Description
Technical field
The utility model relates to a kind of novel stopcock in the petrochemical industry recovery technology of sulfur control system, i.e. high temperature one balanced hoisting formula chuck stopcock.Recovery technology of sulfur process gas, liquid-state sulfur are carried out switch control.
Background technique
At present; The switch valve of sulfur recovery facility system process control adopts soft seal chuck ball valve or chuck butterfly valve, and its structure is; Chuck is wrapped in outside the valve housing; Through 160 ℃-280 ℃ insulation steam, reach circulation valve medium temperature and surpass its freezing point temperature, prevent valve control system medium crystallization and freezing.In addition, one of valve closing member is a soft seal fluoroplastic material, and fluoroplastic are corrosion swelling or aging under long-term working temperature, and mechanical property descends, and causes the valve seal inefficacy maybe can't open and close, and working life is short, often occurs keeping in repair because of valve invalidation stops production.
Existing domestic lifting type stopcock structure: adopt cock body to be connected in the valve body cavity through T type structure with valve rod; The cock body straight line motion is the straight line elevating movement in the body cavity conical surface; Cock body is impacted by the import medium, and the cock body sealing cone and the valve seal conical surface partly fit tightly, and causes sealing surface position local friction; Catching phenomenon possibly occur when serious, directly scratch sealing surface.If adopt other type valves to solve the problem of existence, like hard seal ball valve, keying moment is big, and manufacture cost is high; Adopt gate valve keying moment big, be prone to the flashboard stuck phenomenon because of the working temperature reason simultaneously, and installing space is big.Adopt the stop valve flow resistance coefficient big, energy consumption is high, and it is big to open and close moment simultaneously, defectives such as sealing reliability difference.
The model utility content
The utility model purpose is a kind of hard sealed jacket stopcock of one balanced hoisting formula structure that high temperature sulphur technology reclaiming system technology controlling and process requires, i.e. high temperature one balanced hoisting formula chuck stopcock of adapting to of development.Reach valve seal and do not receive the work condition environment Influence of Temperature, during valve opening and closing, sealing surface rotation " zero " friction, elevating movement sealing surface keying wearing and tearing are evenly, sealability is reliable and stable and prolong the control valve purpose in working life.For providing function, the sulfur recovery facility system guarantees.The purpose of the utility model is to satisfy recovery technology of sulfur control requirement, solves tratitional technology and selects control valve short problem in working life for use, minimizing system cause because of control valve lost efficacy the stopping production purpose of maintenance.
The technological scheme of the utility model is:
High temperature one balanced hoisting formula chuck stopcock connects driven unit by fixed valve body mechanism through Stuffing box and forms, and it is characterized in that: fixed valve body mechanism connects support by valve component through the bolt joint and forms; Driven unit is formed through the one balanced type cock body that the connection of loose joint bindiny mechanism has rotatable handle by having the actuate valve stem of going up and down to drive handwheel.
Described high temperature one balanced hoisting formula chuck stopcock; It is characterized in that: in valve component; It about it fluid medium channel; On the fixing bottom in lower central line place the bottom axis hole is arranged, the fixing Stuffing box centerline in valve component middle part connects axle on the cock body of one balanced type cock body, the support central upper portion line place on the valve component connect can about, rotating actuate valve stem; Its upper, middle and lower center line is corresponding.
Described high temperature one balanced hoisting formula chuck stopcock is characterized in that: rotatable, the straight-line one balanced type of lifting cock body upper end cylinder boss is hung through loose joint bindiny mechanism and is connected on the actuate valve stem boss of actuate valve stem lower end.
Described high temperature one balanced hoisting formula chuck stopcock; It is characterized in that: loose joint bindiny mechanism is by splitting on the coupling collar Fixing shrink ring and axle is formed with check ring, splits cylinder boss and actuate valve stem lower end actuate valve stem boss on the hinged or butt joint one balanced type cock body of coupling collar inner chamber removable.
Described high temperature one balanced hoisting formula chuck stopcock is characterized in that: axle is gone up fixedly rotatable handle on the cock body of rotatable, up and down one balanced type cock body; The circular cone cock body of one balanced type cock body is the circular cone cylinder, and its outer surface has the cock body sealing surface that matches with valve body sealing surface, and it radially has the cock body runner through flowing medium, and this cock body runner communicates with cock body equalizing orifice on the one balanced type cock body; The lower end cock body lower shaft of one balanced type cock body is arranged in bottom bottom axis hole and locatees.
The advantage and the effect of the utility model are following: when at first the main innovate point of the utility model was valve opening and closing, first straight line motion broke away from before integral type balanced type cock body sealing surface and the valve body sealing surface rotation, " zero " friction between sealing surface during rotation.Secondly, one balanced type cock body structure, this cock body remains the relative fixed position in valve body; Sealing does not receive pressure medium and influence of temperature change; Seal pressure remains evenly constantly between cock body and valve body, and the long-term high frequency time of sealing surface opens and closes wearing and tearing evenly, and sealing is reliable.It is short working life that the enforcement of the utility model has fundamentally solved the recovery technology of sulfur system control valve, stops production to change the problem of maintenance, reduces the parking maintenance loss of system, guarantees the reliable operation of system.The hard sealed jacket stopcock design of one balanced hoisting formula structure overcomes the shortcoming of General valve, and is through long-term operating mode operation, safe and reliable.Also be suitable for industrialized production.
