It is further improved, second through-hole is stepped 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 stepped hole aperture, ensures that bolt head not higher than mounting platform upper surface, prevents from installing with actuator
When interfere.
It is further improved, the mounting platform is flange, and actuator is connect by bolt with mounting platform, easy to disassemble.
It is further improved, the valve body, valve neck, the casting integrated formation of flange, stable structure, intensity is high.
Compared with prior art, the beneficial effects of the utility model are：
Set gland replace compress filler with nut or clamp spring by way of, have hole among gland, just valve rod from
It is pierced by hole, is corrected under gland cylinder and push down filler, first through hole is designed at gland positioning plate both ends, coordinates on ball valve body
Gland and mounting platform, are connected as one, tightening spiral shell mesh makes entire gland by the second through-hole of hole position design of gland by bolt
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 easy to operate are easy-maintaining.
By opening up groove in mounting platform upper surface, can be directly sealed by lock nut, prevent valve rod with
The leakage that valve seal position occurs does not need to dismounting actuator, facilitates onsite application.It needs to dismantle actuator in the prior art
It could lock nut.
