Zero leakage quick cut-off bellows gate valve successfully operated

since January 1, 2017, the State Administration of work safety has stipulated that all hazardous chemical tank farms that constitute primary and secondary major hazard sources and are not equipped with emergency shutdown (emergency cut-off) functions should be stopped from using. Due to the comparison of G) results on the domestic super large valve emergency shut-off valve Market: multiple experimental characteristic curves can be superimposed, reproduced and amplified with different colors. There is no such valve yet. The company keenly captures the market opportunities. Since January 1, 2017, the National Safety Supervision Bureau has stipulated that all hazardous chemical tank farms that constitute primary and secondary major hazard sources and are not equipped with emergency shutdown (emergency shut-off) function should be stopped. As there is no such valve in the domestic super large valve emergency shut-off valve market, the company keenly seizes the market opportunity, actively undertakes the task of new product research and development, actively hangs the operator back to its original position, carries out technical exchanges with China Kunlun Engineering Co., Ltd. and Chongqing wankai new material convenient material Co., Ltd., and actively carries out scientific and technological research after clarifying the needs of customers. The R & D team has overcome the rigorous working conditions of large valve diameter, long opening and closing stroke, strong permeability of pipeline medium, short closing time requirements, and easy formation of water hammer during cutting. Therefore, the static friction between the force measuring cylinder and the force measuring piston has changed into dynamic friction effect. The cutting time of 600mm corrugated pipe gate valve is controlled within 20 seconds, and the impact of water hammer effect caused by rapid cutting on the valve is eliminated. Under the condition of full technical exchange and design simulation, the equipment has been in normal operation at the customer's site. The successful research and development of this valve is the first time in the world. It has successfully filled the blank of the emergency shut-off valve for major hazard sources of large-scale chemical plants. It is the patron saint of safety and environmental protection in the chemical industry
