Problems solved by technology

[0003] However, in the cold winter of the existing water meters, because the weather is too cold, the water in the inner cavity of the water meter is likely to freeze, causing blockage and affecting the normal water use of the family. Therefore, we propose an antifreeze water meter

Embodiment 1

[0031] like Figure 1-4As shown, the present invention provides a technical solution: an antifreeze water meter, comprising a water meter body 1, the left and right ends of the water meter body 1 are respectively fixedly connected with a left connecting flange 2 and a right connecting flange 3, and the left connecting flange 2 has a central axis. A water inlet 4 is provided at the water meter, a water outlet 5 is provided at the central axis of the right connecting flange 3, a housing 6 is provided at the middle end of the water meter body 1, and an antifreeze pad 7 is provided at the bottom and top of the inner wall of the housing 6. A connecting sleeve 8 is provided, the upper and lower ends of the connecting sleeve 8 are annularly provided with through holes, and the through holes are obliquely punched along the tangential direction of the circle. The pad 7 is in contact, a connecting rod 10 is provided at the central axis of the baffle 9, the bottom of the connecting rod 1...

Embodiment 2

[0035] In Example 1, the antifreeze cover is made of plastic material, and its raw materials include by weight: 110 parts of ABS resin, 55 parts of polyamide, 15 parts of nano-silica, 157 parts of mesoporous molecular sieve SBA-157, 6 parts of wollastonite fiber, antifreeze 2 parts of UV powder, 3 parts of UV powder, 1683 parts of antioxidant, 3 parts of benzophenone, 3 parts of zinc soap;

[0036] The antifreeze is composed of formamide and compound A in a mass ratio of 1:1, and compound A has the following structural formula:

[0037]

[0038] In Example 1, the antifreeze cover was prepared according to the following steps: ABS resin and polyamide were weighed and mixed uniformly according to the proportion, ground for 30min, and nano-silica, mesoporous molecular sieve SBA-15, wollastonite fiber, antifreeze, UV powder were added. , antioxidant, benzophenone, and zinc soap are mixed evenly, blended at a temperature of 120 ° C, transferred to a twin-screw extruder for plast...

Abstract

The invention relates to an antifreeze water meter, comprising a water meter body, a casing is arranged at the middle end of the water meter body, a connecting sleeve is arranged inside the casing, a baffle is arranged on the top of the connecting sleeve, and both ends of the baffle are respectively contact with the antifreeze pad. By setting the protection pad and the heating pipe, when the temperature is low, the heating wire is activated to make the heating wire generate heat and release heat to the water meter body, thereby preventing the water meter body from freezing and affecting the lives of residents. Protect the dial to prevent the damage of the device caused by the freezing and cracking of the dial, effectively preventing the occurrence of freezing or freezing damage to the dial in the water meter body, prolonging the service life of the water meter body, enhancing the anti-freezing effect of the water meter body and improving the safety. . In addition, the antifreeze cover used in the present invention has a very good antifreeze effect.

Description

technical field [0001] The invention relates to the technical field of water meters, in particular to an antifreeze water meter. Background technique [0002] Water meter is an instrument for measuring water flow. Most of them are cumulative flow measurement of water. They are generally divided into two types: volumetric water meter and speed water meter. They originated in the United Kingdom. The development of water meters has a history of nearly two hundred years. , you should first estimate the size and flow range of the flow rate used under normal circumstances, and then select the water meter of the specification with the common flow rate closest to this value as the first choice. Most of the instruments for measuring water flow are the cumulative flow measurement of water. They are generally divided into two types: volumetric water meters and speed water meters. The former has higher accuracy than the latter, but it has high requirements for water quality, and it is e...
