The upper sealing surface of the valve seat is damaged due to sand and stone particles and the like, so that when the sealing surface is required to be polished, the sealing surface of the valve body can be polished without detaching the valve body, and the repair time of the sealing surface can be shortened, as shown in figures 1-2, the utility model provides a polishing device for the sealing surface. The sealing surface sharpening device comprises a cutter bar 1, a pressing adjusting sleeve 3 and a positioning assembly 4.

The first end of the cutter bar 1 is fixedly provided with a trimming knife 2, and the first end of the cutter bar 1 can be inserted into the valve body through the valve bar hole; the pressing adjusting sleeve 3 is provided with external threads, the pressing adjusting sleeve 3 can be in threaded connection with the valve rod hole, the pressing adjusting sleeve 3 is sleeved on the cutter rod 1, and the pressing adjusting sleeve 3 is abutted to the grinding cutter 2; locating component 4 with compress tightly the adjusting collar 3 spiro union, locating component 4 can with the valve body butt to the limited relative position who compresses tightly adjusting collar 3 and valve body.

When the valve body is used, the first end of the cutter bar 1 is inserted into the valve body, the pressing adjusting sleeve 3 is installed, the relative position of the pressing adjusting sleeve 3 and the valve body is limited through the positioning assembly 4, so that the abutting of the grinding cutter 2 and a sealing surface to be ground is guaranteed, then the cutter bar 1 is rotated, the cutter bar 1 drives the grinding cutter 2 to rotate, and the grinding of the sealing surface is achieved. Through the mode, the sealing surface of the valve body can be polished without detaching the valve body, and the repair time of the sealing surface can be shortened.

Further, a cutter hole 11 is formed in the first end of the cutter rod 1, and the sharpening cutter 2 penetrates through the cutter hole 11. Through the guide holes, the repairing cutters 2 can be conveniently inserted, and therefore the repairing cutters 2 can be conveniently installed and detached.

Further, a threaded hole communicated with the cutter hole 11 is formed in the first end of the cutter bar 1, a fastening piece 12 is in threaded connection with the threaded hole, and the fastening piece 12 abuts against the trimming cutter 2. Specifically, in the present embodiment, the fastener 12 is a screw, and after the sharpening blade 2 is inserted into the blade hole 11 and the position is adjusted, the fastener 12 is installed, and the fastener 12 abuts against the sharpening blade 2, thereby fixing the sharpening blade 2. When the knife is disassembled, the repairing knife 2 can be disassembled only by unscrewing the fastener 12. Through foretell mode, be convenient for repair the installation and the dismantlement of sword 2.

Further, a screw 13 is fixedly provided at the second end of the tool shank 1. Through the arrangement of the screwing part 13, when the sealing surface is polished, a tool can be used for acting on the screwing part 13, so that the cutter bar 1 is driven to rotate. The torque can be increased by using the tool, so that the labor intensity in the grinding process is reduced.

Further, in the present embodiment, the screw part 13 has a quadrangular square head shape. Specifically, the screw 13 may be clamped with a wrench, and then the rotation of the tool bar 1 may be achieved by rotating the wrench. The square head shape is adopted, so that the wrench can clamp the screwing part 13 conveniently, and the relative rotation between the rotary wrench and the screwing part 13 can not be generated.

Further, the tool bar 1 and the screwing part 13 are of an integrated structure. By designing the cutter bar 1 and the screwing part 13 as an integrated structure, the strength of the connection of the screwing part 13 and the cutter bar 1 can be ensured, and the manufacture is convenient.

Further, the positioning assembly 4 comprises a clamping ring 41 and a compression nut 42, the clamping ring 41 and the compression nut 42 are both in threaded connection with the compression adjusting sleeve 3, the clamping ring 41 can be abutted against the valve body, and the compression nut 42 is used for pressing the clamping ring 41 onto the valve body. Because threaded connection can have the clearance between the screw, after compressing tightly adjusting collar 3 and valve body spiro union and butt on repair sword 2, because the existence in screw thread clearance leads to the butt power of being used in on repair sword 2 less to lead to the coping operation to go on smoothly. Through the arrangement of the clamping ring 41 and the compression nut 42, the relative position between the compression adjusting sleeve 3 and the valve body can be limited, so that the influence caused by thread clearance is eliminated, sufficient abutting force applied to the grinding cutter 2 is guaranteed, and the grinding work is guaranteed to be carried out smoothly.

Further, a gasket 5 is arranged between the pressing adjusting sleeve 3 and the sharpening cutter 2, the gasket 5 is sleeved on the cutter rod 1, and the pressing adjusting sleeve 3 is abutted to the sharpening cutter 2 through the gasket 5. When carrying out the coping to sealed face, the guide arm can compress tightly adjusting sleeve 3 relatively and rotate to lead to repairing to grind 2 and compress tightly adjusting sleeve 3 between relative rotation, lead to compressing tightly adjusting sleeve 3 and can be worn and torn. By arranging the gasket 5, the gasket 5 is worn instead of the compression adjusting sleeve 3, and only the gasket 5 needs to be replaced after the gasket 5 is worn.

Further, one end of the pressing adjustment sleeve 3 is fixedly provided with a screw annular protrusion 31. Specifically, in the present embodiment, the screwing annular projection 31 is a regular hexagon, which facilitates the adjustment of the pressure applied to the sharpening blade 2 by rotating the pressing adjustment sleeve 3 with a wrench.

Further, the screwing ring-shaped protrusion 31 and the pressing adjustment sleeve 3 are of an integrated structure. Through the arrangement, the connection strength of the screwing annular protrusion 31 and the pressing adjusting sleeve 3 can be ensured, so that the pressing adjusting sleeve 3 can be driven to rotate by rotating and screwing the screwing annular protrusion 31.

The use method of the sealing surface coping device comprises the following steps:

firstly, wear to establish the knife 2 on the first end of cutter arbor 1, and utilize fastener 12 to fix, then insert the first end of cutter arbor 1 in the valve body through the valve pole hole, then install gland nut 42 and snap ring 41 on compressing tightly adjusting sleeve 3, compress tightly adjusting sleeve 3 screw in the valve body, adjust the length of screw in, make compressing tightly adjusting sleeve 3 exert pressure on knife 2 through packing ring 5, make knife 2 butt on sealed face, utilize snap ring 41 and gland nut 42 to inject and compress tightly adjusting sleeve 3 the position on the valve body, twist the portion 13 of twisting with the spanner card on cutter arbor 1, rotate cutter arbor 1, cutter arbor 1 drives knife 2 and rotates, scrape sealed face. The length of the pressing adjusting sleeve 3 screwed into the valve body is adjusted according to the scraping condition, the scraping thickness is increased until the scraping of the sealing surface is smooth, and the sealing requirement is met.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments.
