Description

Technical Field

[0001] This utility model belongs to the field of explosion-proof device technology, and in particular relates to an explosion-proof safety device for high-pressure hoses. Background Technology

[0002] In many fields such as industrial production, engineering machinery, and petrochemicals, high-pressure hoses are key components for conveying high-pressure fluids (such as hydraulic oil, gas, and corrosive liquids). Their safe and stable operation is directly related to the normal operation of the entire system and the personal safety of operators. However, during long-term use, high-pressure hoses are easily susceptible to safety hazards such as rupture and detachment due to factors such as medium corrosion, pressure fluctuations, frequent bending, and aging and wear. Once such a situation occurs, the instantaneous ejection of high-pressure fluid may cause equipment damage, production interruption, or even personal injury or death. Therefore, the safety protection of high-pressure hoses is particularly important.

[0003] Currently, there are many types of explosion-proof safety devices for high-pressure hoses on the market, but they have certain limitations in terms of structural design and adaptability. Most devices use a fixed connection structure and can only be used with high-pressure hoses of a specific diameter. However, the orifice diameter of high-pressure hoses used in different industries and equipment varies greatly. This means that in practical applications, it is necessary to customize corresponding safety devices for hoses of different specifications. This not only increases the equipment procurement cost but also makes inventory management more complicated. At the same time, during the installation process, due to the strict matching requirements between the device and the hose specifications, operators must repeatedly confirm whether the dimensions of the high-pressure hose and the interface are consistent before installation. If the specifications are inconsistent, it is easy to cause the installation work to be interrupted and the project schedule to be delayed. In addition, during equipment maintenance, maintenance personnel need to carry various specifications of interface accessories to meet the replacement or repair needs of different hoses. This not only increases the workload of maintenance personnel but may also affect maintenance efficiency due to the omission of accessories. Therefore, an explosion-proof safety device for high-pressure hoses is proposed. Summary of the Invention

The internal threaded sleeve is rotated clockwise, and the external threaded tube moves axially by the action of the thread groove, which drives the push tube to move and squeeze the interlocking toothed tube, so that it is closed and cooperates with the support tube to clamp and fix the hose. This solves the problem that there are many types of explosion-proof safety devices for high-pressure hoses on the market, but they have certain limitations in terms of structural design and adaptability.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0034] Please see Figures 1-5 As shown, this utility model is a high-pressure hose explosion-proof safety device, including an explosion-proof device body 111, which is used to monitor the internal pressure of the hose in real time, and also includes:

[0035] The connecting mechanism 2 consists of two sets, which are respectively installed at the liquid inlet and liquid outlet of the explosion-proof device body 111. The two sets of connecting mechanisms 2 contain the same components. The connecting mechanism 2 on the right side includes a pressing assembly 21, which includes an internally threaded sleeve 211 for pushing and pressing. The internally threaded sleeve 211 is provided with a biting tooth tube 214 for biting the rubber tube.

[0036] The connecting mechanism 2 also includes:

[0037] Mounting component 22 abuts against the explosion-proof device body 111 and the extrusion component 21. Mounting component 22 is used to connect the extrusion component 21 to the explosion-proof device body 111.

[0038] The sealing component 23 is disposed inside the extrusion component 21 and the mounting component 22. The sealing component 23 is used to seal the gaps between the structural components.

[0039] The inner ring of the internally threaded sleeve 211 is provided with a push tube 212. The inner wall of the push tube 212 contacts the outer surface of the engagement toothed tube 214. The inner ring of the engagement toothed tube 214 is provided with a support tube 213. The outer ring of the support tube 213 contacts the inner wall of the engagement toothed tube 214. The right side of the inner wall of the internally threaded sleeve 211 is beveled, and the diameter of the right side of the internally threaded sleeve 211 is larger on the left and smaller on the right. The left side of the inner wall of the push tube 212 is convex. The high-pressure hose body 114 is inserted into the externally threaded tube 22. The inner threaded sleeve 211 is fitted over the support tube 213, positioning it between the support tube 213 and the meshing toothed tube 214. Rotating the inner threaded sleeve 211 clockwise causes it to move axially through the thread groove of the outer threaded tube 222, which in turn moves the push tube 212 to squeeze the meshing toothed tube 214, causing it to close and clamp the hose together with the support tube 213. This design is compatible with multiple hose specifications, eliminating the need for customization, facilitating quick installation and maintenance, and reducing downtime and accessory carrying issues caused by incompatible specifications.

[0040] Several barbs 215 are provided on the right side of the inner wall of the biting tooth tube 214, and the barbs 215 face the left side of the biting tooth tube 214. When the push tube 212 squeezes the biting tooth tube 214, the barbs 215 on its inner wall simultaneously bite the outer surface of the high-pressure hose body 114 and embed into the interior. The dual action strengthens the fixing effect, effectively prevents the hose from falling off and the risk of pressure loss caused by internal liquid leakage, and significantly improves the safety and reliability of the device.

[0041] Warning lights 112 are installed on the left and right sides of the top of the explosion-proof device body 111. A loudspeaker 113 is installed on the left and right sides of the explosion-proof device body 111. High-pressure hose bodies 114 are provided on the left and right sides of the explosion-proof device body 111. The two high-pressure hose bodies 114 are respectively connected to the external of the support tube 213. The liquid outlet and liquid inlet of the explosion-proof device body 111 are provided with internal thread grooves 115.

[0042] Mounting assembly 22 includes an externally threaded tube 222, the outer surface of which is threaded to the inner threaded groove 115, a hexagonal knob 221 is welded to the center of the outer surface of the externally threaded tube 222, the right side of the outer surface of the externally threaded tube 222 is threaded to the inner threaded sleeve 211, and the left side of the inner wall of the externally threaded tube 222 is welded to the left side of the support tube 213 and the engagement toothed tube 214.

[0043] The sealing assembly 23 includes a pressure ring 231. The outer ring of the pressure ring 231 is connected to the right side of the inner threaded sleeve 211. A sealing ring 232 is installed on the right side of the pressure ring 231. The outer ring of the sealing ring 232 contacts the inclined surface of the inner wall on the right side of the inner threaded sleeve 211. The side of the pressure ring 231 away from the sealing ring 232 is connected to the right side of the push tube 212.

[0044] A sealing ring 233 is installed on the outer surface of the push tube 212. The outer ring of the sealing ring 233 contacts the inner wall of the external threaded tube 222. A sealing ring 234 is provided on the left side of the sealing ring 233. The sealing ring 234 is installed on the left side of the hexagonal knob 221. The side of the sealing ring 234 away from the pressure ring 231 contacts the side of the explosion-proof device body 111.

[0045] A specific application of this embodiment is as follows: In use, the high-pressure hose body 114 is first connected to the inlet and outlet of the explosion-proof device body 111. Specifically, the internal threaded sleeve 211 is first fitted onto the outside of the high-pressure hose body 114, and the external threaded tube 222 is connected to the internal threaded groove 115. Then, the hexagonal knob 221 is turned clockwise to rotate the external threaded tube 222. During the rotation of the external threaded tube 222, it will be threadedly connected to the internal threaded groove 115, thereby realizing the installation connection between the external threaded tube 222 and the explosion-proof device body 111. At the same time, the external threaded tube 222 corresponds to the internal liquid pipeline of the explosion-proof device body 111. Also, on the side of the hexagonal knob 221 near the explosion-proof device body 111... A sealing ring 234 is provided to provide a certain seal between the external threaded tube 222 and the explosion-proof device body 111. Then, the high-pressure hose body 114 is inserted into the external threaded tube 222, and simultaneously fitted onto the support tube 213. At this point, the high-pressure hose body 114 is positioned between the support tube 213 and the meshing toothed tube 214. The operator then rotates the internal threaded sleeve 211 clockwise. During this rotation, the internal threaded sleeve 211 moves axially along the external threaded tube 222 due to the external thread groove. This movement of the internal threaded sleeve 211 drives the push tube 212 to move as well. The push tube 212 is positioned outside the meshing toothed tube 214. During the movement of the interlocking toothed tube 214, it is squeezed, causing the interlocking toothed tube 214 to retract under the force. During this retraction, the support tube 213, in conjunction with its supporting and limiting function, compresses and fixes the high-pressure hose body 114, thus achieving the installation and fixation of the high-pressure hose body 114. Furthermore, it can be used with high-pressure hose bodies 114 of various diameters for installation and connection, solving the problem of differences in the orifice diameter of high-pressure hose bodies 114 used in different industries. The unified multi-orifice adaptation design allows this explosion-proof safety device to be directly applied to various equipment without the need for separate customization for specific hoses, reducing the problem of device idleness due to hose specification mismatch, and eliminating the need for pre-installation reverse engineering. The compatibility between the high-pressure hose body 114 and the interface is reconfirmed to reduce installation interruptions caused by specification incompatibility. Especially in emergency repair scenarios, it can quickly complete device docking, shorten downtime, and maintenance personnel do not need to carry interface accessories of various specifications. They can complete the replacement of the high-pressure hose body 114 or device maintenance simply by adjusting the adaptation structure, improving the convenience of maintenance operations. At the same time, during the movement of the push tube 212, the sealing ring 233 will move together. At this time, the outer ring of the sealing ring 233 will contact the inner wall of the external threaded tube 222, realizing the sealing effect between the push tube 212 and the external threaded tube 222. After the push tube 212 is pushed by the internal threaded sleeve 211 and contacts the inner wall of the external threaded tube 222, a reaction force will be generated.At this time, the push tube 212 will push the pressure ring 231, causing the sealing ring 232 to move. The sealing ring 232, under the action of the inclined surface on the right side of the inner wall of the internal threaded sleeve 211, will retract and contact the outer surface of the high-pressure hose body 114, thus sealing the gap between the internal threaded sleeve 211 and the high-pressure hose body 114.

[0046] Meanwhile, when the push tube 212 squeezes the meshing tooth tube 214, multiple barbs 215 on the inner wall of the meshing tooth tube 214 will bite the outside of the high-pressure hose body 114. At the same time, multiple barbs 215 will embed into the inside of the high-pressure hose body 114. The action of multiple barbs 215 strengthens the fixation of the high-pressure hose body 114, reduces the possibility of the high-pressure hose body 114 falling off, and reduces the possibility of internal liquid leakage and pressure loss, thus reducing the occurrence of safety accidents. During the use of the explosion-proof device body 111, a pressure sensor, a central controller and an electromagnetic shut-off valve are installed inside the explosion-proof device body 111. When the pressure is abnormal, the electromagnetic shut-off valve cuts off the liquid flow to reduce the risk of explosion. At the same time, when the pressure sensor detects abnormal pressure, in addition to activating the warning light 112 to flash and the loudspeaker 113 to sound an alarm through the central controller, it also assists and reminds the staff to carry out maintenance.
