Description
Technical field
It the utility model is related to a kind of flat gate valve, and in particular to a kind of high-temperature wearable flat plate shear gate valve.
Background technology
Gate valve is current industrial applicability and its a kind of extensive valve, and it is each that it is mainly used in chemical industry, electric power and urban construction etc.
Individual field.
Wherein Wedge Gate Valves is widely used because of the design of flashboard disengaging valve seat reduction mill resistance in its opening process, at present greatly
It includes valve body, flashboard and flashboard controller to most Wedge Gate Valves, the sealing surface of flashboard for by lower end towards the inclination in flashboard
Design, valve body are provided with the runner closed by flashboard or opened, and the valve coordinated with the wedge shaped sealing of flashboard is provided with runner
Seat.Flashboard controller is set with flashboard linkage, and it includes lifting the drive device of flashboard and connection drive device and wedge-shaped flashboard
Valve rod, by the drive device can make flashboard close and open valve body, play control action.
Although traditional Wedge Gate Valves sealing is good, it also has many weak points.Firstly, for different incomings
Pressure and the sealing effectiveness to be expanded with heat and contract with cold for different temperatures under state are different, do not accomplish to play different incoming pressure and temperature
To compensation effect；Secondly, wedge-type seal face matching design can be when opening gate valve, and flashboard separates with valve seat adheres to medium impurity
On valve seat, when closing gate valve, medium impurity is squeezed between flashboard and valve seat, sealing is reduced so as to wear valve seat
Property.
The content of the invention
In view of the deficienciess of the prior art, the purpose of this utility model is not to provide one kind to different incoming-flow pressures and not
It is synthermal to play sealing compensation effect, and can protect, clean the high-temperature wearable flat plate shear gate valve of valve seat.
To achieve the above object, the utility model provides following technical scheme：Controlled including valve body, flashboard and flashboard
Device, described valve body are provided with the runner closed by flashboard or opened, the valve seat coordinated with ram seal are provided with runner,
Flashboard controller is set with flashboard linkage, and it includes lifting the drive device of flashboard and the valve rod of connection drive device and flashboard,
It is characterized in that：Described flashboard includes the import flashboard and outlet flashboard relative to the movement of runner direction, described import flashboard
And the cavity being respectively arranged with the relative face of flashboard parallel to runner direction is exported, the cavity on described import flashboard is with going out
Cavity on mouth flashboard is provided with corresponding opening, compresses and is provided with import flashboard and outlet in relative described cavity
The spring that flashboard resets to corresponding valve seat, described import flashboard and outlet flashboard respectively and are relatively set with supply body heat
The stereomutation room of swollen shrinkage, mutual UNICOM between each described stereomutation room, and not with runner UNICOM.
By using above-mentioned technical proposal, flashboard is divided into two, and compression spring is provided between flashboard, by flashboard
Be squeezed in both sides on valve seat, there is provided pretightning force, make sealing relatively reliable, and for high pressure incoming, incoming have by flashboard to
The trend of media flow direction extruding, makes flashboard overall and is moved to flow direction, now, outlet flashboard offset with corresponding valve seat it
On, import flashboard is pressed to the movement of outlet flashboard side, and spring continues deformation and is pressurized, elastic force caused by spring by import flashboard towards with
Its for valve seat direction extrude, play compensating action.In switching process, flashboard and valve seat contact only carry valve by spring
The pretightning force of confession, therefore two sealing surface contact forces are small, abrasion is also small, so as to further increase the service life of valve.Except this
Outside, the design of stereomutation room is expanded with heat and contract with cold automatically for high/low temperature incoming, flashboard is mutually butted on valve seat, plays compensation
Effect, carrys out flow medium suitable for different temperatures.Valve seat easily make during open and close medium impurity be attached to valve seat it
On, in the presence of spring and stereomutation room, flashboard is mutually butted on valve seat all the time, and flashboard produces shearing in closing process
Power strikes off the medium impurity on valve seat, plays a part of protection, cleaning valve seat.
The utility model is further arranged to：Described import flashboard and outlet flashboard is provided with cavity and stereomutation
Room and the sealing of runner isolation, described sealing is annular in shape, and the compression of described sealing is arranged at import flashboard and outlet
Between flashboard, described import flashboard and outlet flashboard are respectively arranged with the seal groove coordinated with sealing installation.
By using above-mentioned technical proposal, cavity and stereomutation room are isolated by sealing with runner, using by flashboard
Internal enclosed construction, make medium and spring completely isolated, prevent flow media touches with spring interface from causing spring performance to change, remove
Outside this, the isolation of stereomutation room cause the change of stereomutation building volume will not with runner UNICOM and it is ineffective.
The utility model is further arranged to：Locating piece has been wholely set on described valve rod, has been set on described valve body
There is the locating surface on locating piece deformation trace, when described locating piece is mutually butted on locating surface, flashboard closed flow makes
Runner is in closed mode.
By using above-mentioned technical proposal, the design of locating piece, make flashboard will not be because excessive descent is led in closing process
Flashboard is caused to depart from valve seat, so as to lose sealing effectiveness.In addition, under valve seat stops when locating piece is mutually butted on locating surface
Drop, valve seat will not be produced and decline collision body base, play a part of protecting flashboard and valve body.
The utility model is further arranged to：Valve body is provided with the valve rod punched out passed for valve rod, and described valve rod is worn
Filler is provided with portalling, described filler is squeezed between valve body and valve rod, and described valve body punched out is located at below filler
The filler keeper for filler positioning is provided with, the filler pressure moved along valve body punched out is provided with described valve body punched out
Lid, described gland are squeezed in above filler, and described gland is provided with and valve body spiral shell along valve body punched out direction
The bolt that line coordinates, the head of the bolt above gland with offseting.
By using above-mentioned technical proposal, the design of filler, valve inner space and the external world are effectively sealed, makes integral valve
Body will not produce leakage phenomenon.The design of packaged type gland, sealing is even more played to different filler materials, depth and is made
With.Bolt-connection design makes filler squeezed tight play double sealing effect between valve body and valve rod, sealing more may be used
Lean on, the reliable sealing of the filler effectively ensured under any circumstance.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the sectional view of the utility model embodiment.
