Embodiment 1
As shown in Figure 2,3, a kind of self-priming water pump negative-pressure vacuum water fetching device, comprise self-priming pump 103, suction pipe 106, filter 203 and air shut-off valve 206, grid 202 is housed as the coarse filtration net on the water intake of described suction pipe 106, described filter 203 turns on the above ground portion of suction pipe 106, for cleaning and the maintenance of convenient filter 203, filter 203 is detachably installed; The water intake of filter 203 is communicated with the water outlet of suction pipe 106, and the water outlet of suction pipe 106 is communicated with the water intake of self-priming pump 103; Filter screen 105 is housed in filter 203, filter 203 bottoms have the sewage draining exit be communicated with drain pipe 204 and are used for draining-off sewage, be connected to recoil scavenge pipe 207 on filter 203 for flushing filtering net 105, described air shut-off valve 206 is arranged on the air intlet at filter 203 tops.
The utility model can further describe into, described air shut-off valve 206 comprises valve body 300, piston rod 301 and valve gap 304, described valve gap 304 is arranged on the top of valve body 300, described piston rod 301 is arranged in valve body 300, piston 302 and Returnning spring 303 are housed on piston rod 301, the sealing plug 307 matched with filter 203 air intlets is equipped with in piston rod 301 bottoms, described piston 302 becomes control room and gas permeable vents two-part by valve body 300 interior separations, between piston 302 and valve body 300 inwalls, by sealing gasket, seals; The control mouth in described control room is connected with PRESSURE PIPE 306, has air hole 305 on described gas permeable vents; The air intlet that the press water that piston rod 301 provides in PRESSURE PIPE 306 is closed filter 203 tops by sealing plug 307 under driving, the valve gap 304 at air shut-off valve 206 tops is friction top, and valve gap 304 is installed and just can be forced to depress the air intlet that piston rod 301 is closed filter 203 tops conversely; After PRESSURE PIPE 306 internal pressures disappear, under the effect of Returnning spring 303, sealing plug 307 is opened, and filter 203 is communicated with atmosphere by air hole 305.
In order to be convenient to observe the situation of filter 203 inside, have viewing window 205 on described filter 203, by transparent viewing window 205, observe blockage and the current situation of filter screen, be convenient to clean on applicable opportunity filter screen 105, also can observe the degree of vacuum of filter 203 inside simultaneously.
In the present embodiment, in order to realize automatically controlling, the action that makes air shut-off valve 206 automatically follow self-priming pump 103 opens and closes, and the control mouth of described air shut-off valve 206 is communicated with the water outlet of self-priming pump 103 by PRESSURE PIPE 306; After self-priming pump 103 starts, vane rotary, water in the pump housing is that outlet pressure rises, pressure makes air shut-off valve 206 close the air intlet at filter 203 tops through PRESSURE PIPE 306, and along with the effect of self-suction pump impeller, the gas in inlet pipeline is got rid of the pump housing gradually, water in pond is drunk up, now can observe water level rising situation by viewing window 205, after water is full of filter 203, self-priming pump 103 enters and continues to send water state.If continue not inhale water, must on pipeline, the gas leakage point be arranged.Valve gap 304 upsets are installed and can be carried out hand-operated forced air intlet of closing filter 203 tops, and this is very easily when speed governing and fault diagnosis; When self-priming pump 103 termination of pumping, PRESSURE PIPE 306 pressure disappear, sealing plug 307 is opened under the effect of Returnning spring 303, filter 203 is communicated with atmosphere by air hole 305, now the water in suction pipe 106 falls back in pond under Action of Gravity Field, because filter 203 connects with atmosphere, make the water in self-priming pump 103 be unlikely to because siphonage is cleared, otherwise next startup can't complete exhaust.
In the present embodiment, in order to improve the suction capactity of suction pipe 106, horn mouth 201 is housed on the water intake of described suction pipe 106.
By, to the transformation of three inlet of self-sucking pump intake lines, after practicing a period of time, effect makes us being satisfied with very much, through cleaning and filtering several times, foreign material in pond is got rid of, and no longer needs pond clearly to keep in repair.Because setting up horn mouth, suction pipe forms tapered absorption pipe structure, has strengthened the inlet capacity of pump, and the 3.5Mpa of degree of vacuum before by transformation brought up to 5Mpa, and the same water flow of sending, and current of electric obviously descends.
