Description
Technical field
A kind of anti-positive pressure ventilation valve and negative-pressure cup drainage system, belong to valve technology field.
Background technology
A kind of negative-pressure cup utilizing principle of negative pressure to draw water, first has to being full of water in negative-pressure cup before equipment work, works as water level
When reaching to manage interior suction hose top, illustrating that negative-pressure cup fills with, as filled, unnecessary water will flow into ground by suction hose in tank again
In sink, being full of after water and switch on the pump, the water in tank is constantly pumped, and in tank, water level constantly declines, in negative-pressure cup pressure by
Gradually form negative pressure, and vacuum degree constantly increases, under atmospheric pressure, the hydraulic pressure in pond is entered the outer suction hose of tank, source, water source
Constantly it is pumped in negative-pressure cup, is discharged by water pump the most continually simultaneously.
But, when water filling in tank first, it is original air entirely in tank, when bath in tank, original air in tank
It is compressed in top in tank, it addition, when water pump is opened, be also air originally in suction hose in tank, the once sky in suction hose
Gas is sucked in tank, and in tank, air have impact on too much and produces enough negative pressure, and the water in sink is likely to just take out to come up, or
Quickly become malleation in person's negative-pressure cup cannot absorb water, and owing to water pump and negative-pressure cup links can not fully seal, such as
Between centers has gap certainly, and air is all-pervasive, and in tank, vacuum degree will reduce, the weight of water in vacuum degree can not bear suction pipe
Time, the water in suction hose just falls in pond, and suction hose becomes again air, and when again starting pump, the air in suction hose is again
Being drawn in negative-pressure cup, if repeatedly start-stop water pump, the air in negative-pressure cup gets more and more, and vacuum degree is more and more lower, water in tank
Position is the most fewer and feweri, and last negative pressure becomes malleation, and water pump leaves and also do not takes out water, thus have impact on service life, and impact is just
Often work.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, work

Detailed description of the invention
1 ~ 3 further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings.
In conjunction with Fig. 1 ~ 3, the one anti-positive pressure ventilation valve that the present embodiment proposes, including upper flange 1, upper sealing gasket 2, guide way
3, spool 4, lower seal pad 5, spring 6, lower flange 7 and valve block 17, guide way 3 is the structure of straight-run of pipe two ends welded flange,
Spool 4 is installed in straight length, spool 4 be two ends be cone mid portion be the ducted body of cylindrical section, and the circle of spool 4
Shell of column be respectively fixed at two ends with an astragal ring-shaped valve jaggy 17, interior less than guide way 3 straight length of valve block 17 external diameter
Footpath, spool 4 can slide up and down in the straight length of guide way 3, and upper sealing gasket 2 and lower seal pad 5 are annular seal packing ring, upper method
One end in the centre bore of blue 1 is machined with internal coiling, the other end have groove that the external diameter size with upper sealing gasket 2 matches and on
The internal diameter of sealing gasket 2 is identical with the internal diameter of upper flange 1, and upper sealing gasket 2 is fixed in the groove of upper flange 1, the center of lower flange 7
One end in hole is machined with female thread, and the other end has groove that the external diameter size with lower seal pad 5 matches and lower seal pad 5
Internal diameter is identical with the internal diameter of lower flange 7, and lower seal pad 5 is fixed in the groove of lower flange 7, fixing in the centre bore of lower flange 7
Having spring 6, the flange at the two ends of guide way 3 is connected with upper flange 1 and lower flange 7 bolt seal respectively, and make upper flange 1 and under
The female end of flange 7 outwardly, owing to the elastic force of spring 6 promotes spool 4, makes spool 4 separate with lower seal pad 5, in negative-pressure cup
Being connected with outside atmosphere, when moisturizing in negative-pressure cup, in tank, air can be discharged in tank by valve block 17 opening.
When water pump is opened, and the water in negative-pressure cup is constantly discharged, owing to pumping drainage speed is more than anti-positive pressure ventilation valve 14
Intake velocity, negative pressure pressure inside the tank constantly declines, and spool 4, under the effect of negative pressure, overcomes the elastic force of spring 6 to move down, makes
The conical surface of the cone of spool 4 gradually contacts with lower seal pad 5 and seals, and makes extraneous air cannot be introduced into.
A kind of negative-pressure cup drainage system, including suction hose 11 in tap water pipe line 8, moisturizing electromagnetic valve 9, filter 10, tank,
Negative pressure tank body 12, tank outer suction hose 13, anti-positive pressure ventilation valve 14, exhaustor 15, pump water draining device 16, negative pressure tank body 12 top
If a water inlet docks with tap water pipe line 8, in order to realize automatically controlling, water inlet pipe is installed a moisturizing electromagnetic valve 9,
For preventing moisturizing electromagnetic valve 9 from blocking, filter 10 is installed between tap water pipe line 8 and moisturizing electromagnetic valve 9, negative pressure tank body 12
Having air vent on end socket, and connect exhaustor 15, exhaustor 15 is threadeded with anti-positive pressure ventilation valve 14, the outer suction hose 13 of tank
Being arranged on negative pressure tank body 12 outside, and be connected with external water source, in tank, suction hose 11 lower end suction hose 13 outer with tank is connected, in tank
Suction hose 11 upper end is arranged on the top of negative pressure tank body 12 and the upper open height position less than air vent, the lower end of negative pressure tank body 12
Pump water draining device 16 is set.
When pump water draining device 16 shuts down, moisturizing electromagnetic valve 9 automatically opens up, and tap water pipe line 8 starts to negative pressure
Moisturizing in tank body 12, the air in negative pressure tank body 12 is discharged by anti-positive pressure ventilation valve 14 simultaneously, when inhaling in water level and tank in tank
Water pipe 11 suitable for reading concordant after, moisturizing electromagnetic valve 9 cuts out, and stops moisturizing, outside unnecessary water can be flowed into by suction hose 11 in tank
Water source, portion, as long as moisturizing electromagnetic valve 9 cuts out, pump water draining device 16 is switched on, as long as pump water draining device 16 is closed, moisturizing electricity
Magnet valve 9 is switched on, tap water just moisturizing in tank, it is ensured that forever have water in tank, as long as having the water of abundance, pumping drainage in tank
Negative pressure, under atmospheric pressure, the cone conical surface of the spool 4 of anti-positive pressure ventilation valve 14 will be formed in tank when device 16 starts
Gradually sealing with lower seal pad 5, pump water draining device 16 continues draining, and the vacuum degree in negative pressure tank body 12 is the highest, and water is just by tank
Outer suction hose 13 pumps.
When anti-positive pressure ventilation valve 14 being arranged in tank below the upper actinal surface of suction hose 11, when moisturizing electromagnetic valve 9 is in tank
Moisturizing, in tank, air can be discharged from anti-positive pressure ventilation valve 14, when in tank, water exceedes the setting height(from bottom) of anti-positive pressure ventilation valve 14, water
Can hold up spool 4 through lower flange 7, spring 6, lower seal pad 5, spool 4 seals with upper sealing gasket 2, and anti-positive pressure ventilation valve 14 closes
Close, prevent water excessive.
