Description
Technical field
The utility model is related to a kind of bolted bonnet (BB) forged steel split Wedge Gate Valves.
Background technology
Wedge Gate Valves is widely used in the every profession and trades such as petrochemical industry, electric power as a kind of typical valve class simple in structure.Traditional
Common gate valve is in order to compensate for the foozle of the sealing surface angle of wedge, and the structure of flashboard is frequently with elastic construction, conventional wedge-type double-gate
The component part of plate gate valve is more, structure is complex, and gate sealing surface is two parallel planes, and the sealing pair formed in this way is not easy reality
Existing, sealing generates leakage.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of bolted bonnet (BB) forged steel split Wedge Gate Valves.
The technical solution of the utility model is：A kind of bolted bonnet (BB) forged steel split Wedge Gate Valves, the interior setting of valve body
There are valve seat, left flashboard to be arranged in valve seat with right flashboard, valve body has the left sealing surface of valve body and the right sealing surface of valve body, left flashboard
There is the left tilted surface being adapted to the left sealing surface of valve body, right flashboard to have the right tilted surface being adapted to the right sealing surface of valve body, valve body for side
Inner cavity is provided with guide groove, and the left tilted surface of left flashboard and the right tilted surface of right flashboard are moved along guide groove；Valve rod is connected by flashboard frame
Left flashboard and right flashboard are connect, valve body is bolted with valve deck.
Further, the left sealing surface of the valve body and the angle of wedge of the right sealing surface of valve body are 20 ° ~ 25 °.
Further, it is provided with gasket between the valve body and valve deck.
Further, be provided with airtight and watertight padding structure between the valve rod and valve deck, airtight and watertight padding structure under upper according to
Secondary is upper seal support, Packing seat, filler, filler pressing sleeve, hold-down grid, and upper seal support is fixed on valve deck, and hold-down grid passes through
Bolt is fixed on valve deck.
Further, the valve body is all made of forging structure with valve deck.
The beneficial effects of the utility model are：The guiding rib update of valve body is designed as guide groove structure by the utility model,
The wedge-type double disc component of multiple part compositions is set to be reduced to two-piece or so two panels flashboard structure, hence it is evident that improve split wedge
The reliability of formula gate valve, improves properties of product.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is airtight and watertight padding structural schematic diagram.
Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings, the present embodiment is not constituted to this
The limitation of utility model.
It is convenient that sealing surface is repaired in order to more compensate foozle, Wedge type double gate board gate valve can be used.Such as figure
Shown in 1, a kind of bolted bonnet (BB) forged steel split Wedge Gate Valves, including valve body 1, valve seat 2, left flashboard 3, right flashboard 4, valve
The left sealing surface 5 of body, the right sealing surface 6 of valve body, left tilted surface 7, right tilted surface 8, valve rod 9, valve deck 10, gasket 11, bolt 12, upper seal support
13, Packing seat 14, filler 15, filler pressing sleeve 16, hold-down grid 17.
Valve seat 2 is provided in valve body 1, left flashboard 3 is arranged with right flashboard 4 in valve seat 1, and valve body 1 has the left sealing of valve body
Face 5 and the right sealing surface 6 of valve body, the angle of wedge of the right sealing surface of the left sealing surface 5 of valve body and valve body 6 are 20 ° ~ 25 °, and the one of left flashboard 3
There is the left tilted surface 7 being adapted to the left sealing surface of valve body, right flashboard 4 to have the right tilted surface 8 being adapted to the right sealing surface of valve body, close for side
When valve closing door, the left sealing surface 5 of valve body and the right sealing surface 6 of left tilted surface 7, valve body and the right tilted surface 8 of right flashboard 4 of left flashboard 3 generate
Self sealss power.Inner cavity is provided with guide groove in valve body 1, and the left tilted surface 7 of left flashboard 3 is transported with the right tilted surface 8 of right flashboard 4 along guide groove
It is dynamic, the rotation of left flashboard 3 and right flashboard 4 is prevented, the abrasion of the left sealing surface 5 of valve body and the right sealing surface of valve body 6 is reduced.
Valve rod 9 connects left flashboard 3 and right flashboard 4 by flashboard frame, and left flashboard 3 is done with right flashboard 4 under the driving of valve rod 9
It moves up and down.
Gasket 11 is provided between valve body 1 and valve deck 10.Valve body 1 is connect with valve deck 10 by bolt 12.
Valve body 1 is all made of forging structure with valve deck 10, and dense structure has prevented shrinkage cavity, the gas that casting valve body is susceptible to
The defects of hole, burning into sand；Valve body 1,10 surface of valve deck all process, and surface quality is good, good appearance.
For airtight and watertight padding structure setting between valve rod 9 and valve deck 10, airtight and watertight padding structure is followed successively by upper sealing under upper
Seat 13, Packing seat 14, filler 15, filler pressing sleeve 16, hold-down grid 17, upper seal support 13 are fixed on valve deck 10, hold-down grid
17 are bolted on valve deck 10.
Operation principle is：Valve rod pushes left flashboard, right flashboard to enter in the runner of valve body, and left flashboard is in valve flowing channel side
It pushes the sealing surface of right flashboard to press to the other side under the action of pressure medium, realizes the self sealss of runner.
The above descriptions are merely preferred embodiments of the present invention, is not used in limitation the utility model, this field skill
