Description
Technical field
The utility model relates to valve technology field, especially a kind of spring rock gas safety valve that is installed on natural-gas transfer pipeline.
Background technique
Safety valve shields on the pipeline of interior pressure and container being subject to, and prevents superpressure, ensures safety.When pressure medium in protected system is elevated to while exceeding specified value (being the cracking pressure of safety valve), safety valve is opened automatically, and discharge unit medium prevents that pressure from continuing to raise; In the time that pressure medium is reduced to specified value (being the Reseating pressure of a safety valve of safety valve), automatically close.In natural gas line course of conveying, safety valve has irreplaceable effect.Traditional safety valve structure complexity, install and maintenance comparatively complicated, close not rapidly, and sealability is bad, 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, good sealing effect, opens spring rock gas safety valve rapidly.
The utility model solves the technological scheme that its technical problem adopts: a kind of spring rock gas safety valve, there is valve body, described valve body is provided with suction port and air outlet, described valve body top is disposed with valve gap and safety guard plate, in valve body, be provided with valve rod, valve gap center is provided with leading type connecting rod, and valve gap is provided with upper springs seat and lower springs seat, between upper springs seat and lower springs seat, the spring being set on leading type connecting rod is installed; Described valve rod one end is connected with valve plate, and the valve rod the other end is connected with leading type connecting rod; Described valve body is provided with the seal ring valve seat that forms sealing configuration with valve plate; Between described safety guard plate and valve gap, be provided with sleeve base, sleeve base is provided with the telescopic screw that is set in leading type connecting rod.
Further, described is provided with Gland between valve body and valve gap, and valve rod is connected with leading type connecting rod through stretching into valve gap after Gland, establishes Packed packing layer between described valve rod and Gland.
Further, described suction port is vertical with air outlet arranges.
Further, between described valve body and valve gap, connect by clamping bolt.
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, being provided with spring, valve plate and seal ring valve seat cooperatively interacts, opening and closing is rapid, promote the sealability of spring rock gas safety valve, safety valve manufacture simultaneously and maintenance are all more convenient, long service life.
Brief description of the drawings
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. suction port, 3. valve rod; 4. lower springs seat, 5. spring, 6. upper springs seat; 7. leading type connecting rod, 8. telescopic screw, 9. safety guard plate; 10. sleeve base, 11. air outlets, 12. valve gaps; 13. clamping bolts, 14. Glands, 15. packing layers; 16. seal ring valve seats, 17. valve plates.
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.
Spring rock gas safety valve as shown in Figure 1, there is valve body 1, valve body 1 is provided with suction port 2 and air outlet 11, valve body 1 top is disposed with valve gap 12 and safety guard plate 9, in valve body 1, be provided with valve rod 3, valve gap 12 centers are provided with leading type connecting rod 7, and valve gap 12 is provided with upper springs seat 6 and lower springs seat 4, and the spring 5 being set on leading type connecting rod 7 is installed between upper springs seat 6 and lower springs seat 4; Valve rod 3 one end are connected with valve plate 17, and valve rod 3 the other ends are connected with leading type connecting rod 7; Valve body 1 is provided with the seal ring valve seat 16 that forms sealing configuration with valve plate 17; Between safety guard plate 9 and valve gap 12, be provided with sleeve base 10, sleeve base 10 is provided with the telescopic screw 8 that is set in leading type connecting rod 7.
Between valve body 1 and valve gap 12, be provided with Gland 14, valve rod 3 is connected with leading type connecting rod 7 through stretching into valve gap 12 after Gland 14, establishes Packed packing layer 15 between valve rod 3 and Gland 14; Suction port 2 setting vertical with air outlet 11; Between valve body 1 and valve gap 12, connect by clamping bolt 13; Packing layer 15 is teflon plate filler.
In the time that natural gas line internal pressure is greater than opening pressure of safety valve, rock gas enters from suction port 2, and promotion valve plate 17 moves up and separates with seal ring valve seat 16, and spring rock gas safety valve is opened, air outlet 11 discharge unit rock gases, prevent that pressure from continuing to raise; In the time that natural gas line internal pressure is equal to or less than opening pressure of safety valve, spring 5 discharges torque force, and promotion valve plate 17 moves down with seal ring valve seat 16 and forms sealing configuration, stops natural gas leakage.
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.
