Description

Technical Field

[0001] This utility model relates to steel wire pipes, and more particularly to a high-temperature and high-pressure resistant steel wire pipe assembly. Background Technology

[0002] Currently, Chinese patent CN220470869U discloses a steel wire brake hose, including a brake hose body; a rubber inner layer disposed inside the brake hose body; a steel wire layer disposed between the rubber inner layer and the brake hose body; two metal connectors disposed at both ends of the brake hose and fixedly installed on the brake hose body by connectors; and an installation component disposed on the connectors.

[0003] The aforementioned patent still has shortcomings. In the production process of steel wire brake hoses, due to the extrusion process of the rubber tube and the characteristics of the rubber material, it is usually impossible to guarantee that the diameter of the rubber tube is completely consistent. The metal joints are installed on both sides of the rubber tube. The connection and compatibility requirements between the metal joints and the rubber tube are high, and the error tolerance is low. When the size of the rubber tube cannot be guaranteed to be consistent, the sealing and stability between the metal joints and the rubber tube cannot be guaranteed, thus affecting the product quality. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a high-temperature and high-pressure resistant steel wire pipe assembly with a high fault tolerance rate for its metal joints.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a high-temperature and high-pressure resistant steel wire pipe assembly, including a water pipe body and joints disposed on both sides of the water pipe body. A water passage hole is opened in the water pipe. The joints include an installation pipe, an inner pressure pipe and an outer pressure pipe. The inner pressure pipe is disposed in the water passage hole and abuts against the inner wall of the water pipe body. The outer pressure pipe is sleeved on the outside of the water pipe body. An inclined top surface is also provided on the inner side of the outer pressure pipe. A pressure ring is provided on the installation pipe to drive the outer pressure pipe to press the water pipe body.

[0006] By employing the aforementioned technical means, and by setting up an inner pressure pipe and an outer pressure pipe, the joint clamps the water pipe body, increasing the joint's sealing performance. The pressure ring drives the inclined top surface to cooperate with the inner pressure pipe to press the water pipe body, thereby increasing the joint's fault tolerance and making it suitable for water pipe bodies of various sizes.

[0007] Preferably, the mounting tube has an external thread on its outer side, and the pressure ring includes a retaining ring and a screw ring. The retaining ring abuts against the external pressure tube, and the screw ring engages with the external thread of the mounting tube.

[0008] By using the above-mentioned technical means, the engagement between the rotating screw ring and the external thread of the installation pipe is achieved, thereby making the abutment ring press against the external pressure pipe during the rotation of the screw ring. The characteristics of the thread are used to press the water pipe body, increasing the sealing performance and preventing it from falling off.

[0009] Preferably, the outer surface of the inner pressure pipe is provided with a plurality of helical toothed rings, the diameter of which gradually increases from the outside to the inside. The inner side of the inner pressure pipe is also provided with a second water passage hole, and the installation pipe is provided with a third water passage hole.

[0010] By employing the aforementioned technical means, and by setting up a helical toothed ring with a gradually increasing diameter, the installation of the internal pressure pipe becomes easier. This also increases the friction between the internal pressure pipe and the water pipe body, further enhancing the joint's ability to prevent detachment.

[0011] Preferably, the mounting tube is further provided with an internal thread, and the tail of the internal pressure tube is threaded with the mounting tube.

[0012] Through the above technical means, the internal pressure pipe and the installation pipe are detachably connected, making it easy to replace internal pressure pipes of different sizes and adapting to water pipe bodies of various sizes.

[0013] Preferably, the installation pipe is also provided with a stop on the side near the water pipe body, and when the water pipe body is sleeved on the inner pressure pipe, the end face of the water pipe body abuts against the stop.

[0014] By using the above-mentioned technical means, by setting a stopper, the inner pressure pipe is placed against the stopper after it is installed in place, which restricts the position of the inner pressure pipe and prevents the inner pressure pipe from being installed too far inward, which would cause the outer pressure pipe and the inner pressure pipe to not be properly matched and tightened.

[0015] Preferably, the tail end of the internal pressure tube is further provided with a second inclined top surface, on which a sealing rubber ring is provided, and the inner side of the butt is further provided with a third inclined top surface, on which the second inclined top surface presses the sealing rubber ring onto the third inclined top surface.

[0016] By using the above-mentioned technical means, by setting up inclined top surface two and inclined top surface three, and by setting up sealing rubber rings, the sealing between the internal pressure pipe and the installation pipe is guaranteed, preventing water from leaking out from the threaded part between the internal pressure pipe and the installation pipe. At the same time, a certain reaction force is generated on the threaded connection to prevent the threads from loosening due to vibration.

[0017] Preferably, the water pipe body is composed of a rubber inner layer, a flame-retardant layer and a steel wire layer from the inside out.

[0018] Through the above-mentioned technical means, water pipes have the advantages of high temperature resistance, high pressure resistance and wear resistance. Attached Figure Description

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered.

[0025] A high-temperature and high-pressure resistant steel wire pipe assembly includes a water pipe body 1 and connectors 2 disposed on both sides of the water pipe body 1. A water passage hole 22 is opened inside the water pipe. The connector 2 includes an installation pipe 3, an inner pressure pipe 4, and an outer pressure pipe 5. The inner pressure pipe 4 is disposed inside the water passage hole 22 and abuts against the inner wall of the water pipe body 1. The outer pressure pipe 5 is sleeved on the outside of the water pipe body 1. An inclined top surface 6 is also provided on the inner side of the outer pressure pipe 5. A pressure ring 7 is provided on the installation pipe 3 to clamp the connector 2 to the water pipe body 1, thereby increasing the sealing performance of the connector 2. The pressure ring 7 drives the inclined top surface 6 to cooperate with the inner pressure pipe 4 to press the water pipe body 1, thereby making the connector 2 highly adaptable and flexible when assembling with the water pipe body 1, with good fault tolerance, and suitable for water pipe bodies 1 of various sizes.

[0026] The outer side of the mounting pipe 3 is provided with an external thread 8. The pressure ring 7 includes a retaining ring 9 and a screw ring 10. The outer side of the screw ring 10 is an external hexagon, which is convenient for screwing with a wrench. The retaining ring 9 abuts against the external pressure pipe 5. The screw ring 10 is engaged with the external thread of the mounting pipe 3. By rotating the screw ring 10 and engaging with the external thread 8 of the mounting pipe 3, the retaining ring 9 is pressed against the external pressure pipe 5 during the rotation of the screw ring 10. The characteristics of the thread are used to press the water pipe body 1, increasing the sealing and anti-detachment ability.

[0027] Several helical toothed rings 11 are also provided on the outer surface of the inner pressure pipe 4. The diameter of the helical toothed rings 11 gradually increases from the outside to the inside. A second water passage hole 12 is also provided on the inner side of the inner pressure pipe 4, and a third water passage hole 13 is provided inside the installation pipe 3. By setting helical toothed rings 11 and gradually increasing the diameter of the helical toothed rings 11, it is easier to install the inner pressure pipe 4. At the same time, the friction between the inner pressure pipe 4 and the water pipe body 1 is increased, further increasing the anti-detachment ability of the joint 2.

[0028] The mounting pipe 3 is also provided with an internal thread 14. The tail of the inner pressure pipe 4 is threaded with the mounting pipe 3, so that the inner pressure pipe 4 and the mounting pipe 3 are detachably connected, which makes it easy to replace the inner pressure pipe 4 of different sizes and adapt to water pipes of various sizes. The mounting pipe 3 is also provided with a butt 15 on the side near the water pipe body 1. When the water pipe body 1 is fitted on the inner pressure pipe 4, the end face of the water pipe body 1 abuts against the butt 15. The tail of the inner pressure pipe 4 is also provided with a second inclined top surface 16. A sealing rubber ring 18 is provided on the second inclined top surface 16. The inner side of the butt 15 is also provided with a third inclined top surface 17. The second inclined top surface 16 presses the sealing rubber ring 18 on the third inclined top surface 17.

[0029] During installation, first screw the inner pressure pipe 4 into the installation pipe 3, then put the inner pressure pipe 4 into the water pipe body 1, then put the outer pressure pipe 5 on the outside of the installation pipe 3 and pre-tighten it, then screw in the pressure ring 7 and completely press the outer pressure pipe 5 onto the water pipe body 1, causing the water pipe body to deform.

[0030] The water pipe body 1 is composed of a rubber inner layer 19, a flame retardant layer 20 and a steel wire layer 21 from the inside out. The rubber inner layer 19 is made of silicone rubber, which has excellent high temperature resistance. The flame retardant layer 20 is made of neoprene rubber, which has good flame retardancy and good adhesion to the steel wire layer 21. The steel wire layer 21 is braided and set on the outside of the flame retardant layer 20 to play a protective role.

[0031] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
