Abstract
The utility model relates to a cutting-off ball valve which can be provided with an explosion-proof valve control mechanism and an explosion-proof position signal returning device. An elastic clamping ring is arranged between the end part of a sealing seat and the ball valve body. The other end of the sealing seat is provided with an O-shaped sealing ring to form a floating type sealing seat, so that the ball valve body has the functions of friction and shearing as well as the effect of sealing reinforcement. The utility model can be applied to the situation that the medium viscosity is great and fine fibers contain suspended particles, and the situation with easy adhesion.
Description
The utility model relates to the instrument and meter for automation valve field, a kind of cut-out ball valve that is used for Explosion-proof valve control mechanism and explosion-proof position signal recoverable capsule specifically, but and execute-in-place, be widely used in papermaking, food, chemical industry, oil, metallurgy, sewage treatment occasion, finish the unlatching of system's medium or the function of closing.
At present general used cut-out ball valve, circulation medium is had viscosity or has fiber, can cause closing leakage, can't will have the media erase of fiber outside sealing surface when closing or opening, sealing surface is to adopt single hard sealing simultaneously, or single soft seal, it is above-mentioned that both all can bring certain shortcoming in actual use to valve.
The purpose of this utility model provides and can be applicable to that dielectric viscosity is big, and fibril contains a kind of explosion-proof pneumatic V-type cut-out ball valve of the band suspended particulate and the occasion that easily bonds, and the valve rod running torque is bigger simultaneously.
For finishing the technological scheme that above-mentioned purpose is taked: the entry end of valve body is provided with sealing seat, establishes snap ring between the end of sealing seat and the valve body, and the other end of sealing seat is established " O " shape seal ring and formed.Sealing seat is floating structure.
The utility model is wiped the examination scissors action because the motion of spheroid between valve seat has, guarantee big and have fibril and have proper functioning under the operating mode situation of suspended particulate in dielectric viscosity, because sealing surface adopts firmly, the double seal of soft combination is so sealing has reliability preferably simultaneously.
The utility model is embodiment described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1, the utility model integral body is made up of actuator and valve body two-part, actuator is by cylinder 7, adjustable cover is to axle 8, guide pin bushing 9, piston 10, gear shaft 11 is formed, the worm gear that the valve rod 6 of valve body part connects in the Worm gear case, by worm gear connection gear axle 11, gear shaft 11 rotating band ovable valve stems 6, valve rod 6 lower ends connect V-arrangement valve plate 3, the lower end of valve plate 3 connects minor axis 1, it is characterized in that valve body 2 is provided with the movable hard sealing seat 4 of stainless steel, establish snap ring 5 between the end of sealing seat 4 and the valve body 2, the other end of sealing seat 4 is established " O " shape seal ring 12, constitutes the valve seat floating structure, because valve plate 3 is a v-shaped structure, so for valve seat has the examination of wiping shear action, the setting of round section joint ring 12 simultaneously, the seal action of reinforcement valve seat.
