Technical field
The utility model relates to a kind of ball valve, and particularly a kind of novel lengthened bar ball valve lengthens valve gap design, the design of valve pocket pressure releasing, and upstream and downstream pressure all can be by discharge internal pressure, protection equipment.
Background technique
Extension bar ball valve can directly be embedded in underground, need not build high large-scale valve well, only small-sized shallow well need be set on the ground, greatly saves operating expenses and engineering time.Can, according to the construction of pipeline and designing requirement, adjust the length of valve body and the height of valve rod.Existing product is only provided with an outlet valve at the bottom of valve, and no matter valve is in opening or closing position, and upstream and downstream pressure does not all discharge internal pressure completely, is the damage sharply raising and cause that is stressed of protection equipment, causes economic loss to user.
Model utility content
For the deficiency of existing product design, the utility model provides a kind of novel lengthened bar ball valve, comprises connecting body, outlet valve, plug, fuel feeding valve, Gland, support plate, spheroid, composite bearing, valve rod, positive stop key, resilient key, stationary axle pressing plate, main valve body, anti static device, stationary axle, seating spring, trim ring, valve seat.
The utility model solves the technological scheme that its technical problem adopts: outlet valve has two, and one is arranged on valve rod, and another is arranged on valve body side, and two outlet valves connect by outlet pipe, and by support, outlet valve and outlet pipe is interfixed; Spheroid bottom is provided with groove, at the bottom of ball, groove is square structure, in groove, be provided with composite bearing at the bottom of ball, stationary axle one end is connected to composite bearing at the bottom of the ball in groove, the stationary axle the other end is connected and fixed shaft pressuring plate, stationary axle pressing plate is fixed on main valve body bottom, and stationary axle and stationary axle pressing plate form " T " word structure; Spheroid top is provided with " one " word groove, " one " word groove and the vertical corresponding setting of square groove at the bottom of ball, valve rod bottom is designed to the protruding key of " one " word, valve rod bottom embeds groove, the protruding key of " one " word coincide with " one " word groove, valve rod bottom is provided with boss structure, and boss structure covers " one " word groove.
The beneficial effects of the utility model are: fluid resistance is little, easy to operate, open and close rapidly, need only half-twist from standard-sized sheet to complete shut-down, are convenient to remote control, very safe ready.
Brief description of the drawings
