The fire valve 1 according to an embodiment of the present invention is generally used in a fire hydrant, and a glove valve, an angle valve, etc. may be used depending on the intended use. The present invention can be applied regardless of the type of fire valve. A valve with a large capacity may be connected to the inlet pipe by a flange, and a valve with a small capacity by a screw type.

The fire valve 1 according to an embodiment of the present invention is installed in a fire hydrant, and is connected to a fire water supply pipe in one direction and a fire hose 1 to a fire hose in the other direction.

The configuration of the fire-fighting valve (1) according to an embodiment of the present invention is a valve body (6); The display unit 5 exposed to the outside so that the operator can visually confirm, one side is connected to the display unit 5, the other side is coupled to the valve body 6, the display unit 5, the fire water pressure A first pressure gauge 100 having a connecting pipe 200 for transmitting; and

A second pressure gauge 300 installed on the connection pipe 200 and connected to the manager's terminal through a communication network to transmit pressure information to the terminal; may include.

The valve body 6 having the inlet 3 formed on one side may have a screw hole 2 penetrating to the outside. The first hydraulic system 5 may be one generally used in a hydraulic line, and may be coupled to the valve body 6 through the screw hole 2 .

Reference numeral 4 denotes a fastening part 4 to which a fire hose is connected. Here, the valve of the present invention will be applicable to other fire-fighting lines other than the purpose to which only a fire hose is connected.

According to an embodiment, the second pressure gauge 300 includes a case 310 exposed to the outside; The flexible part 400 which is disposed inside the case 310, one side and the other side are respectively connected on the connection pipe 200, and expands and contracts according to the fire water pressure transmitted through the connection pipe 200. ;

a pressure collecting part 600 installed between the case 310 and the flexible part 400 to sense a pressure value change by the expansion and contraction of the flexible part 400; and a communication module that receives the pressure information from the pressure collection unit 600 and transmits it to the terminal to the outside.

In the fire-fighting valve 1 according to the present invention, the inlet 3 may be connected to a fire-fighting water supply line, and the fastening unit 4 may be connected to a fire hose. When the operator turns the handle of the Sobang valve, the fire water moves from the inlet 3 to the fastening 4 and is discharged through the fire hose.

When the valve is closed, fire-fighting water pressure is generally formed in the valve body 6 of the fire-fighting valve. Accordingly, the fire water pressure is transmitted to the display unit 5 through the screw hole 2 and the connecting pipe 200 .

One of the features of the present invention lies in the configuration of the second pressure gauge 300 installed on the connection pipe 200 . The operator may check the fire-fighting water pressure by looking at the display of the display unit 5 of the first pressure gauge 100 normally.

However, it is inconvenient to go to the fire hydrant and check the fire water pressure every time. According to the present embodiment, in the configuration of the second pressure gauge 300, when the pressure in the valve body 6 falls below a predetermined pressure by the communication module, a signal is sent to an external manager terminal or management server. Accordingly, the manager or the management server controlling the firefighting facility can accurately grasp the condition of the fire hydrant in the place where the fire hydrant is distributed throughout the building.

That is, the operator may directly check the level of water pressure of each fire hydrant through the first pressure gauge 100 , and may comprehensively check the fire fighting system of the entire building in one place through the second pressure gauge 300 .

The connection pipe 200 may be formed of a metal pipe to withstand water pressure. According to an embodiment, in the second pressure gauge 300 , the case 310 may be coupled to the central portion of the connection pipe 200 , and may be formed in a cylindrical shape having a larger diameter than the connection pipe 200 .

The flexible portion 400 (Flexible Portion) may be formed of a flexible resin material. One end and the other end of the flexible part 400 are each connected to the connecting pipe 200 . Therefore, the fire water 500 flowing through the valve body 6 may pass through the flexible part 400 when moving on the connecting pipe 200 .

Since the fire water pressure of the fire water 500 is very strong, the impact applied to the pipe is large when the operator opens the fire valve, and the fire water 500 flowing with the strong fire water pressure can give an impact to the flexible part 400, not the metal material. have. Therefore, durability such as corrosion or damage occurs on the inner surface of the flexible part 400 in direct contact with the fire fighting water 500 may be a problem.

In order to solve the above problem, the flexible part 400 according to an embodiment of the present invention has an inner layer 10 that withstands the fire water pressure generated by the flow of fire water 500 therein, and the pressure sensor is installed and An outer layer 40 covering the outer periphery of the inner layer 10 may be provided.

The inner layer 10 of the flexible part 400 may have a strong durability enough to resist the flow of the firefighting water 500, and may have a smooth surface. The outer layer 40 of the flexible part 400 may have a configuration in which a plurality of pressure collecting cells are arranged while protecting the inner layer 10 . Since the outer layer 40 is a configuration in which a plurality of pressure collecting cells are installed, a seating groove or a holder in which the pressure collecting cells can be seated may be formed, and the rigidity is relatively weaker than that of the inner layer 10 due to a complex surface structure.

The flexible part 400 according to this embodiment has a double structure of the inner layer 10 and the outer layer 40, thereby maintaining durability with the inner layer 10 configuration, and forming the outer layer 40 with a material with good moldability. There is an advantage that the manufacturing process is simplified and the manufacturing time can be reduced.

However, the point that the flexible part 400 according to this embodiment has a double structure of the inner layer 10 and the outer layer 40 is that when the fire water pressure is strong, the inner layer 10 is pushed by the water pressure, and the inner layer 10 and the outer layer ( 40) may cause separation problems. Therefore, in order to solve this problem, the present invention adopts the structure of the reinforcing body 30 .

That is, specifically, the flexible portion 400 according to the present embodiment is formed by winding or weaving wire so as to have a gap between adjacent wire wires, and a small diameter portion having a first outer diameter. (small part), a large-diameter part having a second outer diameter larger than the first outer diameter, and a tapered part whose diameter is enlarged toward the front end side or the other end side between the small-diameter part and the large-diameter part. a reinforcing body 30 integrally formed to have;

an inner layer (10) covering the outer periphery of the small-diameter portion of the reinforcing body (30);

and an outer layer (40) covering the outer periphery of the inner layer (10),

At least the large-diameter portion of the reinforcing body 30 may have a structure in which the outer layer 40 is buried.

Hereinafter, an embodiment of the structure of the flexible part 400 having the double structure of the reinforcing body 30 and the inner layer 10 and the outer layer 40 according to the present invention will be described.

As shown in Figs. 2 and 3, the flexible portion 400 according to the present embodiment has a gap 25 between the adjacent element wires 20 in order from the inside in the radial direction. The wound reinforcing body (coil body) 30, the inner layer 10 covering the outer periphery of the reinforcing body (coil body) 30, and the outer layer 40 covering the outer periphery of the inner layer 10 ) has In addition, in FIG. 3, in order to help understanding, the state which peeled off part of the outer layer 40 and the inner layer 10 is shown.

The inner layer 10 is formed of resin (樹脂), and fire-fighting water 500 can flow therein. The resin material forming the inner layer 10 is not particularly limited, but polyamide, polyamide elastomer, polyester, polyurethane, polyethylene, or the like can be used.

In the inner layer 10 , a coil body 30 as a reinforcing body is provided. This coil body 30 is formed by winding the element wire 20 . Although stainless steel (SUS304) was used in 1st Embodiment as a material of the element wire 20 which comprises the coil body 30, it is not limited to this. For example, you may use not only metal materials, such as tungsten and a Ni-Ti alloy, but also resin materials, such as reinforced plastics (PEEK). In addition, the winding direction of the element wire 20 which comprises the coil body 30 may be a right direction toward the front-end|tip side, or a left direction may be sufficient as it.

An outer layer 40 made of resin is formed on the outer periphery of the inner layer 10 , and covers the inner layer 10 and the reinforcing body (coil body) 30 .

To one end and the other end (not shown in the drawing) of the above-described flexible portion 400, a coupling portion 70 made of a resin or a metal material is joined. The combination serves to couple the metal connection pipe 200 and the flexible part 400 .

As shown in FIG. 2 , the reinforcing body (coil body) 30 has a small-diameter portion 31 having a first outer diameter D1, and one end of the small-diameter portion 31 is larger than the first outer diameter D1. It is integrally formed to have a large-diameter portion 33 having a second outer diameter D2, and a tapered portion 32 whose diameter is enlarged toward one end between the small-diameter portion 31 and the large-diameter portion 33, and the reinforcing body (coil body) 30 floats from the inner layer 10 and is buried in the outer layer 40 at the large diameter portion 33 or at the tapered portion 32 and the large diameter portion 33 .

In the flexible portion 400 , the reinforcing body (coil body) 30 has an enlarged diameter from the small-diameter portion 31 toward the large-diameter portion 33 , and in the large-diameter portion 33 , or a tapered portion 32 and In the large diameter part 33, due to the anchor effect between the outer layer 40 and the wire 20 buried therein, the outer layer 40 by hydraulic shock when the fire extinguisher 500 moves inside the flexible part 400 ) is pulled in the axial direction (one end direction and the other end direction), it is possible to reduce the possibility that the outer layer 40 is peeled off from the inner layer (10).

According to an embodiment, the reinforcing body 30 may be formed of a material having high thermal conductivity, and may be composed of a heating element that generates heat by electrical connection. This configuration can prevent the flexible part 400 from curing when the temperature of the outside air is low by increasing the temperature of the flexible part 400, and it is possible to prevent the pressure sensor, which is an electronic device, from malfunctioning due to the low external temperature. .

According to an embodiment, the reinforcing body 30 may be formed of a Peltier element. In this case, the Peltier element is formed in a spiral, and the surface emitting cold air may be set to face the outer layer 40 , and the surface to radiate heat may be set to face the inner layer 10 .

Even if cold air is transmitted to the inside of the flexible part 400 through the inner layer 10, the temperature of the fire fighting water 500 does not change significantly. However, when the temperature of the external environment of the hydrant is lowered, the outside of the flexible part 400 is hardened and flexible This can fall. When the flexibility of the outer layer 40 of the flexible portion 400 opposite to the case 310 is reduced, the degree of expansion is not performed as expected, and the collected pressure value becomes inaccurate, and there is also a problem with the durability of the pressure sensor, which is an electronic device. becomes That is, the pressure value is changed according to the temperature of the outside air, the durability of the pressure sensor is weakened, and inaccurate pressure information may be collected.

In the case of a fire hydrant exposed to the outdoors by transferring heat to the outside of the flexible part 400 by the structure in which the reinforcement body 30 according to this embodiment is formed of a Peltier element, when the temperature of the external environment falls, the outer layer 40 It is possible to prevent the outer layer 40 from being cured by increasing the temperature.

On the other hand, when the fire-fighting water pressure inside the flexible part 400 is high, the flexible part 400 expands, and when the fire-fighting water pressure is low, the flexible part 400 may contract. The flexible part 400 may expand and contract and press the pressure collecting part 600 . The pressure collecting unit 600 may include, for example, a resistance sensor, and is electrically connected to the communication module. Accordingly, the resistance value changes according to the degree to which the pressure collecting unit 600 is pressurized, and pressure information can be transmitted to the communication module.

The case 310 is made of a metal material, and since the flexible part 400 is formed of a flexible resin material, as the flexible part 400 expands, the gap between the flexible part 400 and the case 310 is narrowed and the flexible part ( The pressure collecting unit 600 interposed between the 400 and the case 310 may be pressed.
