Description
Technical field
The utility model relates to a kind of sealing configuration, refers in particular to the mechanical seal that is applied on reactor.
Background technique
When the related sealing medium of reaction vesselseals is gas, because the permeability of gas is strong, the poor lubrication of seal face, therefore require the pressure between seal face larger, so compare the operating conditions of its seal face with the common mechanical sealing harsher, and be in dry condition, end wear is larger, so vesselseals must consider that fully it is lubricated and cooling; And when having Korrosionsmedium or poisonous medium in reactor, vesselseals is more required high reliability, prevent that Korrosionsmedium from causing the leakage of toxic gas or Korrosionsmedium to the seal arrangement corrosion; Also to prevent from increasing because of complex structure, fault point the leakage of poisonous or the Korrosionsmedium of causing that break down.
the structure of vesselseals commonly used is that the subdivision snap ring is connected in rotating shaft through O type circle, the bellows rotating ring is connected on spring seat and is sleeved in rotating shaft, between spring seat and subdivision snap ring, spring is installed, the bellows rotating ring presses to stationary ring and forms end face seal under the effect of spring, stationary ring is sleeved in rotating shaft and by food tray and is fitted on stationary seat, filling oiling agent in food tray is lubricated seal face and seal face is transmitted out because of the heat that friction produces, food tray and stationary seat bolton, seal by O type circle between stationary ring and stationary seat, stationary seat is fixedly connected on an end of enamel water jacket, be pressed with seal ring between stationary seat and enamel water jacket, also has packing seal between enamel water jacket and rotating shaft, the other end of enamel water jacket is arranged on reactor by sealing gasket.
The mechanical seal device of said structure exists following deficiency, the one, because food tray is arranged on stationary seat, and stationary seat need to be connected with the enamel water jacket by bolt, Gu food tray can only be within the connecting bolt scope of stationary seat and enamel water jacket, its diameter can't be done greatly, the Sheng oil mass is limited, and lubricated and heat-conducting property is restricted; The 2nd, stationary ring is installed and locates by a series of parts such as stationary seat, seal ring, stuffing box gland, enamel water jackets, the influence factor of its installation precision is many, make the seal face between stationary ring and rotating ring well not fit, sealing effect can not be guaranteed, so many parts also can cause the complexity of structure to bring the increase of fault point simultaneously, and the reliability of seal arrangement is not high.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of reaction mechanical sealing device for cauldron, improve on lubricated and heat-conducting property, while designs simplification, the seal face installation precision between dynamic and static ring can better be guaranteed, to improve sealing and reliability.
for solving the problems of the technologies described above, a kind of reaction mechanical sealing device for cauldron of the present utility model, comprise stationary ring, the bellows rotating ring of fitting with the stationary ring end face that is connected to bellows one end, the locking ring that the described bellows the other end arranges, the seal ring of installing on the locking ring endoporus, be set with the spring seat of bellows rotating ring, the spring that arranges between spring seat and locking ring, food tray, the enamel water jacket, and be arranged on stuffing box gland on enamel water jacket upper end hole, described stationary ring is arranged in the step hole of food tray bottom side, food tray and enamel water jacket are bolted connection, the lower end surface of stationary ring and the end face of stuffing box gland are fitted.
after adopting said structure, because the stuffing box gland upper-end surface that stationary ring and enamel water jacket upper end are installed directly compresses applying, left out stationary seat, a series of centre parts such as the O type circle sealing between stationary ring and stationary seat, greatly reduced the stationary ring installation precision error that the existence due to centre part brings, guaranteed the end face applying effect between stationary ring and rotating ring, sealing effect is guaranteed, the structure of device is simplified, reduce the fault point, improved the reliability of this mechanical seal device, in addition, simplification due to structure, make the volume of food tray be become large, the Sheng oil mass increases, strengthened lubricated, cooling and sealing effect.
Description of drawings
Below in conjunction with the drawings and specific embodiments, a kind of reaction mechanical sealing device for cauldron of the utility model is described in further detail.
Fig. 1 is a kind of structural representation that reacts a kind of specific embodiments of mechanical sealing device for cauldron of the utility model;
In figure: filler, 11-enamel water jacket, 12-sealing gasket in 1-seal ring, 2-lock bolt, 3-locking ring, 4-spring pin, 5-spring seat, 6-bellows rotating ring, 7-food tray, 8-stationary ring, 9-stuffing box gland, 10-
In reaction mechanical sealing device for cauldron shown in Figure 1, locking ring 3 is split type structure, is fastened in rotating shaft by the bellows end sealing of lock bolt 2 with bellows rotating ring 6, and locking ring also is equipped with seal ring 1 to guarantee sealing effect in 3 holes; The seal ring end of bellows rotating ring 6 is sleeved in spring seat 5, and four springs 6 are installed between spring seat 5 and locking ring 3, and under the effect of this spring 6, the bellows rotating ring 6 that is arranged on spring seat 5 fits tightly with stationary ring 8 end faces, forms motive sealing; Stationary ring 8 is that drive fit is arranged in the step hole of food tray 7 bottom sides, guarantees that the lubricant oil in food tray must not seepage; Food tray 7 is bolted to connection on the upper flanges of enamel water jacket 11, stationary ring 8 and the stuffing box gland 9 that is arranged in enamel water jacket 11 upper end holes are fitted tightly, stuffing box gland 9 and enamel water jacket upper-end surface are fitted tightly, stuffing box gland 9 is the teflon material, have suitable elasticity and good decay resistance, can guarantee not produce seepage between the faying surface of itself and stationary ring 8 and enamel water jacket 11; The lower end flange of enamel water jacket 11 is connected with reactor, and its end face is equipped with sealing gasket 12, makes between enamel water jacket 11 and reactor and forms static seal, to guarantee not produce seepage between enamel water jacket 11 and reactor; Middle filler 10 also is installed in enamel water jacket 11 endoporus, can and rotating shaft between play seal action, to reduce the load of end face seal between dynamic and static ring.
Above-mentionedly only enumerated a kind of preferred implementation of the present utility model, but the utility model is not limited to this, in the situation that without prejudice to the utility model basic principle, can also do many improvement and conversion.As: as described in can be not only that drive fit is installed between stationary ring 8 and food tray 7, also can set up seal ring between food tray 7 and stationary ring 8 and form static seal; Equally, also can set up seal ring between stuffing box gland 9 and stationary ring 8 and enamel water jacket 11 and form static seal, and so on, so long as improvement and the conversion done based on the utility model basic principle all should be considered as falling into protection domain of the present utility model.
