Manufacturing process of fuel gas control valve used for fuel gas kitchenware

Abstract

The invention mainly discloses a manufacturing process of a fuel gas control valve used for fuel gas kitchenware. According to the technical scheme, the manufacturing process comprises the following steps of (1) valve body manufacturing, (2) valve core manufacturing, (3) air inlet header pipe, air inlet branch pipe and air outlet pipeline manufacturing, (4) inspection, (5) surface treatment and (6) assembling. The manufacturing process is simple, low in cost and energy consumption and free of pollution, the whole manufacturing procedure is advantageously simplified, and the manufacturing cost is advantageously reduced. According to the control valve manufactured through the manufacturing process, a valve body is good in gas tightness and quality and high in reliability; all parts of metal are uniformly stressed; the internal stress is balanced in change; the metal structure is more stable; using is safer and more convenient; and the fuel gas flow rate can be adjusted according to the fuel gas pressure, so that the purposes of automatic adjustment and automatic closing are achieved.

Description

technical field [0001] The invention relates to a manufacturing process of a gas control valve for gas kitchen utensils. Background technique [0002] In the prior art, valves are widely used in modern society. There are many kinds of valves in the prior art, mainly including ball valves, angle valves, globe valves, etc. The gas valve is a kind of The gas control valve is suitable for various gas medium pipelines such as city gas and liquefied petroleum gas. There is a connection cavity, a valve core is arranged in the connection cavity, a valve stem extending into the connection cavity and linked with the valve core and a handle for driving the valve stem are arranged on the valve body, the rotation of the valve core can adjust the flow of gas. The establishment of gas pipelines facilitates people's lives, but people often forget to close the gas valve after using the gas, causing gas leakage and causing poisoning.

AI Technical Summary

Problems solved by technology

The establishment of gas pipelines facilitates people's lives, but people often forget to close the gas valve after using the gas, causing gas leakage and causing poisoning, etc.

[0003] The general gas valve with explosion-proof function will only cut off the gas passage completely when the gas pressure is too large or leaks, and the cutting speed is slow, and the safety is not high. In addition, this kind of gas control valve can only be fully closed or fully opened. state, only the basic cut-off and all-on functions, but cannot realize the adjustment of the gas flow

Moreover, the casting process of the gas control valve has defects such as serious pollution, high energy consumption, high cost, and complicated process, which makes the product manufacturing efficiency low and the pass rate low. The cast product has sand holes and pores, and the sealing performance is not high. Inferior defects have seriously affected the use of gas control valves and have certain potential safety hazards
