Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.
Embodiment 1
As shown in figure 1, heap gate valve structure in disclosed in the present embodiment, including the valve seat support in valve body 1 and the inner chamber of valve body 1
Device, inner chamber includes valve body cavity of resorption 13, valve body epicoele, valve channel 4 and bonnet passage, and valve seat support meanss include two supports
Circle 2, two bracing rings 2 are respectively arranged on upstream and downstream, and bracing ring 2 is welded with valve body 1, the weldering of bracing ring 2 and the weld of valve body 1
Stitch 14 as shown in Figure 1.Bracing ring 2 is located at the top of valve body cavity of resorption 13, and the side wall of inner chamber has the anti-corrosion layer of built-up welding, such valve institute
There are flow-passing surface all heaps to be welded with corrosion resistant coating, corrosion-resistant effect is played comprehensively.The material of anti-corrosion layer is corrosion resistant alloy, as excellent
Choosing, corrosion resistant alloy includes nickel-base alloy.Preferably, the thickness of anti-corrosion layer is not less than 3mm.
The valve weight of large caliber flat plate gate valve is heavier, due to the limitation of FMT and cost, valve body 1 in the present embodiment
Using casting structure.Its structure of casting valve body is more irregular, and its top layer has the defects such as loose, slag inclusion, oxide skin during casting,
Inner chamber arm is polished to and sees that metallic luster is highly difficult, particularly intracavity bottom, directly built-up welding weld layer on the casting surfaces
Quality can not ensure, therefore body cavity must take into consideration machinability.As shown in Fig. 2 the inner chamber of the present embodiment valve body 1 includes A, B
All flow-passing surfaces in face are machinable.Inner chamber inner wall overlaying is resistance to again after all surface machinings contacted with medium in valve body 1
Corrosion layer, the qualified rear position welded with bracing ring 2, installation valve seat 3 is reprocessed after being welded.
Embodiment 2
The present embodiment and the difference of embodiment 1 are:As shown in figure 3, interior heap gate valve structure also include flashboard 5, bonnet 8,
Valve seat 3 and valve rod 10, bonnet 8 and valve body 1 are affixed, and support 11 and bonnet are affixed, and packing ring 7 is provided between bonnet 8 and valve body 1.Valve
The inwall of lid 8 has the anti-corrosion layer of built-up welding, forms bonnet excessively stream overlay cladding 9.All flow-passing surfaces of the present embodiment valve all heaps are welded with resistance to
Rotten coating, improves the corrosion-resistant effect of valve comprehensively.Flashboard 5 is in valve body 1 and positioned in two bracing rings 2
Between valve seat 3, the one end of valve rod 10 is connected with flashboard 5, and the other end of valve rod 10 passes bonnet 8.Further, flashboard 5 and bracing ring 2
Between be provided with valve seat 3, valve seat 3 be arranged on bracing ring 2 on.Flashboard 5 and tray 6 are affixed, and valve rod 10 drives flashboard 5 by tray 6
Move up and down and realize the keying of valve.
Due to being rich in elemental sulfur and other impurity in the medium in high sulfur-bearing operating mode, as shown in figure 4, the present embodiment is in support
Circle 2 in the mating surface of valve seat 3 with being provided with dust ring 12.Preferably, the mating surface of bracing ring 2 and valve seat 3 is cascaded surface.Not
When increasing dust ring 12, elemental sulfur and impurity are easily deposited at the bracing ring 2 and contact site C of valve seat 3, the sealing surface of valve seat 3 is caused
Can not be parallel with the sealing surface of flashboard 5, there is poorly sealed or even stuck phenomenon in valve.
The anti-corrosion layer effect of the anti-corrosion layer of the utility model valve body and bonnet prevents medium and valve body, bonnet to connect
Touch, improve the corrosion resistance of valve, to flow of media surface build-up welding anti-corrosion layer, effectively reduce the use of expensive resistant material
Amount, greatly reduces production cost.
