Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described.
Different according to caliber diameter, the utility model can be divided into small-sized flap valve valve (diameter is 100 ~ 800mm) and big-and-middle-sized flap valve valve (diameter is greater than 800mm). As shown in Figure 1 and Figure 2, small-sized self-sealing energy-saving flap valve valve comprises valve seat 5 and wholecircle valve plate 1, valve seat 5 is fixed on pipeline 12 or channel exit end by flange 4 and anchor frame, the side of wholecircle valve plate 1 is hinged on the side, end of valve seat 5 by inner position hinge 2, inner position hinge 2 is valve plate angular stop means for valve plate when opening, prevent valve plate from exceeding angle, there is the effect of bearing simultaneously; Another side of wholecircle valve plate 1 is provided with the magnetic device 3 of relative effect with the correspondence position of valve seat 5. As shown in Figure 2 and Figure 3, end face inner circumferential ring portion at valve seat 5 is fixed with the first wedge shaped seal 6 by fastening piece, the corresponding inner side ring portion of wholecircle valve plate 1 is fixed with the 2nd wedge shaped seal 7 by fastening piece, when wholecircle valve plate 1 closes, the first wedge shaped seal 6 and the 2nd wedge shaped seal 7 realize sealing by contact of incline plane, have and seal effect preferably.
As shown in Figure 4, Figure 5, big-and-middle-sized self-sealing energy-saving flap valve valve comprises valve seat 5 and two blocks, left and right semicircle valve plate 9, valve seat 5 is fixed on pipeline 12 or channel exit end by flange 4 and anchor frame, the arc section side of semicircle valve plate 9 is hinged on the side, end of valve seat 5 by inner position hinge 2, the diameter portion side of the two blocks of semicircle valve plates 9 in left and right is oppositely arranged and forms whole circle, and diameter portion upper and lower is provided with magnetic device 3. In the central authorities of the open end-face of valve seat 5, vertically it is provided with central sill 8, corresponding with the diameter portion of semicircle valve plate 9 outside central sill 8, it is provided with wedge shaped seal inside central sill 8, valve seat 5 and semicircle valve plate 9, during valve closes, realizes sealing; The inner side of central sill 8 is indent arc, is scratch resistant slag sawtooth 10 in the middle part of arc, and arc top and the bottom are anti-extension nose girder 11, arrange inclined-plane between anti-extension nose girder 11 and scratch resistant slag sawtooth 10.
During real work, horizontal valve plate opening structure of the present utility model, it is possible to being opened by valve plate by less head, the angle of unlatching generally reaches 80 ~ 85 degree, is reducing the energy consumption simultaneously reducing pump of head. The impurity of dross easy in fluid is guided by the inclined-plane between anti-extension nose girder 11 and scratch resistant slag sawtooth 10, make it landing or taken out of by current, the disintegrating slag sawtooth of the longer dross of a part in the middle part of nose girder is ground disconnected, and along with current flow away removing, thus sealing place making valve part is not easy card slag. Valve plate is that side, left and right is opened, when opening angle is bigger, due to valve plate center of gravity and sea line is angled steeves above side, under gravity, valve plate is inwardly closed, before valve plate and valve body close, general is all itself and valve body are sealed by the pressure of water, but when water level is lower, there will be the insufficient pressure of water, cause valve plate and valve body seep water than sealing and leak. By the combination of wedge shaped seal and magnetic subassembly, not only solve common flap valve valve plate and valve body closing displacement amount big, the easy aging leakage water problem of ordinary seals, the effect also adsorbed by magnetic force, solve the problem that when water level is lower outside, valve can not agree with compacting and cause water leakage bigger than normal very well, improve system efficiency, reduce system energy consumption.
More than describing is to explanation of the present utility model, is not the restriction that practicality is novel, and when not running counter to the utility model spirit, the utility model can do any type of amendment.
