Abstract
A grinding device for a safety valve sealing surface for grinding and repairing a full-open sealed safety valve comprises a gear assembly 1, a disc 5, a spring 35, a valve seat grinding shaft 37, a safety valve 40, a safety valve seat 41, glass 42, a speed reducer 45 and the like, wherein the gear assembly 1 is respectively connected with the disc 5 and the disc 14, the glass 44 is arranged on the gear assembly 1, the gear assembly 1 is connected with the valve seat grinding shaft 37, the spring 35 is sleeved on the valve seat grinding shaft 37, a rectangular disc 26 is arranged at the upper part of the grinding device and can effectively generate friction with the safety valve sealing surface, an operator can replace a grinding body at any time without dismounting the safety valve seat, and therefore the grinding quality is improved, the production cost is reduced, and the labor intensity is reduced.
Description
Relate to the field
The utility model relates to a kind of grinding of opening sealed safety valve entirely to be repaired, and specifically, is a kind of lapping device of safety valve sealing surface.
Background technology
Existing safety valve grinding machinery drives to grind by reductor and rotates.Abrasive disk is the steel body, produces it by specialized factory and costs an arm and a leg, and because of weight reaches 40 kilograms, so lapping device is bulky, mobility is poor.Grind in use that the flatness of abrasive disk reduces behind the safety valve sealing surface of some, the flatness of repairing its abrasive disk is extremely difficult, and the abrasive disk quality can't guarantee that in addition when repairing, safety valve is scrapped because of dismantling.
Technology contents
The purpose of this utility model is to provide effectively and produces friction with the safety valve sealing surface, operating personnel do not dismount and mount full valve seat, can change abrasive body at any time, thereby improve the lapping device of Grinding Quality and a kind of safety valve sealing surface that reduces production costs, reduces labor intensity.
The utility model is achieved in that and comprises gear assembly 1, disk 5, lower support dish 10, disk 14, rectangular dish 26, spring 35, valve seat grinding shaft 37, supporting disk fixed bar 38, safety valve 40, emergency valve seat 41, glass 42, reductor 45, upper support dish 46, reductor 45 is connected with gear assembly 1, lower support dish 10 is arranged at the bottom at device, gear assembly 1 and disk 5, disk 14 connects respectively, be equipped with glass 44 on the gear assembly 1, gear assembly 1 is connected with valve seat grinding shaft 37, be with spring 35 on the valve seat grinding shaft 37, the top of this device is provided with rectangular dish 26.
The utility model also adopts following technical scheme:
Valve seat grinding shaft 37 tops are equipped with glass 42, and emergency valve seat 41 is arranged.
Safety valve flap 43 is connected to the lower end of the grinding shaft 37 that spring 35 is housed, and contacts with glass 44 on the disk 5.
Advantage of the present utility model is: glass is installed on the gear, the driven gear that reductor drives on the master gear drive upper support dish is formed rotating mechanism, operating personnel place bearing fixing to put on safety valve, the spring grinding shaft of glass is housed on the driven gear, friction valve seat when the spring grinding shaft rotates, reach and to dismantle the safety valve valve seat, grind the purpose of valve seat simultaneously.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
As shown in the figure, safety valve 40 is put on the bearing fixing sleeve 26, be connected with gear assembly 1 at upper support dish 46, the master gear rotation of glass 44 by reductor 45 driven gear assemblies 1 is installed on gear assembly 1, the grinding shaft 37 that spring 35 is housed on the driven gear of gear assembly 1 rotates thereupon, and glass 42 grinds by the rotation of grinding shaft 37 that spring 35 is housed.When glass 42 planes are damaged, change, install new glass, continue polish process.
The novel grinding safety valve sealing surface of this use is finished by following:
The master gear of reductor 45 driven gear assemblies 1 rotates, thereby driving three driven gears rotates, be installed in grinding shaft 37 on the driven gear, that spring 35 is housed rotates thereupon, glass 42 is equipped with in grinding shaft 37 upper ends, the safety valve 40 that is placed on rectangular dish 26 is motionless, glass 42 and valve seat 41 produce friction, reach the purpose of grinding.Safety valve flap 43 with the need grinding, be connected to the lower end of the grinding shaft 37 that spring 35 is housed, contact the generation friction with the glass 44 on the disk 5, upper support dish 46 is connected with gear assembly 1, lower support dish 10 is connected with gear assembly 1, thereby the direction of motion of gear and gear reaches the purpose of grinding on the contrary like this.
