Description

T-shaped flange butterfly valve

Technical Field

The utility model belongs to the technical field of the equipment part, especially, relate to a T type flange butterfly valve.

Background

A butterfly valve, also called a flap valve, is a regulating valve with simple structure, and can be used for the on-off control of low-pressure pipeline media, namely a valve which is opened and closed by rotating around a valve shaft, wherein a closing member (a valve clack or a butterfly plate) is a disk.

The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like. The pipe mainly plays a role in cutting off and throttling. The butterfly valve opening and closing piece is a disc-shaped butterfly plate and rotates around the axis of the butterfly plate in the valve body, so that the opening and closing or adjusting purpose is achieved. The butterfly valve is a valve which uses a disc type opening and closing piece to rotate back and forth by about 90 degrees to open, close or adjust the medium flow. The butterfly valve has the advantages of simple structure, small volume, light weight, less material consumption, small installation size, small driving moment, simple and convenient operation and rapidness, and simultaneously has good flow regulation function and sealing closing characteristic, thereby being one of the fastest valve varieties developed in the last ten years. Butterfly valves are widely used. The variety and number of uses thereof are still continuously expanding and are developing toward high temperature, high pressure, large caliber, high sealing property, long life, excellent regulation property, and one-valve multi-function. The reliability and other performance indexes of the composite material reach higher levels. The butterfly valve has a small flow resistance when fully opened. When the valve is opened between 15 degrees and 70 degrees, sensitive flow control can be carried out, so that the application of the butterfly valve is very common in the field of large-caliber adjustment.

Because of the wiping properties of the movement of the butterfly plate of the butterfly valve, most butterfly valves are used with media having suspended solid particles. Depending on the strength of the seal, it can also be used for powdered and granular media. The butterfly valve is suitable for flow regulation. Since the pressure loss of the butterfly valve in the pipe is relatively large, about three times that of the gate valve, when selecting the butterfly valve, the influence of the pressure loss on the pipeline system should be fully considered, and the strength of the butterfly plate bearing the pressure of the pipeline medium when closing should be considered. In addition, the operating temperature constraints to which the elastomeric valve seat material is subjected at high temperatures must also be considered. The butterfly valve has a small structural length and overall height, is fast in opening and closing speed, and has good fluid control characteristics. The structure principle of the butterfly valve is most suitable for manufacturing a large-diameter valve. When a butterfly valve is required for flow control applications, it is important to properly select the size and type of butterfly valve to operate properly and efficiently. In general, in throttling, regulation and control and slurry media, the structure length is required to be short, the opening and closing speed is high, and the low-pressure cut-off (the pressure difference is small), so that a butterfly valve is recommended to be selected. Butterfly valves are used when the two-position adjustment, reduced diameter channels, low noise, cavitation and vaporization, small leakage to the atmosphere, and abrasive media are available. Throttling regulation under special working conditions, or working conditions of strict sealing, serious abrasion, low temperature (deep cooling) and the like.

Most of existing flange butterfly valves in the market are of a single-pass pipe type, electric control multi-channel butterfly valves are few, T-shaped pipelines are common in modern pipeline system construction, and a multi-channel butterfly valve is needed when the butterfly valve is a suitable valve under individual conditions, so that a T-shaped flange butterfly valve is provided.
