Abstract
The utility model relates to an annular air bag type sealing ring used for a dewatering bin. The utility model is characterized in that an inflating valve of the sealing ring adopts the self-sealing principle, the prime inflating valve made of copper is changed to a segment of rubber pipe, and the rubber pipe is interference fit with an air intake passage and an exhaust passage of a gate for removing dust. After an air bag is inflated, the rubber pipe expands tightly on the wall of the air passages, and an additional sealing ring is not needed. Air pressure is higher, and the rubber pipe adhibits the wall of the air passages further tightly. The sealing ring has the advantages of simple structure, convenient installation, good sealing and duration.
Description
The utility model relates to a kind of sealing mechanism, in particular for the bellows seal circle of drainage bin ash-removing door sealing.
Chinese patent ZL95234388.6, ZL95234389.4, ZL95234390.8 number disclosed drainage bin, advance in slurry and the dehydration at it, guarantee that the watertight crucial Sealing of its lower end ash discharge gate is a bellows seal circle in the form of a ring, and the reliability of sealing circle sealing depends on the lasting maintenance of its inner chamber air pressure.And the seal ring of similar products at home and abroad, its valve cock is made of copper, what lean on the sealing of air flue is twice " O " type seal ring, poorly sealed, and day by day loses efficacy.
The purpose of this utility model is to solve a difficult problem poorly sealed by the bellows seal circle and that be easy to lose efficacy.
The utility model is improved the valve cock of existing ring-shaped gasbag formula seal ring, and main points are that its valve cock taked the principle of " selfsealings ", is about to former valve cock made of copper and changes one section sebific duct into, is interference fit with the intake and exhaust port of ash discharge gate.Behind airbag aeration, the sebific duct swelling must not add seal ring in addition on airway walls.Air pressure is higher, and it is tighter that sebific duct and airway walls are pasted.
Valve cock and air bag are one, have the endless metal liner between the two.
The utility model is compared with existing bellows seal circle, has simple in structurely, easy for installation, seals tight and lasting advantage.
Description of drawings:
Fig. 1 is the mounting point figure of bellows seal circle described in the utility model on the drainage bin gate.
Fig. 2 is a bellows seal circle valve cock part amplification assumption diagram among Fig. 1.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail.
As shown in Figure 1, bellows seal circle 2 is contained in the bottom of flange-type ash discharge gate 1, and door-plate 3 is pressed on the air bag 4 of bellows seal circle 2.
As shown in Figure 2, the sebific duct valve cock 5 on the bellows seal circle 2 inserts with certain interference in the intake and exhaust port 6 of ash discharge gate 1, and valve cock 5 is made one with air bag 4, is added with metal liner 7 between the two.
Claims (2)
1, a kind of drainage bin bellows seal circle in the form of a ring, has valve cock [5], it is characterized in that: valve cock [5] is one section sebific duct, is interference fit with the intake and exhaust port [6] of ash discharge gate [1].
2, according to the described bellows seal circle of claim 1, it is characterized in that: valve cock [5] is one with air bag [4], has endless metal liner [7] between the two.
