Abstract
The utility model discloses a seal casing applied to the tail end of a pump truck S tube, comprising a seal seat, wherein the seal seat is an annular convex platform; a chrome plated casing is connected into the seal seat through a screw; an annular seal groove is formed in the circumference of the inner wall of the seal seat; a sealing element is arranged in the seal groove. The seal casing applied to the tail end of the S tube of the pump truck adopts the method that the chrome plated casing is sleeved in the seal seat, thereby effectively avoiding the risk of scrap of the entire pump truck S tube, after the method of the chrome plated casing is adopted, liquid concrete only damages the chrome plated casing, only the chrome plated casing needs to be replaced, the cost is lower, replacing of the entire pump truck S tube is not needed, and the cost is reduced.
Description
Technical field
The utility model relates to a kind of stuffing box gland for pump truck S pipe tail end, belongs to technical field of engineering machinery.
Background technique
Pump truck S pipe is immersed in hopper liquid concrete and carries out reciprocally swinging work, and pump truck S pipe outlet end is exit seal seat, uses multiple exit seal to reach concrete sealing effect.Aborning, inevitably liquid concrete can enter destruction exit seal in exit seal, and the sealed end of the pump truck S pipe that can wear and tear, and causes pump truck S pipe to scrap.
Model utility content
Model utility object: the purpose of this utility model is in order to solve above the deficiencies in the prior art, provides a kind of stuffing box gland for pump truck S pipe tail end, has extended the working life of pump truck S pipe, has reduced cost.
Technological scheme: the stuffing box gland for pump truck S pipe tail end described in the utility model, its objective is such realization, a kind of stuffing box gland for pump truck S pipe tail end, comprise sealing seat, described sealing seat is annular boss, in sealing seat, be bolted with chromium-plated axle sleeve, on described sealing seat inwall circumference, offer annular seal groove, in seal groove, be provided with Sealing.
Described Sealing is " O " RunddichtringO or " Y " RunddichtringO.
Beneficial effect: the stuffing box gland for pump truck S pipe tail end described in the utility model has adopted the method for sheathed chromium-plated axle sleeve in sealing seat, the risk that can effectively avoid whole pump truck S pipe to scrap, adopted after the method for chromium-plated axle sleeve, what liquid concrete destroyed is chromium-plated axle sleeve, only need to change chromium-plated axle sleeve just passable, cost is lower, need not change whole pump truck S pipe, has saved cost.
