Description
Technical field
The utility model relates to a kind of valve technology field, in particular to a kind of super-pressure gate valve.
Background technique
Currently, common gate valve, only one interior main cutting big valve core of valve body executes machine when gate valve opens and closes
Structure drives big valve core to move up and down by valve rod.Occasion biggish for velocity of medium, is easy to produce super-pressure, due to big valve core
Front and back pressure cannot reasonably release, and the operational torque of valve rod increases, and spool is also not easy to open and close；And can not release
Super-pressure acts directly on big valve core, can cause the vibration of big valve core, and the vibration of one side big valve core can increase spool and close
It seals the abrasion of the sealing surface of valve seat, especially big valve core to be in close to when opening and closing position, pressure difference is very big, sealing surface wear
Even more serious, long-term abrasion can reduce the service life of gate valve；The corresponding torque of the vibration force of another aspect big valve core, can make
Valve rod generates torsion effect, if this torque is too big, it might even be possible to directly big valve core be damaged.
Therefore, there is an urgent need to a kind of Novel Brake Valves, even if pressure can obtain before and after big valve core in velocity of medium larger occasion
To reasonably releasing, valve rod operational torque is small, and spool easily opens and closes；After pressure is reasonably released before and after big valve core
Cause the with small vibration of big valve core, the abrasion of the sealing surface of spool and seal valve seat is small, gate valve long service life.This is just needed in master
Before cutting off big valve core unlatching, bypass is opened, pressure before and after balance big valve core is then turned on main cutting big valve core later, that is, is easy out
It opens and closes, do not damage big valve core, also do not allow to be also easy to produce very big vibration.
Utility model content
In order to overcome the shortcomings of existing research, the utility model patent provides a kind of super-pressure gate valve, even if in medium
