Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] like figure 1 As shown, an antifreeze bellows water pressure gauge includes a meter head 1 and a joint 2. The joint 2 is provided with a bellows 3 used as a pressure transmission device, and the joint is wrapped with an anti-overheating layer 4, a heating layer 5, and a heat insulation Layer 7; the anti-overheating layer 4 is filled with antifreeze; the heating layer 5 is a cavity formed between the overheating prevention layer 7 and the heat insulation layer 7, and there are symmetrical holes on the heating layer 5 and the heat insulation layer 7 Two through holes; the through holes pass through the water inlet pipe 8 and the water outlet pipe 6 to the heating layer 5 respectively, and the water inlet pipe 8 and the water outlet pipe 6 are connected to the heater to form a circulation pipe loop. The insulation layer 7 is filled with po...

Abstract

The invention discloses an anti-freezing water pressure gauge for a corrugated pipe and belongs to the field of instruments. The anti-freezing water pressure gauge for the corrugated pipe comprises a gauge head and a connector, wherein the connector is sequentially wrapped in an overheating resisting layer, a heating layer and a heat insulating layer. The overheating resisting layer is filled with an anti-freezing solution. The heating layer is a cavity formed between the overheating resisting layer and the heat insulating layer. Two symmetrical through holes are formed in the heating layer and the heat insulating layer. A water inlet pipeline and a water outlet pipeline penetrate through the through holes respectively to enter the heating layer. By the adoption of the anti-freezing water pressure gauge, the problem that measurement is not accurate when a water pressure gauge is used outdoor in cold weather is solved.

Description

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