Description

Siphon tube of gas-based fire extinguishing agent storage container

The present invention relates to a siphon tube suitable for the flat bottom surface of a gas-based fire extinguishing agent storage container. More specifically, the present invention relates to a gas-based fire extinguishing agent having a flat bottom so that it can be installed stably upright without auxiliary equipment such as a separate stand or pedestal. The siphon tube of the chemical storage container is formed with a two-stage joint that can be bent in multiple stages so that the lower part of the siphon tube can easily reach vertically to the edge of the bottom surface of the gas-based fire extinguishing agent storage container, so that the edge of the bottom surface of the container It facilitates the inhalation of the fire extinguishing agent remaining in the fire extinguishing agent and minimizes the remaining amount discharged. This improves economic efficiency and fire extinguishing performance through the efficient use of gas-based fire extinguishing agent, and provides auxiliary equipment and manpower for installing a storage container. This is about a siphon tube for a gas-based fire extinguishing agent cylinder that can reduce waste of time and improve price competitiveness.

In general, gas-based fire extinguishing agents are stored in a liquefied state at the bottom of the gas-based fire extinguishing agent storage container, which is a high-pressure container, and nitrogen, which is used as a pressure source for the release of the fire extinguishing agent, is stored under pressure at the top of the container, and the fire signal from the fire detector is generated. When the valve is activated and the release of the fire extinguishing agent begins, the fire extinguishing agent at the bottom of the container is proactively released due to the pressurization caused by the nitrogen accumulation pressure at the top of the container.

These gas-based fire extinguishing agent storage containers are divided into storage containers with a round bottom and storage containers with a flat bottom. A storage container with a round bottom has the advantage of reducing the remaining amount after discharge, but for stable installation, the use of auxiliary equipment such as a separate stand or stand is essential, making the installation work complicated and requiring additional installation manpower and time. There is a disadvantage that occurs, and in the case of a storage container with a flat bottom, stable installation is possible without a separate holder or pedestal, so the installation work is relatively simple, but there is a disadvantage that the remaining amount increases after discharge.

In this regard, Korea Registered Utility Model No. 20-0388086 (name: Integrated siphon tube for fire extinguisher, hereinafter abbreviated as 'Patent Document 1') has a device installed in the main body of the fire extinguisher to discharge the extinguishing agent filled in the main body. Technology regarding siphon tubes is known.

According to Patent Document 1 (see FIG. 1), the siphon tube (2) is installed inside the container (1) integrally with the valve for the purpose of preemptively discharging the fire extinguishing agent from a container with a round bottom, and this siphon tube is The upper part is installed integrally with the valve, and in order to solve the problem of remaining volume after discharge, the length of the siphon tube is lengthened and the lower part is as close to the bottom of the container as possible. The lower part has a tapered cross-section, so that the container moves when the valve is opened. Liquid fire extinguishing agent can be inhaled from the bottom and released through a valve at the top.

However, in Patent Document 1, the upper end of the siphon tube is installed integrally with the valve and is therefore disposed at the center along the longitudinal direction of the container, which inevitably creates a gap between the lower end of the siphon tube and the bottom surface of the container. As a result, there was a problem in that the fire extinguishing agent still remained on the bottom of the container even after the discharge of the fire extinguishing agent was completed.

Meanwhile, Republic of Korea Registered Utility Model No. 20-0422301 (name: Fire extinguishing device equipped with joint siphon tube, hereinafter abbreviated as 'Patent Document 2') contains fire extinguishing agent even when the main body of the fire extinguishing container is upright or lying down. There is a known technology that maximizes quality characteristics by releasing all of the residues.

According to Patent Document 2 (see FIG. 2), a first pipe (3a) connected to the discharge port (4), a connector (3c) that is made of a flexible material and functions as a joint, with one side coupled to the first pipe, and a connection By using the joint siphon tube (3), which consists of a second pipe (3b) that is coupled to the other side of the pipe and whose tip is always directed toward the ground regardless of the posture of the main body, the fire extinguishing container main body (1) can be used even in the upright or lying down state. It was possible to completely discharge the fire extinguishing agent (5).

However, in Patent Document 2 above, the lower part of the siphon tube that inhales the fire extinguishing agent is always directed toward the ground, so when it is installed in a container with a flat bottom, there is a gap between the edge of the flat bottom of the container installed upright and the lower part of the siphon tube. This occurs, making it impossible to completely inhale the fire extinguishing agent present at the edge of the flat bottom surface. Therefore, there is a problem in that residual amount of fire extinguishing agent is still generated at the edge of the bottom surface of the container even after the discharge of the fire extinguishing agent is completed.

Therefore, the present invention was devised to solve the above problems, and the technical problem to be solved by the present invention is to provide a gas fire extinguisher with a flat bottom so that it can be installed stably upright without auxiliary equipment such as a separate stand or stand. The siphon tube of the chemical storage container is formed with a two-stage joint capable of multi-stage bending so that the lower part of the siphon tube can easily reach vertically to the edge of the bottom of the gas-based fire extinguishing agent storage container, thereby allowing it to reach the edge of the bottom of the container. It facilitates the inhalation of remaining fire extinguishing agents to minimize the remaining amount discharged. This improves economics and fire extinguishing performance through efficient use of gas-based fire extinguishing agents, and saves auxiliary equipment, manpower, and time for installing storage containers. The goal is to provide a siphon tube for a gas-based fire extinguishing agent storage container that can reduce waste and improve price competitiveness.

It is coupled to the outlet and discharges the extinguishing agent, and the lower end is free, and an inlet is formed at the open end to inhale the extinguishing agent. The direction of the pipe is changed several times by the joint formed by bending the body, so the inlet is always at the edge of the bottom of the container. Between the gas-based fire extinguishing agent storage container, including a suction part that reaches perpendicular to the part and inhales the fire extinguishing agent, and a main body coupling part connected to the upper end of the suction part and coupling the suction part to the fire extinguishing agent discharge port at the top of the container body. It's a phone house.

According to the present invention, the siphon tube of the gas-based fire extinguishing agent storage container is formed with a flat bottom so that it can be installed stably and upright without auxiliary equipment such as a separate stand or pedestal, and is formed into a multi-stage bending structure to form a gas-based fire extinguishing agent storage container. By allowing the lower part of the siphon tube to easily reach the edge of the bottom of the container, it is possible to easily inhale the fire extinguishing agent remaining on the edge of the bottom of the container and minimize the remaining amount of gaseous fire extinguishing agent. It can improve economics and fire extinguishing performance through efficient use of , and provides the advantage of improving price competitiveness by reducing the waste of auxiliary equipment, manpower, and time for installing storage containers.

Figure 3 is a state diagram illustrating the installation state of the siphon tube of the gas-based fire extinguishing agent storage container according to the present invention, and Figure 4 is a diagram illustrating an excerpt of the siphon tube of Figure 3, showing the siphon tube 100 according to the present invention. As illustrated in FIGS. 3 and 4, it may be configured to include a suction part 110 and a body coupling part 120. The siphon tube 100 of the present invention can be implemented by applying to a gaseous fire extinguishing agent storage container using powder fire extinguishing agent, halon fire extinguishing agent, clean fire extinguishing agent, carbon dioxide fire extinguishing agent, etc. In particular, the bottom surface of the container (12) The central part (12a) of the container is located higher than the peripheral edge part (12b), so that the load of the fire extinguishing agent stored at the bottom of the container body 11 is distributed to the edge part 12b of the bottom surface 12 of the container, making it stable and independent. It is preferable to apply it to a storage container that can be installed.

The suction part 110 is disposed at the center of the interior along the longitudinal direction of the container body 11, and the upper end is coupled to the fire extinguishing agent discharge port 13 at the top of the container body 11 to discharge the fire extinguishing agent, and the lower end is free. An inlet 111 for inhaling a fire extinguishing agent is formed at the open end. This suction portion 110 is formed by first bending the body inclined at a first angle to the side of the container body 11, and secondarily bending the body first inclined at the first angle to the lower end of the container body again at a first angle. Equipped with a two-stage joint 112, the direction of the pipe is changed twice so that the suction port 111 at the lower part always reaches the edge 12b of the bottom surface 12 of the container perpendicularly. As a result, the suction port 111 at the lower end of the suction unit 110 is formed so as to always reach perpendicular to the edge portion 12b of the bottom surface 12 of the container to inhale the fire extinguishing agent. Here, the suction port 111 has a tapered inclined portion 111a formed on one side so that a portion of the cross section of the body forming the end is inclined to open toward the central portion 12a of the container bottom surface 12. It is configured to facilitate inhalation of the fire extinguishing agent from the edge portion (12b).

The two-stage joint portion 112 is formed at a position adjacent to the suction port 111 so that the suction port 111 can reach the edge portion 12b perpendicularly at a height close to the bottom surface 12 of the container, thereby preventing the container from discharging the fire extinguishing agent. It is easy to inhale the fire extinguishing agent from the edge portion 12b of the bottom surface 12 of the container located at the bottom of the main body 11. To this end, the two-stage joint portion 112 may be configured to include a first joint portion 112a, a second joint portion 112b, and a spaced portion 112c.

The first joint portion 112a is formed by first bending the body of the suction portion 110 adjacent to the suction port 111 at a first angle from the longitudinal center of the container body 11 to the side thereof to form a pipe of the suction port 110. Changes direction to be inclined at a first angle with respect to the longitudinal direction of the container body 11.

The second joint portion 112b connects the body of the suction portion 110, which is primarily bent at a first angle with respect to the longitudinal direction of the container body 11 by the first joint portion 112a, at the lower end of the first joint portion 112a. The lower end of the container body 11 is secondarily bent at a first angle to change the direction of the pipe of the suction part 110 to be parallel to the longitudinal direction of the container body 11.

The spacing portion 112c is located between the first joint portion 112a and the second joint portion 112b to space the second joint portion 112b at a certain distance from the lower end of the first joint portion 112a. Here, the length (L) of the spaced portion (112c) that separates the second joint portion (112b) from the lower end of the first joint portion (112a) is the inner diameter (D) of the container body and the spaced portion (112c) as illustrated in FIG. 3. With respect to the vertical height (H), it is formed to satisfy the conditions of Equation 1 below.

(Formula 1)

As a result, the spacing portion 112c allows the suction port 111 at the lower end of the suction portion 110 to be positioned as close as possible to the edge portion 12b on the bottom surface 12 of the storage container, so that when the fire extinguishing agent is discharged, the bottom surface ( 12) Even the fire extinguishing agent that accumulates in the concave groove of the edge 12b can be easily inhaled and discharged.

In this two-stage joint portion 112, the first joint portion 112a, the second joint portion 112b, and the spaced portion 112c are formed as a single body, thereby simplifying the manufacturing process of the siphon tube or the assembly process of the siphon tube in the storage container. Make it possible to do it.

The body coupling part 120 is connected to the upper end of the suction part 110 and couples the suction part 110 to the fire extinguishing agent discharge port 13 at the top of the container body 11, thereby discharging the container body 11 from the upper end of the siphon tube. The fire extinguishing agent is allowed to be released through the fire extinguishing agent discharge port 13 at the top.
