specific Embodiment

[0057]In actual use, when the weather turns cold, the bimetal deformation sleeve is pressed by the cold deformation to connect the heating sleeve and the control switch to drive the heating sleeve and the electric heating block on the heating sleeve to connect with the heat transfer sleeve. When the heating sleeve and the heating sleeve When the electric heating block on the top is connected to the heat transfer sleeve, the set control switch opens the connected electric heating block under the pressure of the bimetal deformation sleeve, so that the electric heating block is energized and generates heat to transfer to the heating sleeve and the heat transfer sleeve, so that the heat transfer sleeve The thermal sleeve heats up rapidly, and transmits the temperature to the thermal sleeve, which transmits the temperature to the wellhead, so that the wellhead heats up rapidly, thereby improving the production efficiency; when the temperature of the wellhead rises to a certain temper...

Abstract

The invention discloses a heat preservation device for high-efficiency energy storage wellhead equipment, which comprises a heat conduction sleeve connected with the wellhead equipment, a heating device and a heat preservation device arranged on the heat conduction sleeve, and the heating device comprises a heat transfer sleeve connected with the heat conduction sleeve and a double A metal deformation sleeve, the heat transfer sleeve is provided with a deformable support column, the deformable support column is connected to the heating sleeve, the heating sleeve is connected to the heat transfer pad cover, the bimetal deformation sleeve is connected to the heat transfer sleeve and the heating The sleeve is connected, and a heat insulation groove is arranged between the heating sleeve and the heat transfer sleeve, and the heat insulation groove is connected with the bimetal deformation sleeve. The device of the present invention can automatically heat up when it is cold, and can automatically stop heating when the temperature reaches a certain height, and the heat insulation tank and insulation layer can effectively carry out long-term heat preservation and heat insulation to prevent heat loss, effectively Save electric energy and increase the performance of the device.

Description

technical field [0001] The invention relates to the field of wellhead heat preservation, in particular to a heat preservation device for high-efficiency energy storage wellhead equipment. Background technique [0002] In oil field production, wellhead insulation is an important task. The annual heat preservation work requires a lot of manpower and material resources. The heavy tasks cause super labor intensity to the employees of the production unit. A large number of glass cloth, felt, and paint are constantly removed, wrapped, and brushed to keep warm; the dust from glass cloth, felt, and the toxic substances in the paint have greatly harmed the health of the majority of workers, causing physical and mental damage to the workers. It is very unfavorable for cost control and HSE management, and increases cost input. [0003] Traditional wellhead insulation work is heavy and labor-intensive. For a long time, the wellhead insulation method has been to purchase a large numb...
