All-dimensional spraying device for corrosion-resistant pneumatic control valve membrane cover

Abstract

The invention discloses an all-dimensional spraying device for a corrosion-resistant pneumatic control valve membrane cover. The all-dimensional spraying device comprises a transmission table, a mechanical arm, a membrane cover body and a spraying assembly, wherein the spraying assembly is arranged between the transmission table and the mechanical arm and is used for carrying out electrostatic spraying work on the membrane cover body, the spraying assembly comprises a rotating pipe, and a material pipe and an electric heating rod are fixedly arranged on the inner wall of the rotating pipe. According to the all-dimensional spraying device, an electric wire in a rotating rod is connected to a positive electrode, at the moment, raw materials with negative charges are gathered towards the surface of the membrane cover body, so that waste caused by splashing of the raw materials is effectively avoided; and meanwhile, the interiors of a second spiral coil and a first spiral coil are connected to a power supply, so that magnetic fields are formed on the surfaces of the first spiral coil and the second spiral coil, then the raw materials can move towards the surface of the membrane cover body under the action of an electric field and the magnetic fields, and the situation that the sprayed raw materials splash and influence the body health of workers can be prevented while the uniform spraying effect is achieved.

Description

technical field [0001] The invention relates to the technical field of spraying of a membrane cover of a pneumatic regulating valve, in particular to a corrosion-resistant pneumatic regulating valve membrane cover all-round spraying device. Background technique [0002] The pneumatic control valve uses compressed air as the power source, uses the cylinder as the actuator, and drives the valve with the help of electric valve positioners, converters, solenoid valves, position valves and other accessories to realize switch or proportional adjustment. It is an important part of the pneumatic control valve. The membrane cover is generally made of conductive metal materials. In order to make the membrane cover corrosion-resistant, it is generally necessary to spray its surface with a spraying device. [0003] However, when the prior art is actually used, it cannot be sprayed in all directions, and the sprayed raw materials are easy to float into the air and then affect the health ...
