Abstract
The utility model relates to an explosion-proof pressure cooker cover which is composed of an air outlet nozzle arranged on the cooker cover, a sealing ring and a pressure limiting valve matched with the air outlet nozzle, wherein, the cooker cover is an entirety formed by a pressure bearing cover and a tight hanging plate, and the air outlet nozzle is fixed to the pressure bearing cover and the tight hanging plate by fasteners. When an air hole of the air outlet nozzle is blocked, the pressure in the pressure cooker rises to the set limiting value, the middle concave part of the pressure bearing cover deforms and is jacked up upwards under the function of the pressure, and a gap is formed between the air outlet nozzle and the pressure bearing cover. Steam is discharged out of the gap, and the goal of decompression is realized. The explosion-proof pressure cooker cover is safe and reliable, and the pressure limiting value in the pressure cooker can be regulated by the fasteners.
Description
The utility model relates to a kind of pot cover of pressure cooker, particularly a kind of explosion-proof pressure pot cover with explosion prevention function.
For making relieved, the working pressure pot safely of consumer, general pressure cooker has all been taked safety measure, just increased disappointing step-down explosion prevention function as the patent No. 96210295.4 " pressure cooker use safeties ", but its safety device is mounted in the upper handle of pressure cooker.
The purpose of this utility model is to provide a kind of explosion-proof pressure pot cover, and is easy to use, reliable, and safety coefficient is higher, has explosion prevention function.
The utility model is achieved in that the explosion-proof pressure pot cover is made up of the pressure limiting valve that is installed in outlet nozzle on the pot cover, sealing ring and cooperate with outlet nozzle, the integral body that described pot cover is connected into by pressure cap and fastening plate, and outlet nozzle is fixed on pressure cap and the fastening plate with securing member.
Accompanying drawing: structural representation of the present utility model.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Pressure cap (1) be mid portion to recessed, there is through hole the centre, lower limb has the pot cover shape of fastening groove.
Fastening plate (2) also can be circle for the middle bar shaped that screwed hole is arranged, and is fixed on spot welding or other method on the both sides of pressure cap (1) recessed portion periphery symmetry, connects into whole pot cover.
Outlet nozzle (3) is the middle multistage step cylindricality that through hole is arranged, and the top surface edge of lower end has annular groove to cooperate with packing ring (7), and screw is arranged on the lower surface, and axially the periphery of middle part has external screw thread.
Protective cover (8) is
Shape has slit or aperture on the surface.
Pressure limiting valve (5), protective cover (6) are same as the prior art.
The outlet nozzle (3) that will have packing ring (7) passes pressure cap (1), is fixed on the fastening plate (2) with screw thread, and locks with nut (4).Again protective cover (8), protective cover (6) are screwed in the screw of outlet nozzle (3) lower surface.
During use,, and cover on one's body pot, again pressure limiting valve (5) is enclosed within on the outlet nozzle (3), just can use edge, the outer ring embedding sealing ring (9) of this pot cover.When pressure cooker pressure is in the service pressure scope, steam is by protective cover (6), protective cover (8) and outlet nozzle (3) central through hole, jack-up pressure limiting valve (5) and will discharging in the gas through hole from it, when if the pore on the outlet nozzle (3) is blocked, after pot inner pressure rises to the limiting pressure of setting, pressure cap (1) mid portion is jack-up because the pressure effect makes progress, make between itself and outlet nozzle (3) and the packing ring (7) and form certain clearance, this is that steam just discharges by this gap, thereby has reached the purpose of pressure release.
The utility model is compared with prior art: carry out pressure release because utilizing the distortion of pressure cap mid portion, therefore Just can omit safety valve. The pressure release holding device of existing pressure cooker all adopts the aperture exhaust mode, is easy to draw Playing food stops up. And this lid adopts plane clearance pressure release mode, can not cause the food clogging. Simultaneously logical Overregulate outlet nozzle and nut and can regulate the interior limiting pressure of pot, can become according to the difference of each batch material when dispatching from the factory Change and regulate, assurance pot interior limiting pressure value is in certain allowed band, and therefore use safely, reliably. Because pressure release just having explosion prevention function, can guarantee that the user is perfectly safe.
Claims (3)
1. explosion-proof pressure pot cover, form by being installed in outlet nozzle, sealing ring (9) on the pot cover and the pressure limiting valve (5) that cooperates with outlet nozzle, it is characterized in that the integral body that described pot cover is connected into by pressure cap (1) and fastening plate (2), and outlet nozzle (3) is fixed on pressure cap (1) and the fastening plate (2) with securing member.
2. pot cover as claimed in claim 1 is characterized in that: pressure cap (1) for mid portion to recessed, there is through hole the centre, lower limb has the pot cover shape of fastening groove; Fastening plate (2) also can be circle for the middle bar shaped that screwed hole is arranged, and is fixed on spot welding on the both sides of pressure cap (1) recessed portion periphery symmetry, connects into whole pot cover; Outlet nozzle (3) is the middle multistage step cylindricality that through hole is arranged, and the top surface edge of lower end has annular groove, and screw is arranged on the lower surface, and axially the periphery of middle part has external screw thread, is screwed protective cover (8), protective cover (6) in the screw of lower surface.
3. pot cover as claimed in claim 1 or 2 is characterized in that: protective cover (8) is
Shape has slit or aperture on the surface.
