With the vigorous promotion of coal-to-gas conversion, gas water heaters have become popular in northern residential homes. However, incomplete combustion of gas often produces carbon monoxide, which causes poisoning accidents. It is recommended that the heat exchanger and the main burner should be checked at least once a year to see if there is a blockage, and if there is, it should be cleaned in time. At the same time, the fins in the heat exchanger need to be cleaned regularly, and the dirt on the surface must be removed with special tools. Otherwise, it will cause incomplete combustion to produce harmful gases, and in severe cases, poisoning events will occur. Not only must pay attention to safety during use, but also pay attention to check the condition of the water heater after use. Configure an appropriate amount of soap bubbles to apply on the gas path and various joints to check whether there are cracks, aging, and loosening in the gas pipeline and the external rubber hose. In order to prevent gas and carbon monoxide leakage, before using a gas water heater, it must be operated strictly in accordance with the instruction manual and relevant safety gas regulations. The water heater should be cleaned regularly to ensure the normal use of the water heater. In addition, in the "Rules for the useful life of household appliances" approved by the National Standardization Administration Committee, the safe use life of water heaters is clearly stated: electric water heaters are 8 years and gas water heaters are 6-8 years. The water heater has passed its service life, and the user should replace it in time. In addition, in daily life, the following points should be used when using gas water heaters: 1. Regularly check the gas pipelines to avoid leaks in the pipelines; 2 Before each use of the gas water heaters, check whether the ventilation is good; 3. Install the equipment in windy weather The gas water heater's room should be filled with wind or the flue gas water heater should suspend the use of the gas water heater when it pours smoke from the flue; 4. Safety instructions should be given to the use of gas water heaters by minors and foreign relatives to teach them how to use it properly. In addition, choose a suitable home ...

The full name of the independent smoke alarm is an independent photo-electric smoke fire detection alarm, referred to as an independent smoke detector or an independent smoke detector, which is one of the smoke alarm products. The alarm adopts photo-inductive smoke devices and excellent production technology. It is stable in work, beautiful in appearance, simple to install, and requires no debugging. It can be widely used in hotels, stores, Internet cafes, song and dance halls, cafes, leisure halls, houses and other places for fire safety. monitor. Smoke detectors: one is an ion smoke detector, and the other is a photoelectric smoke detector. It has a radiation source 241 inside and outside the ionization chamber. The negative electrode moves. Under normal circumstances, the current and voltage inside and outside the ionization chamber are stable. Once smoke escapes the ionization chamber. The disturbance disturbs the normal movement of the charged particles, causing the current and voltage to change, which destroys the balance between the internal and external ionization chambers, and then sends a signal. There is another type called a photoelectric sensor. It has a light-emitting element and a light-sensitive element. The light emitted by a normal light source passes through the lens to the light-sensitive element. The circuit remains normal. If smoke is blocked from it, the light reaching the light-sensitive element Significantly weakened, so the light-sensitive element changed the change in light intensity into a change in electricity and warned people through the amplifier circuit. There is also a pipe-suction smoke detector, which works similarly to the other scattering type in the photoelectric sensor. It generates light-sensitive current through the reflection or scattering of smoke, which is mainly used on ships. In recent years, laser smoke detectors have also appeared, which also use the principle of photoelectric induction, the difference is that the light source is changed to a laser beam. This type of detector uses semiconductor devices, which are small in size, low in price, vibration-resistant, and long-lived, and have great development prospects.

Natural gas leak alarm is a very important gas safety device, it is the last protection for the safe use of city gas. The gas leak alarm detects the low-concentration combustible gas in the surrounding environment through the gas sensor, and transmits the detection signal to the controller or control circuit with analog or digital quantity through the sampling circuit. When the value is fixed, the controller sends an alarm signal or closes the gas valve through the actuator or the execution circuit. Combustible gas alarms The sensors for detecting combustible gases are mainly oxide semiconductor, catalytic combustion, and hot-wire gas sensors, as well as a small number of other types, such as chemical battery sensors. These sensors all absorb the flammable gas in the surrounding environment and produce a chemical or electrochemical reaction on the sensor surface, which causes the change of the electrophysical properties of the sensor. Gas leak alarms are widely used in many fields such as urban security, residential areas, factories, companies, schools, homes, villas, warehouses, resources, petroleum, chemicals, gas transmission and distribution and so on. Can be used alone, can be used in conjunction with the control, can also be connected to the exhaust fan, solenoid valve, sound and light alarm, automatic reset intelligent control to prevent false alarms, eliminate false alarms, stable and reliable gas leak alarm produced by Shenzhen Pilot Guard Leak alarm, high sensitivity, welcome to inquire.
