Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to a modular combined drive valve used in a fire extinguishing system. Background Art
[0002] Current battery packs for electric buses and automobiles, as well as for energy storage power stations, are stacked to form battery clusters. These clusters are relatively enclosed and confined. During charging and discharging, the batteries emit flammable gases that accumulate within the battery packs. Once the batteries are overcharged, short-circuited, or leak, thermal runaway can occur, leading to spontaneous combustion. In particular, battery packs are prone to fire and explosion when damaged by external forces, posing a significant threat to life and property. Currently, automatic fire extinguishing systems for battery packs typically consist of a control system, fire detectors, and fire extinguishing devices. When two or more detectors generate an alarm signal, it is fed back to the control host, which then outputs a start signal to activate the fire extinguishing device to fully flood and suppress the fire. Existing technical solutions for automatic fire extinguishing systems for battery packs primarily focus on extinguishing fires across the entire battery cluster. They are unable to suppress or extinguish fires in individual battery packs, nor can they be expanded as battery packs are stacked. This requires the installation of a new fire extinguishing system, increasing costs. Utility Model Content

DETAILED DESCRIPTION
[0029] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0030] The specific embodiment of the utility model provides a modular combined drive valve for a fire extinguishing system. Figure 1 - Attachment Figure 11 As shown, it includes a valve body 1, a sealing component 2, an electric initiator 3, a first connecting hole 4, a second connecting hole 5 and a third connecting hole 6.
[0031] The valve body 1 is the basis for the arrangement of various components, and has a cavity inside;
[0032] The sealing component 2 is provided on the valve body 1. The interior of the valve body 1 is divided into a first cavity 7 and a second cavity 8 by the sealing component 2. The first cavity 7 and the second cavity 8 are separated into two different cavities by the sealing component 2, and the two cavities are not connected to each other.
[0033] The electric initiator 3 is provided on the valve body 1 and is provided with a puncture portion 303 for destroying the sealing component 2 to allow the first cavity 7 and the second cavity 8 to communicate with each other;
[0034] The first connecting hole 4 and the second connecting hole 5 are both connected to the first cavity 7. The first connecting hole 4 and the second connecting hole 5 are provided with a fire extinguishing agent inlet connection portion 9 or a pipe connector 10 or a plugging head;
[0035] When a fire extinguishing agent inlet connection portion 9 is provided on one of the first connection hole 4 and the second connection hole 5, the fire extinguishing agent inlet connection portion 9 can be connected to the pipeline of the fire extinguishing system, and the fire extinguishing agent can enter the first cavity 7 through the fire extinguishing agent inlet connection portion 9;
[0036] When a pipe connector 10 is provided on one or both of the first connecting hole 4 and the second connecting hole 5, the pipe connector 10 can be used to connect to the adjacent valve body 1, thereby connecting multiple valve bodies 1 in series and expanding the modular combined drive valve for the fire extinguishing system. When additional battery packs are added, the modular combined drive valve for the fire extinguishing system can be expanded to meet the needs.
[0037] When a plugging head is provided on one of the first connecting hole 4 and the second connecting hole 5, the connecting hole can be sealed. If a battery pack is added later, the plugging head can be removed for expansion.
[0038] The third connecting hole 6 is connected to the second cavity 8, and a fire extinguishing agent outlet connection portion 11 is provided on the third connecting hole 6. The fire extinguishing agent outlet connection portion 11 is used to connect to the corresponding battery pack. In this way, it can be ensured that each battery pack corresponds to a valve body 1, and the triggering action of the electric initiator 3 on the corresponding valve body 1 can achieve the effect of extinguishing a fire for a certain battery pack.
[0039] In the specific embodiments of this application, Figure 3-7As shown, a fourth connecting hole 12 is provided on the valve body 1, and a tightening step 13 is provided in the fourth connecting hole 12. The sealing component 2 includes a first sealing head 201, a sealing diaphragm 202 and a sealing gasket 203. The first sealing head 201 has a hole groove 2011, and a through hole 2012 is provided on the peripheral side wall of the hole groove 2011. The first sealing head 201 is provided in the fourth connecting hole 12 and the sealing diaphragm 202 is tightened against the tightening step 13 through the sealing gasket 203. At this time, the first sealing head 201 is sealed and connected to the fourth connecting hole 12, and the cavity of the valve body 1 is divided into a first cavity 7 and a second cavity 8 by the sealing diaphragm 202. At this time, the hole groove 2011 contains the first cavity 7, and the first connecting hole 4 and the second connecting hole 5 are both connected to the hole groove 2011 through the through hole 2012. The connected parts on the two connecting holes can be connected via the hole groove 2011, and the fire extinguishing agent can flow to other valve bodies 1 through the hole groove 2011.
[0040] The first sealing head 201 and the fourth connecting hole 12 may be connected by threaded connection.
[0041] The number of sealing gaskets 203 can be two, and they are respectively arranged between the first sealing head 201 and the sealing diaphragm 202 and between the sealing diaphragm 202 and the tightening step 13. The sealing gasket 203 is an annular sealing gasket, and the circumferential side of the annular sealing gasket is tightly fitted with the sealing diaphragm 202 to ensure that the puncture part 303 can puncture the sealing diaphragm 202, thereby connecting the first cavity 7 and the second cavity 8.
[0042] In some embodiments, Figure 8 and attached Figure 9 The electric initiator 3 includes a second sealing head 301, a wire 302, a puncture portion 303 and an elastic member 304. The fifth connection hole 14 is provided at the end of the valve body 1 away from the fourth connection hole 12, and the fifth connection hole 14 is communicated with the fourth connection hole 12. The second sealing head 301 is provided in the fifth connection hole 14, and the wire 302 is provided at the end of the second sealing head 301 facing the fifth connection hole 14. The puncture portion 303 is provided in the fifth connection hole 14 through the elastic member 304. The wire 302 is close to the tail end of the puncture portion 303, and the puncture end of the puncture portion 303 faces the sealing diaphragm 202. The elastic member 304 has a tendency to push the puncture portion 303 to move in a direction away from the sealing diaphragm 202.
[0043] The second sealing head 301 and the fifth connecting hole 14 can be connected by a threaded connection. The trigger portion of the wire 302 is disposed inside the fifth connecting hole 14, while the wire of the wire 302 passes through the second sealing head 301 and is connected to an external control device. The elastic member 304 can be a spring. To this end, a circumferential convex ring is provided on the puncture portion 303, and a corresponding convex ring is provided on the inner wall of the fifth connecting hole 14 and near the fourth connecting hole 12. A spring is provided between the two convex rings. The spring can prevent the puncture portion 303 from puncturing the sealing diaphragm 202 under normal conditions. The puncture end of the puncture portion 303 faces the sealing diaphragm 202. To this end, the fifth connecting hole 14 and the fourth connecting hole 12 can be configured as a coaxial hole structure.
[0044] In some embodiments, Figure 10 and attached Figure 11 As shown, the puncture part 303 includes a tight end cap 3031 and a puncture rod 3032. The tight end cap 3031 has a pit 3033 facing the wire 302. The wire 302 is located in the pit 3033. The wire 302 is started after receiving the start control signal sent by the control device. The wire 302 pushes the tight end cap 3031 and drives the puncture rod 3032 to move. One end of the puncture rod 3032 is connected to one end of the end cap 3031 away from the pit 3033, and the other end of the puncture rod 3032 has a pointed head 3034, which is convenient for puncturing the sealing membrane 202; a blind hole 3035 is provided on the puncture rod 3032 near the pointed head 3034, and a strip hole 3036 is provided on the side wall of the blind hole 3035. When the puncture part 303 punctures into the first cavity 7, the first cavity 7 and the second cavity 8 are connected through the strip hole 3036. In this way, the first cavity 7 and the second cavity 8 can be connected as soon as possible after the puncture part 303 penetrates the sealing membrane 202, so that the fire extinguishing agent can enter the battery pack as quickly as possible to extinguish the fire.
[0045] In some embodiments, the first connecting hole 4 and the second connecting hole 5 are coaxially arranged, and the first connecting hole 4 and the second connecting hole 5 are both opposite to the through hole 2012, so that the first connecting hole 4 and the second connecting hole 5 are respectively located on the opposite side walls of the valve body 1. This arrangement facilitates side-by-side connection between the valve bodies 1.
[0046] In a specific embodiment of the present application, there are two valve bodies 1, which are connected by a pipe connector 10. A fire extinguishing agent inlet connection part 9 is provided on both valve bodies 1. In this way, both ends are connected to the pipeline of the fire extinguishing system through the fire extinguishing agent inlet connection part 9, thereby ensuring that the fire extinguishing agent can pass through the inside of the valve body 1 quickly.
[0047] In some embodiments, the fire extinguishing agent inlet connection portion 9 and the fire extinguishing agent outlet connection portion 11 are both quick-connect connectors. The quick-connect connectors enable the fire extinguishing agent inlet connection portion 9 and the fire extinguishing agent outlet connection portion 11 to be connected relatively quickly.
[0048] It should be noted that the pipe connector 10 in the present application can be a double-threaded straight-through or tee, etc. The connection can be made according to the actual connection conditions required.
