Abstract
The utility model relates to an S pipe sealing device, which comprises an S valve small lining end and an S valve large lining end. The S valve small lining end is mainly formed by a seal ring, an S valve shaft abrasion-resistant sleeve and an S valve small lining. The S valve large lining end is mainly formed by an outlet connection pipe and an S valve large lining. The outlet connection pipe extends into an outlet end of an S pipe, and the S valve large lining is arranged outside the connection position between the outlet end of the S pipe and the outlet connection pipe. The outlet connection pipe is characterized in that an outlet connection pipe abrasion-resistant sleeve and a decompression chamber are arranged between the outlet end of the S pipe and the outlet connection pipe, and an S valve large oil seal is arranged between the outlet connection pipe abrasion-resistant sleeve and the inner wall of the outlet end of the S pipe. The S pipe sealing device has the advantages of being good in sealing performance, long in service life and high in reliability and sufficiently meets market needs.
Description
Technical field
The utility model relates to a kind of S pipe of concrete pump, particularly discloses a kind of S tube sealing device.
Background technique
At present, the S pipe is as the critical component of concrete pump, and its related seals technology becomes the common problem of paying close attention to of user and producer.In the past, S pipe generally all relied on the outlet connecting pipe inwall in the sealing of discharge port end and added the effect that seal ring reaches sealing.Yet through the feedback of the product use condition of putting on market for a long time, this sealing effect is not fine, the easy stress deformation of Sealing, and the spillage phenomenon often appears in work after a period of time easily.
Summary of the invention
The purpose of the utility model is to overcome the problem that exists in the existing technology, and a kind of good seal performance, long service life, S tube sealing device that reliability is high are provided.
The utility model is achieved in that a kind of S tube sealing device, comprises the little lining end of S valve, S valve Large lining end, and the little lining end of said S valve mainly is made up of seal ring, S valve shaft wear-resistant sleeve, the little lining of S valve; Said S valve Large lining end mainly is made up of outlet connecting pipe, S valve Large lining; Said outlet connecting pipe stretches into S pipe outlet end; The outside of said S pipe outlet end and outlet connecting pipe joint is provided with S valve Large lining; It is characterized in that: be provided with outlet connecting pipe wear-resistant sleeve and pressure-releasing chamber between said S pipe outlet end and the outlet connecting pipe, be provided with the big oil sealing of S valve between the inwall of said outlet connecting pipe wear-resistant sleeve and S pipe outlet end.
Be provided with S valve middle cover between the outer wall of said S pipe outlet end and the S valve Large lining, be provided with the rod seal part between the outer wall of said S valve middle cover and S pipe outlet end.
Be provided with self oiling bearing between said S valve shaft wear-resistant sleeve and the little lining of S valve.
Be provided with dust ring between the afterbody of said self oiling bearing and the little lining of S valve.
The tail end of the little lining of said S valve is provided with the tegillum rubber cushion.
The seal ring of the little lining end of said S valve is star-like seal ring.
The beneficial effect of the utility model is: 1, between S pipe outlet end that makes the utility model under the cooperation of S valve wear-resistant sleeve and the big oil sealing of S valve and outlet connecting pipe, form the sealing of first road; And the outer wall of S pipe outlet end and the S valve middle cover between the S valve Large lining and rod seal part make the utility model realize the sealing of second road; And formation pressure-releasing chamber; Two roads are sealed into rotary seal; Do not have impact force power and extrusion-deformation, the utlity model has good seal performance, long service life, advantage that reliability is high, satisfied the market demand thereby make.2, change traditional guidance tape into self oiling bearing, the support bearing ability is stronger, and amount of deformation is littler, and lubricating condition and wear resistance are better, reduces the seal loading formation abrasion.Use star-like seal ring 3.S manage little cover end instead by 0 original type circle, high-pressure tightness is better, has prevented the useless leakage of lubricant oil.The afterbody of the little lining of S valve is provided with dust ring, the tegillum rubber cushion seals, and the impurity that produces in the work of permission lubricant oil one-way flushing prevents that the hopper concrete from getting into race ring under squeezed state, cause seal failure.
