Abstract
The invention discloses a gate valve which comprises a rectangular valve body and a rectangular gate plate; the valve body is provided with a medium channel; and the gate plate is movably arranged in the valve body and is used for opening or closing the medium channel. The gate valve is characterized in that the bottom part of the valve body is fixedly connected with a plate piece; the plate piece is movably provided with a transverse rod which is parallel with the gate plate; two end parts of the transverse rod are connected with the gate plate through a valve rod; and the middle part of the transverse rod is connected with a driving device which is used for driving the transverse rod to move upwards or downwards along the plate piece. The gate plate provided by the invention can fully close the medium channel reliably.
Description
Technical field
The present invention relates to a kind of valve, relate in particular to a kind of gate valve.
Background technique
Gate valve is a kind of the valve for the usefulness of the medium operation on standard-sized sheet or all kinds of delivering pipes of complete shut-down or the equipment; present gate valve of the prior art mainly comprises rectangle valve body and rectangle flashboard; has medium channel on the valve body; the inside that is arranged on valve body of flashboard activity is used to open or close medium channel; usually at the two ends of flashboard drive unit is set respectively for easy to operate; thereby realize opening automatically or closing of flashboard; but usually can be owing to be positioned at the driving flashboard that the drive unit at flashboard two ends can't be synchronous fully; to such an extent as to thereby cause the medium channel of flashboard run-off the straight on can't the complete shut-down gate valve; continuous progress along with science and technology; occurred a kind of at the horizontal intermediate portion connection of flashboard drive unit; though this kind mode can overcome two defective and the problems that the drive unit synchronism is relatively poor that adopt; but only the horizontal intermediate portion of flashboard is connected the same inclination that easily produces flashboard with drive unit when the length of flashboard is longer; to such an extent as to the medium channel on can't the complete shut-down valve body; in sum, prior art mainly exists flashboard easily to tilt and the defective of complete shut-down medium channel and problem reliably.
Summary of the invention
Technical problem to be solved by this invention provides a kind of flashboard gate valve of complete shut-down medium channel reliably.
For solving the problems of the technologies described above, the invention provides a kind of gate valve, comprise rectangle valve body and rectangle flashboard, has medium channel on the described valve body, the inside that is arranged on described valve body of described flashboard activity is used to open or closes described medium channel, the bottom of described valve body is fixedly connected with a plate, the movable cross bar that parallels with described flashboard that is provided with on the described plate, the two end part of described cross bar are connected with described flashboard by valve rod, and the intermediate portion of described cross bar is connected with one and is used to drive it along the vertical drive unit that moves downward or upward of described plate.
Described plate is the rectangle plate, the left end of described rectangle plate and right-hand member are respectively arranged with left rail and the right guide rail perpendicular with described flashboard, movable respectively left slider and the right slide block of being provided with on described left rail and the described right guide rail, described left slider is connected with described flashboard by described valve rod with described right slide block, and described left slider is connected by described cross bar with described right slide block.
Described drive unit is the cylinder that is fixedly installed on the described plate.
The sidewall of described plate is provided with two vents that communicate with cylinder.
Compared with prior art, beneficial effect of the present invention is:
Because a kind of gate valve of the present invention only adopts a drive unit driving cross bar that is arranged on the cross bar intermediate portion to move up or down, when cross bar moves can with driving force even, synchronous be passed to the two ends of flashboard through valve rod, thereby can not cause flashboard to tilt, so flashboard complete shut-down medium channel reliably among the present invention.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Among the figure: valve body 10, medium channel 14, plate 16, left rail 18, right guide rail 20, left slider 22, right slide block 24, valve rod 26, cross bar 28, cylinder 30, vent 32, mounting hole 33.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details
Referring to shown in Figure 1, a kind of gate valve, comprise rectangle valve body 10 and rectangle flashboard (not shown), the medium channel 14 that has rectangle on the valve body 10, the inside that is arranged on valve body 10 of flashboard activity is used to open or closes medium channel 14, the bottom of valve body 10 is fixedly connected with a plate 16, this plate 16 is the rectangle plate, the left end of this rectangle plate 16 and right-hand member are respectively arranged with left rail 18 and the right guide rail 20 perpendicular with flashboard, on left rail 18 and the right guide rail 20 with any known mode movable respectively be provided with left slider 22 and right slide block 24, this left slider 22 is connected with flashboard by valve rod 26 with right slide block 24, left slider 22 is connected with the cross bar 28 of right slide block 24 by cross setting, the intermediate portion of cross bar 28 is connected with one and drives the cylinder 30 that cross bar moves downward or upward, the bottom that is arranged on cross bar that this cylinder 30 is vertical, the sidewall of rectangle plate 16 is provided with two vents 32 that communicate with cylinder 30, thereby the effect of this vent 32 is to change the manner of execution of cylinder 30 for cylinder 30 provides multiple ventilating mode, preferably be provided with a plurality of mounting holes 33 at valve body 10 upper edge medium channels 14, the effect of this mounting hole 33 is can be with valve body 10 firm being connected with pipe fitting or other fixed components, cylinder 30 is even with driving force by driving cross bar 28 during use, the synchronous two ends that are passed to flashboard, thereby can not cause flashboard to tilt, to such an extent as to can make flashboard complete shut-down medium channel.
To sum up, flashboard of the present invention is the complete shut-down medium channel reliably.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned mode of execution; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
