Valve surface treatment device and treatment process

The invention relates to the technical field of valve machining, in particular to a valve surface treatment device which comprises a device body, a control panel is installed on the outer wall of one side of the device body, and an air blower is installed on the outer wall of one side of the device body. The device has the beneficial effects that firstly, four positioning rods slide to the outer wall of the side close to a supporting rod, then a valve is in lap joint with a fixing rod, then the positioning rods are moved to make close contact with the inner wall of the valve and then are fixed through nuts, and then a handle is pulled to push a sealing plate to control a fixing assembly to slide into a device body; the drying assembly is started through the control panel to blow hot air into the device body, and the electrostatic tungsten filament plate and the negative electrode grid mesh are started, so that dust in the device body is adsorbed and collected through the negative electrode grid mesh after bei
