Description
Technical field
The present invention relates to a kind of equipment of low-lift pump device, relate in particular to the damming and reduce the device of water outlet water flow dynamic energy loss of open type pump of vertical installation, belong to the hydraulic engineering technical field.
Background technique
That the open type pump-unit of vertical installation has is simple in structure, construction investment province and installation, the advantage such as easy to maintenance, suitable especially various lots of middle-size and small-size low lift pumping plant and the two-way pumping plant that draws water of being applied to.But because the outlet passage of this pattern pump-unit adopts the open type water outlet, the water surface seethes acutely, has caused larger water flow dynamic energy loss, has limited the raising of pump assembly efficiency.On the other hand, the speed reversal of motor is no more than safety range when water pump is shut down, and pump-unit need configure the blocking devices that dam such as flap valve or stop gate, and not only device structure is complicated, maintaining is inconvenient, and investment is many.
Summary of the invention
Purpose of the present invention is exactly for above-mentioned the deficiencies in the prior art, a kind of movable cavity water guide control valve unit with vertical open pump-unit of diversion function is provided, in the open type pump-unit advantage that keeps vertical installation, can overcome the lower defective of pump assembly efficiency, this device also can be used as the blocking device that dams simultaneously.
the object of the present invention is achieved like this, the movable cavity water guide control valve unit of vertical open pump-unit, comprise the fixedly water guide cone that is mounted on the exit of pump top, the exit of pump oviduct, the outlet passage upper cover plate, it is characterized in that, be provided with the movable cavity water guide valve that is inversed taper platform shape between described exit of pump oviduct and outlet passage upper cover plate, described Pump Axle periphery is provided with sleeve pipe, the sleeve pipe setting be fixed on the outlet passage upper cover plate below, sleeve pipe is with fixedly the water guide cone concentric is corresponding, described movable cavity water guide valve is the closed cavity structure, by inner tube, outer tube, curved tube wall and top cover consist of, inner tube, the outer tube top connects top cover, curved tube wall upper end is plane and is connected with the bottom of outer tube, inner tube lower end outer wall is connected with curved tube wall, diameter of inner pipe is greater than described casing diameter and fixing water guide cone diameter, movable cavity water guide valve is set on described sleeve pipe by inner tube, the mouth of pipe of described exit of pump oviduct is provided with O type rubber seal.
The unit weight of described movable cavity water guide valve is slightly larger than water.
Clash into for preventing that upper cover plate outer rim and movable water guide valve from producing, the outer rim above top cover is provided with elastic ring, and the relevant position is provided with flange collar below the outlet passage upper cover plate simultaneously.
Described sleeve pipe equates with the fixing upper diameter of water guide cone.
The movable cavity water guide valve that unit weight is slightly larger than water is set between exit of pump oviduct and outlet passage upper cover plate, when water pump normally moves, this activity cavity water guide valve upwards floats under the hydrodynamic pressure effect of exit of pump, the determining positions of floating is in the water level of water outlet pool, being close to the curved tube wall of this activity cavity water guide valve from the current of water pump outflow flows, eliminated the phenomenon that the original device oviduct outlet water surface seethes, this activity cavity water guide valve is brought into play guide functions at this moment.When movable cavity water guide valve upwards floats, owing to being provided with elastic ring, avoid hitting with the hard hit of outlet passage upper cover plate the protection device security under the hydrodynamic pressure effect of exit of pump.When water pump assembly is shut down; this activity cavity water guide valve is because the acting in conjunction of water outlet pool water pressure and deadweight thereof is fallen; nestable in the fixing outside of water guide cone, and compress the rubber seal that is arranged on the oviduct mouth of pipe, this activity cavity water guide valve is brought into play the effect of the locking of damming at this moment.
The present invention is rational in infrastructure simple; novel; with ingenious cooperation of open type pump-unit of vertical installation; be used for the water conservancy diversion of exit of pump current, significantly reduced loss of head; the locking of damming when also can be used for simultaneously the water pump assembly shutdown; reduce the accessory of pumping plant, saved construction investment and maintenance cost.
