Detailed description of the invention
As shown in Fig. 1 ~ 3, a kind of soft sealing butterfly valve valve seat construction disclosed in this utility model and the soft seal valve seat of this soft sealing butterfly valve valve seat construction；nullSoft seal valve seat uses rubber to make，Soft sealing butterfly valve valve seat construction includes the soft seal valve seat 1 of annular，Valve seat installed surface 21 on valve body 2 and fixation clip 3，Described soft seal valve seat 1 is fixed on valve seat installed surface 21 through fixation clip 3，Described soft seal valve seat 1 is provided with and seals, with butterfly plate 4, the butterfly plate sealing surface 10 coordinated，It is provided with energy storage groove 11 in the middle part of described soft seal valve seat 1，Energy storage groove 11 is corresponding with described butterfly plate sealing surface 10 position，Energy storage groove 11 axially extends and its one end is the opening running through soft seal valve seat 1 axial end，Described soft seal valve seat 1 forms the inside diameter elastomeric 12 with described butterfly plate sealing surface 10 through energy storage groove 11 segmentation，It is positioned at the external diameter body 13 of outside diameter，And connect the connector 14 of described inside diameter elastomeric 12 and external diameter body 13，External diameter body 13 is fixed between fixation clip 4 and valve seat installed surface 21.For ensureing that soft seal valve seat is fixing reliable, the axial two ends of external diameter body 13 of soft seal valve seat 1 are the most axially extending axially extending projection 131, fixation clip 3 and valve seat installed surface 21 are provided with axial notch 31,22, two axially extending projections 131 are respectively embedded in axial notch 31,22, so that soft seal valve seat fixation is reliable.Certainly the installation of soft seal valve seat may be used without directly being processed to form embedding slot on valve body, the external diameter body of soft seal valve seat is directly inlaid in embedding slot, it can use interference fit to reach fixation, but the installation using fixation clip more soft seal valve seat is more convenient and reliable, therefore preferentially uses fixation clip.
nullAfter the butterfly plate sealing surface of soft seal valve seat is adjacent to contact with butterfly plate，There is frictional force，In butterfly plate motor process，The power of the inside diameter elastomeric of the soft seal valve seat reverse flip by being driven by butterfly plate，There is the hidden danger of inside diameter elastomeric reverse flip，Described energy storage groove 11 opening is towards fixation clip 3，The internal side diameter of fixation clip 3 extends to inside diameter elastomeric 12 position，Inside diameter elastomeric 12 is the most corresponding, and energy storage groove 11 open at one end is axially extending bulge loop 121，Described fixation clip 3 is provided with the locating slot 32 embedded for bulge loop 121，Bulge loop 121 with mobilizable mode matched in clearance in locating slot 32，Both bulge loop 121 along with inside diameter elastomeric 12 along energy storage groove 11 opening carry out elastic deformation time，Bulge loop 121 can be movable in locating slot 32，On fixation clip 3, the internal side diameter towards locating slot 32 forms stopper protrusion 321，Stopper protrusion 321 and bulge loop 121 counter stopper.So inside diameter elastomeric is when recovering certain position, and stopper protrusion carries out backstop to bulge loop, thus prevents inside diameter elastomeric from overturning to internal diameter.
On described fixation clip 3, the outside diameter towards locating slot 32 has radially limited support portion 322, both locating slot 32 was concave groove, radially limited support portion 322 is corresponding with the aperture position of described energy storage groove 11, the external diameter sidewall of bulge loop 121 and radially limited support portion 322 matched in clearance, and bulge loop 121 is spacing with radial direction limited support portion 322 backstop coordinates.When butterfly plate seals with soft seal valve seat, inside diameter elastomeric is compressed along energy storage channel opening, on inside diameter elastomeric, bulge loop is close to radially limited support portion, in bulge loop contact to radial direction limited support portion by backstop, formed to conflict to bulge loop and support, it is thus possible to improve the contact reliability of butterfly plate sealing surface and butterfly plate, it is ensured that sealing reliability.
More corresponding High Pressure Difference operating modes, there is the difference of sealing reliability in the simple elasticity relying on soft seal valve seat itself, the most described energy storage groove 11 is built with Elasticity 5.Elasticity 5 can use spiral elastic ring, or rubber ring, or elastic metallic split ring etc., it is preferable to employ spiral elastic ring.Elasticity can improve the sealed elastic of butterfly plate sealing surface, thus realizes using in the operating mode of more High Pressure Difference.
During valve opening and closing, Elasticity constantly shrinks and extends, and reliable for ensureing Elasticity fixing-stable in energy storage groove, the opening of described energy storage groove 11 is reducing 111.When mounted, owing to soft seal valve seat has elasticity, Elasticity can force opening to open loading energy storage groove, after-opening recover, reducing is spacing to Elasticity, it is possible to prevent Elasticity from skidding off displacement from the opening of energy storage groove, ensure that Elasticity position is installed reliable and stable, thus seal reliable.Wherein, the cross sectional shape of described energy storage groove 11 is circular arc.Under this structure, energy storage groove is easy to process, Stability Analysis of Structures, is difficult to tear, and has more preferable elastic deformability.
Soft seal valve seat is described in detail by above-described embodiment, therefore no longer soft seal valve seat is repeated again.
