable partition 5 in the through hole.
Has one section major thread through hole 6 on the above-mentioned port that runs through the through hole downside, meltable partition is located at and is run through through hole and major thread through hole junction, be connected with outer wall on the major thread through hole and have externally threaded Anti-stop cover 7, the last side opening of this Anti-stop cover is being pressed meltable partition, has cross air inlet sealing 8 on its downside base plate.
The utility model is novel, and is reasonable in design, and its application will make the pressure cooker product more safe and reliable.
