Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation elbows, in particular to a thermal insulation external protection elbow. Background Art

[0002] With the increasing awareness of energy conservation and environmental protection, insulation materials are increasingly used in industrial and civil buildings. Especially in pipeline systems, in order to reduce heat loss and improve energy efficiency, it is often necessary to use insulation materials to wrap the pipes. As an important part of the pipeline system, the insulation effect of elbows directly affects the energy efficiency of the entire pipeline system.

[0003] Traditional insulated elbows are usually made of a whole piece of material. Although they have a certain insulation effect, they are inconvenient during installation, removal and maintenance. For example, due to the differences in the shape and size of the elbows, traditional one-piece insulated elbows are often difficult to adapt to elbows of different specifications and shapes, resulting in installation difficulties, and once installed, they are difficult to remove and maintain.

[0004] In order to solve the above problems, segmented or combined thermal insulation elbows have gradually attracted attention. However, the existing segmented thermal insulation elbows are provided with butt joint edges on both sides for butt jointing. When installed, the two half shells are buckled together and fixedly connected by screws at the butt joint edges. However, there are deficiencies in the above structural design and connection method. When the two are aligned, it is not easy to align the edges of the two shells due to the lack of corresponding positioning structures, which easily leads to misalignment and poor installation effect.

[0012] In the above solution, the inner side surface of the butt joint edge has a plurality of anti-slip protrusions.

[0013] The elbow of the embodiment of the present application realizes the precise positioning of the semicircular shell by the design of the positioning groove and the positioning protrusion, thereby improving the installation efficiency and accuracy.

[0022] Example 1: Figure 1-4 A thermal insulation outer protection elbow comprises a pair of semicircular shells 100, the pair of semicircular shells 100 are butt-jointed together to form a thermal insulation outer protection elbow as a whole, the middle portion of the semicircular shell 100 has a corrugated pipe section, and the two side edges of the semicircular shell 100 are formed with butt joint edges 101 along the length direction thereof, a positioning groove 111 is provided on one side of the butt joint edge 101, and a positioning protrusion 112 is provided on the other side of the butt joint edge 101;

[0023] When a pair of the semicircular shells 100 are butt-jointed together, the positioning protrusions 112 on the two mutually aligned butt-jointed edges 101 are embedded and matched with the positioning grooves 111 .

[0024] In this embodiment, the protective elbow is formed by a pair of semicircular shells 100 connected together, so as to facilitate installation and removal and meet the requirements of different bending angles. The semicircular shell 100 can be made of polymer material.

[0025] The middle part of the semicircular shell 100 is designed as a bellows section, which can enhance the flexibility of the elbow and adapt to any angle of the elbow, and can also effectively absorb the deformation of the pipeline caused by temperature changes and prevent damage caused by thermal expansion and contraction.

[0026] The two side edges of the semicircular shell 100 are formed with butt joint edges 101 along the length direction, which play a role of accurate butt joint during installation. In order to ensure the accuracy of butt joint, a positioning groove 111 is provided on the butt joint edge 101 on one side, and a matching positioning protrusion 112 is provided on the butt joint edge 101 on the other side.

[0027] Furthermore, the positioning protrusion 112 has guiding inclined surfaces 113 on both sides, and the positioning groove 111 has positioning inclined surfaces 114 matched with the guiding inclined surfaces 113 on both sides of the groove bottom.

[0028] Guide slopes 113 are added on both sides of the positioning protrusion 112. The guide slopes have a certain inclination angle, which is intended to guide the positioning protrusion to enter the positioning groove more smoothly. Positioning slopes 114 are designed on both sides of the bottom of the positioning groove 111. The angles of these positioning slopes match the angles of the guide slopes 113, ensuring that when the positioning protrusion enters the positioning groove, the two can fit tightly and form a stable positioning.

[0029] During the installation process, as the positioning protrusion penetrates into the positioning groove, the positioning bevel and the guide bevel cooperate with each other to gradually guide the positioning protrusion to the correct position. When the positioning protrusion is fully embedded in the positioning groove, the positioning bevel and the guide bevel on both sides will fit tightly to achieve precise locking.

[0030] Example 2: Figure 1 and 4 The two ends of the semicircular shell 100 are provided with bent edges 102, and notches 121 are provided between the left and right ends of the bent edges 102 and the butt edge 101, and the notches 121 are opened along the length direction of the butt edge 101. The bent edges 102 are provided at the two ends of the semicircular shell 100, and the main purpose is to further improve the fit between the semicircular shell and the installation pipe after installation.

[0031] In a possible implementation, the shape of the bent edge 102 can be designed to be an arc or a straight edge, and the specific shape is determined according to actual needs and the shape of the installation pipe.

[0032] An open groove 122 is provided inside the bending edge 102 to facilitate bending the bending edge 102 at the open groove 122. The main function of the open groove 122 is to serve as a guide line for bending, so that the bending edge can be bent along a predetermined line during bending, thereby ensuring the accuracy and consistency of the bending. During the bending process, force can be gradually applied along the open groove to smoothly bend the bending edge to a desired angle and shape.

[0033] Example 3: Figure 5 The inner side of the butt joint edge 101 is inclined and extends toward the cavity of the semicircular shell 100, and after the two semicircular shells 100 are butt jointed, a cavity 103 for accommodating a sealing gasket is formed. The inner side of the butt joint edge 101 is inclined and extends toward the cavity of the semicircular shell 100, and after the two semicircular shells are butt jointed, a cavity 103 for accommodating a sealing gasket can be formed.

[0034] The inclination angle needs to be determined according to the thickness and material of the gasket to ensure that the gasket can be tightly and evenly filled in the cavity to provide a good sealing effect.

[0035] The inner side of the butt joint edge 101 has a plurality of anti-skid protrusions. The inner side of the butt joint edge 101 is provided with a plurality of anti-skid protrusions, which may be round, square, diamond or other shapes, and the main purpose is to increase friction, and when a sealing gasket is placed in the cavity 103, the stability of the sealing gasket can be improved.

[0036] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
