Description
Technical field
This utility model is related to valve technology field, specially a kind of double stub shaft butterfly valve.
Background technology
Butterfly valve structure is simple, small volume, lightweight, is only made up of a few parts.And it is fast by need to being only rotated by 90 °
Speed is opened and closed, simple to operate, while the valve has good fluid handling properties.The butterfly plate of butterfly valve is installed on the diameter side of pipeline
To.In butterfly valve body cylindrical channel, disc butterfly plate is rotated around axis, and the anglec of rotation is between 0-90 degree, rotates to
When 90 degree, valve then board full-gear.When flange butterfly is in full open position, butterfly plate thickness be when medium flows through valve body only
One resistance, therefore by the pressure drop very little produced by the valve, therefore has preferable metering characteristics.
In existing butterfly valve, if during misoperation, it may appear that valve rod departs from dish plate phenomenon, unlatching, the closing of valve are affected,
Must shut down and be keeped in repair, hinder production, increase cost.
Utility model content
The purpose of this utility model is to provide a kind of double stub shaft butterfly valve, to solve the valve rod proposed in above-mentioned background technology
Depart from dish plate, affect the unlatching of valve, the problem that closes.
For achieving the above object, this utility model provides following technical scheme：A kind of double stub shaft butterfly valve, including valve body, dish
Plate, upper valve rod, handwheel, actuating device, motor, upper platen, O-ring, lower valve rod, handle, pressing disc and support, the valve body
Inner chamber is inlaid with dish plate, and dish plate is connected by upper valve rod with actuating device, and the handwheel is arranged on the left side of actuating device,
And be connected by connecting rod between handwheel and actuating device, the motor is fixedly connected on the right side of actuating device, and motor
It is connected by rotating shaft between actuating device, the support is fixedly connected on the bottom of actuating device, and the lower bottom part of support
Platen is provided with, the upper platen is fixedly connected on the side of valve body, and the opposite side of valve body is symmetrically installed with pressing disc, institute
The outside that O-ring is uniformly embedded in dish plate is stated, the handle is located between the bottom of valve body, and handle and dish plate and passes through lower valve rod
It is connected.
Preferably, the inner chamber of the upper platen and pressing disc is inlaid with sealing gasket.
Preferably, the handle is rotatable device, and the rotating range of handle is 0-90 degree.
Preferably, the O-ring is elastic seal ring.
Preferably, the upper valve rod and lower valve rod are made using bearing chromium steel material.
Compared with prior art, the beneficial effects of the utility model are：The double stub shaft butterfly valve is provided with upper valve rod and lower valve rod,
Upper valve rod can be used with lower valve rod, it is to avoid during single stem dropping cannot controlled valve, be provided with resilient, elastomeric, make up dish plate with
Gap between valve body, better tightness, using the valve rod of bearing chromium steel material, valve rod hardness is big, and corrosion resistance is strong, using the longevity
Life is longer.
