Gas stove double-coil electromagnetic valve and thermocouple connecting structure with anti-disengaging function

Abstract

The invention relates to a gas stove double-coil electromagnetic valve and thermocouple connecting structure with an anti-disengaging function. An electromagnetic valve connecting part, a thermocoupleconnecting part, a thermocouple assembly and a ground wire terminal are included. The electromagnetic valve connecting part is provided with a connecting support. The thermocouple connecting part isconnected with a thermocouple connecting plastic cap. The ground wire terminal is clamped between the connecting support and the thermocouple connecting plastic cap. The side wall of the periphery ofthe thermocouple connecting plastic cap continuously extends outwards to form a guiding protrusion. A strip-shaped guiding notch is formed in the side wall of the connecting support. The guiding protrusion continuously downwards extends to form a clamping connection cantilever. A clamping connection notch is formed in the side wall of the connecting support. On one hand, on the premise that the ground wire screw installing procedure is omitted, it is ensured that the thermocouple assembly has good grounding performance; on the other hand, the problem about mutual winding of multiple thermocouple wires during batched assembling is solved; and furthermore, the disengaging phenomenon of the electromagnetic valve connecting part relative to the thermocouple connecting part can be avoided.

Description

technical field [0001] The invention relates to the technical field of gas appliance manufacturing, in particular to a connection structure between a double-coil electromagnetic valve and a thermocouple of a gas appliance with an anti-off function. Background technique [0002] The gas solenoid valve is a safety emergency cut-off device for gas pipelines. It can be connected with the gas leakage alarm system or with fire protection and other intelligent alarm control terminal modules to realize on-site or remote automatic / manual emergency cut-off of the gas source to ensure gas safety. When an accidental flameout or harmful strong vibration occurs, the solenoid valve will automatically close. The gas flameout protection devices on the market are mainly composed of thermocouple connection parts, solenoid valve connection parts and thermocouple components. The connecting part of the solenoid valve includes a connecting bracket and a pin assembly. The thermocouple assembly ca...

AI Technical Summary

Problems solved by technology

However, in the actual installation process of the gas appliance, there are the following problems: when the external force is applied, the connection part of the thermocouple is very easy to fall out of the connection part of the solenoid valve

In this way, it will inevitably lead to the failure of the electrical connection between the pin assembly and the temperature-sensing head element and the electrical conduction between the ground wire terminal and the connection part of the solenoid valve, so that a current loop cannot be formed, which will affect the normal use of the gas appliance.
