Abstract
The utility model discloses a reduce valve moment of torsion, extension filler life's multi -turn valve device, including valve gap and valve rod, the valve gap is equipped with annotates the fat hole, with it is equipped with the spacer ring of moulding plastics to annotate fat hole intercommunication, it respectively is equipped with round upper lip formula from sealing filler and lower lip formula from sealing filler to mould plastics on the spacer ring below, the upper lip formula is equipped with round graphite from sealing filler's top, the lower lip formula is equipped with the filler backing ring from sealing filler's below. Adopt this scheme to compare with prior art, the packed height reduces 13, compare with 6-7 rings of carbon packing seal structure, the valve moment of torsion reduces 30%, the lip formula is equipped with the spacer ring of moulding plastics in the middle of the sealing filler structure, can inject sealing grease into, can inject sealing grease at any time into in the use, keeps the permanent life who seals up and increase the filler of valve rod filler, reduce the friction torque with the valve rod.
Description
Technical field
The utility model belongs to valving field, particularly relates to the valve of many revolution stem structures.
Background technique
Valve is as liquid, gas medium conveying equipment, the fields such as chemical industry, metallurgy, oil, mine, agricultural are widely used in, in existing valve industry, wherein many revolving structures valve many employings graphite packing sealed valve stem structure, this structure valve torque is comparatively large, and filler is easily extruded in the gap that valve rod coordinates with valve gap, forms wearing and tearing, cause filler short for working life, and valve frequently keep in repair.
Model utility content
In order to solve the problem, the utility model provides a kind of many turning valves device reducing valve torque, extend filler working life.
According to an aspect of the present utility model, there is provided a kind of many turning valves device, comprise valve gap and valve rod, described valve gap is provided with greasing hole, be communicated with described greasing hole and be provided with injection moulding spacer ring, described injection moulding spacer ring upper and lower is respectively provided with lip type self-sealing packing and lower lip type self-sealing packing on a circle.
In some embodiments, the top of described upper lip type self-sealing packing is provided with a circle graphite.
In some embodiments, the below of described lower lip type self-sealing packing is provided with filler gasket ring.
The purpose of this utility model is the filling-material structure in a kind of many turning valves of design, change original graphite packing into lip type self-sealing packing, respectively establish a lip type self-sealing packing up and down, middle place an injection moulding spacer ring, can inject seal gease during use for filler provides pressure to make filler strut sealing.Its beneficial effect is: adopt such scheme compared with prior art, and packed height reduces 1/3; Compare with 6 ~ 7 circle graphite packing sealing configurations, valve torque reduces 30%; Be provided with injection moulding spacer ring in the middle of lip type self-sealing packing structure, can seal gease be injected, in use can inject seal gease at any time, keep the permanent sealing of stem packing and increase the working life of filler; Reduce and the friction torque of valve rod, facilitate the maintenance of filler and extend working life of filler.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-valve gap, 2-valve rod, 3-greasing hole, 4-injection moulding spacer ring, the upper lip type self-sealing packing of 5-, lip type self-sealing packing under 6-, 7-filler gasket ring, 8-graphite.
Embodiment
Be further described below in conjunction with accompanying drawing 1 pair of the utility model.Accompanying drawing 1 schematically shows the utility model many turning valves device, comprise valve gap 1 and valve rod 2, described valve gap 1 is provided with greasing hole 3, be communicated with described greasing hole 3 and be provided with injection moulding spacer ring 4, described injection moulding spacer ring 4 upper and lower is respectively provided with lip type self-sealing packing 5 and lower lip type self-sealing packing 6 on a circle.
Preferably, the top of described upper lip type self-sealing packing 5 is provided with a circle graphite 8.
Preferably, the below of described lower lip type self-sealing packing 6 is provided with filler gasket ring 7.
By reference to the accompanying drawings 1, during installation, first put into filler gasket ring 7, then put lip type self-sealing packing 5 on a circle above filler gasket ring 7, then put into injection moulding spacer ring 4, injection moulding spacer ring 4 is put lip type self-sealing packing 6 again under a circle, finally puts a circle graphite 8, compress.After installation, by the greasing hole 3 on valve gap 1, seal gease can be injected.Facts have proved, adopt the valve torque of this structure obviously to reduce, sealability is more excellent.
Above-described is only mode of executions more of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from creation design of the present utility model; can also make other distortion and improve, these all belong to protection domain of the present utility model.
