Description

Technical Field

[0002] The mechanical seal box of the equipment usually contains batteries or other power sources. Due to the characteristics of its sealing structure, if an accident occurs, it may easily lead to casualties and property losses, posing a greater safety risk to users.

[0003] Among them, the needle-puncture explosion-proof valve exchanges air with the outside world through a layer of waterproof and breathable membrane. When the internal pressure of the battery box cavity reaches a certain pressure, the waterproof and breathable membrane expands, thereby approaching the stationary needle tip inside, so that the needle tip can pierce the waterproof and breathable membrane, thereby achieving pressure relief.

[0004] However, in this case, a static ejector is required to puncture the waterproof breathable membrane that expands under high pressure, and the blasting effect can only be achieved under high pressure. In addition, the pressure relief area of ​​the waterproof breathable membrane punctured by the static ejector is small, and rapid blasting cannot be achieved. Utility Model Content

[0029] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0031] In the following embodiments, Figure 1 and Figure 2 The coordinate system is taken as the reference, the X-axis direction is left and right, the Y-axis direction is front and back, and the Z-axis direction is up and down.

[0032] Embodiment 1:

[0033] like Figures 1 to 3 As shown, in this embodiment, a bidirectional motion ejector-type explosion-proof valve 10 comprises: a valve body 100, comprising a mounting portion and a trigger portion arranged on one side of the mounting portion, an air passage 110 is arranged between the trigger portion and the mounting portion; an opening penetrating the mounting portion is arranged on the mounting portion, the opening is communicated with the air passage 110, and mounting positions 120 are respectively arranged at the openings on both sides of the opening; at least two membrane papers 200 are respectively arranged on the mounting positions 120 on both sides of the mounting portion; and at least two ejector pins 300 are respectively arranged on at least two membrane papers 200, and the piercing end of the ejector pin 300 faces another opposite membrane paper 200, and there is a safe distance between the piercing end and the membrane paper 200 opposite to it, so as to avoid affecting the performance of the membrane material when high-frequency movement is generated during slight air pressure difference, transportation, etc.

[0034] Specifically, the number of the membrane paper 200 and the ejector pin 300 is set to 2. It is understandable that the number of the membrane paper 200 and the ejector pin 300 can be set to 4. The valve body 100 is set to be a valve body 100 that is wide at the top and narrow at the bottom, that is, the cross-sectional area of ​​the triggering part is larger, and the cross-sectional area of ​​the mounting part is smaller, and it is set in a T-shape. In another embodiment, the triggering part can also form an oblique angle with the mounting part, or the upper and lower widths are the same, etc., and its specific setting can be determined according to actual conditions, and this application does not limit this. The end face of the triggering part is set to be concave toward the middle, and the end face of the triggering part is provided with an airway 110 along the direction toward the mounting part. The mounting part is provided with a through opening along the X-axis direction, and the opening is connected to the airway 110, and the outer surfaces on the left and right sides of the mounting part are respectively provided with mounting positions 120 facing inward. In another embodiment, the inner surfaces on the left and right sides of the mounting part can be provided with mounting positions 120 facing outward, that is, the left and right side walls of the airway 110 are provided with mounting positions 120 facing outward, and its specific setting can be determined according to actual conditions, and this application does not limit this. The shape of the mounting position 120 is compatible with the shape of the membrane paper 200. The shape of the membrane paper 200 is circular. In another embodiment, the shape of the membrane paper 200 may be square. The specific setting may be determined according to the actual situation, and the present application does not limit this. The membrane paper 200 is configured as a waterproof and breathable membrane. The membrane paper 200 has a certain ductility so as to expand and contract. When the material of the valve body 100 is plastic, the membrane paper 200 is connected to the valve body 100 by welding. In another embodiment, when the material of the valve body 100 is metal, the membrane paper 200 may be bonded to the valve body 100. The specific setting may be determined according to the actual situation, and the present application does not limit this. The ejector pin 300 has a connecting end and a puncturing end. The ejector pin 300 is connected to the membrane paper 200 through the connecting end. The connecting end of the ejector pin 300 is welded to the surface of the membrane paper 200. The shape of the ejector pin 300 is based on actual production requirements. For example, the cross-sectional area of ​​the connecting end of the ejector pin 300 is larger than the cross-sectional area of ​​the puncturing end. Reference Figure 2 When the left end ejector pin 300 is connected to the left end film paper 200, the piercing end of the left end ejector pin 300 is arranged toward the right end film paper 200, so that when the left end film paper 200 is compressed and expands to the right, the left end ejector pin 300 pierces the right end film paper 200, and the same applies to the right end ejector pin 300.

[0035] In this way, by installing the two-way motion ejector pin explosion-proof valve 10 in an external sealed box, the cavity in the external sealed box can be isolated from the airway 110 by the membrane paper 200, and the airway 110 is connected to the external gas. When the gas pressure inside the external sealed box is greater than or equal to the pressure value set by the two-way motion ejector pin explosion-proof valve 10, the explosion-proof valve explodes and releases pressure. At this time, under the action of the internal pressure of the external sealed box, the membrane papers 200 on both sides expand due to the increase in the internal pressure of the external sealed box, so that the membrane papers 200 connected to the two sides of the installation part are close to each other. At this time, the ejector pins 300 provided on the membrane papers 200 on both sides quickly pierce the membrane paper 200 on the other side opposite to it, so that the air pressure inside the sealed box can be quickly released, thereby achieving pressure balance inside and outside the sealed box. The bidirectional motion structure of the ejector pin 300 and the membrane paper 200 shortens the travel required when the membrane paper 200 ruptures, and the explosion is achieved quickly. The setting of the double membrane paper 200 increases the pressure relief area, and the pressure inside the sealed box is quickly relieved. At the same time, it ensures that the product will not fail to seal and pressure relief due to the internal and external pressure difference exceeding its tolerance capacity under normal working conditions when the external environment changes.

[0036] In order to increase the practicality of the valve body 100, as Figure 3 As shown, in some embodiments, a sealing ring 140 for sealingly connecting with an external sealed box is installed on the outer surface of the trigger portion.

[0037] Specifically, the air tightness of the external sealing box is ensured, and the practicality of the valve body 100 is increased.

[0038] In order to prevent the entry of dust, particles, etc. and affect the performance of the film paper 200, such as Figure 1 and Figure 2 As shown, in some embodiments, a cover 130 is installed on the trigger portion.

[0039] Specifically, a groove is provided on the end surface of the trigger part, and a convex ring matching the groove is provided on the cover body 130, and the convex ring is engaged with the side wall of the groove, so that the valve body 100 is connected with the cover body 130, thereby preventing external dust from entering the airway 110. When the two film papers 200 rupture and release pressure, the gas in the airway 110 can flush out the cover body 130. It is understandable that the cover body 130 and the valve body 100 can be loosely connected by other means, such as snap connection, interference fit or easy-to-tear adhesive bonding.

[0040] In another embodiment, the cover body 130 is tightly connected to the trigger part, and a gas hole is opened on the top surface of the cover body 130 to discharge the gas in the airway 110.

[0041] In yet another embodiment, a gap is provided between the cover 130 and the trigger portion for exhausting the gas in the air passage 110 .

[0042] Embodiment 2:

[0043] This embodiment is a further implementation of the embodiment 1. In this embodiment, the angle formed by the ends of the two oppositely disposed film papers 200 away from the triggering portion is less than or equal to 180°.

[0044] It can be understood that the mounting position 120 is arranged corresponding to the film paper 200, and the arrangement of the film paper 200 can be arranged according to actual production requirements:

[0045] like Figure 2 and Figure 3 As shown, in one embodiment, the angle formed by the ends of the two oppositely arranged membrane papers 200 away from the trigger portion is equal to 180°. In this way, the two membrane papers 200 are arranged parallel to each other, and the width of the opening is less than the width of the mounting position 120, so that the membrane paper 200 can be connected to the bottom of the mounting position 120, and the two membrane papers 200 are arranged at intervals from each other to reduce the mutual influence between the two membrane papers 200. Furthermore, the airway 110 is vertically opened along the Z-axis direction, and the two membrane papers 200 are vertically installed along the Z-axis direction, that is, the three are arranged parallel to each other, so that when the membrane papers 200 on both sides are broken, the internal airflow flows into the airway 110 in the same direction, which is convenient for the pressure relief process.

[0046] The mounting position 120 is set corresponding to the film paper 200, and the relationship between the two film papers 200 is set according to actual production requirements:

[0047] For example, Figure 2 As shown, two oppositely disposed film papers 200 are disposed parallel to each other, and the two oppositely disposed film papers 200 are partially staggered.

[0048] For another example, two oppositely disposed film papers 200 are disposed parallel to each other, and the two oppositely disposed film papers 200 are disposed side by side.

[0049] In another embodiment, the angle formed by the ends of the two relatively arranged membrane papers 200 away from the trigger portion is less than 180°. For example, the angle formed by the ends of the two membrane papers 200 close to the bottom of the airway 110 is an acute angle. In this way, the two mounting grooves form a V-shape, the bottoms of the two mounting grooves pass through the airway 110, the membrane papers 200 are connected to the side walls of the mounting grooves, and the bottom ends of the two membrane papers 200 intersect, so that the two membrane papers 200 form a Y-shape, making the volume of the bottom end of the valve body 100 smaller. For another example, the angle formed by the ends of the two membrane papers 200 close to the bottom of the airway 110 is a right angle. For another example, the angle formed by the ends of the two membrane papers 200 close to the bottom of the airway 110 is an obtuse angle.

[0050] Example 3

[0051] This embodiment is a further implementation of embodiment 1. In this embodiment, the piercing end of the ejector pin 300 is arranged opposite to the center of the film paper 200 arranged opposite to it, so that the ejector pin 300 pierces the center of the film paper 200 arranged opposite to it, and the piercing ends are arranged staggered with each other.

[0052] Specifically, by pointing the piercing end of the left end pin 300 toward the center point of the right end film paper 200, and the piercing end of the right end pin 300 toward the center point of the left end film paper 200, the film papers 200 on both sides are ruptured in the center under pressure, effectively increasing the pressure relief area and achieving a better pressure relief effect.

[0053] When the two membrane papers 200 are parallel to each other and partially staggered, the membrane papers 200 and the ejector pins 300 may be configured as follows: Figure 2 , the left end film paper 200 is biased downward, the right end film paper 200 is biased upward, and the puncture end of the left end ejector 300 and the puncture end of the right end ejector 300 are both aligned with the center of the film paper 200 that is oppositely arranged. For another example, the left end film paper 200 is biased forward, the right end film paper 200 is biased backward, and the puncture end of the left end ejector 300 and the puncture end of the right end ejector 300 are both aligned with the center of the film paper 200 that is oppositely arranged.

[0054] Example 4

[0055] This embodiment is a further implementation of embodiment 1. Figure 1 and Figure 2 As shown, in this embodiment, the bidirectional motion ejector-type explosion-proof valve 10 further includes at least two pressure rings 400 for pressing the membrane paper 200 , and each membrane paper 200 is fixed between a pressure ring 400 and the valve body 100 .

[0056] Specifically, the two membrane papers 200 are fixed on the valve body 100 by using the pressing ring 400 , so that the membrane papers 200 can be firmly positioned, which facilitates the installation of the membrane papers 200 .

[0057] Further, the depth of the mounting position 120 is greater than or equal to the sum of the thickness of the film paper 200 and the thickness of the pressing ring 400. In this way, the pressing ring 400 is prevented from easily detaching from the mounting position 120, thereby increasing practicality.

[0058] In order to further prevent the external environment from affecting the performance of the film paper 200, such as Figures 1 to 3 As shown, in some embodiments, a pressure strip 410 extending to the middle of the film paper 200 is provided on the pressure ring 400 , and the pressure strip 410 abuts against the film paper 200 .

[0059] Specifically, a pressure strip 410 is provided on the pressure ring 400, and the pressure strip 410 is staggered with the piercing end of the ejector pin 300 which is spaced apart from it. Through the supporting effect of the pressure strip 410, the slight vibration of the membrane paper 200 caused by external influences can be effectively mitigated, thereby preventing the membrane paper 200 from generating high-frequency movement during internal and external air pressure, transportation, etc., which affects the performance of the membrane material.

[0060] In another embodiment, the pressure strip 410 is made of elastic material, and the pressure strip 410 is connected to the film paper 200 .

[0061] Specifically, the pressure strip 410 is fixedly connected to the film paper 210. When the film paper 200 expands, the pressure strip 410 moves with the film paper 200. The pressure strip 410 has a certain hardness, so it can support the ejector pin 300, thereby facilitating the ejector pin 300 to pierce the film paper 200 opposite to it, so that the ejector pin 300 has a greater hardness when piercing the relative film paper 200.

[0062] In order to increase the hardness of the ejector pin 300, as Figure 2 As shown, in some embodiments, one end of the pressure strip 410 is connected to the pressure ring 400 , and the other end of the pressure strip 410 is disposed opposite to the adjacent ejector pin 300 .

[0063] Specifically, the other end of the pressure strip 410 is arranged corresponding to the ejector pin 300 across the film paper 200. By the pressure strip 410 being arranged corresponding to the adjacent ejector pin 300, the film paper 200 is further prevented from being slightly vibrated by external influences, and the anti-interference effect is better.

[0064] Embodiment 5:

[0065] This embodiment is a further implementation of Embodiment 4. In this embodiment, two oppositely arranged film papers 200 are arranged in parallel, the piercing end of the ejector pin 300 is arranged opposite to the center of the film paper 200 to which it is connected, and is also arranged opposite to the center of the film paper 200 opposite to it; the pressure ring 400 is provided with a positioning portion, and the two oppositely arranged pressure rings 400 are arranged in opposite directions so that the two positioning portions are in opposite directions.

[0066] Specifically, a positioning portion is provided on one side of the pressure ring 400 connected to the pressure strip 410, as shown in FIG. Figure 2 By installing the ejector pin 300, the film paper 200 and the pressure ring 400 in correspondence, the two film papers 200 are arranged opposite to each other, and the pressure ring 400 is arranged oppositely. At this time, the positioning part on the left pressure ring 400 faces upward, and the positioning part on the right pressure ring 400 faces downward. While ensuring a better pressure relief effect, the installation is more stable, thereby achieving a better assembly effect.

[0067] In order to facilitate the ejector pin 300 to maintain the puncture direction, Figure 2As shown, in some embodiments, a guide surface is disposed on one side of the ejector pin 300, and two oppositely disposed guide surfaces are slidably connected.

[0068] Specifically, the shape of the ejector pin 300 is set to be a side-mounted semi-cone, which is cut along the axial direction, and its cut surface is set as a guide surface. The connecting end of each ejector pin 300 is connected to a positioning portion, and the puncture end faces the film paper 200 arranged opposite thereto, and the connecting end of the ejector pin 300 has a chamfer. During assembly, the film paper 200 on the left and the film paper 200 on the right are arranged side by side, the guiding surface of the ejector pin 300 on the left end faces downward, and the guiding surface of the ejector pin 300 on the right end faces upward, so that the puncture ends of the two ejector pins 300 are both facing the center of the film paper 200 arranged opposite thereto, and when the two are close to each other, the two guiding surfaces are slidably connected, thereby limiting the sliding direction of the ejector pin 300. In this way, while facilitating the installation of the ejector pin 300, it is possible to ensure that the ejector pin 300 is in the required puncture direction, improve the directivity and puncture reliability, and make the impact force on the film paper 200 more uniform, thereby ensuring a better pressure relief effect.
