Description
Technical field
This utility model relates to automatic control technology field, particularly relates to the sealing of a kind of controllable flow rate, temperature, pressure
Performance is good, reliability is high, long-lived High Temperature High Pressure special regulation valve.
Background technology
In industrial automatic control, often need to use regulation valve to control flow, temperature, pressure.Existing regulation valve,
As shown in Figure 1, it includes valve body (01), valve gap (02), valve seat (03), spool (04), sleeve (05), balanced seal to its structure
Ring (06), valve rod (07), filler group (08), gland (09), dust ring (010).This class formation has the disadvantage in that
1, use sealing at two at valve seat (03) and seal spool, be metal sealing at one, be soft seal at another, due to
Soft seal selects plastic to seal, and its poor flexibility, not resistance to high temperature, maximum operation (service) temperature is 200 degree；
2, spool (04) inwall is the thinnest, when running into high temperature, and the easy high temperature deformation of flatulence of heat type principle, and easy and bottom valve seat metal
Produce leakage, easy and sleeve (05) locking at sealing, affect serviceability；
3, balanced seal ring (06) material functional plastics, does not overcomes high temperature and granule operating mode equally；
4, after valve rod (07) and spool (04) connect screw thread, carrying out Type of Welding, it is impossible to change online, plant maintenance is number
Tired；
5, filler group (08) combines short, and sealed relative distance shortens relatively, and spool farther out, is not had by its distance spool
Guide effect；
6, gland (09) and valve gap (02) use threaded form, easily kill, do not have secondary under worst hot case
Compress sealing function.
In a word, for the regulation valve that current ambient temperature is conventional, due to standardization, modularity is not enough, and its use temperature is low, pressure
Difference is low；Cannot solve under the operating mode that temperature is high plus existing regulation valve, its sealing effectiveness is poor, pressure reduction is low, frictional force is big asks
Topic, and its ambient adaptability is strong, reliability is low, be not durable.
To sum up, be presently required one can high temperature high voltage resistant, ambient adaptability is strong, good seal performance, reliability are high, prolonged resistance to
Regulation valve, to meet productive life demand.
