Abstract

The utility model proposes oil-filling type packing seal assembly.Comprise Gland, the endoporus bottom of Gland is a step hole, the endoporus transition fit supporting sleeve of Gland, supporting sleeve endoporus is provided with four stacked lip packings, the upper plane of lip packing topmost connects pressure cap, pressure cap is threaded the endoporus of Gland, pressure cap does not contact with supporting sleeve, the outer cylinder surface of supporting sleeve has annular groove, the scope of annular groove covers the altitude range of four lip packings at axial direction, at the waist location of each lip packing, the tube wall of supporting sleeve evenly has eight oil inlet holes, the tube wall of the Gland of the annular groove outside of supporting sleeve has tapped through hole to be threaded pump nozzle.By setting up an omnibearing oiling duct to each lip seal, making lip packing be in the holding state of certain pressure lubricant oil all the time, effectively improving sealing effect, reaching the object of realizing active sealing, extend the repair time, improve sealing effect.

Description

Oil-filling type packing seal assembly
technical field:
The utility model relates to mechanical seal field, specifically a kind of oil-filling type packing seal assembly.
background technique:
Packing seal is a kind of seal form of some industrial pump type seal, his advantage is that replaceable performance is good, cheap and easy to maintenance, the ubiquitous shortcoming of current packing seal is can only passive seal, after seal failure, need the screw tightening Gland, filler be compressed to there is no elasticity time, sealing lapses, need change, difficult in maintenance, maintenance cost is high.
model utility content:
In order to solve the problem, a kind of oil-filling type packing seal assembly is provided to solve the problem.
The technical solution of the utility model is: oil-filling type packing seal assembly, comprise Gland, the endoporus bottom of Gland is a step hole, the endoporus transition fit supporting sleeve of Gland, supporting sleeve endoporus is provided with four stacked lip packings, the upper plane of lip packing topmost connects pressure cap, pressure cap is threaded the endoporus of Gland, pressure cap does not contact with supporting sleeve, the outer cylinder surface of supporting sleeve has annular groove, the scope of annular groove covers the altitude range of four lip packings at axial direction, at the waist location of each lip packing, the tube wall of supporting sleeve evenly has eight oil inlet holes, the tube wall of the Gland of the annular groove outside of supporting sleeve has tapped through hole to be threaded pump nozzle.
The utility model has following beneficial effect: set up an omnibearing oiling duct by giving each lip seal, lip packing is made to be in the holding state of certain pressure lubricant oil all the time, effective raising sealing effect, reach the object of realizing active sealing, extend the repair time, improve sealing effect.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Accompanying drawing 2 is A-A sectional drawings of accompanying drawing 1.
1-Gland in figure, 2-pressure cap, 3-annular groove, 4-pump nozzle, 5-oil inlet hole, 6-supporting sleeve, 7-lip packing.
embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Shown in Fig. 1 composition graphs 2, oil-filling type packing seal assembly, comprise Gland 1, the endoporus bottom of Gland 1 is a step hole, the endoporus transition fit supporting sleeve 6 of Gland 1, transition fit makes supporting sleeve 6 can not change position in Gland 1, prevent lubricant oil excessive simultaneously, supporting sleeve 6 endoporus is provided with four stacked lip packings 7, arranging four lip packings 7 is consider, the a lot of effect less than enhanced leaktightness of quantity, rule of thumb, four stacked both can play the volume that seal action reduces stuffing box simultaneously, the upper plane of lip packing 7 topmost connects pressure cap 2, pressure cap 2 is threaded the endoporus of Gland 1, pressure cap 2 does not contact with supporting sleeve 6, the pre-tightness of the position adjustment lip packing 7 of pressure cap 2 can be regulated, the outer cylinder surface of supporting sleeve 6 has annular groove 3, the scope of annular groove 3 covers the altitude range of four lip packings 7 at axial direction, at the waist location of each lip packing 7, the tube wall of supporting sleeve 6 evenly has eight oil inlet holes 5, the tube wall of the Gland 1 of annular groove 3 outside of supporting sleeve 6 has tapped through hole to be threaded pump nozzle 4.
Utilize the one-way valve effect of pump nozzle 4, by high-pressure oil gun, lithium grease lubricant oil is injected in stuffing box, an omnibearing oiling duct is set up by giving each lip seal, lip packing 7 is made to be in the holding state of certain pressure lubricant oil all the time, effective raising sealing effect, reach the object of realizing active sealing, extend the repair time, improve sealing effect.
