Description
Technical field
The utility model relates to valve maintenance technology, particularly relates to a kind of technology of grinding device for sealing surface of valve base.
Background technology
Valve in power station is after certain service time, due to the difference in contact frictions a large amount of between spool and valve seat and two component materials, sealing surface of seat can produce certain wear phenomenon, this phenomenon can cause valve seal decline, control performance reduces, thus cause whole bypath system efficiency to reduce, negatively influencing is produced to whole electric power station system.Current solution of the above problems changes whole valve base part, and this solution cost is higher.
Utility model content
For the defect existed in above-mentioned prior art, technical problem to be solved in the utility model is to provide a kind of grinding device for sealing surface of valve base that can extend valve seat service life.
In order to solve the problems of the technologies described above, a kind of grinding device for sealing surface of valve base provided by the utility model, is characterized in that: comprise abrasive disk, interior pipe, outer tube, location-plate;
The bottom edge portion of described abrasive disk has chamfering, and this chamfered section lid is covered with rubber, and the bottom surface of abrasive disk is fixed with the grinding pressing plate for clamping rubber, and grinding pressing plate is removably fixed on abrasive disk;
Described interior pipe and outer tube are straight tube, spaced apartly vertically on the tube wall of interior pipe be provided with multiple pin-and-hole, the bottom of outer tube is provided with latch, and interior pipe and outer tube are socketed with movable fit system, and interfixed with coordinating of pin-and-hole by latch, interior pipe bottom by flange and abrasive disk coaxially affixed;
Described location-plate is arranged on outer tube by bearing, and the top of outer tube is fixed with a connector, and the bottom of outer tube has a spring base, outer tube is equipped with a Compress Spring, and the bottom of this Compress Spring props up spring base, and the top of Compress Spring props up location-plate.
Further, described location-plate offers multiple locating hole, each locating hole is divided into many groups, and each locating hole group is laid around the symmetrical interval of outer axial tube, lays with the spaced radial of each locating hole in group along outer tube.
The grinding device for sealing surface of valve base that the utility model provides, can easily carry out grinding to sealing surface of seat and safeguard, thus extend the service life of valve seat, greatly reduce the cost changing parts because of the prooving of valve seat.
