Embodiment
Referring to Fig. 1 and in conjunction with Fig. 2, a kind of automatic negative-pressure hydathode for the preposition moisture trap of vacuum pump according to the utility model provides comprises a collecting container 1, is fixed with dividing plate 2 in the container 1, and dividing plate 2 is separated into epicoele 3 and cavity of resorption 4 with container 1.Epicoele 3 is provided with water intake 5 and negative pressure connecting tube 6.Offer connecting port 7 at dividing plate 2, the water that enters epicoele 3 can flow to cavity of resorption 4 through connecting port 7.Be placed with the first float 8 in the cavity of resorption 4.The top of the first float 8 is provided with sealing plug 9, and sealing plug 9 is over against the below of connecting port 7.When the first float 8 floated up to highest order, sealing plug 9 was just with connecting port 7 shutoff.The top of the first float 8 also is fixed with a push rod 10, and push rod 10 passes from connecting port 7 and enters in the epicoele 3.Be fixed with the sleeve pipe 11 that is overlapping push rod 10 in the epicoele 3.The lower end of sleeve pipe 11 is no more than connecting port 7, and the upper end of sleeve pipe 11 is through to outside the epicoele 3 from the top of epicoele 3.The top wall of the periphery wall of sleeve pipe 11 and epicoele 3 is tightly connected, in case the negative pressure in the epicoele 3 is revealed.The upper end of sleeve pipe 11 is connected with suction valve 12.The suction port 13 of suction valve 12 is communicated with atmosphere, and air outlet 14 is communicated with sleeve pipe 11.When the first float 8 floated up to highest order, push rod 10 backed down in sleeve pipe 11 is inserted into suction valve 12 and with the spool 15 in the suction valve, caused the suction port 13 of suction valve to be communicated with air outlet 14.The air outlet 14 of suction valve also is communicated to the cavity of resorption 4 of container by conduit 16.Conduit 16 is connected with dividing plate 2, so that conduit 16 is higher than the highest liquid level of cavity of resorption 4 at the interface position of cavity of resorption 4.The bottom of cavity of resorption 4 extends to form a secondary chamber 17 to side.The roof height in secondary chamber 17 is lower than the highest liquid level of cavity of resorption 4.The roof in secondary chamber 17 is provided with discharge opening 18.Top outside the secondary chamber is fixed with the sleeve 19 that is covering on the discharge opening 18.But be placed with the second float 20 of easy on and off activity in the sleeve 19, sleeve 19 also plays the effect that prevents the second float 20 lateral shifts.When the second float 20 dropped on sleeve 19 bottom, the second float 20 was just with discharge opening 18 shutoff.The lower sides of sleeve 19 is provided with drain opening 21.Be provided with the pore 22 that is communicated with atmosphere in the position that is higher than drain opening 21 of sleeve, so that the pressure in the sleeve 19 equals barometric pressure.
Below in conjunction with accompanying drawing 1～Fig. 3 working principle of the present utility model is described.
When just starting working, as depicted in figs. 1 and 2, the first float 8 is in the bottom of cavity of resorption 4, the epicoele 3 of container 1 is communicated with by connecting port 7 with cavity of resorption 4, epicoele 3 is by being communicated with the vacuum position of preposition moisture trap 23 negative pressure connecting tube 6, the inside of whole container 1 is in negative pressure state, so that the second float 20 is pressing discharge opening 18.Simultaneously, because the air outlet 14 of suction valve 12 is communicated with cavity of resorption 4 by conduit 16, so the air outlet 14 of suction valve 12 also is in negative pressure state, and spool 15 is pressing air outlet 14.The water of separating from preposition moisture trap 23 flows into epicoele 3 through water intake 5, is pooled to cavity of resorption 4 from connecting port 7 again.Along with the water levels in the cavity of resorption 4 constantly rise, the first float 8 rises to the extreme higher position, as shown in Figure 3, so the sealing plug 9 at the first float top with connecting port 7 shutoff, epicoele 3 and cavity of resorption 4 are isolated fully.Simultaneously, push rod 10 backs down spool 15, so suction port 13, air outlet 14 and the conduit 16 of atmosphere process suction valve 12 enter into cavity of resorption 4.After pressure in the cavity of resorption 4 became barometric pressure, as shown in Figure 3, the water level in the secondary chamber 17 was risen, and the second float 20 upwards floats, so the water in the cavity of resorption 4 outwards discharges through secondary chamber 17, discharge opening 18 and drain opening 21.In the starting stage of draining, although the buoyancy that the first float 8 is subject to reduces gradually, because cavity of resorption 4 has become barometric pressure, and epicoele 3 still keeps negative pressure, and therefore the first float 8 can't fall down at once.Continuous decrease along with cavity of resorption 4 water levels, the draught head of epicoele 3 and cavity of resorption 4, add the buoyancy that the first float 8 is subject to, no longer can support the weight (ignoring for the time being the pressure that the weight of the water in the epicoele 3 causes the first float 8) of the first float 8, so the first float 8 falls down automatically, return to Fig. 1 state, epicoele 3 and cavity of resorption 4 recover to be communicated with, the spool 15 of suction valve 12 falls and resets, and air outlet 14 is closed, and cavity of resorption 4 rebulids negative pressure state, so, the second float 20 is pressed on the discharge opening 18 under the suction function in deadweight and secondary chamber 17 again, enters next draining circulation.
Under Fig. 3 of above-mentioned working procedure state, the water that flows into epicoele 3 from water intake 5 can temporarily accumulate in the epicoele 3, even can have one's bosom filled with.These water that accumulate in the epicoele 3 can produce pressure to the first float 8, therefore, should consider the impact of this factor when design the first float 8 suffered buoyancy size, to guarantee that the first float 8 can not fall down too early after the beginning draining.
As preferred forms, as shown in Figure 1, the lower end of the sleeve pipe 11 of the present embodiment has the sealing surface 24 that cooperates with the sealing plug 9 at the first float top, when the first float 8 floats up to highest order, that is when state shown in Figure 3, sealing plug 9 is just pressing sealing surface 24, thus with the lower end shutoff of sleeve pipe 11.Like this, with regard to need not to consider the airtight problem between push rod 10 and the sleeve pipe 11, make the processing of push rod 10 and sleeve pipe 11 be more prone to.
Referring to Fig. 1, the present embodiment also is connected with blowdown valve 25 in the bottom of cavity of resorption 4, to maintain easily.Although the blowdown valve 25 among the figure is drawn in the position that is connected with secondary chamber 17, form because itself extend from the bottom of cavity of resorption 4 in secondary chamber 17, so blowdown valve 25 is connected with cavity of resorption 4 in itself.
As further improvement, referring to Fig. 1, first float 8 of the present embodiment is the hollow thin-wall structure, and its top wall offers fills mouth 26, fills mouth 26 and is stamped removable sealing cover 27.Sealing cover 27 be one with fill mouthful 26 plug screws that are threaded.So, can be by opening sealing cover 27, to the mode of the 8 interior water fillings of the first float or increase mass, the weight of fine adjustment the first float 8.In like manner, the second float 20 is also made the hollow thin-wall structure, also offers at its wall and fills mouth, and as float counterweight inlet, filling lid has removable sealing cover 28.Sealing cover 28 is plug screws.
