Abstract
A safety valve seat automatic grinding device used for a pressure vessel over-pressure protection in the petroleum and chemical industry consists of a main shaft 1, a fixing sleeve 2, a bearing 3, a friction wheel 4, a planetary gear 5, a supporting sleeve 6, a retaining cover 7, a gasket 8, a spring piece 9, a lock spring 10 and a grinding head 11, etc. A motor output shaft drives the main shaft and the planetary gear to rotate, meanwhile, the planetary gear self-rotates to drive the grinding head at the lower end to implement the revolution and self-rotation; the grinding head and the planetary gear can axially implement the supplementation. The device relieves the labor intensity of workers, and improves the time efficiency and the effective utilization ratio of the grinding head.
Description
Technical field:
The utility model relates to a kind of petroleum chemical industry pressure vessel overpressure protection safety valve lapping device, specifically, is safety valve valve seat automatic grinding device.
Background technology:
In petroleum chemical industry; safety valve is widely used in the overpressure protection of pressure vessel; in the use owing to be subjected to the erosion of medium and washing away for a long time; sealing surface will produce corrosion; in periodic check; because of sealing surface corrosion and other reasons cause the safety valve sealing property not reach 20～30% of the verification amount that accounts for of instructions for use, because the sealing surface of safety of China valve adopts flat seal substantially, the grinding of sealing surface just needs finish mill.At present a kind of is to adopt flap that mill is finished, but requires flap the same with the sealing area of valve mill seat, because of the little operating difficulties of flap, can not reach the grinding requirement; A kind of specific purpose tool bistrique of another kind of processing replaces the flap handled easily, these two kinds of Ginding process all adopt hand lapping, and the reconditioning flap and the bistrique that require not stop can reach the grinding requirement, because of bistrique and valve base sealing in the process of grinding are faced mill, require the surface area of bistrique area greater than sealing surface, bistrique can produce groove in the process of grinding.And the safety valve of different model and producer need be used serial bistrique, makes the workload of bistrique reconditioning increase greatly.
Summary of the invention:
The purpose of this utility model is to develop a kind of by the buncher driving, and the automatic grinding device that the rotation of bistrique energy can be revolved round the sun is again also realized automatic compensate for wear amount.
The purpose of this utility model is achieved in that by main shaft 1, fixed cover 2, bearing 3, friction pulley 4, planetary gear 5, support set 6, door 7, pad 8, spring leaf 9, snap 1010 and bistrique 11 etc. to be formed, motor output shaft is connected with main shaft 1, the outer flank of tooth engagement of one section outer ring surface on the main shaft 1 and planet pin 5, following is fixed in the support set 6 on the planet pin 5, and planet pin 5 bottoms are connected with bistrique 11.
The utility model also adopts following technical scheme:
The effect of invention
Advantage of the present utility model is that bistrique can revolve round the sun again in rotation, compensates the bistrique wear extent automatically, has alleviated working strength of workers, has improved the effective rate of utilization of timeliness and bistrique.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is user mode figure of the present utility model.
Concrete enforcement
As shown in Figure 1, the utility model by main shaft 1, fixed cover 2, bearing 3, friction pulley 4, planetary gear 5, support set 6, door 7, pad 8, spring leaf 9, snap 10 and bistrique 11, etc. form.
The utility model is installed among the valve opening of safety valve, as shown in Figure 2, adjust the height of this device in the safety valve valve opening and realize centering by positioning disk, motor output shaft drives main shaft and planetary gear rotates, planetary gear rotation simultaneously, the bistrique that drives the lower end is realized revolution and rotation, and bistrique and planetary gear axially can realized compensation.
