The invention discloses a prefabricated directly-buried thermal-insulation valve structure. The prefabricated directly-buried thermal-insulation valve structure comprises a valve main body, a flange disc and a heat-preservation prefabricated part, wherein a first semi-section module and a second semi-section module, which are of the same specification, are locked with each other to form the heat-preservation prefabricated part; a valve body accommodating cavity is arranged in the middle of the heat-preservation prefabricated part for preserving heat for the valve main body; the two ends of thevalve body accommodating cavity are equipped with pipeline heat-preservation sleeves with reduced diameters to cover the outer wall of a pipeline; the top end of the valve body accommodating cavity is in perpendicular conduction connection with a flange disc accommodating cavity for covering the flange disc to preserve heat; the top end of the flange disc accommodating cavity is connected with aswitch heat-preservation sleeve with a reduced diameter for preserving heat for an operation part of the valve; and the outer surface of the heat-preservation prefabricated part is coated with a layerof the metal housing. The prefabricated directly-buried thermal-insulation valve structure can guarantee the heat-preservation effect of the pipeline valve very well, provides guarantee for normal operation of an urban heating pipe network, and has a very good practical value.
Description
technical field [0001] The invention relates to a thermal insulation valve, in particular to a prefabricated directly buried thermal insulation valve structure. Background technique [0002] The urban heating pipe network is one of the city's infrastructures, which is closely related to people's life. With the expansion of the coverage area of the heating pipe network, it plays an important role as a valve for heating regulation. Valves are important equipment essential for the maintenance, transformation, development, and safe operation of heat supply, distribution, and storage systems of pipeline networks. However, the operation of the valve requires good maintenance. When the temperature is below zero degrees Celsius in winter, the water accumulated in the valve pipe will turn into ice, which will not only make the valve unusable, but also cause frostbite and damage to the valve. , so it is necessary to insulate the valve and its connecting parts. At present, the meas...
