Description

Technical Field

[0001] The utility model relates to an exhaust valve, in particular to a tension spring type exhaust valve used on an energy storage cabinet. Background Art

[0002] With the development of new energy technologies, the demand for energy storage cabinets is growing. New energy storage cabinets consist of battery packs, battery management systems, inverters, power distribution units, control systems, auxiliary systems, and safety devices (exhaust valves / explosion-proof valves). When the control system detects hazards such as high temperature, high pressure, or flammable gases within the cabinet, it controls the exhaust valve to open and exhaust the gas to ensure cabinet safety.

[0003] Most existing exhaust valves on the market feature a guide rod that fits within a hole. The guide rod is forced to move within the hole to open the valve. However, in practice, these exhaust valves often suffer from slow opening, guide rod jamming, noise, and easily damaged parts, leading to significant safety hazards and potential hazards. Utility Model Content

[0004] In response to the problems existing in the prior art, the utility model provides a tension spring type exhaust valve for an energy storage cabinet, which can alleviate the above problems.

[0005] The technical solution of the utility model is: a tension spring type exhaust valve for an energy storage cabinet, comprising a valve cover, a push rod, a lock buckle, a valve body, a shaft sleeve, a lock, a tension spring and a connecting plate;

[0006] The lock catch is fixedly mounted on the middle portion of the side of the valve cover facing the valve body; the lock is fixedly mounted on the center portion of the valve cover; when the lock catch is locked with the lock, the valve cover and the valve body are sealed;

[0007] The valve body is provided with two mounting holes in a centrally symmetrical manner;

[0008] There are two shaft sleeves, which are fixed in the two mounting holes in a one-to-one correspondence;

[0009] There are two push rods, the middle of which passes through the shaft sleeve, and the two ends of the push rods are fixedly connected to the valve cover and the connecting plate respectively;

[0010] There are two tension springs, and both ends of each tension spring are fixedly connected to the valve cover and the connecting plate respectively.

[0011] Furthermore, it also includes two rubber sleeves, which are respectively sleeved on two push rods located between the valve cover and the connecting plate.

[0012] Furthermore, the push rod is connected to one end of the valve cover and fixed via a flange.

[0013] Furthermore, an inner rubber ring is provided on the side of the valve cover facing the valve body.

[0014] Furthermore, an outer rubber ring is provided on the side of the valve body facing the valve cover.

[0015] Furthermore, hooks are provided at the connection between the valve cover and the tension spring and at the connection between the connecting plate and the tension spring.

[0016] The beneficial effects of the present utility model are: providing a tension spring type exhaust valve for energy storage cabinets, the exhaust valve opening and closing structure selects a push rod, a shaft sleeve and a lock for cooperation. The push rod and the shaft sleeve cooperate in movement, which can play a guiding role and lubrication effect, and prevent the push rod from being blocked and stuck during movement. The double push rod mechanism can make the valve cover evenly stressed, determine the movement trajectory of the valve cover, and prevent the valve cover from being stuck with the valve body due to offset during the opening process. The spring connects the connecting plate and the valve body. After the lock is opened, the larger elastic force of the spring can quickly open the valve cover through the push rod. At the same time, the rubber protective sleeve on the upper end of the push rod can make the hard collision between the connecting plate and the valve body of the valve cover when the valve cover is opened elastically buffered, which not only greatly reduces the collision noise between the frame and the valve body, but also protects the valve body parts from damage.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-3As shown, a tension spring exhaust valve for an energy storage cabinet includes a valve cover 1, an inner rubber ring 2, a flange 3, a push rod 4, a lock 5, an outer rubber ring 6, a valve body 7, a push rod fixing block 8, a shaft sleeve 9, a lock 10, a tension spring 11, a hook 12, a rubber sheath 13, and a connecting plate 14. The lock 5 is fixedly mounted in the middle portion of the side of the valve cover 1 facing the valve body 7. The lock 10 is fixedly mounted in the center portion of the valve cover 1. When the lock 5 and the lock 10 are locked, the valve cover 1 and the valve body 7 are sealed. Two mounting holes are centrally symmetrically defined on the valve body 7. There are two shaft sleeves 9, which are fixed in the two mounting holes in a one-to-one correspondence. There are two push rods 4, the middle portion of which passes through the shaft sleeve 9. The two ends of the push rods 4 are respectively fixedly connected to the valve cover 1 and the connecting plate 14. Two rubber sheaths 13 are respectively mounted on the two push rods 4 located between the valve cover 1 and the connecting plate 14. The push rod 4 is connected to the valve cover 1 at one end and fixed via a flange 3. There are two tension springs 11, each of which is fixedly connected to the valve cover 1 and the connecting plate 14 at both ends. Hooks 12 are provided at the connection points between the valve cover 1 and the tension springs 11, as well as at the connection points between the connecting plate 14 and the tension springs 11. An inner rubber ring 2 is provided on the side of the valve cover 1 facing the valve body 7. An outer rubber ring 6 is provided on the side of the valve body 7 facing the valve cover 1.

[0023] The bonnet and connecting plate are connected by a push rod, which is positioned and guided by a sleeve fixed to the valve body. The sleeve and push rod are precisely matched. A spring connects the valve body and connecting plate, pulling the connecting plate and push rod to move, opening the bonnet. A locking latch is fixed to the bonnet and, when locked with the lock on the valve body, seals the bonnet and valve body.

[0024] The exhaust valve opening and closing structure is coordinated with a push rod, a shaft sleeve, and a lock. The push rod and the shaft sleeve move in coordination, which can play a guiding role and lubricate the effect, preventing the push rod from being blocked or stuck during movement. The double push rod mechanism can evenly apply force to the valve cover, determine the movement trajectory of the valve cover, and prevent the valve cover from being stuck on the corners and the valve body due to offset during the opening process. The spring connects the connecting plate and the valve body. After the lock is opened, the large elastic force of the spring can quickly open the valve cover through the push rod. At the same time, the rubber protective sleeve on the upper end of the push rod can make the hard collision between the connecting plate and the valve body of the valve cover when opening, which not only greatly reduces the collision noise between the frame and the valve body, but also protects the valve body parts from damage.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
