Description
Technical field
The present invention relates to a kind of high pressure filling selfsealings balance swaged forging formula switching ball, be the high-pressure ball valve that can be widely used in oil refining industry, belong to instrument control field.
Background technique
Oil is as a kind of non-renewable resources, and the supply crisis faced produces increasing impact to socioeconomic development, and the impact of this lasting aggravation constantly penetrates into everyone life.Update method and technique, raising are one of major programme of this problem of reply at present to the utilization ratio of petroleum resources, and the crude oil refinery being in leading position in whole Petroleum Industry then seems particularly crucial.Service cycle from processing method to processing device, Oil Refining Industry is just being forced to experiencing huge change, and more advanced meticulous refinery technology improves output and environmental protection standard, but also to high temperature resistant, the high pressure ability of device with propose rigors working life.Above-mentioned change adds that the appearance of low-sulphur fuel standard, the processing request of low grade crude oil and more bottoms need conversion, makes it possible to resistance to 2500LB and sharply rises with the high pressure cut-off ball valve demand of upward pressure.
First crude oil need after being transported to oil refinery to carry out desalting processing through desalter, then enter atmospheric distillation tower and carry out separated, enter corresponding downstream purifier respectively from the light oil of the atmospheric distillation tower different molecular weight such as naphtha, gasoline, diesel oil out and heavy oil and carry out process of refinement, after a series of process such as continuous catalytic reforming, fixed bed hydrogenation process, fixed bed hydrogenation cracking, bubbling bed hydrocrack, finally become the end products such as motor petrol, diesel oil, aviation kerosine, pitch.In whole purifier, almost most critical process position all needs to install 2500LB with the high pressure cut-off ball valve of upward pressure, comparatively typical in fixed bed hydrogenation process, fixed bed hydrogenation cracking, the toolings such as bubbling bed hydrocrack, actual working pressure reaches the high score gas of more than 20.5MPa or cold high score gas and oil needs featuring rigid cutting-off, any interior leakage or the phenomenon that leaks outside can not be had, and valve must ensure can open at any time when being in closed condition for a long time, this is all to the high-voltage resistance capability of valve, sealability, Reliability of Microprocessor, propose very harsh requirement working life.
In current prior art, valve rod is connected with the flat tenon of valve ball by cutting ball valve for high pressure operating mode usually, the bottom of ball be provided with driven shaft for supporting sephere, reduce the side-play amount that pressure medium causes, valve rod position adopts the packing seal structure that can repeatedly compress, and valve seat location then adopts O type circle to seal.If the cutting ball valve of said structure is used in 1500LB and generally there will not be obvious problem in the ordinary high pressure operating mode of downforce, but under the working condition pressure of more than 2500LB, but must bear following risk: first valve ball can be pushed to side by the pressure medium of huge (>=20MPa), valve ball is caused to depart from sealing surface of seat, leakage rate increases gradually, more seriously because valve ball skew causes valve rod action bite, valve is difficult to normal switch, causes valve rod to twist off under extreme case; Secondly the O type circle sealing configuration adopted between valve seat and valve body cannot bear the working pressure of 2500LB, and the high score gas of upstream or cold high score gas and oil enter downstream line by valve seat and valve body clearance leakage and produce Accident due to quality; Finally because the long-term work under the high pressure of 2500LB of common fillers sealing configuration is very easily aging, cause valve rod position sealing failure of fillers, ducted high flammability medium leaks outside in air via stuffing box.It is a breakneck thing all the time that oil refinery catches fire, but if fire spreading is to being equipped with the air-distillation king-tower of substantial oil and relevant side stripper, fire will develop into rapidly the disaster that cannot be estimated its consequence.
Summary of the invention
