Abstract

The invention discloses a fluoroplastic lining butterfly valve. The fluoroplastic lining butterfly valve comprises a valve body, an upper valve shaft and a valve cover, wherein the top end of the valve body is fixedly connected to the upper valve shaft, the top end of the upper valve shaft is movably connected to the valve cover, an alarm interface is in embedded connection to the middle part of one end of the valve body, one end of the alarm interface is fixedly connected to a leakproof alarm, one end of the top end of the leakproof alarm is electrically connected to an alarm lamp, a valve seat is fixedly connected in the valve body, a metal valve clack is fixedly connected in the valve seat, and the metal valve clack is of better resistance to fall and wear resistance, so that the sealing effect of a fluoroplastic butterfly valve main body is guaranteed fully. When a trigger device triggers the alarm lamp to start alarming, an operator can find the leak problem of the fluoroplastic butterfly valve immediately through the alarm lamp and exclude related accidents favorably, so that the safety of the fluoroplastic butterfly valve in the using process is improved well. The fluoroplastic lining butterfly valve is applied and has a wide development prospect in the future.

Description

technical field [0001] The invention relates to the technical field of fluoroplastics, in particular to a fluoroplastic-lined butterfly valve. Background technique [0002] In heavy chemical industry, large chemical fertilizer, petroleum petrochemical, iron and steel smelting and other occasions where corrosive fluid media are transported, metal valves are obviously unusable because they will be corroded. Therefore, in such occasions, valves with fluoroplastic lining are usually required. [0003] However, the existing fluoroplastic-lined valves such as fluoroplastic-lined butterfly valves, due to their structure, can still meet the sealing requirements for small-diameter fluoroplastic-lined butterfly valves, but for large-diameter fluoroplastic-lined butterfly valves, the butterfly plate must be processed However, the roughness of the processed sealing surface is too large, the repair is difficult, the interchangeability is low, and the possibility of problems with large-di...
