Description

Technical Field

[0001] The utility model relates to the technical field of valve turbine boxes, in particular to a valve turbine box which is easy to disassemble. Background Art

[0002] A valve turbine housing is a transmission device used on industrial valves, primarily for adjusting valve opening and closing angles, flow, and pressure. The valve turbine housing is compact and primarily consists of two or more small housings, which contain components such as bearings and gears. The main bearing supports the rotation of the gears and main shaft. The bearing at the bottom of the housing is typically a self-lubricating sliding bearing that fits snugly against the shaft, capable of withstanding heavy axial loads and preventing rotation and twisting. Existing valve turbine housings are typically installed using a flange and several bolts and nuts. Disassembly requires unscrewing several nuts, which is cumbersome and time-consuming. Utility Model Content

[0009] Beneficial effects

[0010] The utility model provides a valve turbine box that is easy to disassemble and has the following beneficial effects:

[0011] The valve turbine box which is easy to disassemble is operated on several fixing mechanisms during installation through the mounting plate, the mounting hole and the fixing mechanism. First, the mounting rod is inserted into the hole of the pipeline system and the mounting hole on the mounting plate, and then the limit sleeve is pushed and the bent limit rod is inserted into the first insertion hole, the second insertion hole and the limit sleeve. Then, the fastening nut is tightened on the fixing screw so that the elastic force of the telescopic spring always tightens the mounting rod, thereby making the valve turbine box firmly installed on the pipeline system and realizing the installation of the valve turbine box. When disassembling, it is only necessary to pull out the bent limit rod and the mounting rod in turn to remove the valve turbine box from the pipeline system. The operation is simple, convenient and labor-saving. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The working principles and beneficial effects of the above embodiments.

[0024] When in use, for installation, place the valve turbine box body 1 in the required installation position of the pipeline system, and align the installation hole 4 on the installation plate 3 with the hole of the installation part on the pipeline system, insert the installation rod 513 into the hole of the installation part on the pipeline system and the installation hole 4, until the end of the installation rod 513 is in the fixed frame 501, rotate the installation rod 513 to align the second hole 514 with the first hole 507 on the slider 506, and at the same time press the limit sleeve 510 to make the telescopic rod 502 contract and the telescopic spring 511 be compressed, and one end of the bending limit rod 504 is passed through the first hole 507 and the second hole 514 in turn, and the other end of the bending limit rod 504 is inserted into the limit sleeve 510. Under the elastic force of the telescopic spring 511, the limit sleeve 510 drives the bending limit rod 504 to move, and the installation rod 513 is installed. The cam 513 is then pulled so that the head of the mounting rod 513 is pressed against the mounting portion of the pipe system, and the mounting portion is pressed against the mounting plate 3. A longer and more elastic telescopic spring 511 is used so that the telescopic spring 511 is still in a compressed state at this time. Then the fastening nut 512 is tightened on the fixing screw 503, so that the mounting rod 513 is restricted to the current position. Since the telescopic spring 511 is always in a compressed state, the elastic force of the telescopic spring 511 always tightens the mounting rod 513. By setting up multiple fixing mechanisms 5, it is possible to ensure that the valve turbine box body 1 is firmly installed on the pipe system, thereby realizing the installation of the valve turbine box. When disassembly is required, the bent limit rod 504 is pulled outward, and then the mounting rod 513 is pulled outward, so that the valve turbine box body 1 can be separated from the pipe system. The operation is simple and convenient.
