The specific embodiment
Please refer to Fig. 1 to Fig. 4, a preferred embodiment of a kind of draining valve sealing mechanism, described a kind of draining valve sealing mechanism, it comprises a valve body 100, a counterweight keg float 200, a sealing keg float 300, a pressing piece 400.
Described valve body 100 has outfall 110, and it is provided with cavity 120 and runs through the inside and outside perforation 130 of cavity 120.In the present embodiment, described valve body 100 also is provided with a rotating shaft 140.
In the present embodiment, described valve body 100 also is equiped with a water proof cover, the water proof cover comprises the perisporium 162 of a roof 161 and affixed roof 161, form described cavity 120 between roof 161 and the perisporium 162, roof 161 is offered described perforation 130, and described rotating shaft 140 is installed in roof 161 and is positioned at the side of perforation 130.
In the present embodiment, described valve body 100 also is installed with a dividing plate 150, and the roof 161 of described water proof cover abuts against dividing plate 150 times.
Described counterweight keg float 200, its activity is installed in the valve body 100.
Described sealing keg float 300 can seal or leave outfall 110, and its activity is installed in cavity 120.
Described pressing piece 400 can open or close perforation 130, and its rotation is installed in the valve body 100 and be in transmission connection counterweight keg float 200 and sealing keg float 300.
In the present embodiment, described pressing piece 400 comprises that an axle sleeve 410, can open or close perforation 130 pressure release sheet 420, be in transmission connection second push rod 440 of sealing keg float 300 of first push rod 430 and of counterweight keg float 200 that is in transmission connection, described pressure release sheet 420, first push rod 430 and second push rod 440 be affixed axle sleeve 410 respectively, and described axle sleeve 410 is socketed in the rotating shaft 140.
In the present embodiment, described pressure release sheet 420 is provided with a balancing weight 421.
In the present embodiment, first push rod 430 and pressure release sheet 420 all are positioned on the roof 161 of water proof cover, and second push rod 440 is positioned at cavity 120.
In the present embodiment, this drain valve structure also comprises the driving member of an affixed counterweight keg float 200, and this driving member is positioned on first push rod 430 and its terminal corresponding described first push rod 430.
In the present embodiment, described driving member is a drive link 500, and described drive link 500 ends are provided with a flat part 510 vertical with drive link 500, these flat part 510 corresponding described first push rods 430.
Its operating principle is as follows:
As shown in Figure 1, draining valve is in original state, be that counterweight keg float 200 is in float state, drive link 500 leaves first push rod 430, sealing keg float 300 sealing outfall 110, and closing perforation 130, first push rod 430 at pressure release sheet 420 under the effect of balancing weight 421 abuts against under the roof 161 of water proof cover away from roof 161, the second push rods 440 of water proof cover.
As shown in Figure 2, draining valve is in hull-borne, counterweight keg float 200 still is in float state at this moment, drive link 500 does not contact first push rod 430 yet, sealing keg float 300 upwards floats and leaves outfall 110, the space of cavity 120 is more and more littler, and pressure release sheet 420 is closed perforation 130, first push rod 430 and abutted against under the roof 161 of water proof cover away from roof 161, the second push rods 440 of water proof cover.
As shown in Figure 3, the draining valve draining finishes, counterweight keg float 200 loss of buoyance and falling, driving drive link 500 moves down, flat part 510 contact first push rods 430 and drive first push rod 430 and rotate counterclockwise until first push rod 430 and conform to roof 161, this moment, pressure release sheet 420 left perforation 130 so that cavity is inside and outside connects with the pressure in the balance cavity, and second push rod 440 is rotated away from roof 161 and is resisted against on the sealing keg float 300 and drives that sealing keg float 300 descends so that sealing keg float 300 sealing outfall.Because pressure and extraneous balance in the cavity make the counterweight of counterweight keg float 200 need not just can drive too greatly 300 declines of sealing keg float, draining valve is compact more, and cost is lower.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
