Abstract
The utility model discloses an abrasion-reducing device for a valve. The upper half part is a tubular body (6), and a lower half part is a cone body (4); the upper half part is connected with the lower half part through flanges (5, 5). The inside of the horn mouth of the cone body (4) is placed with a damping plug (3) dovetailed with the horn mouth, and the top of the tubular body (6) of the upper half part is sealed. The side face thereof is provided with holes. The utility model has the advantages of simple structure, reliable working, low cost, no maintenance, etc. and can obviously reduce the abrasion of the valve. The utility model can be used for pipeline transportation of materials in metallurgy industry, the coloring metal industry, the coal industry, the chemical industry, the building material industry, the cement industry, etc.
Description
The utility model relates to a kind of material that is used for and falls wear device at the valve of pipe conveying procedure, it can reduce valve opening effectively or when closing material can in the line transportation of industries such as metallurgical, coloured, coal and chemical industry, building materials, cement, use the wearing and tearing of valve.
In the pipe conveying procedure of material, material can produce wear phenomenon, particularly valve opening in various degree or the moment of closing to all kinds of valves, and valve is young, flow velocity is big, and material is the most serious to impact, the wearing and tearing of valve.For example, in the ore dressing plant flotation lime milk add-on system because lime fires raw material quality and technology instability, in the finished product lime with broken impurity of difficulty hard to tolerate such as a large amount of cinder bits, stones.After lime was made lime milk, such impurity was respectively added a little to flotation through line transportation by sand pump in company with lime milk.Impure lime milk is to conveying equipment, and all kinds of valves of particularly exchanging joint lime milk consumption produce very big wearing and tearing, thereby greatly reduced the working life of valve, and maintenance increases, and cost of production increases.Therefore, reduce the wearing and tearing of valve, be very necessary the working life of improving valve.At present, the main way that is used for reducing the valve wearing and tearing has: reduce discharge pressure, lower material flow; Adopt high-abrasive material to improve the antiwear property of valve; Select for use extraordinary valve to resistance to wear etc., but there is following problems in actual applications in these class methods: to reduce flow velocity and may cause a deficiency of adding the some amount, also can cause pipeline scale to stop up; Adopt the abrasion-resistance of high-abrasive material raising valve or select extraordinary valve for use, though certain effect is arranged, far can not satisfy industrial requirement its working life.And up to the present, the research for the working life of improving valve is limited to the research of resistance to wearing to valve itself substantially, yet there are no the research that is used to reduce the device that valve weares and teares and reports.
The purpose of this utility model is exactly at the above-mentioned problems in the prior art, provides a kind of simple in structure, with low cost, use reliable, can significantly reduce valve opening or when closing material wear device is fallen in the impact of valve and the valve of wearing and tearing.
For achieving the above object, the utility model by the following technical solutions:
Wear device falls in the utility model valve, and to be designed to the first half be tubular body, and Lower Half is a cone, and the two joins by flange.In the loudspeaker mouth of cone, lay the damping plug that matches with cone.The top seal of first half tubular body, its side is provided with perforate.
The best when above-mentioned damping plug is bulb stopper or round platform plug can guarantee to cooperate with the effective of cone.
Be the perforate of avoiding damping plug when come-up to stop up the tubular body side, this perforate can be arranged on the place, dead angle of tubular body top-side.
We know under the certain situation of pressure, during valve closing mouth from large to small, material flow changes from small to big; During valve opening, although mouthful change from small to big, flow velocity from large to small, the valve in the opening process hole when opening the normal operation in back all the time is little, promptly the flow velocity in the opening process is big.Because it is material flow is big more, big more with wearing and tearing to the impact of valve; Material flow is more little, and is corresponding more little with wearing and tearing to the impact of valve.Therefore, we can say in the moment of valve closing and unlatching wearing and tearing maximum.The utility model valve falls among the pipeline that wear device is installed in valve links to each other, it just in time is the moment of utilizing valve closing and unlatching, flow is little and can't wash the wear-resistant damping bulb stopper (or round platform plug) with certain weight proportion open, thereby suppresses valve closing effectively and open the wearing and tearing of moment.By the time during valve wide open, flow becomes washes damping bulb stopper (or round platform plug) greatly open, and the wearing and tearing of damping bulb stopper (or round platform plug) are corresponding less, can protect damping bulb stopper (or round platform plug) effectively.In addition, when flow is varied down to can not wash damping bulb stopper (or round platform plug) open the time by valve regulated, damping bulb stopper (or round platform plug) can fall into taper mouth automatically under the effect of gravity, mouth is sealed up.Utilize above-mentioned know-why, the antiwear property that wear device can improve valve widely falls in valve, protects valve effectively, and device carries out automatically, and reliability and working life are longer.
For describing the utility model better, below in conjunction with drawings and Examples wear device is fallen in the utility model valve and be described in further detail.
Fig. 1 falls the wear device structural representation for the utility model valve.
The damping round platform that Fig. 2 adopts for the utility model is the shape schematic representation beyond the Great Wall.
Fall in the wear device structural representation at valve shown in Figure 1, upper tubular body 6 is designed to cylindrical tube, and cylindrical tube 6 side top perforates are connected with flanged (FLGD) pipe 7; Lower Half is a cone 4, in the cone 4 loudspeaker mouths ball plug 3 is housed, and cone 4 loudspeaker mouths are connected with straight tube 2, and flange 1 is equipped with in the lower end of straight tube 2.Tubular body 6 and cone 4 be by flange 5,5 ' be connected, flange 5,5 ' between add rubber seal by bolt tightening.
Shown in Figure 2 is damping round platform that the utility model adopts is the shape schematic representation beyond the Great Wall.The round platform plug is loaded in the cone 4 loudspeaker mouths, and shape and cone are complementary.
The said structure integral material selects for use A3 steel or glass fibre reinforced plastics to make.The cone shape loudspeaker mouth 4 that adopts the A3 steel to do can be selected the abrasive rubber lining for use.Damping bulb stopper optional abrasive rubber of (or round platform plug) 3 materials or stainless steel.
By the logistics direction, when installing before the valve, valve is connected with flanged (FLGD) pipe 7; When installing behind the valve, valve is connected with flange 1.
The utility model compared with prior art has following good effect:
1. can effectively suppress valve closing and unlatching moment material to the wearing and tearing of valve, greatly Improve the service life of valve, save the valve maintenance cost.
2. overall structure is simple, and effect is remarkable, is easy to make, and is with low cost.
3. the single unit system anti-adverse environment is non-maintaining, and the life-span is long.
Literature search is the result show: up to the present, also do not have to find and the utlity model has phase Same purpose, the product of same or similar structure.
