Description
Technical field:
The utility model relates to valve body milling apparatus field, is specifically related to a kind of fluid in-out end flange sealing surface special grinder of gate valve body.
Background technology:
Gate valve is an opening and closing element flashboard, and valve inner medium channel is straight-through, and medium is in line flowing, and flow resistance is little.With stop valve Comparatively speaking, no matter be out or close, ram movement direction is all perpendicular with media flow direction, therefore open and close time more laborsaving.
In the production process of gate valve body, due to the reason such as mould and die accuracy or operation, can there is hackly phenomenon in the flange sealing surface of valve body fluid in-out end.This directly will affect the connection sealing of valve body and fluid inlet and outlet piping, easily causes the leakage of fluid.In order to avoid the generation of this phenomenon, need that grinding is carried out to flange sealing surface and make its flat smooth.And the valve body grinder used at present exist valve body fixing not firm, grinding precision is low and speed slow and the shortcoming such as fragile valve body structure.
Utility model content:
Technical problem to be solved in the utility model is to provide a kind of grinding precision high and the fluid in-out end flange sealing surface special grinder of fireballing gate valve body.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
A kind of fluid in-out end flange sealing surface special grinder of gate valve body, comprise frame, be located at the grinding mechanism that fixed mechanism in frame and symmetry are located at fixed mechanism two ends, described fixed mechanism is made up of two U-shaped fixed mounts be arranged in parallel and the L bracket being located at fixed mount side, the first cylinder is provided with above fixed mount, described first cylinder upper end is fixed on support, lower end is provided with pressing plate, described grinding mechanism is by guide rail, be arranged on the lapping device on guide rail, the second cylinder be connected with lapping device rear end forms, described lapping device comprises gripper shoe, motor, rotating disk and grinding head, described disk axes is provided with rotating shaft, motor drives rotating shaft to rotate by chain drive, described grinding head is arranged on disk axes.
The longitudinal center line of described rotating disk and the longitudinal center line of flange are on same straight line.
Described grinding head is cylindrical structural, and diameter is equal with flange outer diameter.
Described pressing plate is in square, and the length of side is greater than the external diameter of valve body and valve gap connectivity port.
Operation principle of the present utility model:
Be fixed on fixed mount first by valve body to be ground before grinding into and out of end, then the first cylinder band dynamic pressure plate moves downward the connectivity port making pressing plate tightly push down valve body and valve gap, thus is fixedly secured by whole valve body; Second cylinder promotion gripper shoe is moved along guide rail to the fluid inlet of valve body and the port of export subsequently, until grinding head is close to flange sealing surface, open machine operation switch again, motor drives turntable rotation by chain drive, thus grinding head is rotated with the grinding carrying out flange sealing surface; Grinding terminates rear motor and quits work, and the second cylinder drives grinding head to leave valve body, and the first cylinder moves upward and makes pressing plate leave valve body subsequently, is finally taken off by ground valve body.
The beneficial effects of the utility model are: structure is simple, reasonable in design, easy to operate, valve body firmly can not only be fixed up, avoid the damage causing valve body structure in process of lapping because of grinding vibration, and the grinding of fluid inlet and outlet end flange sealing surface can be realized simultaneously, be of value to and increase work efficiency.
