Description
Technical field
The utility model relates to valve technology field, particularly a kind of gate valve.
Background technique
Gate valve makes open-shut device with flashboard and move along valve seat axes normal direction, to realize the valve of switching motion.The major advantage of gate valve is that runner is unobstructed, and fluid resistance is little, and open and close torque is little; Major defect is that sealing surface easily abrades, and opening and closing time is longer, the bodily form and weight larger.The application of gate valve on pipeline is very extensive, is suitable for manufacturing large bore valves.Gate valve is generally used for blocking fluid, should not be used for adjust flux.Because when gate valve is in half-open position, flashboard can make sealing surface destroy by fluid erosion and impact, also can produce vibration & noise.
The working life of gate valve is in the market not long, comparatively requires great effort, and easily wear and tear during operation, often there will be the phenomenon of leakage.
Model utility content
In order to solve the problems of the technologies described above, the purpose of this utility model be to provide a kind ofly to operate easily, good airproof performance, the Novel Brake Valve in raising working life.
The technical solution of the utility model is: a kind of gate valve, comprising: valve body, and described valve body is provided with entrance point and outlet end, entrance point one side sealing; Valve seat, is positioned at valve flowing channel; Valve gap, described valve gap is fixed on valve body; Valve rod, described valve rod is through described valve gap, Gland; Filler, filler compresses by Gland; Handwheel, is positioned at the upper end of valve rod; Spool, is positioned at the lower end of valve rod, and shape is reverse frustoconic; Flap arrangement, be made up of flashboard and adjustment plate, adjustment plate lower end is semicircular arc, jointly forms circle with entrance point.
Further, described valve outlet bottom portion offers slag exhausting mouth, and the shape of slag exhausting mouth is wedge shape.Owing to have employed wedge shape, thus relative to other shape, can make valve body from bottom to outlet(discharge) flange, form the runner not having steep shape projection, can resistance be reduced, pre-preventing deposit, alleviate the wearing and tearing reducing valve body.
Further, described adjustment plate has an inclined-plane.
Further, described valve stem seal adopts the stuffing box packing of Expanded graphite, ensures that medium does not leak from valve rod.
Further, also comprise support, support is positioned at the outside of valve rod.
Further, sealing surface weld deposit Si Taili cemented carbide, adopts above-mentioned material can make valve energy resistance to erosion, corrosion-resistant and raising life-span.
Further, described spool adopts metallic material to make.
The utility model beneficial effect is: owing to taking a side sealing at entrance point, instead of two-side sealing, so can solve valve outlet because sealing and the flow resistance that causes; Adjustment plate lower end is set to semicircular arc, and jointly form circle with entrance point, such arranging can reduce jam, advantageous flow, can reduce the wearing and tearing in ram seal face; The shape of spool is set to reverse frustoconic, compares with other shape, its sealing area is larger, and the sealing effect of generation is better, above-mentioned ensure that the utility model operation easily, good airproof performance, improve working life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with Figure of description, the utility model is described in further detail.The term used in the present embodiment only for description specific features, is not intended to be limited.
As shown in Figure 1, a kind of gate valve, comprising: valve body 1, and described valve body 1 is provided with entrance point 12 and outlet end 13, entrance point 13 1 side sealing; Offer slag exhausting mouth bottom valve outlet end 13, the shape of slag exhausting mouth is wedge shape; Valve seat 2, is positioned at valve body 1 runner; Valve gap 3, described valve gap 3 is fixed on valve body 1; Valve rod 4, described valve rod 4 is through described valve gap 3, Gland 5; Filler 6, filler 6 compresses by Gland 5, and valve rod 4 seals and adopts Expanded graphite as stuffing box packing; Support 10, support 10 is positioned at the outside of valve rod 4; Handwheel 7, is positioned at the upper end of valve rod 4; Spool 8, is positioned at the lower end of valve rod 4, and shape is reverse frustoconic, adopts metallic material to make; Flap arrangement, be made up of flashboard 91 and adjustment plate 92, adjustment plate 92 lower end is semicircular arc, jointly forms circle with entrance point 12, and adjustment plate 92 has an inclined-plane.
Valve sealing surface build-up welding Si Taili cemented carbide, adopts above-mentioned material can make valve energy resistance to erosion, corrosion-resistant and raising life-span.
Working principle of the present utility model is: rotation hand wheel, makes valve rod do downward vertical motion, drives flashboard downward together with adjustment plate when downward, adjustment plate forces in body base time downward, valve plate can decline along the inclined-plane on adjustment plate, thus reaches complete seal, and sealing force is even.
More than show and describe the utility model major character, principle and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
