In October, the total output value of instrumentation industry fell to 1.32%

From January to October 2011, the analysis of the main economic indicators of 83 key enterprises in the machinery industry, in terms of total industrial output value, instrumentation dropped from 12.46% to 1.32%.

Statistical calibers—In terms of total industrial output value, the growth rate of construction machinery continued to slow down, and the growth rate of basic parts increased significantly. Environmental protection refrigeration maintained a steady growth trend but the growth rate gradually declined, and mining equipments reversed their trend and continued to heat up. Agricultural machinery, machine tools, The growth rate of automobiles was stable, the growth rate of instrumentation continued to decline, and power equipment and heavy machinery maintained negative growth. From January to October, the industrial output value of the industry was 1,533.2 billion yuan, an increase of 8.21% year-on-year. Judging from the accumulated industrial output value of all sub-industries, the growth rate of construction machinery in October still ranks first in all sub-sectors, but the growth rate has continued to decline, which has dropped from the growth rate of 52.37% in March to 34.72%, but the ratio In September, the growth rate rebounded by 5.48 percentage points: The cumulative growth rate of basic parts total production value in October showed a significant increase to 23.55% year-on-year, which was ranked second, mainly due to the lower monthly production value of basic parts in the same period of last year: Refrigeration and mining equipment, the year-on-year growth rate was 20.58%, 20.24%, environmental protection refrigeration fell again by 1.61 percentage points in September; mineral equipment continued to heat up, compared to September slightly increased by 0.62 percentage points; machine tools, automobiles and agriculture Machinery maintained steady growth, with year-on-year growth rates of 13.21%, 10.23%, and 8.04%, respectively; instrumentation and internal combustion engines began to decline at a rate of increase in total industrial output from March, including instrumentation from 12.46% to 1.32%, and internal combustion engine from 14.25. % dropped to -5.33%; electrical equipment and heavy machinery remained negative growth, with growth rates of -6.64% and -13.62% in October.

Accounting caliber—In terms of operating revenue: The growth rate of basic part revenues rose to the top, exceeding the growth rate of construction machinery but slowed down gradually, machine tools and environmental protection refrigeration maintained high growth, mining equipment prosperity rate all the way up, agricultural machinery, The growth rate of internal combustion engines and instrumentation has decreased month by month, and heavy machinery and electrical equipment are still sluggish. Judging from the accumulative operating income growth, from January to October, the entire industry realized operating revenue of 157.813 billion yuan, an increase of 11.97% over the same period of last year. From the perspective of sub-sectors, the accumulative revenue growth of basic components surpassed construction machinery for the first time, a year-on-year increase of 33.46%; cumulative operating income of construction machinery increased by 33% year-on-year. %, still high, but compared to the first half of the growth rate of about 50% decline in the rate; machine tool tools in April to August growth rate remained at around 27%, September growth slowed, in October year-on-year growth It rose to 28.71%; environmental protection refrigeration maintained a high growth rate of about 25% during the peak season in June-August, and further increased to over 27% in September and October; the cumulative operating income of agricultural machinery and internal combustion engines increased in March. They were 20.45% and 29.72% respectively, but this year the industrial boom has been declining all the way, and the cumulative year-on-year growth rate of revenue has decreased month by month. In October, the growth rate has dropped to 10.10% and 8.18%; the auto industry's growth rate from May to October is The 15.78% in April decreased, staying at around 11%, of which the growth rate was 11.84% in October; mining equipment showed negative growth from February to June, and the industry boom started all the way since July and the revenue growth maintained. About 11%, in October rose to 14.25%; instrumentation operating income growth month by month, has dropped from 12.26% in March to 0.68% in October; heavy machinery, power equipment, the cumulative operating income growth continued negative growth The growth rate in October was -3.11% and -18.28% respectively.

Lift check valves are also called piston check valves. They are essentially globe valves without the stem and top works, allowing the disc to respond to flow rates and direction. The disc has linear movement and is typically body-guided with conical seating surfaces. Springs can be added above the disc to provide more closure force when the disc returns to its closed position. Some manufacturers include externally attached equalizer piping to increase the disc opening with lower flows. The equalizer pipe is an open-pressure communication device that maintains equal pressure above the disc and in the piping downstream of the disc.

Depending on the valve body configuration (Y-pattern, angle, or T-pattern), the pressure drop could be close to that of a tilting disc Check Valve or much higher. The disc of this check valve design is stable in any open position and can be used with a wide range of flow rates.
