Description
Technical Field
The utility model relates to a valve especially relates to an anti-crystallization stainless steel ball-rotating valve.
Background
The existing rotary ball valve consists of a valve body, a pressing ring, a valve seat, a valve clack, an upper valve rod, a lower valve rod, an actuating mechanism and other components, wherein the pressing ring is connected to the valve body, and the valve seat is positioned between the valve body and the pressing ring. Under some working conditions of the valve, when a medium contains a large amount of solid particles or contains substances which are easy to scar and crystallize, the medium can enter a gap between the valve body and the valve seat, a gap between the valve seat and the pressing ring, a sealing surface between the valve seat and the valve clack and the like, so that solid particles in the medium are accumulated in the gaps or scar, crystallization and the like are caused, the problems of valve blocking, internal leakage and the like are caused, and the normal service life of the valve is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a thick liquids valve with direction to overcome the above-mentioned not enough that prior art exists at present, make in the medium solid particle be difficult for permeating between disk seat and clamping ring.
The utility model aims at realizing through the following structure, it includes: stainless steel valve body, stainless steel clamping ring are connected to the stainless steel valve body, are the valve pocket in the stainless steel valve body, establish stainless steel disk seat and stainless steel valve lamella in the valve pocket, and the stainless steel valve seat is located between stainless steel valve body and stainless steel clamping ring, and valve rod on the stainless steel is connected on stainless steel valve lamella upper portion, and valve rod under the stainless steel valve lamella sub-unit connection stainless steel, be equipped with the adjustment between stainless steel clamping ring and stainless steel valve seat and fill up, the outer lane of adjustment pad is the stainless steel, and the inner circle of adjustment pad is flexible graphite, and the uncompressed thickness of the inner circle of adjustment pad is greater than the thickness of outer lane, and the outer lane and the inner circle of adjustment pad are connected as an organic whole.
And hard alloy is arranged on the sealing surface of the stainless steel valve clack and the stainless steel valve seat.
And a spring is arranged between the stainless steel pressing ring and the stainless steel valve seat and pressed on the adjusting pad.
The utility model discloses an adopt the adjustment of the different material structures of inner and outer lane to fill up between disk seat and clamping ring, make clamping ring and disk seat realize sealed easily, and in the difficult gap that permeates between clamping ring and disk seat of impurity in the medium to and the adjustment is filled up and is difficult to be corroded by the medium, has improved the life that the adjustment was filled up. And secondly, the hard alloy is arranged on the sealing surface of the valve clack and the valve seat, so that the valve clack is long in service life, and is anti-crystallization and anti-scabbing. Third, be equipped with the spring between stainless steel clamping ring and stainless steel valve seat, make the stainless steel valve seat press on the stainless steel valve clack all the time, realize the utility model discloses a two-way seal. Fourth, adopt stainless steel valve body, stainless steel clamping ring, stainless steel disk seat and stainless steel valve clack its effectively increased the utility model discloses an anticorrosion ability has effectively increased the life of valve.
