Abstract
The utility model discloses a kind of antifreeze corrugated tube water pressure gauge, belong to instrument field.This antifreeze corrugated tube water pressure gauge comprises gauge outfit, joint, and joint is enclosed with anti-overheating layer, zone of heating, thermofin outward successively; Anti freezing solution is filled with in described anti-overheating layer; Described zone of heating is the cavity formed between anti-overheating layer and thermofin, and zone of heating and thermofin have two symmetrical through holes; Described through hole has been each passed through inlet channel and outlet conduit to zone of heating.The inaccurate problem of measurement that the water pressure gauge adopting the utility model effectively to solve outdoor use causes because of cold.
Description
Technical field
The utility model relates to instrument field, specifically a kind of antifreeze corrugated tube water pressure gauge.
Background technology
In water system, hydraulic pressure represents requisite measurement instrument, outdoor use of being everlasting.Water pressure gauge is before installation of dispatching from the factory, and there is the cavity of certain volume water pressure gauge inside, and in use, medium can enter this part cavity on a small quantity and produce pressure, compression elastic element.But use in the open, particularly cold season, the water entering water pressure gauge may freeze in condensation, and build-up of pressure is measured inaccurate, more very causes the flexible member permanent deformation of water pressure gauge to lose efficacy.Inaccurate measurement, may cause the excessive aqueduct of pressure in water supply process to break.
Utility model content
The utility model aims to provide a kind of antifreeze corrugated tube water pressure gauge, to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of antifreeze corrugated tube water pressure gauge, comprises gauge outfit, joint, it is characterized in that: joint is enclosed with anti-overheating layer, zone of heating, thermofin outward successively; Anti freezing solution is filled with in described anti-overheating layer; Described zone of heating is the cavity formed between anti-overheating layer and thermofin, and zone of heating and thermofin have two symmetrical through holes; Described through hole has been each passed through inlet channel and outlet conduit to zone of heating.
Further, the corrugated tube as pressure conduction device is provided with in described joint.
Further, described thermofin is filled with isocyanurate foam.
Further, described inlet channel and outlet conduit are connected to heater, form circulating line loop.
The beneficial effects of the utility model are:
One, adopt corrugated tube as pressure transmitter, even if when after the water freezing in corrugated tube surrounding gap, cause corrugated tube to produce deformation, the deformation of corrugated tube also can not affect the pressure conduction performance of corrugated tube.
Two, be provided with anti-overheating layer outside joint, be built-in with anti freezing solution, the temperature overload when heating is avoided in the setting of anti-overheating layer, causes boiling or the distillation of water.
Three, inlet channel and outlet conduit are connected to heater, form circulating line loop.With heater heating, adopt circulating hot water heating, economical and practical, required cost is low, and structure is simple.
Four, thermofin is filled with isocyanurate foam, and isocyanurate foam has insulation and the novel synthetic material of waterproof dual-use function, effectively can carry out isothermal holding to water pressure gauge, ensures that heat can not scatter and disappear very soon.
Accompanying drawing explanation
Fig. 1 is the antifreeze corrugated tube water pressure gauge structural representation that the utility model provides.
Mark in figure: 1 be gauge outfit, 2 be joint, 3 be corrugated tube, 4 be anti-overheating layer, 5 be zone of heating, 6 be outlet conduit, 7 be thermofin, 8 for inlet channel.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described further.
As shown in Figure 1, a kind of antifreeze corrugated tube water pressure gauge, comprises gauge outfit 1, joint 2, is provided with the corrugated tube 3 as pressure conduction device in joint 2, and joint is enclosed with anti-overheating layer 4, zone of heating 5, thermofin 7 outward successively; Anti freezing solution is filled with in described anti-overheating layer 4; Described zone of heating 5 is the cavity formed between anti-overheating layer 4 and thermofin 7, and zone of heating 5 and thermofin 7 have two symmetrical through holes; Described through hole has been each passed through inlet channel 8 with outlet conduit 6 to zone of heating 5, and inlet channel 8 and outlet conduit 6 are connected to heater, form circulating line loop.Described thermofin 7 is filled with isocyanurate foam.
In use, fill anti freezing solution by anti-overheating layer 4, anti freezing solution does not fill up whole anti-overheating layer 4, leaves certain surplus, avoid heating rear expansion and damage pressure tapping 2, and build-up of pressure is measured inaccurate.Adopt corrugated tube 3 as pressure transmitter, even if when after the water freezing in corrugated tube 3 surrounding gap, cause corrugated tube 3 to produce deformation, the deformation of corrugated tube 3 also can not affect the pressure conduction performance of corrugated tube 3.Heater passes into hot water or water vapour from inlet channel 8 to zone of heating 4, can carry out pressurized treatments as the case may be to improve heating-up temperature.Hot water is got back to heater from outlet conduit 6 and is reheated, and forms the pipeline loop of circulation, simple and practical, easily realizes.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
