Description

A fire pump integration system having a discharge pipe with an integrated performance test discharge function and a fire pump with seismic performance used in the integrated system {A Fire Fighting Pump Integration System Have A Integrated Test And Discharge Function Outlet Pipe and A Fire Fighting Pump With Earthquake-Proof Function Using Thereof}

The present invention relates to a fire pump integrated system having a discharge pipe with an integrated performance test discharge function and a fire pump with seismic performance used in the integrated system. More specifically, it relates to a fire pump that can perform the performance test pipe and discharge pipe functions at the same time. It relates to a fire pump integrated system having a discharge piping with an integrated performance test function and a discharge function, and a fire pump with seismic performance used in the integrated system.

Fire pumps are installed in buildings such as apartments, buildings, shopping malls, and factories to prepare for fires. In the event of a fire, the fire pump pressurizes the water flowing in from the water supply pipe to a preset pressure and supplies it to sprinklers or other fire extinguishing nozzles.

The fire pump is a main pump that pressurizes and discharges water while operating in the event of a fire, a backup pump that pressurizes and discharges water separately from the main pump when a problem occurs in the main pump or when necessary, and a top pressure pump that maintains the pressure in the fire piping at a certain level. Includes pump.

Since fire pumps are constructed inside buildings, the installation space must be minimized, and the suction pipe and discharge pipe are connected to the main pump, spare pump, and pressure pump to operate only when a fire occurs. Therefore, fire pumps installed in most buildings last for several years. Since the standby state is often maintained for decades to decades, tests are required periodically to check whether the fire pump placed on standby for a long period of time operates normally in the event of an actual fire, and whether the fire pump operates normally.

In addition, because it must remain in standby mode for a long time, seismic performance that is not affected by recent frequent earthquakes or surrounding shocks is required.

If you operate the fire pump and open the sprinkler for a normal test, the internal fixtures and equipment may become wet and cannot be used or function normally. Therefore, the fire pump must be operated without opening the sprinkler, but in this case, the fire piping As the internal pressure increases rapidly, fire extinguishing pipes and related facilities may be damaged.

To solve these problems, various studies are being attempted to test the normal operation of fire pumps that are earthquake-resistant and efficient while taking up less installation space.

1, 2, and 3, the fire pump integrated system 100 having a discharge pipe with an integrated performance test discharge function of the present invention includes a seismic board 110 on which the pump and control panel can be installed in an integrated manner. There is.

The earthquake-resistant board 110 is composed of an installation part using a steel plate to install the pump and control panel, and a connection part to connect and assemble the board on which the pump and control panel are installed to the floor inside the building. Although not shown, damage to the pump can be prevented by inserting a spring that absorbs or alleviates earthquake vibration, or an EPDM earthquake-resistant pad that absorbs vibration, into the earthquake-resistant substrate.

The main pump 120, which is fixedly installed on the earthquake-resistant substrate 110, pressurizes and discharges water while operating in the event of a fire, and the spare pump 130 supplies water separately from the main pump when an abnormality occurs in the main pump or when necessary. It is pressurized and discharged, and the pressure pump 140 is a pump that maintains the pressure in the fire extinguishing pipe at a constant level.

The pressure pump 140 operates to keep the pressure in the fire extinguishing pipe constant according to the instructions of the control panel 180 based on the data from the electronic pressure switch 174.

The control panel 180 supplies power to the main pump 120, the spare pump 130, and the filling pump 140, monitors and controls work instructions and operating status, and controls the main pump 120, the spare pump 130, It has the function of remotely notifying the person in charge of the work instructions and operating status of the pressure pump 140. If necessary, the control panel 180 can be installed and assembled at a distance from the pumps.

In addition, the control panel 180 can programmatically operate the main pump 120, spare pump 130, charge pump 140, and various open/close valves to check their operating status periodically and as needed.

In addition, the control panel has a function to remotely notify the person in charge, so firefighting facility inspections can be performed anytime, anywhere, not only on site but also in a digital environment.

The suction pipe 150 that receives water is connected to a water storage tank or firefighting water supply pipe (not shown), and a plurality of suction branch pipes ( 151a, 151b, 151c), and at the area connected to the fire water supply pipe (not shown), there is a seismic groove joint 155 with anti-seismic packing 156 and a connection flange 158. On the opposite side, a groove cap 153 is installed to block the suction pipe 150.

Opening and closing the passages of a plurality of suction branch pipes (151a, 151b, 151c) branched from the suction pipe 150 and connected to the suction side of the main pump 120, the spare pump 130, and the filling pump 140, respectively. Suction open/close valves (152a, 152b, 152c) are installed in the suction branch pipes (151a, 151b, 151c).

The front discharge pipes (160, 160a) have a plurality of discharge branch pipes (161a, 161b, 161c) connected to the discharge side of the main pump (120), spare pump (130), and filling pump (140), and are equipped with anti-seismic packing. An electronic pressure switch (174) connects the groove cap (153) and the lower branch tee (165a) with a seismic groove joint (155), and generates an on/off signal by detecting the pressure of the discharged water and comparing it to a preset pressure. ) and a pressure-sensing drain valve 172 that opens and closes the pressure-sensing pipe 170.

The electronic pressure switch 174 in the front discharge pipes 160 and 160a is installed in the pressure sensing pipe 170 and is configured to generate a signal according to the pressure of water flowing into the pressure sensing pipe 170.

Meanwhile, the electronic pressure switch 174 may be configured to generate an off signal when the pressure of the inflow water reaches a preset pressure, and to generate an on signal when the pressure of the inflow water does not reach the preset pressure. . By applying this principle, the pressure status of the front discharge pipes (160, 160a) can be known. Based on this data, the control panel (180) instructs the filling pump (140) based on the data of the electronic pressure switch (174). It can operate to keep the pressure in the fire extinguishing pipe constant.

Opens and closes the flow path of the discharge branch pipes (161a, 161b, 161c), and prevents water from the discharge branch pipes (161a, 161b, 161c) from flowing back into each pump. Integrated check valve ball valves (162a, 162b, 162c) are installed.

Pressure gauges (164a, 164b) that indicate and control the pressure of the pump in the discharge branch pipes (161a, 161b) connected to the integrated check valve ball valves (162a, 162b) in the main pump (120) and the spare pump (130), respectively. and relief valves 163a and 163b are installed.

In addition, there is a function to install a pressure gauge on the check valve ball valves (162a, 162b, 162c) used in the present invention, so the pressure gauge can be installed on the integrated check valve ball valve.

The side discharge pipe (160b) is vertically connected to the front discharge pipe (160a) using a lower branch tee (165a), and includes an opening/closing valve (166) that opens and closes the discharged flowing water, and a flow meter (167) that measures the flow rate. ), a flow control valve 168 that controls the amount of water, and the discharge port of the flowing water is connected to a flange and has a discharge opening/closing valve 169. The discharge open/close valve (169) is normally open to maintain a constant pressure within the fire pipe, and is closed only during performance tests. It is then connected to the upper branch tee (165b) and is a drain valve that selectively receives discharged water and discharges it to the outside. (159) is used to test the performance while discharging.

The front discharge pipe (160a) and the side discharge pipe (160b) are connected to the lower branch tee (165a), and an opening/closing valve (166), a flow meter (167), and a flow control valve (168) are installed to control the flow rate during pump experiments. Adjust and drain through the drain valve 159 connected using the upper branch tee (165b).

According to the Fire Service Act, looking at the location and distance relationship of the on-off valve (166), the flow meter (167), and the flow control valve (168), based on the flow meter (167), the on-off valve (166) and the flow meter (167) are connected to the pipes used. It is specified that they are located at a distance of 8 times the diameter, and the flow meter (167) and the flow control valve (168) are located at a distance of 5 times the diameter of the pipe being used.

When designing the positions of the on-off valve (166), flow meter (167), and flow control valve (168) in accordance with these fire protection laws, the commonly used 100mm and 150mm diameter pipes are installed on the on-off valve (166), flow meter (167), and Since the flow control valve (168) is located vertically, there is no problem in using the discharge opening/closing valve (169), but when using a large pipe of 200 mm or more, it must be designed with a distance of more than 2 m, which causes some inconvenience in use. Therefore, the front discharge pipe (160a) and the side discharge pipe (160b) are designed horizontally in a (■) shape as shown in the red drawing direction of Figure 1, and the discharge opening/closing valve (169) is installed on the side. ), a drain valve (159) can be installed.

In addition, when using the discharge on/off valve (169) as an electronic on/off valve, there is no problem even if it is designed vertically when using a large pipe.

The side discharge pipe drain valve 159 has a pipe (not shown) that discharges water to the outside during a functional test.

The lateral discharge pipe (160b) also has a plurality of earthquake-resistant groove joints (155) and protects the fire pump integrated system (100) by absorbing vibration of the building or vibration caused by an earthquake.

The seismic groove joint 155 has a seismic packing 156 with an earthquake prevention function and a water leak prevention function, and the seismic groove joint 155 has a connection function with a lap joint 157 and a flange 158.

The integrated check valve ball valves 162a, 162b, and 162c have both a check valve function and a ball valve function.

All of the above on/off valves may include remote control electronic on/off valves.

The fire pump integrated system having a discharge pipe with an integrated performance test discharge function of the present invention described above can perform the performance test and discharge function with a single discharge pipe, so there is no need to install a separate performance test device, and it is easy to assemble. , the installation space may be small. In addition, it has a good earthquake-resistant structure, making it resistant to earthquakes and shock vibrations.

In addition, fire management can be performed in accordance with the hyper-connected social system that is connected anytime and anywhere according to the digital environment.

Figure 4 is a front view of a fire pump with earthquake-resistant performance of the present invention.

Figure 5 is a photograph of a fire pump with earthquake-resistant performance of the present invention.

When explained with reference to FIGS. 4 and 5, the fire pump is a fire pump used in the fire pump system having a discharge pipe with an integrated performance test discharge function, as described above. Since all structures and principles are the same, redundant explanations are not provided.

Unless it is just an unusual part, I would like to explain in detail only the parts that are lacking in the fire pump system that has a discharge piping with a front integrated performance test discharge function.

Since the fire pump system is installed inside a building, it can be installed partially while repairing existing facilities, or installed all together in a new building.

In these cases, the entire system is newly constructed, or only partial parts are repaired, and partial parts account for a large portion of product sales.

Figures 4 and 5 show the fire pump portion, excluding the lateral discharge pipe (160b) in the fire pump integrated system having a discharge pipe with an integrated performance test discharge function. Since it has already been explained above, I will not explain the overlapping parts and explain why the side discharge pipe (160b) was excluded.

The existing building already has a structure in which the discharge pipe and performance test tube are separated. In order to improve the performance of the fire pump in this old facility structure, only the fire pump needs to be replaced. In this case, when the fire pump installer wants to install the existing facility while making use of it, he or she may replace only the fire pump and use the discharge pipe or performance test tube as is.

In this case, the fire pump of the present invention may be applied and used as is. It can be connected using a branch tee as shown in Figure 4, or it can be combined with existing equipment using a flange and L-shaped elbow joint as shown in Figure 5.

In general, the existing discharge piping is operated with the discharge piping valve open, so there is no problem. During the performance test, the opening/closing valve at the top of the existing discharge pipe is closed and the existing performance test pipe is opened and the performance test is performed. Therefore, the fire pump of the present invention can be used in applications like existing systems.

Figure 6 is a diagram of a discharge pipe with an integrated performance test discharge function of the present invention.

When explained with reference to FIG. 6, the fire discharge pipe is a discharge pipe used in the fire pump integrated system having a discharge pipe with an integrated performance test discharge function, as described above. Since all structures and principles are the same, redundant explanations are not provided.

I would like to explain in detail only the unusual parts that were insufficient in the previous explanation.

According to the Fire Service Act, looking at the location and distance relationship of the on-off valve (166), the flow meter (167), and the flow control valve (168), based on the flow meter (167), the on-off valve (166) and the flow meter (167) are connected to the pipes used. It is specified that they are located at a distance of 8 times the diameter, and the flow meter (167) and the flow control valve (168) are located at a distance of 5 times the diameter of the pipe being used.

When designing the positions of the on-off valve (166), flow meter (167), and flow control valve (168) in accordance with these fire protection laws, the commonly used 100mm and 150mm diameter pipes are located within a distance of 2 m. Since the flow control valve (168) is located vertically, there is no problem in using the discharge opening/closing valve (169). At this time, the design only needs to be produced by selecting the black dotted area A.

When using large pipes of 200 mm or more, they must be designed at a distance of 2 m or more, which may cause some inconvenience in use. Therefore, the side discharge pipe (160b) must be connected to the front discharge pipe (160a) by selecting the red dotted line B area. The side discharge pipe (160b) can be designed horizontally, and the drain valve (159) and discharge opening/closing valve (169) can be installed on the side.

Therefore, it can be manufactured by selecting area A vertically or area B horizontally depending on the size of the pipe and the installation environment.

Figure 7 is a diagram of a control panel used in the present invention.

Figure 8 is a photograph of the control panel used in the present invention.

7 and 8, the control panel is a control panel used in the fire pump integrated system having a discharge pipe with an integrated performance test discharge function, as described above. Since all structures and principles are the same, redundant explanations are not provided.

The control panel 180 concept used in the present invention supplies power to the main pump, reserve pump, and fill-up pump, monitors and controls work instructions and operating status, and monitors work instructions and operating status of the main pump, spare pump, and fill-up pump. It has the function of remotely notifying the person in charge.

In addition, the control panel can programmatically operate the main pump, spare pump, charge pump, and various open/close valves to check their operating status periodically and as needed.

In addition, the control panel has a function to remotely notify the person in charge, so firefighting facility inspections can be performed anytime, anywhere, not only on site but also in a digital environment.

Existing fire pump facilities can also be applied and improved by changing several on-off valves and electronic pressure switches (174) and changing the control panel in existing facilities.

Figure 9 is a photograph and front cross-sectional view of an integrated check valve ball valve used in the present invention to open and close the discharge branch pipe and prevent backflow of water.

Figure 10 is a drawing and photograph of a connecting member for a fire pump set used in the present invention.

9 and 10, it is an integrated check valve ball valve and connection member used in the fire pump system having a discharge piping with an integrated performance test discharge function, as described above. Since all structures and principles are the same, redundant explanations are not provided.

The integrated check valve ball valve 162 shown in Figure 9 is an integrated check valve ball valve invented by the inventor of the present invention and registered as patent registration number 10-1863038.

The integrated check valve ball valve is an integrated one in the existing fire pump where the on-off valve and check valve are installed separately, so it is easy to assemble the pump and the space extending to the side is required to be small, and the cost of parts and materials is reduced, which innovatively reduces labor efficiency as well as product cost. By improving it, a cheap pump can be provided.
Figure 10 shows seismic resistance using a seismic groove joint (155) when connecting each part or pipe.
It can achieve both water protection and water leak prevention functions at the same time. (See Figures 1, 2, and 3)
In the pipes 150 and 160 that supply or discharge water, the seismic groove joint 155, which has an earthquake-resistant packing 156 with an earthquake-proof function and a water-leakage prevention function, is inserted into the pipe that supplies or discharges water, and is an earthquake-resistant The lap joint 157, which has an inner surface into which the packing 156 is inserted and has a ring-shaped groove, is connected and fastened to the pipes 150 and 160 or the branch tee 165, and is tightened using a flange 158. Combine and conclude using the structure.
The above earthquake-proof packing material is EPDM (Ethylene Propylene Diene Monomer).
It has waterproof and earthquake-proof functions at the same time.
The earthquake-resistant packing (156), which has an earthquake-proof function and a water-leakage prevention function, is located on the inner surface of the earthquake-resistant groove joint of the earthquake-resistant groove joint (155) and is connected to piping (150, 160), lap joint (157), and piping (150, 160) on both sides. Alternatively, the branch tee 165 is inserted to surround and compress the earthquake-resistant groove joint 155, and the elastic force of the EPDM material, which is the material of the earthquake-resistant packing 156, serves to cushion vibration.
Therefore, the seismic groove joint 155 can connect horizontal or vertical structural components and perform a buffering function.
