Description

Technical Field

[0001] The invention belongs to the technical field of fire hoses, and in particular relates to a fire hose that is resistant to burning and leakage and a manufacturing process thereof. Background Art

[0002] Firefighters will keep moving during the firefighting process to allow the water column to be sprayed to the right position, so the fire hose will move with it. If a particularly large fire or forest fire occurs, the fire hose will move a long distance. However, the ashes on the ground at the fire scene are sometimes mixed with sparks and the temperature is relatively high. In this case, the fire hose will be burned and scalded, affecting the progress of the firefighting. Now some manufacturers have made improvements by punching holes on the surface of the hose to artificially make the hose leak a little (leakage), but mechanical drilling will damage the internal structure of the hose, reduce its strength, and make some indicators of the hose fail to meet the standards. Therefore, it is necessary to develop a new fire hose to solve this technical problem. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a burn-proof and leakage-proof water hose and a manufacturing process thereof. The method is novel and the preparation is simple. On the basis of not destroying the original water hose structure, the water hose can be pressurized to seep water from the inside to the outside. In this way, the surface of the water hose is moist during firefighting and will not be easily scalded or burned by remaining sparks, thereby ensuring the normal use of the water hose.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A burn-proof and leakage-proof water hose comprises a water hose body and an attached needle ring, wherein the water hose body comprises an outer woven layer and an inner lining layer, and the attached needle ring comprises a cable tie and a water pipe, wherein the cable tie is arranged between the woven layer and the inner lining layer, and the water pipe is evenly and vertically arranged on the periphery of the cable tie, and the water pipe is in a hollow frustum shape, which is small inside and large outside, and the outlet of the water pipe is exposed outside and the upper edge is flush with the inner wall of the inner lining layer.

[0006] As an improvement of the present invention, the cable tie is made of hydrophilic material.

[0007] As an improvement of the present invention, in the length direction of the leakage water belt, a plurality of cable ties are arranged between the braided layer and the inner lining layer, and a plurality of water pipes are evenly and vertically arranged on the periphery of each cable tie.

[0008] As an improvement of the present invention, the diameter of the tail end of the water delivery pipe is greater than the width of the tie.

[0010] As an improvement of the present invention, the outer diameter of the water pipe outlet is less than 1 mm, and the outer diameter of the tail end is less than 3 mm.

[0011] As an improvement of the present invention, the braided layer is woven from polyester or nylon flame retardant material.

[0012] The manufacturing process of the anti-burning and leakage water belt described in the present invention comprises the following steps:

[0013] (1) Weaving the flame retardant silk material into a braided layer;

[0014] (2) Tie several cable ties to the outer layer of the braided layer, evenly and vertically set several water pipes around each cable tie. The height of the water pipes should be the same as the thickness of the inner lining layer, and insert a thumbtack at the outlet of the water pipes;

[0015] (3) The two ends of the braided layer are fixedly sealed and hot air at 60-70°C is passed through. The internal pressure is maintained at 0.6-0.8Mpa. Rubber liquid is sprayed on the surface of the rotating braided layer until the designed thickness is reached to form an inner lining layer. The temperature is maintained and the rotation is continued for 30-40 minutes. Then the two ends are opened until it cools naturally.

[0016] (4) Remove the leaking hose after step (3) and pull out the nails.

[0017] (5) Turn over the leaking water belt after step (4) so ​​that the woven layer is exposed outside and the lining layer is hidden inside.

[0027] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0028] like Figure 1 As shown, a burn-proof and leakage-proof water hose described in the present invention includes a water hose body 1 and an attached needle ring 4, wherein the water hose body includes an outer woven layer 2 and an inner lining layer 3, and the attached needle ring 4 includes a cable tie 5 and a water pipe 6, wherein the cable tie 5 is arranged between the woven layer 2 and the inner lining layer 3, and the water pipe 6 is evenly and vertically arranged on the periphery of the cable tie 5, and the water pipe 6 is in a hollow frustum shape, which is small inside and large outside, and the outlet of the water pipe 6 is exposed outside and the upper edge is flush with the inner wall of the inner lining layer 3.

[0029] The anti-burn and leakage water hose described in the present invention, without destroying the original water hose structure, is provided with a water pipe 6 in the inner lining layer so that a plurality of fine holes are formed on the surface of the inner lining layer. When putting out a fire, water is poured into the leaking water hose, and the internal pressure of the water hose begins to increase. The water will seep into the tie 5 and the braided layer 2 along the water pipe 6. Since the water pipe 6 is in the shape of a hollow truncated cone, which is small inside and large outside, once water enters, it will diffuse around and leak from the inside to the outside in a short time. In this way, the surface of the water hose will begin to be slightly moist, and it will be difficult to be burned, thereby protecting the water hose.

[0030] The outlet outer diameter of the water pipe 6 described in the present invention is less than 1mm, the tail end outer diameter is less than 3mm, the holes are very small but numerous, water will seep out under pressure but will not spray out, so the internal pressure of the water hose will not be reduced much, ensuring normal firefighting.

[0031] The cable tie 5 of the present invention is arranged between the braided layer 2 and the inner lining layer 3. The cable tie 5 is made of a hydrophilic material. The water pipe 6 is glued to the cable tie 5. The diameter of the tail end of the water pipe 6 is larger than the width of the cable tie. Figure 2 As shown, after water enters the water pipe 6, it will wet the cable tie 5 and the braided layer 2 on both sides of the cable tie, and then slowly diffuse outward. This structure expands the area of ​​water diffusion. Although it seeps slowly, the penetration rate is not slow, and the water hose can be quickly protected.

[0032] The braided layer 2 of the present invention is woven from polyester or nylon flame-retardant material, which has flame-retardant properties and can also prevent burning.

[0033] The manufacturing process of the anti-burning and leakage water belt described in the present invention comprises the following steps:

[0034] (1) weaving the flame retardant silk material into a braided layer 2;

[0035] (2) Tie a number of cable ties 5 to the outer layer of the braided layer 2, and evenly and vertically set a number of water pipes 6 on the periphery of each cable tie 5. The height of the water pipe 6 is the same as the thickness of the inner lining layer 3. Insert a thumbtack 7 at the outlet of the water pipe 6 (to prevent glue from entering the water pipe 6 during glue spraying and ensure that the internal channel of the water pipe 6 is unobstructed);

[0036] (3) The two ends of the braided layer 2 are fixedly sealed and hot air at 60-70°C is passed through. The internal pressure is maintained at 0.6-0.8Mpa. Rubber liquid is sprayed on the surface of the rotating braided layer until the designed thickness is reached to form the inner lining layer 3. The temperature is maintained and the rotation is continued for 30-40 minutes. Then the two ends are opened until it cools naturally;

[0037] (4) Remove the leaking hose after step (3) and pull out the nail 7.

[0038] (5) Turn over the leaking water belt after step (4) so ​​that the braided layer 2 is exposed outside and the lining layer 3 is hidden inside.

[0039] According to the manufacturing process of the present invention, in the length direction of the leaking water hose, a plurality of groups of tie ties 5 are arranged on the outer layer of the woven layer 2, and a plurality of water pipes 6 are evenly and vertically arranged on the periphery of each tie 5, so as to ensure that there are a plurality of fine holes inside the water hose after the processing is completed, and water can seep out. The leaking water hose is not made by hot pressing the finished rubber hose on the woven layer 2, but by spraying glue to form the inner lining layer 3, so that the inner lining layer 3 formed by spraying glue fixes the water pipe 6 in the inner lining layer 3, and the outlet of the water pipe 6 is exposed to the outside and the upper edge is flush with the inner wall of the inner lining layer 3, which will not affect the flow of water in the water hose, and can also allow water to enter the woven layer 2 under pressure, leak out water, and protect the water hose.

[0040] The water pipe 6 described in the present invention is an elastic rubber hollow tube with certain elasticity. The water hose will not be affected when bending or moving. Moreover, the water pipe 6 is made of rubber material and can be combined with the inner lining layer 3 when the rubber liquid is sprayed on the inner lining layer 3, so there is no possibility of falling off after a long time.

[0041] It should be noted that the above content merely illustrates the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications all fall within the protection scope of the claims of the present invention.
