Description
Technical field
The utility model belongs to valve field, is related to a kind of gate valve, and in particular to a kind of bellows Wedge Gate Valves.
Background technology
Wedge action valve is one kind of gate valve, because its sealing surface and vertical center line into certain angle be two sealing surfaces into wedge
Shape and gain the name.Parallel gate valve is different from, wedge action valve also has wedge-shaped single flashboard valve.Two sealings of the most frequently used wedge gate valve
Face forms wedge shape, and key groove is different with valve parameter, and usually 50.The flashboard of Wedge Gate Valves can be integrally formed, and be called
Rigid flashboard；Can also make can produce the flashboard of micro-deformation, to improve its manufacturability, make up sealing surface angle processed
Caused deviation in journey, this flashboard are called flexible disc.
At present, Wedge Gate Valves is widely used in electric power, waterpower, petrochemical industry, metallurgy industry.Existing Wedge Gate Valves is typically to have
Valve body, valve seat, flashboard, valve rod, bonnet, support, handwheel etc. are formed, and filler position easily leaks, and is not suitable for special operation condition
The requirement of low leakage.So, the functional reliability of Wedge Gate Valves is reduced, shortens the service life of valve.
The content of the invention
The purpose of the utility model is to provide a kind of bellows Wedge Gate Valves for overcome the deficiencies in the prior art.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of bellows Wedge Gate Valves, it includes：

Into the flashboard of sealing pair；
Seal assembly, the seal assembly include being covered on bottom flange at the top of the accommodating chamber, sealed set in described
Bonnet, at the top of first branch pipe of the first branch pipe, sealed set at the top of bottom flange, lower end are connected with the flashboard
And upper end is through the bottom flange, the valve rod of the first branch pipe and bonnet, lower end is welded on the valve rod and upper end is welded on
The bellows of the bonnet, bottom and the packing seal mechanism on the bonnet,；
Governor motion, the governor motion include being arranged at the top of the packing seal mechanism and being enclosed on outside the valve rod
Second branch pipe, on second branch pipe and the gear-box that is connected with the valve rod and on the gear-box
Handwheel.
Optimally, the first gasket seal, first branch pipe and institute are installed between the accommodating chamber and the bottom flange
State and the second gasket seal is installed between bonnet,.
Optimally, the packing seal mechanism includes being embedded at the filler in the bonnet, and being set on the valve rod
The filler that pad, is arranged on the Packing seat, the filler pressing sleeve being pressed at the top of the filler, it is pressed at the top of the filler pressing sleeve
Hold-down grid and through the hold-down grid and the stud that is connected with the bonnet,.
Because above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Bellows Wedge Gate Valves, coordinated by using valve system, seal assembly and governor motion of specific structure etc., so can
Moved up and down by rotation hand wheel band ovable valve stem and flashboard, realize the unlatching of valve, close；And carried out using metal bellows
Sealing, it is ensured that inclusion seal at valve rod, improve the sealing property and work stability and reliability of valve.
