Description
Technical field
The utility model belongs to gate valve technical field, and in particular to a kind of Wedge type double gate board gate valve.
Background technology
Gate valve is a kind of most common keying valve, and the medium in pipeline is connected or block using flashboard.The operation of gate valve
Torque can increase and increase with the bore of valve, so in large diameter pipeline, the operational torque of gate valve can accordingly increase, this
The requirement increase of control device to controlling stem movement is a lot, and the keying of gate valve can also become to be not sufficiently stable.It is existing
Heavy-caliber gate valve is typically chosen wedge-type double-gate harden structure, can reduce the operational torque of valve, but can not but meet bigger mouth
The pipeline requirement in footpath.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of Wedge type double gate board gate valve.
Technical solution adopted in the utility model is as follows：A kind of Wedge type double gate board gate valve, including valve body, bonnet, valve rod,
Flashboard, the control device for controlling stem movement, the flashboard are installed respectively including wedge-type flashboard frame, the wedge-type flashboard frame or so
There are left flashboard, right flashboard, the wedge-type flashboard frame is connected with valve rod, and the valve body is equipped with a bypass in the both sides of flashboard
Mouthful, two by-pass ports are provided with by-passing valve by external pipe UNICOM, external pipe.
The valve body lower end is connected with base support.
The valve body lower end is provided with base portion, is connected by screw between the base portion and base support.
Adjustment plate is provided between the base portion and base support.
The bonnet is provided with water injection hole.
A plurality of reinforcement is equipped with the valve body, bonnet.
The control device is electric device.
The beneficial effects of the utility model are as follows：When valve opening torque is larger, by-passing valve can be first opened, to reduce
Pressure differential at left and right sides of flashboard, so as to reduce the unlatching moment of valve.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of another angle of the utility model.
Fig. 3 is base portion and the connection diagram of base support.
In figure, 1, valve body；101, by-pass port；102, base portion；2, bonnet；201, water injection hole；3, valve rod；4, flashboard；
401, wedge-type flashboard frame；402, left flashboard；403, right flashboard；5, control device；6, by-passing valve；7, base support；8, adjustment plate.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model can be better described.
A kind of Wedge type double gate board gate valve, including valve body 1, bonnet 2, valve rod 3, flashboard 4, the control device for controlling stem movement
5, the flashboard 4 includes wedge-type flashboard frame 401, and the wedge-type flashboard frame 401 or so is separately installed with left flashboard 402, right flashboard
403, the wedge-type flashboard frame 401 is connected with valve rod 3, it is characterised in that：The valve body 1 is equipped with one in the both sides of flashboard 4
By-pass port 101, two by-pass ports 101 are provided with by-passing valve 6 by external pipe UNICOM, external pipe.When valve opening torque
When larger, by-passing valve can be first opened, to reduce the pressure differential at left and right sides of flashboard, so as to reduce the unlatching moment of valve.
The lower end of valve body 1 is connected with base support 7.To ensure the height of valve flowing channel center to baseplane
The lower end of valve body 1 is provided with base portion 102, is connected by screw between the base portion 102 and base support 7.
It is connected by screw, base support can be removed.
Adjustment plate 8 is provided between the base portion 102 and base support 7.Adjustment plate can be added to adjust valve flowing channel
The height of center to baseplane adapts to the height of pipeline.
The bonnet 2 is provided with water injection hole 201.It is interior because the water injection hole of blind plate is smaller when valve makes a strength test
Time required for chamber fills water is longer, so water injection hole is also provided with bonnet, to reduce water injection time.
A plurality of reinforcement is equipped with the valve body 1, bonnet 2.To improve its intensity.
The control device 5 is electric device.Output torque is big.
A kind of embodiment of the present utility model is the foregoing is only, is not used for limiting the scope of protection of the utility model；
The scope of protection of the utility model is limited by the claim in claims, and it is every made according to utility model it is equivalent
Change and modification, all within the protection domain of the utility model patent.
