Description
Technical field
The utility model is related to a kind of industrial system stop valve, especially a kind of band triangle being applicable in high temperature and high pressure condition
Enclose the all-welded ball valve of screw thread valve seat.
Background technology
Triangle circle all-welded ball valve is a kind of widely used valve, the pipeline of natural gas line transmission and urban heat supplying
On.Common all-welded ball valve structure type mainly has：It is floating type, fixed etc., wherein the most with fixed all-welded ball valve
It is common.Common fixed full solder sphere sealing material using reinforced TFE and PPL, reinforced TFE and
The resilience of PPL is poor, and after valve often opens and closes, the leakproofness of valve cannot be protected.It developed again later a kind of new
Material fluorubber, can be with the sealing performance and service life of effective guarantee valve.But this material hardness is not high, it is inlayed
The technique on valve seat is embedded into just at problem, the most commonly used is " tabletting types ", and normally sealing ring is put in processing exactly on valve seat
Behind position, then one " technology groove " is increased above, then add a piece of " tabletting " in " technology groove ", processing technology is quite multiple
Miscellaneous, repair is also inconvenient.
Invention content
The purpose of this utility model is against the above deficiency, to provide a kind of all-welded ball valve with triangle circle screw thread valve seat.
Realizing the technical solution of the utility model aim is：A kind of all-welded ball valve with triangle circle screw thread valve seat, including
Valve body, valve deck, sphere, valve component and valve rod, the valve body welded bonnet (WB), sphere setting is in valve inner and key
The valve rod for the side of connecting, valve deck inside are provided with valve component；The valve component includes valve seat and disc holder, institute
The valve seat threaded engagement disc holder stated.
Preferably, triangular groove is provided on the valve seat, triangular groove is located at valve seat threaded engagement disc holder, described
Triangular groove upper valve be provided with triangle circle.
Preferably, radially installed holding screw on the disc holder.
Preferably, it is also provided with spring eye on the disc holder, spring is mounted in hole.
The utility model has the characteristics that economical, reliable, has good practical value, can be generated after popularization and application good
Economic benefit.
