Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of butterfly valve plates, in particular to a hard alloy valve plate. Background Art
[0002] The butterfly valve, also known as the flap valve, is a simple regulating valve that can be used for the on-off control of low-pressure pipeline media. The butterfly valve refers to a valve whose closing part (valve disc or butterfly plate) is a disc that rotates around the valve axis to achieve opening and closing. The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal and radioactive media. It mainly plays a role of cutting off and throttling on the pipeline. The opening and closing part of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis in the valve body to achieve the purpose of opening, closing or regulating.
[0003] The butterfly valve controls the flow of fluid through the internal valve plate. However, the existing butterfly valve plate is smooth on both the front and rear sides when in use, and no additional resistance is generated when the fluid passes through it, so that the initial velocity of the fluid in the butterfly valve is increased too quickly, which is inconvenient for the staff to use. At the same time, the sealing ring of the outer ring of the existing butterfly valve plate is directly sleeved on the outer ring of the valve plate, and the connection strength between the valve plate and the valve plate is poor, which is easy to fall off and cause damage to the butterfly valve, making it inconvenient to use.
