Abstract
The utility model belongs to a stop valve and especially relates to the stop valve with a flange structure. The stop valve comprises a valve body, a valve clack, a valve cover and a hand wheel. A flange is arranged on the valve body and is movably connected with the valve body. The valve clack is arranged on the valve body and is connected with the hand wheel via a valve rod. The valve cover is arranged outside the valve rod. The inside of the valve cover is provided with a winding gasket. A material filling pressing sleeve is also arranged on the valve rod. The valve clack is also connected with a valve seat. The valve rod is connected with the hand wheel via a hexagonal nut. The material filling pressing sleeve is also connected with a material filling pressure plate which is connected with the material filling pressing sleeve via a bolt. Furthermore, the stop valve with the flange structure is simple in structure, high in practicality and low in production cost and is suitable for popularization and application of like products.
Description
Technical field
The utility model belongs to a kind of stop valve, specifically a kind of stop valve with flange arrangement.
Background technique
The open-shut device of stop valve (stop valve, Globe Valve) is the flap of stopper, and sealing surface is plane or the conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, also has lifting rotation rod-type, and stop valve refers to the valve that closure member moves along valve seat center line.According to this mobile form of flap, the variation of valve seat port is and flap stroke relation in direct ratio.Because valve rod unlatching or the shutoff stroke of such valve are relatively short, and there is cutting function very reliably, due to the variation of valve seat port and the stroke of flap relation in direct ratio, be very suitable for the adjusting to flow again.Therefore, such stop valve valve that dams is suitable as cut-out or adjusting and throttling use very much.
But stop valve of the prior art needs larger External Force Acting when opening or closing, and be not suitable for band particle, viscosity is large, the easy medium of coking.Therefore, need technical progress, structural improvement, makes the more convenient use of stop valve.
Model utility content
The purpose of this utility model is in order to solve deficiency of the prior art, and a kind of stop valve with flange arrangement is provided.
The utility model comprises valve body, flap, valve gap, handwheel, wherein flange is arranged on valve body, flange adopts active Placement to be connected with valve body, flap is arranged on valve body, flap is connected with handwheel by valve rod, described valve gap is arranged on the outside of valve rod, and the inner side of valve gap is provided with spirotallic gasket, and filler pressing sleeve is also installed on valve rod.
Valve body of the present utility model is provided with slot, flange is provided with plug, and the plug of flange and the slot of valve body are connected.
Flap of the present utility model is also connected with valve seat.Described valve rod is connected by hexagon nut with handwheel.
On filler pressing sleeve of the present utility model, be also connected with hold-down grid, filler pressing sleeve and hold-down grid are bolted, and described hold-down grid bottom is provided with filler device.
The utility model is the stop valve with flange arrangement, and wherein flange is arranged on valve body, does not need larger external force when opening or closing stop valve.In addition, the utility model is simple in structure, practical, and fabricating cost is not high, and this product is adapted at promoting the use of in like product.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, valve body; 2, flap; 3, valve rod; 4, spirotallic gasket; 5, valve gap; 6, filler pressing sleeve; 7, hold-down grid; 8, handwheel; 9, flange.
Embodiment
For making the technical solution of the utility model and feature clearer, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.At this, following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model comprises valve body 1, flap 2, valve gap 5, handwheel 8, and wherein flange 9 is arranged on valve body 1, and flange 9 plays the effect of fixed valve body 1.Described valve body 1 is provided with slot, flange 9 is provided with plug, and the plug of flange 9 and the slot of valve body 1 are connected, and flange 9 adopts active Placement to be connected with valve body 1, convenient use.
Flap 2 is connected with handwheel 8 by valve rod 3, and described valve rod 3 is connected by hexagon nut with handwheel 8.In concrete use, can drive the flap 2 being connected with valve rod 3 to realize switch, the closure of stop valve by handwheel 8, flange 9 plays the fixedly effect of stop valve, operates more laborsaving.
Flap 2 of the present utility model is also connected with valve seat, on described filler pressing sleeve 6, is connected with hold-down grid 7, and filler pressing sleeve 6 is bolted with hold-down grid 7, and described bolt is the supporting hexagon nut that is connected with also.
Hold-down grid of the present utility model 7 bottoms are provided with filler device.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here cannot give all mode of executions exhaustive.Every still row in protection domain of the present utility model of apparent variation that the technical solution of the utility model extends out or change that belong to.
