Description
Technical field
The utility model relates to ultrahigh temperature gate plate valve field, particularly relates to a kind of ultrahigh temperature gate plate valve valve body double layer construction.
Background technique
For flue-gas temperature more than 1000 DEG C, tunnel gas regulator site that sealing requirements is very high, extensively adopt flashboard pattern valve at present.Generally adopt on housing according to actual conditions (flue-gas temperature, dust concentration, working pressure etc.) valve body inner lining structure and weld " Y " type palladium nail, directly beat the heat-resistant, wear-resistant castable of different-thickness, make easier, physical dimension easily ensures, wear-corrosion resistance, but due to castable characteristic, heat insulation property effect is bad, flue-gas temperature loss is excessive, cause boiler output not enough, high-temperature dust-containing flue gas makes valve body produce obviously distortion simultaneously, causes flashboard channel deformation, there will be flashboard stuck phenomenon time serious.
Summary of the invention
The purpose of this utility model is the shortcoming overcoming prior art, a kind of ultrahigh temperature gate plate valve valve body double layer construction is provided, make ultrahigh temperature gate plate valve valve body under high-temperature, high abrasion adverse condition, valve body structure does not produce obvious distortion, valve interior surface erosion resistance is strengthened, and achieve the requirement of valve body heat-insulation and heat-preservation, substantially reduce the number thermal loss.
For solving above technical problem, the technical solution of the utility model is: a kind of ultrahigh temperature gate plate valve valve body double layer construction, its difference is: it comprises tabular housing, described casing lining is provided with heatproof calcium silicate board, described calcium silicate board lower surface adopt Bond and housing to carry out boning and pass through to compress anchoring piece and housing fastening, calcium silicate board upper surface sprays marine glue, calcium silicate board top is provided with palladium nail, described palladium nail welds with described compression anchoring piece pressing plate, palladium nail surface is wiped with bituminous paint, many the wooden laths vertically laid also are provided with above calcium silicate board, calcium silicate board top forms LIFT after beating castable by the peripheral cast template arranged.
By above technological scheme, described palladium nail is " V " type structure.
By above technological scheme, interval 700 ~ 900mm between described wooden lath.
By above technological scheme, described housing is welded by low-alloy structural steel.
Contrast prior art, beneficial features of the present utility model is as follows:
1), valve inner adopts double-layer heat insulation abrasion-proof structure, and housing adopts low-alloy structural steel plate to be welded, and postwelding Shot Blasting, effectively eliminates welding stress, material good welding performance, and intensity is high;
2), valve body internal layer lays heatproof calcium silicate board, the features such as calcium silicate board has good insulating, insulation, high temperature do not fire, high temperature smoke-free and tasteless, lightweight, the life-span long, cutting simple installation;
3), valve body skin cast heat-resistant, wear-resistant high-strength castable, castable is firm, heatproof, wear-resisting, effectively can resist the abrasion of ash-laden gas;
4), valve body structure do not produce obvious distortion, and valve interior surface erosion resistance is strengthened, and do not produce stuck phenomenon when flashboard runs, emphasis achieves the requirement of valve body heat-insulation and heat-preservation, substantially reduce the number thermal loss, improves systems generate electricity efficiency and service life of equipment.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Wherein: 1-housing, 2-calcium silicate board, 3-Bond, 4-compress anchoring piece, 5-marine glue, 6-palladium nail, 7-bituminous paint, the wooden lath of 8-, 9-cast template, 10-LIFT.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail below by embodiment.
Please refer to Fig. 1, the utility model embodiment ultrahigh temperature gate plate valve valve body double layer construction, its difference is: it comprises tabular housing 1, described housing 1 liner is provided with heatproof calcium silicate board 2, described calcium silicate board 2 lower surface adopt Bond 3 and housing 1 to carry out boning and pass through to compress anchoring piece 4 and housing 1 fastening, calcium silicate board 2 upper surface sprays marine glue 5, calcium silicate board 2 top is provided with palladium nail 6, described palladium nail 6 welds with described compression anchoring piece 4 pressing plate, palladium is followed closely 6 surfaces and is wiped with bituminous paint 7, many the wooden laths 8 vertically laid also are provided with above calcium silicate board 2, calcium silicate board 2 top is by forming LIFT 10 after peripheral cast template 9 dozens of castables arranged.
Concrete, palladium nail is " V " type structure.
Preferably, interval 700 ~ 900mm between described wooden lath.
Preferably, described housing is welded by low-alloy structural steel.
In the utility model embodiment, concrete processing scheme is:
1) described housing 1 adopts low-alloy structural steel to make, and postwelding carries out Shot Blasting;
2) described housing 1 liner adopts heatproof calcium silicate board 2(metal housing surface to clean out);
3) described calcium silicate board 2 adopts adhesive special 3 to bond with housing;
4) described calcium silicate board 2 makes by compressing anchoring piece 4(refractory steel) tightly join with housing 1;
5) fastening good its surface sprinkling marine glue 5 rear of described calcium silicate board 2, plays water proof protective action;
6) described valve body refractory steel makes " V " type palladium nail 6, welds with compression anchoring piece 4 pressing plate;
7) described palladium is followed closely 6 surfaces and is spread bituminous paint 7, is vertically laid on (reserved dilatation joint, interval about 800mm) above calcium silicate board 2 with wooden lath 8;
8) described valve body installs cast template 9;
9) described valve body is beaten castable according to cast template 9 moulding and is formed LIFT 10;
10) curing in the mold and demoulding maintenance.
The double-layer heat insulation wear-resistant liner structure that the utility model technology adopts, significantly reduce the impact of high-temperature flue gas on gate valve, decrease the loss of flue-gas temperature, observe through practice, flue gas is in the situation of degree more than 1000, and obvious crackle and obscission do not appear in valve body castable, valve body is not because high temperature deformation causes flashboard stuck, the outside measured temperature of valve body is only about 70 DEG C, and site environment temperature significantly reduces, and meets energy-saving and cost-reducing and usage requirement.
