Description

Valve module, valve group and fire extinguishing device
Technical Field
The invention relates to the field of fire extinguishing devices, in particular to a valve module, a valve bank and a fire extinguishing device.
Background
There is an indirect fire detecting tube fire extinguishing apparatus in the prior art, which uses the fire detecting tube as a fire detecting and starting part and uses a releasing tube and a nozzle as a fire extinguishing agent releasing part.
The fire detecting tube is connected to the fire extinguishing agent storage device through the container valve and fixed near the position where the fire source is likely to occur to detect the fire source, when the fire is met, the fire detecting tube is softened and exploded at the position with the highest heating temperature, the container valve of the fire extinguishing agent bottle group is started by utilizing the pressure reduction in the fire detecting tube, the fire extinguishing agent flows to the nozzle through the release pipe, and the nozzle releases the fire extinguishing agent to extinguish the fire.
The indirect fire detecting tube fire extinguishing device in the market is generally used for protecting a space for one set of system. But a plurality of protected spaces which are relatively close and independent are very cost-effective solutions if one set of fire extinguishing apparatus can be used to protect a plurality of spaces simultaneously.
In order to realize that the set of indirect fire detecting tube fire extinguishing device protects a plurality of protected spaces, a fire extinguishing controller, a multi-channel signal feedback device and a plurality of electromagnetic valves are added in the design scheme to serve as a partition control valve and a multi-channel check valve. According to fire-fighting requirements, the fire extinguisher needs to be provided with a standby power supply in addition to a normal power supply.
As shown in fig. 1, the fire extinguishing apparatus mainly comprises an indirect fire detecting tube fire extinguishing apparatus cylinder group 1, a fire extinguishing controller 2, a partition electromagnetic valve 3, a fire extinguishing agent delivery pipeline joint, a spray head 4, a check valve 5, a fire detecting tube and a signal feedback device 6.
When a fire disaster happens to a certain protected area, the fire detecting tube arranged in the protected area is heated and broken, the internal pressure is reduced, the signal feedback device 6 in the area feeds back pressure reduction information to the fire extinguishing controller 2, the fire detecting tube is reduced in pressure, and meanwhile, the fire extinguishing agent bottle group container valve started at low pressure is started, and fire extinguishing agent is sprayed and released. After receiving the signal of the signal feedback device 6, the fire extinguishing controller 2 starts the partition electromagnetic valve 3 of the corresponding area, so that the fire extinguishing agent can flow to the spray head 4 of the area, and the fire extinguishing function of releasing the fire extinguishing agent is realized. When the pressure of the fire detecting pipe in one area is reduced, in order to avoid that the pressure in the fire detecting pipes in other areas connected in parallel is also reduced and the fire extinguishing agent is sprayed by mistake, a check valve 5 is required to be added in each fire detecting pipe.
The product structure of the mode is more complicated, the product reliability is low, and the cost is very high.

By applying the technical scheme of the invention, when a plurality of protection zones need to be protected, a plurality of valve modules with the same number as or more than the number of the protection zones are connected together to form a valve group. When a plurality of valve modules are installed, the installation planes of two adjacent valve modules are required to be opposite, the fire detecting pipe starting main pipes of the two adjacent valve modules are communicated to form a fire detecting pipe starting main pipe, and the fire extinguishing agent spraying main pipes of the two adjacent valve modules are communicated to form a fire extinguishing agent spraying main pipe. And finally, one end of the fire detecting pipe starting main pipe and one end of the fire extinguishing agent spraying main pipe are blocked. When the fire detecting pipe in one protection area is heated and broken, the pressure in the check valve chamber and the control valve chamber communicated with the fire detecting pipe connecting channel corresponding to the fire detecting pipe is reduced, so that the check valve core cannot be pressed by the first elastic piece in the chamber, the fire detecting pipe starts gas in the main pipeline to jack the check valve core, and the gas after jacking the check valve core is discharged from the fire detecting pipe connecting channel, so that the container valve of the fire extinguishing storage bottle is opened.

For the chambers corresponding to other protection areas which are not ignited, the control valve chamber still has preset pressure, so even if the fire extinguishing agent applies upward ejection force to the valve core of the control valve, the valve core of the control valve still keeps at the second blocking position under the resultant force of the pressure of the chambers and the elastic force, and finally the fire extinguishing agent is not sprayed in the protection areas which are not ignited.

As shown in fig. 2 to 11, the valve module of the present embodiment includes: the fire extinguishing agent spraying device comprises a valve body 10, a fire detecting pipe starting main pipe 20, a fire extinguishing agent spraying main pipe 30, a chamber 40, a check valve core 50, a first elastic piece 60, a control valve core 70 and a second elastic piece 80. The valve body 10 includes two mounting planes 111 arranged oppositely along a preset direction n and a mounting side 112 located between the mounting planes 111. The main fire detecting pipe starting pipe 20 is disposed on the valve body 10 along a preset direction n and penetrates through the two mounting planes 111. The main fire extinguishing agent discharging pipe 30 is disposed on the valve body 10 along a predetermined direction n and penetrates the two mounting planes 111. The chamber 40 includes a check valve chamber 41, a control valve chamber 42, a first communication channel 43 communicating the check valve chamber 41 with the control valve chamber 42, a fire detecting pipe connection channel 44 and a spray head connection channel 45 communicating the control valve chamber 42 with the outside atmosphere, a second communication channel 46 communicating the check valve chamber 41 with the fire detecting pipe starting main pipe 20, and a third communication channel 47 communicating the control valve chamber 42 with the fire extinguishing agent discharging main pipe 30, wherein outlets of the fire detecting pipe connection channel 44 and the spray head connection channel 45 are located on the installation side surface 112, and a communication port of the spray head connection channel 45 communicating with the control valve chamber 42 is located between a communication port of the fire detecting pipe connection channel 44 communicating with the control valve chamber 42 and the third communication channel 47. A check valve spool 50 is movably disposed within the check valve chamber 41, a junction of the check valve chamber 41 and the second communication passage 46 forming the first port 48, the check valve spool 50 having a first blocking position blocking the first port 48 and a first open position opening the first port 48. The first elastic member 60 applies an elastic force to the check valve spool 50 toward the first port 48. The control valve spool 70 is movably disposed in the control valve chamber 42, the control valve spool 70 separates the first communicating channel 43 and the fire detecting pipe connecting channel 44 from the nozzle connecting channel 45 and the main fire extinguishing agent discharging pipeline 30, a second valve port 49 is formed at a connecting position of the control valve chamber 42 and the third communicating channel 47, the control valve spool 70 has a second blocking position for blocking the second valve port 49 and a second opening position for opening the second valve port 49, and the main fire extinguishing agent discharging pipeline 30 is communicated with the nozzle connecting channel 45 when the control valve spool 70 is located at the second opening position. The second elastic member 80 applies an elastic force to the control valve spool 70 toward the second port 49.
By applying the technical scheme of the embodiment, when a plurality of protection zones need to be protected, a plurality of valve modules with the number same as or more than that of the protection zones are connected together to form a valve group. When a plurality of valve modules are installed, it is necessary to make the installation planes 111 of two adjacent valve modules opposite, the fire detecting pipe starting main pipes 20 of two adjacent valve modules are communicated to form a fire detecting pipe starting main pipe, and the fire extinguishing agent discharging main pipes 30 of two adjacent valve modules are communicated to form a fire extinguishing agent discharging main pipe. And finally, one end of the fire detecting pipe starting main pipe and one end of the fire extinguishing agent spraying main pipe are blocked. When the fire detecting tube in one of the protection areas is heated and broken, the pressure in the check valve chamber 41 and the control valve chamber 42 communicated with the fire detecting tube connecting channel 44 corresponding to the fire detecting tube is reduced, so that the check valve core 50 cannot be pressed by the first elastic member 60 in the chamber 40 alone, the fire detecting tube starts the gas in the main pipe 20 to jack up the check valve core 50, and the gas is discharged from the fire detecting tube connecting channel 44 after the check valve core 50 is jacked up, so that the container valve of the fire extinguishing storage bottle is opened. Once the container valve is opened, the fire suppressant in the fire suppression storage bottle will enter the main fire suppressant discharge conduit 30. The fire extinguishing agent entering the main fire extinguishing agent discharging pipeline 30 can push the control valve spool 70 in the control valve chamber 42 with the pressure released to the second opening position, so that the fire extinguishing agent can be sprayed out from the nozzle connecting channel 45, and finally the fire extinguishing agent is sprayed to the corresponding protection area through the nozzle connected with the nozzle connecting channel 45, thereby achieving the purpose of extinguishing the fire in the protection area. In addition, according to the present embodiment, the control valve spool 70 is abutted against the second port 49 by the resultant force of the gas pressure in the control valve chamber 42 and the elastic force of the second elastic member 80. The fire suppressant in the main fire suppressant discharge conduit 30 exerts an upward pressure on the control valve spool 70 that is less than the resultant force, so that the fire suppressant can push the control valve spool 70 to move to the second open position only when the pressure in the control valve chamber 42 in the chamber 40 corresponding to the protected area of fire is released. For the chamber 40 corresponding to the other un-ignited protected area, since the control valve chamber 42 still has the preset pressure, even if the fire extinguishing agent exerts an upward pushing force on the control valve spool 70, the control valve spool 70 is still kept at the second blocking position under the combined force of the chamber pressure and the elastic force, and finally, the fire extinguishing agent is not sprayed in the un-ignited protected area. Therefore, the structure can realize the purpose of extinguishing fire for a specific protection area, the fire extinguishment among a plurality of protection areas is not interfered with each other, and the phenomenon that the fire extinguishing agent is sprayed into the protection areas which are not on fire cannot occur.

After the corresponding, the bolt penetrates through the module mounting hole 116, and finally the nut is screwed down. The connecting mode is simple and easy to assemble. Preferably, in the present embodiment, the number of the module mounting holes 116 is four, and four module mounting holes 116 are provided at four corners of the valve module.
As shown in fig. 4, in the present embodiment, the valve body 10 includes a valve body 11, a check valve plugging cover 12 and a control valve plugging cover 13, a check valve mounting hole and a control valve mounting hole are disposed on a mounting side 112 of the valve body 11, the check valve plugging cover 12 is plugged at an orifice of the check valve mounting hole to form a check valve chamber 41, the control valve plugging cover 13 is plugged at an orifice of the control valve mounting hole to form a control valve chamber 42, the first elastic member 60 abuts between the check valve plugging cover 12 and the check valve core 50, and the second elastic member 80 abuts between the control valve plugging cover 13 and the control valve core 70. The structure is simple, the check valve plugging cover 12 plays a role of limiting the check valve core 50, and the control valve plugging cover 13 plays a role of limiting the control valve core 70.
As shown in fig. 4 and 5, in the present embodiment, the check valve mounting hole includes a first large diameter section and a first neck-reducing section, a mouth of the first neck-reducing section far from the first large diameter section forms the first valve port 48, a hole wall of the first neck-reducing section is a first tapered surface 411, the check valve core 50 has a second tapered surface adapted to the first tapered surface 411, and a first annular sealing ring 90 is disposed between the first tapered surface 411 and the second tapered surface.

The above structure prevents the fire extinguishing agent from entering the first communication passage 43 and the fire detecting pipe connection passage 44 when the control valve spool 70 is moved to the second open position, and prevents the fire extinguishing agent from being discharged from the fire detecting pipe joint 140. The second space is actually formed by a portion above the first annular seal 90 of the check valve chamber 41, a portion above the third annular seal 110 of the control valve chamber 42, the first communication passage 43, and the flame path connection passage 44.

Specifically, a seal ring mounting groove is provided on an outer side wall of the control valve spool 70, and a third annular seal ring 110 is disposed in the seal ring mounting groove. When the control valve spool 70 is fitted into the control valve mounting hole, the position where the control valve mounting hole is connected to the first communication passage 43 and the fire detecting pipe connection passage 44 may severely compress the third annular seal ring 110, causing the third annular seal ring 110 to be damaged and thus not sealing. Therefore, the chamfer 422 is added, so that the third annular seal ring 110 can smoothly slide into the lower hole section through the chamfer 422, and the ring cutting phenomenon is prevented from being generated.

A closed space is formed between the installation recess 51 and the wall of the check valve chamber 41, which results in the need for compressed air during the upward movement of the check valve spool 50, resulting in difficulty in the upward movement of the check valve spool 50. In order to solve the above problem, as shown in fig. 4 and 5, in the present embodiment, a plurality of relief holes 52 communicating with the mounting groove 51 are provided on the outer sidewall of the check valve spool 50. The structure enables the gas between the installation groove 51 and the cavity wall of the check valve cavity 41 to be discharged through the plurality of air release holes 52 in the process of moving the check valve core 50 upwards, so that the gas is quickly expelled, and the smoothness of the upward movement of the check valve core 50 is improved.
As shown in fig. 9 to 11, the present application provides a valve block, an embodiment of the valve block according to the present application includes: the fire detection pipe comprises a plurality of valve modules 190 arranged in parallel, wherein the valve modules 190 are the valve modules, the installation planes 111 of two adjacent valve modules 190 are opposite, the fire detection pipe starting main pipes 20 of two adjacent valve modules 190 are communicated, and the fire extinguishing agent spraying main pipes 30 of two adjacent valve modules 190 are communicated. The valve group formed by splicing the valve modules 190 has the advantages of simple structure, high reliability and low cost.
Several points need to be explained in further detail below:
1. the starting joint 120 and the fire extinguishing agent pipe joint 130 of the valve block are firmly connected with the container valve and the release pipe of the fire extinguishing storage bottle, respectively. When the pressure in the fire extinguishing storage bottle is introduced into the check valve chamber 41, the check valve core 50 is pushed upward by the pressure until the pressure is attached to the check valve plugging cover 12, the pressure in the check valve chamber 41, the portion of the control valve chamber 42 above the third annular sealing ring 110, the fire detecting pipe connecting channel 44 and the fire detecting pipe in the protection area connected to the fire detecting pipe connecting channel 44 are consistent, and at this time, the check valve core 50 moves downward by the pressure of the first elastic member 60 until the pressure is attached to the valve body 10, so that the pressures in the first space and the second space are independent of each other.
2. After the pressures of the check valve chamber 41, the portion of the control valve chamber 42 above the third annular sealing ring 110, the fire detecting pipe connecting passage 44, and the fire detecting pipe in the protection zone connected to the fire detecting pipe connecting passage 44 are the same, the control valve core 70 of the passage where the fire detecting pipe in the protection zone is not softened and exploded is fixed by the elastic force of the second elastic member 80 and the pressure of the portion of the control valve chamber 42 above the third annular sealing ring 110.
3. The fire detecting pipe in a certain protection area is softened and exploded, so that the pressure of the part above the third annular sealing ring 110 of the check valve chamber 41 and the control valve chamber 42, the pressure of the fire detecting pipe connecting passage 44 and the pressure of the part of the fire detecting pipe in the protection area connected with the fire detecting pipe connecting passage 44 are quickly leaked, the check valve spool 50 is quickly pushed by the pressure in the fire detecting pipe starting main pipe 20, the pressure is leaked, the container valve is opened, the fire extinguishing agent starts to be sprayed along the fire extinguishing agent spraying main pipe 30, the control valve spool 70 of the channel softened and exploded by the fire detecting pipe is pushed to move upwards, and the fire extinguishing agent starts to be sprayed.
An example is described in detail below:
the first elastic member has a size of 0.8 × 8 × 15 (mm), an elastic force of 12N in an initial state, and an elastic force of 22N after being compressed;
the second elastic member has a size of 1.2 × 10 × 30 (mm), an elastic force of 19.5N in an initial state, and an elastic force of 58N after being compressed;
if the volume of the gas cylinder is 3L, the filled perfluorohexanone is 3Kg, and the filled pressure is 2.5MPa.
After the fire detecting tube in a certain protection area is softened and exploded, the cross section area of the pressure applied to the check valve core 50 of the corresponding channel by the gas cylinder at one moment is 70.88mm 2 The pressure in the gas cylinder is 2.5MPa, and 1.6MPa after the pressure is reduced by the container valve, so the pressure entering the check valve chamber 41 is 1.6MPa, the instant force is 113N, which is far greater than the elastic force of the spring, and the check valve core 50 can be pushed quickly.
The channel without fire extinguishing agent is not sprayed, the control valve core 70 is not moved, at this time, the part above the third annular sealing ring 110 of the control valve chamber 42 is kept consistent with the pressure in the check valve chamber 41 and is 1.6MPa, the size of the second elastic part is 1.2 x 10 x 30 (mm), the elastic force is 19.5N in the initial state, and therefore the cross section area of the pressure applied to the top of the control valve core 70 is 314.16mm 2 Force given by gas294.52N, and 313.65N together with the spring force.
After the fire detecting tube in a certain protection area is softened and blasted, the sectional area of the pressure applied to the control valve core 70 of the corresponding channel by the gas cylinder at one moment is 70.88mm 2 The pressure in the gas cylinder is 2.5MPa, the instantaneously received force is 177N, and the valve core 70 of the control valve in the channel which is not sprayed can not be pushed.
As long as the check valve core 50 moves, the fire extinguishing agent pushes the control valve core 70 to be sprayed all the time, so that the force applied to the control valve core 70 after the fire extinguishing agent is sprayed is calculated at last.
After the fire extinguishing agent is sprayed, according to the ideal gas state formula, the pressure in the gas cylinder is 0.94MPa, and the cross section area of the valve core 70 of the control valve under the pressure in the gas cylinder is 314.16mm 2 The thrust force is 295N, which is much larger than the elastic force of the spring, so the valve core 70 of the control valve is always in the state of being attached to the blocking cover 13 of the control valve in the process of spraying the fire extinguishing agent.
The present application also provides a fire extinguishing apparatus, an embodiment of a fire extinguishing apparatus (not shown in the figures) according to the present application comprising: the fire extinguishing device comprises a fire extinguishing storage bottle, a valve group, a fire detecting pipe and a spray head. Wherein, the storage bottle of putting out a fire includes the bottle body and sets up container valve and the release pipe on the bottle body. The valve group is the valve group, the fire detecting pipe starting main pipeline 20 of the valve group is connected with the container valve, and the fire extinguishing agent spraying main pipeline 30 of the valve group is connected with the releasing pipe. The flame probe tube communicates with the flame probe tube connection channel 44 of the valve block. The spray head communicates with a spray head connection channel 45 of the valve block. Because above-mentioned valves have simple structure, the reliability is high, advantage with low costs, consequently the extinguishing device who has it also has above-mentioned advantage.
