Description

Technical part

The utility model relates to the technical area of the fire extinguishing system, specifically to a heptafluoropropane gas fire extinguishing system based on a pipeline system.

State of the art

Heptafluoropropane is a chemical fire extinguishing agent with clean gas. It mainly has a function of chemical fire extinguishing, but also a function of physical fire extinguishing. Heptafluoropropane can reliably extinguish class B and C fires and electrical fires with a low extinguishing concentration. It stands out for its small storage space, high critical temperature and low critical pressure and can be stored in liquid form at room temperature. It does not contain any particles or oily residues after release and has no destructive effect on the atmospheric ozone layer (ODP value is zero). The retention time of this extinguishing agent in the atmosphere is 31 to 42 years, which corresponds to environmental protection requirements.

According to the prior art, fire extinguishers are generally used by personnel to extinguish the fire at the focal point, which increases the workload of the personnel and poses a higher risk. In addition, the effect is bad.

Content of the utility model

In order to overcome the above-mentioned deficiencies in the prior art, the utility model provides a pipe network-like heptafluoropropane gas fire extinguishing system. The technical problems that are to be deleted in this utility model are the high degree of limitation and great workload when using the fire extinguishing system.

In order to achieve the above goal, the following technical scheme is offered in this utility model: A heptafluoropropane gas fire extinguishing system based on a pipeline system, consisting of a steel bottle rack and a fire extinguisher bottle, with the fire extinguisher bottle attached to the steel bottle rack. The outlet side on the top of the fire extinguisher bottle is connected to a shut-off valve, the outlet side of which is in turn connected to a collecting line. The outlet side of the manifold is connected to one side of the high pressure hose, while the other side of the high pressure hose is connected to the inlet side of the pipe network, the outlet side of the pipe network being connected to a nozzle. A pump drive and a safety valve are set up on the high-pressure hose, the safety valve being located on the pump drive. The shut-off valve, the pump drive and the multi-way valve are all electronically connected to a gas fire extinguishing control panel by a wire. The gas fire extinguishing control panel is also electronically connected by a wire with a fire detector and an emergency stop / on button.

In addition, the ventilation of the fire extinguishing surface is controlled by the gas fire control panel, which contributes to the realization of the automatic transport of the extinguishing agent in the fire extinguisher bottle and the fire extinguishing of the focal point. This leads to a high degree of automation, simple operation, a lower workload and a high level of safety in use.

In a preferred embodiment, more than two multi-way valves are provided on the pipe network, each corresponding to more than two nozzles, which facilitates the opening and closing of the several nozzles by several multi-way valves.

In a preferred embodiment, more than two nozzles are set up, all of which are connected to the pipe network by a coupling hose, which makes it easier to extinguish several focal points using several nozzles.

In a preferred embodiment, more than two groups of the high pressure hose, the pump drive and the safety valve are available, the groups of the high pressure hose all being located between the collecting line and the pipe network. In addition, the groups of the high-pressure hose correspond to the groups of the pump drive and the groups of the safety valve, which facilitates the transport of the extinguishing gas in the fire extinguishing surface through several high-pressure hoses and prevents damage to the high-pressure hose and leads to a high level of safety when the gas is released.

In a preferred embodiment, more than two fire extinguishing bottles are provided, which (2) are all fixed by a fastening part on the steel bottle rack, which makes it easier to place several fire extinguishing surfaces and increases the scope of fire extinguishing and extends the extinguishing time.

In a preferred embodiment, the underside of the steel bottle rack has a base plate which is fixed to the steel bottle rack by a fastening part, which increases the stability when the steel bottle rack is placed.

In a preferred embodiment, the gas fire extinguishing control panel is electronically connected by a wire to an alarm regulator, which in turn is electronically connected by a wire to a sound and light alarm, which can remind the staff by operating the alarm and contribute to a safe withdrawal of the staff.

In a preferred embodiment, the gas fire extinguishing control panel is electronically connected to a release label by a lead wire, which makes it easier to view the operation of the release label and can view and control the ventilation of the fire extinguisher bottle.

As the 1-7 show the specific embodiment looks like this: The heptafluoropropane gas fire extinguishing system based on a pipeline system mainly consists of a fire alarm control unit (including the fire alarm 13th , the alarm controller 14th , the gas fire control panel 12th , the sound and light alarm 15th , the release mark 16 and the emergency stop / on button 11 ) and fire extinguishing system unit (including the gas fire extinguisher 2 , the steel bottle rack 1 , the shut-off valve 3 , the manifold 4th , the safety valve 5 , the pump drive 6th , the high pressure hose 7th , the multi-way valve 8th , the pipe network 9 and the nozzle 10 ). There are three ways to start the system: electric start, manual start and mechanical emergency start. The system can be divided into two types: Fire extinguishing system with the pipeline system 9 and fire extinguishing system without the piping system 9 . The fire extinguishing system with the pipeline system 9 is divided into a unit-independent system and a combined distribution system. Unit-independent system: One source of supply for heptafluoropropane fire extinguishing agents through a fixed network of pipes 9 and a nozzle 10 to protect a protected area or a protected object. Combined distribution system: One source of supply for heptafluoropropane fire extinguishing agents through a partial multi-way valve 8th , a solid network of pipes 9 and a nozzle 10 to protect two or more protected areas or protected objects.

When the fire alarm 13th sends out a fire signal in the protected area and sends the fire signal over the power wire to the gas fire extinguishing control panel 12th is transmitted, the gas fire control panel delays 12th zero to 30 seconds and then sends a telecommunication command to the appropriate fire extinguisher 2 to be activated according to the pre-combined distribution procedure. Then the multi-way valve 8th and the corresponding shut-off valve 3 opened to the pump drive 6th operate at the same time. Then drive the pump drive 6th to help the fire extinguisher vaporize. The gas flows along the manifold 4th and the pipe network 9 and finally through the nozzle 10 and blow out what automatic fire extinguishing does.

Description of the manual start principle: When the fire detector 13th If a fire signal is emitted in area A or a fire is visually recognized, the gas fire control panel falls 12th out. The magnetic insurance is then pulled out manually and the pen is printed. Then the appropriate fire extinguisher 2 open. The high pressure N2 in the bottle opens the corresponding multi-way valve 8th and the shut-off valve 3 and put out the fires in area A; if the fire alarm in area B sends out a fire signal or a fire is visually recognized, the gas fire extinguishing control panel falls 12th off and the magnetic insurance is removed manually. Then the pen is also pressed and the corresponding fire extinguisher bottle is opened. The high pressure N2 in the bottle opens the corresponding multi-way valve 8th and the shut-off valve 3 and every two or more groups of the fire extinguisher 2 to put out the fires in area B. The starting principle of the spare steel bottle rack and the spare fire extinguisher bottle is the same as above.

Mechanical emergency start: If the electric start or the manual start fails, the staff can use the appropriate multi-way valve 8th and manually open the cylinder valve at the point to extinguish the fire. With the emergency stop / on button 11 the fire extinguishing system is stopped or started.
