Description

Portable leakage detection heat preservation box of head and flange

Technical Field

The utility model relates to an adiabatic engineering field relates to a portable leak detection heat preservation box of head and flange particularly.

Background

In the technical field of heat preservation of end sockets and flanges, two conventional methods are available at present:

the first method comprises the following steps: in order to find out whether a medium at the end socket flange leaks or not in time, the end socket flange is not subjected to heat preservation and heat insulation treatment, the end socket flange is exposed in the environment, whether liquid on the sealing surface of the flange leaks or not is observed by naked eyes, and whether gas leaks or not is detected by a gas detector in the surrounding environment of the flange. Such an approach has the following disadvantages:

firstly, the exposed end socket flange has high temperature, so that the potential safety hazard of burning and scalding is easily caused, a large amount of heat is lost in the transmission process of a medium, the energy consumption is increased, energy is not saved, and the economic benefit of a using factory is influenced;

secondly, the exposed end socket flange can enable the heat preservation on the two sides to be in an open state, rainwater can enter the heat preservation layers of the equipment or the pipelines on the two sides in the weather of wind and rain, so that the heat conductivity coefficient of the heat preservation layers is gradually increased, and the heat preservation is invalid. And rainwater entering the heat-insulating layer can also corrode the surface of the equipment, so that the service life of the equipment is influenced.

The end socket flange exposed outside is unevenly heated, so that the thick and large flange plate can be deformed for a long time, and the leakage risk is increased; on the other hand, the bolts are far away from the pipeline and are in cold air, so that the bolts are cooled to cause large temperature difference between the flange and the bolts, and the leakage risk is increased.

If a plurality of end socket flanges are exposed in one area, when one device has gas leakage, the gas detector can only detect that the surrounding air has gas leakage, but cannot determine which device has gas leakage, so that the working efficiency is greatly reduced.

And the second method comprises the following steps: and a heat insulating layer and a simple non-detachable protective layer are added outside the end socket flange according to the traditional method. Such an approach has the following disadvantages:

the outer layer of the heat insulation structure is provided with a thick heat insulation material, so that liquid leakage or gas leakage is difficult to find, potential safety hazards of flash explosion and fire can be caused, and the safe operation of the device is influenced.

Secondly, after the heat insulation material is wound according to the traditional method, when gas or liquid leaks, the heat insulation layer is polluted in a large area and is not easy to wipe, the heat insulation layer needs to be replaced again during detection or maintenance, and the detection and maintenance cost is very high.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an energy-concerving and environment-protective portable leak testing heat preservation box is in order to improve the life of head and flange to solved traditional head flange and not kept warm, the heat waste is great, and safe risk coefficient is big, and energy consumption scheduling problem higher, adopt traditional heat preservation back head flange can not dismantle the detection, and traditional job site machining precision is not high, the low scheduling construction problems of machining efficiency.

In order to solve the technical problem, the purpose of the utility model is realized through following technical scheme:

the portable leakage detection heat preservation box of the end socket and the flange is of a detachable structure, is formed by mutually and fixedly connecting two symmetrical split parts through hasps, is sleeved outside the end socket and the flange and plays a role in wind prevention and water prevention; the split is provided with a plurality of maintenance windows which are fixedly connected with the split through maintenance window hinges, so that whether the seal head and the flange have liquid leakage or not and the specific leakage position can be observed by opening the maintenance windows under the conditions that the leakage detection heat preservation box is not disassembled and the machine is not stopped, and the liquid leakage can be timely treated once being found; a gas leakage detection hole is reserved on the access panel, so that whether the seal head and the flange have gas leakage or not and the specific leakage position can be detected, and the maintenance is convenient and timely.

A high-temperature-resistant impermeable split heat-insulation layer is fixedly arranged on the inner wall of the split, and a high-temperature-resistant impermeable inspection window heat-insulation layer reserved with a gas leakage detection hole is fixedly arranged on the inner wall of the inspection window; the access panel heat preservation is T type structure, and the subdivision heat preservation is its corresponding L type structure, and the inseparable dress of access panel heat preservation is in the subdivision heat preservation for the access panel can inlay the dress in the subdivision. The inspection window can ensure that the whole leakage detection heat preservation box has good heat preservation effect under the condition that the inspection window is not opened; the inspection window can guarantee simple and quick observation and detection under the state of opening alone to when convenient the detection, save the cost of maintenance, reduce the potential safety hazard of device operation in-process, guarantee the economic benefits of mill.

An access panel supporting rod is arranged in the access panel. When the access window is opened, the access window can be fixedly opened at a certain angle by supporting the support rod of the access window, so that observation and detection are facilitated; under the state that the access panel is not opened, the access panel bracing piece is packed up to the accessible and the access panel is closed, makes things convenient for leak testing heat preservation box's sealed.

A rain cover is arranged on the gas leakage detection hole and fixedly arranged on the access window.

The rain-proof cover is transparent rain-proof cover, makes for clear glass or other materials, can be when head and flange leak gas quick convenient detection leakage situation.

The beneficial effects of the utility model reside in that:

portable leak testing heat preservation box of head and flange adopt detachable structure, be convenient for transportation and installation, repeatedly usable is in order to practice thrift and examines cost of maintenance. The maintenance window and the detection hole reserved on the heat preservation box greatly facilitate the leakage detection of the medium and provide convenient conditions for timely maintenance of the leakage part; the requirement of the end socket flange on heat preservation can be met, the leakage condition can be easily found, and compared with the traditional method, the method has very high use value and economic value; the leakage detection of gas medium and liquid medium can be simultaneously satisfied, the requirement of pipeline heat preservation is fully considered, and the application range is very wide. The heat-insulating material with high-temperature resistance and permeability resistance is fixedly arranged in the heat-insulating box, can be prefabricated in a factory, does not need to occupy a production field on site, is high in mounting efficiency, and saves the mounting time.
