Depression forms groove, and groove extends radially outwardly along cavity, and the bottom surface at groove both ends offers first through hole；The one of the valve rod
End is connected with spheroid, and the other end is connected after sequentially passing through the cavity of valve neck, mounting platform with actuator, is set in the cavity of valve neck
There is filler, gland is provided with filler；The gland includes cylinder and the location-plate of fixed cylinder upper end, and the both ends of location-plate are opened
Provided with the second through hole；On valve rod, and in the cavity of cavity valve neck, the lower end of cylinder supports in filler the barrel jacket
Upper end, location-plate are fastened in groove, and the upper surface of location-plate, cylinder be not higher than mounting platform upper surface, each first
Through hole is corresponding with second through hole, and bolt passes through corresponding first through hole, the second through hole to be connected with nut thread, passes through spiral shell
Bolt connects as one gland and mounting platform.
Set gland replace compress filler with nut or jump ring by way of, have hole among gland, just valve rod from
Passed in hole, corrected under gland cylinder and push down filler, first through hole is designed at gland location-plate both ends, coordinates on ball valve body
The hole position of gland designs the second through hole, is connected as one gland and mounting platform by bolt, tightening spiral shell mesh makes whole gland
Filler is pushed down, is sealed.During ball valve use, as revealed, only need to tighten gland both ends spiral shell mesh just plays sealing
Effect, practicality simple to operate are easy-maintaining.
By opening up groove in mounting platform upper surface, directly can be sealed by lock nut, prevent valve rod with
The leakage that valve seal position occurs, it is not necessary to dismantle actuator, facilitate onsite application.Need to dismantle actuator in the prior art
Could lock nut.
Further improve, the valve rod, which is set, is arranged with pairing combination butterfly spring, and pairing combination butterfly spring is located at cylinder
Between filler.By setting pairing to combine butterfly spring, compensating action can be played when occurring tiny leakage at valve rod, discharges it
The deformation of pretension compresses filler again, improves sealing effectiveness.
Further improve, second through hole is shoulder hole, and the larger one end in aperture is located at close to the side of actuator.Make spiral shell
Bolt head is located in the larger hole in shoulder hole aperture, ensures that bolt head is not higher than mounting platform upper surface, prevents from installing with actuator
When interfere.
Further improve, the mounting platform is flange, and actuator is connected by bolt with mounting platform, is easy to dismount.
Further improve, the valve body, valve neck, the casting integrated formation of flange, Stability Analysis of Structures, intensity is high.
Compared with prior art, the beneficial effects of the invention are as follows：
Set gland replace compress filler with nut or jump ring by way of, have hole among gland, just valve rod from
Passed in hole, corrected under gland cylinder and push down filler, first through hole is designed at gland location-plate both ends, coordinates on ball valve body
The hole position of gland designs the second through hole, is connected as one gland and mounting platform by bolt, tightening spiral shell mesh makes whole gland
Filler is pushed down, is sealed.During ball valve use, as revealed, only need to tighten gland both ends spiral shell mesh just plays sealing
Effect, practicality simple to operate are easy-maintaining.
By opening up groove in mounting platform upper surface, directly can be sealed by lock nut, prevent valve rod with
The leakage that valve seal position occurs, it is not necessary to dismantle actuator, facilitate onsite application.Need to dismantle actuator in the prior art
Could lock nut.
