Top compresses filter element by nut.Stud base can connect with welding with filter cartridge seat, and top nut screwing clamping, on bolt, plays tight
Gu the effect of filter element.
Described adjusting apparatus includes the stud being fixed on cartridge top, and stud runs through blind flange and arranges, between blind flange and stud
Arranging clamp nut, blind flange is fastened by securing member with housing.
Arranging steam drain on described blind flange, housing sidewall arranges discharging hole, discharging hole is positioned at the lower section of outlet.Work as medium
Periodically should discharge excessive gas by steam drain during interior generation gas, prevent blocking circuit phenomenon from occurring.
Between described housing and pipeline, reinforcement is set.Reinforcement can reinforce bend pipe, reduces media flow vibration.
When needs overhaul, should be discharged retaining medium in housing by discharging hole；Open blind flange and extract filter element cleaning maintenance out,
After maintenance, filter element being loaded housing to match with filter cartridge seat, fasten with screw bolt and nut, adjusting apparatus adjusts filter element and installs height
Spend and compress, with sealing gasket, housing being sealed with shell flange lid, it is ensured that the sealing of housing, fasten with securing member.
The beneficial effects of the utility model are:
In housing, import is directly connected to filter element, reduces flow resistance, forms the lowest flow resistance；Avoid showing of medium filtered
As.Filter element screw bolt and nut fastens, and increases sealing；Increase adjusting apparatus on filter element top, adjust filter element setting height(from bottom),
Increase pretightning force and ensure sealing and fastness；Outlet is arranged on bottom and forms backflow with filter element, strengthens circulation area simultaneously, subtracts
Small flow resistance, it is achieved the low flow resistance of secondary；Inlet and outlet is arranged on lower housing portion position, reduces tube hub to filter bottom
Highly, installing space is increased, it is simple to in-site installation and construction.Steam drain is set on blind flange, discharges excessive gas, reduce stream
Dynamic resistance；Lower housing portion arranges discharging hole, it is simple to discharge residual dielectric during maintenance；Discharging hole and steam drain screw thread use NPT pipe
Screw thread, sealing property is excellent.This utility model one is to change original structure, strengthens circulation area and filter area, it is achieved that enter
Go out the low flow resistance of medium；Two is to reduce the setting height(from bottom) imported and exported with bottom, solves and is unfavorable for installation because mouth of pipe height is the highest
Shortcoming；Three is to arrange adjusting apparatus, hold down gag increase filter element tightness, is prone to take out clean filter element simultaneously.
