The draw forms sealing and dustproof.
Preferably, the dust cover is cyclic annular soft rubber part, with the flexible seal of tube at be S type structure.
Compared with prior art, the utility model has the advantage that
One, angle compensation: the rotary body and body cavity and ball seat lid of large deflection Telescopic gate valve provided by the invention is provided
Between cooperated using spherical surface so that soft when leading to setting of ground when an earthquake occurs or because of soil property, rotary body and valve body
Between be relatively rotatable to each other, rotary body drives telescoping tube to deflect to appropriate angle immediately, provides biggish angle compensation.
Two, provide nose balance: anti-decylization of the invention is stuck in telescoping tube tail end and constitutes whole disconnecting prevention structure, and stretch pipe sleeve
It is located at a rotating body, can be relatively moved therebetween, to achieve the effect that nose balance.
Three, sealing effect is good, it is buried to be suitable for: squeezing ladder-shaped sealing ring using ball seat lid, reaches reliable and seal and flexure
Effect, and ring-shaped rubber dust cover is provided between ball seat lid and telescoping tube, also tighten with the angle of flexure or uphold patch jail and is stretching
On draw tube body, the sandy soil when gate valve is buried can be effectively prevent to enter inner cavity and influence the quality of pipeline medium.
Four, be easily installed disassembly, antidetonation: large deflection Telescopic gate valve provided by the invention is easily installed and dismantles, and can reduce
Labor intensity and maintenance cost, while there is good anti seismic efficiency.
