Description
Technical field
The utility model relates to valve technology field, especially a kind of rock gas Lift check valve being installed on natural gas line conveying.
Background technique
Be used for controlling the flow of gas or liquid in pipeline, reduce their pressure or change the parts of flow direction, being commonly referred to as valve.In natural gas line conveying, indispensable valve is safety check, is most popular a kind of valve.Safety check is again check valve or one-way valve.It relies on the automatic open and close flap of flowing of medium itself, is used for preventing air-flow in pipeline from flowing backwards.When producing refluence, flap will be closed automatically.Safety check is generally used on the outlet conduit of natural gas compressor, shutdown or when having a power failure suddenly, prevent the pressurized gas in pipe from flowing backwards, this refluence often causes compressor high speed reverse rotation, formation mechanical accident.Traditional check valve structure is complicated, be not easy to processing, Operation and Maintenance is inconvenient, and due to the friction that valve plate is closed, easily cause the wearing and tearing of seal ring, 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, provides a kind of structure simple, crashproof anti abrasive rock gas Lift check valve.
The utility model solves the technological scheme that its technical problem adopts: a kind of rock gas Lift check valve, has valve body and valve gap, is provided with valve seat in described valve body, and the channel partition in valve body is become air inlet section and air outlet section by valve seat; Described valve gap inwall central vertical is provided with flange collar, and flange collar is built-in with spring pedestal, and spring pedestal is fixed with spring; Described valve body is built-in with valve rod, and valve stem end is connected with valve plate, and spring housing is located at outside valve rod; Described valve plate is being provided with crashproof raised line near valve seat side.
Further, the import of described air inlet section and the outlet of air outlet section is all one-body molded flange.
Further, seal ring is provided with between described valve body and valve gap.
Further, be fixedly connected with by clamping bolt between described valve body and valve gap.
Further, described crashproof raised line is rubber flange collar.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, switch is rapid, is installed on horizontal pipe, valve plate is perpendicular to the passage of valve body, move along valve seat center line, valve plate is opened by the thrust of air-flow, falls by gravity and spring torsion, be provided with crashproof raised line, crashworthiness is good, manufactures 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, 2. valve gap, 3. flange collar, 4. spring pedestal, 5. spring, 6. seal ring, 7. clamping bolt, 8. air inlet section, 9. air outlet section, 10. valve rod in figure, 11. valve plates, 12. valve seats, 13. crashproof raised lines.
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, and therefore it only shows the formation relevant with the utility model.
Rock gas Lift check valve as shown in Figure 1, has valve body 1 and valve gap 2, is provided with valve seat 12 in valve body 1, and the channel partition in valve body 1 is become air inlet section 8 and air outlet section 9 by valve seat 12; Valve gap 2 inwall central vertical is provided with flange collar 3, and flange collar 3 is built-in with spring pedestal 4, and spring pedestal 4 is fixed with spring 5; Valve body 1 is built-in with valve rod 10, and valve rod 10 end is connected with valve plate 11, and spring 5 is set in outside valve rod 10; Valve plate 11 is being provided with crashproof raised line 13 near valve seat 12 side.
The import of the air inlet section 8 and outlet of air outlet section 9 is all one-body molded flange; Seal ring 6 is provided with between valve body 1 and valve gap 2; Be fixedly connected with by clamping bolt 7 between valve body 1 and valve gap 2; Crashproof raised line 13 is rubber flange collar.
During normal work, rock gas enters from air inlet section 8, upwards opens at Imported gas forced under pressure valve plate 11, enters air outlet section 9 and circulates; When shutdown or when having a power failure suddenly, valve plate 11 will automatically be closed under the effect of gravity and spring torsion, prevent the pressurized gas in pipe from flowing backwards.
Above-mentioned mode of execution is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
