Abstract
The utility model provides a pressurize formula gate sealing device, includes that wing head bottom plate and the fixed connection of fixed connection on the gate at the overhead clamp plate of wing head bottom plate upper limb, is equipped with the stagnant water component between wing head bottom plate and the overhead clamp plate of the wing, the stagnant water component includes that water seal wing head and fixed connection at the stagnant water component head of the first end of the water seal wing, still include the thrust piston, and the piston rod fixed connection of thrust piston still is equipped with the thrust jar that is used for settling the piston head in the inside of water seal wing head in wing headstock board, the thrust jar is connected with the equipment of pressurizing, the utility model discloses when playing fine sealed effect, do not receive the influence of stagnant water component preparation error, in addition can not be because of high -pressure gas in certain some gathering and cut off stagnant water wing head.
Description
Technical field
The utility model relates to gate sealing water-stopping technical field, relates to a kind of pressurized type water gate sealing device.
Background technology
Adopt conventional " P " type sealing as the end of gate for Gate in prior art, side sealing, because gate dash pressure is large, span is large, band hydraulic pressure opens and closes frequent, and the water retaining facing of gate and sealing are arranged in hydraulic pressure side, can deflection deformation be there is in gate in dash generation, because " P " type sealing is in compressive state for a long time, and then be very easy to wearing and tearing, adopt telescopic Rubber water stop device afterwards, this antipriming due to be adopt air seal component is directly pressurizeed, due to be seal component adopt rubber make, and the molecule of air is less, so air can through the junction bottom water seal wing head and wing head when pressurising, and then pressurising air is run off, when running off too much, just well can not play the effect of sealing, the processing method of rubber is also had to be difficult to ensure that seal component is all unified shape, when pressurizeing to antipriming, due to shape disunity, make the pressurized situation of seal component pressure face and each contact position of moisture wing head different, and then make the air of high pressure can certain a bit on form cut-out power, especially in wing head weakness or place jaggy, water-proof wing head can cut off by this pressure-air.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of gate pressurized type water-stopping sealing device, while playing good sealing effectiveness, be not subject to seal component foozle on the impact of stagnant water effect, and water-proof wing head can not be cut off because gases at high pressure a bit assemble at certain.
To achieve these goals, the technical solution of the utility model is: a kind of pressurized type water gate sealing device, comprise the wing head base plate be fixedly connected on gate, with be fixedly connected on wing head base plate upper limb head top board, seal component is provided with between wing head base plate and wing head top board, described seal component comprises water seal wing head and is fixedly connected on the seal component end socket of the first end of the water seal wing, also comprise thrust piston, the piston rod of thrust piston is fixedly connected on the inside of water seal wing head, the thrust cylinder for settling piston head is also provided with in wing headstock plate, described thrust cylinder and pressurising equipment connection.
Further, described seal component and thrust piston are at least provided with two on gate.
Further, the end face of the piston head of described thrust piston is provided with groove.
Further, the piston head of described thrust piston is at least provided with two piston rings.
Further, described piston rod is arranged in one end of water seal wing head is swallow-tail form.
The technique effect after this structure is adopted to be: directly to adopt air to carry out filling pressure sealing to seal component to replace to piston and promote sealing by original, its mode avoids air and directly contacts with the direct of rubber seal, thus avoid rubber seal by air squeeze off may, and when carrying out pressurization to the skimble-scamble seal component of processing, due to be adopt piston promote seal move, for carrying out relative to directly adopting gas promoting, while playing good sealing effectiveness, avoid the possibility that water seal wing head is cut-off; Water element and thrust piston are at least provided with two and employing two piston rings on gate, and relative to employing one, its sealing effectiveness is better.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the view of the utility model when not working;
View when Fig. 2 is utility model works;
Fig. 3 is partial enlarged drawing of the present utility model.
Detailed description of the invention
As shown in Fig. 1 to 3: a kind of pressurized type water gate sealing device, comprise the wing head base plate 1 be fixedly connected on gate 5, with be fixedly connected on wing head base plate 1 upper limb head top board 8, seal component 4 is provided with between wing head base plate 1 and wing head top board 8, described seal component 4 comprises water seal wing head 42 and is fixedly connected on the seal component end socket 41 of water seal wing head 42 one end, also comprise thrust piston 7, the piston rod 73 of thrust piston 7 is fixedly connected on the inside of water seal wing head 42, the thrust cylinder 10 for settling piston head 71 is also provided with in wing headstock plate 1, described thrust cylinder 10 is connected with pressurising equipment 6.
Further, described seal component 4 and thrust piston 7 are at least provided with two on gate 5.
Further, the end face of the piston head 71 of described thrust piston 7 is provided with groove.
Further, the piston head 71 of described thrust thrust piston 7 is at least provided with two piston rings 72.
Further, described piston rod 73 is arranged in one end of water seal wing head 42 is swallow-tail form.
Embodiment: as shown in Figure 2: gate 5 pressurized type antipriming is when dash, pressurising equipment 6 is opened, air push piston 7 moves down, piston 7 promotes seal component end socket 41 and moves to sealing seat board 9, when air reaches certain pressure, and gate is not leaking, pressurising equipment 6 is quitting work, and carries out pressurize to its sealing.
As shown in Figure 1: gate 5 pressurized type antipriming is after dash, and pressurising equipment 6 pressure release, water seal wing head 42 recovers original state, and seal component end socket 41 moves up, and piston 7 moves up.
