Heatable ball valve

Abstract

The invention discloses a heatable ball valve. The heatable ball valve comprises a valve body, wherein a plurality of outlets are formed in the peripheral side of the valve body, two sides of the valve body are provided with heating layers correspondingly, one sides, far away from the valve body, of the heating layers are provided with fixing frames, and the fixing frames are arranged on the valve body through countersunk bolts; the heating layers comprise sealing heat transfer layers, the sealing heat transfer layers are arranged on the outer wall of the valve body, one sides of the sealing heat transfer layers are provided with heating wire placement boxes, heating wires are arranged in the heating wire placement boxes, heat dissipation holes are formed in one sides, close to the sealing heat transfer layers, of the heating wire placement boxes, temperature sensors are arranged on the inner side walls of the heating wire placement boxes, the temperature sensors are electrically connected with temperature controllers, the temperature controllers are electrically connected with control switches, heat preservation layers are arranged on one sides of the heating wire placement boxes, and the fixing frames are arranged on the outer sides of the heat preservation layers. According to the heatable ball valve, the problems that most traditional valve bodies are heated in a resistance heating mode, and the heating mode is high in maintenance and repair cost, unsafe in heating, long in preheating time, time-consuming and labor-consuming are solved.

Description

technical field [0001] The invention belongs to the technical field of vacuum high-temperature conveying devices, and in particular relates to a heatable ball valve. Background technique [0002] Ball valve (ball valve), the opening and closing part (ball) is driven by the valve stem, and the valve body that rotates around the axis of the ball valve. It can also be used for the regulation and control of fluids, among which the hard-sealed V-shaped ball valve has a strong shear force between its V-shaped ball core and the metal valve seat of surfacing welding carbide, and is especially suitable for fibers and tiny solid particles. etc. medium. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the medium on the pipeline, but also close any channel and connect the other two channels. This type of valve body should generally be installed horizontally in the pipeline. According to the driving mode, the ball valve ...
