Description

Technical Field

[0001] This utility model belongs to the field of hose technology, and in particular relates to a new type of heat-resistant steam hose. Background Technology

[0002] Steam hoses, also known as steam flexible hoses, are used for cooling water in refrigeration equipment, hot and cold water in engines, and hot water and saturated steam in food processing, especially dairy plants. They are resistant to dilute (low concentration) acids and alkalis. Like ordinary industrial hoses, steam hoses consist of an inner rubber layer, an outer rubber layer, and a middle layer. The inner and outer rubber layers are commonly made of EPDM material, which has excellent heat resistance, steam resistance, ozone and ultraviolet radiation resistance, and chemical resistance. The outer rubber layer is wrapped with tape, and the middle layer is usually braided or braided steel wire to enhance the hose's pressure resistance.

[0003] A novel steam hose, as described in application number 202321223426.4, includes a hose body and a connector. The hose body comprises an inner rubber layer, an intermediate layer fixedly wrapped around the surface of the inner rubber layer, and an outer rubber layer fixedly wrapped around the surface of the intermediate layer. A flange is fixedly connected to one end of the connector. An annular slot for inserting the hose body end is provided on the side of the connector away from the flange. The width of the annular slot is greater than the thickness of the hose body. With the hose body and connector, the hose body end can be inserted into the annular slot of the connector. The inner wall of the annular slot is designed with a slope, causing the hose body end to expand and be compressed within the annular slot, thus ensuring a tight seal between the hose body and the connector. The hose body end can then be fixed inside the annular slot using an internal hex bolt. This steam hose connector structure is simpler, and the assembly and connection method with the hose body is quicker and more convenient.

[0004] Existing steam hoses are prone to deformation due to the rubber material. As the usage time increases, they may not spring back after deformation. Additionally, leaks may occur at the hose connections, thus affecting the performance. Utility Model Content

[0005] This invention provides a novel heat-resistant steam hose designed to solve existing problems of deformation and leakage.

[0006] This utility model is implemented as follows: a novel heat-resistant steam hose includes a hose body, a connector fixed to one end of the hose body, an installation head provided at one end of the connector, an inner ring fixed inside the installation head near the hose body, and an outer ring fixed outside the installation head near the hose body. The outer surface of the inner ring is in contact with the inner surface of the hose body, and the inner surface of the outer ring is in contact with the outer surface of the hose body.

[0007] The connector is provided with a fixing mechanism on the side near the mounting head to reinforce the connection between the connector and the mounting head.

[0008] Preferably, the fixing mechanism includes a fixing ring, which is sleeved on the outside of the connector near the mounting head. One end of the fixing ring is fixed with an adjusting half-ring, which is embedded inside the fixing ring. This design allows the fixing ring to compress and reinforce the connection, preventing leakage at the connection point.

[0009] Preferably, an adjusting plate is fixed to one end of both the fixed ring and the adjusting half-ring, and an adjusting bolt is internally threaded onto the adjusting plate. The diameter of the combined fixed ring and adjusting half-ring can be adjusted by the action of the adjusting bolt.

[0010] Preferably, the fixed ring and the adjusting half-ring form a relatively movable structure through adjusting plates and adjusting bolts. The connection between the connector and the mounting head can be strengthened by adjusting the radius of the combined fixed ring and adjusting half-ring.

[0011] Preferably, the hose body includes an inner protective layer, a first heat-resistant layer outside the inner protective layer, a reinforcing layer outside the first heat-resistant layer, a second heat-resistant layer outside the reinforcing layer, and an outer protective layer outside the second heat-resistant layer. Using hoses made of materials with different properties can enhance the performance of the hose.

[0012] Preferably, the reinforcing layer includes reinforcing lines and leveling adhesive, with the reinforcing lines distributed alternately. The reinforcing lines can shape the hose.

[0013] Preferably, the inner protective layer, the first heat-resistant layer, the reinforcing layer, the second heat-resistant layer, and the outer protective layer are fixedly connected to each other. This allows the first and second heat-resistant layers to work together to enhance the heat resistance.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages:

[0015] This utility model, through the setting of the mounting head, can seal the connection point through the inner and outer rings when the hose body is connected and combined with other devices to prevent leakage. At the same time, the fixing ring can make the connection between the connector and the mounting head tighter to prevent detachment. Furthermore, the first and second heat-resistant layers enhance the heat resistance of the hose, and the reinforcing layer can shape the hose to prevent deformation during use.

Detailed Implementation

[0022] The following will be combined with the appendix Figures 1 to 5 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model provides a novel heat-resistant steam hose through improvements, such as... Figures 1-5 As shown, the device includes a hose body 1, a connector 2 fixed to one end of the hose body 1, an installation head 3 provided at one end of the connector 2, an inner ring 4 fixed inside the installation head 3 near the hose body 1, and an outer ring 5 fixed outside the installation head 3 near the hose body 1. The outer surface of the inner ring 4 is in contact with the inner surface of the hose body 1, and the inner surface of the outer ring 5 is in contact with the outer surface of the hose body 1. A fixing mechanism for reinforcing the connection between the connector 2 and the installation head 3 is provided outside the connector 2 near the installation head 3.

[0024] In this embodiment, the hose body 1 and the connector 2 form an integrated structure. When the connector 2 is installed with the mounting head 3, the connector 2 is embedded in the position between the inner ring 4 and the outer ring 5. At the same time, the outer surface of the inner ring 4 is in contact with the inner surface of the hose body 1, and the inner surface of the outer ring 5 is in contact with the outer surface of the hose body 1. Therefore, leakage at the connection can be avoided.

[0025] In the previous implementation scheme, the connection is prone to loosening over time. The specific steps are as follows:

[0026] like Figure 2 and Figure 3 As shown, the fixing mechanism includes a fixing ring 6, which is sleeved on the outside of the connector 2 near the mounting head 3. An adjusting half-ring 7 is fixed to one end of the fixing ring 6, and the adjusting half-ring 7 is embedded inside the fixing ring 6. Adjusting plates 8 are fixed to one end of both the fixing ring 6 and the adjusting half-ring 7, and adjusting bolts 9 are threaded onto the adjusting plates 8. The fixing ring 6 and the adjusting half-ring 7 form a relative movable structure through the adjusting plates 8 and the adjusting bolts 9.

[0027] In this embodiment: After the connection between connector 2 and mounting head 3 is completed, the fixing ring 6 is sleeved on the outside of connector 2. By rotating the adjusting bolt 9, the distance between the adjusting pieces 8 is reduced. Through the action of the adjusting pieces 8, the adjusting half ring 7 can be partially inserted into the interior of the fixing ring 6, thereby reducing the diameter of the combination of fixing ring 6 and adjusting half ring 7, thus making the connection between connector 2 and mounting head 3 tighter.

[0028] In the previous implementation plan, the hose is prone to deformation over time. The specific operation is as follows:

[0029] like Figure 4 and Figure 5 As shown, the hose body 1 includes an inner protective layer 10, a first heat-resistant layer 11 outside the inner protective layer 10, a reinforcing layer 12 outside the first heat-resistant layer 11, a second heat-resistant layer 13 outside the reinforcing layer 12, and an outer protective layer 14 outside the second heat-resistant layer 13. The reinforcing layer 12 includes reinforcing lines 15 and leveling adhesive 16, with the reinforcing lines 15 interleaved. The inner protective layer 10, the first heat-resistant layer 11, the reinforcing layer 12, the second heat-resistant layer 13, and the outer protective layer 14 are fixedly connected to each other.

[0030] In this embodiment: the heat resistance of the hose is increased by the combined action of the first heat-resistant layer 11 and the second heat-resistant layer 13. At the same time, the hose can be protected from the inside and outside by the combined action of the inner protective layer 10 and the outer protective layer 14, thereby avoiding damage. The reinforcement layer 12 can be used to shape the hose and prevent deformation.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
