Leakage detection device and leakage detection method for gas between main and auxiliary fuel gas solenoid valves

Abstract

The invention discloses a leak detection device and leak detection method for gas between main and auxiliary fuel gas solenoid valves. The leak detection device comprises a fuel gas pipeline, a protection box, a pipe clamping assembly and a fixing plate, wherein the main solenoid valve and the auxiliary solenoid valve are respectively arranged on the pipe wall of the fuel gas pipeline, and a detection pipeline is arranged on the pipe wall of the fuel gas pipeline and between the main solenoid valve and the auxiliary solenoid valve; the protection box is connected with one end of the detection pipeline in a penetrating manner; a packaging cover is arranged on the front surface of the protection box. The pipe clamping assembly is arranged in the packaging cover; the fixing plate is arranged in the protection box, a pressure sensor is arranged at the top end of the fixing plate, and a sealing assembly is arranged at the top end of the fixing plate and located on the front face of the pressure sensor. The leak detection device has the beneficial effects that the gas pressure sensor is additionally arranged between the main electromagnetic valve and the auxiliary electromagnetic valve, whether the main electromagnetic valve and the auxiliary electromagnetic valve leak gas or are damaged or not can be conveniently judged according to the gas pressure change condition between the main electromagnetic valve and the auxiliary electromagnetic valve, locking is conducted in time, and an alarm is given to prompt a user.

Description

technical field [0001] The invention relates to a gas leak detection device and a leak detection method, in particular to a gas leak detection device and a leak detection method between main and auxiliary solenoid valves of gas, and belongs to the technical field of gas detection. Background technique [0002] Gas burners are widely used in boilers and industrial combustion and other fields that require heating applications. They are special equipment products and have high safety requirements. At present, a main switch solenoid valve and a secondary switch solenoid valve are generally connected in series in the gas burner intake pipe. When working, the gas can enter the combustion chamber only when the two solenoid valves are turned on at the same time, so as to ensure the safety of the switch control of the gas pipeline. [0003] In practical application, this method has two disadvantages. One is that this method belongs to one-way control. It only adds a solenoid valve ...

AI Technical Summary

Problems solved by technology

One is that this method belongs to one-way control. It only adds a solenoid valve backup to ensure the safety of the gas switch. The system does not introduce solenoid valve control status feedback. If a solenoid valve is damaged and cannot be closed during use, the system cannot check it. from

In an extreme environment, once two solenoid valves are damaged at the same time, resulting in gas leakage, it will cause immeasurable losses such as explosion

The second is that this method is not conducive to the maintenance of equipment at ordinary times. During equipment maintenance, maintenance personnel can only test the on-off status of the main and auxiliary solenoid valves to judge whether the solenoid valves are working normally. This requires a lot of maintenance time and increases equipment maintenance costs.
