Description
Technical field
The present invention relates to a kind of valve arrangement of controlling plumbing fixtures gas medium, harmful, inflammable, explosive particularly to poisonous, the control of radioactive air cuts off.Be applicable to metallurgy, electric power, chemical industry, municipal administration, environmental protection, industries such as combustion gas.
Background technique
At present, control both at home and abroad cuts off pipeline gas, and particularly control cuts off valve arrangement poisonous, harmful, inflammable, explosive, the radioactive air medium, and its technology also rests on the eighties in last century so far.Though some patented technology has been implemented local improvement for many years, there is not the change of essence because of the external and internal compositions design.Have poor performance, parameter is low, and operability is poor, poor stability, and befouling environment, maintenance difficult, nonstandard manufacturing, manufacturability is poor, cannot say for sure to demonstrate,prove quality of product, engineering cost, manufacture cost is high.The valve that cuts off gas like closed control is technological, sees number of patent application, the valve plate Double roll system (200710061658.3) of glasses valve; High-performance push-pull valve (200620127908.X); A kind of frame type glasses valve (200720131170.9), above-mentioned patented technology, main body are the framework case structure; Valve plate is dull and stereotyped pressure-bearing design, opens and closes switching mechanism and hangs the horizontal mode that moves horizontally of inserting of straight line for floating.This technical pattern volume is big, and weight is big, and cross-section area is big, and it is big to take the pipeline space position; Bearing capacity is low, and main body rigidity is little, and intensity is low, valve plate centre-of gravity shift; Drive stressed irregularly, walking is unstable, is prone to produce jam, and stroke is long; Open and close slowly, spacing easy to failure, and receive the piping erection position limit, be difficult for optimizing the process pipelines design.Owing to exist above-mentioned defective not enough, closed control isolating valve gate technique is used be restricted, be difficult to adapt to the demand of modern industry development.Open type isolating valve technology is seen number of patent application, and valve plate open type blank-plate valve (200620071452.X) floats; A kind of vertical glasses valve (200820215512.X), electric pushrod Flap valve (201020221082.X) is when opening and closing conversion or sealing pair when taking place to leak; The pipeline gas medium directly leaks to the external world, is prone to cause the accident poor stability; Befouling environment, accident constantly takes place for many years.Consult Hubei Province safety supervision pipe one [2008] No. 269, about the circular of Echeng iron and steel Co., Ltd of Wuhan Iron and Steel Plant group " 1018 " gas poisoning.Safety supervision house steward four [2009] No. 182, the circular of two smelter gas poisonings is in the near future closed in national security supervision general bureau.
Summary of the invention
Use present situation in order to overcome the defective deficiency of existing technology, to change.The object of the invention provides a kind of safety and environmental protection, high-performance, high parameter, low cost; Operability is reliable, and the particularly control of optimized Structure Design cuts off poisonous, and is harmful, inflammable; The valve arrangement explosive, that radioactive air matter is situated between is to adapt to the demand of modern industry development.
The technological scheme that the present invention solves its technical problem employing is:
For a change existing closed isolating valve technology, valve body is the framework case structure, and valve plate is that the volume that causes of dull and stereotyped bearing structure is big, and bearing capacity is low, and stiffness is little, and intensity is low, and it is big to take the pipeline space position, nonstandard manufacturing, manufacturability is poor, maintenance difficult.And open and close switching mechanism, and float and hang the valve plate centre-of gravity shift that the horizontal slotting mode of moving horizontally of straight line causes, drive stressed irregular; Produce jam, walking is unstable, and stroke is long; Open and close slowly, spacing easy to failure, and receive the restriction of piping erection position; Be difficult for optimizing the process pipelines layout, defectives such as cost height are not enough.Eliminate poor stability, the open type isolating valve technology of befouling environment.The present invention has adopted by the double spherical valve plate, along spherical track, and revolution synchronously; The independent double spherical valve plate switching mechanism that floats is with interlocking balancer structure, with the ball-type valve body; With displacement apparatus, with drainage device, with cooling system; With the flexible tight mechanism of spherical valve plate holder of multiple spot bit synchronization,, constitute the valve arrangement that totally enclosed type control cuts off gas medium with bleeding device with blowing cleaner.
The invention has the beneficial effects as follows:
1. totally enclosed type double spherical interlocking isolating valve design optimally, have multi-functional, safety and environmental protection, high-performance; Compact structure, it is little to account for the pipeline space position, easy to maintenance; Do not receive the restriction of piping erection position, can install and use, optimize advantages such as process pipelines design in the pipeline any angular position.
2. optimally adopt the design of double spherical valve plate switching mechanism, the double spherical valve plate with rigidity upset driving is stressed evenly, opens and closes steadily, and stroke is short, and keying is fast, the reliable advantage of operability.
3. optimally adopt the design of arc bearing structure, with existing technology contrast, the valve volume reduces 30%～40%, and weight reduces 30%～40%, and cross-section area reduces 40%～50%, and cost of production reduces by 30%～40%.Main body is the bearing structure of spherical valve body and ball-type valve plate, has the bearing capacity height, and the main body stiffness is big, the high advantage of intensity.
4. the rotary structure manufacturing process has good manufacturability, is prone to realize standardization, and automated manufacturing guarantees quality of product.
5. optimally adopt ball-type sealing pair design of Sealing Structure, have the good airproof performance advantage.
6. optimally interlocking balancer structure design is implemented in the interlocking uniform voltage function of valve body, the batch production manufacturing, and mode is installed, and reduces occupied ground, practices thrift cost.
7. optimally design of Cooling System realizes the cooling to whole sealing pairs, has improved serviceability temperature, has prolonged the life-span.
