[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In the description of the embodiments of the present application, it should be understood that the orientation or positional relationship indicated by the terms "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. The term "connection" in this application, unless otherwise specified, mainly refers to a physical structural connection, and may also include meanings such as direct connection or indirect connection when specified. The terms "first" and "second" in the specification and claims of this application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the term "includes" and any variations thereof are intended to cover non-exclusive inclusions.

[0029] Please also read Figure 1 and Figure 2 , Figure 1 is a three-dimensional schematic diagram of the exhaust valve 1 in the embodiment of the present application, Figure 2 for Figure 1 A three-dimensional schematic diagram of the exhaust valve 1 without the valve 11.

[0030] like Figure 1 and Figure 2 As shown, the exhaust valve 1 includes a valve body 12, a valve 11 and an electromagnetic telescopic assembly 13. The valve 11 is movably connected to the valve body 12 along the thickness direction 19 of the valve body 12. The electromagnetic telescopic assembly 13 is installed on the valve body 12 at a position adjacent to the valve 11. The electromagnetic telescopic assembly 13 is used to pop out when controlled to push the valve 11 along the thickness direction 19 of the valve body 12 to open the valve 11.

[0031] Thus, the electromagnetic telescopic component 13 can automatically pop out when controlled to open the valve 11, and the electromagnetic telescopic component 13 can also automatically retract so as not to affect the closing of the valve 11, making the opening and closing of the valve 11 more flexible and convenient, and the valve 11 can be opened in time in an emergency, thereby improving the reliability of the exhaust valve 1.

[0032] The electromagnetic telescopic component 13 pops out when controlled, including: the electromagnetic telescopic component 13 pops out when powered on to receive electric energy, or the electromagnetic telescopic component 13 pops out when receiving a control signal.

[0033] The fact that the valve 11 is movably connected to the valve body 12 along the thickness direction 19 means that the valve 11 is movable in the thickness direction 19 , and does not limit the connection method.

[0034] In some embodiments, Figure 1 and Figure 2As shown, the valve body 12 is provided with an opening 18, and the electromagnetic telescopic component 13 is connected to the side 121 at the intersection of the valve body 12 and the opening 18 to be fixed to the valve body 12, wherein the valve 11 is movably connected to one end of the opening 18 along the thickness direction 19, and the electromagnetic telescopic component 13 pops up when powered on to open the valve 11 along the thickness direction 19, wherein the one end of the valve 11 movably connected to the opening 18 along the thickness direction 19 means that the valve 11 is movable in the thickness direction 19, and the connection method is not limited.

[0035] In some embodiments, the exhaust valve 1 can be used in some closed containers or closed spaces. Through the exhaust valve 1 of the present application, the valve 11 can be opened in time in an emergency to allow the gas in the closed container or closed space to circulate with the outside world, thereby improving safety.

[0036] Wherein, the electromagnetic telescopic component 13 can be a through-type DC push-pull electromagnet. The through-type DC push-pull electromagnet includes a movable iron core, a coil and a spring. The movable iron core is inserted into the coil. When the coil is energized, a magnetic field is generated around the movable iron core. The thrust generated by the magnetic field causes the movable iron core to be pushed out, thereby pushing the valve 11 and opening the valve 11. When the coil is de-energized, the thrust disappears as the magnetic field disappears. At this time, the movable iron core automatically resets by relying on the spring. It should be noted that the through-type DC push-pull electromagnet cannot be energized for a long time. If the through-type DC push-pull electromagnet is energized for a long time, it will cause the temperature to rise and burn the coil.

[0037] It is understandable that the electromagnetic telescopic component 13 being a through-type DC push-pull electromagnet is only an example, and the electromagnetic telescopic component 13 can be but is not limited to a through-type DC push-pull electromagnet, as long as it can push the valve 11 open, and no limitation is made here.

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the exhaust valve 1 further includes an electromagnetic adsorption component 14 , which is installed on the valve body 12 , and is used for magnetically adsorbing the valve 11 to fix the valve 11 when powered on.

[0039] Therefore, the electromagnetic adsorption component 14 can automatically fix the valve 11 to close the valve 11, thereby reducing human resources and reducing labor costs.

[0040] In some embodiments, the electromagnetic adsorption component 14 may be a DC suction cup electromagnet. The valve 11 may be made of a magnetic material, such as metal. When the coil of the DC suction cup electromagnet is energized, a magnetic field is generated around the iron core in the coil, and the magnetic force generated by the magnetic field can cause the valve 11 to be attracted to fix the valve 11; when the coil is de-energized, the magnetic force disappears along with the disappearance of the magnetic field, and the valve 11 will not be fixed to the valve body 12 by the DC suction cup electromagnet.

[0041] It is understandable that the electromagnetic adsorption component 14 being a DC suction cup type electromagnet is just an example, and the electromagnetic adsorption component 14 can be but is not limited to a DC suction cup type electromagnet, which is not limited here.

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the exhaust valve 1 also includes a switch sensor 15, which is installed on the valve body 12. The switch sensor 15 is used to detect the state of the valve 11, and the state of the valve 11 includes an open state of the valve 11 and a closed state of the valve 11. The electromagnetic telescopic component 13 is at least used to power on when the valve 11 is in a closed state, and the electromagnetic adsorption component 14 is at least used to power on when the valve 11 is in an open state.

[0043] Thus, the electromagnetic telescopic component 13 and the electromagnetic adsorption component 14 can respectively open and close the valve 11 in corresponding states according to the state of the valve 11 detected by the switch sensor 15, so as to automatically control the opening and closing of the valve 11.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, the electromagnetic telescopic assembly 13 includes a first electromagnetic telescopic assembly 131 and a second electromagnetic telescopic assembly 132 , and at least one of the first electromagnetic telescopic assembly 131 and the second electromagnetic telescopic assembly 132 pops out when powered on to push the valve 11 to open the valve 11 .

[0045] Therefore, the exhaust valve 1 is provided with the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 which can pop out more accurately and timely to push the valve 11 to open the valve 11, and the electromagnetic telescopic component 13 is designed redundantly to avoid the electromagnetic telescopic component 13 from failing to open the valve 11, thereby improving the reliability of the exhaust valve 1.

[0046] In some embodiments, Figure 1 and Figure 2As shown, the first electromagnetic telescopic component 131 includes a first electromagnetic telescopic part 1311 and a second electromagnetic telescopic part 1312, and the second electromagnetic telescopic component 132 includes a third electromagnetic telescopic part 1321 and a fourth electromagnetic telescopic part 1322. The third electromagnetic telescopic part 1321 is arranged between the first electromagnetic telescopic part 1311 and the second electromagnetic telescopic part 1312, and the second electromagnetic telescopic part 1312 is arranged between the third electromagnetic telescopic part 1321 and the fourth electromagnetic telescopic part 1322. This staggered arrangement can expand the force range of the valve 11, and enable the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 to better open the valve 11.

[0047] It is understandable that the number and arrangement of the electromagnetic telescopic components 13 can be set according to actual needs and are not limited here.

[0048] In some embodiments, the valve 11 of the exhaust valve 1 can also open in response to other external forces when the electromagnetic telescopic component 13 is powered off.

[0049] Therefore, the exhaust valve 1 can be actively opened by the electromagnetic telescopic component 13 when power is on, and can also be passively opened by other external forces when power is off, thereby improving the reliability of the valve 11 in extreme situations.

[0050] It is understandable that other external forces may be but are not limited to the pressure generated by the combustible gas, which is not limited here.

[0051] Among them, Figure 1 and Figure 2 As shown, the electromagnetic adsorption component 14 includes a first electromagnetic adsorption component 141 and a second electromagnetic adsorption component 142 .

[0052] Therefore, the exhaust valve 1 is provided with the first electromagnetic adsorption component 141 and the second electromagnetic adsorption component 142 so as to more firmly fix the valve 11. The redundant design of the electromagnetic adsorption component 14 can avoid the electromagnetic adsorption component 14 from failing to fix the valve 11, thereby improving the reliability of the exhaust valve 1.

[0053] In some embodiments, Figure 2 As shown, the first electromagnetic adsorption component 141 and the second electromagnetic adsorption component 142 are located in the middle of the valve body 12 . This arrangement allows the first electromagnetic adsorption component 141 and the second electromagnetic adsorption component 142 to better fix the valve 11 .

[0054] It is understandable that the number and position of the electromagnetic adsorption components 14 can be set according to actual needs and are not limited here.

[0055] In some embodiments, Figure 1 and Figure 2 As shown, the switch sensor 15 may include a first switch sensor 151 and a second switch sensor 152. The first switch sensor 151 and the second switch sensor 152 are NPN-NC (Negative Positive Negative-Normal Close, normally closed diode) type bipolar Hall proximity switch sensors. When the valve 11 is detected to be in an open state, the switch of the NPN-NC type bipolar Hall proximity switch sensor remains in a closed state, and the output end is a low level; when the valve 11 is detected to be in a closed state, the switch is disconnected, and the output end is a high level.

[0056] It can be understood that the first switch sensor 151 and the second switch sensor 152 can also be NPN-NO (Negative Positive Negative-Normal Open, normally open diode) type bipolar Hall proximity switch sensors, etc., as long as they can detect the state of the valve 11; and the switch sensor 15 is redundantly designed to make the detection result of the switch sensor 15 more reliable, wherein the number of the switch sensors 15 can be set according to actual needs and is not limited here.

[0057] In some embodiments, the exhaust valve 1 further includes a sealing ring, which is disposed on a side edge 121 of the valve 11 , so that the valve 11 can be more firmly fixed to the valve body 12 .

[0058] In some embodiments, Figure 1 As shown, the connecting member 16 is connected between the valve 11 and the valve body 12 to prevent the valve 11 from falling to the ground when being pushed open by the electromagnetic telescopic assembly 13 .

[0059] It is understandable that the connecting member 16 can be, but is not limited to, a chain, as long as it can ensure that the valve 11 does not fall off when it is opened, and no limitation is made here.

[0060] In some embodiments, Figure 1 and Figure 2 As shown, the exhaust valve 1 further includes a connecting plate 17 , which is disposed at the opening 18 and connected to the valve body 12 , and the electromagnetic adsorption component 14 and the switch sensor 15 can be installed on the connecting plate 17 .

[0061] Please also read Figure 3 , Figure 3: is an overall schematic diagram of the control circuit 2 in the embodiment of the present application. The control circuit 2 is used to control the exhaust valve 1, wherein the exhaust valve 1 can be the exhaust valve 1 in any of the aforementioned embodiments. As mentioned above, the exhaust valve 1 includes a valve body 12, a valve 11 and an electromagnetic telescopic component 13, wherein the valve 11 is movably connected to the valve body 12, and the electromagnetic telescopic component 13 is installed at a position adjacent to the valve 11 on the valve body 12, and the electromagnetic telescopic component 13 is used to pop out when controlled to open the valve 11 along the thickness direction 19 of the valve body 12. Figure 3 As shown, the control circuit 2 includes a power supply 21 and a relay group 22. The relay group 22 is connected between the power supply 21 and the electromagnetic telescopic component 13, and is used to output the electric energy provided by the power supply 21 to the electromagnetic telescopic component 13 so that the electromagnetic telescopic component 13 pops out, or stop outputting the electric energy provided by the power supply 21 to the electromagnetic telescopic component 13 so that the electromagnetic telescopic component 13 retracts or maintains a retracted state.

[0062] Thus, the relay group 22 can make the electromagnetic telescopic assembly 13 pop out to automatically open the valve 11; and the relay group 22 can make the valve 11 reach the state of the valve 11 required by the operator under different conditions, thereby improving the reliability and flexibility of the exhaust valve 1. The power supply 21 is a DC 24-36V.

[0063] In some embodiments, Figure 1 and Figure 3 As shown, as mentioned above, the exhaust valve 1 also includes an electromagnetic adsorption component 14, which is installed on the valve body 12, and the electromagnetic adsorption component 14 is used to magnetically adsorb the valve 11 to fix the valve 11 when powered on. The relay group 22 is also connected between the power supply 21 and the electromagnetic adsorption component 14, and is used to output the electric energy provided by the power supply 21 to the electromagnetic adsorption component 14 so that the electromagnetic adsorption component 14 adsorbs the valve 11, or stops outputting the electric energy provided by the power supply 21 to the electromagnetic adsorption component 14 so that the electromagnetic adsorption component 14 stops adsorbing the valve 11.

[0064] Thus, the relay group 22 can enable the electromagnetic adsorption component 14 to adsorb the valve 11 so as to close the valve 11 more firmly; and the relay group 22 can enable the valve 11 to reach the valve 11 state required by the operator under different conditions, thereby improving the reliability and flexibility of the exhaust valve 1.

[0065] In some embodiments, Figure 3As shown, as also mentioned above, the electromagnetic telescopic component 13 may include a first electromagnetic telescopic component 131 and a second electromagnetic telescopic component 132, at least one of the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 pops out when powered on to push the valve 11 to open the valve 11; the power supply 21 includes a first power supply 211 and a second power supply 212, the relay group 22 includes a first relay 221 and a second relay 222, the first relay 221 is connected between the first power supply 211 and the first electromagnetic telescopic component 131, and is used to output the electric energy provided by the first power supply 211 to the first electromagnetic telescopic component 131, so as to open the valve 11; The first electromagnetic telescopic component 131 is made to pop out, or the power provided by the first power supply 211 is stopped from being output to the first electromagnetic telescopic component 131, so that the first electromagnetic telescopic component 131 is retracted or maintained in a retracted state; the second relay 222 is connected between the second power supply 212 and the second electromagnetic telescopic component 132, and is used to output the power provided by the second power supply 212 to the second electromagnetic telescopic component 132, so that the second electromagnetic telescopic component 132 is popped out, or the power provided by the second power supply 212 is stopped from being output to the second electromagnetic telescopic component 132, so that the second electromagnetic telescopic component 132 is retracted or maintained in a retracted state.

[0066] Thus, the first relay 221 is powered by the first power supply 211 to make the first electromagnetic telescopic component 131 pop out, retract or maintain a retracted state, and the second relay 222 is powered by the second power supply 212 to make the second electromagnetic telescopic component 132 pop out, retract or maintain a retracted state, that is, the control elements and power supply elements of the control circuit 2 are designed redundantly, so that the control circuit 2 can more accurately and timely control the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 to pop out to push open the valve 11, avoiding the first relay 221 or the second relay 222, the first power supply 211 or the second power supply 212 from being unable to open the valve 11 due to a fault, thereby improving the reliability of the exhaust valve 1.

[0067] In some embodiments, Figure 3As shown, the relay group 22 also includes a third relay 223, which is connected between the first power supply 211 and the first relay 221, and also connected between the second power supply 212 and the second relay 222. The third relay 223 is used to output the electric energy provided by the first power supply 211 to the first relay 221 or stop outputting the electric energy provided by the first power supply 211 to the first relay 221, and is used to output the electric energy provided by the second power supply 212 to the second relay 222 or stop outputting the electric energy provided by the second power supply 212 to the second relay 222.

[0068] Thus, the third relay 223 enables the control circuit 2 to more accurately control the first electromagnetic telescopic component 131 and / or the second electromagnetic telescopic component 132 to pop out to push open the valve 11, thereby preventing the first relay 221 or the second relay 222 from mistakenly opening the valve 11 due to a malfunction, thereby improving the reliability and flexibility of the exhaust valve 1.

[0069] In some embodiments, Figure 1 and Figure 3 As shown, when the power is off, the third relay 223 outputs the electric energy provided by the first power supply 211 to the first relay 221, and outputs the electric energy provided by the second power supply 212 to the second relay 222. When the power is on, the third relay 223 stops outputting the electric energy provided by the first power supply 211 to the first relay 221, and outputs the electric energy provided by the second power supply 212 to the second relay 222; the control circuit 2 also includes a control switch 23, and the control switch 23 and the third relay 223 are connected in series between the first power supply 211 and the ground. When the control switch 23 is turned on, the third relay 223 is powered on and works, and when the control switch 23 is turned off, the third relay 223 is powered off.

[0070] Thus, the control logic of the control circuit 2 is simplified, and only one dry contact signal is needed to control the state of the valve 11. When power is supplied, as long as the control switch 23 is not closed, the valve 11 is in an open control state, thereby improving the working efficiency and flexibility of the exhaust valve 1.

[0071] In some embodiments, Figure 3As shown, the first relay 221 includes a first normally closed switch group 2211, the second relay 222 includes a second normally closed switch group 2221, and the third relay 223 includes a third normally closed switch group 2231, wherein the first normally closed switch group 2211 is closed when the first relay 221 is powered off, and is disconnected when the first relay 221 is powered on, the second normally closed switch group 2221 is closed when the second relay 222 is powered off, and is disconnected when the second relay 222 is powered on, and the third normally closed switch group 2231 is closed when the third relay 223 is powered off, and is disconnected when the third relay 223 is powered on. The first normally closed switch group 2211 is connected between the third normally closed switch group 2231 and the first electromagnetic telescopic component 131, and the second normally closed switch group 2221 is connected between the third normally closed switch group 2231 and the second electromagnetic telescopic component 132; wherein, when the third normally closed switch group 2231 is closed and the first normally closed switch group 2211 is also closed, the electric energy provided by the first power supply 211 is output to the first electromagnetic telescopic component 131 through the third normally closed switch group 2231 and the first normally closed switch group 2211, so that the first electromagnetic telescopic component 131 pops out; when the third normally closed switch group 2231 is closed and the second normally closed switch group 2221 is also closed, the electric energy provided by the second power supply 212 is output to the second electromagnetic telescopic component 132 through the third normally closed switch group 2231 and the second normally closed switch group 2221, so that the second electromagnetic telescopic component 132 pops out.

[0072] Thus, the operator can control the states of the first normally closed switch group 2211, the second normally closed switch group 2221 and the third normally closed switch group 2231 to control the pop-up of the first electromagnetic telescopic assembly 131 and the second electromagnetic telescopic assembly 132, so that the exhaust valve 1 automatically opens the valve 11 under the logical control of the control circuit 2, thereby improving the flexibility of the exhaust valve 1 and reducing human resources to reduce labor costs.

[0073] In some embodiments, Figure 3As shown, the third normally closed switch group 2231 includes a first normally closed switch 2232 and a second normally closed switch 2233, wherein the first normally closed switch 2232 is connected between the first power supply 211 and the first normally closed switch group 2211, and the second normally closed switch 2233 is connected between the second power supply 212 and the second normally closed switch group 2221; wherein, when the first normally closed switch 2232 is closed and the first normally closed switch group 2211 is also closed, the electric energy provided by the first power supply 211 is output to the first electromagnetic telescopic component 131 through the first normally closed switch 2232 and the first normally closed switch group 2211, so that the first electromagnetic telescopic component 131 pops out; when the second normally closed switch 2233 is closed and the second normally closed switch group 2221 is also closed, the electric energy provided by the second power supply 212 is output to the second electromagnetic telescopic component 132 through the second normally closed switch 2233 and the second normally closed switch group 2221, so that the second electromagnetic telescopic component 132 pops out.

[0074] Among them, Figure 1 and Figure 3 As shown, the sub-switches of the first normally closed switch group 2211 and the second normally closed switch group 2221 are respectively connected to the first electromagnetic telescopic component 1311 and the second electromagnetic telescopic component 1312 of the first electromagnetic telescopic assembly 131 and the third electromagnetic telescopic component 1321 and the fourth electromagnetic telescopic component 1322 of the second electromagnetic telescopic assembly 132, so as to perform redundant design on switch elements and functional elements, thereby improving the reliability of the exhaust valve 1. It can be understood that the number of sub-switches of the first normally closed switch group 2211 and the second normally closed switch group 2221 and the connection method of connecting the first electromagnetic telescopic assembly 131 and the second electromagnetic telescopic assembly 132 can be set according to actual needs, and are not limited here.

[0075] In some embodiments, Figure 3 As shown, the third relay 223 also includes a first normally open switch group 2234, which is opened when the third relay 223 is powered off, and closed when the third relay 223 is powered on; the first normally open switch group 2234 is connected between the first power supply 211 and the electromagnetic adsorption component 14, and the first normally open switch group 2234 is used to output the electric energy provided by the first power supply 211 to the electromagnetic adsorption component 14 when closed, so that the electromagnetic adsorption component 14 adsorbs the valve 11, and is used to stop outputting the electric energy provided by the first power supply 211 to the electromagnetic adsorption component 14 when disconnected, so that the electromagnetic adsorption component 14 stops adsorbing the valve 11.

[0076] Therefore, the first normally open switch group 2234 controls the working state of the electromagnetic adsorption component 14 according to its own logic, so that the exhaust valve 1 can more firmly fix the valve 11 under the logic control of the control circuit 2, thereby improving the reliability of the exhaust valve 1.

[0077] The sub-switches of the first normally open switch group 2234 are respectively connected to the first electromagnetic adsorption component 141 and the second electromagnetic adsorption component 142 of the electromagnetic adsorption component 14, so as to perform redundant design on the switch elements and functional elements, thereby improving the reliability of the exhaust valve 1. It can be understood that the number of sub-switches of the first normally open switch group 2234 and the connection method of connecting the electromagnetic adsorption component 14 can be set according to actual needs, and are not limited here.

[0078] The first relay 221 further includes a first electromagnet 2213. When the first coil of the first electromagnet 2213 is powered on, a magnetic field is generated around the first iron core of the first electromagnet 2213, so that the first normally closed switch group 2211 is opened; when the first coil of the first electromagnet 2213 is powered off, the magnetic field generated around the first iron core of the first electromagnet 2213 disappears, so that the first normally closed switch group 2211 is closed.

[0079] The second relay 222 further includes a second electromagnet 2223. When the second coil of the second electromagnet 2223 is powered on, a magnetic field is generated around the second iron core of the second electromagnet 2223, so that the second normally closed switch group 2221 is opened; when the second coil of the second electromagnet 2223 is powered off, the magnetic field generated around the second iron core of the second electromagnet 2223 disappears, so that the second normally closed switch group 2221 is closed.

[0080] The third relay 223 also includes a third electromagnet 2235. When the third coil of the third electromagnet 2235 is energized, a magnetic field is generated around the third iron core of the third electromagnet 2235, so that the third normally closed switch group 2231 is disconnected and the first normally open switch group 2234 is closed; when the third coil of the third electromagnet 2235 is de-energized, the magnetic field generated around the third iron core of the third electromagnet 2235 disappears, so that the third normally closed switch group 2231 is closed and the first normally open switch group 2234 is disconnected.

[0081] In other embodiments, Figure 3As shown, the relay group 22 further includes a fourth relay 224, the fourth relay 224 is connected to the third relay 223, and the third relay 223 is used to output the electric energy provided by the first power source 211 to the fourth relay 224 or stop outputting the electric energy provided by the first power source 211 to the fourth relay 224. When the third relay 223 is powered on, the electric energy provided by the first power source 211 is output to the fourth relay 224, and when the third relay 223 is powered off, the electric energy provided by the first power source 211 is stopped from being output to the fourth relay 224.

[0082] In some embodiments, Figure 3 As shown, the fourth relay 224 includes a second normally open switch group 2241, which is disconnected when the fourth relay 224 is powered off, and closed when the fourth relay 224 is powered on. The second normally open switch group 2241 is connected between the first normally open switch group 2234 and the electromagnetic adsorption component 14, wherein when the second normally open switch group 2241 is closed and the first normally open switch group 2234 is also closed, the electric energy provided by the first power supply 211 is output to the electromagnetic adsorption component 14 through the second normally open switch group 2241 and the first normally open switch group 2234, so that the electromagnetic adsorption component 14 adsorbs the valve 11, and when disconnected, the electric energy provided by the first power supply 211 is stopped from being output to the electromagnetic adsorption component 14, so that the electromagnetic adsorption component 14 stops adsorbing the valve 11.

[0083] Thus, the second normally open switch group 2241 can prevent the first normally open switch group 2234 from being falsely triggered due to adhesion, which is equivalent to connecting one more controllable switch in series on the control loop, so that the electromagnetic adsorption component 14 can be triggered more accurately, thereby improving the reliability of the exhaust valve 1.

[0084] The sub-switches of the second normally open switch group 2241 are respectively connected to the first electromagnetic adsorption component 141 and the second electromagnetic adsorption component 142, so as to perform redundant design on the switch elements and functional elements, thereby improving the reliability of the exhaust valve 1. It can be understood that the number of sub-switches of the second normally open switch group 2241 and the connection method of the electromagnetic adsorption component 14 can be set according to actual needs, and are not limited here.

[0085] In some other embodiments, the second normally open switch group 2241 is directly connected between the first power supply 211 and the electromagnetic adsorption component 14, and the second normally open switch group 2241 is used to output the electric energy provided by the first power supply 211 to the electromagnetic adsorption component 14 when closed, so that the electromagnetic adsorption component 14 adsorbs the valve 11, and is used to stop outputting the electric energy provided by the first power supply 211 to the electromagnetic adsorption component 14 when disconnected, so that the electromagnetic adsorption component 14 stops adsorbing the valve 11.

[0086] It can be understood that the connection mode of the second normally open switch group 2241 can be set according to actual needs and is not limited here.

[0087] Among them, the fourth relay 224 also includes a fourth electromagnet 2242. When the fourth coil of the fourth electromagnet 2242 is energized, a magnetic field is generated around the fourth iron core of the fourth electromagnet 2242, so that the second normally open switch group 2241 is closed; when the fourth coil of the fourth electromagnet 2242 is de-energized, the magnetic field generated around the fourth iron core of the fourth electromagnet 2242 disappears, so that the second normally open switch group 2241 is opened.

[0088] In some embodiments, the control circuit 2 further includes a controller 25, the controller 25 is used to output a control signal to the control switch 23 to control the on and off of the control switch 23; the controller 25 is also used to collect the state of the first relay 221 and / or the second relay 222, the controller 25 determines the abnormality of the first power supply 211 and / or the second power supply 212 according to the collected state of the first relay 221 and / or the second relay 222, and controls to give a prompt when the abnormality is determined. Wherein, the controller 25 can be connected to a display screen (not shown in the figure) and / or an audio output device (not shown in the figure), and when the controller 25 determines the abnormality, it can control the display screen to display corresponding prompt information, and / or control the audio output device to output voice prompt information.

[0089] Thus, the control logic of the exhaust valve 1 is simplified. When power is supplied, the controller 25 only needs to control one dry node to put the valve 11 in an open control state. Moreover, the controller 25 can also detect the state of the valve 11 and the abnormality of the power supply 21 according to its own set logic, so that the operator can know the state of the valve 11 and whether the exhaust valve 1 has a fault in time even in remote operation, so as to perform timely maintenance and improve the reliability of the exhaust valve 1.

[0090] In some embodiments, Figure 3As shown, the first relay 221 further includes a third normally open switch group 2212, which is opened when the first relay 221 is powered off and closed when the first relay 221 is powered on; the second relay 222 further includes a fourth normally closed switch group 2222, which is closed when the second relay 222 is powered off and opened when the second relay 222 is powered on. The controller 25 determines the working state of the first relay 221 and the second relay 222 by detecting the switch node states of the third normally open switch group 2212 and the fourth normally closed switch group 2222, so that the controller 25 can detect the state of the valve 11 and whether the first power supply 211 and the second power supply 212 are abnormal according to the switch logic set by itself.

[0091] Among them, Figure 3 As shown, the third normally open switch group 2212 and the fourth normally closed switch group 2222 are each provided with two sub-switches so that the detection result of the controller 25 is more accurate. It is understandable that the number of sub-switches of the third normally open switch group 2212 and the fourth normally closed switch group 2222 can be set according to actual needs; and the controller 25 can also determine the state of the valve 11 and whether the first power supply 211 and the second power supply 212 are abnormal by detecting the voltage across the first normally closed switch group 2211 and the second normally closed switch group 2221, which is not limited here.

[0092] In some embodiments, Figure 3As shown, when the first relay 221 is powered off, the electric energy provided by the first power supply 211 is output to the first electromagnetic telescopic component 131, and when the first relay 221 is powered on, the electric energy provided by the first power supply 211 is stopped from being output to the first electromagnetic telescopic component 131; when the second relay 222 is powered off, the electric energy provided by the second power supply 212 is output to the second electromagnetic telescopic component 132, and when the second relay 222 is powered on, the electric energy provided by the second power supply 212 is stopped from being output to the second electromagnetic telescopic component 132; the exhaust valve further includes a switch sensor 15, and the switch sensor 15 includes a first switch sensor 151 and a second switch sensor 152. The first switch sensor 151 and the first relay 221 are connected in series between the first power supply 211 and the ground. The first switch sensor 151 is used to be turned on when the valve 11 is not detected, so that the first relay 221 is powered on, or disconnected when the valve 11 is detected, so that the first relay 221 is powered off; the second switch sensor 152 and the second relay 222 are connected in series between the second power supply 212 and the ground. The second switch sensor 152 is used to be turned on when the valve 11 is not detected, so that the second relay 222 is powered on, or disconnected when the valve 11 is detected, so that the second relay 222 is powered off.

[0093] Thus, the first switch sensor 151 can control the power on and off of the first relay 221 according to the state of the valve 11, so as to control the pop-up, retraction or maintenance of the retracted state of the first electromagnetic telescopic component 131. The second switch sensor 152 can control the power on and off of the second relay 222 according to the state of the valve 11, so as to control the pop-up, retraction or maintenance of the retracted state of the second electromagnetic telescopic component 132. The state of the valve 11 can be directly monitored to automatically open the valve 11, thereby improving the intelligence of the exhaust valve 1.

[0094] When the third relay 223 is connected between the first power source 211 and the first relay 221, the first relay 221 outputs the electric energy provided by the first power source 211 to the first electromagnetic telescopic component 131, so that the first electromagnetic telescopic component 131 pops out, which means that the third relay 223 is powered off and outputs the electric energy provided by the first power source 211 to the first relay 221, and then the first relay 221 outputs the electric energy provided by the first power source 211 to the first electromagnetic telescopic component 131 when the power is off. When the first relay 221 is powered on, the electric energy provided by the first power source 211 is stopped from being output to the first electromagnetic telescopic component 131. At this time, regardless of whether the third relay 223 outputs the electric energy provided by the first power source 211 to the first relay 221, the electric energy provided by the first power source 211 will not be output to the first electromagnetic telescopic component 131.

[0095] When the third relay 223 is connected between the second power source 212 and the second relay 222, the second relay 222 outputs the electric energy provided by the second power source 212 to the second electromagnetic telescopic component 132, so that the second electromagnetic telescopic component 132 pops out, which means that the third relay 223 is powered off, and the electric energy provided by the second power source 212 is output to the second relay 222, and then the second relay 222 outputs the electric energy provided by the second power source 212 to the second electromagnetic telescopic component 132 when the power is off. When the second relay 222 is powered on, the electric energy provided by the second power source 212 is stopped from being output to the second electromagnetic telescopic component 132. At this time, regardless of whether the third relay 223 outputs the electric energy provided by the second power source 212 to the second relay 222, the electric energy provided by the second power source 212 will not be output to the second electromagnetic telescopic component 132.

[0096] In some embodiments, Figure 3 As shown, the control circuit 2 further includes a protection module 24 , which is connected to the relay group 22 . The protection module 24 is used to release the energy generated when the relay group 22 is powered off to protect the relay group 22 .

[0097] Therefore, the protection module 24 can prevent the electromagnetic coil from being burned out by the over-voltage generated when the relay group 22 is powered off; and the protection module 24 protects the switch elements in the control circuit 2 from being broken down or burned out by the induced voltage.

[0098] In some embodiments, Figure 3As shown, the protection module 24 includes a first diode 241, a second diode 242, a third diode 243 and a fourth diode 244, the first diode 241 is reversely connected in parallel to the two ends of the first electromagnet 2213, the second diode 242 is reversely connected in parallel to the two ends of the second electromagnet 2223, the third diode 243 is reversely connected in parallel to the two ends of the third electromagnet 2235, and the fourth diode 244 is reversely connected in parallel to the two ends of the fourth electromagnet 2242; when the first electromagnet 2213, the second electromagnet 2223, the third electromagnet 2235 and the fourth electromagnet 2242 are powered off, they all generate a reverse high electromotive force due to the energy storage characteristics, and the electromotive force may exceed the withstand voltage of the switch element, causing breakdown or damage. At this time, the first diode 241, the second diode 242, the third diode 243 and the fourth diode 244 can provide a discharge circuit to consume the high electromotive force in the form of current, thereby protecting the switch element.

[0099] See also Figure 4 , Figure 4 Schematic diagram of an exhaust valve system 200 in an embodiment of the present application. The exhaust valve system 200 comprises an exhaust valve 1 in any of the aforementioned embodiments and a control circuit 2 in any of the aforementioned embodiments.

[0100] Thus, the exhaust valve system 200 enables the control circuit 2 to control the exhaust valve 1 to automatically control the opening and closing of the valve 11 of the exhaust valve 1, thereby saving human resources and reducing labor costs.

[0101] The specific structures of the exhaust valve 1 and the control circuit 2 are described above and will not be repeated here.

[0102] See also Figure 5 and Figure 6 , Figure 5 is an overall schematic diagram of the energy storage system 100 in an embodiment of the present application, Figure 6 1 is a three-dimensional schematic diagram of an energy storage system 100 in an embodiment of the present application. The energy storage system 100 includes an energy storage module 3 and the aforementioned exhaust valve system 200, wherein the energy storage module 3 is used to store electrical energy, the energy storage module 3 includes a housing 31, and the exhaust valve 1 of the exhaust valve system 200 is disposed in the housing 31 of the energy storage module 3.

[0103] Thus, the energy storage module 3 stores electrical energy for the operation of the equipment, and the exhaust valve 1 is arranged on the shell 31, so that when combustible gas appears in the energy storage module 3, the valve 11 can be opened and released in time, thereby improving the safety of the energy storage system 100.

[0104] The aforementioned display screen and / or audio output device may be an external device external to the energy storage system 100 , or may be a structure disposed on the housing 31 of the energy storage module 3 .

[0105] The control method of the energy storage system 100 is as follows:

[0106] Closing the valve 11: When the valve 11 is in the open state, neither the first switch sensor 151 nor the second switch sensor 152 detects the valve 11, so the first switch sensor 151 and the second switch sensor 152 are turned on, so that the first relay 221 and the second relay 222 are powered on, and the first normally closed switch group 2211 and the second normally closed switch group 2221 are both disconnected, so that the first relay 221 stops outputting the electric energy provided by the first power supply 211 to the first electromagnetic telescopic component 131, and the second relay 222 stops outputting the electric energy provided by the second power supply 212 to the second electromagnetic telescopic component 132. At this time, the operator outputs a valve closing control command at the controller 25 end, and the control switch 23 receives the valve closing control command to close, so that the third relay 223 and the fourth relay 224 are powered on, and the first normally closed switch 2232 and the second normally closed switch 2233 of the third normally closed switch group 2231 are powered on. The first normally open switch group 2234 and the second normally open switch group 2241 are both disconnected, and the first normally open switch group 2234 and the second normally open switch group 2241 are closed, so that the electric energy provided by the first power supply 211 is output to the electromagnetic adsorption component 14 to generate magnetic force, and the valve 11 is manually reset so that the valve 11 is fixed to the valve body 12 by the electromagnetic adsorption component 14 under the action of the magnetic force. At this time, even if the first switch sensor 151 and the second switch sensor 152 detect the valve 11 and disconnect the first switch sensor 151 and the second switch sensor 152 to cut off the power to the first relay 221 and the second relay 222, the controller 25 does not stop outputting the valve closing control command, and the control switch 23 is still in a closed state, so that the first normally closed switch 2232 and the second normally closed switch 2233 are still in an open state, so that the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 cannot pop out to push the valve 11 to open the valve 11, and the valve 11 remains in a closed state.

[0107] At the same time, the controller 25 detects that the node state of the third normally open switch group 2212 is in the disconnected state, and the node state of the fourth normally closed switch group 2222 is in the closed state. The controller 25 can determine the state of the valve 11 detected by the first switch sensor 151 and the second switch sensor 152 according to the set logic to determine that the valve 11 is in the closed state.

[0108] Open the valve 11: When the first power supply 211 and the second power supply 212 are both powered normally, and the valve 11 is in a closed state, the first switch sensor 151 and the second switch sensor 152 both detect the valve 11, so the first switch sensor 151 and the second switch sensor 152 are disconnected, so that the first relay 221 and the second relay 222 are powered off, and the first normally closed switch group 2211 and the second normally closed switch group 2221 are both closed. At this time, the operator does not output a valve closing control command at the controller 25 end. The control switch 23 does not receive the valve closing control command to disconnect, so that the third relay 223 is powered off, the first normally open switch group 2234 is disconnected, causing the fourth relay 224 to be powered off, and the second normally open switch group 2241 is disconnected. At the same time, the first normally closed switch 2232 and the second normally closed switch 2233 are both closed. Since the first normally closed switch group 2211, the first normally closed switch 2232, the second normally closed switch group 2221 and the second normally closed switch 2233 are all closed, the first relay 221 provides the first power supply 211 with power. The electric energy supplied by the second power source 212 is output to the first electromagnetic telescopic component 131, and the second relay 222 outputs the electric energy supplied by the second power source 212 to the second electromagnetic telescopic component 132, so that the movable electric cores of the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 are ejected to jointly push the valve 11 to open the valve 11; when the valve 11 is opened, the first switch sensor 151 and the second switch sensor 152 do not detect the valve 11 at this time, so the first switch sensor 151 and the second switch sensor 152 are turned on, so that the first relay 221 and the second relay 222 are powered on, and the first normally closed switch group 2211 and the second normally closed switch group 2221 are both disconnected, so that the first relay 221 stops outputting the electric energy supplied by the first power source 211 to the first electromagnetic telescopic component 131, and the second relay 222 stops outputting the electric energy supplied by the second power source 212 to the second electromagnetic telescopic component 132, and the movable electric cores of the first electromagnetic telescopic component 131 and the second electromagnetic telescopic component 132 are returned to their original positions under the action of the spring.

[0109] At the same time, the controller 25 detects that the node state of the third normally open switch group 2212 is in a closed state, and the node state of the fourth normally closed switch group 2222 is in an open state. The controller 25 can determine the state of the valve 11 detected by the first switch sensor 151 and the second switch sensor 152 according to the set logic to determine that the state of the valve 11 is in an open state.

[0110] When the first power supply 211 is abnormally supplied, and the valve 11 is in a closed state, the first switch sensor 151 and the second switch sensor 152 both detect the valve 11, and the first switch sensor 151 and the second switch sensor 152 are disconnected, so that the first relay 221 and the second relay 222 are powered off, and the first normally closed switch group 2211 and the second normally closed switch group 2221 are both closed. At this time, regardless of whether the operator outputs a valve closing control command at the controller 25 end, and whether the control switch 23 receives the valve closing control command, the third relay 223 will be powered off due to the abnormal power supply of the first power supply 211, the first normally open switch group 2234 is disconnected, causing the fourth relay 224 to be powered off, and the second normally open switch group 2241 is disconnected, so the electromagnetic adsorption component 14 cannot generate magnetic force to fix the valve 11. At the same time, the first normally closed switch 2232 and the second normally closed switch 2233 of the third normally closed switch group 2231 are both closed. Since the first normally closed switch group 2211, the first normally closed switch 2232, and the second normally closed switch 2233 of the third normally closed switch group 2231 are both closed, The second normally closed switch group 2221 and the second normally closed switch 2233 are both closed, and the first power supply 211 is abnormal, the first relay 221 stops outputting the electric energy provided by the first power supply 211 to the first electromagnetic telescopic component 131, but the second relay 222 can output the electric energy provided by the second power supply 212 to the second electromagnetic telescopic component 132, so that the movable core of the second electromagnetic telescopic component 132 pops out to push the valve 11 to open the valve 11; when the valve 11 is opened, the first switch sensor 151 and the second switch sensor 152 do not detect the valve 11 at this time, so the first switch sensor 151 and the second switch sensor 152 are turned on, but due to the abnormal power supply of the first power supply 211, only the second relay 222 is powered on, and the second normally closed switch group 2221 is disconnected, so that the second relay 222 stops outputting the electric energy provided by the second power supply 212 to the second electromagnetic telescopic component 132, and the movable core of the second electromagnetic telescopic component 132 returns to its original position under the action of the spring.

[0111] At the same time, the controller 25 detects that the node status of the fourth normally closed switch group 2222 is in the disconnected state. The controller 25 can determine the state of the valve 11 detected by the second switch sensor 152 according to the set logic to determine that the valve 11 is in the open state, and the controller 25 can also determine that the power supply of the first power supply 211 is abnormal.

[0112] When the power supply of the power source 21 is completely interrupted and the valve 11 is in a closed state, the valve 11 is fixed to the valve body 12 by the friction force of the sealing ring. When the combustible gas deflagrates or explodes, the valve 11 can be opened under the action of pressure.

[0113] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
