The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.

Beekeeping Attention in 2012
Due to the dry weather and little rain that lasted for many years, most of the wild nectar plants in our county died or did not flow. Some of the flowering crops and fruit trees available for bees were also growing poorly due to continued drought. Some died, and others only flowered. Honey, due to the continuous drought caused by the increase of farmland pests and diseases, pesticides are widely used by farmers. The poisoning of honey bees when pollinating crops on crops is serious. At the same time, the cost of beekeeping is increased due to the increase in the price of sugar, especially for western honeybees. . In 2012, the drought situation is still serious. This year's beekeeping production situation is also not optimistic. The beekeeping industry as a “wing of agriculture†should make every effort to maintain the apology industry's development without falling back, so the majority of bee-keepers Should be scientifically reared, because of local conditions, do the following preparations for drought and beekeeping: 1, there must be awareness of drought and promote production, often concerned about the site, radio, newspapers and drought information, adjust the appropriate management measures. 2, feeding water, drought caused by the lack of external water sources, the bee difficult to collect water, in order to add water and increase the humidity required to reproduce within the hive, can take a variety of forms of water. 3, supplement feed, drought caused by the shortage of outside sources of honey, we must always pay attention to bees within the nest feed, feed honey, pollen and a variety of vitamins, so that the group has enough nutrients, strengthen reproduction, lay the foundation for future high-yield nectar . Conditioned powder can be used to supplement the spleen. When adding powdered spleen, cover the honey cover, spray a little water, and add the bees to the side of the spleen. If honey is fed, then honey should be added (4:1 ratio). ,), if rewarded with honey water (1:1), supplemented with sugar (2:1) when feeding white sugar, rewarded with sugar water (1:2) ratio, dissolve with boiling water when adding sugar, add a little Oxalic acid promotes sucrose conversion. It can be fed at night with a feeder. 4. Strengthen management to prevent the occurrence of burglars, reduce nest doors, and prevent honey from spilling when feeding. If accidentally spilled on the beehive, it should be cleaned in time with water. 5, do a good job of follow-up honey source survey, choose a reasonable bee route. 6. Strengthen the monitoring of the epidemic situation of bee-bee disease, and actively promote knowledge of the prevention and control of bee enemies, so as to ensure early detection and early treatment, ensure that there is no major bee-poor outbreak in the year of major drought, and ensure stable and healthy development of colony population. 7. For the Chinese and Western bee farms in the dam area, serious violations of pesticides should be removed from the mountainous or semi-mountainous regions where the pesticides are less harmful.
