Description
Technical field
The present invention relates to industrial valve field, particularly one wets chlorine special valve.
Background technique
Wet chlorine is the medium that in chlorine industry, corrosivity is the strongest, the valve be used under normal circumstances on wet chlorine adopts common chlorine cutoff valve or common bellows stop valve, it is applied in wet chlorine pipeline exists following defect: (valve body adopts 316 or 316L to the material of common chlorine cutoff valve usually, flap and valve seat built-up welding+Stellite Si Taili) highly corrosive of wet chlorine cannot be stopped at all, substantially will by valve member heavy corrosion within 30 days, cause losing efficacy, there is severe compromise, change will bring the cost of great number if frequent; In the production and conveying of chlorine medium, common chlorine valve uses filler to realize sealing substantially, and in opening and closing frequently, valve rod and filler produce radial and axial two kinds of frictions superposed.The as easy as rolling off a log wearing and tearing of filler, as non-Timeliness coverage and replacing filler, probably leaking of pipeline internal medium, causes serious accident, part has adopted on the chlorine pipeline of common bellows stop valve, although achieve double seal, improve sealability, but the directly core component material of contact medium, what especially bellows was selected is all metal material, such as Hastelloy and monel metal etc., still corrosivity cannot be stopped, on the wet chlorine pipeline of highly corrosive, be easy to the situation occurring ripple tube failure, no matter interior leakage or leak, consequence all will be very serious, light then cause the economic loss of enterprise, severe patient will jeopardize the life safety of practitioner, even social event may be caused.
Summary of the invention
For deficiency of the prior art, the invention provides a kind of wet chlorine special valve, deficiency of the prior art can well be overcome.
Wet chlorine special valve, comprises valve body, valve body is provided with valve gap and inner valve stem, inner valve stem is provided with bellows, filler and flap, is provided with pressing plate above filler, and pressing plate is connected and fixed by nut and hex head bolt and valve gap, valve interior wall, inner valve stem, flap and filler carry out omnibearing stereo formula lining fluorine F46, inner valve stem, bellows, flap and filler are integral type assembly, bellows adopts the machine shaping of F46 material, bellows upper end uses expanded letter design, bellows is provided with embedded reinforced sheet, this reinforced sheet adopts 65Mn material, external shape is circular, fit with bellows, interior shape gear shape, fit with inner valve stem, bellows outer rim is placed in groove that valve gap and valve body contact end face design, through nut and stud bolt by valve body, valve gap is connected with bellows and is locked, inner valve stem upper end is connected with outer valve rod by contiguous block and connecting screw, outer valve rod is provided with handwheel, is provided with hand wheel nut above handwheel, is provided with valve mother below handwheel, valve mother is provided with limited ring and caging bolt, valve body is also provided with indicator of opening.
the beneficial effect of wet chlorine special valve provided by the inventionbe through research and development to improve, valve body and the valve member that can touch medium have been carried out omnibearing stereo formula lining F46, F46 is the copolymer perfluoroethylene-propylene (FEP) of tetrafluoroethylene and hexafluoropropene, wherein the content of hexafluoropropene is 15%, and the content of tetrafluoroethylene is 85%, is the material modified of teflon, F46 has excellent chemical stability, all can not be corroded with during other chemical contact, the corrosivity that wet chlorine brings can be stopped completely, guarantee the use safety of valve on pipeline, on the basis of the double sealing structure form that the bellows had at Bellows valve is filled, unitary design is carried out to key core position valve rod, flap, sealing alms bowl, filler and most crucial bellows and omnibearing stereo formula lining fluorine, become the high security special valve that multiple functions such as having sealing, corrosion protection, raising working life gathers the whole body, core black box bellows, directly adopt the once-through of F46 material precision machining, for DN25 bore valve, its thickness can reach 1.8mm, utilize the fatigue resistance that material is excellent, realize on-off times and reach more than 1.5 ten thousand times, consider that the anti-pressure ability of New corrugated pipe under high pressure is not enough, easy distortion, the embedded bellows reinforced sheet of special R & D design, this reinforced sheet adopts 65Mn material, external shape is circular, fit with bellows, interior shape gear shape, fit with valve rod, realize bellows under a certain pressure indeformable, reinforced sheet is embedded in each ripple, thus improve the anti-pressure ability of New Type Material bellows, maximum pressure can reach PN8.0, higher than JB/T9092 test and inspection standard, bellows both realized sealing function, protect valve rod again, material is again anticorrosive material simultaneously, achieve revolutionary breakthrough, thoroughly improve Safety performance and the shelf life of valve, characteristic for medium has set up indicator of opening especially, change traditional stop valve only according to the primitive operation method of carrying out experience adjustment.
