Abstract
The utility model discloses a combined mining slurry valve. A valve body is formed by the connection of two sealing plates, and a gate valve chamber is arranged between the two sealing plates. The plate surface of each sealing plate and a gate valve are provided with flow guiding holes. The gate valve is in splicing match with the gate valve chamber between the sealing plates. Because the valve body adopts a combined structure, the utility model has the advantages of simple structure and convenient maintenance. Because the gate valve is pulled and moved upward when the valve is closed, and flow guiding holes on the valve body are closed by the plate surface on the lower end of the gate valve, and therefore, solid particles in ore slurry can not be piled up and can not block the gate valve. Therefore, the valve body can be reliably closed. The utility model avoids the valve parts from being eroded by high-speed flow and has long service life. The combined mining slurry valve is a novel and unique valve kind product.
Description
The utility model relates to a kind of valve, more particularly relates to a kind of combined type ore pulp valve, belongs to a kind of improvement of gate valve.
At present, contain on the pipeline of solid particle ore pulp, adopt the little gate valve of fluid resistance to block or connect the ore pulp MEDIA FLOW usually remote the conveying.This gate valve structure complexity, maintenance trouble, when connecting the ore pulp MEDIA FLOW, to be enclosed in flashboard on the valve body pod apertures earlier and upwards lift mobilely by control gear, and make whole flashboard upwards shift out the valve body pod apertures, at this moment the ore pulp MEDIA FLOW just can be through pod apertures proper flow in pipe of valve body; But when will moving down the flashboard throttle down when blocking the ore pulp MEDIA FLOW, the solid particle in the ore pulp MEDIA FLOW tends to be deposited in the bottom of pod apertures and blocks flashboard, makes the bottom that flashboard can't fall back to pod apertures normally that valve is thoroughly closed.Like this, just formed a high speed flow in the bottom of valve body pod apertures, valve body has quickened the quick wearing and tearing of valve member under the erosion that contains the solid particle medium high speed flow, caused valve body working life the longlyest to be less than two months, increased the maintenance expenses of mining equiment greatly, strengthened the operating cost in mine, produced to the mine and brought inconvenience.
The purpose of this utility model provides a kind of combined type ore pulp valve, it is not only simple in structure, easy to maintenance, and the solid particle in the ore pulp can't be deposited in the bottom of valve body pod apertures, and valve body can reliably be closed up hill and dale, eliminated the erosion of high speed flow, the valve body long service life to valve member.
The purpose of this utility model is to realize like this, it includes valve body, flashboard, it is characterized in that valve body is fastened and connected by two sealing plates, between two sealing plates, be provided with the flashboard chamber, sealing plate have pod apertures on the plate face, be provided with pod apertures on flashboard equally, flashboard is pegged graft with the flashboard chamber between the sealing plate and is cooperated.
Owing to adopted such scheme, valve body is fastened and connected into fabricated structure with two sealing plates, so it is simple in structure, keep in repair very convenient, during again owing to throttle down is upwards to lift flashboard, pod apertures on the flashboard upwards shifts out the pod apertures on the sealing plate, by the plate face of flashboard lower end the pod apertures on the sealing plate is closed at last, therefore the solid particle in the ore pulp can't be piled up and get off to block flashboard, so just can easily valve body reliably be closed up hill and dale, avoided in valve body, producing high speed flow to the valve member erosion, make the life-span of ore pulp valve extend available more than 5 years greatly, maintenance expenses and mine operation cost have been reduced significantly, have simple in structure, long service life, characteristics easy to maintenance are a kind of novelty and the valve series products that shows unique characteristics.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a partly generalized section of concrete structure of the present utility model.
Fig. 2 is the sealing plate tectonic maps of valve body.
In Fig. 1-2, a kind of combined type ore pulp valve, it includes valve body, flashboard 13, and valve body is made with the sealing plate 5 of two symmetries.Sealing plate 5 is the rectangular steel plate, and the recessed ladder mouth 14 of symmetry is arranged on two stiles of sealing plate 5 inboards, also has pod apertures 7 on the plate face of sealing plate 5 bottoms.One of welding is used for and pipeline flange connecting dish 6 on the sealing plate 5 in pod apertures 7 outsides.Two 5 of sealing plates also insert and put and are fixed with positive stop strip 4, being folded in respectively on two sealing plates, the 5 inboard recessed ladder mouths 14 of its steel with isometric two positive stop strips 4 of sealing plate 5, and sealing plate 5 is tightened to one by screw with bolt 9 with positive stop strip 4.The sealing plate 5 of valve body surrounds a flashboard chamber that communicates up and down with 4 of positive stop strips.Side inner panel face at sealing plate 5 has annular seal groove around pod apertures 7, and the cross section of O-ring seal 15 takes the shape of the letter U, and its U-shaped opening is towards the circle heart.O-ring seal 15 places in the annular seal groove on the sealing plate 5 side inner panel faces.Having a pod apertures 8 on the upper head plate face of flashboard 13 equally, pegs graft and cooperates in the flashboard chamber that flashboard 13 becomes with two sealing plate 5 therebetween of valve body.Limiting board 10 usefulness screws 11 are fixed on flashboard 13 bottom end faces, on the top of flashboard 13 caging bolt 3 are housed also.Transmission device be a kind of with leading screw 2 manually remove wheel 1, transmission device is screwed on the otic placode 12 of sealing plate 5 upper ends welding by support, the leading screw 2 on the transmission device is screwed with flashboard 13 upper ends and is connected.
At work, in the time will opening valve connection ore pulp MEDIA FLOW, clockwise rotate handwheel 1, driving the flashboard 13 that is enclosed on the valve body pod apertures 7 by the leading screw 2 that is connected with handwheel 1 moves down, the pod apertures 8 of flashboard 13 upper head plate faces is overlapped to the pod apertures 7 that is displaced downwardly to on the valve seal plate 5, and at this moment the ore pulp MEDIA FLOW just can be through pod apertures 7 proper flow in pipeline of valve body; When wanting throttle down to block the ore pulp MEDIA FLOW, rotate counterclockwise handwheel 1, driving flashboard 13 by the leading screw 2 that is connected with handwheel 1 moves up, make the pod apertures 8 of flashboard 13 upper head plate faces upwards shift out valve body pod apertures 7, block ducted ore pulp MEDIA FLOW by the pod apertures 7 on the plate face valve body of flashboard 13 bottoms.Because flashboard 13 moves up during throttle down, so the bottom that the solid particle in the ore pulp MEDIA FLOW can't be deposited in pod apertures 7 blocks flashboard 13, and flashboard 13 can thoroughly cut out the pod apertures 7 of valve body easily.
