Description
Technical field
Semi-automatic counter-flushing filter, belongs to filter technology field.
Background technology
Existing semi-automatic counter-flushing filter, a kind of is to utilize the backwash that manually realizes filter screen at outside switching butterfly valve; Another kind is the backwash of manually opening blowoff valve water pipe and realize filter screen, its structure comprises: shell, tubular filter screen, valve plate and blowoff valve, be provided with in the enclosure spring and water blocking, one end of spring is fixed on the spreader of shell, the other end and valve plate are fixed, and water blocking is connected with valve plate by stay cord, and valve plate central shaft is fixed on tubular filter screen, one end at tubular filter screen is provided with bottom, and the water pipe of blowoff valve is located on bottom.The former maintenance cost is higher.The latter's structure relative complex, need manually open, close blowoff valve water pipe, and it is convenient not to operate.
Utility model content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved is to provide a kind of semi-automatic counter-flushing filter simple in structure, easy to use.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: semi-automatic counter-flushing filter, comprise end housing, lower end housing, shell, butterfly valve, pull bar, ball valve, centring ring, filter screen, the filter end, blow-off pipe and delay-self-closing flush valve, described centring ring, filter screen and the filter end, are all arranged on enclosure, and centring ring is connected in the upper end of vertical filter screen, the filter end, is connected in the lower end of vertical filter screen, outer casing inner wall above centring ring is provided with the groove for blocking interior jump ring, be fixed with straight tube in bottom, the filter end, the lower end of described straight tube is embedded in the upper end of blow-off pipe, the lower end of described blow-off pipe is connected with shell through after shell, described delay-self-closing flush valve is connected with the lower end of blow-off pipe, have the groove of sealing ring in embedding in described centring ring outside, have the groove that embeds lower seal in described straight tube outside,
The middle and upper part of described filter screen inside is fixed with horizontal mandrel and spacer pin, middle and lower part are provided with ball valve, one end of described butterfly valve and pull bar is hinged, described ball valve is connected with the other end of pull bar, the centre bore matched in clearance of described mandrel and described butterfly valve, described spacer pin carries out spacing to the butterfly valve of level, the inwall matched in clearance of described ball valve and described straight tube, and the centre bore of butterfly valve and the center of ball valve are all offset the same side at filter screen axis;
The hoop tube adaptor that is provided with socket shell and upper end housing in the junction of described shell upper end and upper end housing, described lower end housing is connected in the lower end of shell.
Center line at the bottom of described upper end housing, lower end housing, shell, centring ring, filter screen, filter is on same straight line.
Described filter screen is the cylinder of MULTILAYER COMPOSITE.
The position that mandrel is set at described filter screen is socketed with welding ring.
Compared to the prior art the utility model has following beneficial effect.
One, due to being designed to that the utility model adopts: butterfly valve centre bore and ball valve center are offset to respectively to housing axis one side; In one end through shell of blow-off pipe, blowdown end connects delay-self-closing flush valve.Under normal operating conditions, delay-self-closing flush valve is closed condition, liquid enters after filter screen from the entrance of upper end housing, because the fluid pressure that butterfly valve produces for a long-armed side is greater than the pressure that galianconism one side produces, so butterfly valve starts to clockwise rotate around mandrel, butterfly valve drives pull bar, pull bar to drive ball valve to start to move upward along straight tube simultaneously, and butterfly valve turns to vertical opening afterwards.Along with liquid continuous inflow filter screen, when pressure differential inside and outside filter screen is larger, operating personnel's opening time-delaying self-closing flush valve, liquid effects ball valve starts to move downward along straight tube, ball valve drives pull bar, pull bar to drive butterfly valve to start counterclockwise motion simultaneously, butterfly valve turns to the closed condition of level afterwards, interior low outer high reverse differential pressure is formed at filter screen bottom afterwards, liquid carries out backwash to filter screen from outside to inside and discharges after blow-off pipe, delay-self-closing flush valve, and water (flow) direction is backwash state.After backwash completes, delay-self-closing flush valve is closed automatically, and the utility model returns to normal duty;
The utility model is not only simple in structure, and processing ease, after operating personnel's open time delay self-closing flush valve, need not wait for again, after backwash completes, delay-self-closing flush valve can be closed automatically, thereby realizes easily the work of backwash, and the utility model is also difficult for breaking down simultaneously, even if break down, keep in repair also easier.
Two, by the position socket welding ring of mandrel is set at filter screen, the two ends of mandrel and welding ring are welded, can be more firm mandrel and filter screen are fixed.
Three, be set to by delay-self-closing flush valve that working flow is adjustable, adjustable delay-self-closing flush valve of working time, can regulate more flexibly backwash work.
