Abstract
The utility model discloses an emptying valve, which is mainly improved in the following aspects: the emptying valve includes a valve body, a valve cover matched with and arranged at the top end of the valve body, and a drive mechanism of the valve cover; the valve cover adopts a disk-shaped structure, the bottom of the valve cover is an annular seal surface, and the seal surface is an arc; the valve body adopts a cylindrical structure, an annular support body with an arc top surface is arranged on the inner wall at the top of the valve body, a groove is arranged on the arc surface of the annular support body, and an O-shaped seal ring is mounted in the groove; and the drive mechanism of the valve cover includes a bracket arranged on the outer wall of one side of the valve body, a pneumatic motor mounted on the bracket, and a connecting rod fixedly connected with an output shaft of the pneumatic motor, wherein a pull rod vertically arranged is connected with the open end of the connecting rod, a lever is hinged at the top of the valve cover, the middle of the lever is hinged with the support rod fixedly arranged on the outer wall of the valve body, and the tail end of the lever is hinged with the connecting rod. The emptying valve has the advantages of good sealing performance, effectiveness in opening and closing, long service cycle, and conveniences for replacement, installation and disassembly.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of atmospheric valve.
Background technique
Carbon black generates in the reaction furnace section, and carbon black is mixed in the flue gas after generating, and enters collecting system through temperature adjustment several times.In collecting system, carbon powder dust separates with tail gas, and carbon powder dust enters transporting system, and tail gas then is sent to power plant's generating, and under usual condition, the tail gas atmospheric valve is cutting out.Since in start or the tail gas main component when shutting down be nitrogen, carbon dioxide or oxygen, be incombustible gas, not only unhelpful if enter exhaust system, and the ratio of oxygen reaches certain value, also has very big danger.So the requirement to atmospheric valve on the technology is that tightness is good, can open or close rapidly.
Traditionally, the carbon black plant generally adopts butterfly valve, its shortcoming is: 1) because the carbon black tail gas temperature is high and contain the moisture of a great deal of, also has a spot of sulfur dioxide in addition, and keep under the atmospheric valve normal state closing, this makes it be very easy to be corroded, and even rust is dead, critical moment can't open, and has certain danger; 2) sealing is relatively poor, if sealing is better between spool and valve body, then stuck easily, can't in time open crucial moment.
The model utility content
The utility model provides a kind of good airproof performance, and the effective atmospheric valve of opening and closing.
For solving the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of atmospheric valve, and its key improvements is: the valve gap that comprise valve body, is equipped with the valve body top and the driving mechanism of valve gap; Described valve gap is a disc-shaped structure, and its bottom is an annular sealing surface, and sealing surface is circular-arc; Described valve body is a cylinder-like structure, and it is circular-arc annular support that end face is set on the inwall of top, and the groove of annular is set on the arc surface of annular support, and the O RunddichtringO is installed in the groove; The driving mechanism of described valve gap comprises the support that is fixed on the valve body one side outer wall, rack-mount pneumatic motor, the connecting rod of fixedlying connected with the output shaft of pneumatic motor, the connecting rod open end connects the vertical pull bar that is provided with, valve gap top hinged lever, the lever middle part is hinged with the strut that is fixedly installed on the valve outer wall, lever end and rod hinge connection.
Adopt the beneficial effect that technique scheme produced to be: lever to be set at the valve body top; lever one end and valve gap are hinged; hinged being hinged on the support in middle part; tail end and rod hinge connection are because connecting rod is subjected to pneumatic motor driven, so start or can open rapidly when shutting down; the sealing surface of the annular support at valve body top is provided with the O RunddichtringO on the one hand in addition; can effectively improve the sealing effect of valve gap and valve body, and life cycle is long, it is convenient to change.
