When the utility model is used, the material selection RPTFE of valve seat 5, RPTFE is by suspension polytetrafluoroethylene resin through mould
Pressure sizing, is sintered, and RPTFE has most excellent chemical corrosion resistance and dielectric properties in known plastic, can be -250
It is used in DEG C of -+250 DEG C temperature ranges, RPTFE has minimum coefficient of friction, best corrosion resistance, warp in known plastic
Crossing repeatedly test proves, the valve seat 5 that 20% glass fibre filling PTFE material is done, because material hardness is big, under the effect of certain pretightning force
It is hardly formed band between valve seat 5 and T-type ball valve 6, sealing function cannot be played, when pretightning force increase, valve seat 5 and T-type ball
Frictional force between valve 6 increases, and the torsion that the external world provides is not enough to turning T-type ball valve, cause valve cannot normally open and close or
Open and close not tight, leakage in formation；10% glass fibre filling PTFE and pure PTFE mechanical performance are almost the same, do not have as 5 performance of valve seat
It is obviously improved；The valve seat 5 of 13%~17% glass fibre filling PTFE material, by tests up to ten thousand time, mechanical performance and chemically
Environment of the long-term work at 150 DEG C can be fully met.Therefore, when the substance of high temperature, acidity, alkalinity etc. flows through in the utility model
When related triple valve, valve seat 5 can effectively prevent to cause valve seat 5 to be plastically deformed because temperature is too high or acid-base property is too strong and make greatly
At leakage or valve be not closed completely the problem of, substantially improve 5 sealing effect of valve seat.
Interface valve deck and bushing are made of one in the utility model, effectively prevent medium from interface valve deck and bushing it
Between slot leakage tradition three-way ball valve interface valve deck and bushing be separation, this structure both increases machining and assembly
Difficulty, and valve leak risk is increased, meanwhile, because the interface valve deck and bushing of traditional three-way ball valve are two components, filling
With needing to install a sealing ring in the process, between both parts again, prevent the intracorporal medium of valve between both parts
It lets out.
Based on above-mentioned, the utility model was by both having reduced interface valve deck for interface valve deck and the integral part of bushing design
With difficulty of the bushing in machining and assembly, and the sealing effect of its own is significantly improved, then contains glass by selecting
Material of the ptfe composite of glass fiber as valve seat is prevented because temperature is too high, too strong etc. reasons of acid-base property,
The problem of leakage caused by valve seat plastic deformation is big or valve are not closed completely, improves the sealing effect of valve seat, improves valve
Itself service life.
Therefore, embodiment disclosed above, in all respects are merely illustrative, not the only.It is all
Change within the scope of the invention or equivalents of the invention is included in the utility model.
