Pujieneng's new structure Blackwater angle valve equipment has won the national invention patent

recently, a new structure Blackwater angle valve equipment designed and reconstructed by the instrument maintenance center of pujieneng chemical company has won the "invention with technological innovation as the core patent certificate" issued by the State Intellectual Property Office. The invention solves the production problem of the company, which has been disturbed for a long time. Although it is far beyond the range of 2.4 (6) 00kn of 600kN in Grade 6. It is reported that the first gas of the company is the black water angle valve of the flash system of the crude polishing device. Since the end of 2014, it has been opened.

recently, a new type of structural black water angle valve equipment designed and reconstructed by the instrument maintenance center of pujieneng chemical company has won the "invention patent certificate" issued by the State Intellectual Property Office. The invention solves the production problem that the company has been disturbed for a long time

it is reported that the black water angle valve of the flash system of the gasification unit of the company has been unable to operate stably for a long period of time due to the influence of high pressure and high flow rate black water medium since it was started up at the end of 2014. After many studies and discussions, the technicians of the center optimized the valve structure, changed the valve body from one-piece to split type, extended the guide sleeve, made the end face flush with the reducing flange surface at the bottom of the valve, and made corresponding technical modifications to the inner cavity of the valve body, the lining of the guide sleeve, the valve seat support ring, etc., so as to ensure the smooth operation of six Texaco gasifiers

at present, the valve after preliminary technical transformation has a good effect in the process of use. After a complete cycle of on-line use of the valve, cracks will increase. After disassembly and inspection, it is found that the valve internals, valve chamber, guide sleeve lining, etc. are basically intact, and have the conditions to continue on-line use. (Yan ting)
