Abstract
The utility model relates to a wear-resistant slurry-discharging gate valve, which comprises a valve body, a pressure plate, a support, a hand wheel and a valve stem. The straight-through valve body is made of a seamless steel tube, two ends of the valve body are provided with outer flanges, the inner cavity of the valve body and the surface of a gate plate are provided with hard alloy welded layers by means of surfacing. The valve body is in straight-through form, the gate plate is flat, cavities are omitted, thereby the shortage that accumulated dust results in insensibility of a switch is overcome, wear resistance of the valve is increased and the service life of the valve is prolonged by the aid of the hard alloy welded layers, and therefore, the wear-resistant slurry-discharging gate valve is widely applicable to pipe systems for discharging sludge, slag and the like in power plants, mines, oilfield industries.
Description
Technical field
The utility model relates to the valve that uses water as on the carrier conveying solid substance material pipeline, especially relates to a kind of wear-resisting plasma discharge gate valve.
Background technique
Industrial and mining enterprise extensively adopt the various solid, powdery materials of phase flow pipeline hydraulic transportation, are used to carry various slag slurries as metallurgy industry; Mining utilizes line transportation raw material ore deposit, concentrate, mine tailing slurry; The power station is starched with line transportation fine coal; Hydraulic department line transportation silt etc.These slurries are all great than general flowing fluid ratio, thickness and be suspended with many solid matters, therefore in output procedure pipe-line system had stronger abrasion requirement.At present, the gate valve that is used for thermal power plant, mine, cement, chemical industry deslagging all is to be made of devices such as valve body, adpting flange, flashboard, restrictor bars, its valve body has cavity in the middle of mostly being closed at both ends, so easy dust stratification in the valve body, be obstructed when causing the flashboard switch, valve switch is dumb, and serious wear, needs frequent maintain and replace.
The model utility content
To be solved in the utility model is the easy dust stratification of gate valve, and valve switch is ineffective, and serious wear needs technical problems such as frequent maintain and replace.
At the problem that prior art exists, the technical solution adopted in the utility model is:
A kind of wear-resisting plasma discharge gate valve is made of valve body, pressing plate, flashboard, support, handwheel, valve rod, and described valve body is a through state, is made by seamless steel pipe, and two ends are equipped with outward flange; At body cavity and valve plate surface overlaying the cemented carbide weldering is arranged.
The beneficial effects of the utility model are:
Valve body of the present utility model is that through state is made by seamless steel pipe, does not have the cavity position, and flashboard is for directly tabular, so medium is not easy deposition, valve opening is closed flexibly; Body cavity and valve plate built-up welding have cemented carbide powder, and corrosion-proof wear has more prolonged working life of valve, therefore, extensively is suitable for pipe-line systems such as power plant, mine, oilfield applications spoil disposal deslagging and uses.
Description of drawings
Fig. 1 is a plan view of the present utility model;
Fig. 2 is a left view of the present utility model;
Among the figure: 1 is that valve body, 2 is that pressing plate, 3 is that flashboard, 4 is that support, 5 is that handwheel, 6 is that valve rod, 7 is the cemented carbide layer.
Embodiment
As shown in Figure 1, 2, a kind of wear-resisting plasma discharge gate valve of the utility model, constitute by valve body 1, pressing plate 2, flashboard 3, support 4, handwheel 5, valve rod 6, it is in conjunction with identical with common gate valve, difference is that valve body 1 is a through state, is made by seamless steel pipe, and two ends are equipped with outward flange, be valve body 1 the whole sealing surface diameter one of inner chamber to, do not exist the depression position.Flashboard 3 also is not easy to stockpile medium for directly tabular, has overcome because dielectric deposition influences the problem of valve switch, thereby reaches open and close purpose flexibly.
On the surface of the bore seal face of valve body 1 and flashboard 3, increased cemented carbide layer 7 in addition, improved the wear resistance of gate valve, can effectively increase the service life.
Claims (1)
1. a wear-resisting plasma discharge gate valve is made of valve body, pressing plate, flashboard, support, handwheel, valve rod, it is characterized in that described valve body is a through state, is made by seamless steel pipe, and two ends are equipped with outward flange; At body cavity and valve plate surface overlaying the cemented carbide layer is arranged.
