Abstract
The utility model relates to a kind of anti-selfsealings anticorrosive packing structure that flies out, comprise valve body, valve gap and valve rod, coaxially valve gap is fixedly mounted with in valve body upper end, be shaped with the mounting hole be communicated with valve body in the middle part of valve gap and also coaxially install valve rod, this valve rod lower end is stretched in valve body, valve gap is stretched out in valve rod upper end, the coaxial valve gap Stuffing box surrounding valve rod is shaped with in the mounting hole bottom of valve gap, valve gap above this Stuffing box and valve rod, in valve gap Stuffing box, order is filled with self-sealing packing and filler cover from top to bottom, clamps a circlip in the valve gap mounting hole inner position of filler cover lower end; Between filler cover inner circumferential and valve stem contacts face, coaxial sleeve is equipped with a guide sleeve.The filler assembly of the utility model structure is contained in valve gap lower end, and valve pocket is inner, avoids the corrosion impact of external environment condition to filling-material structure, and this structure effectively prevents filler to be blown simultaneously, and the favorable anti-corrosion effect of filler assembly, selfsealings are effective.
Description
Technical field
The utility model belongs to valve class, relates to high pressure sluice valve, especially a kind of anti-selfsealings anticorrosive packing structure that flies out.
Background technique
At present, the existing filling-material structure of high pressure gate valve mainly loads in Stuffing box from valve gap upper end, then compresses filler by structures such as Glands, plays seal action.Thus, existing filling body is in the process installed and used, and there is filler blowout by the process of Gland compression filler and cause installing failed problem, extraneous factor also may impact filler corrosion simultaneously.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide a kind of design science, structure simple, save space, the anti-selfsealings anticorrosive packing structure that flies out that cost realizes again two ore control function can be saved.
The utility model solves its technical problem and takes following technological scheme to realize:
A kind of anti-selfsealings anticorrosive packing structure that flies out, comprise valve body, valve gap and valve rod, coaxially valve gap is fixedly mounted with in valve body upper end, be shaped with the mounting hole be communicated with valve body in the middle part of valve gap and also coaxially install valve rod, this valve rod lower end is stretched in valve body, valve gap is stretched out in valve rod upper end, it is characterized in that: be shaped with the coaxial valve gap Stuffing box surrounding valve rod in the mounting hole bottom of valve gap, valve gap above this Stuffing box and valve rod, in valve gap Stuffing box, order is filled with self-sealing packing and filler cover from top to bottom, clamps a circlip in the valve gap mounting hole inner position of filler cover lower end; Between filler cover inner circumferential and valve stem contacts face, coaxial sleeve is equipped with a guide sleeve.
And, fill out and valve stem contacts face and be all provided with seal ring between self-sealing packing and the surface of contact of valve gap in selfsealings, and be also coaxially installed with seal ring in the middle part of filler cover periphery.
Advantage of the present utility model and good effect are:
1, the filler assembly of the utility model structure is contained in valve gap lower end, and valve pocket is inner, avoids the corrosion impact of external environment condition to filling-material structure, and this structure effectively prevents filler to be blown simultaneously, and the favorable anti-corrosion effect of filler assembly, selfsealings are effective.
2, be provided with guide sleeve between the utility model valve gap and valve rod, reduce filler to the leading role of valve rod, improve the filler life-span.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing mark representative: 1 valve body, 2 valve gaps, 3 valve rods, 4 circlips, 5 filler covers, 6, guide sleeve, 7 seal rings, 8 self-sealing packings.
Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of anti-selfsealings anticorrosive packing structure that flies out, comprise valve body 1, valve gap 2 and valve rod 3, coaxially valve gap is fixedly mounted with in valve body upper end, be shaped with the mounting hole be communicated with valve body in the middle part of valve gap and also coaxially install valve rod, this valve rod lower end is stretched in valve body and is installed flashboard, valve gap mounting handle or driver are stretched out in valve rod upper end, drive flashboard lifting, open or throttle down by valve rod.
Innovative point of the present utility model is:
The coaxial valve gap Stuffing box surrounding valve rod is shaped with in the mounting hole bottom of valve gap, valve gap above this Stuffing box and valve rod, in valve gap Stuffing box, order is filled with self-sealing packing 8 and filler cover 5 from top to bottom, clamps a circlip 4 in the valve gap mounting hole inner position of filler cover lower end;
In order to ensure the flexible movement of valve rod, between filler cover inner circumferential and valve stem contacts face, coaxial sleeve is equipped with a guide sleeve 6;
Strengthening sealing to prevent from revealing, filling out and valve stem contacts face and be all provided with seal ring 7 between self-sealing packing and the surface of contact of valve gap in selfsealings, and be also coaxially installed with seal ring in the middle part of filler cover periphery.
During installation, filler cover, guide sleeve, seal ring and self-sealing packing are sleeved on valve rod in order successively and form filler assembly, then, the filler assembly formed again loads in valve gap Stuffing box, circlip is installed and by circlip, filler assembly is fixed, filler assembly structure is all inner at valve pocket, avoids the corrosion impact of external environment condition to filler, prevents filler from blowing out simultaneously; Filler pretightening force is regulated voluntarily by cavity pressure; Between valve gap and valve rod, be provided with filler cover and guide sleeve, reduce filler to the leading role of valve rod, improve the filler life-span.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
