Abstract
The utility model provides a gage valve, which includes a rectangular valve body and a rectangular flashboard, wherein the valve body is provided with a media passage; the flashboard is set inside the valve body movably for opening or closing the media passage. The gate valve is characterized in that the bottom of the valve body is linked with a board member firmly; the board member is provided with a transverse lever that parallel to the flashboard movably; two ends of the transverse lever are connected with the flashboard through a valve rod; middle of the transverse lever is connected with a drive set that is used for driving it to move upward or downward vertically along the board member. The flashboard provided in the utility model is capable of providing reliable full media passage.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of gate valve.
Background technique
Gate valve is an a kind of valve that supplies 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; Have medium channel on the valve body, the movable inside that is arranged on valve body of flashboard is used to open or close medium channel, at the two ends of flashboard drive unit is set respectively usually 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, thereby to such an extent as to cause the medium channel of flashboard run-off the straight on can't the complete shut-down gate valve, along with the continuous progress of 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, only the horizontal intermediate portion of flashboard is connected the inclination of easy equally generation 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, existing technology mainly exists flashboard to be prone to and the defective of complete shut-down medium channel and problem reliably.
Summary of the invention
The utility model technical problem to be solved provides a kind of flashboard gate valve of complete shut-down medium channel reliably.
For solving the problems of the technologies described above; The utility model provides a kind of gate valve; Comprise rectangle valve body and rectangle flashboard, have medium channel on the said valve body, the movable inside that is arranged on said valve body of said flashboard is used to open or closes said medium channel; The bottom of said valve body is fixedly connected with a plate; The movable cross bar that parallels with said flashboard that is provided with on the said plate, the two end part of said cross bar are connected with said flashboard through valve rod, and the intermediate portion of said cross bar is connected with one and is used to drive the vertical mobile downward or upward drive unit of its said plate in edge.
Said plate is the rectangle plate; The left end of said rectangle plate and right-hand member are respectively arranged with left rail and the right guide rail perpendicular with said flashboard; Movable respectively left slider and the right slide block of being provided with on said left rail and the said right guide rail; Said left slider is connected with said flashboard through said valve rod with said right slide block, and said left slider is connected through said cross bar with said right slide block.
Said drive unit is the cylinder that is fixedly installed on the said plate.
The sidewall of said plate is provided with two vents that communicate with cylinder.
Compared with prior art, the beneficial effect of the utility model is:
Because a kind of gate valve of the utility model 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 in the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model.
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 accompanying drawing and embodiment the utility model is explained further details
Referring to shown in Figure 1; A kind of gate valve comprises rectangle valve body 10 and rectangle flashboard (not shown), has the medium channel 14 of rectangle on the valve body 10; The movable inside that is arranged on valve body 10 of flashboard is used to open or closes medium channel 14; The bottom of valve body 10 is fixedly connected with a plate 16, and this plate 16 is the rectangle plate, and the left end of this rectangle plate 16 and right-hand member are respectively arranged with the left rail 18 and 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 through valve rod 26 with right slide block 24, and left slider 22 is connected with the cross bar 28 of right slide block 24 through cross setting, and 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 is 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 through driving cross bar 28 two ends that are passed to flashboard that driving force is even, synchronous during use, thereby can not cause flashboard to tilt, to such an extent as to can make flashboard complete shut-down medium channel.
To sum up, the utility model flashboard is the complete shut-down medium channel reliably.
The above is merely the preferred embodiments of the utility model; The protection domain of the utility model does not exceed with above-mentioned mode of execution; As long as the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or changed, all should include in the protection domain of putting down in writing in claims.
