Preferably, the positive cubic position of the ring flange is provided with groove.Raising limiting plate is connected steady with ring flange
It is qualitative, it is easy to the position restriction to valve body.
Preferably, the groove bottom is provided with the nut consistent with the screw thread on set screw.By nut to positioning
Screw is fixed, and avoids limiting plate from being pitched with ring flange junction.
Preferably, the inside diameter of the limiting plate is less than the inside diameter of bonnet.Shadow when avoiding spacing Board position excessively upper
Ring the use of bonnet.
Preferably, the bonnet is provided with spacing collar with valve body junction.Avoid limiting plate tight with bonnet by spacing collar
Close connection, is unfavorable for valve operation.
Preferably, the spacing collar and the tapered connection of valve body.Improve spacing collar and limiting plate and bonnet are limited to limiting plate
The distance between.
In the utility model, valve body is fixedly connected with bonnet, be inserted in successively in the outside of valve body spacing collar, limiting plate,
Telescoping tube and ring flange, by spacing collar fixed cover in bonnet and valve body junction, avoid influenceing bonnet when spacing Board position is excessively upper
Use, telescoping tube is arranged between limiting plate and ring flange, and the length of telescoping tube is passed through method by limiting plate by set screw
Blue disk is fixed, and effectively prevents telescoping tube from departing from valve body, ensures the safety of valve body institute connecting line.The limit telescopic butterfly valve, structure
Simply, low cost, effectively prevent telescoping tube from departing from valve body, ensure the safety of valve body institute connecting line.
