Detonation prevention device for gas burner
专利汇可以提供Detonation prevention device for gas burner专利检索，专利查询，专利分析的服务。并且PURPOSE:To miniaturize a titled burner, by so constituting that a solenoid valve whose valve body part has a large diameter, the inside of which is provided with a flame arrester and an outlet side of a large diameter part is made into a small diameter, is arranged in a gas duct, in a home use water heater. CONSTITUTION:A main solenoid valve 13 is installed on a gas boiler from its lower side. When drastic pressure increase is sensed by a piezo-electric element 11 buried in the tip of a plunger 12, an emergency interruption valve is closed by a safety circuit through applicable electromotive force. A flame arrester 8 having a spherical surface resembling closely to a wave surface of a pressure wave is provided above a valve seat 10, and a diameter of the upper part of the arrester 8 is contracted suddenly. In this way, even if a detonation resulting from backfire of a flame occurs energy is absorbed by the flame arrester 8 through a pressure drop as a tube diameter is expanded suddenly at a stage where the flame transfers to the pressure wave in an initial stage of the detonation. Generation of the detonation, therefore, is interrupted. With this constitution, miniaturization of a domestic water heater is possible.，下面是Detonation prevention device for gas burner专利的具体信息内容。
