Description
Technical field
The utility model is related to a kind of ball valve, more specifically, more particularly to a kind of pair of spheroid single-direction metal sealing face ball valve.
Background technology
Metal hard-sealing ball valve of the existing high-temperature high-pressure medium bad working environments under, failure-frequency is higher, short life,
The failure such as leakage, leakage, bite in easily occurring.Usual metal hard-sealing of the high-temperature high-pressure medium bad working environments under is transported online
The row time is up to or so half a year, or even two or three months occur as soon as failure, directly affects the safety and economic benefit of user.
The shortcoming that metal hard-sealing ball valve of the high-temperature high-pressure medium bad working environments under is present：
1) spheroid, valve base sealing coating are easily damaged by medium erosion, leakage, short life in serious occur
Existing metal hard-sealing ball valve devises a set of spheroid and valve base sealing, and spheroid and valve base sealing coating are damaged
It is bad that interior leakage just occurs.The life-span of spheroid and valve seat coating, medium was damaged to coating erosion in addition to being influenceed by coating process and quality
Bad is the main cause of metal hard-sealing ball valve short life.
Ball valve is opening moment, and because upstream and downstream relative pressure is larger, passage gaps are smaller, and flow velocity is very fast, now medium
It strong to the generation of ball valve sealing pair coating can wash away, as ball valve switch frequency is continuously increased, wash away increase, medium can be to close
The generation of front cover coating is peeled off and corroded, and finally makes ball valve is seriously interior to leak.
2) valve body at valve bonnet seal with leaking outside
Usual metal hard-sealing ball valve valve body plays sealing by bolt presses sealing gasket with bonnet, but in HTHP
In use, medium temperature, pressure alternately change under bad working environments, valve body can be caused with being leaked outside at valve bonnet seal.
3) there is bite in metal hard-sealing ball valve
Sealing between high-temperature metal hard-sealed ball valve valve seat and valve body generally uses soft graphite, under worst hot case,
The materials such as soft graphite, spheroid, valve seat can produce volumetric expansion, especially soft graphite, and swell increment is big after being heated.Such as fruit structure
It is designed without considering material expansion compensation at high temperature, bite occurs and akinesia in ball valve.
