Background technique:
The valve of valve working temperature t > 450 DEG C is generally known as high temperature valve.In the production process of polyether sulphone, gather virtue
For ether sulfone (PSF) material itself because melt viscosity is big, processing temperature is high, causes to require harshness to process equipment and technique, fluid is defeated
It send in system, valve is indispensable control unit, mainly has the function such as adjusting, water conservancy diversion, counterflow-preventing, cut-off, shunting
Can, valve is very widely used in industry and civil field.High temperature valve is a more common seed type in valve, it
Specific performance it is as follows: quenching property is preferable, can carry out deep-hardening；Weldability is good；There is good absorbability to impact
Can, it is difficult to damage it by violence；It is less to temper brittleness tendency etc..The type of high temperature valve is relatively more, than
More typical has high temperature butterfly valve, high-temperature ball valve, high-temperature filter, high temperature cut-off valve etc..High temperature valve internals are usually because of temperature
It is excessively high, there is the case where anneal of material or softening, such case easily causes trim galled spots.To influence valve
Service life.
Summary of the invention:
The purpose of the present invention is provide a kind of polyether sulphone production high-temperature sealing valve, sealing performance in view of the above problems
It is good, damage of the high temperature to spool can be effectively avoided, it is stable and reliable in work.
