As shown in fig. 1 to 3, the fire-fighting thermo-sensitive device of the embodiment includes a valve body 1, a water inlet 2 and at least one water outlet 3 are arranged on the valve body 1, a valve core assembly 4 for separating the water inlet 2 and the water outlet 3 is arranged in the valve body 1, and a thermo-sensitive locking mechanism 5 for locking the valve core assembly 4 is arranged on the valve body 1.
This fire control heat-sensitive device has set up the case subassembly between valve body water inlet and delivery port for cut off the rivers, and temperature sensing type locking mechanism is established to the case subassembly, and when the protection zone high temperature, temperature sensing type locking mechanism became invalid, and the water that the water inlet let in flushes the case subassembly, flows out from the delivery port and realizes putting out a fire. Simple structure, the temperature can control out water, does not need manual valve opening, avoids hindering the time of saving a fire.
In this embodiment, the valve core assembly 4 includes a valve core 6, a locking groove 7 is formed in the valve core 6, the thermosensitive locking mechanism 5 includes a top core 11 extending into the locking groove 7, a first elastic member 9 is arranged between the valve core 6 and the valve body 1, and the first elastic member 9 and the water inlet 2 are arranged on two sides of the valve core 6 relatively. Under the normal state, the top core 11 is clamped in the locking groove 7, and the valve core assembly 4 is locked. When the temperature of the protection area is too high, the thermosensitive locking mechanism 5 fails, the top core 11 exits from the locking groove 7, water flow starts to push the valve core assembly 4, the thrust applied to the valve core assembly 4 by water is continuously greater than the elastic force applied by the first elastic piece 9, finally the valve core assembly 4 is pushed away, and the water is sprayed out from the water outlet 3 to extinguish a fire. After the fire extinguishing work is finished, the driving force of the water supply valve core assembly 4 disappears, the valve core assembly 4 resets under the elastic action of the first elastic piece 9, the top core 11 can clamp the locking groove 7 again to separate the water inlet 2 from each water outlet 3, so that the residual water flow does not enter the water outlet 3 any more, and the water dripping is prevented.
In this embodiment, the sealing surface between the valve element 6 and the valve body 1 includes a conical surface and a cylindrical surface, and both are provided with a seal ring 10. Wherein, the sealing ring 10 arranged on the conical sealing surface is a main sealing structure; the sealing ring 10 arranged on the cylindrical sealing surface is used for auxiliary sealing, when the sealing ring 10 arranged on the conical sealing surface is too large or the groove 7 has processing position deviation, the sealing can be further sealed through the interference fit of the sealing ring 10 arranged on the cylindrical sealing surface and the inner wall of the valve body 1, and the sealing structure is a second safety device.
In this embodiment, the heat-sensitive locking mechanism 5 includes a detachable glass bulb seat 13 and a glass bulb 14, the glass bulb 14 is disposed between the glass bulb seat 13 and the top core 11, and a second elastic member 12 is disposed between the top core 11 and the valve body 1. When the protection temperature is too high, the glass bulb 14 is broken, the second elastic piece 12 pushes the ejection core 11 to exit from the locking groove 7, the locking is failed, and the fire extinguishing is started. After fire extinguishing, the glass bulb seat 13 is detached, the top core 11 is stretched into the locking groove 7 again, the glass bulb 14 is replaced, the glass bulb seat 13 is installed, and the normal state is recovered.
In this embodiment, the first elastic member 9 and the second elastic member 12 are both springs. Of course, in other embodiments, electronic control may be used. The spring is preferred, the manufacturing cost is low, and the replacement is convenient.
In this embodiment, the valve core 6 is provided with a valve core shaft 8, one end of the valve body 1 away from the water inlet 2 is provided with a plugging cap 15, and the valve core shaft 8 penetrates through the plugging cap 15. When the locking is failed and the valve core assembly 4 starts to move, the gas in the valve body 1 can pass through the gap between the blocking cap 15 and the valve body 1, and the moving resistance is reduced. The valve core shaft 8 penetrates through the plugging cap, so that the guiding effect can be achieved, and the valve core shaft 8 is conveniently pushed outside the valve body 1 to further achieve the resetting of the valve core assembly 4.
In this embodiment, the valve plug shaft 8 is provided with a limiting table 16 matched with the plugging cap 15, and the limiting table 16 is also provided with a sealing ring 10. The stop 16 can abut against an opening in the plug cap 15 to limit movement of the spool shaft 8, prevent the spool shaft 8 from being damaged by excessive extension, and prevent the spool assembly 4 from being reset. Establish sealing washer 10 on spacing platform 16, when water promotes valve element group spare 4, spacing platform 16 supports when the opening, sealing washer 10 is near stifled cap 15, and the driving force of water is big more this moment, and sealed effect is better.
As shown in fig. 4, the fire fighting system of the embodiment includes a partition valve 17 and a plurality of the above thermosensitive devices, the partition valve 17 is provided with a water inlet channel and a water outlet channel, a water inlet 2 of the thermosensitive device is communicated with the water outlet channel, and each water outlet 3 of the thermosensitive device is connected with a water mist nozzle 18.
The fire fighting system comprises the thermosensitive device, so the fire fighting system also has the advantages, a plurality of thermosensitive devices can be arranged in different protection areas and controlled by one partition valve 17, the arrangement of the partition valve 17 can be reduced, and the cost is reduced; also can accurate protection, need not every temperature sensing device and all put out a fire simultaneously, realize that a subregion valve 17 controls multizone protection.
In this embodiment, the partition valve 17 is a wet partition valve. When a fire disaster happens, a fire alarm signal can be sent out in time and the fire pump is started.
The utility model relates to a fire control heat sensing device's working process as follows: when the conflagration breaing out, the temperature risees, and glass bubble 13 breaks, and the locking is inefficacy, and spring that is in under the compression state originally pushes away top core 11 and withdraws from locking groove 7, and rivers begin to promote valve core subassembly 4, and the driving force of water lasts and is greater than the elasticity of spring this moment, and final case 6 is pushed away, and the opening on stifled cap 15 is supported to case axle 8, realizes spacingly, and water is put out a fire from 3 blowout of each delivery port. After the fire is extinguished, the water flow stops, the valve core assembly 4 resets under the action of the spring and the valve body 1 to push the valve core shaft 8, the top core 11 is clamped in the locking groove 7 again, and the glass bulb 14 is replaced.
The utility model relates to a fire extinguishing system's working process as follows: a plurality of thermosensitive devices are controlled by a wet type subarea alarm valve, when a fire breaks out in a protected area, the fire area thermosensitive device starts the fire extinguishing function, the wet type subarea alarm valve sends out a fire alarm signal and starts a fire pump, but the thermosensitive device is still in an original state in the protected area without the fire.
It should be noted that although the present invention has been described with reference to the preferred embodiments, the present invention is not limited thereto. The technical solution of the present invention can be used by anyone skilled in the art to make many possible variations and modifications, or to modify equivalent embodiments, without departing from the scope of the technical solution of the present invention, using the technical content disclosed above.
