Abstract
The invention relates to an eccentric pneumatic butterfly valve, in particular to an eccentric pneumatic butterfly valve which is applied in systems of metallurgy, electric power, petrochemical engineering, municipal administration, gas, water supply and drainage and the like, and belongs to the technical field of pneumatic butterfly valves. The eccentric pneumatic butterfly valve comprises a valve body, a valve plate, a valve rod and a pneumatic executor; a flowing hole is formed in the valve body, the valve plate capable of sealing the flowing hole is arranged at the flowing hole, the valve rod is connected to the valve plate, and the center line of the valve rod deviates from the center line of the flowing hole; one end of the valve rod is connected with the driving end of the pneumatic executor, and the pneumatic executor drives the valve rod to rotate. The eccentric pneumatic butterfly valve has the advantages that the structure is simple, compact and reasonable, the strength of the valve body is improved, friction of a sealing ring is reduced, and the service life is prolonged; high flowing capacity, low flowing resistance and high temperature and high pressure resistance are achieved.
Description
Technical field
The present invention relates to a kind of bias Pneumatic butterfly valve, specifically apply in metallurgy, electric power, petrochemical industry, municipal administration, coal
Eccentric Pneumatic butterfly valve in the system such as 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 adjusts and cuts off, butterfly valve structure is simple, small volume, light weight, only by a few part
Composition, simple to operate, its structural principle is suitable for making large bore valves, has good metering characteristics simultaneously, therefore exists
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 passes through two valve rod mounting seats to realize
With the connection of valve plate, when using, valve rod drives valve plate to rotate.After life-time service, valve rod is susceptible to flexible deformation, leads
Eccentric-butterfly-valve is caused can not normally to use.
Content of the invention
It is an object of the invention to overcoming above-mentioned weak point, thus providing a kind of bias Pneumatic butterfly valve, improve valve body
Intensity, reduce sealing ring friction, improve service life.
The technical scheme providing according to the present invention, eccentric Pneumatic butterfly valve includes valve body, valve plate, valve rod and pneumatic actuator,
It is characterized in that: valve body is provided with opening, at opening, be provided with the valve plate that can seal opening, valve plate connects valve rod, valve
The centrage of bar deviates the position of center line of opening；Valve rod one end connects the drive end of pneumatic actuator, by pneumatic actuator
Valve rod is driven to rotate.
Further, valve rod and valve body, valve plate junction are provided with sealing ring.
Further, it is provided with bearing between valve rod and valve body.
Compared with the prior art the present invention has the advantage that
Present configuration is simple, compact, reasonable, improves the intensity of valve body, reduces the friction of sealing ring, improves and use the longevity
Life；Negotiability is big, and flow resistance is little, high-temperature-resistant high-pressure-resistant.

Specific embodiment
The embodiment combining in accompanying drawing is further described by the present invention below:
As shown in Figure 1 and 2, the invention mainly comprises valve body 1, valve plate 2, valve rod 3 and pneumatic actuator 4, valve body 1 is provided with circulation
Hole, is provided with the valve plate 2 that can seal opening at opening.Valve rod 3 is connected on valve plate 2, the centrage of valve rod 3 deviates opening
Position of center line.
Valve rod 3 one end connect pneumatic actuator 4 drive end, drive valve rod 3 to rotate by pneumatic actuator 4, valve rod 3 turn
The dynamic rotation driving valve plate 2, thus realize being turned on and off of opening.
It is provided with bearing 5, bearing 5 reduces the abrasion of valve rod 3 between described valve rod 3 and valve body 1.
Described valve rod 3 and valve body, valve plate 2 junction are provided with sealing ring 6, improve sealing by sealing ring 6.
The pneumatic actuator work band ovable valve stem of the present invention rotates, and reaches the function of valve plate opening and closing.The present invention ties
Structure is simple, compact, reasonable, improves the intensity of valve body, reduces the friction of sealing ring, improves service life；Negotiability is big,
Flow resistance is little, high-temperature-resistant high-pressure-resistant.
