At 6:50 in the morning of September 2, after Master Zhang got up, he found that the lithium battery of the battery car being charged in the living room was dripping, the battery was heating up, and because of the fear that the battery dripped water to stain the living room floor, Master Zhang would take the lithium battery being charged. Go to the bathroom to charge. After Master Zhang moved the battery into the toilet, Zhang Weiwei, the son of Gaosan, happened to go to the toilet. When the son entered the bathroom for less than three minutes, he heard a huge explosion, and the battery being charged exploded and ignited the bathroom. After hearing the sound, Master Zhang rushed into the bathroom to see that his son had become a fireman. He quickly extinguished the fire on his son and called 120, 119 for help. Soon the ambulance came to send his son to Xijing Hospital for rescue. It is understood that after the battery explosion caused his son to burn severely, Mr. Zhang has contacted the sales store. At present, the store has notified the electric vehicle manufacturer in Tianjin to rush to Xi'an as soon as possible to handle the battery explosion. It was learned from the hospital that Xiaowei’s body burn area reached 48%, which was a deep third degree burn. The burns of the lower limbs and the double forearms were the most serious, and because Xiaowei was in a confined space in the event of a fire, he burned the respiratory tract and was sent to the hospital. After the occurrence of severe shock symptoms, life is at risk. The hospital passed the treatment of first aid and wound dressing, anti-shock, anti-infection, etc. Xiaowei's condition is gradually stabilized, but because the burn wound is too deep, the infection and some complications are still a fatal factor threatening Xiaowei, and later treated, if Xiaowei was able to survive the infection and was basically out of danger. Special reminder: Overcharging of electric vehicle battery will cause explosion The explosion of an electric car is actually a very small probability. The main components that can cause an electric car to explode are actually mainly on the battery. The most taboo of the battery is overcharging or discharging; when the battery is charging, especially when overcharging, gas (oxygen and hydrogen) will be electrolyzed. If the ventilation is not smooth, the battery will explode. Therefore, pay attention to keep the vent of the electric vehicle unblocked. Charging time should not be too long, and pay attention to the battery temperature, such as more than 45 ° C, should stop charging. In this way, not only will the electric vehicle explosion not occur, but the service life of the electric vehicle will be prolonged.
Butterfly Valve is from a family of quarter-turn valves. Butterfly valve is typically used to regulate a fluid flowing through a section of pipe. A flat circular plate is positioned in the center of the pipe. The plate has a shaft through it connected to an actuator on the outside of the valve. Rotating the actuator turns the plate either parallel or perpendicular to the flow. Unlike a Ball Valve, the plate is always present within the flow, therefore a pressure drop is always induced in the flow regardless of valve position.
There are different kinds of butterfly valves, each adapted for different pressures and different usage.
Butterfly valves are relatively easy to maintain. The resilient seat is held in place by mechanical means, and neither bonding nor cementing is necessary, Because the seat is replaceable, the valve seat does not require lapping, grinding, or machine work.
Butterfly valve is also a type of flow control device, used to make regulating fluid flowing through a section of pipe.

Wafer Butterfly Valve
High Performance Butterfly Valve
Pneumatic Butterfly Valve
The resilient butterfly valve, which uses the flexibility of rubber, has the lowest pressure rating.
The high performance butterfly valve, used in slightly higher-pressure systems, features a slight offset in the way the disc is positioned, which increases the valve's sealing ability and decreases its tendency to wear.
The valve best suited for high-pressure systems is the Triple Eccentric Butterfly Valve, which makes use of a metal seat, and is therefore able to withstand a greater amount of pressure.
