Below in conjunction with embodiment and accompanying drawing the present invention is described in further detail.
Fig. 1, Fig. 2 are embodiments of the invention one.This diaphragm type negative pressure valve that is used for sewage transport mainly comprises the valve body 1, seal membrane 2, lifting gear and the cylinder body that are arranged on the negative-pressure pipeline, it is characterized in that:
Be stamped lower cylinder body 14 on the outer ring of middle pressure body 4, lower cylinder body 14 is formed whole cylinder body with upper cylinder body 12, and upper cylinder body 12 tops have a negative pressure hole 11; The middle centre circle of body 4 of pressing is outstanding in valve body, is pressed on the above-mentioned sealing surface below it, and the middle inner ring of body 4 of pressing is projecting inward to lower cylinder body, forms one and supports the ring platform of going up collapser 10 and following collapser 8 and suction iron 7, and this is embedded with permanent magnet 5 and damping pad 6 above ring platform;
The step 20 of lifting gear pull bar 3 upper ends is positioned at above-mentioned cavity, and with cavity the free gap is arranged, and formation flexibly connects, and the nut 24 of lifting gear pull bar 3 lower ends embeds in the seal membrane, and lifting gear pull bar 3 middle parts are with pressure spring 21.
Last collapser 10, following collapser 8 and inhale iron 7 and link together by screw.
Be fixedly connected with nut in the middle of the seal membrane, nut is connected with pull rod screw.
The present invention compares with the piston type negative pressure valve, and the main distinction is in the lifting device that the present invention adopts and promotes diaphragm 9, upward collapser 10 reaches collapser 8 down, replaces the piston and the Sealing of the piston type negative pressure valve of sewage transport; Adopt the return power of permanent magnet 5, replace the pressure spring of the piston type negative pressure valve of sewage transport as lifting device.Promote diaphragm 9 as lift elements, make epicoele 13 not have leakage fully, and zerofriction force.Have only the negative pressure when epicoele 13 to be enough to overcome permanent magnet gravitation, the seal membrane 2 of negative pressure valve could be opened, and lifts fast.In opening process, with the increase that promotes displacement, seal membrane 2 and the deformation resistance that promotes diaphragm 9 increase, and the gravitation of permanent magnet 5 is reducing fast, and are square proportional with distance.Thus, can reduce resistance total in the lifting process.Negative pressure valve closes in the closed procedure, and originally by the deformation force of 2 diaphragms, behind effective attraction zone of arrival permanent magnet 5, permanent magnet gravitation becomes main return pulling force, and is into the quadratic relationship increase.The introducing of above-mentioned permanent magnet 5 can make negative pressure valve realize opening fast and quick closedown.
A pre-buried nut 24 in the middle of the seal membrane 2, the helical thread portion of pull bar 3 is threaded onto wherein.
Press the top of body 4 in the centre, stud with permanent magnet 5 and damping pad 6.Relative with it, have one to inhale iron 7, inhale iron 7 and be connected and one with last collapser 10, following collapser 8 and lifting diaphragm 9.Suction iron 7 is pressed against on the damping pad 6 because of the suction of permanent magnet 5, and limited.
In the middle of the bottom of following collapser 8, a cavity 17 is arranged, its effect is equivalent to the slotted hole in the piston type negative pressure valve of sewage transport.Cavity 17 bottoms have hole 18, and the diameter in hole 18 is greater than the bar footpath of pull bar 3, and pull bar 3 passes therethrough.The top of pull bar 3 is the step 20 of a projection, and effect is equivalent to the pin among the embodiment one.Step 20 diameters are less than cavity 17.As described in embodiment one, by pull bar 3, step 20, pressure spring 21, cavity 17 and hole 18, constituted and can swing and telescopic connection, the present invention is referred to as to flexibly connect.The diameter in cavity 17 and hole 18 makes to flexibly connect and can realize swing respectively greater than step 20 and pull bar 3; The elongation that flexibly connects, the spring-back force of the pressured spring 21 that contracts; The shortening that flexibly connects, outer power applies.
To promote diaphragm 9 is the boundary, has upper cylinder body 12 and lower cylinder body 14 thereon, and forms epicoele 13 and cavity of resorption 15 respectively, does not communicate with each other.Epicoele 13 communicates with sourceof negative pressure by negative pressure hole 11, and cavity of resorption 15 communicates with atmosphere by normal pressure hole 16.Promote diaphragm 9, go up collapser 10, collapser 8 and inhale iron 7 and constitute lifting device of the present invention down, it is driving force with the negative pressure.5 pairs of permanent magnets are inhaled iron 7 a downward attraction force.
As shown in Figure 1, be in the structural representation of closed condition for the present invention.Negative pressure hole 11 all communicates with atmosphere with normal pressure hole 16 simultaneously, makes epicoele 13 and cavity of resorption 15 be under the same barometric pressure.Permanent magnet 5 attracts iron 7, drives thus to go up collapser 10, following collapser 8 and promote diaphragm 9 to be pressed against downwards on the damping pad 6, and limited.Descending 2 of collapser 8 and seal membranes, pressure spring 21 is housed, seal membrane 2 is pressed against on the protruding weir 22.In most cases, the dirt inlet 19 of valve body 1 is in barotropic state, and the dirt-discherging outlet 23 of opposite side is in negative pressure state, with protruding weir 22 is the boundary, half of seal membrane 2 born malleation, and second half bears negative pressure, causes seal membrane 2 distortion, the center portion produces deflection, and this deflection can pass to the pull bar 3 that connects firmly with it.As mentioned above, the diameter in cavity 17 and hole 18 is respectively greater than step 20 and pull bar 3, can compensate pull bar 3 deflections that the distortion because of seal membrane 2 causes, and this deflection can be delivered on the lifting device.In addition, in design, 5 pairs of permanent magnets are inhaled the attraction forces of iron 7, are greater than the working pressure of pressure spring 21, therefore, can guarantee that whole lifting device is pressed against on the damping pad 6 upper support faces.Following collapser 8 provides impacting force by pressure spring 21 to seal membrane 2, rather than directly power is passed on seal membrane 2 by following collapser Final 8 hard place.Certain space is all left with cavity 17 in the upper edge of step 20 and lower edge, when inhale iron 7 limited after, the return error of seal membrane 2 can be eliminated in this space, and the return of lifting device is not exerted an influence.
Fig. 2 is in the structural representation of opening state for the present invention.Negative pressure hole 11 is connected with sourceof negative pressure, and normal pressure hole 16 communicates with atmosphere, and there is pressure reduction in epicoele 13 with cavity of resorption 15, and lifting diaphragm 9 is moved up.As mentioned above, initial position, certain space is all left with cavity 17 in the upper edge of step 20 and lower edge, is in the neutral position of cavity 17 substantially.Drive and go up collapser 10, collapser 8 and when inhaling iron 7 and moving up down when promoting diaphragm 9, pull bar 3 is the same moving thereupon not, and promptly seal membrane 2 keeps and the sealing on 22 on protruding weir.Meanwhile, following collapser 8 increases with the spacing of seal membrane 2, and pressure spring 21 extends because of elasticity, simultaneously, following collapser 8 is produced Driving force upwards.Instantly move on on collapser 8 continues when contact with the lower end surface of step 20, seal membrane 2 is just driven, with collapser 8 one the same moving down, and the negative pressure valve unlatching.
When moving on lifting device is initial, active force has: epicoele 13 and the pressure reduction of cavity of resorption 15, the upwards thrust of pressure spring 21.Resistance has: 5 pairs of attraction forces of inhaling iron 7 of permanent magnet; Drive when together moving up when seal membrane 2 is raised device, active force has: the pressure reduction of epicoele 13 and cavity of resorption 15.Resistance has: 5 pairs of attraction force, seal membrane 2 resistances of inhaling iron 7 of permanent magnet.Be not difficult to find out thus, on lifting device, move past in the journey, the active force aspect, being greater than the later stage of initial stage, and resistance aspect, though increased the deformation resistance of seal membrane 2, but 5 pairs of suction of inhaling iron 7 of permanent magnet are reducing rapidly, and become quadratic relationship to reduce with distance, so, at whole lifting process, total change in resistance is little.When promptly starting, resistance is not to put on simultaneously on the lifting device, and the resistance that seal membrane 2 produces will lag behind a period of time, just put on the lifting device, and this resistance is again the maximum resistance that will really overcome.Like this, lifting device will produce more upwards acceleration, thus, can guarantee the reliability of negative pressure valve unlatching and high opening speed.
When negative pressure hole 11 and sourceof negative pressure cut-out, and while and atmosphere connection, epicoele 13 disappears with the pressure reduction of cavity of resorption 15, and under the restoring force of permanent magnet 5 attraction forces and seal membrane 2 self-deformations, lifting device moves down.Seal membrane 2 at first contacts with protruding weir 22, stops to move down.As mentioned above, the upper edge of step 20 and cavity 17 are gapped, and permanent magnet 5 can attract to inhale iron 7, drives whole lifting device and continues to move down.Pressure spring 21 is compressed.After suction iron 7 moves down and is pressed against damping pad 6, limited and stop to move, this moment, the upper edge and the cavity 17 of step 20 were still gapped, have only 21 pairs of seal membranes 2 of pressure spring to apply impacting force, therefore, the return error of seal membrane 2 can not have influence on the return of inhaling iron 7, promptly do not influence the return of lifting device, prepare for starting next time.
At the present invention,, following different embodiment can be arranged again with regard to different usage requirements:
Embodiment two to the return and the maintenance of lifting device, can not adopt the mode of permanent magnet attraction, and use return pressure spring 26 instead as shown in Figure 3.
Embodiment three as shown in Figure 4, for lifting device, when stroke was big, owing to be subject to the effective absorption distance of permanent magnet, the return of lifting device may be affected, and for this reason, preferably adopted the dual combination of return pressure spring 26 and permanent magnet 5.Return pressure spring 26 guarantees that lifting device gets back to permanent magnet 5 and effectively attract in the zones.
