Abstract
The utility model discloses a graded flow guide pressure relief valve, which comprises a gas pipeline, wherein the left end and the right end of the gas pipeline are respectively a gas inlet and a gas outlet, a valve cover is arranged in the gas pipeline, a tapered flow guide channel is arranged on the valve cover, the tapered end of the flow guide channel faces the gas inlet, a tapered valve body is arranged on the right side of the flow guide channel, and a rubber pad matched with the valve body and the flow guide channel is arranged between the valve body and the flow guide channel; the right side of the valve body is also provided with a baffle fixed on the inner wall of the gas pipeline, and a spring is arranged between the baffle and the right end face of the valve body. The utility model discloses a mode of hierarchical release gradually reduces the gas pressure in the gas circulation pipeline, guarantees the safety of drilling construction and gas drainage.
Description
Technical field:
This utility model relates to Coal Mining Technology field, particularly relates to a kind of stepped diversion pressure-relief valve.
Background technology:
In the coal seam soft drill of protrusive coal seam of high methane under especially heavily stressed or mash gas extraction process, very easily cause a large amount of gas accumulations in boring, extraction pipeline, transfinite, threaten to the safe efficient production in colliery.
At present, for this type of gas density overrun issues, generally use the gas in pressure-relief valve release gas tube, reduce gas pressure, but existing pressure-relief valve is all thoroughly release in short-term, inevitably cause the unexpected motion of a large amount of gas, it is impossible to eliminate safe hidden trouble completely effectively, very easily equipment and personnel are worked the mischief.
Utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of stepped diversion pressure-relief valve, is gradually lowered the gas pressure in gas tube, it is ensured that the safety of drilling construction and gas pumping.
The technical solution of the utility model is as follows:
Stepped diversion pressure-relief valve, including gas tube, two ends, gas tube left and right respectively gas import and gas export, it is characterized in that, being provided with valve gap in described gas tube, valve gap offers the flow-guiding channel of taper, the tapered end of flow-guiding channel is towards gas import, the right side of flow-guiding channel is provided with the valve body of taper, is provided with the rubber blanket matched between valve body with flow-guiding channel; The baffle plate being fixed on gas tube inwall, spring between baffle plate and valve body right side it is additionally provided with on the right side of described valve body.
Described stepped diversion pressure-relief valve, it is characterised in that described rubber blanket is cone cylinder shape, and rubber blanket is bonded on the flow-guiding channel inwall of valve gap.
Described stepped diversion pressure-relief valve, it is characterised in that described spring is in compressive state, both ends of the spring is individually fixed in valve body with on baffle plate, and spring withstands valve body and contacts with rubber seal.
The utility model has the advantages that:
This utility model adopts the mode of classification release, gradually reduces Gas-Flow and threads a pipe interior gas pressure, it is ensured that the safety of drilling construction and gas pumping.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I I sectional view of this utility model valve gap, valve body, rubber blanket cooperation place.
Detailed description of the invention:
Referring to accompanying drawing:
Stepped diversion pressure-relief valve, including gas tube 1, the respectively gas import 2 of gas tube about 1 two ends and gas export 3, gas tube 1 is provided with valve gap 4, valve gap 4 offers the flow-guiding channel 5 of taper, the tapered end of flow-guiding channel 5 is towards gas import 2, and the right side of flow-guiding channel 5 is provided with the valve body 6 of taper, is provided with the rubber blanket 7 matched between valve body 6 with flow-guiding channel 5; The baffle plate 8 being fixed on gas tube 1 inwall, spring 9 between baffle plate 8 and valve body 6 right side it is additionally provided with on the right side of valve body 6.
Rubber blanket 7 is cone cylinder shape, and rubber blanket 7 is bonded on flow-guiding channel 5 inwall of valve gap 4.
Spring 9 is in compressive state, and spring 9 two ends are individually fixed in valve body 6 with on baffle plate 8, and spring 9 withstands valve body 6 and contacts with rubber blanket 7 sealing.
Spring 9 stiffness factor is different, and the threshold value of pressure-relief valve has tetra-grades of 0.1MPa, 0.3MPa, 0.5MPa, 0.7MPa.
Work process of the present utility model:
Gas flows in gas import 2, when the motive force that valve body 6 is produced by gas pressure is more than the active force of spring 9, valve body 6 will move, and departs from rubber blanket 7, produces gap, gas flows to gas export 3, after gas is discharged, in gas import 2, gas pressure will decline, when the motive force that valve body 6 is produced by gas pressure is less than the active force of spring 9, valve body 6 shifts near rubber blanket 7, continues isolation gas import 2 and gas export 3.
When gas pressure is bigger in gas tube 1, the Gas Flow in pipeline can be regulated by installing the bigger pressure-relief valve of threshold value, release gradually, it is prevented that a large amount of gas move suddenly and equipment and personnel are damaged, safe extraction and construction.
