Abstract

The invention relates to the field of valve production, and discloses a painting device for a valve handwheel. The painting device comprises a paint groove; a rack is arranged on the paint groove; a rack is slidably connected onto the rack; a small gear is meshed with the rack; a cross rod is rotatably connected to the rack; a fixed position is arranged on the cross rod; the fixed position is sleeved with an elastic inflation barrel; a vertical pipe is arranged on the rack; a piston which is in clearance fit with the vertical pipe is arranged in the vertical pipe; the inside of the vertical pipe is divided into an upper pipeline and a lower pipeline by the piston; a connection rod is arranged in the upper pipeline; two ends of the connection rods are separately hinged to the rack and the piston; an inflation pipe is connected between a lower end of the lower pipeline and the elastic inflation barrel; a paint inlet pipe is connected with the paint groove; a rotary shaft is rotatably connected into the paint groove; a turbine is fixedly connected to one end of the rotary shaft and is located at a connection opening of the paint inlet pipe and the paint groove; and an elastic belt isconnected between the other end of the rotary shaft and the cross rod. By adopting the painting device, while the handwheel is painted, a through hole of the handwheel is prevented from being paintedwith paint; and machining efficiency of the handwheel is improved.

Description

Technical field

[0001] The invention relates to the field of valve production and processing, in particular to a painting device for a valve hand wheel. Background technique

[0002] The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, stabilization, diversion or overflow and pressure relief. The main structure of the valve includes the valve body, the valve core, the valve stem and the handwheel. The valve has a T-shaped structure as a whole, and the valve body has an "I"-shaped structure, and the valve body includes an intermediate pipe and a connection at both ends of the intermediate pipe. Flange, the flange is provided with multiple positioning holes evenly distributed in the circumferential direction, and the handwheel is like figure 1 As shown, it includes a wheel ring and a connecting column in the wheel ring. The center of the connecting column is provided with a perforation for...
