Abstract
The utility model provides a take sealing rib's spill discharge check valve is the bowl form, surrounds the wash port of diaphragm chamber's high pressure chest, including a plurality of valve blocks district, the peripheral sealing rib that forms of every valve block district lower surface. The utility model discloses a take sealing rib's spill discharge check valve makes the face seal into linear sealing through sealing rib, increases sealed degree, reduces sealed face and goes up deposit dirt, impurity, and the microorganism goes up the influence of growing and bringing the leakproofness at sealed face even, does when absorbing water the action at utmost in the low pressure chamber from the water storage chamber and prevents the water under high pressure against the current to low pressure chamber, improvement pump drainage efficiency.
Description
Technical field
The utility model belongs to reverse osmosis suction booster field, and specifically a kind of spill with sealed muscle discharges safety check.
Background technique
Existing reverse osmosis boosting pump structure, its structure is presented as that chamber of septum has low-pressure cavity, hyperbaric chamber and water storage cavity, and hyperbaric chamber is concavity sphere, is distributed with weep hole, discharge safety check and be positioned at hyperbaric chamber, and surround weep hole, low-pressure cavity is distributed with suction hole, and inhalation check valve covers suction hole, under the effect of the escapement of driven by motor, the water of water storage cavity sucks low-pressure cavity after suction hole, and setting-out, to hyperbaric chamber, is discharged by hyperbaric chamber.
As shown in Figure 1, when low-pressure cavity does water suction action from water storage cavity, discharge safety check can only cover weep hole ideally and seal it, and this sealing is face sealing, easily occurs revealing; After suction booster long-time running, discharge meeting dirt deposits, impurity on safety check, microorganism grows on the sealing surface of discharging safety check even, sealing surface is caused to be not closed completely, in low-pressure cavity water absorption course, comparatively early occur that high pressure water adverse current returns low-pressure cavity, affect pump drainage efficiency.
Model utility content
In order to solve the above-mentioned technical problem existed in prior art, the utility model provides a kind of spill with sealed muscle and discharges safety check, in bowl-shape, surrounds the weep hole of the hyperbaric chamber of chamber of septum, comprise multiple valve block district, each valve block district lower surface periphery forms sealed muscle.
Further, the height of described sealed muscle is 0.2-0.7mm.
Further, described hyperbaric chamber is provided with the radial groove of location, and this spill is discharged on safety check lower surface and arranged convex tendon, and this convex tendon is embedded into radial groove and is combined together, the position that this spill discharges the corresponding convex tendon of safety check upper surface is provided with muscle, thus valve block is divided into multiple valve block district.
The spill of band sealed muscle of the present utility model is discharged safety check and is made face sealing into linear sealing by sealed muscle, increase tightness, reduce dirt deposits, impurity on sealing surface, microorganism grows the impact brought sealing on sealing surface even, at utmost stop high pressure water adverse current to low-pressure cavity when low-pressure cavity does water suction action from water storage cavity, improve pump drainage efficiency.
Accompanying drawing explanation
Fig. 1 is that the spill of prior art discharges non-return using state schematic diagram;
Fig. 2 is the structural representation of chamber of septum;
Fig. 3 is that the spill of band sealed muscle of the present utility model discharges check valve structure schematic diagram;
Fig. 4 is that the spill of band sealed muscle of the present utility model discharges safety check bottom schematic view;
Fig. 5 is that the spill of band sealed muscle of the present utility model discharges safety check using state schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As in Figure 2-4, the spill of band sealed muscle of the present utility model discharges safety check, in bowl-shape, surround the weep hole 3 of the hyperbaric chamber 2 of chamber of septum 1, bottom it, sphere curved surface rate is identical with hyperbaric chamber 2, hyperbaric chamber 2 is provided with the radial groove 4 of location, this spill is discharged on safety check lower surface and is arranged convex tendon 5, this convex tendon 5 is embedded into radial groove 4 and is combined together, the position that this spill discharges the corresponding convex tendon 5 of safety check upper surface is provided with muscle 6, thus valve block being divided into multiple valve block district, each valve block district lower surface periphery forms sealed muscle 7.Preferably, the height of sealed muscle 7 is 0.2-0.7mm.
As shown in Figure 5, after spill discharge safety check is installed to hyperbaric chamber, due to the convex effect of sealed muscle, valve block district seals the weep hole 3 of hyperbaric chamber 2 closely.Even if adjacent valve section opening encapsulation also can not be affected.
Check experiment
In order to the sealing effect checking the spill arranging sealed muscle to discharge the discharge safety check of safety check and prior art, following experiment is set.
Test condition:
Dry state self-priming is tested: normal temperature 25 °, and pump head inside is anhydrous, water outlet access pressurized gas;
Air leakage: normal temperature 25 °, pump head inside is anhydrous, water outlet access 0.2Mpa pressurized gas, in the water that submerged by entery and delivery port 1 minute, measures number of bubbles.
Working state
Voltage: 24v water outlet pressure: 0.5Mpa; Shutoff water outlet;
Testing apparatus:
DC power supply, air leakage detector, suction lift testing apparatus, three industry control test platforms, measuring cup, Chronograph, noise instrument, turbidimeter, omnipotent pressure test machine, digital display thermostat water bath, Shore durometer.
Test result:
For the first time:
For the second time:
For the third time:
Visible, after changing the spill discharge safety check of band sealed muscle of the present utility model, the sealability of hyperbaric chamber improves greatly, and because moulding different batches product exists change in drain opening local, after using this spill to discharge safety check, the conformity of batch performance improves simultaneously greatly.
