Abstract
The utility model discloses a gate plate throttling valve playing the function of flow adjustment used for a slurry conveying pipeline. The utility model has the advantages of tight closing, abrasion resistance, corrosion resistance, etc. The public-known gate plate throttling valve mainly comprises a valve cover, a valve body, a valve plate and the elevating mechanism of the valve plate. The utility model is characterized in that the lower end of the valve plate (2) forms a circular arc shape. The radius of the circular arc is consistent with the radius of a flow path (19). The inner surface of the flow path (19) contacted with the lower end of the valve plate (2) is a continuous cylindrical surface.
Description
The utility model relates to a kind of flashboard type throttling valve, has particularly used the throttle valve of regulating action about slurry transportation pipeline.It can be used with stop valves such as ball valves.
At present, the flashboard type throttling valve that known slurry transportation pipeline is used mainly is made up of valve gap, valve body, valve plate, valve plate elevator mechanism, and the surface of contact of valve plate lower end and runner is provided with groove.The problem and shortage part that its exists is, runner trench is easily piled up impurity, causes valve plate to be not closed completely, and the valve plate lower end does not serve as a contrast wear-resisting overcoat, and valve plate is easy to wear, perishable, and working life is short; Do not serve as a contrast anti-wearing liner in the runner, runner is easy to wear, perishable, reduction of service life etc.
The purpose of this utility model is to avoid deficiency in the above-mentioned prior art and a kind of tight, wear-resisting, corrosion resistant new-type slurry transportation pipeline flashboard type throttling valve of cutting out is provided.
The purpose of this utility model can reach by following measure: known slurry is carried and is used the flashboard type throttling valve, mainly is made up of valve gap, valve body, valve plate, valve plate elevator mechanism.Its improvements are that valve plate (2) lower end is circular arc, and the radius of this circular arc is consistent with the radius of runner (19), with the internal surface of the contacted runner in valve plate (2) lower end (19) be the continuous cylinder face.
The purpose of this utility model can also reach by following measure: valve plate (2) lower end can the wear-resisting overcoat of outer lining (18).
The purpose of this utility model can also reach by following measure: wear-resisting overcoat (18) can grind overcoat for resistant polyurethane.
The purpose of this utility model can also reach by following measure: the interior diabase lining cover of runner (19) (3).
The purpose of this utility model can also reach by following measure: interior diabase lining cover (3) is the glass-ceramic basalt lining.
Compared with the prior art the utility model has following advantage and actual effect: because the internal surface of runner (19) is the continuous cylinder surface, do not have groove, therefore be difficult for piling up impurity, be not closed completely; Owing to the wear-resisting overcoat of valve plate lower end outer lining, diabase lining in the runner is so therefore wear resistant corrosion resistant, has improved 3-5 working life doubly again.
The accompanying drawing drawing is described as follows:
Fig. 1, structure of the present utility model is not intended to
Fig. 2, the valve plate plan view
Fig. 3, the A-A sectional view
1, valve body 2, valve plate 3, cast stone lining 4, rubber cushion 5, two way sealed circle 6, connecting body 7, valve gap 8, packing 9, end cap 10, bearing 11, fastening screw trip bolt 12, handwheel 13, back-up ring 14, copper nut 15, screw mandrel 16, plug 17, machinery oil 18, wear-resisting overcoat 19, runner
The utility model embodiment in conjunction with the accompanying drawings is described in further detail: valve plate (2) lower end semicircular in shape, this radius of a circle equal the radius of runner (19); The wear-resisting overcoat of polyurethane, thickness 5 millimeter, semicircular in shape are gluedd joint in valve plate (2) lower end; Runner (19) is the continuous cylinder face with valve plate (2) lower end surface of contact, and both runner (19) internal surface did not have groove; Runner (19) liner glass-ceramic basalt, cast stone thickness is 15～20 millimeters.All the other are known technology, so seldom narration.
Claims (5)
1, a kind of slurry transportation pipeline flashboard type throttling valve, mainly form by valve gap, valve body, valve plate, valve plate elevator mechanism, it is characterized in that: valve plate (2) lower end is circular arc, the radius of this circular arc is consistent with the radius of runner (19), with the internal surface of the contacted runner in valve plate (2) lower end (19) be the continuous cylinder surface.
2, throttle valve according to claim 1 is characterized in that said valve plate (2) the wear-resisting overcoat of lower end outer lining (18).
