The gas emergency cutting valve is used in equipment failure, corrosion damage, sealing failure, leakage, or emergency, to cut off the source of upstream hazardous materials, avoid the expansion of the scope of the accident, control the impact of accidents, and reduce the loss of accidents.The gas emergency cut valve is a practical and environmentally friendly cutting valve invented by Zhang Gong, a retired senior engineer of the Shanghai Yonglong Valve Factory.
Working principle of gas emergency cutting valve
The working principle of gas emergency cutting valve is: 1. The valve is in a regular open state in daily work, and the electromagnetic valve coil is in a power -off state and does not consume electricity.2. When the accident occurs, the valve coil is transmitted instantly, and the trigger valve is quickly closed to enter the self -locking state.At this time, even if the power is removed, the valve is still self -locking and will not be automatically opened.3. The valve uses a pilot valve petal, which is easy to turn on. Even if the pressure reaches 6BAR, it is very easy. The caliber is greater than DN125. The leveraged handle is used to make the valve achieve the effort and quickly.
Gas Emergency Reverandry Valve Standard
The product standards for gas emergency cutting valve mainly include scope, terms, product classification, technical requirements, test methods, testing rules, signs, instructions, packaging, transportation and storage.In the writing format, we carefully abide by the relevant requirements of GB/T1.1-2000 and GB/T1.3-1997; in terms of standard content, the explosion-proof performance of the product mainly adopts the GB3836 series standard, and other performance indicators are TSGD2002-2006 "Based on the pressure pipeline component type test rules, the main terms of JB/T7352 "Industrial Process Control System" and JB/T9094 "LPG Equipment Technical Conditions for Emergency Disting Valves" are the content of the relevant terms.
Gas emergency cutting valve price
The combustible gas controller is about 200 yuan. If the gas detector, one is about 1,000 yuan/set, the price of the cutting valve is similar to the price of the detector.The ZCR gas emergency cutting valve in the gas supply pipe network of the city or factories can be indoor in the central control room. The valve function and working principle. This series of valves.
