Description
Technical field
The utility model relates to the syndeton of the removable accompanying-heat cable of a kind of muff, belong to detachable heat-insulating cover technical field.
Background technology
Pipe conveying fluid is in order to be incubated, general needs are at the coated heat-insulation layer in the outside of pipeline and form muff, for increasing heat insulation effect, reduce the thermal loss of flow media in pipeline, at the outer only coated muff of pipeline not enough, usually also between heat-insulation layer, accompanying-heat cable is placed, due to muff local because the reasons such as fluid media (medium) leakage need field-strip, owing to being embedded with continuous print accompanying-heat cable in muff, once need the muff at local overhauling field-strip position, the normal power-up of continuous accompanying-heat cable certainly will be affected, at this time for the sake of security, often by the power-off of whole piece accompanying-heat cable, cause the larger thermal loss of fluids within pipes medium.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of structure simple, easy to install and use, be convenient to local overhauling maintenance, and the syndeton of the removable accompanying-heat cable of muff that other accompanying-heat cable normally works can not be affected when partial disassembly's muff.
The purpose of this utility model has been come by following technical solution, the syndeton of the removable accompanying-heat cable of a kind of muff, described muff is adjacent sliceable, be adjacent to the heat insulating block composition be arranged on pipeline, described heat insulating block is made up of the lagging casing of built-in heat-insulation layer and outsourcing, the accompanying-heat cable from a side to another side is surrounded with in heat-insulation layer, and a side end of described accompanying-heat cable is connected to the control device of peripheral hardware and connects external power by this control device, described accompanying-heat cable is connected by accompanying-heat cable connectivity port at the end that connects of two pieces of heat insulating blocks, described connectivity port picks out the connection cable that connects next section of accompanying-heat cable, and a hand switch is serially connected with on described connection cable.
Described heat-insulation layer is made up of at least one in composition silicate felt, glass fibre, and the hand switch of described connection cable and serial connection is all embedded in the outside heat-insulation layer near lagging casing; Described accompanying-heat cable is extruded by cable core and two parallel bus, additional insulating barrier, metal screen layer and anticorrosion restrictive coating are formed.
Described connection cable is that ordinary copper wire outer wrap insulating barrier, metal screen layer and anticorrosion restrictive coating are formed; Be equipped with a heat sensor between on the outer wall that described heat-insulation layer is close to pipeline, this heat sensor connects and the control device formed primarily of thermal switch; Described control device is serially connected in the power circuit of accompanying-heat cable by potential device external power supply.
It is simple that the utility model has structure, easy to install and use, is convenient to local overhauling maintenance, and can not affects the features such as other accompanying-heat cable normally works when partial disassembly's muff.
