Abstract
The utility model discloses a mechanical sealing device for high-temperature corrugated tubes, which is characterized in that a metal internal gland is arranged on a shaft sleeve through a bolt, a metal external gland is arranged on the metal internal gland, a first high-temperature corrugated tube and a second high-temperature corrugated tube are arranged on the shaft sleeve, a cooling water inlet and a cooling water outlet are arranged on the metal external gland, a pumping effect ring for leading cooling water for cooling is arranged in the position of the second high-temperature corrugated tube, and an aluminum wedge sealing ring is arranged between the metal internal gland and the metal external gland. The mechanical sealing device provided by the utility model can be used for all high-temperature medium corrugated tubes, compared with the original flexible graphite sealing gasket corrugated tube type mechanical sealing, the sealing device provided by the utility model has the advantages that the use is stable, the service life is prolong greatly, the maintenance time of equipment is prolonged, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of seal arrangement, specifically is a kind of high temperature mechanical seal device for rubber bellows that is applied to the heating agent industry.
Background technique
What the high temperature industry all adopted now is the combination of bellows+Expanded graphite, and the matching gap of well-known Expanded graphite and metal is had relatively high expectations, and the unsettled situation of sealing very easily occurs, so need improve.
The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, at this a kind of mechanical seal device for rubber bellows that can be applicable to all high temperature medias is provided.
The utility model is to realize like this; Construct a kind of high temperature mechanical seal device for rubber bellows; It is characterized in that: be provided with the metal internal gland through bolt on the axle sleeve; Be the outer gland of metal on the metal internal gland, base is provided with the first high temperature bellows and the second high temperature bellows, and the metal external pressure covers and is provided with cooling water intake end and coolant outlet end; Be provided with at the second high temperature bellows place and bring cooling water into cool off pumping effect ring, be provided with aluminium matter wedge-type seal circle between the outer gland of said metal internal gland and metal.
The sealing of the utility model rotary packing ring and stationary seal ring adopts Expanded graphite as sealing material; Outside metal, adopted the wedge-type seal circle of aluminium material between gland and the metal internal gland; Greatly improved the reliability of sealing, improved the stable of use and prolonged working life.
The advantage of the utility model is: the described mechanical seal device for rubber bellows that is applied to all high temperature medias of the utility model is compared former Expanded graphite sealing gasket bellows type mechanical seal; Novel machine envelope uses stable and the life-span improves greatly; Prolong the apparatus maintenance time, improved manufacturing efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 101, axle sleeve, 102, bolt, 103, the metal internal gland; 104, the outer gland of metal, 105, the first high temperature bellows, 106, the second high temperature bellows; 107, cooling water intake end, 108, the coolant outlet end, 109, pumping effect ring; 110, aluminium matter wedge-type seal circle, 111, the stationary ring seal ring, 112, seal ring of moving ring.
Embodiment
Below in conjunction with accompanying drawing the utility model is made detailed description:
In order to overcome the deficiency of existing technology; The utility model provides a kind of high temperature mechanical seal device for rubber bellows at this; As shown in Figure 1: as to be provided with metal internal gland 103 through bolt 102 on the axle sleeve 101; Be the outer gland 104 of metal on the metal internal gland 103, base 101 is provided with the first high temperature bellows 105 and the second high temperature bellows 106, and the outer gland 104 of metal is provided with cooling water intake end 107 and coolant outlet end 108; Be provided with at the second high temperature bellows, 106 places and bring cooling water into cool off pumping effect ring 109, be provided with aluminium matter wedge-type seal circle 110 between the outer gland 104 of said metal internal gland 103 and metal.Wherein stationary ring seal ring 111 adopts Expanded graphite, and seal ring of moving ring 112 adopts Expanded graphite.In the utility model with being provided with aluminium matter wedge-type seal circle 110 outside said metal internal gland 103 and the metal between the gland 104; Owing to be provided with the wedge-type seal circle 110 of aluminium material; Be prone to the sealing problem of unstable in the time of can solving in the existing mode between the metal internal gland 103 and the outer gland 104 of metal employing Expanded graphite seal ring; Raising machine envelope sealing effect reduces and lost efficacy greatly, extends working time.
The mechanical seal structure form adopts two very high temperature bellowss in the utility model, because high temperature reaches more than 350 ℃, common RUBBER O circle can not bear, so rotating ring sealing 112 is all adopted the Expanded graphite seal ring with stationary ring sealing 111; Between the two-stage sealing, feed cooling water, take away heat of high temperature, be provided with at the second high temperature bellows, 106 places and bring cooling water into cool off pumping effect ring 109.Adopt aluminium matter wedge-type seal circle 110 to substitute former Expanded graphite seal rings between the outer gland of interior, metal, improved machine envelope has prolonged working life.
