Abstract
The utility model discloses a stop valve with a simple structure, convenience in assembly, low material and assembly costs, easiness in dismounting and maintenance, and more reasonability in resource utilization. The stop valve comprises a valve body, a valve rod, a valve cap, a valve clack, a pressure cap and a handwheel, wherein an inlet, an outlet and a valve port, through which a medium flows, are formed on the valve body; the upper part of the valve body is in sealed connection with the lower part of the valve cap; the valve clack is mounted at the lower end of the valve rod and is arranged in the valve cavity of the valve body in a position corresponding to the valve port; the upper end of the valve rod penetrates through the valve cap and the pressure cap, and is connected with the handwheel; packing is arranged between the inner wall at the upper part of the valve cap and the valve rod; the upper part of the valve cap is in sealed connection with the pressure cap; and a gasket is arranged between the pressure cap and the packing.
Description
Technical field
The utility model relates to a kind of valve, relates in particular to a kind of stop valve.
Background technique
Stop valve also is pipe valve, is installed on the circulation that is used for the pilot line medium in the pipeline or ends.Its structure of existing stop valve is as shown in Figure 1; Comprise valve body 1 ', valve rod 2 ', flap 3 ', upper bracket 4 ', lower support frame 5 ', Stem Mut 6 ', handwheel 7 ', Gland 8 ', filler 9 ' and Packing seat 10 '; Said valve body 1 ' is provided with the passage 11 ' that connects its valve pocket; The lower end that flap 2 ' is loaded on valve rod 1 ' places in the valve pocket, and corresponding with passage 11 ', and filler 9 ' and Packing seat 10 ' are located between valve body 1 ' cavity inner wall and the valve rod 2 '.The outer surface of upper of valve body 1 ' is through ending a screw 12 ' and splitting annulus 13 ' and be connected with lower support frame 5 '; Upper bracket 4 ' bottom is threaded together with lower support frame 5 ' top, and the top of valve body 1 ' is connected with Gland 8 ' through straight pin 14 ', bolt 15 ' and nut 16 '.The cavity that Gland 8 ' places upper bracket 4 ' is passed in valve rod 2 ' upper end; The boss of the lower end of handwheel 7 ' is loaded in the groove on Stem Mut 6 ' top; Stem Mut 6 ' places upper bracket 4 ' top inner chamber; Between Stem Mut 6 ' and the upper bracket 4 ' inwall, be provided with bearing 17 ' between the outside of upper bracket 4 ' inwall and valve rod 2 '; Upper bracket 4 ' the top bearing gland 18 ' that has been threaded, Stem Mut 6 ' inner chamber is threaded with valve rod 2 ' upper end, between the inwall of the valve rod 2 ' outside and upper bracket 4 ', is being provided with flat key 19 '.
Though the stop valve of said structure can reach the circulation of effective pilot line medium or end, the number of fitting parts of its entire product is many, reliability decrease.Simultaneously, because accessory is many, corresponding cost of material, purchase cost, assembly cost and administration expenses are also many, cause the Economy of entire product to descend; Because more, the structure more complicated of accessory of this stop valve, when stop valve had damage slightly, the dismounting maintenance is trouble very in addition, generally can only integral replacing, and the waste resource.
Summary of the invention
To the problem of above-mentioned existence, a kind of simple in structure, easy to assembly, material is provided the utility model and assembly cost is low, the dismounting maintenance easily, the stop valve of making rational use of resources more.
For solving this technical problem, the utility model is taked following scheme: stop valve comprises valve body, valve rod, valve gap, flap, pressure cap and handwheel; Said valve body is provided with import, outlet and the valve port of medium circulation, and valve body top and bonnet lower are tightly connected, and flap is loaded on the valve rod lower end and places in the valve body valve pocket; And it is corresponding with valve port; Valve gap and pressure cap are passed in the valve rod upper end, and are connected with handwheel, are provided with filler between valve gap upper inside wall and the valve rod; Valve gap top and pressure cap are tightly connected, and are provided with a packing ring between pressure cap and the filler.
Further, the junction plane of said valve body and valve gap is provided with pad.
Preferably, said handwheel is anchored on the valve rod upper end through hexagon nut.
Through adopting the aforementioned techniques scheme, the beneficial effect of the utility model is: the stop valve accessory of the utility model is less, assemble simple and conveniently, has reduced working strength of workers, and the while also greatly reduces cost of production, for enterprise obtains more profit; In addition, the utility model simple in structure dismantled convenience easy to maintenance, when stop valve has damage slightly, do not need integral replacing, can take maintenance easily apart.
Description of drawings
Fig. 1 is the structural representation of existing stop valve;
Fig. 2 the utility model embodiment's structural representation.
Embodiment
Combine accompanying drawing and specific embodiment that the utility model is further specified at present.
With reference to figure 2; The utility model embodiment discloses a kind of stop valve; Comprise valve body 1, flap 2, valve rod 3, valve gap 5, pressure cap 8 and handwheel 9, said valve body 1 is provided with import, outlet and the valve port of medium circulation, and valve body 1 top is connected with valve gap 5 lower thread; And the junction plane of valve body 1 top and valve gap 5 bottoms is provided with pad 4, makes both better tightness.Flap 2 is loaded on valve rod 3 lower ends and places in valve body 1 valve pocket, and corresponding with valve port, and valve gap 5 and pressure cap 8 are passed in valve rod 3 upper ends; And be fixedly connected with handwheel 9 through hexagon nut 11; Be provided with a label 10 on the handwheel 9 and between the hexagon nut 11, valve rod 3 is threaded with valve gap 5, makes valve rod 3 to make rotary lifting movement along valve gap 5; The flap 2 that drives valve rod 3 lower ends is simultaneously done elevating movement, is used to open and close valve body 1 valve port.Be provided with filler 6 between valve gap 5 upper inside wall and the valve rod 3, valve gap 5 tops are threaded with pressure cap 8, are provided with a packing ring 7 between pressure cap 8 and the filler 6, make packing ring 7 compressible fillers 6 reach sealing purpose through the pressure cap 8 of screwing.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; Concrete this technological scheme method of realization and approach are a lot; The above only is the preferred implementation of the utility model, but the those skilled in the art should be understood that in the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
