The Chinese speak or sing alternately of ISO/TC153, ISO/TC/153/SC1/SC2, ISO/TC185 technical orgnaization. Duty makes valve trade extended program is mixed in country and occupation standard annual plan, examine the national level of valve industry and occupation standard, responsible to standard content, the announce of responsible standard putting in a mouth 's charge as string of 1000 cash and explain, be in charge of the standardization technology research of valve industry. Limits putting in a mouth 's charge is in charge of the whole nation actuating device of the valve of high school low pressure with all sorts of qualitative material of general, special purpose, valve, press protection too the standardization of the professional domain such as safe device works. Enclothe a product to general, power station is used, water supply is used, petrifaction uses the shut-off valve that waits for a respect to use, check valve, ball valve, butterfly a powerful person, brake a powerful person, pressure-relief valve, relief valve, diaphragm valve, drain valve to wait, and the actuating device of these valve.
