Description
Technical field
The present invention relates to sugar industry shut-off valve fields, are particularly suitable for the valve seat prosthetic appliance of shut-off valve, it is specific and
Speech is exactly a kind of cut-off valve seat repair machine.
Background technology
In sugar industry, it is widely applied to shut-off valve.Shut-off valve is mainly clapped by handwheel, valve rod, valve stem nut, valve deck, valve
(Valve disc), the part such as valve seat forms.Driving stem is rotated by handwheel, then drives valve bat to be moved in valve seat to adjust by valve rod
The flow of fluid.When Virgin sugar, each shut-off valve is often adjusted as needed, unavoidably brings abrasion and corrosion.After Virgin sugar,
It needs to overhaul shut-off valve, the contact surface that polish valve seat and valve are clapped keeps it more easy to attach, improves the tightness of shut-off valve, be more easy to
Precisely adjust the flow of liquid glucose.Existing processing mode, which relies primarily on, is manually polished with sand paper, and there are polishing unstable quality, beat
It is slow to grind speed, be easy to cause excessive polishing, shortens the service life of shut-off valve.

Speed motor passes through cable connection.There is slide cartridge to be sleeved on support post on electric machine support.Lead screw passes through the screw rod bushing on electric machine support.
Rocking arm is arranged at lead screw top.The transmission shaft of speed regulating motor is connect by universal turn with connecting rod.Connecting rod bottom is fixed with grinding head,
Grinding head outer surface is fixed with sand paper.Sand paper mesh number is between 300-1800 mesh.Suitable mesh number is selected according to valve seat corrosion degree
Sand paper.
Pedestal selects steel plate, thickness to be more than 10 millimeters.For safety, end the center of gravity of valve seat repair machine meta position in the base
It sets.Ending valve seat fixator selects U-type groove steel to make, and groove width is more than 200 millimeters.Shut-off valve fixator is equipped with geometrical clamp, uses
In fixed shut-off valve.Geometrical clamp can be fixed with ribbon button, can also be used arc-shaped newspaper binder, be fixed with bolt.
Support post can use cylindrical steel, can also be made of stainless steel tube.Slide cartridge is slidably connected with support post, lead screw
Coordinate with screw rod bushing, driving motor holder moves up and down.
Photoelectric sensor is fixedly connected with electric machine support, is moved up and down with electric machine support.Photoelectric sensor inductive head is aligned
Grinding head position, the main light intensity variation for incuding grinding head and ending valve seat frictional position.Its operation principle is:Shut-off valve
Metal luster after seat inner wall polishing, surface is more smooth, higher to the reflected intensity of light.Photoelectric sensor refers to equipped with 5
Show lamp, reflection light is stronger, and the bright quantity of indicator light is more, and brightness can also increase.Operating personnel can pass through viewing lamp
Variation, judge end valve seat polishing effect.Manipulate speed regulating motor.Photoelectric sensor can also turn the intensity of illumination sensed
It is changed to control signal, automatically adjusts motor speed.Intensity of illumination signal is higher, then reduce motor speed until stop motor, from
And reach automatic protection cut-off valve seat, it avoids excessively polishing, shortens shut-off valve service life.
Increase universal turn between transmission shaft and connecting rod, it is therefore an objective to make grinding head that there is certain flexibility, it can be better
It is polished to shut-off valve inner wall.For safety, before motor does not stop, grinding head cannot be removed to cut-off valve seat.
A kind of application method of cut-off valve seat repair machine:1, suitable mesh is selected according to the size of valve seat bore and corrosion degree
Several sand paper are fixed on grinding head;2, cut-off valve seat is fixed on cut-off valve seat fixator, and by shut-off valve to be polished
Seat center is aligned with grinding head;3, the height for adjusting electric machine support, grinding head is put into valve seat, motor is then started;4, lead to
Cross the depth of rocking arm adjustment grinding head;5, the indicator light on photoelectric sensor is observed, judges effect of polishing, then regulation motor speed
Degree and grinding head position, realize the reparation of valve seat.
In order to improve the repairing quality of the contact surface of valve seat, can utilize from thick to thin(Mesh number is ascending)Sand paper is repeatedly beaten
Mill.
The design for increasing universal turn between transmission shaft and connecting rod, the flexible contact solved between valve base inner wall and sand paper are asked
Topic, avoids the safety problem that valve seat is influenced to bring by motor centrifugal force, in turn avoids the impact being rigidly connected to motor.
By adopting the above-described technical solution, manual polishing is compared, have an advantageous effect in that:1, the labor of polishing is improved
Efficiency of movement reduces the labor intensity of worker;2, polishing quality is improved;3, the service life of shut-off valve is extended.
