Abstract
The utility model provides an automatic compensation type rotating and sealed air-locking discharging valve. A feeding inlet and a discharging outlet are formed in the upper end and the lower end of a valve body of the discharging valve respectively, an impeller composed of a transmission shaft and a separating plate is mounted in the valve body, impeller end plates are mounted on the two sides of the impeller respectively, sealing rings are arranged at the joints of the impeller end plates and the valve body, end covers are mounted on the two sides of the valve body and provided with valve body end covers, sealing pairs are mounted in the valve body end covers on the two sides respectively, an oil cup is mounted on each valve body end cover, and bearings are mounted at the two ends of the transmission shaft respectively. The structure of each sealing pair is that a mechanical seal is mounted between each impeller end plate on the outer circle of the transmission shaft and the corresponding end cover, and a labyrinth sleeve, an oil seal and sealing padding are sequentially arranged on the other side of each end cover and are fixed by a pressing cover. Springs and sealing bars are mounted in end grooves of the separating plate. The sealing devices are arranged in the axial direction and the radial direction of the impeller of the discharging valve, and the discharging valve is good in sealing effect and low in maintenance cost.
Description
Technical field
The utility model relates to valve field, specially refers to a kind of auto-compensating and rotates airtight lock gas discharge valve.
Background technique
Lock wind discharge valve is that pipeline or feed bin band pressure discharge, discharge use one of wider equipment.Generally formed by valve body, impeller, sealing pair and transmission speed reducer structure, on valve body, have charging and discharging mouth.Impeller rotates in valve body, and material is realized the discharging of lock wind through the impeller of over-rotation.
Impeller outer edge in discharge valve used and valve interior wall leave larger fit up gap in the market, generally between 1-5mm.Can cause like this situation generation that pipeline or feed bin internal pressure loss are too fast and leak material.Also there is at present on impeller outer edge fixed configurations seal trim strip to carry out lift-off seal effect; but after having Stamping Steel Ribbon and wearing and tearing with vane rotary and body cavity friction; need to shut down, Stamping Steel Ribbon is adjusted or changed after tearing machine open, and need professional workforce to complete to adjust or change the defects such as operation.
Summary of the invention
The purpose of this utility model is to provide a kind of auto-compensating that utilizes mechanical seal, spring and Stamping Steel Ribbon to realize discharge valve sealing to rotate airtight lock gas discharge valve.
For achieving the above object, the technical solution of the utility model is:
A kind of auto-compensating rotates airtight lock gas discharge valve, comprise material feeding mouth, valve body, bearing, valve body end cap, lubricating cup, dividing plate, impeller end plate, seal ring, mechanical seal, end cap, labyrinth bush, oil sealing, oil filler pipe, stuffing box packing, gland, spring, Stamping Steel Ribbon, discharge port, transmission shaft, sealing pair, the valve body upper end of this discharge valve has material feeding mouth, valve body lower end has discharge port, the impeller being made up of transmission shaft and dividing plate is housed in valve body, impeller bilateral symmetry is equipped with impeller end plate, seal ring is equipped with in the connecting part of impeller end plate and valve body, the monosymmetric end cap that is equipped with of valve body, valve body end cap is housed on end cap, sealing pair is housed respectively in the valve body end cap of both sides, lubricating cup is housed on valve body end cap, lubricating cup is connected with sealing pair by oil filler pipe, bearing is equipped with respectively at the two ends of transmission shaft.
Its structure of described sealing pair is: in transmission shaft outer ring, impeller end plate and end cap are housed, between impeller end plate and end cap, mechanical seal are housed, the opposite side of end cap is equipped with labyrinth bush, oil sealing and stuffing box packing successively, and fixes with gland.
Described dividing plate is equipped with spring and Stamping Steel Ribbon in end grooves.
Good effect of the present utility model is:
1, this discharge valve axially, radially all disposes seal arrangement at impeller;
2, the Stamping Steel Ribbon moment that this discharge valve impeller outer edge configures keeps contacting with valve body, and when after Stamping Steel Ribbon wearing and tearing, Stamping Steel Ribbon automatically compensates under the elastic force effect of spring, to ensure reliable radial seal;
3, impeller shaft disposes labyrinth bush, oil sealing and lubricating point, for ensureing reliable axial seal and lubricated;
4, this discharge valve sealing effect is good, and maintenance cost is cheap.
