Abstract

A padding plate sealing arrangement for plate valve a coal gas seat includes an inner padding box, an antiwear padding support ring, inner padding, a padding joint sleeve, an outer padding box, outer padding, a padding stressed top and a grease box. The inner padding box with the antiwear padding support ring at its lower part and the outer padding box with the padding stressed top at its upper part are installed in the cavum of the sealed grease box. The padding joint sleeve is provided between the inner padding box and the outer padding box. The arrangement could reduce the temperature of packing material, decrease the wearing of the adherence on the valve stem to the padding, and have a good performance in padding sealing.

Description

Coal gas base-plate valve stuffing seal
Technical field
The utility model relates to a kind of seal arrangement, particularly a kind of coal gas base-plate valve stuffing seal.
Background technique
Common coal gas base-plate valve stuffing seal mainly is made up of support ring, filler, Gland, and this structure has following shortcoming: because of having a large amount of dust in the coal gas, wash away the valve rod of base-plate valve on the one hand; On the other hand, dust adhesion on valve rod, when stem movement, the dust of the adhesion filler that constantly weares and teares, thereby filler is damaged, do not reach sealing effect.Particularly all gas stoves have carried out workflow reengineering now, and the coming into operation of moulded coal, the temperature of each pipeline and base-plate valve significantly raises, generally more than 200 ℃, high reaches 350 ℃, has aggravated the damage of stuffing box packing more, and general packing seal just began to leak less than one month, caused very big waste, simultaneously serious pollution environment.
Summary of the invention
The purpose of this utility model is to provide a kind of temperature, minimizing valve rod that can reduce stuffing box packing to adhere to dust to the effective coal gas base-plate valve stuffing seal of wearing and tearing, the packing seal of filler.
The technical solution adopted in the utility model is: coal gas base-plate valve stuffing seal is made up of interior filler box body, wear resistant filler support ring, interior filler, filler connecting sleeve, outer filler box body, outer filler, Gland and grease box.Interior filler box body and outer filler box body are installed in the grease box of band cavity of sealing, between interior filler box body and the outer filler box body filler connecting sleeve are installed.Interior filler box body bottom is equipped with the wear resistant filler support ring, and outer filler box body top is equipped with Gland.
The utlity model has following advantage: can reduce the temperature of stuffing box packing, reduce valve rod and adhere to the wearing and tearing of dust to filler, packing seal is effective, and is simple in structure, and Maintenance and Repair are convenient.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
