Description
Technical Field
The utility model is applied to the technical field of pressure cookers, and particularly relates to a multi-stage pressure regulating pressure release valve.
Background
The pressure relief valve of the pressure cooker is a valve body with constant weight, when the steam pressure in the cooker is larger than the weight of the valve body, the steam rushes out after the valve body is rushed out, so that the air pressure in the cooker is kept constant, the food materials are reasonably cooked, and the food materials become more delicious. The pressure in the pot required by cooking different food materials is different, but the prior pressure release valve can only control one pressure, so that the pressure in the pot can be controlled only by replacing valve bodies with other balance weights, the cost is increased due to too many types of required valve bodies, and the replacement operation is more complicated. If a multi-step pressure regulating relief valve which is simple in structure, simple and convenient to operate and capable of reducing cost can be designed, the problem can be well solved.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides the multi-stage pressure regulating relief valve which is simple in structure, simple and convenient to operate and capable of reducing cost.
The technical scheme adopted by the utility model is as follows: the pressure cooker comprises a handle, a valve core sleeve, a spring, a poke rod and an exhaust pipe, wherein the spring and the valve core are arranged in the valve core sleeve, the handle is connected with the valve core through the spring, the valve core is matched in a pipe orifice of the exhaust pipe, the exhaust pipe is arranged on a cooker cover of the pressure cooker, the poke rod penetrates through the handle and then is fixed on the valve core, a high-pressure groove, a medium-pressure groove and a low-pressure groove which are sequentially increased in height are arranged on the valve core sleeve, and the high-pressure groove, the medium-pressure groove and the low-pressure groove are communicated with each other and are matched with the poke rod.
Furthermore, the bottom of the valve core is conical, and the bottom of the valve core is matched in a pipe orifice of the exhaust pipe.
Further, the handle is sleeved on the top of the valve core sleeve, and the bottom of the valve core sleeve is in threaded fit with the exhaust pipe.
Further, a sealing ring is sleeved on the valve core.
Furthermore, the valve core sleeve is provided with a plurality of exhaust holes.
Further, the pressure release valve of multi-step pressure regulation still includes the nut, the nut sets up on the pot cover of pressure cooker, the blast pipe with nut screw-thread fit.
The utility model has the beneficial effects that: the bottom of the valve core is matched in the pipe orifice of the exhaust pipe under the action of the elastic force of the spring, so that sealing is formed, and certain air pressure is formed in the pressure cooker in the cooking process. When the air pressure in the cooker reaches a certain degree, the high-pressure steam is discharged from the exhaust pipe, and the valve core can move upwards under the pressure action of the high-pressure steam until the exhaust pipe is not sealed, so that the high-pressure steam can be smoothly discharged, and the air pressure in the cooker can meet the requirement of food materials.
When the poke rod is matched with the high-pressure groove, the spring is compressed maximally, namely the valve core is subjected to the maximum elastic force, so that the upward moving distance of the valve core under the action of the air pressure in the cooker is minimum, and the discharge amount of high-pressure steam is correspondingly reduced, so that the high air pressure in the cooker is maintained, and the requirement of food materials is met; similarly, the handle is pressed downwards, then the handle is rotated for a certain amplitude, the poke rod is positioned at a medium pressure position or a low pressure position, finally, the external force is cancelled, the valve core can move upwards under the action of the elastic force of the spring until the poke rod is matched in the medium pressure groove or the low pressure groove, at the moment, the upward moving distance of the valve core under the action of the air pressure in the cooker can be increased, the discharge amount of high-pressure steam can be correspondingly increased, and therefore the medium air pressure or the low air pressure can be maintained in the cooker, and the requirement of food materials is met.
Therefore, the pressure regulating device is simple in structure, simple and rapid in pressure regulating operation, and is divided into three air pressure control positions, namely a high air pressure control position, a medium air pressure control position and a low air pressure control position according to the compression degree of the spring so as to ensure that different food materials can obtain different air pressure effects, so that the requirements of the food materials are met, the food materials are reasonably cooked, and the pressure regulating device is more delicious and high in practicability.

Detailed Description
As shown in fig. 1 to 3, in this embodiment, the present invention includes a handle 1, a valve core 2, a valve core sleeve 3, a spring 4, a poking rod 5 and an exhaust pipe 6, wherein the spring 4 and the valve core 2 are both disposed in the valve core sleeve 3, the handle 1 is connected to the valve core 2 through the spring 4, the valve core 2 is adapted to a pipe orifice of the exhaust pipe 6, the exhaust pipe 6 is disposed on a lid of a pressure cooker, the poking rod 5 is fixed to the valve core 2 after passing through the handle 1, the valve core sleeve 3 is provided with a high pressure groove 7, a medium pressure groove 8 and a low pressure groove 9, which are sequentially increased in height, and the high pressure groove 7, the medium pressure groove 8 and the low pressure groove 9 are communicated with each other and are adapted to the poking rod 5.
In this embodiment, the bottom of the valve core 2 is conical, and the bottom of the valve core 2 is fitted in the pipe orifice of the exhaust pipe 6.
In this embodiment, the handle 1 is sleeved on the top of the valve core sleeve 3, and the bottom of the valve core sleeve 3 is in threaded fit with the exhaust pipe 6.
In this embodiment, the valve core 2 is sleeved with a sealing ring 10.
In this embodiment, the valve core sleeve 3 is provided with a plurality of exhaust holes 11.
