Abstract
The utility model discloses a drum vacuum pulp washing engine plane valve sealing device, arranging an exhaust vent 3 between the two fixed flanges 2 through a bolt regulating the clearance gap of the plane valve 1 and a rotary drum 4. The utility model has the advantages of reducing the vacuum area of pulp stripping area, being extremely efficient in sealability and improving vacuum degree to 0.02MPa.
Description
Technical field
The utility model relates to a kind of drum-type vacuum pulp washing machine plane valve sealing means, belongs to pulp technology for making paper.
Background technology
At present, drum-type vacuum pulp washing machine plane valve can not well seal, and it is serious to leak vapour, causes vacuum on the low side, and the slurry washing difficulty is big, and it is high finally to cause industrial chemicals to consume.
Summary of the invention
The purpose of this utility model provides a kind of drum-type vacuum pulp washing machine plane valve that can improve the vacuum and the clean result of wash engine.
For addressing the above problem, solution of the present utility model is: a kind of drum-type vacuum pulp washing machine plane valve sealing means, constitute by plane valve, rotary drum, and it is characterized in that steam vent on the valve of plane is between two mounting flanges.
Adopt the utility model can change the exhaust position in stripping slurry district, reduce the region of no pressure gas leakage of stripping slurry district, reach the purpose of gas clean-up.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
1. flange 3. steam vents 4. rotary drums of plane valve 2. set bolts
The specific embodiment
Regulate the gap of plane valve 1 and rotary drum 4 by regulating bolt, steam vent 3 is placed between two mounting flanges 2, reduced the vacuum area in stripping slurry district, and made its better tightness, wash engine vacuum is brought up to more than the 0.02MPa, help stripping and starch.
