As is well known, a water meter is usually installed in a relatively low ground of the outdoors by a water meter. The reason why this can be installed low in the ground is to meet the needs of the waterworks manager who checks the gauge of the water meter at any time to check the water consumption, to perform water piping work inside the building, or to take cut measures when repairing.

Therefore, in view of the above problems, there have been attempts to improve the casting caps made of cast iron pipes in order to improve the problem of frequent breakage of the lid of the water meter protector, and the water meter and the pipe are often freezes due to the cold weather in winter. In order to prevent accidents, there have been attempts to embed thermal insulation materials such as styrofoam around the assembly.

However, in the conventional case, even if a heat insulating material is installed around the protective tube of the water meter, it maintains the temperature in response to a certain temperature drop, but in a cold and cold weather, the external temperature is too cold and suddenly drops so that a separate heat insulating action is performed. Because of the lack of material, cases of freezing and freezing of the meter often occurred, resulting in failure to maintain proper function.

The coating insulation cold-resistant coating is applied to the fastening assembly to have a freeze protection function comprises a colorant, a functional pigment and an additive. The following is a detailed description of their properties and mixtures.

A vehicle serves as a structure of a coating film, which is the final purpose of the paint. In a liquid paint before application, various types of particulate or liquid components constituting the paint are dispersed or dissolved. Formation of the coating film serves to fix these components to the subject.

The coating insulation cold-resistant coating applied to the fastening assembly herein is a one-component water-soluble paint to use a synthetic resin emulsion as a colorant, and these may be selected from vinyl acetate or acrylic resin, natural latex, oligomer (Oligomer) polymer.

Generally, pigments are solid materials having high opacity and hiding power, and become a component that determines the color of the paint. When the coating film is formed, the pigment hides the surface of the subject and exhibits a unique color. In order to obtain, inorganic compounds such as silicon dioxide, aluminum oxide, titanium dioxide, magnesium compounds and calcium carbonate having low thermal conductivity and excellent dispersibility in a colorant can be used as pigments.

Silicon dioxide is a crystalline material with a very low coefficient of thermal expansion. It is characterized by excellent heat resistance and low thermal conductivity. In addition, pure silicon dioxide as well as natural minerals such as high quality diatomaceous earth and siliceous sand are used here. It may be.

Aluminum oxide has excellent heat insulating property with strong chemical properties against acid or alkali, and titanium dioxide has excellent heat insulating property as well as excellent hiding power with acid and alkali resistance.

In addition, magnesium compounds such as magnesite and dolomite, and inorganic compound pigments having excellent thermal insulation and hiding properties such as calcium carbonate may be used.

These inorganic pigments are pulverized and mixed into particles having a particle size of 200 micrometers or less to facilitate dispersion in a colorant, and the mixing ratio thereof is preferably 20w% to 30w% of the total paint before application, and inorganic powders pulverized to 200 micrometers or less. The pigment is smoothly dispersed in the finished paint, but mixing too much amount increases the overall viscosity of the paint, which hinders workability. Since the continuous insulation is not possible, the desired thermal insulation effect cannot be expected, so the mixing ratio of the inorganic pigment is preferably set to 20 to 30% by weight.

The additive serves to secure the formability and firmness of the coating film during workability and painting, and to impart the function of reflecting heat rays after the coating film is completed, and to compensate for the phenomenon of paint flowing during the work, which is a weak point of the existing water-based paint. As the additive, a rubbery material such as natural rubber or synthetic rubber is used, and these solid additives are dissolved and added to ammonia water.

The rubber-ammonia aqueous solution is prepared by mixing rubber and ammonia water in a mass ratio of 1 to 2, respectively, and synthetic rubber such as styrene butadiene rubber, urethane rubber, and acryl rubber may be used as well.

The mixing ratio of the rubber-ammonia aqueous solution is preferably 10 to 20w% of the total paint before coating. In aqueous rubber-ammonia solution, ammonia water is a means for mixing solid rubber and the actual active ingredient is rubber. Rubber gives a minimum viscosity to the paint, which prevents the paint from flowing down during application. By forming elasticity to the coating film at the time of forming the after coating film serves to prevent cracking of the coating film and to ensure durability. Therefore, if the mixing ratio of the rubber-ammonia aqueous solution is too low, the above-described effect can not be obtained. If the mixing ratio is too high, the viscosity of the paint increases, resulting in poor workability. Therefore, the mixing ratio of the rubber-ammonia aqueous solution is 10-20 w. % Is preferred.

The sample used in the present application comprises a paint containing 60 w% of an acrylic emulsion colorant, 25 w% of an inorganic pigment as a diatomaceous earth powder, and 15 w% of an urethane rubber-ammonia aqueous solution having a concentration of 33%. Made of stainless steel was filled with water inside the cap and the cap on the upper and lower, and then coated with an insulating film for cold insulation to store at -20 ℃ for 24 hours and confirmed that the contents did not freeze.

In addition, the present application is to provide a water inlet pipe assembly and a water outlet assembly of a simple structure made of stainless steel, the bent portion or the joint of the conventional water pipe made of cast iron is made of elbows or unions, such as elastic, and the joint portion of the pipe If there is a risk of water leakage due to twisting and leaking, foreign substances can easily enter and corrode, so no matter how clean water is purified and disinfected at the water treatment plant, tap water from each home or building is infected with bacteria or contains a large amount of harmful metals. It does not boil and eat or buy separate bottled water, and the piping structure is a large number of components such as connecting pipe, connecting elbow, guide pipe, hermetic packing, thread at the end of the outlet pipe, connecting elbow and fastening nut. Demanding, and also when a person bends Therefore, it was very cumbersome and had a problem of rising construction cost. Our company is economical in parts cost and construction cost by reducing parts and drastically lowering construction cost. In order to provide a fastening assembly for a water meter which may have usefulness, such as to reduce the cost of the present invention, the present application forms a water pipe having a plurality of corrugated portions made of stainless steel, so that the bent portion is not welded or an elbow is used during the water pipe.
