Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spraying equipment, in particular to a corrosion-resistant spraying equipment for steam turbine valve production. BACKGROUND

[0002] Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, flow guidance, anti-backflow, pressure stabilization, flow splitting, and overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the most complex self-control systems, with a wide variety of types and specifications. It should be noted that a large number of valves are required in the entire operation system of steam turbines, and because of the complex application scenarios of valves, it is necessary to spray corrosion-resistant paint on the valves during production to ensure their safe use.

[0003] During the spraying operation of the valve, the paint in the paint bucket is sucked in through the paint suction pipe of the spraying host, and then processed by the spraying host, and finally sprayed out through the spray gun on the paint spraying pipe. However, the existing single feed pipe scheme must be stopped, the pipe must be pulled out, the bucket must be replaced, and the material must be reinserted after one bucket of paint is used up, which causes the spraying operation to be interrupted, reduces the overall work efficiency, and frequent stoppage can cause defects in the connection of the sprayed coating. The original feed pipe filter cover is directly immersed in the paint, and as the liquid level drops, the filter cover is easily in contact with the impurities such as pigment particles and paint residue deposited at the bottom of the bucket, which can easily cause the filter cover to be blocked, thereby causing insufficient supply of material, unstable pressure of the spray gun, and even damage to the air jet pump body. In addition, when the paint suction pipe is disconnected from the paint at the moment, air is sucked in, causing quality defects such as bubbles and sagging during spraying. The paint is easily spilled during the process of pulling out the pipe and inserting the pipe, causing waste of raw materials and environmental and equipment pollution. At the same time, the original feed pipe is directly rubbed against the inner wall and bottom of the paint bucket, and after the paint dries, it is easily attached to the pipe wall, causing blockage and shortening the service life of the feed pipe.

[0028] The anti-corrosion spraying equipment for steam turbine valve production has the following advantages:

[0029] In the present application, by arranging the follow-up descending filter device, when the spraying machine is in use, the supply amount of paint can be effectively increased by arranging three paint buckets. When the spraying machine sucks the paint in the paint bucket through the paint suction pipe, the paint in the paint bucket enters the outer filter cover and is subjected to primary filtration. When the paint gradually decreases, the floating ring descends with the decrease of the liquid level, the floating ring moves downward to drive the closed sliding sleeve to move through the plurality of adapter frames, so that the closed sliding sleeve drives the closed folding cover to move downward, thereby gradually exposing the outer filter cover; the floating sleeve synchronously descends with the liquid level, and the sheath gradually moves downward, so that the filter cover is only exposed to the paint layer below the current liquid level, accurately adapts to the liquid level, avoids impurities from being sucked in, isolates the impurities at the bottom of the bucket from the source, greatly reduces the plugging probability of the pump body and the spray gun, reduces the equipment failure downtime, and can prevent air suction, thereby ensuring the stability of spraying.

[0030] Further, the filter cover is always in the effective area below the liquid level, and air will not be sucked in until the paint is basically exhausted, thereby ensuring that the pump body continuously and stably sucks the material, the spraying pressure is uniform, the valve coating thickness is consistent and there is no leakage, the product yield is improved, manual adjustment of the material inlet pipe position is not required, liquid level self-adaptive adjustment is realized, the monitoring and operation steps of the operator are reduced, and it is especially suitable for continuous production scenes of valve batch spraying, reduces labor costs, the filter cover is only exposed in a necessary range, the contact area and time with impurities in the paint are reduced, the filter cover pore blockage is delayed, the filter cover replacement and cleaning frequency are reduced, maintenance costs are saved, paint is fully utilized, waste is reduced, the remaining paint in the paint bucket can be maximized, the filter cover is completely exposed only when the liquid level is close to the bottom of the bucket, the remaining paint is not discarded in advance due to the fear of air suction due to impurities, and material loss is reduced.

[0031] Further, in the present application, through the setting of the uninterrupted feeding device, when the paint in one paint bucket is used up, the floating ring drives the pull-down support to move down, the pull-down support drives the plug-in blocking frame to disengage from the plug hole, so that the switching push-pull plate loses the limitation, and then under the reaction force of the switching spring, the switching spring drives the switching pull rod to move through the switching push-pull plate, the switching pull rod drives the switching closing plate to move, so that the switching closing plate closes one feeding hole and opens another feeding hole, realizes the suction of the paint in another paint bucket, and realizes the uninterrupted feeding, and ensures the continuous valve spraying work.

[0032] Further, in the present application, through the setting of the uninterrupted feeding device, when the paint in one paint bucket is used up, the floating ring drives the pull-down support to move down, the pull-down support drives the plug-in blocking frame to disengage from the plug hole, so that the switching push-pull plate loses the limitation, and then under the reaction force of the switching spring, the switching spring drives the switching pull rod to move through the switching push-pull plate, the switching pull rod drives the switching closing plate to move, so that the switching closing plate closes one feeding hole and opens another feeding hole, realizes the suction of the paint in another paint bucket, and realizes the uninterrupted feeding, and ensures the continuous valve spraying work.
