Description

Technical Field

[0001] The utility model relates to an exhaust valve, in particular to an exhaust valve with a temperature-resistant magnet. Background Art

[0002] In the energy storage industry of new energy, during the operation of batteries in energy storage products, there is a risk of thermal runaway of the batteries, abnormal temperature rise, and further evolution into battery combustion and explosion.

[0003] Most of the existing exhaust valve products on the market control the opening and closing of the exhaust valve cover through a pressure sensor and an electronic control system. This control method has the following disadvantages: 1. It requires a separate power supply for power supply; 2. The structure is relatively complex and the cost is relatively high.

[0004] In view of the above deficiencies in the existing technology of exhaust valves on the market, there is an urgent need for a new type of exhaust valve that can solve the above problems to meet the market demand. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an exhaust valve with a temperature-resistant magnet. The key point of this exhaust valve is to introduce a magnet with high reliability on the exhaust valve. This new type of exhaust valve product adopts a structure that uses a magnet to tightly hold the valve cover: when the air pressure in the chassis rises to a certain level, at this time, the outward pressure of the valve cover is greater than the suction force of the magnet on it, and the valve cover automatically pops open. After the gas in the chassis is discharged, only need to manually close the valve cover again.

[0006] The technical solution of the utility model is: an exhaust valve with a temperature-resistant magnet, including a valve main body assembly, a rotating shaft assembly, a signal assembly, and a magnet assembly;

[0007] The valve main body assembly includes a valve seat and a valve cover;

[0008] The main body of the valve seat is annular. One side of the valve seat protrudes radially and is provided with a rotating shaft assembly installation groove, and the rotating shaft assembly is rotatably fixed in the rotating shaft assembly installation groove; on the other side of the valve seat opposite to the rotating shaft assembly installation groove, it protrudes radially and is provided with a signal assembly installation hole position and a magnet assembly installation groove;

[0009] The head end of the signal assembly is provided with a reset switch. After the signal assembly passes through the signal assembly installation hole position, it is locked and fixed by a hexagon nut;

[0010] The magnet assembly includes an iron plate, a magnet, a limit screw and a spring. The magnet is placed in the installation groove of the magnet assembly, and there is a threaded hole at the bottom of the magnet. A limit screw through-hole is opened on the valve seat at the bottom of the magnet assembly installation groove. After the spring is sleeved on the surface of the limit screw, the tip of the limit screw passes through the limit screw through-hole from bottom to top and is fixedly connected to the threaded hole at the bottom of the magnet; the spring is limited between the bottom surface of the valve seat and the nut of the limit screw;

[0011] One end of the valve cover is rotatably fixed to the rotating shaft assembly, and the iron plate is arranged at the corresponding position of the bottom surface of the valve cover and the magnet; when the valve cover is closed, the iron plate is adsorbed and fixed to the magnet, and the valve cover presses and disconnects the reset switch; when the air pressure rises to a value where the outward pressure on the valve cover is greater than the suction force of the magnet on it, the valve cover bounces open due to the pressure. During this process, when the reset switch loses the pressing force of the valve cover, it changes from the normally open state to the conducting state.

[0012] Furthermore, the valve body assembly further includes an O-ring and a special-shaped rubber ring; the O-ring is embedded in the bottom surface of the valve seat to seal the connection surface between the bottom surface of the valve seat and the external device; the special-shaped rubber ring is embedded in the front surface of the valve seat to seal the front surface of the valve seat and the bottom surface of the valve cover.

[0013] Furthermore, the rotating shaft assembly includes a rotating shaft seat, a rotating shaft and a rotating shaft bracket;

[0014] After the axial mounting holes of the rotating shaft bracket are aligned with the axial mounting holes of the rotating shaft seat, the rotating shaft is inserted into the corresponding axial mounting holes. After the assembly is completed, the rotating shaft assembly is inserted into the rotating shaft assembly installation groove.

[0015] Furthermore, a plurality of mounting holes for connecting with external devices are circumferentially opened on the valve seat.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. Due to the adoption of the magnet structure in this new structure: as long as the valve cover is subjected to a certain air pressure, it can automatically bounce open without a power source and can also work in a state without a control system, which is safe and reliable.

[0018] 2. Due to the simple structure of the magnet part, the product is convenient to assemble, economical and practical, easy to operate, and can save costs. Description of the Drawings

Detailed implementation mode

[0029] The following further describes the present utility model in conjunction with the attached drawings.

[0030] As Figure 1-8 shown, an exhaust valve with a temperature-resistant magnet includes a valve body assembly 101, a rotating shaft assembly 102, a signal assembly 103, and a magnet assembly 104.

[0031] The valve body assembly 101 includes a valve seat 2 and a valve cover 1. The valve seat 2 is circumferentially provided with a plurality of mounting holes for connecting with external devices.

[0032] The main body of the valve seat 2 is annular. One side of the valve seat 2 protrudes radially and is provided with a rotating shaft assembly mounting groove, and the rotating shaft assembly 102 is rotatably fixed in the rotating shaft assembly mounting groove. The other side of the valve seat 2 opposite to the rotating shaft assembly mounting groove protrudes radially and is provided with a signal assembly mounting hole position and a magnet assembly mounting groove.

[0033] The head end of the signal assembly 103 is provided with a reset switch 9, and the signal assembly 103 passes through the signal assembly mounting hole position and is locked and fixed by a hexagon nut 10.

[0034] The magnet assembly 104 includes an iron plate 5, a magnet 6, a limit screw 7, and a spring 8. The magnet 6 is placed in the magnet assembly installation groove, and there is a threaded hole at the bottom of the magnet 6. A limit screw through-hole is provided on the valve seat 2 at the bottom of the magnet assembly installation groove. After the spring 8 is sleeved on the surface of the limit screw 7, the tip of the limit screw 7 passes through the limit screw through-hole from bottom to top and is fixedly connected to the threaded hole at the bottom of the magnet 6. The spring 8 is limited between the bottom surface of the valve seat 2 and the nut of the limit screw 7.

[0035] One end of the valve cover 1 is rotatably fixed to the rotating shaft assembly 102, and the iron plate 5 is arranged at the corresponding position of the bottom surface of the valve cover 1 and the magnet 6. When the valve cover is closed, the iron plate and the magnet are adsorbed and fixed, and the valve cover presses and disconnects the reset switch 9. When the air pressure rises to such an extent that the outward pressure on the valve cover is greater than the suction force of the magnet on it, the valve cover pops open due to the pressure. During this process, when the reset switch loses the pressing force of the valve cover, it changes from the normally open state to the conducting state.

[0036] The installation process of the exhaust valve with a temperature-resistant magnet is as follows:

[0037] 1. Valve body assembly part: Install the O-ring 3 and the special-shaped rubber ring 4 into the corresponding grooves of the valve seat 2 respectively.

[0038] 2. Rotating shaft assembly part: After aligning the rotating shaft bracket 12 with the rotating shaft seat 14, install the rotating shaft 13 into its corresponding hole. After its assembly is completed, install this assembly into the corresponding slot of the valve seat 2 and fix it with a screw 15. Then fix the valve cover 1 to the rotating shaft bracket 12 with a screw 11.

[0039] 3. Signal assembly part: Install the reset switch 9 into the corresponding through-hole position of the valve seat 2, and screw the hexagon nut 10 into the threaded connection part of the reset switch 9 to fix it.

[0040] 4. Magnet assembly part: Fix the steel plate 5 to the valve cover 1 with a screw 16, and fix the magnet 6 to the valve seat 2 with a limit screw 7 and a spring 8.

[0041] 5. After the above-mentioned assembly is completed, close the valve cover, and suck the valve cover together by the suction force of the magnet, and the assembly is completed.

[0042] The working process of this exhaust valve: In the normal state, the valve cover 1 is in a normally closed state under the suction force of the magnet 6. When an abnormal situation occurs in the chassis and gas is generated, when the air pressure rises to a certain value, the outward pressure on the valve cover 1 is greater than the suction force of the magnet 6 on it, and the valve cover 1 pops open due to the pressure, and the gas in the chassis can be discharged through the exhaust valve. When the air pressure returns to the normal value, the valve cover can be manually closed. At the same time, during this process, when the reset switch 9 loses the pressing force of the valve cover, it changes from the normally open state to the conducting state. When the valve cover is closed, the reset switch changes from conducting to disconnected again. In this way, the exhaust valve achieves the function of exhausting gas, and at the same time, the chassis monitoring system can also monitor the working state of the exhaust valve.

[0043] The installation method of this exhaust valve: First, align the exhaust valve with the installation holes on the chassis, and use 4 studs to fix the exhaust valve to the chassis. Then connect the interface on the reset switch to the monitoring system in the chassis, and the installation is completed.

[0044] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
