Abstract

The invention relates to a compensator special for a heat preserving pipeline of a greenhouse. The compensator special for the heat preserving pipeline of the greenhouse comprise an outflow end joint pipe, a sleeve, a packing filling opening, a sealing cover, an inner retaining ring, packing, an outer retaining ring, an adjusting bolt and an inflow end joint pipe. The packing filling opening is additionally formed in the sleeve and normally sealed by the sealing cover. When the packing is lost and the pipeline displaces slightly, the sealing cover is opened and the packing is increased or decreased through the packing filling opening. The application range of products is widened through simple operation and the service life of the products is prolonged. The compensator is simple in structure, convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to the field of agricultural greenhouse facilities, in particular to a special compensator for greenhouse insulation pipes. Background technique [0002] Greenhouses are important facilities for large-scale agricultural production. Winter insulation in greenhouses is a big problem. Insulation pipes are also called insulation pipes. According to different main materials, insulation pipes are generally divided into two types, one is steel-sheathed steel composite insulation pipes, and the other is Polyurethane insulation pipe. No matter what kind of insulation pipe, its pipe body is mainly composed of four parts. (1) Working steel pipe: According to the technical requirements of the conveying medium, seamed steel pipe, seamless steel pipe and double-sided submerged arc spiral welded steel pipe are respectively used. (2) Insulation layer: use rigid polyurethane foam. (3) Protective shell: high-density polyethylene or fiberglass. ...
