Description

Technical Field

[0001] The utility model relates to the technical field of valve seat processing, in particular to a spraying device for valve seat processing. Background Art

[0002] The removable surface part in the valve is used to support the fully closed position of the valve core and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of the butterfly valve is very wide, and various rubber, plastic, and metal materials can be used as valve seat materials.

[0003] Spraying is a coating method that uses a spray gun or a disc atomizer to disperse the spray into uniform and fine droplets by pressure or centrifugal force and apply it to the surface of the object. It can be divided into air spray, airless spray, electrostatic spray and various derivative methods of the above basic spray forms, such as high-flow low-pressure atomization spray, thermal spray, automatic spray, multi-group spray, etc.

[0004] Most of the existing valve seat processing spraying equipment sprays the valve seat through a nozzle. This method has poor spraying effect and many dead corners. It is necessary to spray back and forth to avoid dead corners. At the same time, the bottom surface must be sprayed at the same time, which wastes paint. The spraying efficiency is low, the paint recovery efficiency is low, and the resource utilization rate is low.

[0005] After searching, the existing patent: a valve seat processing spraying equipment (application number: CN201922295750.7) includes a base and a spraying chamber, a spraying chamber is arranged on the top of the base, and a movable door and a placement door are respectively installed on the outer surface of the spraying chamber, and a feed port is penetrated through the outer surface of the movable door, and a motor is installed on the upper side of the spraying chamber. For the valve seat processing spraying equipment, the user opens the placement door, places multiple valve seats on the grid plate, and places them between two parallel limit rods, and then passes the pipe through the feed port to inject the paint into the paint chamber, and then turns on the liquid pump to extract the paint, and inputs the paint into the feed hose through the feed pipe, and then enters the spray pipe, and then is sprayed by the flat nozzle and the side nozzle, and the three surfaces of the valve seat are sprayed, and then the motor is turned on, and the motor drives the threaded rod to rotate, so that the sleeve is translated, and the spray pipe is driven to move back and forth to spray the valve seat. After one spraying, the valve seat is turned over and sprayed a second time, which improves the uniformity of the spraying.

[0006] Although the above patent drives the spray tube to move back and forth to spray the valve seat, after one spraying, the valve seat is turned over and sprayed a second time, which improves the uniformity of the spraying, but the paint inside the paint chamber of the device is prone to condensation during long-term use, which affects the spraying operation and is inconvenient for the user. Therefore, it is necessary to invent a spray device for valve seat processing to solve the above problems. Utility Model Content
