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] Such as Figure 1-4As shown, the present invention provides a technical solution: an antifreeze water meter, including 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 central axis of the left connecting flange 2 A water inlet 4 is provided at the right connecting flange 3, and a water outlet 5 is provided at the middle 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. Inside the housing 6 A connecting sleeve 8 is provided, and the upper and lower ends of the connecting sleeve 8 are circularly provided with through holes, and the through holes are punched obliquely along the tangential direction of the circle. The pad 7 is in contact with the central axis of the partition plate 9. A connectin...

Embodiment 2

[0035] Antifreeze cover is plastic material in embodiment 1, and its raw material comprises by weight: 110 parts of ABS resins, 55 parts of polyamides, 15 parts of nano silicon dioxide, 157 parts of mesoporous molecular sieves SBA-157 parts, wollastonite fiber 6 parts, 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. Compound A has the following structural formula:

[0037]

[0038] The antifreeze cover in Example 1 is prepared according to the following steps: take ABS resin and polyamide according to the proportion and mix them evenly, grind for 30 minutes, add nano silicon dioxide, mesoporous molecular sieve SBA-15, wollastonite fiber, antifreeze agent, UV powder , antioxidant, benzophenone, and zinc soap are mixed evenly, blended at a temperature of 120°C, transferred to a twin-screw extruder for masticat...

Abstract

The invention relates to an anti-freezing water meter which comprises a water meter body. A shell is arranged at the middle end of the water meter body, a connecting sleeve is arranged in the shell, apartition plate is arranged at the top of the connecting sleeve, and the two ends of the partition plate make contact with anti-freezing pads respectively. A protection pad and a heating pipe are arranged, and when the temperature is low, a heating wire is started to generate heat, heat is released to the water meter body, so that the water meter body is prevented from being frozen and affectingthe life of residents. An anti-freezing cover is arranged to protect a dial plate, so that the situation in which the device is damaged due to frost cracking of the dial plate is prevented, the situation in which the interior of the water meter body is frozen or the dial plate is damaged by freezing is effectively prevented, the service life of the water meter body is prolonged, the anti-freezingeffect of the water meter body is enhanced, and safety is improved. In addition, the anti-freezing cover used in the invention has a very good anti-freezing 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] A water meter is an instrument for measuring water flow. Most of them measure the cumulative flow of water. They are generally divided into two types: volumetric water meters and speed water meters. 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 normally used, and then choose the water meter of the specification with the usual flow closest to the 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 accuracy of the former is higher than that of the latter, but it has high requirements on water quality and is easy to be blocked whe...
