Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline thermal insulation, and particularly relates to a detachable thermal insulation cover capable of eliminating installation gaps. Background Art

[0002] With the progress of the times, energy conservation and environmental protection are becoming more and more important, and thermal insulation has also developed rapidly in recent years.

[0003] However, faced with pipes of various sizes, most conventional insulation sleeves have disadvantages such as complex design and high cost; due to the insulation and waterproof requirements of the insulation sleeves, most of them use complex structures for contact sealing on both sides, which makes production cumbersome and expensive; in terms of materials, conventional insulation sleeves generally directly use glass fiber felt, cotton felt, sponge and other materials as the main thermal insulation measures, and these materials have disadvantages such as weak thermal insulation performance, water absorption, flammability, and low self-strength, which may cause water absorption during use, resulting in rapid performance degradation and combustion when exposed to fire. Utility Model Content

[0004] The purpose of the utility model is to solve the defects and shortcomings in the prior art and to design a detachable insulation cover which is simple in structure, stable and reliable, convenient and effective, improves thermal insulation performance, saves costs and can eliminate installation gaps.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a detachable insulation cover capable of eliminating the installation gap, comprising an insulation cover body that is a planar structure in a normal state, a first fixing bar and a second fixing bar are respectively provided at the left and right ends of the insulation cover body, the insulation cover body is detachably connected together through the first fixing bar and the second fixing bar to form a hollow cylindrical shape that is adapted to the pipeline, waterproof strips are provided at the connection points at the left and right ends of the insulation cover body, and gap filling strips are also provided between the connection points at the left and right ends of the insulation cover body and the pipeline.

[0006] Preferably, the insulation sleeve body is made of a composite material, which includes a glass fiber blanket buffer layer, a mesoporous insulation felt layer and an aluminum foil reflective layer connected in sequence from the inside to the outside.

[0007] Preferably, a plurality of matching screw holes are distributed on the first fixing bar and the second fixing bar, and the first fixing bar and the second fixing bar are detachably connected by screws.

[0008] Preferably, the first fixing bar and the second fixing bar are both made of hard materials.

[0009] Preferably, the first fixing strip and the second fixing strip are respectively arranged on the upper surfaces of the left and right ends of the thermal insulation sleeve body.

[0010] Preferably, the waterproof strip is provided on the connecting surfaces at the left and right ends of the thermal insulation sleeve body, that is, between the first fixing strip and the second fixing strip after connection.

[0011] Preferably, the gap filling strip is arranged above the waterproof strip.

[0012] After adopting the above technical solution, the detachable insulation cover provided by the utility model that can eliminate the installation gap has the following beneficial effects:

[0013] (1) Since the present invention does not have a complicated connection structure, the insulation sleeve corresponding to the pipe size can be easily cut during the production process, thereby greatly optimizing the production cost; the design of the hard fixing strip can disperse the force acting on it as much as possible, thereby eliminating the gap at the connection when fixing, so that the insulation performance is not affected; the design of the detachable connection is achieved by screws, and since screws are the most commonly used fixing accessories, they are low in cost and easy to use.

[0014] (2) The outer layer of the insulation cover of the utility model is the place with the highest probability of contact with water and fire, so the main materials used are a waterproof and fireproof aluminum foil reflective layer and a mesoporous insulation felt layer. In addition, the aluminum foil reflective layer can also reflect radiant heat transfer and reduce heat transfer; and the mesoporous insulation felt has an extremely low thermal conductivity due to the nature of nano-mesoporous pores. At the same time, it is waterproof, high-temperature resistant and non-flammable, further improving the performance and applicability of the insulation cover body; the elasticity provided by the innermost glass fiber blanket buffer layer can reduce the existence of small gaps, ensuring that the insulation cover body fits on the pipe, thereby ensuring the insulation effect.
