Embodiment Construction

[0009] Such as figure 1 , 2 As shown, the electric heating belt is mainly composed of a heating wire 5 and a glass fiber layer 2; The electric heating belt is placed in the heat preservation and fireproof quilt. In addition, the outer layer of the electric heating belt is provided with a silica gel layer 6 , and the electric heating wire 5 is placed in the glass fiber layer 2 . Press the heating wire 5 in the electric heating belt figure 1 The trend shown in is coiled in the glass fiber layer 2, and the two ends of the heating wire 5 are connected to the electrodes of the power socket hole 4, and then connected to the variable frequency oscillating step-down power supply through the wire 3.

[0010] figure 2 As shown, the electric heating belt is placed in the thermal insulation and fireproof quilt, that is, the electric heating belt and the thermal insulation and fireproof quilt together constitute the thermal insulation heating blanket of the Y-shaped wellhead oil prod...

Abstract

The invention relates to a thermal insulation blanket, which is especially suitable for a low-voltage thermal insulation heating device of well control equipment. It belongs to the technical field of heat conduction. It includes an electric heating belt composed of electric heating wire, glass fiber layer, and silica gel layer, and a thermal insulation and fireproof quilt composed of an outer layer of aluminum foil, an inner layer of fireproof cloth, and a middle layer of thermal insulation cotton. The electric heating belt is placed in the insulation cotton layer in the middle of the insulation and fireproof quilt. In the present invention, the electric heating belt can be used independently under certain circumstances. The outer layer of the electric heating belt is provided with a silicone layer, which not only enhances the insulation of the electric heating wire, but also increases its softness and strength, and overcomes the limitation of the traditional metal or ceramic surface that is not easy to bend. At the same time, the thermal insulation performance of the electric heating belt is increased. The invention has the advantages of fire prevention, leakage prevention, short circuit prevention, high thermal efficiency and the like.

Description

technical field [0001] The invention relates to a thermal insulation blanket, in particular to a thermal insulation heating blanket of a wellhead oil production equipment which is suitable for a low-voltage thermal insulation heating device of well control equipment. It belongs to the technical field of heat conduction. Background technique [0002] At present, the well control equipment thermal insulation devices used in various drilling, sidetracking, and major workover construction sites all use electric heating cables with a voltage of 220V for thermal insulation. The shortcoming of low temperature and short service life, at the same time, the outer layer material of some electric heating belts is made of metal or ceramics, so it is not easy to bend, so it is not easy to wrap the Y-shaped wellhead equipment. Above-mentioned these defectives have become a great potential safety hazard of underground operation construction in winter. For this reason, we have specially de...
