Description
Technical field
The utility model relates to the flue gas diffusion valve using in a kind of production of carbon black, particularly a kind of carbon black smoke diffusion valve.
Background technique
The tail gas of production of carbon black has high moist (containing water vapor approximately 35～40%), the high dew point feature of (being about 180 degree left and right), and the emergency cut-off that carbon black smoke diffusion valve will diffuse under displacement mixed gas and the accident condition at production initial stage diffuses, it is the critical component of production of carbon black safe operation.The diffusion valve using at present as shown in Figure 2; principle is to rely on gravity, and valve gap is realized the switch of valve body under the acting in conjunction of pivoted arm, support arm, hinge, in the time that valve body internal pressure is greater than valve gap deadweight; pressure can back down valve gap voluntarily and open, the normal safe operation of protective system.After pressure reduces, valve gap can fall voluntarily under the effect of gravity, with valve seal.But along with the prolongation of service time, because of corrosion and crock, make the rough surface of sealing contact surface, gap is strengthened, and forms Leakage Gas, and the flue-gas temperature dew point dewfall of leakage has increased the weight of again the corrosion of sealing surface, cause maintenance maintenance amount large, and effect is bad.Because the easy burn into switch sealing that carbon black tail gas diffusion valve occurs is poor, cause the carbon black tail gas leakage problem of appearance, bring great hidden danger to safety in production, be badly in need of diffusion valve to carry out technological improvement.
Model utility content
The purpose of this utility model is to provide a kind of carbon black smoke diffusion valve prior art deficiency, simple in structure, easy to use, to increase mechanical strength and decay resistance that overcomes.
A kind of carbon black smoke diffusion valve, comprise valve body, valve gap, hold-down mechanism, valve gap be shaped as funnel form, on the top board of valve body, offer leakage port, hold-down mechanism is fixedly connected with the upper-end surface of valve gap, valve gap and leakage port form and are sealed and matched, described leakage port be shaped as the toroidal of inwardly opening, valve body is positioned at the top board and valve gap formation linear sealing of leakage port periphery.
Described hold-down mechanism is cylinder, sets up fixed support in the upper end of valve body, and the fixed end of cylinder is fixedly connected with fixed support, and the movable end of cylinder is fixedly connected with the upper-end surface of valve gap.
The pressure of cylinder compressed air is 0.25～0.4MPa.
The angle of described valve body between top and the hypotenuse of the top board of leakage port periphery is 40～70 °.
The top of described leakage port is provided with the disappointing passage of arc, and the movable end of cylinder is fixedly connected with through the lose heart upper wall of passage and the upper-end surface of valve gap.
The movable end of described cylinder and the contacting point of disappointing passage are provided with seal arrangement.
The beneficial effects of the utility model are: owing to original deadweight lever principle being changed into cylinder as hold-down mechanism, strengthen sealing, and change linear sealing into by original sealing, reduce area of contact, thereby reduce the generation area of corrosion, improve the working life of this device, increased mechanical strength and decay resistance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of existing diffusion valve.
In accompanying drawing, 1 represents valve body, and 2 represent valve gap, and 3 represent leakage port, and 4 represent cylinder, and 5 represent fixed support, the disappointing passage of 6 representative, and 7 represent seal arrangement, and 8 represent pivoted arm, and 9 represent support arm, and 10 represent hinge.
Embodiment
The utility model is a kind of carbon black smoke diffusion valve, owing to original deadweight lever principle being changed into cylinder as hold-down mechanism, strengthen sealing, and change linear sealing into by original sealing, reduce area of contact, thereby the generation area that has reduced corrosion, in the working life of having improved this device, has increased mechanical strength and decay resistance.
Below in conjunction with accompanying drawing, the utility model is described further.
Specific embodiment, as shown in Figure 1, a kind of carbon black smoke diffusion valve, comprise valve body 1, valve gap 2, hold-down mechanism, valve gap 2 be shaped as funnel form, on the top board of valve body 1, offer leakage port 3, hold-down mechanism is fixedly connected with the upper-end surface of valve gap 2, valve gap 2 forms and is sealed and matched with leakage port 3, in order to reduce the sealing surface of seal arrangement, the toroidal that the shape of leakage port 3 is designed to inwardly open, the angle of valve body 1 between top and the hypotenuse of the top board of leakage port 3 peripheries is 40～70 °, valve body 1 is positioned at leakage port 3 peripheries like this top board and valve gap 2 form linear sealing, greatly reduce the area of contact of sealing surface, thereby reduce the generation area of corrosion, improve the working life of this device, mechanical strength and decay resistance are increased.The top of leakage port 3 is provided with the disappointing passage 6 of arc, and the movable end of cylinder 4 is fixedly connected with the upper-end surface of valve gap 2 through the upper wall of the passage 6 that loses heart, and when venting, gas is discharged by the passage 6 that loses heart, and can avoid gas directly upwards to arrange cylinder 4 is caused to corrosion.The contacting point of the movable end of cylinder 4 and disappointing passage 6 is provided with seal arrangement 7, has improved sealing, prevents that gas from being discharged by the movable end of cylinder 4 and the contacting point of disappointing passage 6.
Hold-down mechanism is changed to cylinder 4 by lever, set up fixed support 5 in the upper end of valve body 1, the fixed end of cylinder 4 is fixedly connected with fixed support 5, the movable end of cylinder 4 is fixedly connected with the upper-end surface of valve gap 2, the pressure of cylinder 4 compressed airs is 0.25～0.4MPa, like this after the pressure in valve body 1 is greater than the force value of cylinder 4, the interior gas of valve body 1 backs down valve gap 2 and exits, after the pressure in valve body 1 is less than the force value of cylinder 4, valve gap 2 is pushed back leakage port 3 places by cylinder 4, makes valve body 1 and valve gap 2 form sealing.Owing to being linear sealing, in the opening and closing process of valve gap 2, the dirt of sealing place can be eliminated, and has realized self-cleaning function.
The utility model is a kind of carbon black smoke diffusion valve, owing to original deadweight lever principle being changed into cylinder as hold-down mechanism, strengthen sealing, and change linear sealing into by original sealing, reduce area of contact, thereby the generation area that has reduced corrosion, in the working life of having improved this device, has increased mechanical strength and decay resistance.
