Abstract
The utility model relates to a valve grinder, which is connected by a grinding disc component and a motor, the motor can drive the grinding disc component to rotate so as to grind, the utility model can be made into a valve core grinding machine or a valve seat grinding machine, and the grinding speed of the motor can be adjusted via a speed governor. The utility model adopts machine for grinding and has the advantages of rapid speed, little technical difficulty and convenient operation.
Description
The utility model relates to a kind of valve grinding machine that is used to repair valve.
The way of repairing valve at present is: stop valve, control valve, spool and valve seat are put abrasive pastes mutually to mill, till binding face loses vestige.To gate valve, binding face adopts scraper scraping one deck, and the degree of depth is the degree of depth of vestige.These all want manual operations, time-consuming taking a lot of work, and progress is slow, and technical difficulty is big, and as gate valve, scraping bevel must not have a bit inclination, and surfacing is smooth, and it is qualified not have leakage side through hydraulic pressure, and difficulty is very big as can be known.
The purpose of this utility model just provides a kind of machinery that adopts and grinds, and progress is fast, and technical difficulty is little, valve grinding machine easy to use.
Solution of the present utility model is such: with the mill assembly is to link to each other with motor, and motor is to regulate suitable rotational speed by speed regulator, selects the mill assembly of different structure for use, selects suitable rotating speed, just can grind spool or valve seat.
The utility model has the advantages that simple in structurely, can adopt machinery to grind, progress is fast, and technical difficulty is little, and is easy to use.
Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is the structural representation of the utility model when making the spool grinder.
Accompanying drawing 2 is the utility model structural representations when making portable valve seat grinder.
Accompanying drawing 3 is first kind of structural representation of the mill assembly 2 of spool grinder.
Accompanying drawing 4 is second kind of structural representation of the mill assembly 2 of spool grinder.
The utility model mill assembly 2 is to link to each other with motor 1, and motor 1 is to regulate suitable rotational speed by speed regulator 11.
When adopting the novel spool grinder of making shown in the accompanying drawing 1 of this reality, mill assembly 2 can be made the structure shown in the accompanying drawing 3, and mill assembly 2 has the pressure ring 16 of outer ring projection, pushes down emery cloth 5 at pressure ring 16, and mill assembly 2 links to each other with motor 1.Also can make the structure shown in the accompanying drawing 4, have the hole that adapts with spool in the centre of mill assembly 2.So that the safety valve spool is ground.For making things convenient for practical operation, present embodiment is to adopt two mill assemblies 2, and each mill assembly 2 links to each other with motor 1 by transmission device, and described transmission device is to adopt belt transmission.Described motor is to adopt buncher, carries out speed governing by speed regulator 11.
When the utility model was made portable valve seat grinder, as shown in Figure 2, described mill assembly 2 was one, directly links to each other with the output shaft of motor 1, and mill assembly 2 has base plate 14, and the mill assembly of different size can grind different valve seats.Mill assembly 2 is to be fastened on the swing arm 12 with nut 8.
In the accompanying drawing, the 1st, motor, the 2nd, mill assembly, the 3rd, workbench, 4 mills, 5 emery cloths, 6 mills The dish intermediate plate, the 7th, nut, the 8th, valve seat, the 9th, abradant surface, the 10th, articulated joint, the 11st, speed regulator, the 12nd, Swing arm, the 13rd, chuck, the 14th, base plate, the 15th, spool, the 16th, pressure ring, the 17th, spool.
