Description

Flexible hose include a check valve

  The present invention mainly relates to a flexible pipe for piping a fire extinguishing facility such as a high-pressure gas container in a fire extinguishing system using a gas (Halon 1301, carbon dioxide, a clean extinguishing agent, etc.). It is configured integrally.

  In general, the gas (Halon 1301, carbon dioxide, clean extinguishing agent, etc.) extinguishing equipment is to quickly extinguish the fire by injecting the extinguishing agent from the high-pressure gas container through a fire extinguishing means such as an injection head when a fire occurs, In such a gas fire extinguishing facility, a piping work is performed to supply gas from a high pressure gas container to an injection head for fire extinguishing, and a flexible hose that is easily deformable for ease of operation is widely used.

  In addition, the gas fire extinguishing facility is installed by connecting a plurality of high-pressure gas vessels filled with high-pressure gas, and an appropriate number of high-pressure gas containers are selected according to the small screen area in which the extinguishing gas is supplied in case of fire. The gas is configured to be supplied.

  Therefore, the one-way valve is installed in each high-pressure gas container, and the flexible pipe is connected thereto to connect the high-pressure gas containers to each other.

 For the gas fire extinguishing facility, as previously described above, the one-way valve is separately connected and the flexible pipe is connected to the gas pipe, and thus the workability is not easy and the equipment cost is expensive.

  Looking at the above problem in detail as follows.

  In order to construct a gas fire extinguishing facility, the work of one-way valve was piped and the flexible pipe was connected to it again, which made workability cumbersome and inefficient.

  That is, since the one-way valve and the flexible pipe body must be separately assembled, a number of processes are required for their piping work, and the one-way valve and the flexible pipe body are separately prepared, so that the inefficiency and cost of the work are required at high cost.

 In addition, by connecting the one-way valve and the flexible pipe separately, an airtight structure is required between the high-pressure gas container and the one-way valve and the one-way valve and the flexible pipe, which makes the workability difficult and cumbersome, as well as the work defect. It had many problems, such as high and poor stability of the whole installation.

  Therefore, in the present invention, the one-way valve and the flexible pipe body are manufactured in one structure, that is, one body, so that the flexible pipe body has the structure of the one-way valve. By omitting, it is intended that these processes are performed in one operation connecting flexible bodies, thereby providing convenience and efficiency of work, and pursuing various economic benefits such as cost reduction and stability of fire extinguishing equipment. I would like to.

 1 is a configuration diagram of a part of a flexible tube to which one embodiment of the present invention is applied, FIG. 2 is a cross-sectional view of the main portion of the present invention, FIG. 3 is a cross-sectional view of the working state of the present invention, and FIG.

  The present invention is characterized in that the one-way valve is integrally formed on the flexible pipe 1, which is a flexible pipe, and the configuration of the present invention will be described below in detail.

  The flexible tube 1 is formed by forming a flexible tube by forming a braid 1b outside the flexible flexible tube 1a.

 Opening and closing of the flexible pipe body (1) by integrally forming a nut pipe (2) having a coupling band (2a) formed at the end of the flexible pipe body (1) and the flow of fluid is interrupted by the valve body (4) inside the nut pipe (2) Ring 3 (hereinafter referred to as stainless ring) is built in.

 The stainless ring 3 is built-in and coupled between the nut pipe 2 and the flexible pipe body 1 connected by the coupling band 2a as shown in the example, and the stainless ring 3 has a valve body 4. ) Is combined in a flow state to perform the function as a one-way valve.

  The adapter 7 is coupled to the nut tube 2 side fastening portion 8, and a guide 5 for guiding the valve body 4 to the inside thereof is coupled.

  The guide 5 is fixed to the inside of the nut pipe (2) by the snap ring 6, the guide (5) performs the opening and closing function between the stainless ring (3) in the nut pipe (2) It is combined with a predetermined clearance space therefor.

  Guide hole 5 is formed in the center of the guide hole 51 as shown in Figure 4, the guide rod 41 of the valve body 4 is coupled to slide movement, the inner peripheral surface of the nut pipe (2) to allow fluid to pass through And a circulation space portion 52 forming a space therewith.

  Of course, the guide 5 may be configured in a variety of shapes, such as the distribution space 52.

  On the other hand, the valve body 4 is formed with a guide rod 41 on one side is slide coupled to the guide hole 51 of the guide 5 is made to move in the left and right direction, on the opposite side to the stainless ring (3) side The head part 42 is formed in close contact and separation, and the head part 42 is tightly coupled to the stainless ring 3 side by the spring 53 elastically coupled to the guide hole 51 side of the guide 5. And this state is maintained.

 The head part 42 of the valve body 4 forms a non-metallic packing material 43 such as a rubber mainly on the outside to increase adhesion to the metal stainless ring 3 to ensure excellent airtightness. It may be desirable to, and the stainless ring 43 is also configured to match the shape of the head portion 42 to the head portion 42 is in close contact with the contact area between the head portion 42 and the stainless ring (3) and It would be desirable to increase the adhesion to maintain strong airtightness.

  Then, the other end of the flexible pipe (1) formed with the valve body 4 to control the fluid in one direction is coupled to the socket (9) for piping work with a high-pressure gas container.

  The socket (9) is coupled to the nipple (10) connected to the flexible pipe (1) end integrally coupled to one side as a coupling band (10a), the gasket (11) between the socket (9) and the nipple (10) It is provided.

  In the present invention configured as described above, since the one-way valve is integrally formed on the flexible pipe body 1, the one-way valve must be assembled separately for the gas fire extinguishing facility and the flexible pipe body 1 must be connected again. The efficiency is reduced, and the compact structure is designed to simplify the installation process, reduce the manufacturing cost, and improve the stability of the facility with more airtightness.

  According to the present invention, since the one-way valve is integrally provided in the flexible pipe body 1, the one-way valve is assembled and installed as before, and the single pipe connecting the flexible pipe body 1 without the work of connecting the flexible pipe body 1 again is required. Many existing tasks can be performed as tasks, increasing the efficiency and efficiency of the task.

  In addition, the flexible pipe body (1) has a role of performing the one-way valve function directly, so that the existing airtight structure between the flexible pipe body (1) and the one-way valve should be provided, and the anxiety and concern due to defects in the assembly work therebetween. It is possible to solve, and the one-way valve function to control the flow of the fluid in the flexible pipe 1 in one way is made to ensure a very stable and excellent operability.

 That is, since the valve body 4 for controlling the fluid in one direction is embedded in the flexible pipe body 1 and the nut pipe 2 at one end, the valve body 4 maintains the airtightness to the connection portion between the one-way valve and the flexible pipe body 1 as before. There is no problem with this.

  In addition, the valve body 4 is slide guided to the guide hole 51 of the guide port 5, so that one end of the head part 42 performs the intermittent function while opening and closing the stainless ring 3 so that the intermittent fluid is flexible. In addition to smooth, the head portion 42 is formed of a non-metallic packing material 43 such as rubber to stably control the fluid with an excellent sealing force that is closely adhered to the metal stainless ring 3.

  The valve body 4 is opened while the fluid enters the head portion 42 and pushes the head portion 42 at the pressure to compress the spring 53 to open the valve space portion 52 of the guide 5. The fluid flows through the air, and when the fluid is no pressure, the fluid flow is controlled by closing the head part 42 of the valve body 4 close to the stainless ring 3 by the elastic force of the spring 53. It will be cracked down in one direction.

  As described above, the present invention eliminates the hassle and assembly process of the existing work that requires the one-way valve and the flexible pipe body 1 to be separately designed, manufactured, and plumbed by being configured integrally with the flexible pipe body 1. By doing so, you can increase the convenience and efficiency of your work, and achieve economic benefits that can greatly reduce your costs.

  The piping work of the flexible pipe (1) and the one-way valve, and thus there is no need for an airtight structure between them, which makes it possible to construct a fire extinguishing system more stably and compactly. Also, it can be expected to be widely used for the purpose of equivalent use and function.
