Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of high-temperature abrasion-resistant ball valve of long service life.
For achieving the above object, the utility model provides following technological scheme: comprise valve body, in described valve body, be provided with the spheroid that is driven rotation by valve rod, described spheroid both sides be provided with coordinate with ball seal valve seat, it is characterized in that: between the outer circumferential face of described valve seat and valve body, be provided with installation cavity, in described installation cavity, be installed with and have elastic component vertically between valve seat and valve body, described valve seat and valve body are provided with Sealing between the opposing side of the axial two ends of installation cavity.
By adopting technique scheme, set up installation cavity, elastic element is set in installation cavity, guarantee that valve seat can be pressed in spheroid, secondly the axial two ends of installation cavity arrange Sealing, thereby guaranteeing that mobile medium can not enter installation cavity corrosion elastic element or be stuck in impact between the gap of elastic element continues to use, greatly extend working life.
The utility model is further set to: the described Sealing away from spheroid one end is comprised of several first seal rings and trim ring, the first described seal ring and trim ring are that cross section is the annular component of right-angled trapezium, and the first described seal ring and trim ring fit along the hypotenuse of the right-angled trapezium of valve body axial interval successively setting and adjacent the first seal ring and trim ring.
By adopting technique scheme, spaced the first seal ring and trim ring are coordinated and when being subject to valve seat and valve body pressure, are mutually pushed further increase sealing by inclined-plane.
The utility model is further set to: described elastic element is dish spring, and described dish spring two ends offset and join respectively and between valve seat and the sagittal plane of the first seal ring.
By adopting technique scheme, dish spring load is large, and stroke is short, and requisite space is little, be well suited for being arranged in narrow and small installation cavity, and the large advantage of loading can guarantee coordinating between valve seat and valve body, offsets to join to form with supporting of valve body join with the first seal ring.
The utility model is further set to: the Sealing of described close spheroid one end is O type circle, and the described valve seat position corresponding with O type circle is provided with mounting groove.
By adopting technique scheme, the medium of opposite side impacts less, O type circle is set and can meets seal request, has also reduced cost of production, more meets practicability.
The utility model is further set to: between described valve seat and spheroid faying surface, be provided with the second seal ring, the position that described valve seat is positioned at the second seal ring is provided with V-notch, and the second described seal ring is divided into two-part by V-notch.
By adopting technique scheme, V-notch is set by second seal ring difference two-part, reduce the fitting area of each several part and spheroid, reduce the active force being subject to of each several part, increase the service life, V-notch is also convenient to the timely discharge of impurity, avoids impurity second seal ring that repeatedly weares and teares.
The utility model is further set to: the material of the first described seal ring is graphite, and described trim ring material is 304 stainless steels.
By adopting technique scheme, it is tightr that two kinds of different impurity of hardness coordinates when laminating, and 304 stainless steels are antirust, high temperature resistant is well suited for being applied to high-temperature abrasion-resistant ball valve.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
