Description

Technical Field

[0001] The invention relates to the technical field of kitchen fire protection systems, and in particular to a fire extinguishing agent container with a liquid level display function. Background Art

[0002] The kitchen is an important place, and fire safety has always been a key concern of catering companies and relevant inspection departments. The kitchen is a place where oil smoke and fire accidents are prone to occur. In addition to being fully equipped with cooking equipment, a qualified kitchen also needs to be equipped with a full set of kitchen fire extinguishing systems.

[0003] The kitchen fire extinguishing system can effectively control kitchen fires caused by high-temperature oil pans. It consists of fire extinguishing agent containers, pipe networks, control systems, valves, detectors and other devices. The specific working principle is that after the oil pan on the kitchen stove burns, the huge heat emitted by the flame causes the temperature-sensitive fusible metal cable releaser to detach; the temperature-sensitive detection system opens the release device of the kitchen fire extinguishing system, pressurizes the fire extinguishing agent container, and simultaneously activates all auxiliary starting or electric cutting devices and alarm linkage devices. The fire extinguishing agent in the fire extinguishing agent container is sprayed on the surface of the kitchen stove equipment and the exhaust hood, oil filter net and exhaust pipe through the pipe network. This special fire extinguishing agent can quickly extinguish the flame in the oil pan and form a covering layer to inhibit the combustion of oil vapor to prevent the oil from re-igniting.

[0004] As a device for storing fire extinguishing agent, the storage amount of fire extinguishing agent in the fire extinguishing agent container is crucial. Since the fire extinguishing agent in the fire extinguishing agent container will evaporate (the temperature in the kitchen is high), the current fire extinguishing agent container cannot observe the amount of fire extinguishing agent in the container. When the fire extinguishing agent evaporates to a small volume, if it is not replenished in time, the fire extinguishing effect of the kitchen fire extinguishing system will be seriously affected when it is working.

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0022] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0023] Example 1

[0024] like Figure 1As shown, in this embodiment, a fire extinguishing agent container with a liquid level display function is provided, including a storage tank 1, a liquid level display gauge 2 and two connectors, the two connectors are longitudinally distributed, a discharge hole 3 is opened on the top of the storage tank 1, a pipe joint 4 is connected to the discharge hole 3, and the top and bottom of the inner cavity of the liquid level display gauge 2 are connected to the inner cavity of the storage tank 1 through the two connectors respectively.

[0025] During use, since the top and bottom of the inner cavity of the liquid level display gauge 2 are connected to the through hole 5 through two connectors, and then connected to the inner cavity of the storage tank 1, the fire extinguishing agent in the inner cavity of the storage tank 1 can enter the inner cavity of the liquid level display gauge 2, so that the capacity of the fire extinguishing agent in the inner cavity of the storage tank 1 can be observed through the liquid level display gauge 2. When the capacity of the fire extinguishing agent is too low, it is replenished in time to prevent the fire extinguishing agent capacity from being insufficient when the kitchen fire extinguishing system is working and seriously affecting the fire extinguishing effect.

[0026] Example 2

[0027] This embodiment is further described on the basis of embodiment 1. Figure 2 As shown, the connector described in this embodiment includes a connecting tube 61, a connecting column 62 and a first closing bead 63. The connecting tube 61 has a rear wall, and a connecting hole 64 is opened on the rear wall of the connecting tube 61. The connecting hole 64 is connected to the inner cavity of the storage tank 1. The rear part of the connecting column 62 enters the connecting tube 61 and is connected to the inner wall of the connecting tube 61. The front part of the connecting column 62 enters or passes through the liquid level display gauge 2. A first circulation channel 65 is arranged in the connecting column 62. The first circulation channel 65 connects the inner cavity of the connecting tube 61 with the inner cavity of the liquid level display gauge 2. The first closing bead 63 is located between the connecting hole 64 and the first circulation channel 65. The diameter of the first closing bead 63 is larger than the diameter of the connecting hole 64 and the first circulation channel 65. In the initial state, the first circulation channel 65 is connected to the inner cavity of the connecting tube 61. When subjected to pressure from the storage tank 1, the first closing bead 63 can completely close the entrance of the first circulation channel 65.

[0028] When the kitchen fire extinguishing system is working, the fire extinguishing agent in the storage tank 1 is sprayed out with a very high pressure. Since the liquid level indicator 2 is made of glass, it cannot withstand the large pressure and is easily damaged. Once damaged, the fire extinguishing agent will spray out from the connector, causing the entire kitchen fire extinguishing system to fail to work properly.

[0029] In this embodiment, the connector includes a connecting pipe 61, a connecting column 62 and a first sealing bead 63. The connecting pipe 61 is connected to the storage tank 1, and the connecting column 62 enters the connecting pipe 61. A first circulation channel 65 is set in the connecting column 62, so that the inner cavity of the connecting pipe 61 is connected to the inner cavity of the liquid level display meter 2. A first sealing bead 63 is set. The first sealing bead 63 is set between the connecting hole 64 and the first circulation channel 65. The first sealing bead 63 can move. When the fire extinguishing system is not working, the first circulation channel 65 is connected to the inner cavity of the connecting pipe 61. At this time, the fire extinguishing agent normally enters the liquid level display meter 2. When the fire extinguishing system is working, the huge pressure generated by the fire extinguishing agent in the storage tank 1 pushes the first sealing bead 63 to move forward to completely close the entrance of the first circulation channel 65. At this time, the fire extinguishing agent no longer enters the liquid level display meter 2, but is only discharged from the discharge hole 3. This prevents the leakage of fire extinguishing agent caused by damage to the liquid level display meter 2 and the failure of the kitchen fire extinguishing system.

[0030] In this embodiment, the first sealing bead 63 is in contact with the bottom wall of the connecting hole 64 and the bottom wall of the entrance of the first circulation channel 65 at the same time, and there is a gap between the first sealing bead 63 and the top wall of the connecting hole 64 and the top wall of the first circulation channel 65. In this way, when the first sealing bead 63 is subjected to the pressure from the storage tank 1, the first sealing bead 63 can close the entrance of the first circulation channel 65 in time due to the position restriction of the first circulation channel 65 and the connecting hole 64.

[0031] In this embodiment, there are two ways to connect the connecting hole 64 with the inner cavity of the storage tank 1. One is that two through holes 5 are opened on the side wall of the storage tank 1, and the rear wall of the connecting pipe 61 is connected to the outer wall of the storage tank 1, and the two connecting holes 64 are connected to the two through holes 5 respectively; the other is that the connecting pipe 61 directly enters the inner cavity of the storage tank 1. In this way, the liquid level display meter 2 can be embedded in the outer wall of the storage tank 1, making the product more beautiful.

[0032] In this embodiment, the first sealing bead 63 is a steel bead, and the connecting tube 61 and the connecting column 62 are both made of pressure-resistant material.

[0033] In this embodiment, the rear portion of the connecting column 62 is threadedly connected to the inner wall of the connecting pipe 61 , which facilitates the installation of the connecting column 62 and the connecting pipe 61 .

[0034] In this embodiment, a first elastic sealing gasket 66 is provided between the connecting pipe 61 and the liquid level display gauge 2 . The first elastic sealing gasket 66 completely seals the connecting pipe 61 and the liquid level display gauge 2 to prevent the fire extinguishing agent from leaking from between the connecting pipe 61 and the connecting column 62 .

[0035] In this embodiment, the connecting column 62 movably penetrates the liquid level display gauge 2, and the rear end of the connecting column 62 is connected to a fixed head 67. A second elastic sealing gasket 68 is arranged between the fixed head 67 and the liquid level display gauge 2, so that the installation of the connecting column 62 can be facilitated. The fixed head 67 and the second elastic sealing gasket 68 are arranged at the same time to prevent the fire extinguishing agent from leaking from between the liquid level display gauge 2 and the fixed head 67.

[0036] In this embodiment, the side of the components in the connector close to the storage tank 1 is the rear side.

[0037] Example 3

[0038] This embodiment is further limited on the basis of embodiment 1, such as Figure 3 As shown, the present embodiment also includes a second connector 71, the right portion of which enters into the pipe joint 4, a first groove 73 is formed on the right wall of the second connector 71, a second groove 75 is formed on the left wall of the second connector 71, the first groove 73 and the second groove 75 are connected via a through hole 74, the right portion of the second connecting column 72 enters into the second groove 75, a through hole 77 penetrating the left and right walls of the second connecting column 72 is formed, a second closing bead 76 is located between the second connecting column 72 and the through hole 74, the diameter of the second closing bead 76 is larger than the diameters of the through hole 74 and the through hole 77, in the initial state, the through hole 77 is connected to the inner cavity of the pipe joint 4, when the second closing bead 76 is subjected to pressure from the inner cavity of the pipe joint 4, the second closing bead 76 can completely close the right end of the through hole 77.

[0039] When the fire extinguishing system is working, the pipe network is connected above the pipe joint 4, and the discharge pipe is connected below the pipe joint. The discharge pipe passes through the discharge hole 3 and enters the storage tank 1. A one-way valve is provided at the connection between the pipe network and the pipe joint 4. When the kitchen fire extinguishing system is working, the one-way valve opens, and the fire extinguishing agent is discharged normally through the pipe joint 4 and the pipe network. The kitchen fire extinguishing system is in a closed state for a long time. When the kitchen fire extinguishing system is not working, the fire extinguishing agent will evaporate, and the evaporated fire extinguishing agent will leak from the one-way valve. At this time, the evaporated fire extinguishing agent will drip along the pipe network onto the kitchen countertop, pot, etc., causing pollution.

[0040] In this embodiment, a second connector 71 is provided, the second connector 71 enters into the pipe joint 4, a first groove 73 is provided on the right wall of the second connector 71, the first groove 73 is communicated with the inner cavity of the pipe joint 4, a second groove 75 is provided on the left wall of the second connector 71, the right part of the second connecting column 72 enters into the second groove 75, and a second sealing bead 76 is provided between the second connecting column 72 and the through hole 74, the second sealing bead 76 is movable, when the kitchen fire extinguishing system is not working, the second sealing bead 76 does not seal the right end of the through hole 77, at this time, the evaporated The fire extinguishing agent is discharged through the inner cavity of the pipe joint 4, the first groove 73, the through hole 74, the second groove 75 and the through hole 77, without causing pressure on the pipe joint 4 and the inner cavity of the pipe network, so that it will not leak from the one-way valve and fall into the pot or the kitchen countertop to cause pollution. When the kitchen fire extinguishing system is working, the second sealing bead 76 is subjected to the pressure from the inner cavity of the pipe joint 4, and the second sealing bead 76 moves to the left to completely close the right end of the through hole 77. At this time, the fire extinguishing agent is normally discharged from the pipe network, and the fire extinguishing agent will not be discharged from the through hole 77, thereby realizing the normal operation of the kitchen fire extinguishing system.

[0041] In this embodiment, the second sealing bead 76 is a steel ball.

[0042] In this embodiment, the right portion of the second connecting column 72 is threadedly connected to the inner wall of the second groove 75 , thereby facilitating the installation of the second connecting column 72 and the second sealing bead 76 .

[0043] In this embodiment, in the initial state, that is, when the kitchen fire extinguishing system is not working, the second sealing bead 76 is in contact with the bottom wall of the through hole 74 and the bottom wall of the through hole 77 at the same time, and there is a gap between the second sealing bead 76 and the top wall of the through hole 74 and the top wall of the through hole 77. In this way, due to the position restriction of the through hole 74 and the through hole 77 on the second sealing bead 76, when the second sealing bead 76 is subjected to the pressure from the inner cavity of the pipe joint 4, the second sealing bead 76 moves to the left to close the right end of the through hole 77 in time.

[0044] In this embodiment, the left end of the second connecting column 72 is located outside the second groove 75 .

[0045] In this embodiment, the second connector 71 is threadedly connected to the pipe connector 4 , which facilitates the installation of the second connector 71 .

[0046] In this embodiment, the diameter of the first groove 73 is greater than the diameter of the second groove 75 .
