Compared to the prior art the utility model has following beneficial effect.
One, due to being designed to that the utility model adopts: upper butterfly valve centre bore and ball center are offset to respectively housing axis the same side; By spring, the jacking block of fixed mount is connected with the spiral shell elasticity that connects of valve lower end, valve can be up and down at valve inner.When liquid enters after filter screen from the entrance of upper end housing, because the fluid pressure that upper butterfly valve produces for a long-armed side is greater than the pressure that galianconism one side produces, above butterfly valve starts to clockwise rotate around mandrel, go up butterfly valve and drive pull bar simultaneously, pull bar drives ball to start to move downward along valve body upper pipes inwall, now the liquid pressure of filter screen inside acts on valve, outside liquid pressure acts on the lower end of barrier film, in the time that the pressure of filter screen inside approaches external pressure, active force and the spring pressure sum of external pressure to barrier film is greater than the active force of filter screen internal liquid pressure to valve, valve is in closure state, now go up butterfly valve and turn to gradually vertical opening, ball also moves to closed condition simultaneously, at this moment water (flow) direction is normal duty,
Along with liquid continuous inflow filter screen, liquid effects ball starts to rotate along straight tube, the moving pull bar of spherical zone simultaneously, pull bar drives upper butterfly valve to start counterclockwise motion, in the time that filter screen internal pressure is greater than external pressure certain value, internal pressure is greater than external pressure to barrier film and acting force of the spring sum to the active force of valve, valve is in opening, when valve is opened, ball moves to opening, upper butterfly valve also turns to the closed condition of level simultaneously, the inside and outside formation reverse differential pressure of filter screen, liquid carries out backwash to filter screen from outside to inside and discharges through blow-off pipe, water (flow) direction is backwash state.Backwash completes, and filter screen internal pressure and external pressure reach unanimity, and the power that liquid pressure acts on valve is less than the active force sum that acts on barrier film and spring, and valve is again in closure state, and the utility model returns to normal duty;
The utility model is not only simple in structure, and processing ease, can realize easily the work of automatic backwash, is also difficult for breaking down simultaneously, even if break down, keeps in repair also easier.
Two, the utility model adopts the design of two barrier films, and barrier film and lower diaphragm plate are set below valve, and the design of this pair of barrier film has improved withstand voltage greatly, and backwash effect is good simultaneously.
Three, the jacking block of the utility model fixed mount is movable, and be provided with the adjusting bolt contacting with jacking block through fixed mount bottom thread hole in fixed mount lower end, like this can be by the height that is screwed into, back-outs to regulate jacking block of adjusting bolt, and then carry out the active force of regulating spring docking spiral shell, this design make the utility model use convenient flexibly.
