Combustible gas alarms that have expired for two years are still in use and there are serious security risks. A few days ago, the Changji Bureau of Quality Supervision conducted a special inspection on the use of combustible gas alarms in Changji City and found that 40 alarms were still in use after they expired.
According to reports, in order to strengthen the supervision and management of combustible gas alarms, the inspection team of the Changji Quality Supervision Bureau conducted special inspections on combustible gas alarms used by large hotels, hospitals, schools, and other large public places in Changji City.
During the inspection, law enforcement officers checked 87 flammable gas alarms used by 23 hotels, hospitals and schools in Changji City. Among them, 40 flammable gas alarms used by 12 users exceeded the verification validity period. Some users The use of combustible gas alarms even exceeded the validity period of two years. During the inspection, the law enforcement officers also discovered that some users of flammable gas alarms were not properly regulated. After the first inspection was performed during the installation of the alarms, they were not subject to late-stage management. They did not apply for metrological verification in time after the expiration date, resulting in inaccurate alarms. Some users even wrap alarms with plastic films, and installed flammable gas detection and alarm devices as furnishings. There are great security risks.
According to the staff of the Bureau, according to the relevant provisions of the “Measurement Law of the People's Republic of China†and the “Measures for the Management of Work Measuring Instruments Compulsoryly Tested by the People’s Republic of Chinaâ€, the combustible gas detection alarm relates to personal safety protection and is a kind of prevention of accidents. Safety devices, which are compulsory inspection and measurement instruments, must be included in the scope of mandatory management according to law and must be fixed and fixed.
For the problems detected this time, the Bureau has issued a notice to correct the situation, requiring the inspected unit to apply for verification as soon as possible, and then put it into use after passing the inspection.

Product introduction
1, can be directly installed on the top, side or bottom of the tank, the filter head is exposed outside the tank, the cylinder part is immersed in the tank, thus simplifying the system pipeline, so that the system layout is more compact.
2, equipped with magnets, can filter the oil more than 1 micron ferromagnetic particles,
3, with bypass valve: when the cold oil starts, due to the system liquid temperature is too low, flow pulsation and other factors caused by the filter pressure difference is too large host can not work, and the filter element is blocked by pollutants, the parallel bypass valve at the lower part of the filter cover will automatically open,( 2015730,opening pressure difference is 0.4MPa) to protect the filter element and the system work normally.
4, with a check valve: the filter is placed on the side and bottom of the tank, when replacing the filter, the oil in the tank will not flow out.
5. The flow diffuser is provided. The flow diffuser composed of the lower part of the simplified part can make the return oil flow into the tank smoothly, which is not easy to produce bubbles, reduce the re-entering air, weaken the commotion of deposited pollutants, and can play a coarse filtering role when the bypass valve is opened.
