Embodiment Construction

[0017] A ball surface spray welding device for a ball valve, comprising a temperature control box, a reduction box, a tailstock, a spray gun, and a spray gun swing mechanism. The temperature control box includes an upper box body 6 and a lower box body 16. There is a spray gun door, and the upper box is covered on the lower box. There is a cavity for placing the sphere in the temperature control box. The elastic mandrel passes through the hole of the sphere and fits tightly with the sphere; the two ends of the mandrel pass through the reduction box respectively. The front end chuck and the tailstock are tightened; the spray gun is arranged outside the spray gun door 7, and the spray gun is connected with the spray gun swing mechanism; the swing mechanism includes a support plate 9 fixedly connected with the spray gun seat 18 of the spray gun 8, and one end of the support plate is sleeved on the support shaft 10, the other end of the support plate is fixedly connected with the g...

Abstract

The invention discloses a spray welding device for a ball body surface of a ball valve. A temperature control box comprises an upper box body and a lower box body, wherein a spray gun gate is arranged on the upper box body or the lower box body; the upper box body covers on the lower box body; a cavity for accommodating a ball body is formed in the temperature control box, an elastic-form mandrel passes through a hole of the ball body and is tightly matched with the ball body; the two ends of the mandrel prop against a tail frame by virtue of a chuck at the front end of a gearbox respectively; a spray gun is arranged on the outer side of the spray gun gate, the spray gun is connected with a spray gun swinging mechanism. The spray welding device is reasonable in structure, capable of enabling a sprayed piece to be integrally preheated in the temperature control box, high in heating efficiency, uniform in temperature, high in combination compactness and small in stress on a combined surface; the sprayed piece is integrally re-molten in the temperature control box, so that the surface of the sprayed piece is completely and sufficiently bonded in a metallurgical manner, and thus, a peel-off phenomenon is avoided; the spray welding device is cooled along with the box, so that the hardness of all surfaces is uniform, the processing efficiency is high and the quality is good. And besides, the working environment of the staff is improved, and the labor intensity of the staff is relieved.

Description

[0001] This application is a divisional application with application number: 201410426685.6, application date: 2014.8.27, and name "ball valve surface spray welding device". technical field [0002] The invention relates to a ball surface spray welding device for a ball valve. Background technique [0003] The existing sprayed coating on the ball surface of the ball valve is prone to peeling, has low processing efficiency, high work intensity and poor operating environment, and needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to provide a ball valve surface spray welding device with convenient operation, high processing efficiency, and good bonding performance of the sprayed layer on the ball surface of the ball valve. [0005] Technical solution of the present invention is: [0006] A ball surface spray welding device for a ball valve is characterized in that it includes a temperature control box, a reduction box, a...
