Digital-type electric-control gas adjusting valve

Abstract

A digital-type electric-control gas adjusting valve is composed of a base, electromagnetic valves and valve cores. The base is provided with an air incoming passage, an air outgoing passage, an air inlet and an air outlet, a normally-open through hole is communicated with a group of controlled through holes between the air incoming passage and the air outgoing passage, one valve core with small holes is disposed in each of the normally-open through hole and the controlled through holes, and each controlled through hole is controlled by one electromagnetic valve correspondingly. Cross section areas of the small holes of the valve cores in the controlled through holes are different, and relation of the cross section areas is multiple relation. Total open area from the air inlet to the air outlet is related to number and position of the electromagnetic valves which are opened, and the total open area abides by 8421yd. The digital-type electric-control gas adjusting valve is simple in structure and high in reliability, and can be controlled by a single chip microcomputer quite conveniently to form an intelligent constant-temperature control device so as to realize effects of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a gas regulating valve, in particular to a digital electric control gas regulating valve. Background technique [0002] Since the gas water heater consumes a large amount of oxygen and releases a large amount of carbon monoxide and carbon dioxide during work, the gas water heater must be installed outside the bathroom, which brings trouble to the adjustment of the water temperature. At present, most people's practice is to first increase the water temperature outside the bathroom, and then mix cold water in the bathroom through the water mixing valve to adjust the water temperature to an appropriate temperature. This wastes both gas and water resources, isn't it method of energy saving and emission reduction. [0003] There are also some technical solutions that can adjust the water temperature in the bathroom, but most of them are complex in structure, inconvenient to install, poor in reliability, and difficult to be controll...

AI Technical Summary

Problems solved by technology

[0002] Because the gas water heater consumes a lot of oxygen and releases a lot of carbon monoxide and carbon dioxide when it is working, the gas water heater must be installed outside the bathroom, which brings trouble to adjust the water temperature

At present, most people's practice is to first increase the water temperature outside the bathroom, and then mix cold water in the bathroom through the water mixing valve to adjust the water temperature to an appropriate temperature. This wastes both gas and water resources, isn't it Ways to save energy and reduce emissions

[0003] There are also some technical solutions that can adjust the water temperature in the bathroom, but most of them have complex structures, inconvenient installation, poor reliability, and are not easy to be controlled by a single-chip microcomputer to form smart products
