Abstract
The invention discloses a grinding tool of a threaded flange sealing surface. The grinding tool comprises a handle, a grinding body and a connecting rod. The handle is fixedly connected with the upper end of the connecting rod. The grinding body is in a big-end-up inverted circular truncated cone shape. An internal thread perpendicular to the upper end face is arranged in the center of the upper end face of the grinding body. An external thread is arranged at the lower end of the connecting rod and engaged with the internal thread on the grinding body. The side face of the grinding body serves as a grinding face used for grinding the threaded flange sealing surface. Due to the inclination angle of the grinding face, it is guaranteed that the grinding face can grind the threaded flange sealing surface. The hardness value of the grinding body is larger than that of a threaded flange. According to the grinding tool of the threaded flange sealing surface, grinding time can be shortened, and the sealing quality of the ground threaded flange sealing surface can be guaranteed.
Description
Technical field
The present invention relates to the grinding tool of screwed flange sealing surface.
Background technology
Screwed flange is sealing device conventional on a kind of high-tension apparatus, but when infrequently using when the idleness of equipment, the sealing surface of screwed flange just there will be corrosion pit, sealing effectiveness can be affected, now we need to carry out milled processed to sealing surface, when corrosion pit hole is more shallow, grind can handle well easily by traditional facing-up mode, but when corrosion pit hole is deep, use traditional facing-up mode not only length consuming time, and the airtight quality of screwed flange sealing surface after grinding can not be guaranteed.
Summary of the invention
The object of the invention is: provide one to reduce milling time, the grinding tool of the screwed flange sealing surface of the airtight quality of the screwed flange sealing surface after grinding can be ensured again.
For achieving the above object, the technical solution adopted in the present invention is: the grinding tool of screwed flange sealing surface, comprise: handle, grinding body, connecting rod, described handle is fixedly connected with connecting rod upper end, described grinding body is lower little large reversed round bench shaped, and the internal thread be provided with on the center, upper surface of grinding body perpendicular to upper surface, described connecting rod lower end is provided with external screw thread, described external screw thread engages with the internal thread on grinding body, the side of grinding body is used to the abradant surface grinding screwed flange sealing surface, the angle of inclination of described abradant surface ensures that abradant surface can grind screwed flange sealing surface, the hardness number of described grinding body is higher than the hardness number of screwed flange.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, the center of grinding body upper surface is provided with the cylinder exceeding upper surface, and the described internal thread perpendicular to upper surface is arranged on this cylinder.Use this structure can reduce to grind the weight of body, the reach of internal thread can be ensured again simultaneously, make internal thread and external screw thread have sufficient connecting length.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, the externally threaded reach of described connecting rod is not less than the reach of internal thread.This structure is to enable external screw thread and internal thread fully engage, and prevents engagement insufficient and causes loosening.
Further, the grinding tool of aforesaid screwed flange sealing surface, wherein, described handle is connected with connecting rod is vertical.This structure is used to be to ensure that handle is parallel with grinding body upper surface, making operating personnel pass easily through the balance of joystick to balance grinding body in process of lapping, reach grinding effect better.
The invention has the beneficial effects as follows: use the grinding tool of screwed flange sealing surface to reduce milling time, the airtight quality of the screwed flange sealing surface after grinding can be ensured again.
Accompanying drawing explanation
Fig. 1 is the upward view of the grinding tool of screwed flange sealing surface of the present invention.
Fig. 2 is the sectional view of the grinding tool of screwed flange sealing surface of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing and preferred embodiment, technical solutions according to the invention are described in further detail.
As Fig. 1, shown in Fig. 2, the grinding tool of screwed flange sealing surface of the present invention comprises: handle 1, grinding body 2, connecting rod 3, described handle 1 is connected with the upper end of connecting rod 3, and ensure that connecting rod 3 is perpendicular to handle 1, described connecting rod 3 lower end is provided with external screw thread 31, described grinding body 2 is lower little large reversed round bench shapeds, and the cylinder 22 exceeding upper surface is provided with on the center of the upper surface 21 of grinding body 2, and the internal thread 221 be provided with on this cylinder 22 perpendicular to upper surface 21, described internal thread 221 engages with the external screw thread 31 of connecting rod 3 lower end, can fully engage with the internal thread 221 on grinding body 2 to make the external screw thread 31 of connecting rod 3 lower end, prevent engagement insufficient and cause loosening, the reach of external screw thread 31 is processed be longer than the reach of internal thread 221 by we, the side of grinding body 2 is used to the abradant surface 23 grinding screwed flange sealing surface, the angle of inclination of described abradant surface 23 ensures that abradant surface 23 can grind screwed flange sealing surface, grind the hardness number of hardness number higher than screwed flange of body 2.
In practical operation, handle 1 and connecting rod 3 are welded to connect, sub-assembly handle 1 and connecting rod 3 are formed by connecting again is engaged with the internal thread 221 on grinding body 2 by the external screw thread 31 on connecting rod 3, make it and grind body 2 and be connected, because handle 1 vertical connecting 3, grinding body 2 is connected with connecting rod 3 by internal thread 221, also vertical with connecting rod 3, so handle 1 is in parallel position with grinding body 2.After grinding tool installs by operating personnel, the screwed flange sealing surface having corrosion pit coats abrasive pastes, the lower surface 24 of the grinding tool of screwed flange sealing surface of the present invention is placed on the gas thread place of screwed flange, abradant surface 23 is made to be resisted against on sealing surface, then operating personnel hold handle 1 and rotate, and the sealing surface that now abradant surface 23 starts double thread flange grinds.Because the own wt of grinding body 2 just can make abradant surface 23 pairs of sealing surfaces produce downward pressure, like this, operating personnel only need use less power just can complete grinding, when operating personnel use low-force turning handle 1, grinding tool is more easily operated by operating personnel, so just can ensure the stability of grinding tool in process of lapping, improve grinding efficiency, in turn ensure that the grinding effect of grinding body 2 pairs of sealing surfaces simultaneously.
Use the advantage of the grinding tool of screwed flange sealing surface of the present invention to be: can milling time be reduced, the airtight quality of the screwed flange sealing surface after grinding can be ensured again.
