Quickly-opened detachable heat-preserving box

Abstract

The invention relates to a quickly-opened detachable heat-preserving box which is of a split symmetric structure, wherein the front portion and the rear portion of the structure are buckled. The quickly-opened detachable heat-preserving box is characterized by comprising a protective layer (1), a heat isolating layer (2) and a reflective layer (3), wherein the split symmetric structure is fastened through quickly-opened locking buckles (7), and the butt joint face of the split symmetric structure is fixedly provided with a sealing supporting plate (4). The quickly-opened detachable heat-preserving box can be widely used for heat preservation of pipelines, valves, flanges, heat exchangers and other special equipment in the fluid storing and transporting processes.

Description

technical field [0001] The invention relates to a heat preservation device, in particular to a quick-opening detachable heat preservation box used for pipelines, valves, flanges, heat exchangers and other special-shaped equipment in the process of fluid storage and transportation. Background technique [0002] In the production process of oil and gas exploration, petroleum processing, chemical industry, pharmaceutical, power plant and other industries, the process of fluid storage and transportation is mostly accompanied by heat and cold loss. The insulation of pipes, valves, flanges, heat exchangers and other special-shaped equipment It becomes the key to energy saving and consumption reduction. The traditional method of heat preservation is to wrap the inside with thermal insulation material, wrap the outside with glass cloth and then paint. This method has an ugly appearance, and the glass cloth has a short service life and needs to be replaced frequently. In recent year...

Problems solved by technology

The traditional method of heat preservation is to wrap the inside with thermal insulation material, wrap the outside with glass cloth and then paint. This method has an ugly appearance, and the glass cloth has a short service life and needs to be replaced frequently

In recent years, some units have begun to change the shell into metal materials such as galvanized iron plate or thin aluminum plate, which prolongs the service life and increases the beauty of the thermal insulation appearance, but there are still some problems. Low strength, easily deformed when stepped on, especially valves, flanges and other parts that often need maintenance, repair or replacement, as long as they are opened, they cannot be restored and must be reprocessed, which not only causes waste, but also affects the normal production and operation of the device

[0003] CN200910024563.3 discloses a thermal insulation box of high-temperature-resistant soft outsourcing material. Although it solves the problem of quick disassembly and assembly, the product has a bloated appearance, poor aesthetics, and cannot withstand external forces. The interface connection uses nylon buckles, which are complicated to connect and low in strength

CN201110061206.1 discloses a valve insulation cover whose central body is a rigid coating, which ensures the close connection between the soft insulation layer in the cavity and the valve, but the valve insulation cover and the top handwheel are still soft structures. The zipper structure at the end and the top ensures quick opening performance, but the insulation box as a whole cannot bear pressure, the zipper seal is easily damaged, and the service life is short

CN200620027399 provides a kind of insulation box with up and down asymmetry, although there is a wire mesh between the insulation layer and the protective layer, the wire mesh is outside the insulation layer, so that the insulation layer cannot be tightly combined with the protective layer

What CN200920099616 and CN201220140361 provide is a kind of upper and lower asymmetric FRP insulation box shell structure. Large-scale valve insulation boxes often require dozens of screws, and disassembly and assembly are very complicated, time-consuming and laborious; at the same time, the glass fiber reinforced plastic material used in the technical solution has low flame retardancy, and its use in the petrochemical field is subject to certain restrictions

[0004] The common disadvantages in the prior art are: the outer protective layer is not an integral rigid structure, and its ability to withstand external forces is poor, and it is easy to crack or deform when it is pressed or stepped on; the insulation layer and the protective layer are not tightly combined, and it is easy to disassemble. Falling off; the insulation layer either directly contacts the valve or wraps it with glass cloth and then contacts the valve, resulting in heat conduction and reducing the heat insulation effect; the insulation layer is made of aluminum silicate, aluminum magnesium silicate, composite silicate, glass wool, Rock wool and other soft insulation materials, during the production and use process, the powder of the above materials is easy to float on the body or be inhaled into the lungs, which will seriously affect the operators
