Abstract
The utility model discloses a grinding device of a steam inlet valve spool and a grinding device of a steam inlet valve seat. The grinding device of the steam inlet valve spool comprises a valve spool grinding sleeve provided with a grinding layer at the top, and a retention pipe is arranged at the bottom of the valve spool grinding sleeve and is capable of limiting a valve rod from irregularly shaking during grinding. The grinding device of the steam inlet valve seat comprises a valve seat grinding sleeve provided with a grinding layer at the bottom, a retention pipe sleeves the valve seat grinding sleeve and limits grinding tracks of the valve seat grinding sleeve. The grinding devices are in surface contact with the valve spool or the valve seat during grinding, the grinding surfaces are even so as not to cause irregular grinding tracks and unevenness, and leakage points are eliminated.
Description
Technical field
The utility model relates to a kind of lapping device of inlet valve spool and the lapping device of inlet valve valve seat.
Background technology
Original Ginding process is without any aid, only to rely on personal experience to grind steam valve with grinding rifle, be easy to like this occur grinding inhomogeneous problem, and due to valve end mouth valve seat be that screw thread is installed, when grinding, milling tool just has irregular rocking like this, cause grinding track to change inconsistent, cause composition surface to have angle, after finally can causing grinding, still have leakage vapour.
Summary of the invention
In order to stop, in process of lapping, milling tool is irregular rocks, and guarantees the smooth of spool and valve seat abradant surface, and the utility model provides a kind of lapping device of inlet valve spool and the lapping device of inlet valve valve seat, and its concrete scheme is:
The lapping device of inlet valve spool, comprise that top is provided with the spool abrasive sleeve of grinding layer, described spool abrasive sleeve bottom is provided with maintenance pipe, all diameters approach with stem diameter in described maintenance pipe, and the height of described maintenance pipe is that the valve rod being connected with spool when spool is placed on the grinding layer of described spool abrasive sleeve can extend into maintenance pipe inside.
The lapping device of inlet valve valve seat, comprise that bottom is provided with the valve seat abrasive sleeve of grinding layer, described valve seat abrasive sleeve abrasive tip stretches into inlet valve inside and contacts with valve seat, between valve seat abrasive sleeve and ring flange internal diameter, be provided with maintenance pipe, described maintenance pipe outer circumference diameter is close to ring flange internal diameter, and in maintenance pipe, all diameters are close to valve seat abrasive sleeve external diameter.
The utlity model has following advantage: this lapping device is in process of lapping, and grinding layer and spool or valve seat are the face way of contact, the smooth grinding track that can not cause of abradant surface is indefinite, and the irregular phenomenon of abradant surface is eliminated leak source.
Accompanying drawing explanation
Fig. 1 is the milling tool cutaway view of inlet valve spool;
Fig. 2 is the milling tool cutaway view of inlet valve valve seat.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is illustrated:
As shown in Figure 1, the lapping device of inlet valve spool, comprise that top is provided with the spool abrasive sleeve 4 of grinding layer 3, described spool abrasive sleeve 4 inside bottom are provided with maintenance pipe 5, the interior all diameters of described maintenance pipe 5 and valve rod 2 diameters approach, and the height of described maintenance pipe 5 is that the valve rod 2 being connected with spool 1 when spool 1 is placed on the grinding layer 3 of described spool abrasive sleeve 4 can extend into maintenance pipe 5 inside.
As shown in Figure 2, the lapping device of inlet valve valve seat, comprise that bottom is provided with the valve seat abrasive sleeve 7 of grinding layer 8, described valve seat abrasive sleeve 7 abrasive tips stretch into inlet valve inside and contact with valve seat, between valve seat abrasive sleeve 7 and ring flange 9, be provided with maintenance pipe 5, described maintenance pipe 5 outer circumference diameter are close to ring flange 9 diameters, and the interior all diameters of maintenance pipe 5 are close to valve seat abrasive sleeve 7 external diameters.
Grinding layer 3 is fixed on spool abrasive sleeve end face, and spool 1 contacts with whole grinding layer 3 when being placed on and grinding on grinding layer 3, and maintenance pipe 5 is located at spool abrasive sleeve 4 bottoms, fixes valve rod 2.Make spool 1 can not produce on a large scale and rock in rotation, the spool lapping device abradant surface that the utility model provides is smooth, has solved the gas leakage problem of inlet valve.
When grinding spool 1, spool abrasive sleeve 4 is placed on level ground, valve rod 2 is placed in to maintenance pipe 5, to be ground of spool 1 contacts with the grinding layer 3 at spool abrasive sleeve 4 tops, and spool 1 is ground.On described grinding layer 3, can be the bull ring with frosting, can be also the grinding agent that is attached to spool abrasive sleeve end face.
The grinding layer 8 of valve seat abrasive sleeve is located on the bottom surface of described valve seat abrasive sleeve 7, width and valve seat are close, during grinding, need rotate valve seat abrasive sleeve 7, but due to gapped between valve seat abrasive sleeve 7 peripheries and ring flange 9 internal diameters, cause in process of lapping valve seat abrasive sleeve 7 to produce to rock abradant surface stressed unstable, need between valve seat abrasive sleeve 7 and ring flange 9 internal diameters, also establish a maintenance pipe 5.
When grinding valve seat, first maintenance pipe 5 is put into inlet valve, there is the faying face matching with valve seat maintenance pipe 5 bottoms, outer wall is close to ring flange 9 inwalls, in the bottom surface of valve seat abrasive sleeve 7, grinding layer 8 is installed, and valve seat abrasive sleeve is put into maintenance pipe 5, make maintenance pipe 5 be sleeved on valve seat abrasive sleeve 7 outsides, finally at radial direction through hole 6 places of valve seat abrasive sleeve 7, place swing handle, rotate valve seat abrasive sleeve 7, valve seat is ground.
This lapping device in process of lapping, with spool or valve seat be the face way of contact, the smooth grinding track that can not cause of abradant surface is indefinite, the irregular phenomenon of abradant surface is eliminated leak source.
