Description
Technical field
The invention belongs to pump works field of engineering technology, is specifically a kind of energy saving flap valve.
Background technology
Flap valve is cutout mode widely used in pumping plant, has the advantages that management is convenient, makes simple, traditional flap valve
Design starts upwards, and by the open-top flap valve of the impulse force of current, current are flowed out from the lower section of flap valve, and flap valve is in operation always
The flowing of current is hindered, produces larger hydraulic loss, by taking 100ZLB axial-flow pumps as an example, cast iron flap valve quality is up to 450kg, machine
Flap valve to be continued to jack up by pumping for water pump impulse force always during group operation, flap valve is pressed on head consumes much electricity for a long time,
Water pump efficiency is reduced, although the big resistance of flap valve opening angle can diminish, flap valve opening angle is bigger, and when closing impacts
Power is bigger, be easy to cause flap valve, caulking gum damage, mitigates flap valve weight if energy consumption is reduced and will result in flap valve closing
The problem of rear stability is poor, uses particularly in the Qiantang River and there is very big risk.
The content of the invention
In order to solve the above technical problems existing in the prior art, the present invention provides a kind of energy saving flap valve, by flap valve
Main body, connector, door shape tune weight plate, bar shape trench hole, stent, strut, bearing, hinge shaft, rubber slab, limited block composition, it is described
Flap valve main body by the weight plate fixed setting of connector and door shape tune together with, bar shape trench hole is opened in door shape tune weight plate
On, stent is fixed on outlet pipe together with strut fixed setting；The bearing is fixed at one with hinge shaft
Rise, and be fixed on outlet pipe, rubber slab is fixed in flap valve main body；The door shape tune weight plate can be around hinge shaft
Rotate and slide；When the flap valve main body opening angle is maximum, using strut position as fulcrum, the power of energy saving flap valve side generation
Square is more than the torque that door shape tune weight plate side produces.
A kind of energy saving flap valve disclosed by the invention, water impact flap valve main body during unit operation, flap valve body rotation, on
Lift, open, at the same door shape tune weight plate move flap valve main body to back lower place slide strips after move, flap valve main body opening angle is big, to current
Pressure very little, reduce energy consumption, when unit is out of service, flap valve main body to rotate, move down, pulls door shape tune weight plate reach, bat
Door main body slowly resets, and impact force is small, and flap valve, caulking gum are hardly damaged, and it is good that flap valve closes rear stability.
Brief description of the drawings
Fig. 1 is a kind of energy saving flap valve schematic diagram；
Fig. 2 is the flap valve schematic top plan view；
Fig. 3 is the flap valve schematic side view；
Fig. 4 is the flap valve working status schematic side view.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figs 1-4, a kind of energy saving flap valve of the invention, by flap valve main body 1, connector 2, door shape tune weight plate 3, bar
Shape slot 4, stent 5, strut 6, bearing 7, hinge shaft 8, rubber slab 9, limited block 10 form, and the flap valve main body 1 passes through connection
Together with part 2 is fixedly installed with door shape tune weight plate 3, bar shape trench hole 4 is opened on door shape tune weight plate 3, stent 5 and strut 6
Fixed setting together, and is fixed on outlet pipe, together with bearing 7 is fixedly installed with hinge shaft 8, and is fixed at out
On water pipe, rubber slab 9 is fixed in flap valve main body 1, and door shape tune weight plate 3 can be rotated and slided around hinge shaft 8.
A kind of energy saving flap valve of the present invention is in use, unit operation, water impact flap valve main body, flap valve body rotation, on
Lift, open, while door shape tune weight plate drives flap valve main body to be slided to the back lower place, hinge shaft withstands on bar-shaped trough under Gravitative Loads
Hole front end, flap valve main body opening angle is maximum, minimum to water flow pressure, greatly reduces energy consumption；When unit is out of service, because
The torque that energy saving flap valve side produces is more than the torque that door shape tune weight plate side produces, the flap valve main body under flap valve Gravitative Loads
Rotate, move down, be subject to the upward support force effect of strut, flap valve main body pulls door shape tune weight plate to move forwards, and hinge shaft is withstood on
Bar shape trench hole rear end, flap valve main body are slowly rotated, resetted, and whole flap valve closing process impact force is smaller, and flap valve, caulking gum are not
Fragile, after flap valve is closed, flap valve and door shape tune weight plate total weight are all pressed onto on water outlet, and stability is good, avoids existing
There is technology only to consider energy saving and reduce flap valve weight, cause flap valve to reduce water outlet pressure, reduce the stabilization after flap valve is closed
Sex chromosome mosaicism.
