Abstract
The utility model provides a BOP control emergency gas source control device, comprising a gas source, an emergency control device and a BOP control device, wherein the gas source supplies gas to the BOP control device through the emergency control device, the emergency control device comprises a check valve, a two-position three-way pneumatic operated directional valve, an emergency gas pocket and a gas horn, the air source is connected with the emergency gas pocket through the check valve, and is also connected with the two-position three-way pneumatic operated directional valve, the emergency gas pocket is connected with the two-position three-way pneumatic operated directional valve, the two-position three-way pneumatic operated directional valve is connected with the gas horn, and the gas horn is connected with the BOP control device through the check valve. The BOP control emergency gas source control device has the beneficial effects that the emergency gas pocket is not used for supplying gas to the outside, the main gas of the gas source is directly supplied to the BOP control device; when a main gas circuit of the gas source is lack of gas, the emergency gas pocket works for supplying gas to the BOP control device, the gas horn gives the alarm, and the normal work of the BOP control device is ensured while the circuit is timely overhauled, so that the operation is more convenient; the BOP control emergency gas source control device has the advantages of simple structure, convenience in maintenance, ensuring the safety of a well site and the like.
Description
Technical field
The utility model belongs to land petroleum well-control equipment technical field, especially relates to a kind of BOP and controls emergent control air source equipment.
Background technique
In existing technology, BOP controls source of the gas generation emergency situations, and when deficency, BOP control gear can not normally move, and has an accident if at this moment there is well head, and wellhead blowout preventor group can not be opened normally, be closed, and guarantees Well site safety, consequence and danger thereof.
Model utility content
Problem to be solved in the utility model is to provide a kind of BOP and controls emergent control air source equipment, is especially applicable to the potential safety hazard that BOP control gear exists.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of BOP controls emergent control air source equipment, comprises source of the gas, emergency control apparatus and BOP control gear, described source of the gas by emergency control apparatus to BOP control gear air feed;
Described emergency control apparatus comprises one-way valve, two-position three way Pneumatic reversal valve, emergent gas bag and air horn, described source of the gas is connected with emergent gas bag by one-way valve, described source of the gas is also connected with two-position three way Pneumatic reversal valve, described emergent gas bag is connected with described two-position three way Pneumatic reversal valve, described two-position three way Pneumatic reversal valve is connected with described air horn, and described air horn is connected with BOP control gear by one-way valve.
Further, described emergent gas bag is provided with safety valve.
Further, described emergent gas bag is provided with pressure gauge.
Further, described emergent gas bag is provided with safety valve and pressure gauge.
Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, emergent gas bag is not given outside air feed, and the main gas of source of the gas directly supplies BOP control gear; In the time that the main gas circuit of source of the gas there is not gas, emergent gas bag work is to BOP control gear air feed, and air horn gives the alarm, and guarantees that BOP controls normal work when overhauling circuit in time, more convenient to operate; There is the advantages such as simple in structure, easy to maintenance, assurance Well site safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure:
1, source of the gas 2, emergency control apparatus 3, BOP control gear
4, one-way valve 5, emergent gas bag 6, two-position three way Pneumatic reversal valve
7, air horn 8, safety valve 9, pressure gauge
Embodiment
As shown in Figure 1, a kind of BOP of the utility model controls emergent control air source equipment, comprises source of the gas 1, emergency control apparatus 2 and BOP control gear 3, and described source of the gas 1 is given BOP control gear 3 air feed by emergency control apparatus 2; Described emergency control apparatus 2 comprises one-way valve 4, two-position three way Pneumatic reversal valve 6, emergent gas bag 5 and air horn 7, described source of the gas 1 is connected with emergent gas bag 5 by one-way valve 4, described source of the gas 1 is also connected with two-position three way Pneumatic reversal valve 6, described emergent gas bag 5 is connected with described two-position three way Pneumatic reversal valve 6, described two-position three way Pneumatic reversal valve 6 is connected with described air horn 7, and described air horn 7 is connected with BOP control gear 3 by one-way valve 4.Described emergent gas bag 5 is provided with safety valve 8.Described emergent gas bag 5 is provided with pressure gauge 9.Described emergent gas bag 5 is provided with safety valve 8 and pressure gauge 9.
The working procedure of this example: BOP control gear 3 is placed according to the position of well layout, in the time of the main gas circuit normal ventilation of source of the gas 1, two-position three way Pneumatic reversal valve 6 is in ending emergent gas bag 5 for gaseity, and emergent gas bag 5 is not given extraneous air feed, and the main gas of source of the gas 1 is directly supplied with BOP control gear 3.
In the time that the main gas circuit of source of the gas 1 there is not gas, two-position three way Pneumatic reversal valve 6 is changed, and connects the air feed of emergent gas bag 5 and BOP control gear 3, and by air horn 7, air horn 7 gives the alarm simultaneously, guarantees that BOP controls normal work when overhauling circuit in time.
Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variation and improvement etc. of doing according to the utility model application range, within all should still belonging to patent covering scope of the present utility model.
