Description
Technical field
The utility model relates to a kind of valve, and more particularly, it relates to a kind of lining fluorine Fixed ball valve.
Background technique
Modern word under ball valve, refers to making open-shut device with the spheroid of manhole, and spheroid rotates with valve rod, to realize the valve of switching motion.The main feature of ball valve is compact structure own, and easy operating and maintenance are applicable to the general work media such as water, solvent, acid and rock gas, but also are applicable to the severe medium of operating conditions, as oxygen, hydrogen peroxide, methane and ethene etc.Ball-valve structure is simple, volume is little, lightweight.Closely reliable, the seal face materials of ball valve is widely used plastics, good airproof performance at present, in vacuum system, is also widely used.Easy to operate, open and close rapidly, from standard-sized sheet to complete shut-down, need only half-twist, be convenient to remote control.Easy to maintenance, ball-valve structure is simple, and seal ring is all generally movable, and dismounting and change is all more convenient.When standard-sized sheet or full cut-off, the sealing surface of spheroid and valve seat and medium isolation, when medium passes through, can not cause the erosion of valve sealing face.Applied widely, latus rectum from little to several millimeter, arrives greatly several meters, from high vacuum to high pressure, all can apply.The structure of ball valve is similar to stopcock, and it is ball valve valve also person.It forms sealing pair by a spheroid and two valve seats (seal ring).The most frequently used material of valve seat is polytetrafluoroethylplastic plastic.In various valves, the fluid resistance of ball valve is minimum, and it has advantages of again, and switch is rapid, good airproof performance, because becoming a class valve with fastest developing speed.Its Applicable scope is very wide: working pressure is (pressure has reached 40 MPas) from high vacuum to high pressure, and operating temperature is-253～+ 150 ℃, and maximum caliber has reached 3000 millimeters.The major defect of ball valve is that operating temperature is not high.People are developing the sealing ring materials such as carbon, graphite, to improve the serviceability temperature of ball valve.The working principle of ball valve is to make valve unimpeded or inaccessible by rotation valve ball.Ball valve switch is light, and volume is little, can make very heavy caliber, and sealing is reliable, simple in structure, easy to maintenance, and sealing surface and the sphere closed state of being everlasting is difficult by medium erosion, in every profession and trade, is widely used.
Existing ball valve generally comprises valve body, valve rod, valve seat and valve ball.Valve body offers liquid chunnel and passage is installed, liquid chunnel and installation passage intersect, valve ball is arranged on liquid chunnel and the intersection of passage is installed and center offers diameter and the suitable through hole of liquid chunnel diameter, valve rod is located at and is installed in passage and be fixedly connected with valve ball, valve seat is located between valve ball and valve body and valve ball can rotate relative to valve seat, valve body comprises that left end cap, valve body and right end cap three parts form
when mounted valve, need installations that combine of three parts, trouble is installed, and directly contact between each constituent elements of valve and liquid by valve, be easily corroded, thus the working life of shortening valve.
Model utility content
