Abstract
The utility model relates to a rolling friction butterfly valve, which comprises a valve body, a valve rod, a butterfly plate, a bottom cover, a support, a transmission device, a sealing element and a mounting element, wherein the butterfly plate is fixedly connected with the middle part of the valve rod, the upper end of the valve rod is fixedly connected with the output shaft of the transmission device, and the transmission device is fixedly arranged on the support. The butterfly valve is characterized in that a circular arc-shaped recess is formed in the center of the bottom end surface of the valve rod, a recess is correspondingly formed on the bottom cover below the circular arc-shaped recess, and a bearing ball is arranged inside the recess. During the opening/closing process of the valve, the rolling friction is achieved between the valve rod and the upper end surface of the bottom cover through the bearing ball, so as to reduce the opening/closing friction force between the valve rod and the upper end surface of the bottom cover and the opening/closing torque of the valve and to reduce the valve size and the power required for the transmission device. The rolling friction butterfly valve has the advantages of labor-saving opening/closing operation, small volume, low cost and the like, and is applied to the fluid medium pipes in various industrial fields.
Description
Technical field
The utility model relates to a kind of valve, specifically about a kind of butterfly valve.
Background technique
The structural type of butterfly valve has plane sealing structure, two eccentric sealed structures, three eccentric sealed structures, no matter but be which kind of sealing configuration form, its structure generally all comprises valve body, valve rod, butterfly plate, bottom, support, transmission device and Sealing and assembling set, butterfly plate and the fixed installation of valve rod middle part, locate by divided ring between stem bottom and the valve body, its major defect is when valve rod rotates, be sliding friction between its bottom end and the bottom, frictional force is big, valve opening and closing moment is big, the power configuration of stem diameter and transmission device is bigger, causes the valve volume big, the cost height.
Summary of the invention
The purpose of this utility model is the shortcoming that exists at prior art, provides in a kind of opening-closing process between the valve rod and bottom frictional force little, opens and closes the rolling friction butterfly valve that moment is little, the valve volume is little, cost is low.
The technical solution of the utility model comprises valve body, valve rod, butterfly plate, bottom, support, transmission device and Sealing and assembling set, butterfly plate is connected with the fixed installation of valve rod middle part, fixedly connected with the transmission device output shaft in the valve rod upper end, transmission device is fixedly mounted on the support.Mainly be that valve rod bottom end center is shaped on the circular arc pit, be shaped on corresponding pit on the bottom below this circular arc pit, in this pit, spherical ball is set.
The utility model has the advantages that: in the valve opening and closing process, realize rolling friction by spherical ball between valve rod and the bottom upper-end surface, reduced between the two keying frictional force and the keying moment of valve, reduced the power configuration of valve rod size and transmission device, volume is little, cost is low.
