Description
Technical field
The utility model relates to ethylene oxide device loading catalyst pressure difference test meter.
Background technology
At present, the pressure difference test meter that ethylene oxide device loading catalyst adopts, due to ball valve, the air inlet head of tubular discharge and side thereof, the tensimeter of opposite side and joint, discharge and Catalyst packing tubulation jointing are flat seal, discharge is straight tube, cause measurement gas poor sealing performance, measure numerical value and forbidden, there is certain deviation, sometimes need repetitive measurement, waste time and energy.
Summary of the invention
The purpose of this utility model is to solve prior art Problems existing, provides a kind of good seal performance, measures a kind of ethylene oxide device loading catalyst pressure difference test meter accurately.
Technology official documents and correspondence of the present utility model is: ethylene oxide device loading catalyst pressure difference test meter, mainly comprise, air inlet ball valve and pipe adapter, tensimeter and pressure tapping, seal, it is characterized in that: draft tube joint is connected with the surge tank side be provided with through ball valve, and surge tank opposite side is connected with tensimeter by pressure tapping, surge tank wireway lower end and beds load tubulation and are connected; Wireway lower end and beds load between tubulation and adopt seal to be wedge-type seal cover, and wireway internal diameter is surge tank 1/2nd, is positioned at conduit gas middle and lower part and is provided with pedal.
The utility model has following substantive features and remarkable result:
(1) surge tank be provided with is wireway diameter two times, makes measuring instrument possess certain surge capability on the whole, plays stable bleed pressure, reduces the effect of pressure surge.
(2) wedge-type seal cover is installed in surge tank wireway lower end and loading catalyst bed tubulation joint, further increases sealing property.
(3) be positioned at conduit gas bottom (wedge-type seal cover top) and pedal has been installed, ensure delivery line lower end and loading catalyst bed tubulation joint sealing effectiveness, handled easily.
(4) significantly improve measurement accuracy rate, ensure process units more even running after catalyst changeout, alleviate labor intensity of operating staff.
Accompanying drawing explanation
Fig. 1 is ethylene oxide device loading catalyst pressure difference test meter structural representation.
In figure, 1, beds filling tubulation; 2, wedge-type seal cover; 3, pedal; 4, wireway; 5, tensimeter; 6, pressure tapping; 7, surge tank; 8, ball valve; 9, draft tube joint.
Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is further described as follows:
See Fig. 1, ethylene oxide device loading catalyst pressure difference test meter, mainly comprise air inlet ball valve 8 and draft tube joint 9, tensimeter 5 and pressure tapping 6, seal, it is characterized in that: draft tube joint 9 is connected with surge tank 7 side be provided with through ball valve 8, and surge tank 7 opposite side is connected with tensimeter 5 by pressure tapping 6, surge tank wireway 4 lower end and beds load tubulation 1 and are connected; It is that wedge-type seal overlaps 2 that wireway 4 lower end and beds load the seal adopted between tubulation 1, and wireway internal diameter is surge tank 1/2nd, is positioned at conduit gas middle and lower part and is provided with pedal 3.
During use, operator is fixing described pressure difference test meter above Catalyst packing bed tubulation, with foot-operated firmly pedal, make sealing good, then opening ball valve makes required gas enter in surge tank, and through wireway enter beds filling tubulation in, by observe pressure gauge reading, judge each tubulation institute loading catalyst of beds whether qualified (basis for estimation is: within (measured value-measurements mean value/measured value) X100%=± 5% error be qualified.
