At present, for this type of gas density overrun issues, gas in usual utilization pressure-relief valve release gas tube, reduce gas pressure, but existing pressure-relief valve is all thoroughly releases in short-term, inevitably cause the unexpected motion of a large amount of gas, can not eliminate safe hidden trouble completely effectively, very easily equipment and personnel are worked the mischief.
summary of the invention:
In order to make up prior art problem, the object of this invention is to provide a kind of stepped diversion pressure-relief valve and installation and application thereof, reducing the gas pressure in gas tube gradually, ensureing the safety of drilling construction and gas pumping.
Technological scheme of the present invention is as follows:
Stepped diversion pressure-relief valve, comprise gas tube, two ends, gas tube left and right are respectively gas import and gas export, it is characterized in that, be provided with valve gap in described gas tube, valve gap offer the guide channel of taper, the cone end of guide channel is towards gas import, the right side of guide channel is provided with the valve body of taper, is provided with the rubber pad matched between valve body with guide channel; The baffle plate be fixed on gas tube inwall is also provided with, spring between baffle plate and valve body right side on the right side of described valve body.
Described stepped diversion pressure-relief valve, is characterized in that, described rubber pad is cone barrel type shape, and rubber pad is bonded on the guide channel inwall of valve gap.
Described stepped diversion pressure-relief valve, it is characterized in that, described spring is in compressive state, both ends of the spring is individually fixed on valve body and baffle plate, and spring withstands valve body and contacts with rubber seal.
The installation and application of stepped diversion pressure-relief valve, is characterized in that, comprises the steps:
1) valve gap, valve body, baffle plate, rubber pad, the spring that are used in combination with gas tube, is processed;
1), in valve gap guide channel adhesive rubber pad, then at the interval, middle part of gas tube, valve gap, baffle plate are installed;
2), at baffle plate and valve gap opposing side be provided with spring, spring at front end is fixed on the valve body that valve gap matches;
3), the medial axis height of valve body and spring, valve gap guide channel height be identical and coaxial with gas tube, withstands on rubber pad by valve body front end;
4), gas tube import connects gas source, and gas tube outlet is led to and connected discharge conduit or collection conduit.
Advantage of the present invention is:
The present invention adopts the mode of classification release, progressively reduces Gas-Flow and to thread a pipe interior gas pressure, ensure the safety of drilling construction and gas pumping.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention.
Fig. 2 is I-I sectional view of valve gap of the present invention, valve body, rubber pad cooperation place.
embodiment:
See accompanying drawing:
Stepped diversion pressure-relief valve, comprise gas tube 1, gas tube about 1 two ends are respectively gas import 2 and gas export 3, valve gap 4 is installed in gas tube 1, valve gap 4 offers the guide channel 5 of taper, the cone end of guide channel 5 is towards gas import 2, and the right side of guide channel 5 is provided with the valve body 6 of taper, is provided with the rubber pad 7 matched between valve body 6 with guide channel 5; The baffle plate 8 be fixed on gas tube 1 inwall is also provided with, spring 9 between baffle plate 8 and valve body 6 right side on the right side of valve body 6.
Rubber pad 7 is cone barrel type shape, and rubber pad 7 is bonded on guide 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 seals with rubber pad 7 and contact.
Spring 9 [coefficient of is different, and the threshold value of pressure-relief valve has 0.1MPa, 0.3MPa, 0.5MPa, 0.7MPa tetra-grades.
The installation and application of stepped diversion pressure-relief valve, comprises the steps:
1) valve gap 4, valve body 6, baffle plate 8, rubber pad 7, the spring 9 that are used in combination with gas tube 1, is processed;
1), in valve gap 4 guide channel adhesive rubber pad 7, then at the interval, middle part of gas tube 1, valve gap 4, baffle plate 8 are installed;
2), at baffle plate 8 and valve gap 4 opposing side be provided with spring 9, the valve body 6 that valve gap matches is fixed in spring 9 front end;
3), the medial axis height of valve body 6 and spring 9, valve gap 4 guide channel height be identical and coaxial with gas tube 1, withstands on rubber pad 7 by valve body 6 front end;
4), gas tube 1 import connects gas source, and gas tube 1 outlet is led to and connected discharge conduit or collection conduit.
Working procedure of the present invention:
Gas flows in gas import 2, when gas pressure is greater than the active force of spring 9 to the Driving force that valve body 6 produces, valve body 6 will move, and departs from rubber pad 7, produces gap, Gas-Flow is to gas export 3, after gas is discharged, in gas import 2, gas pressure will decline, when gas pressure is less than the active force of spring 9 to the Driving force that valve body 6 produces, valve body 6 shifts near rubber pad 7, continues isolation gas import 2 and gas export 3.
When gas pressure is larger in gas tube 1, regulating Gas Flow in pipeline, release gradually by installing the larger pressure-relief valve of threshold value, preventing a large amount of gas from moving suddenly and equipment and personnel damaged, safe extraction and construction.
