Description
Technical Field
The utility model relates to the technical field of valves, specifically a novel triple offset 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. With the application of the synthetic rubber for preventing chemical corrosion to the butterfly valve, the performance of the butterfly valve is improved. The synthetic rubber has the characteristics of corrosion resistance, erosion resistance, stable size, good rebound resilience, easiness in forming, low cost and the like, and synthetic rubbers with different properties can be selected according to different use requirements so as to meet the use working condition of the butterfly valve. Because Polytetrafluoroethylene (PTFE) has strong corrosion resistance, stable performance, difficult aging, low friction coefficient, easy forming and stable size, and can improve the comprehensive performance by filling and adding proper materials, the butterfly valve sealing material with better strength and lower friction coefficient is obtained, and the limitation of synthetic rubber is overcome, thus the high polymer material represented by polytetrafluoroethylene and the filling modified material thereof are widely applied to the butterfly valve, thereby further improving the performance of the butterfly valve, and manufacturing the butterfly valve with wider temperature and pressure ranges, reliable sealing performance and longer service life. In order to meet the use requirements of industrial applications such as high and low temperature, strong erosion, long service life and the like, the metal sealing butterfly valve is greatly developed. With the application of high temperature, low temperature, strong corrosion, strong erosion and high strength alloy materials in butterfly valves, the metal sealing butterfly valve is widely applied in the industrial fields of high and low temperature, strong erosion, long service life and the like, and the butterfly valve with large caliber (9-750 mm), high pressure (42.0MPa) and wide temperature range (-196-606 ℃) appears, so that the technology of the butterfly valve reaches a brand new level. The butterfly valve has a small flow resistance when fully opened. When the valve is opened between about 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 is divided into: (1) the butterfly valve comprises a central sealing butterfly valve, (2) a single eccentric sealing butterfly valve, (3) a double eccentric sealing butterfly valve, and (4) a triple eccentric sealing butterfly valve.
The prior art has the following defects or problems:
1. after the three-eccentric butterfly valve used in the current market is assembled, most valve plates are protected by plastic pipes and adhesive tapes in the process of packaging finished products, and the three-eccentric butterfly valve is inconvenient to use;
2. after the valve plate of the three-eccentric butterfly valve is used for a long time, the bearing force of the valve plate is reduced, so that the valve plate is easy to deform, and the use of the valve plate is influenced.
