Abstract
A water inlet and outlet sealing device mainly resolves the problem of water leakage of a water inlet pipe and a water outlet pipe of a cold slag discharger, and comprises a water inlet pipe, a water outlet pipe, a hollow shaft, a stainless steel pipe and a press sleeve. The water inlet pipe and the water outlet pipe are sleeved inside the stainless steel pipe, the hollow shaft is sleeved outside the stainless steel pipe, a shaft sleeve connected with the press sleeve through a bolt is arranged at a fit end of the hollow shaft with the stainless steel pipe, and graphite packing is arranged between the inner side of the shaft sleeve and the press sleeve. The water inlet and outlet sealing device is reliable in sealing, expansion and contraction of the shaft is reduced, cracks are avoided, and water leakage is prevented.
Description
Technical field
The utility model relates to a kind of seal arrangement that is used for cold slag slagging machine, specifically a kind of water inlet and outlet seal arrangement.
Background technique
Inlet and outlet system is very important on a cold slag slagging machine part; Traditional inlet and outlet system structure is for being provided with hollow shaft and protecting jacket in the outside of intake pipe and outlet pipe; But because hollow shaft and protecting jacket two ends are welding; The expansion that causes of inlet and outlet system when work HTHP and the shrinkage that causes when not working can not well be regulated like this; So cause relevant weld seam to be prone to split cooling water is leaked outside, need a kind of water inlet and outlet seal arrangement to guarantee the normal service behaviour of cold slag slagging machine at present.
The model utility content
The purpose of the utility model is to provide a kind of water inlet and outlet seal arrangement, and the sealing device can be avoided the inlet and outlet system water leakage phenomenon effectively.
The technological scheme that its technical problem of the utility model solution is taked is: the water inlet and outlet seal arrangement; It is characterized in that; Comprise intake pipe, outlet pipe, hollow shaft, Stainless Steel Tube and gland; Said intake pipe and outlet pipe are nested with at Stainless Steel Tube inner, and said hollow shaft is nested with the outside at Stainless Steel Tube; Hollow shaft is provided with axle sleeve with the abutting end of Stainless Steel Tube and is connected through bolt with gland, is provided with the graphite packing between axle sleeve inboard and the gland.
Compared with prior art; The utlity model has following outstanding beneficial effect: intake pipe and outlet pipe are positioned at the inside of Stainless Steel Tube; Between hollow shaft and Stainless Steel Tube, be provided with the surplus of expanding with heat and contract with cold; The graphite packing that is provided with axle sleeve between hollow shaft and the Stainless Steel Tube and is applicable to static sealing under the high-temperature and high-pressure conditions, an end of hollow shaft are for to be connected with gland through bolt, and above structure makes weld seam not easy to crack; Sealing is reliable, the phenomenon of effectively avoiding the cold slag slagging machine inlet and outlet system to leak.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 cylindrical shell, 2 return pipes, 3 hollow shafts, 4 axle sleeves, 5 Stainless Steel Tubes, 6 graphite packings, 7 glands, 8 outlet pipes, 9 intake pipes, 10 bolts, 11 cylindrical shell end caps.
Embodiment
As shown in Figure 1, the water inlet and outlet seal arrangement comprises intake pipe 9, outlet pipe 8, hollow shaft 3, Stainless Steel Tube 5 and gland 7, and said intake pipe 9 is nested with in Stainless Steel Tube 5 inside with outlet pipe 8, and said hollow shaft 3 is nested with the outside at Stainless Steel Tube 5; Hollow shaft 3 is provided with axle sleeve 4 with the abutting end of Stainless Steel Tube 5 and is connected through bolt 10 with gland 7, is provided with graphite packing 6 between axle sleeve 4 inboards and the gland 7.
During use, hollow shaft 3 welding are fixed on the cylindrical shell end cap 11, and intake pipe 9 feeds the cooling channel of cylindrical shell 1 inside, and return pipe 2 stretches out back access outlet pipe 8 in cylindrical shell 1.The cooling channel that cooling water is got in the cylindrical shell 1 by intake pipe 9, circulation in the cooling channel is after return pipe 2 flows into outlet pipe 8 discharges.Be provided with the surplus of expanding with heat and contract with cold between Stainless Steel Tube 5 and the hollow shaft 3; Effectively avoid weld seam to ftracture because of expanding with heat and contract with cold; Axle sleeve 4, graphite packing 6 and gland 7 all can play good static sealing effect; Effectively avoid cold slag slagging machine water leakage phenomenon to occur, prolonged the working life of cold slag slagging machine.
