Abstract

The invention discloses a solar anti-freeze bellows pressure gauge and belongs to the field of gauges. The solar anti-freeze bellows pressure gauge comprises a gauge head and a connector. The connector is coated with an overheating preventing layer, a heating layer and a heat insulation layer in sequence. The overheating preventing layer is filled with anti-freeze liquid. The heating layer is a cavity formed between the overheating preventing layer and the heat insulation layer and filled with water. A heating bar is inserted into the cavity. A solar sensing plate connected with the heating bar is arranged outside the heat insulation layer. A connecting through hole is formed in the upper end of the heat insulation layer. By the adoption of the solar anti-freeze bellows pressure gauge, the problem that a water pressure gauge used outdoors is inaccurate in measurement due to the cold weather is effectively solved.

Description

technical field [0001] The invention relates to the field of instruments, in particular to a solar antifreeze bellows pressure gauge. Background technique [0002] In the water supply system, the pressure represents an essential measuring instrument, often used in the open air. Before the pressure gauge is installed at the factory, there is a cavity with a certain volume inside the pressure gauge. When in use, a small amount of medium will enter this cavity to generate pressure and compress the elastic element. However, in open-air use, especially in cold seasons, the water entering the pressure gauge may condense and freeze, resulting in inaccurate pressure measurement, and even causing permanent deformation and failure of the elastic components of the pressure gauge. Inaccurate measurement may cause excessive pressure in the water supply process to rupture the water pipeline. Contents of the invention [0003] The present invention aims to provide a solar antifreeze be...
