Abstract
The utility model discloses a semi-balanced type clean water valve which is characterized in that the bottom part of one end of a cylinder body is provided with a mounting hole; a piston rod is arranged in the mounting hole of the cylinder body and provided with a piston; a cylinder cover is arranged on the piston rod; a balancing sleeve is fixed on the cylinder cover by a bolt through a flange, and the piston rod penetrates out of the middle part of the balancing sleeve; a surge drum is arranged in an inner hole of the balancing sleeve and fixed on the piston rod through the mounting hole; one end of the valve body is fixed on the piston rod, and the other end thereof is welded on a valve clack; the valve clack and a tapered surface of a valve seat form a sealed surface; and a valve seat is clamped between an upper valve body and a lower valve body. The semi-balanced type clean water valve is opened instantaneously with lower lifting force, has low maintenance cost, and convenient assembly and disassembly of the piston rod.
Description
Technical field:
The utility model relates to the purge valve on a kind of slurry transfer pump, particularly slurry transfer pump.
Background technique:
Purge valve is to be used for mine slurry transfer pump---a kind of valve on the water isolation pump.Existing purge valve is mainly formed by driving oil hydraulic cylinder and purge valve body.Wherein driving oil hydraulic cylinder mainly is made up of piston, piston rod, cylinder body and cylinder cap; The purge valve body mainly is made up of valve body, flap, valve seat.Piston rod in the driving oil hydraulic cylinder directly drives the flap motion in the purge valve body, thus the opening and closing of control valve.Its major defect is: 1, during valve opening, only just opening in instantaneous blink, needing very big lifting force, and after opening process in, owing to the balance of flap upper and lower cavity slurry pressure, required lifting force significantly descends.But guarantee that valve normally opens, required lifting force designs when driving oil hydraulic cylinder and relevant hydraulic station thereof and must just open by valve, and this has just caused waste very big on the material and the energy; 2, piston rod is an easily damaged parts, and its cost is higher, the dismounting difficulty, and this has just increased the maintenance cost and the difficulty of equipment.
Summary of the invention:
The purpose of this utility model is to provide a kind of half balance formula purge valve, and this purge valve is less at the instantaneous required lifting force of unlatching, and maintenance cost is low, the piston rod easy accessibility.
The technical solution of the utility model is: half balance formula purge valve comprises driving oil hydraulic cylinder, Equilibrator and purge valve body.Wherein drive oil hydraulic cylinder and comprise cylinder body, piston, piston rod and cylinder cap; Equilibrator comprises surge drum, seal ring and balance set; The purge valve body comprises upper valve body, flap, valve rod, valve seat and following valve body.
Cylinder body is a hollow circular cylinder, and the bottom of one end is processed with mounting hole, and the other end has bead.Piston rod is installed in the mounting hole of cylinder body, and piston is installed on the piston rod.One end of piston is resisted against on the shoulder of piston rod, and the other end is fastening by nut, and forms sealing pair with cylinder body.Cylinder cap is installed on the piston rod by the hole at its middle part, and its end is resisted against on the cylinder body, and the other end is placed on the upper valve body, and the two ends of upper valve body are processed with bead.Cylinder body and upper valve body utilize stud to link together by their bead, and cylinder cap is sandwiched in therebetween.Balance set is the hollow circular cylinder that has bead, and is bolted on the cylinder cap by the bead utilization, and piston rod passes from the center.Surge drum is a hollow circular cylinder, is installed in the endoporus of balance set, and its outer surface can slide along the internal surface of balance set, between surge drum and the balance set seal ring is arranged.Surge drum also is fixed on the piston rod by its mounting hole.Valve rod one end is fixed on the piston rod by screw thread, and the other end is welded on the flap.The outer surface of flap is a conical surface, and the cone-shaped inner surface that is complementary with flap is arranged on the valve seat.Flap is installed in the endoporus of valve seat, and the conical surface of flap and valve seat forms sealing surface.Valve seat is sandwiched between upper valve body and the following valve body, and upper valve body, valve seat and following valve body utilize stud connecting to be one.
The beneficial effects of the utility model:
The utility model has reduced valve by the design balance device and has just opened instantaneous required lifting force, has saved material and has reduced energy consumption; Surge drum low with cost, easy accessibility replaces piston rod as easily damaged parts, has reduced the maintenance cost and the maintenance difficulties of valve
