Abstract
The utility model relates to articles for daily use, specifically an auxiliary safety component of pressure cooker. A safety valve composed of a limit, a gasket, a valve core, a screw nut and a valve body is equipped at the proper position off the edge for 25-35 millimetre of the cover of a pressure cooker. The upper part of the body of the pressure cooker is equipped with a limit fender in corresponding with the limit disk. After being equipped with the auxiliary safety component of pressure cooker, the pressure cooker has the functions that the pressure in the pressure cooker can not be ascended if the cover of the pressure cooker is not covered in the right position and the cover of the pressure cooker can not be opened when the pressure cooker has the pressure. The auxiliary safety component of pressure cooker has simple structure, easy manufacturing, strong safety performance, reliable safety performance, and can be assembled to the pressure cookers with various models and specifications.
Description
The utility model relates to daily living article, the pressure cooker auxiliary security parts of specifically a kind of kitchen cooking utensils.
The cooking utensils pressure cooker that people use always takes place for preventing the interior superpressure contingency of pot in use, generally is to be provided with blast pipe and pressure limiting valve at the pot cover middle part, the safety valve of dress fuse sheet in the pot cover upper lateral part is established.Usually the qualification pressure in the pot is 100Kpa, raise when exceeding 2 times of left and right sides of level pressure power as pot inner pressure, and the fuse sheet fusing in the pot cover upper lateral part safety valve, steam is discharged from safety valve, pot inner pressure is descended reach the assurance purpose of safety.As the pressure in the pot higher (being lower than the force value of fuse sheet fusing), and be eager to uncap or faulty operation without pressure release again, can let out because of expandable gas in the pot is prominent and cause the accident of user's permanent disability to happen occasionally.When safety valve can only be worked as pressure above setting, melt pressure release by fuse sheet, when pressure is lower than setting, also have certain pressure in the pot, pot cover is opened, and can have an accident to bring unnecessary loss to the user.How just can make the pressure cooker security insurance, to make the user relieved, be that relevant department very pays close attention to anxious to be solved always.
The purpose of this utility model provides a kind of when the maloperation of folding pot cover, can not cause the accident that do not have to take place, and can play the pressure cooker safeties of security insurance effect.
Technical essential of the present utility model is:
Being on the 25-35 millimeter appropriate location apart from the edge on the pressure cooker cover, be provided with the easing valve that constitutes by position-arresting disk, packing ring, spool, nut and valve body, the spacing shelves (referring to Fig. 1 and Fig. 2) with the corresponding setting of position-arresting disk are arranged at pot body top.The hollow revolving body of the flanged dish in upper end, spool (5) lower end joins by screw thread and position-arresting disk (3) middle part, and be with packing ring (9), inwall has in the valve body (8) of vertical exhaust trench (10) spool (5) that is free to slide is housed, the packing ring (6) that is equipped with on the convex edge on valve body (8) top contacts with pot cover (4) inner face, and the nut (7) of pot cover (4) outside screws valve body (8) exposed section, top by screw thread; The corresponding L shaped spacing shelves (2) that are provided with position-arresting disk (3) are riveted on the top pot wall (1) of pot body.
After pressure cooker has been installed this device, have pot cover and close not sternly, pot inner pressure can not raise, as the function that has pressure, pot cover not to open in the pot.It is simple in structure, be easy to processing, and safety performance is strong, and is safe and reliable, can be applied on the pressure cooker of any specification, model.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the A-A view of Fig. 1.
Fig. 3 is the utility model installation site schematic diagram on pot cover.
Fig. 4 is the vertical view of Fig. 3.
The equidistant measure-alike vertical exhaust trench (10) that has on valve body (8) inwall is 3-8, in order to release the pressure in the pot.Pot cover (4) outer rim is provided with the protruding shelves (11) of inside punching out, and when upper and lower handle overlapped fully, the relative serratd edge contact with the pot body of protruding shelves was used for preventing opening clockwise pot cover (4).Suitably reduce with the size of the corresponding pot of the protruding shelves of pot cover (11) body serratd edge by protruding shelves (11), effect is to make the pot cover can only be chimeric on the position of stipulating.During installation, at first spool (5) is passed valve body (8) and position-arresting disk (3) and screws by screw thread and be one, pack the installing hole of pot cover (4) into from pot cover (4) inner face then in, it is fastening to add nut (7) in pot cover (4) outside.Valve body (8) top joins by the inner face of packing ring (6) with pot cover (4), and nut (7) is fastened to valve body (8) top, packing ring (6) and the sealing of pot cover (4) inner face.
During use, overlap fully when pressure cooker is incorporated into upper and lower handle, and in the pot during no pressure, easing valve is in off working state, promptly spool does not lift.When the upper and lower handle of pressure cooker overlaps fully, pot inner pressure is elevated to 5Kpa when above, and spool lifts, packing ring on the position-arresting disk seals the valve body exhaust trench, position-arresting disk contacts with the limiting block of riveted on the pot wall, the pot cover of at this moment just not opening, and promptly easing valve is in running order.If upper and lower handle does not overlap fully, when pot inner pressure promotion spool lifts, limiting block has limited spool and has lifted, the exhaust trench of packing ring on the position-arresting disk on can not closed valve, pot inner pressure is drained by the valve body exhaust trench be controlled at below the 5Kpa, therefore guaranteed the safe in utilization of pressure cooker.
Claims (3)
1, a kind of pressure cooker safeties that constitute by easing valve and limiting block, it is characterized in that being on the 25-35 millimeter appropriate location apart from the edge on the pressure cooker cover, be provided with the easing valve that is made of position-arresting disk, packing ring, spool, nut and valve body, the spacing shelves with the corresponding setting of position-arresting disk are arranged at pot body top; Hollow revolving body spool (5) lower end of the flanged dish in upper end joins by screw thread and position-arresting disk (3) middle part, and be with packing ring (9), inwall has in the valve body (8) of vertical exhaust trench (10) spool (5) that is free to slide is housed, the packing ring (6) that is equipped with on the convex edge on valve body (8) top contacts with pot cover (4) inner face, and the nut (7) of pot cover (4) outside screws valve body (8) exposed section, top by screw thread; The corresponding L shaped spacing shelves (2) that are provided with position-arresting disk (3) are riveted on the top pot wall (1) of pot body.
