The specific embodiment
Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to qualification of the present utility model, simultaneously by illustrating that advantage of the present utility model will become clear more and understands easily.
Consult accompanying drawing as can be known: the utility model limiting valve of pressure cooker, it comprises valve pocket 11, steam vent 12 is arranged on the valve pocket 11, the centre is fixed with spool 6 in the valve pocket 11, valve body 1 is fixed in the valve pocket 11, there is base 4 lower end of valve pocket 11, blast pipe 3 is fixed on the base 4, and pass base 4 and valve body 2 centers, the mouth of pipe of blast pipe 3 and spool 6 couplings is characterized in that on the described base 4 flutedly 9, and there is the projection 13 with groove 9 couplings described valve body 1 lower end, projection 13 is an one with valve body 1, and described valve pocket 11 outer surfaces have valve handle 7.Grab 2 is arranged, draw-in groove 5 couplings of described grab 2 and base 4 outers (when the mouth of pipe of spool 6 sealing blast pipes 3, grab 2 just in time is stuck in the draw-in groove 5, make seal the location more accurate) on the valve pocket 11.Inclined-plane 16 (inclined design makes moving of projection 13 easier, can easily move to the upper surface 10 of base 4) for projection 13 motions is arranged on the groove 9.
The utility model pressure limiting pot cover, it comprises limiting valve of pressure cooker and pot cover 8, limiting valve of pressure cooker comprises valve pocket 11, steam vent 12 is arranged on the valve pocket 11, the centre is fixed with spool 6 in the valve pocket 11, valve body 2 is fixed in the valve pocket 11, there is base 4 lower end of valve pocket 11, blast pipe 3 is fixed on the base 4, and passing the mouth of pipe and spool 6 couplings behind base 4 and valve body 2 centers, fluted 9 on the base 4, there is the projection 13 with groove 9 couplings described valve body 2 lower ends, projection 13 is an one with valve body 1, described valve pocket 11 outer surfaces have valve handle 7, and described base 4 is fixed on pot cover 8 centres, and work station 14 and exhaust station 15 are arranged on the pot cover 8, distance between described work station 14 and the exhaust station 15 equates that with valve handle 7 movable distance described valve handle 7 movable distance equate with the displacement of projection 13 between groove 9 and upper surface 10.Grab 2 is arranged, draw-in groove 5 couplings of described grab 2 and base 4 outers (when the mouth of pipe of spool 6 sealing blast pipes 3, grab 2 just in time is stuck in the draw-in groove 5, make seal the location more accurate) on the valve pocket 11.
