The utility model relates to an oil field machinery technical field, in particular to ware is drawn to big pump valve. Should draw the ware including drawing the ware main part, the ware claw is drawn through two fixation nut installations to the one end of drawing the ware main part, draw through spring set screw coupling spring between the ware claw for two, it carries out concertina movement through the spring and blocks big pump valve to draw the ware claw for two, the other end of drawing the ware main part draws the horse through the ultra-thin hydraulic pressure of lock nut fixed mounting, the hydraulic pressure station draws the horse to provide hydraulic power the source to ultra-thin, ultra-thin hydraulic pressure draws the horse to promote lock nut through hydraulic power and draws big pump valve. The utility model provides a ware is drawn to big pump valve utilizes ultra-thin hydraulic pressure to draw rising of horse can draw out with the valve that damages under rising the circumstances that need not dismantle big pump bottom end cover, reduces and dismantles the link, has saved maintenance duration for the work efficiency who overhauls can improve.
