Description
Technical field
The present invention relates to valve technology field, specifically a kind of pipeline valve, be applicable to the super sized type pipeline valve that in industrial sulphuric acid production, in conveying high-temperature gas, dust-laden is more.
Background technique
Carrying high-temperature flue gas pipeline to commonly use valve in gas washing in SA production is hard sealing flange formula stainless steel butterfly valve, and material is G/F
4, between hard seal butterfly valve butterfly plate and valve body, gap is minimum, and flue butterfly valve generally adopts level to install, in flue gas during smelting, dust-laden is many, large containing saturated water amount, and after in high velocity smoke conveying, flue dust and moisture mix, viscosity is large, easily be bonded on butterfly plate and valve body, especially descend on valve body.After using a period of time, during valve switch, resistance increases gradually, not easily closes, and affects the quality of production; Long-time use butterfly valve, finally there will be valve stuck phenomenon, needs to change valve, is greater than the flue butterfly valve body used of DN2000 and valve plate casting requires height for pipe diameter, and expensive, the frequent replacing of valve adds enterprise's cost of production.
Summary of the invention
The object of this invention is to provide a kind of pipeline valve, cause the easy blocking of hard seal butterfly valve to solve during sulfuric acid industry is produced because carrying the high flue gas of dust loading, frequent valve of changing is to the problem of enterprise's increase cost of production.
For solving the problems of the technologies described above, the present invention take technological scheme as follows:
A kind of pipeline valve, it comprises upper valve body, lower valve body, described upper valve body, opposedly on described lower valve body be provided with the identical valve body hole of size, the bilateral symmetry of described lower valve body is provided with reel, banded spool is provided with in the middle of described upper valve body and described lower valve body, described banded spool is at least provided with 2 spool bore, distance between 2 adjacent valve core bore is greater than the diameter of described valve body hole, the side of described banded spool is provided with projection, the two ends of described banded spool are connected respectively at described reel, described reel is connected with speed reducer, the bottom surface of described upper valve body is provided with upper valve body sealing, the end face of described lower valve body is provided with and seals opposite lower valve seal with described upper valve body.
As a further improvement on the present invention, described reel is provided with snubber, and described snubber is provided with limiting board.
Further improve as of the present invention, the end face of described upper valve body is connected with one end of slip joint, the other end of described slip joint is connected with flange, the upper side wall both sides of described upper valve body are provided with lower supporting plate, described lower supporting plate is connected with the lower hinge of cylinder by lower bearing pin, and the upper hinge of described cylinder is connected with the upper backup pad being arranged on described flange both sides.
Further improve as of the present invention, described lower valve body bilateral symmetry is provided with two pieces of reducing gear dunnages, and described speed reducer is arranged in reducing gear, and described reducing gear is arranged in described reducing gear dunnage by fastening screw trip bolt.
Further improve as of the present invention, described valve body hole is identical with the diameter of described spool bore.
The present invention adopts the banded spool being provided with hole, is rotated under speed reducer controls by the reel of lower valve body both sides, and band movable valve plug moves left and right, and completes the unlatching of valve and closed control; When spool moves, by the flue dust wiped clean in the lump dropped on valve body, spool, efficiently solve because of the accumulation of flue dust on valve and the problem causing valve to be blocked; The shift motion of spool is controlled by snubber; Upper valve body arranges cylinder, cylinder passes into pressurized gas makes upper valve body compress upper valve body sealing, banded spool and lower valve seal under the effect of cylinder pretightening force, thus ensure banded spool upper-lower seal face smoke tight, improve the safety reliability of production; Upper valve body arranges slip joint, and slip joint carries out telescopic moving, guarantees the flexible motion of upper valve body.By use of the present invention, considerably increase the working life of valve, saved cost of production, bring larger economic benefit to enterprise.

Embodiment
Below in conjunction with accompanying drawing, technological scheme of the present invention is described in further detail.
A kind of pipeline valve as shown in Figures 1 to 4, it comprises upper valve body 7, lower valve body 1, upper valve body 1, opposedly on lower valve body 2 be provided with the identical valve body hole of size 25, the bilateral symmetry of lower valve body 1 is provided with reel 19, banded spool 5 is provided with in the middle of upper valve body 7 and lower valve body 1, banded spool 5 is at least provided with 2 spool bore 23, distance between 2 adjacent valve core bore 23 is greater than the diameter of valve body hole 25, the side of banded spool 5 is provided with 3 projections 24, the two ends of banded spool 5 are connected respectively at reel 19, reel 19 is connected with speed reducer 4, the bottom surface of upper valve body 7 is provided with upper valve body sealing 6, the end face of lower valve body 1 is provided with and seals 6 opposite lower valve seals 2 with upper valve body.
Reel 19 is provided with snubber 21, and snubber 21 is provided with limiting board 22.
The end face of upper valve body 7 is connected with one end of slip joint 16, the other end of slip joint 16 is connected with flange 15, the upper side wall both sides of upper valve body 7 are provided with lower supporting plate 8, lower supporting plate 8 is connected with the lower hinge 10 of cylinder 11 by lower bearing pin 9, and the upper hinge 12 of cylinder 11 is connected with the upper backup pad 13 being arranged on flange 15 both sides.
Lower valve body 1 bilateral symmetry is provided with two pieces of reducing gear dunnages 17, and speed reducer 4 is arranged in reducing gear 3, and reducing gear 3 is arranged in reducing gear dunnage 17 by fastening screw trip bolt 18.
Valve body hole 25 is identical with the diameter of spool bore 23.
Cylinder 11 inputs pressurized gas, and under the pretightening force effect of cylinder 11, upper valve body sealing 6 is compacted on banded spool 5, and banded spool 5 moves down and lower valve seal 2 close contact, and upper valve body 7 and lower valve body 1 are interlocked.When spool needs closed, start speed reducer 4, reel 19 drives banded spool 5 to move, solid position between 2 adjacent valve core bore 23 moves to opposite side from the side of valve body hole 25, until cover valve body hole 25 completely, the limited plate 22 of projection 24 on banded spool 5 blocks, and banded spool 5 stops mobile, and spool enters Operating In Persistent Current Mode state.When spool needs to open, reel 19 drives banded spool 5 to move round about, and spool bore 23 moves and coincides with the center of valve body hole 25, and another the protruding 24 limited plates 22 on banded spool 5 block, banded spool 5 stops mobile, and spool enters unlatching working state.The gas flow by pipeline valve can be controlled by the size at the position that overlaps between control valve core bore 23 with valve body hole 25.
