Abstract

The invention discloses a double-seat three-eccentric V-shaped hard sealing ball valve. The double-seat three-eccentric V-shaped hard sealing ball valve comprises a valve body and a valve body cap, wherein a valve rod is arranged in a longitudinal hole of the valve body, valve plates are arranged in transverse valve openings in the valve body and the valve body cap, fixing plates are connected below the valve plates, valve seats are connected among the valve plates, the valve body and the valve body cap, and a sealing surface is formed between the valve plates and the valve seats. During use,the double-seat three-eccentric V-shaped hard sealing ball valve is adopted, compared with a common ball valve, the valve plates can be separated from the valve seats when the valve plates are opened,and the use torque is greatly reduced; and compared with a common three-eccentric butterfly valve, due to the existence of the front valve plate and the rear valve plate, the use pressure differencecan be greatly increased. In addition, V-shaped notches exist, so that the accurate adjustment of the valve can be met under the small opening degree. Due to the unique structural design, except the valve body and the valve plates, other parts can be universal with the standard ball valve and can be completely interchanged, and the parts are convenient to maintain and replace.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a double-seat, triple-eccentric, V-shaped hard-sealed ball valve. Background technique [0002] Ball valves and butterfly valves are the two most used valves, but their shortcomings are also obvious and cannot be solved. Ball valves are now used to increase the actuator torque to achieve the purpose of control. Existing ball valves all play a switching role and cannot be adjusted accurately. Butterfly valves can withstand very small pressure differences due to their inherent characteristics. The purpose of the present invention is to overcome the shortcomings of the existing products and provide a valve with a wide range of use, which can not only reduce the valve torque, but also increase the pressure difference of the valve, and can also meet the precise adjustment of small openings. Contents of the invention [0003] The object of the present invention is to provide a...
