Background

At present, dust removing devices in industries such as electric power, steel, cement and the like all adopt a bag dust removing and electric dust removing process, wherein a quick switch dome valve connected with a pneumatic conveying system at the lower part of a hopper is a general fragile part. During the opening and closing process of the dome valve, the spherical valve core is abraded and air leakage can be caused by large material particles and impurities in the material. As the wear progresses, it eventually causes the conveyor system to shut down. How to ensure that the dome valve can be quickly detected on line and quickly overhauled to ensure that production is the most important work. Wherein, the spherical valve core and the sealing ring of the dome valve are common maintenance parts, and have higher repair value. The damage degree of the existing spherical valve element is detected by means of manual naked eyes, polishing and spraying after welding repair are judged by means of manual experience, an accurate measuring tool is not used, errors are large, and repair efficiency is low.

Detailed Description

To facilitate understanding of the present invention for those skilled in the art, embodiments of the present invention will be described below with reference to the accompanying drawings.

As shown in fig. 1-2, a dome valve overhaul device comprises a spherical wear length measuring scale 1 attached to the spherical surface of a dome valve, wherein scale marks 2 are arranged on the spherical wear length measuring scale 1. One effect of sphere abrasion length measurement chi 1 is used for carrying out the measurement of damaging regional length when the dome valve damages, and another effect is whether the detection of damaging of sphere is carried out with the sphere damage of dome valve sphere laminating be convenient for fix on it and damage degree of depth detection mechanism. To facilitate accurate measurement of the damaged area of the dome valve by the sphere wear length measuring ruler 1, the arc length of said sphere wear length measuring ruler 1 is 2/3 which is the maximum arc length of the sphere of the dome valve.

An auxiliary handle 3 is fixed on the spherical wear length measuring scale 1, and the auxiliary handle 3 and the spherical wear length measuring scale 1 are integrated. The auxiliary handle 3 and the spherical surface abrasion length measuring scale 1 are made of 304 stainless steel or aluminum alloy. The auxiliary handle 3 is of an arc-shaped structure, and a holding hole 4 is formed between the auxiliary handle 3 and the upper surface of the spherical wear length measuring scale 1. Is convenient for the carrying and the use of the maintainers.

One end of the spherical wear length measuring scale 1 is provided with a spherical damage and damage depth detection mechanism. The spherical surface damage and damage depth detection mechanism has one function of judging whether the spherical surface of the dome valve is damaged or not, and has the other function of acquiring data of the damage depth of the spherical surface of the dome valve.

In this embodiment, the spherical surface damage and damage depth detection mechanism is set as a dial indicator, the range of the dial indicator is 0-10mm, and the precision of the dial indicator is 0.1 mm. The dial indicator is fixedly connected with the spherical surface abrasion length measuring scale 1 through nut locking. The dial indicator comprises a dial 5, a measuring sleeve 6, a measuring rod and a measuring head 7, wherein the measuring head 7 is fixed at the lower end of the measuring rod, and the measuring rod can move up and down in the measuring sleeve 6. The measuring rod and the measuring head 7 of the dial indicator penetrate through the spherical surface abrasion length measuring scale 1, and the measuring head 7 protrudes out of the bottom surface of the spherical surface abrasion length measuring scale 1, so that the dome valve spherical surface can be conveniently judged to be damaged or not and the depth of a damaged area can be conveniently measured.

In specific maintenance process, sphere abrasion length measurement chi 1 one end is close sphere case edge, and one end sets up in the arc top department of calotte valve sphere, uses the arc top to rotate as the centre of a circle in the same direction as the pointer, can judge the sphere basic damage degree fast through the data of dial plate 5 display of percentage table.

If the spherical surface of the dome valve is seriously damaged as seen by naked eyes, a maintainer demarcates a damaged area, measures the damaged length through a spherical surface abrasion length measuring scale 1 and measures the depth of a damaged groove through a dial indicator, and then the repairing preparation is made. After the spherical surface of the dome valve is repaired, the flatness of the spherical surface can be further judged through the dome valve overhauling device so as to determine whether to continue repairing or grinding.

The above-mentioned embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
