Description
Technical field
The utility model belongs to sealing device technical field, is related to a kind of improved gas burner base-plate valve stuffing box.
Background technique
Present gas burner has carried out coming into operation for workflow reengineering and moulded coal, and the temperature of each pipeline and base-plate valve is aobvious
Write and increase, it is high up to 350 DEG C generally at 200 DEG C or more, more exacerbate the damage of airtight and watertight padding, general packing seal less than
It begins within one month leak, causes very big waste, while serious polluted environment.
A kind of filling seal device for gas seat plate valve of Patent No. CN200520132002.2 is now disclosed, by interior filler
Box body, wear resistant filler support ring, interior filler, filler connector sleeve, outer filler box body, outer filler, gland and grease box composition.
Interior filler box body and outer filler box body are mounted in the grease box with cavity of sealing, between interior filler box body and outer filler box body
Filler connector sleeve is installed.Interior filler box body lower part is equipped with wear resistant filler support ring, and outer filler box body top is equipped with filler
Gland.The present apparatus can reduce the temperature of airtight and watertight padding, reduce abrasion of the valve rod adherency dust to filler, and packing seal effect is good.
Stuffing box present position be gas burner base-plate valve cover greatly, temperature 120 DEG C -180 DEG C degree between, valve rod every about
10min moves back and forth primary.After running a period of time, flexible graphite packing will harden or loose with valve stem contacts surface
And generate gap；Another aspect valve rod can generate honeycomb point by gas corrosion by long-play；It happens occasionally at sealing
Gas leak must replace filler at this time.It needs to shut down when replacing filler, removes the upper connection of valve rod, remove stuffing box and big
Filler could be replaced after taking out stuffing box after the lower connection of lid.Replacing construction is long, and at least needs two check mans to cooperate and complete more
It changes.Therefore, it is necessary to difficult for replacement according to actual use situation, flexible filler easily hardens the problems such as loose progress structure and changes
Into.
Utility model content
The purpose of the utility model is to overcome deficiencies of the prior art, provide a kind of improved gas burner
Base-plate valve stuffing box.
The utility model is achieved by the following technical programs.
A kind of improved gas burner base-plate valve stuffing box, including box body and valve rod, the box body top are equipped with gland；Institute
Stating valve rod, to be located at box body intracavitary；The box body is intracavitary to be equipped with filler and metal pressure ring；The filler is between valve rod and box body；
The metal pressure ring is between filler and box body；Fastener is equipped on the outside of the box body；One end of the fastener passes through box
Body withstands metal pressure ring.
As further technological improvement, box body internal diameter described above is set as 80mm.
As further technological improvement, gland described above is connect by fixing piece with box body.
As further technological improvement, filler described above uses soft graphite.
As further technological improvement, fastener described above uses outer diameter for the bolt of 10mm.
As further technological improvement, bolt described above uses the bolt of square spigot.
As further technological improvement, fastener described above is using adjusting screw.
The utility model has the beneficial effects that:
The utility model, can in a very short period of time, by fastener to pressure ring when gas leak occurs for filler
Effect is completed to the filler inside stuffing box, to be adjusted.Make up filler filling, valve rod is corroded and filler itself
Defect is generated after running for a period of time.The utility model can increase the service life of base-plate valve, be conducive to production, convenient for inspection
It repairs, save the cost.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the metal pressure ring top view of the utility model.
In figure:
1- valve rod, 2- gland, 3- filler, 4- metal pressure ring, 5- box body, 6- fastener, 7- fixing piece.
Specific embodiment
Be described further below the technical solution of the utility model, but claimed range be not limited to it is described.
As shown in Figs. 1-2, a kind of improved gas burner base-plate valve stuffing box, including box body 5 and valve rod 1, the box body 5
Top is equipped with gland 2；It is intracavitary that the valve rod 1 is located at box body 5；The box body 5 is intracavitary to be equipped with filler 3 and metal pressure ring 4；It is described to fill out
Material 3 is between valve rod 1 and box body 5；The metal pressure ring 4 is between filler 3 and box body 5；It is equipped on the outside of the box body 5 tight
Firmware 6；One end of the fastener 6 passes through box body 5 and withstands metal pressure ring 4.5 internal diameter of box body is set as 80mm.The gland 2
It is connect by fixing piece 7 with box body 5.The filler 3 uses soft graphite.The fastener 6 uses outer diameter for the bolt of 10mm.
The bolt uses the bolt of square spigot.The fastener 6 is using adjusting screw.The effect of screw is fixed metal pressure ring, is adjusted
Whole filler prevents it from generating loosening.
Former stuffing box internal diameter is increased into 80mm, while being turned inner cavity boss, is conveniently replaceable filler 3 in this way.When valve rod 1
Point or filler 3 are generated in the case of a high temperature by corrosion, and when loose with Surface hardened layer at 1 CONTACT WITH FRICTION of valve rod for a long time, filler 3 is pressed
Leakage can be generated at lid 2.3 gland 2 of filler can be opened at this time plus high temperature grease, tightens gland 2, by tightening fastening
Part 6 suitably adjusts metal pressure ring 4, and inner stuffing 3 can compress valve rod 1 under pressure ring effect, and filler 3 can be abundant with valve rod 1
Contact.Achieve the effect that sealing.When gas leak occurs for filler 3, can be pressed in a very short period of time by 6 Duis of fastener
The effect of ring is completed to the filler 3 inside stuffing box, to be adjusted.It makes up filler 3 and is corroded and filled out in filling, valve rod 1
Material 3 itself generates defect after running for a period of time.The utility model can increase the service life of base-plate valve, be conducive to production,
Easy access, save the cost.
