Description
Technical field
The present invention relates to industrial valve field, more particularly to a kind of wet chlorine special service valve.
Background technology
Wet chlorine is the medium that corrosivity is most strong in chlorine industry, uses the valve on wet chlorine under normal circumstances using common
Chlorine cutoff valve or common bellows stop valve, it is applied has following defect in wet chlorine pipeline：Common chlorine is cut
The only material of valve（Valve body generally use 316 or 316L, flap and valve seat built-up welding+Stellite Si Taili）It can not stop at all
The highly corrosive of wet chlorine, valve member heavy corrosion will be caused to fail, it is hidden to there is severe safety substantially within 30 days
Suffer from, if the cost of great number will be brought by frequently changing；In the production and conveying of chlorine medium, common chlorine valve is substantially
Sealing is realized using filler, in frequently opening and closing, what radial and axial two kinds of valve rod and filler generation was superimposed rubs
Wipe.Filler is easy to abrasion, does not find in time with changing filler such as, pipeline internal medium is likely to leak, and causes major accident；
Part using on the chlorine pipeline of common bellows stop valve, although realizing dual-seal, improves sealing property,
It is the core component material of direct contact medium, what especially bellows was selected is all metal material, such as Hastelloy and illiteracy
Alloy etc. like this, it still can not stop corrosivity, on the wet chlorine pipeline of highly corrosive, it is easy to the feelings of ripple tube failure occur
Condition, no matter interior leakage or leak, consequence all will be very serious, gently then cause the economic loss of enterprise, and severe patient will jeopardize working
The life security of personnel, in some instances it may even be possible to cause social event.
The content of the invention
For deficiency of the prior art, the present invention provides a kind of wet chlorine special service valve, can be very good to overcome prior art
In deficiency.
Wet chlorine special service valve, including valve body, bonnet and inner valve stem are provided with valve body, bellows is provided with inner valve stem, is filled out
Material and flap, filler top are provided with pressing plate, and pressing plate is connected by nut and hex bolts with bonnet；It is valve interior wall, interior
Valve rod, flap and filler carry out omnibearing stereo formula Fluorine-lined F46, and inner valve stem, bellows, flap and filler are integral type component,
Bellows uses F46 material machine-shapings, and bellows upper end is designed using expanded letter, and embedded reinforced sheet is provided with bellows,
The reinforced sheet uses 65Mn materials, and outer shape is circular, is bonded, interior shape gear-like, is bonded with inner valve stem, ripple with bellows
Line pipe outer rim is placed in the groove designed on bonnet and valve body contact end face, through nut and stud by valve body, bonnet and ripple
The connection of line pipe is locked；Inner valve stem upper end is connected with outer valve rod by contiguous block and connecting screw, is set on outer valve rod
There is handwheel, hand wheel nut is provided with above handwheel, valve mother is provided with below handwheel, restraining position ring block and spacing spiral shell are set on valve mother
Bolt；Indicator of opening is additionally provided with valve body.
The beneficial effect of wet chlorine special service valve provided by the invention is improved by research and development, by valve body and can touch medium
Valve member has carried out omnibearing stereo formula lining F46, and F46 is the copolymer perfluoroethylene-propylene of tetrafluoroethene and hexafluoropropene
（FEP）, the wherein content of hexafluoropropene is 15%, and the content of tetrafluoroethene is 85%, is the material modified of polytetrafluoroethylene (PTFE), F46
It with excellent chemical stability, will not be corroded when being contacted with other chemicals, the corrosion that wet chlorine is brought can be stopped completely
Property, it is ensured that valve is safe to use on pipeline；In the filled double sealing structure form of the bellows that Bellows valve has
On the basis of, unitary design is carried out simultaneously to key core position valve rod, flap, sealing alms bowl, filler and most crucial bellows
Omnibearing stereo formula Fluorine-lined, become the Gao An for gathering the whole body with multiple functions such as sealing, anticorrosion, raising service lifes
Full property special valve；Core seal assembly bellows, F46 material Precision Machining one-shot formings are directly used, with DN25 bore valves
Exemplified by door, its thickness can reach 1.8mm, using the excellent fatigue resistance of material, realize on-off times reach 1.5 ten thousand times with
On, it is contemplated that the anti-pressure ability deficiency of New corrugated pipe under high pressure, it is easily deformed, the embedded bellows of special R ＆ D design
Reinforced sheet, the reinforced sheet use 65Mn materials, and outer shape is circular, is bonded with bellows, interior shape gear-like, is pasted with valve rod
Close, realize that bellows is indeformable under a certain pressure, reinforced sheet is embedded into each ripple, so as to improve New Type Material ripple
The anti-pressure ability of line pipe, maximum pressure can reach PN8.0, both realize close higher than JB/T9092 experiments and test stone, bellows
Function is sealed, protects valve rod again, while material is anticorrosive material again, realizes revolutionary breakthrough, thoroughly improves the peace of valve
Full performance and shelf life, indicator of opening is especially additionally arranged for the characteristic of medium, changes traditional stop valve only according to entering to pass through
Test the primitive operation method of regulation.
