Referring to fig. 1 to 4, according to an embodiment of the present invention, there is provided a safety valve, which includes a valve body 10, a valve cover 20, a valve body assembly 30, and an elastic member 40.
The valve body 10 is provided with a mounting cavity 11 for facilitating mounting of the valve core assembly 30 and the elastic member 40. The first end of the valve body 10 is provided with an air inlet 12 communicated with the installation cavity 11, and the side wall of the valve body 10 is provided with an air outlet 13 communicated with the installation cavity 11; the valve cover 20 is provided at a second end of the valve body 10 opposite to the first end; the valve core assembly 30 is installed in the installation cavity 11 and can reciprocate in a direction from the first end to the second end of the valve body 10, and the valve core assembly 30 opens or closes the intake port 12 when reciprocating in the installation cavity 11.
The upper end of the valve core assembly 30 and the valve cover 20 are arranged to be mutually attracted to form a magnetic attraction structure, and when the attraction force between the magnetic attraction structures overcomes the elastic resistance of the elastic element 40, the valve core assembly 30 is driven to open the air inlet 12 so as to realize continuous exhaust.
In one embodiment of the invention, the valve core assembly 30 includes a valve core 31 and a magnetic member 32 disposed on the valve core 31, and the valve cover 20 is made of a solid material that can be absorbed by the magnetic member 32, and the magnetic absorbing structure includes the magnetic member 32 and the valve cover 20.
Of course, in other embodiments of the present invention, the magnetic member 32 may be disposed at the lower end of the valve cover 20, and the valve core assembly 30 may be made of a solid material that can be absorbed by the magnetic member 32, where the magnetic structure includes the magnetic member 32 and the valve core assembly 30.
The elastic element 40 is disposed in the installation cavity 11, and two ends of the elastic element 40 respectively abut against the valve core 31 and the valve cover 20, so that the valve core 31 can reciprocate in the installation cavity 11 under the action of the elastic element 40 and the magnetic piece 32.
Wherein, when the safety valve is closed, the elastic force exerted by the elastic element 40 on the valve core 31 is larger than the adsorption force between the magnetic attraction structures; when the safety valve is opened, the elastic force of the elastic element 40 applied to the valve core 31 is smaller than the adsorption force between the magnetic attraction structures, and the elastic element 40 cannot automatically reset, so that the safety valve can realize continuous exhaust.
As can be seen from the above-mentioned structure, when the safety valve of the present embodiment is used, the safety valve is mounted on other structures, such as a pressure cooker, and in this case, the safety valve is in a closed state, and the elastic force applied by the elastic element 40 to the valve core 31 is greater than the adsorption force of the magnetic element 32 to the valve cover 20, so that the valve core assembly 30 seals the air inlet 12. When steam in the pressure cooker enters the installation cavity 11 from the air inlet 12, the valve core assembly 30 is lifted along with the rising of air pressure, and the air inlet 12 is communicated with the air outlet 13, so that the exhausting function is realized. At this time, when the adsorption force between the magnetic member 32 and the valve cover 20 overcomes the elastic resistance of the elastic element 40, the magnetic member 32 is adsorbed on the valve cover 20 to drive the valve core assembly 30 to open the air inlet 12, so that the air inlet 12 and the air outlet 13 are kept in a communicated state, continuous air exhaust is realized, and the use stability of the safety valve is ensured.
It can be seen that in the process of decreasing the distance between the magnetic member 32 and the valve cover 20 in this embodiment, the increasing speed of the attraction force of the magnetic member 32 is faster than the increasing speed of the repulsive force of the elastic member 40. At the time of design, the initial distance between the magnetic member 32 and the valve cover 20 is calculated, and the repulsive force of the elastic member 40 is greater than the attractive force of the magnetic member 32. When the magnetic member 32 is attracted to the valve cover 20, the repulsive force of the elastic member 40 is smaller than the attraction force of the magnetic member 32.
Thus, since the attraction force of the magnetic member 32 is smaller than the repulsive force of the elastic member 40 at this time, the valve core assembly 30 acts downward to form a sealed state with the space below the valve body 10, and at this time, the safety valve is in an inactive state; when the pressure in the pressure cooker exceeds the set value, the safety valve is started to be in a working state, the valve core assembly 30 is pushed upwards by the air pressure in the pressure cooker, and the distance between the magnetic piece 32 and the valve cover 20 is continuously reduced; when the adsorption force of the magnetic member 32 is greater than the repulsive force of the elastic member 40, the magnetic member 32 drives the valve core assembly 30 to move upwards until the valve core assembly is adsorbed on the valve cover 20, and the valve core assembly cannot fall down, so that the exhaust state is maintained, and the purpose of continuous exhaust is achieved.
The magnetic attraction structure of this embodiment includes S-pole magnet and N-pole magnet that adsorb each other, and during the design, will S-pole magnet and N-pole magnet set up wantonly respectively in the lower extreme of valve gap 20 and the upper end of case subassembly 30.
The valve body 10 in this embodiment is a cylindrical structure, the installation cavity 11 is a circular cavity arranged along the center of the cylindrical structure, the number of air outlets 13 is plural, and the plurality of air outlets 13 are arranged along the circumference of the cylindrical structure, so that the air in the installation cavity 11 can be conveniently and rapidly discharged. Of course, the valve body 10 in the present embodiment may be provided in a square cylindrical structure, and the air outlet 13 may be provided in only one.
The valve cover 20 in the present embodiment is provided with a mounting hole 21, and the mounting hole 21 communicates with the mounting cavity 11; the valve body 31 includes a body portion 311 and a valve stem portion 312 provided on the body portion 311, and when installed, the valve stem portion 312 passes through the installation hole 21 and is exposed to the valve cover 20, and one end of the valve stem portion 312 exposed to the valve cover 20 is provided with the valve handle 50.
In general, the safety valve of the present invention is in a non-activated state, the elastic force applied by the elastic element 40 to the valve core 31 is greater than the adsorption force of the magnetic element 32 to the valve cover 20, so as to compress the valve core assembly 30, and further seal the air inlet 12, so that the safety valve is in a closed state. When the air pressure in the pressure cooker exceeds the set value, the valve core assembly 30 is pushed upwards by the air pressure in the pressure cooker, and the distance between the magnetic piece 32 and the valve cover 20 is continuously reduced; when the adsorption force of the magnetic part 32 is greater than the repulsive force of the elastic element 40, the magnetic part 32 drives the valve core assembly 30 to move upwards until being adsorbed on the valve cover 20, so that the valve core assembly cannot fall down, the exhaust state is maintained, the purpose of continuous exhaust is realized, the pressure in the cooker cannot rise again due to falling-back sealing of the valve core, and the use safety is ensured. When the valve handle 50 is needed to be reused, the valve core assembly 30 can be reset by pressing the valve handle 50 to move towards the direction close to the air inlet 12, in the process, the adsorption force exerted by the magnetic element 32 on the valve cover 20 is reduced, the elastic force exerted by the elastic element 40 on the valve core 31 is larger than the adsorption force exerted by the magnetic element 32 on the valve cover 20, the valve core assembly 30 is conveniently pressed, the air inlet 12 is blocked, and the safety valve is in a closed state.
