Abstract
The utility model discloses a kind of antifreeze bellow type liquid filled case, relate to instrument field.This antifreeze bellow type liquid filled case comprises gauge outfit, joint, and liquid storage pipeline is coiled into bellow type and is arranged in joint, and joint lower end is connected with flange; Be enclosed with thermal insulation pipe outside described joint, filled polyurethane foam in thermal insulation pipe, thermal insulation pipe lower end is provided with heat-insulating pipe joint; Described heat-insulating pipe joint is threaded with flange.Adopt the utility model to be effectively incubated pressure gauge, prevent the pressure gauge freezeout when outdoor use cold season.
Description
Technical field
The utility model relates to instrument field, specifically a kind of antifreeze bellow type liquid filled case.
Background technique
In existing line tubular type liquid filled case technology, liquid storage pipeline is set below adpting flange.But liquid filled case exists following problem: when using in the open, particularly the onsite application of water injection well and weather cold season, the liquid in pipeline may freeze, the pressure misregister of build-up of pressure table, brings to life production many unfavorable.Expansion of liquids distortion simultaneously, can cause the liquid storage pipeline permanent deformation of bellow type or break, making be significantly less than theory expectation manometric actual life, bring financial cost.
Model utility content
The utility model provides a kind of antifreeze bellow type liquid filled case, is intended to solve the problem.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of antifreeze bellow type liquid filled case, comprises gauge outfit, joint, it is characterized in that: liquid storage pipeline is coiled into bellow type and is arranged in joint, and joint lower end is connected with flange; Be enclosed with thermal insulation pipe outside described joint, filled polyurethane foam in thermal insulation pipe, thermal insulation pipe lower end is provided with heat-insulating pipe joint; Described heat-insulating pipe joint is threaded with flange.
Further, sealing O shape circle is provided with in described flange.
Further, antifreeze silicone oil is filled with in described liquid storage pipeline.
The beneficial effects of the utility model are:
One, the utility model structure is simple, easily realizes, carrying out isothermal holding, preventing the liquid in pipeline from freezing by adding heat insulation layer structure to pressure gauge.
Two, filled polyurethane foam in thermal insulation pipe, polyurethane foam is the novel synthetic material with insulation and waterproof dual functions, effectively can carry out isothermal holding to pressure gauge, if liquid storage pipeline breaking simultaneously, also can prevent the antifreeze silicone oil in liquid storage pipeline from directly revealing.
Three, sealing O shape circle is set in flange, can seal action be played, prevent from revealing.
Four, liquid storage pipeline is coiled into bellow type, and the space length that pipeline is taken is shorter.
Accompanying drawing explanation
Fig. 1 is the antifreeze bellow type liquid filled case structural representation that the utility model provides.
Mark in figure: 1 be gauge outfit, 2 be liquid storage pipeline, 3 be thermal insulation pipe, 4 be joint, 5 be flange, 6 for sealing O shape circle, 7 be heat-insulating pipe joint.
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 bellow type liquid filled case, comprises gauge outfit 1, joint 4, it is characterized in that: liquid storage pipeline 2 is coiled into bellow type and is arranged in joint 4, is filled with antifreeze silicone oil in liquid storage pipeline 2, and joint 4 lower end is connected with flange 5; Be enclosed with thermal insulation pipe 3 outside described joint 4, filled polyurethane foam in thermal insulation pipe 3, thermal insulation pipe 3 lower end is provided with heat-insulating pipe joint 7; Described heat-insulating pipe joint 7 is threaded with flange 5.Sealing O shape circle 6 is provided with in flange.
After manometric gauge outfit 1, joint 4 being connected with thermal insulation pipe 3, in thermal insulation pipe 3, point fine and closely woven filled polyurethane foam of several, makes polyurethane foam fill up thermal insulation pipe 3, forms fine and close insulating foam layer.Polyurethane foam has insulation and the novel synthetic material of waterproof dual functions, effectively can carry out isothermal holding to pressure gauge, if liquid storage pipeline breaking simultaneously, also can prevent the antifreeze silicone oil in liquid storage pipeline from directly revealing.Making pressure gauge be fixed in flange 5 with heat-insulating pipe joint 7 again, in flange 5, being provided with the sealing O shape circle 6 for sealing.
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 domain of the present utility model.
