Description
Technical field
This utility model is related to food apparatus technical field of sealing technology, specifically refers to a kind of food apparatus mechanical seal.
Background technology
At present, for the mechanical seal of food apparatus pump shaft, typically by alignment pin come transmitting torque, and alignment pin
Setting, need to carry out the machining of mounting hole site, and to ensure the reliability of moment of torsion transmission, mounting hole site dimension precision requirement
It is not low.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of food apparatus mechanical seal, the food apparatus machinery
Sealing need not adopt alignment pin transmitting torque, and can effectively reduce the machining accuracy of torque transfer member.
Technical solution of the present utility model is to provide a kind of food apparatus mechanical seal, including gap is linked in and sets
Media end stationary ring that atmosphere end stationary ring, gap on standby pump shaft is linked on equipment pump shaft, gap are linked on equipment pump shaft
Spring, for filling the seal receptacle of atmosphere end stationary ring and media end stationary ring, is provided between described spring and atmosphere end stationary ring
One throw-out collar, is provided with the second throw-out collar, the first described throw-out collar and the second throw-out collar gap between described spring and media end stationary ring
It is linked on equipment pump shaft, projection or groove is provided with the first described throw-out collar and the second throw-out collar, is set on described seal receptacle
There is the groove or projection with raised or recess dress.
The groove being arranged on seal receptacle or projection are circumferentially uniform, and moment of torsion is uniformly transferred, overall steady.
The atmosphere end stationary ring end and media end stationary ring end abutted against with throw-out collar is provided with outside the taper that external diameter is gradually decreased
Wall, effectively reduces the end size of atmosphere end stationary ring and media end stationary ring, between increased between corresponding stationary ring and seal receptacle
Gap space.
Food apparatus mechanical seal of the present utility model, by the setting of throw-out collar, and utilizes matching on throw-out collar and seal receptacle
The raised and groove of dress, effectively delivers moment of torsion in the case of without using alignment pin, and raised and Pocket Machining is convenient, together
When throw-out collar setting, increased indirectly spring and corresponding stationary ring end compresses area, makes spring compress reliability.
Description of the drawings
Accompanying drawing is the cross section structure diagram of food apparatus mechanical seal of the present utility model.
As shown in the figure：1 equipment pump shaft, 2 atmosphere end stationary rings, 3 media end stationary rings, 4 springs, 5 first throw-out collars, 6 second throw-out collars,
7 is raised, 8 grooves, 9 seal receptacles, 10 conical outer walls, 11 bath ducts, and 12 atmosphere end dynamic and static ring end face seal chambers, 13 media ends are moved
Stationary ring end face seal chamber.
Specific embodiment
This utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：
As illustrated, food apparatus mechanical seal of the present utility model, including gap is linked in the air on equipment pump shaft 1
Spring 4 that the end media end stationary ring 3, gap that is linked on equipment pump shaft 1 of stationary ring 2, gap is linked on equipment pump shaft 1, it is used for
The seal receptacle 9 of dress atmosphere end stationary ring 2 and media end stationary ring 3.
The first throw-out collar 5, described spring 4 and media end stationary ring 3 are provided between described spring 4 and atmosphere end stationary ring 2
Between be provided with the second throw-out collar 6.The first described throw-out collar 5 and 6 gap of the second throw-out collar are linked on equipment pump shaft 1.Described
Raised 7 or groove are provided with one throw-out collar 5 and the second throw-out collar 6, described seal receptacle 9 is provided with and raised 7 or recess dress
Groove 8 or projection.
The groove 8 being arranged on seal receptacle 9 or projection are circumferentially uniform, in the present embodiment, are arranged on seal receptacle 9
For groove 8.
2 end of atmosphere end stationary ring and 3 end of media end stationary ring abutted against with throw-out collar is provided with the taper that external diameter is gradually decreased
Outer wall 10.
Described seal receptacle 9 is provided with bath duct 11, described bath duct 11 and atmosphere end dynamic and static ring end face seal
Chamber 12, media end dynamic and static ring end face seal chamber 13 connect.After bath duct 11 is arranged, atmosphere end dynamic and static ring sealing can be reduced in time
The temperature of end face and media end dynamic and static ring sealing end face, and after throw-out collar is arranged, 2 end of atmosphere end stationary ring and media end stationary ring can be made
The outer wall of 3 ends is made that size is smaller, can so increase the clearance space between corresponding stationary ring and seal receptacle, can accommodate more
Water under high pressure so that the temperature of atmosphere end dynamic and static ring sealing end face and media end dynamic and static ring sealing end face more can be dropped in time
It is low.
