Description

Direct current type rock gas stop valve
Technical field
The utility model relates to valve technology field, especially a kind of direct current type rock gas stop valve that is installed on natural gas line conveying.
Background technique
In pipeline, be used for controlling the flow of gas or liquid, reduce their pressure or the parts of change flow direction, be commonly referred to as valve.In natural gas line conveying, indispensable valve is stop valve, is most popular a kind of valve.The closed principle of stop valve is that dependence valve thick stick pressure, fits tightly valve clack sealing surface and sealing surface of seat, stops medium circulation.Traditional stop valve structure is complicated, be not easy to processing, Operation and Maintenance is inconvenient, due to the friction of valve plate closure, easily causes the wearing and tearing of seal ring, and working life is short, and sealability declines, and easily reveals.
Model utility content
The technical problems to be solved in the utility model is: overcome the deficiency in prior art, provide a kind of simple in structure, the direct current type rock gas stop valve of good sealing effect.
The utility model solves the technological scheme that its technical problem adopts: a kind of direct current type rock gas stop valve, have valve body, valve body top is provided with filler base, and filler base upper end is connected with Gland, Gland top is provided with valve gap, and valve gap top is provided with gear-box; Described gear-box is built-in with gear; In described valve body, be provided with valve rod, valve rod one end is connected with valve plate, and the valve rod the other end is successively through being threaded with handwheel after filler base, Gland, valve gap and gear-box; Described valve rod is arranged with packing layer with the position that filler base contacts.
Further, be provided with feed cavity and discharging chamber in described valve body, discharging chamber is positioned at feed cavity top, and described valve plate is positioned at discharging chamber.Comparatively laborsaving when Open valve like this.
Further, between described filler base and Gland, pass through the fastening installation of stud bolt.
Further, described valve rod is arranged with axle sleeve at the position that contacts with valve gap and gear-box.
Further, described packing layer is teflon plate filler.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, and handwheel rotarily opens or cut out stop valve, flexible movements, and switch is rapid; Filler base, Gland and packing layer cooperatively interact, and have improved the sealability of stop valve, manufacture simultaneously and overhaul all more convenient, long service life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. valve bodies in figure, 2. feed cavity, 3. discharging chamber, 4. filler base, 5. Gland, 6. valve gap, 7. gear-box, 8. gear, 9. valve rod, 10. valve plate, 11. packing layers, 12. stud bolts, 13. handwheels, 14. axle sleeves.
Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
Direct current type rock gas stop valve as shown in Figure 1, has valve body 1, and valve body 1 top is provided with filler base 4, and filler base 4 upper ends are connected with Gland 5, and Gland 5 tops are provided with valve gap 6, and valve gap 6 tops are provided with gear-box 7; Gear-box 7 is built-in with gear 8; In valve body 1, be provided with valve rod 10, valve rod 10 one end are connected with valve plate 10, and valve rod 10 the other ends are successively through being threaded with handwheel 13 after filler base 4, Gland 5, valve gap 6 and gear-box 7; The position that valve rod 10 contacts with filler base 4 is arranged with packing layer 11.
In valve body 1, be provided with feed cavity 2 and discharging chamber 3, discharging chamber 3 is positioned at feed cavity 2 tops, and valve plate 10 is positioned at discharging chamber 3; Between filler base 4 and Gland 5, pass through the fastening installation of stud bolt 12; Valve rod 10 is arranged with axle sleeve 14 at the position that contacts with valve gap 6 and gear-box 7; Packing layer 11 is teflon plate filler.
When stop valve is opened, rock gas circulates through discharging chamber 3 from feed cavity 2; While closing stop valve, handwheel 13 rotations, the gear 8 in driving gearbox 7 rotates, thus band ovable valve stem 9 rotates, and valve plate 10 is closed downwards, the circulation of blocking-up rock gas.
Above-mentioned mode of execution is only explanation technical conceive of the present utility model and feature; its object is to allow person skilled in the art can understand content of the present utility model and be implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
