Description
Technical field
The utility model is related to a kind of eccentric Pneumatic butterfly valve, specifically applies in metallurgy, electric power, petrochemical industry, city
Eccentric Pneumatic butterfly valve in the systems such as political affairs, coal gas and plumbing, belongs to Pneumatic butterfly valve technical field.
Background technology
Eccentric Pneumatic butterfly valve is widely used in the systems such as metallurgy, electric power, petrochemical industry, municipal administration, coal gas and plumbing, is
The optimum device that Large Diameter Pipeline big flow is adjusted and cut off, butterfly valve structure is simple, small volume, light weight, only by a few part
Composition, simple to operate, its structural principle is adapted to make large bore valves, while there are good metering characteristics, therefore
It is widely used in the industries such as petrochemical industry, metallurgical steel-making, water process, electric power.
The valve rod mounting seat of traditional eccentric-butterfly-valve is symmetricly set on valve plate, and valve rod is realized through two valve rod mounting seats
With the connection of valve plate, when in use, valve rod drives valve plate to rotate.After long-term use, flexible deformation easily occurs for valve rod, leads
Eccentric-butterfly-valve is caused normally to use.
The content of the invention
The purpose of this utility model is to overcome above-mentioned weak point, so as to provide a kind of eccentric Pneumatic butterfly valve, improved
The intensity of valve body, reduces the friction of sealing ring, improves service life.
The technical scheme provided according to the utility model, eccentric Pneumatic butterfly valve includes valve body, valve plate, valve rod and pneumatic execution
Device, it is characterized in that：Valve body is provided with to be provided with to seal at opening, opening connects valve rod on the valve plate of opening, valve plate,
The center line of valve rod deviates the position of center line of opening；Valve rod one end connects the drive end of pneumatic actuator, by pneumatic execution
Device driving valve rod is rotated.
Further, valve rod and valve body, valve plate junction are provided with sealing ring.
Further, bearing is provided between valve rod and valve body.
Compared with the prior art the utility model has advantages below：
The utility model is simple in construction, compact, reasonable, improves the intensity of valve body, reduces the friction of sealing ring, improves
Service life；Negotiability is big, and flow resistance is small, high-temperature-resistant high-pressure-resistant.
Brief description of the drawings
Fig. 1 is the utility model shape assumption diagram.
Fig. 2 is the half-sectional structure chart of the utility model.
Description of reference numerals：1- valve bodies, 2- valve plates, 3- valve rods, 4- pneumatic actuators, 5- bearings, 6- sealing rings.
Embodiment
The utility model will be further described with reference to the embodiment in accompanying drawing below：
As shown in Figure 1 and 2, the utility model mainly includes on valve body 1, valve plate 2, valve rod 3 and pneumatic actuator 4, valve body 1
The valve plate 2 of opening can be sealed by being provided with provided with opening, at opening.Valve rod 3 is connected on valve plate 2, the center line of valve rod 3 is inclined
From the position of center line of opening.
The one end of valve rod 3 connects the drive end of pneumatic actuator 4, drives valve rod 3 to rotate by pneumatic actuator 4, turn of valve rod 3
The rotation of dynamic drive valve plate 2, so as to realize being turned on and off for opening.
Bearing 5 is provided between the valve rod 3 and valve body 1, bearing 5 reduces the abrasion of valve rod 3.
The valve rod 3 and valve body, the junction of valve plate 2 are provided with sealing ring 6, and sealing is improved by sealing ring 6.
Pneumatic actuator work band ovable valve stem of the present utility model is rotated, and reaches the function that valve plate is opened and closed.This reality
It is simple, compact, reasonable with new structure, the intensity of valve body is improved, the friction of sealing ring is reduced, improves service life；Stream
Logical ability is big, and flow resistance is small, high-temperature-resistant high-pressure-resistant.
