Description
Technical field
The invention belongs to station boiler smoke wind pipe accessory technical fields, and in particular to a kind of refractory seals butterfly isolation
Door gear.
Background technique
Hot air isolating door is mainly used for station boiler smoke wind pipe system various subsidiary engines (pressure fan, air preheater, coal pulverizer
Deng) reliable isolation, facilitate isolation of system, switching and carry out corresponding service work.For many years, each power plant is because of isolation door isolation
Be not closed completely, dust stratification is stuck, high temperature shutoff is not flexible, in isolation door leakage etc. and passively shut down phenomenon and increase, cause maintenance tired
It is difficult.
This transformation completely cuts off the following problem of door for existing interposer type: 1, the hot air isolating door inner disk root long phase is living
It is dynamic, it is poorly sealed, cause heat primary air to leak, coal pulverizer internal temperature is higher when stoppage in transit, influences coal pulverizer internal overhaul；2, because
Hot air isolating door is board plug type, is easy dust stratification in the trench, causes isolation door switch not in place, influences coal pulverizer and normally open
Stop；3, hot air isolating door adjustment in cold air condition finishes, and because of packing and seal box high temperature deformation after starting, turns off not sternly, causes inside and outside
Leakage is serious；4, structure is complicated, needs locking device, reinforces sealing, increases maintenance cost.
Summary of the invention
The present invention is adopted the technical scheme that in order to achieve the above objectives:
A kind of refractory seals butterfly isolation door gear, including toroidal shell, shell upper and lower ends are separately installed with diameter changing nipple,
Diameter changing nipple is used for connecting pipe；Sealing shroud is installed along inner ring in the shell, sealing is fitted with isolation on sealing shroud
Door completely cuts off on door and is equipped with self-compensating device；The self-compensating device includes high temperature spring and cranking arm, it is described crank arm one end with every
The hinged seat that exhausted door is equipped on centerline is hinged, cranks arm and is equipped with high temperature spring, upper installation of cranking arm between the other end and isolation door
There is main shaft, main shaft can drive rotary motion of cranking arm, and main shaft both ends pass through shell, and the main shaft is pacified with respect to shell circle ring center bias
Dress, and the opposite rotatable movement of shell.
Preferably, it is equipped with retaining ring between the shell and isolation door, for protecting isolation door.
Preferably, the shell inner ring is installed with expansion joint, and expansion joint is located at the sealing station of isolation door and sealing shroud.
Preferably, the isolation door and sealing shroud are all made of metal material.
Preferably, described crank arm is coupled with main shaft by keyway.
Preferably, it is equipped with short connector between the high temperature spring and isolation door, high temperature spring and is equipped with length between cranking arm
Connector.
Preferably, the main shaft both ends and housing junction are equipped with copper sheathing.
Preferably, described main shaft one end is equipped with pointer and dial, is used to refer to isolation door opening position.
Preferably, the self-compensating device is symmetrically arranged with 2 along shell circle ring center.
Preferably, described main shaft one end is equipped with power device.
The advantageous effect of present invention is that:
1, former hot air isolating door form is transformed, butterfly valve type, no mobile runway, facility switching and arrangement is changed to by interposer type
Mode is flexible, and switch time is short, there is no because of dust stratification bite, fundamentally solves former hot wind insertion plate door, post position dust stratification
Seriously, it causes plate door switch not in place, fundamentally solves isolation door before and be not closed completely, leak outside in hot air isolating door
Problem facilitates the switching and retired maintenance of equipment significantly, improves the safety of service personnel；
2, using complete closed circle metallic sealing section, the feelings that former packing_seal bad seals can not be sealed normally are eliminated
Condition is isolated tight, sealed reliable, effectively eliminates interior leakage phenomenon；
3, using self compensation fit sealing device, thermal deformation difference can be effectively absorbed, equipment is reduced and answers degree, improve and set
Standby reliability, reduces maintenance cost；
4, equipment design has retaining ring protection isolation door, makes to completely cut off the extension of door service life, reliable operation, it is low to reduce its maintenance cost；
5, equipment design have expansion joint, mainly for equipment under high-temperature work environment be easy expansion, cause it is poorly sealed close, it is swollen
Swollen section is at the sealing station of isolation door and sealing shroud, and isolation door sealing position is constant after guaranteeing high temperature；
6, by designing short connector between high temperature spring and isolation door, high temperature spring and long connector is designed between cranking arm,
So that the connection of high temperature spring and door of cranking arm, completely cut off is more firm, to not break down；
7, it is equipped with pointer and dial in main shaft one end, it can be observed that the relative position of isolation door rotation, accurately controls main shaft
Revolution.
