A rotary device for a threaded valve seat

Abstract

The invention discloses a rotating device of a threaded valve seat. The rotating device comprises a fixing device, a position clamping device and a rotating device body. The fixing device is provided with a locating transverse plate, moving fork grooves, a rotating hole, fixing bolts and bolt nuts; the position clamping device is provided with square sleeves, clamping blocks, threaded holes and set screws; the rotating device body is provided with a position clamping sleeve bar, a rotating bar, a support force bar, a handheld handle, an upper rotary circular base plate and a lower rotary circular base plate. The rotating device is simple in structure and easy to operate; unnecessary danger of installation personnel cannot be caused because of the anti-deviation fixing transverse plate and the two vertically-spaced rotary parallel bars added according to the structure of a product, installation can be achieved by two persons when a stress application bar is used, redundant staff are not needed to keep balance of the stress application bar, and trouble and labor are saved.

Description

technical field [0001] The invention relates to a rotating device for a threaded valve seat, in particular to a fixed anti-deflection rotating device. Background technique [0002] In the valve industry, once the hole diameter of the general threaded valve seat is higher than DN300, it is difficult to tighten, because some of the lower ends are sealed, and some are sealed by glue, which is laborious and time-consuming for disassembly and replacement, and sometimes the product will be discarded. , the existing installation workshop may have a simple rotating device, which is to put a long rod directly on the block. During installation, since the direction of rotation is not fixed, it is easy to cause the force to be unbalanced during the force process. If it is empty, it is easy to cause the installer to be injured, especially when the afterburner is used and multiple people are installed together. Contents of the invention [0003] The object of the present invention is t...
