Abstract
The utility model discloses a grinding device of a large diameter high pressure stop valve. The grinding device of the large diameter high pressure stop valve is characterized in that the grinding device is of a circular truncated cone shape, the angle between the outer side and the inner side of a grinding tool is the same as that of the valve, and a grinding valve seat on the outer side and a valve head on the inner side are adopted. By grinding, excess metal on the surfaces of the valve head and the valve seat is cut and polished, two sealing faces achieve the same angle, the sealing faces are repaired, the sealing effect is recovered, and the inner leakage problem of the valve is solved. The grinding device of the large diameter high pressure stop valve can effectively improve the maintenance efficiency of the high pressure stop valve, greatly saves the maintenance cost, and is easy to implement and obvious in effect.
Description
Technical field
The utility model relates to a kind of high-pressure stop lapping device, relates in particular to a kind of major diameter high-pressure stop lapping device that is applicable to chemical industry.
Background technology
In chemical process, because the interior leakage problem of high-pressure stop valve occurs often, and maintenance difficulty comparatively.The interior leakage of valve mainly is that it is the main cause of interior leakage that there is the gap in the composition surface because washing away of medium causes valve head to cooperate with valve seat to go wrong.
The utility model content
The purpose of this utility model is exactly in order to address the above problem, and a kind of major diameter high-pressure stop valve lapping device is provided, and it is sunken that it has the interior burst of eliminating stop valve, guarantees the stable of technique, improves maintenance efficiency, reduces to greatest extent the advantage of maintenance cost.
To achieve these goals, the utility model adopts following technical scheme:
A kind of major diameter high-pressure stop valve lapping device, it is a hollow circular table milling tool, the milling tool inwall matches with the valve head that is polished valve, and the milling tool outer wall cooperates with the valve seat that is polished valve, is provided with grinding tool and rotating machinery locating hole at an end of milling tool.
The beneficial effects of the utility model:
This utility model device can improve the maintenance efficiency of high-pressure stop valve effectively, has greatly saved maintenance cost.And implement simplyr, effect is remarkable.
Description of drawings
Fig. 1 is major diameter high-pressure stop valve lapping device schematic diagram;
Fig. 2 is that major diameter high-pressure stop valve lapping device grinds the valve head schematic diagram;
Fig. 3 is that major diameter high-pressure stop valve lapping device grinds the valve seat schematic diagram.
Wherein, 1. grinding tool and rotating machinery locating hole, 2. mould inner surface abrasion site, 3. valve head sealing position, 4. grinding tool outside abrasion site, 5. valve sealing position.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment.
For the interior burst of eliminating stop valve falls into, guarantee the stable of technique, the stop valve of interior leakage can be keeped in repair, use specific purpose tool, the sealing surface of stop valve is ground, eliminate the purpose of leaking in the stop valve thereby reach.Thereby the raising maintenance efficiency reduces maintenance cost to greatest extent.
A kind of major diameter high-pressure stop valve lapping device, it is a hollow circular table milling tool, the milling tool inwall matches with the valve head that is polished valve, and the milling tool outer wall cooperates with the valve seat that is polished valve, is provided with grinding tool and rotating machinery locating hole 1 at an end of milling tool.
Shown in Fig. 2,3, by high pressure valve valve seat, the valve head opened and inspect are surveyed and drawn, can make the milling tool of truncated conical shape by oneself, the outside of milling tool, inboard are processed into and the valve equal angular, utilize grinding tool outside abrasion site 4 to grind valve seat, utilize grinding tool internal grinding position 2 to grind valve head sealing position 3.Valve sealing position 5 is corresponding to a position of grinding tool outside abrasion site 4, by grinding valve head, valve base surface excess metal are cut, polish, it is identical that two sealing surfaces reach angle, repairs sealing surface, recover sealing effectiveness, solve the interior leakage problem of valve.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of the present utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
