Problems solved by technology

[0003] When the water meter is installed, the positioning rod will be connected. Firstly, it will play the role of fixing and connecting. However, due to the water flow and the weight of the product, it is often easy to rust or break after a long time. The use of ordinary rods The lifespan is not long, and generally there is no regular inspection and inspection by a special person, so many problems often occur

Abstract

The invention provides a method for preparing a stop level of a household water meter, and relates to the field of casting technology for water measuring equipment. The method comprises manufacturing a model, fusing material, mixing material, condensing material, heating material, preparing material, secondly condensing, immersing material and polishing material. The method for preparing the stop level of the household water meter is reasonable, convenient to carry out and good in physical properties of a product.

Description

Technical field: [0001] The invention relates to the technical field of casting of water flow measuring equipment, in particular to a preparation method of a positioning rod of a household water meter. Background technique: [0002] A meter for measuring water flow. Mostly cumulative flow measurement of water. It is 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 it is easy to be blocked when there are impurities in the water. The meter that records the water consumption of tap water is installed on the water pipe. When the user releases water, the pointer or character wheel on the meter rotates to indicate the amount of water passing through. [0003] When the water meter is installed, the positioning rod will be connected. Firstly, it will play the role of fixing and connecting. However, due to the water flow and the weight o...
