Female&Male Brass Valve Butterfly Valve Ball Valve
1.Ball valve is the control part of the pipeline system that can quickly truncate and connect the flow of the javascript:void(0);medium. In the process of use, the valve must be fully open or fully closed and cannot be used as the regulating flow
2.Ball valve has internal and external thread, card sleeve, hot melt connection, valve body and bonnet adopt thermostatic hot forging and tempering process, which greatly improves the mechanical performance and safety factor of valve.Valve pressure test was strictly performed according to GB/t13927-1992 < general valve pressure test > standard, 100% of the test was qualified before delivery.
3.Installation of valve must be carried out by professional personnel with relevant qualification. The deviation of the two ends of the pipe shall not be too large, otherwise excessive pipe installation stress will be produced, resulting in valve damage.When installing the screw, it should wrench the hexagon or octagonal parts of the same side of the thread, not the hexagon or octagonal parts on the other end of the valve, avoiding the deformation of the valve.
4.Valve pipe thread accuracy and effective length strictly enforce ISO228 standard, when installing a tightening must choose corresponding torque wrench or pliers, screwing length of screw thread can effectively, do not lead to excessive pressure in the end, cause valve, sealing surface breakage and leakage.
5.To ensure the normal use of the valve, install the filter at the inlet of the line whenever possible.In order to avoid pipeline pressure or temperature fluctuation to reduce the service life of the valve, corresponding preventive measures should be designed.
6.The ball valve handle is designed according to the use of the valve and the corresponding torque. Do not replace the lever arm, so that the operating torque is too large to damage the valve.In the process of use, the closing speed of the valve should not be too large, otherwise the water hammer effect will be doubled
7.Valve stem seal packing is polytetrafluoroethylene, such as the turbine-tightening cap to compensate the filling when the corrosion leak, replace the packing to remove the media pressure.

purpose
The Venturi Tube (Venturi tube) is divided into the built-in Venturi tube and the inserted Venturi tube according to the structure. Good results have been achieved in the measurement of combustion support, cold wind, gas measurement (blast furnace gas, coke oven gas, converter gas) and boiler primary air, two wind pipe diameter and low flow velocity in the hot blast stove of iron and steel plant. To solve the problems of accurate measurement of various types of gas flow at low pressure, large diameter and low flow rate in existing industrial enterprises. A fluid measuring device with wide measuring range and convenient installation. The unique structural design and data processing methods are based on strict fluid mechanics and are calibrated in the national key wind tunnel laboratory.
It can be widely used in the control and measurement of large diameter fluid in petroleum, chemical, metallurgical and power industries.
Characteristic
(1) the resistance to fluid is small, about 150Pa, so energy consumption is low.
(2) the pressure difference is big, the precision is high, and the measuring range is wide.
(3) good stability and smooth differential pressure.
(4) wide range of application. General gas, flue gas, and blast furnace gas with more impurities will not be blocked for long term use.
(5) easy to install and easy to maintain for a long time.
(6) the front and rear straight sections are shorter than the standard throttling devices, about 1D 1.5D before.
(7) online temperature and pressure self correction integrated structure.
