A turbine flange butterfly valve

Abstract

The invention relates to a turbine flange butterfly valve, which comprises a main solid mechanism, a valve body and an auxiliary solid mechanism. The lower end of the main solid mechanism is connected to the existing ground through sliding fit, and the upper end of the main solid mechanism is connected with a valve. Body, the front end of the valve body is provided with an auxiliary fastening mechanism, the present invention adopts the design concept of multiple clamping to install the turbine flange butterfly valve, the combination and separation between the main fastening mechanism and the auxiliary fastening mechanism can reduce the two in a single valve body Occupancy time during the installation process can shorten the interval between continuous installation of the valve body, thereby improving the overall work efficiency. At the same time, the auxiliary fixing mechanism can also adapt to the change of the connection structure size, thereby expanding the overall clamping application range of the device. .

Description

technical field [0001] The invention relates to the field of butterfly valve installation, in particular to a turbine flange butterfly valve. Background technique [0002] Butterfly valve refers to a kind of valve whose closing part (disc or butterfly plate) is a disc and rotates around the valve shaft to open and close. It mainly plays the role of cutting off and throttling on the pipeline. Flanged flap valve) is a kind of regulating valve with simple structure, and can also be used for on-off control of low-pressure pipeline medium. Turbine flanged butterfly valve generally adopts triple eccentric multi-level metal hard sealing structure, which is suitable for production furnace, gas, natural gas, It is used to adjust and cut off the flow of the medium on the pipelines that transport various corrosive and non-corrosive fluid media in engineering systems such as liquefied petroleum gas, city gas, hot and cold air, chemical smelting, power generation and environmental protec...

AI Technical Summary

Problems solved by technology

[0003] 1. Because the clamping structure is too simple or the clamping range of the clamping structure is small, the overall stability of the valve body is low, and the valve body is prone to shaking. At the same time, the adaptability of the clamping mechanism to changes in the size of the valve body lower;

[0004] 2. The valve body in the clamped state is easier to deviate from the vertical direction, that is, the valve body is in an inclined state, and the inclined state is more likely to lead to the firmness of the connection between the valve body and the connecting structure, which in turn affects the overall sealing degree
