Abstract
An adjustable isolating cavity sleeve gasket comprises a pressure regulating sleeve and a seal seat, wherein a ring-shaped groove is arranged in the seal seat, a sandwich Y-type seal ring is mounted in the seal seat, an O-shaped seal ring is arranged on the outer wall of the seal seat, the pressure regulating sleeve and the seal seat are connected through screws, the sandwich Y-type seal ring is closely clamped on a ring-shaped lug boss in the seal seat by the pressure regulating sleeve, and an adjusting gap is left between the pressure regulating sleeve and the seal seat. When in use, the seal seat is sleeved on a slide block, and is pressed into a ring-shaped groove on a box body, and the pressure regulating sleeve is rotated to regulate. The adjustable isolating cavity sleeve gasket has simple structure, convenient installation and adjustment, which further reaches a sealing effect only through rotating the pressure regulating sleeve and a little pressing the sandwich Y-type seal ring, and can be repeatedly regulated and used for many times, each adjustable isolating cavity sleeve gasket can be used about 13 months, which improves the service span of a sealing device, and saves production cost.
Description
Technical field
The utility model relates to a kind of seal arrangement, is particularly useful for the pumping plant oil sealing.
Background technique
Known separate cavities oil sealing has two kinds at present, and a kind of is that the oil sealing outside seals with O type circle, and the inboard adopts the rubber compacting to seal, and another kind is that O type circle is not with in the outside, directly suppresses with rubber and carries out interior external sealed.No matter be that a kind of sealing, in use for some time, owing to reasons such as mechanical wears, cause sealability to descend, oil impregnate and a large amount of oil leakage phenomenon appear, cause mine to stop production, serious may cause in the crankcase hydraulic pressure oil leakage to the greatest extent, check and untimelyly also may cause bearing shell to stick on the bent axle (to claim axis tile again).That also have in addition the gear of gear-box when the high speed rotating because oil starvation causes the damage of gear and bearing, give and overhaul and maintenance brings sizable difficulty.These two kinds of oil sealings approximately can only use about one month in this case, just must more renew, and the time of replacing is approximately wanted several hrs, and the lubricant oil about about 20Kg is all wasted in each replacing.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of adjustable separate cavities stuffing box gland, to overcome the problems referred to above, improve working life, save production cost.
The technological scheme that solution the utility model problem is taked is: form adjustable separate cavities stuffing box gland by pressure-regulating sleeve and sealing seat, there is an annular boss sealing seat the inside, sandwich y-type seal ring is contained in the sealing seat the inside, on the sealing seat outer wall, be provided with an O RunddichtringO, pressure-regulating sleeve and sealing seat are by being threaded, pressure-regulating sleeve is pressed on sandwich y-type seal ring on the annular boss of sealing seat the inside, leaves the adjusting play between pressure-regulating sleeve and sealing seat.
Dismounting is provided with removal hole on the sealing seat peripheric surface for convenience.
Adjust for convenience, on the pressure-regulating sleeve peripheric surface, be provided with dismounting and adjust handle hole.
Good effect of the present utility model is: simple in structure, install easy to adjust, when sandwich Y type sealing wear when revealing, as long as once the pressure-regulating sleeve turn, sandwich Y-shaped ring is pressed a bit, reached sealing effect again, but the repeated multiple times adjustment is used, each available about 13 months, in the working life of having improved seal arrangement, saved cost of production; When sealing reaches when needing to change working life,, screw with the M6 bolt again and take out sealing seat in the removal hole as long as pressure-regulating sleeve is unloaded, behind the sandwich y-type seal ring that more renews, pressure-regulating sleeve is screwed on, whole process only needed for 10 a few minutes can finish again, and is very convenient quick.
Description of drawings
Accompanying drawing is the phase diagram of installing and using of the present utility model
Embodiment
The utility model is made up of pressure-regulating sleeve 1 and sealing seat 4, its user mode as shown in drawings, there is a circular groove 10 to be mainly used in spacing sandwich y-type seal ring in sealing seat 4 the insides, sandwich y-type seal ring 8 is contained in sealing seat 4 the insides, on sealing seat 4 peripheric surfaces, be provided with removal hole 7, on sealing seat 4 outer walls, be provided with an O RunddichtringO 6, be used for the sealing between casing 5 and the sealing seat 4; Pressure-regulating sleeve 1 and sealing seat 4 are by being threaded, and pressure-regulating sleeve 1 is pressed on sandwich y-type seal ring 8 on the circular groove 10 of sealing seat 4 the insides, leaves adjusting play 3 between pressure-regulating sleeve 1 and sealing seat 4; Be provided with dismounting and adjust handle hole 2 on pressure-regulating sleeve 1 peripheric surface, when needing to adjust, a spike is inserted dismounting adjust handle hole 2, turning clockwise promptly compresses sandwich y-type seal ring 8 and seals, and is rotated counterclockwise the promptly detachable cover 1 of adjusting.
During use, sandwich y-type seal ring 8 is contained in sealing seat 4 the insides, O RunddichtringO 6 is contained in the seal groove on sealing seat 4 outer walls, again sealing seat 4 is enclosed within on the slide block 9, compress into the circular groove 11 on the casing 5, pressure-regulating sleeve 1 is spun on the sealing seat 4 adjusts again.
