Leakage phenomenon.
Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, it is provided that
A kind of sealing property is higher, and the high-leak tightness valve with automatic compensation function seals
Structure.
The purpose of this utility model can be realized by following technical proposal: a kind of high sealing
Property valve sealing structure, including valve gap, valve rod and gland, it is heavy that described valve gap is provided with
Poroid axis hole, and valve rod is located in axis hole, and be additionally provided with on axis hole and open at valve gap top
The seal groove of mouth, described gland is enclosed within valve rod and fixes with valve gap, and at the bottom of gland
In end embedding sealing groove, it is characterised in that: also include the sealing device being located in seal groove,
Sealing device includes the round shell-like sealing shroud being enclosed within valve rod, sealing shroud cross section indention,
And have some with valve rod outer wall sealing in the annular of laminating, and have some with
The annular outer seal portion of seal groove cell wall laminating, also includes being separately fixed at sealing shroud two
The circular connection of end has compression between ring, and connection ring above and gland bottom
Spring.
Owing to sealing shroud is enclosed within valve rod, and sealing shroud is respectively provided with and fits with valve rod outer wall
Some interior sealing, and have and seal groove cell wall laminating some outer seal portion,
Therefore can improve the sealing effectiveness of entirety, after the interior sealing of sealing shroud weares and teares, can lead to
Overcompression spring force, makes sealing shroud compress, and makes adjacent interior sealing mutually near also
Continuous extrusion valve rod outer wall, therefore has automatic compensation function, it is to avoid owing to sealing shroud grinds
Sealing is caused to be deteriorated after damage.
In above-mentioned a kind of high-leak tightness valve seals structure, described compression spring top
End is further fixed on and the connection ring of gland bottom laminating.
Therefore overall structure is more stable.
In above-mentioned a kind of high-leak tightness valve seals structure, in described sealing shroud also
It is embedded with the tabular reinforcing plate identical with sealing shroud shape.
Therefore sealing shroud intensity can be made higher.
In above-mentioned a kind of high-leak tightness valve seals structure, described sealing shroud is rubber
Glue is made.
Compared with prior art, this utility model has the advantage that
Owing to sealing shroud is enclosed within valve rod, and sealing shroud is respectively provided with and fits with valve rod outer wall
Some interior sealing, and have and seal groove cell wall laminating some outer seal portion,
Therefore can improve the sealing effectiveness of entirety, after the interior sealing of sealing shroud weares and teares, can lead to
Overcompression spring force, makes sealing shroud compress, and makes adjacent interior sealing mutually near also
Continuous extrusion valve rod outer wall, therefore has automatic compensation function, it is to avoid owing to sealing shroud grinds
Sealing is caused to be deteriorated after damage.
