the technical solution of the utility model realizes by following measures: a kind of air drilling high-low pressure conversion manifold apparatus comprises gas-booster, air inlet pipe, air guide one way valve, air intake valve, breather check valve, supercharging stack, the valve of giving vent to anger, outgassing nonreturn valve, wireway and air guide valve; Be installed with respectively air inlet pipe and supercharging stack on the air inlet port of gas-booster and the port of giving vent to anger, be installed with respectively air intake valve and breather check valve on air inlet pipe; Be installed with respectively give vent to anger valve and outgassing nonreturn valve on the supercharging stack; Air inlet port in air inlet pipe is installed with total inlet pipe; Exhaust port place at the supercharging stack is installed with total air escape pipe; Be communicated with and be installed with wireway between total inlet pipe and total air escape pipe; Be installed with air guide valve and air guide one way valve on wireway.
below the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned air intake valve, give vent to anger valve and air guide valve can be respectively ball valve.
the bottom of above-mentioned air inlet pipe, supercharging stack and wireway can be equipped with the skid base plate, and air inlet pipe, supercharging stack and wireway are fixedly mounted on the skid base plate by support respectively.
the utility model reasonable and compact in structure, easy to use; The utility model reasonable and compact in structure, easy to use; Control by the keying to air intake valve, give vent to anger valve and air guide valve, can realize entering the switching of gases at high pressure and the low-pressure gas of drilling riser pipe; Easy to use, the activity duration is short, safe.
The accompanying drawing explanation
the main TV structure schematic diagram that accompanying drawing 1 is the utility model most preferred embodiment.
coding in accompanying drawing is respectively: 1 is gas-booster, and 2 is air inlet pipe, and 3 is the air guide one way valve, and 4 is air intake valve, 5 is breather check valve, and 6 is the supercharging stack, and 7 is high pressure valve, and 8 is exhaust check valve, 9 is total air escape pipe, and 10 is total inlet pipe, and 11 is wireway, and 12 is the air guide valve.
The specific embodiment
the utility model is not subject to the restriction of following embodiment, can determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all to be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. is to determine according to the Butut direction of Figure of description 1.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this air drilling high-low pressure conversion manifold apparatus comprises gas-booster 1, air inlet pipe 2, air guide one way valve 3, air intake valve 4, breather check valve 5, supercharging stack 6, the valve 7 of giving vent to anger, outgassing nonreturn valve 8, wireway 11 and air guide valve 12; Be installed with respectively air inlet pipe 2 and supercharging stack 6 on the air inlet port of gas-booster 1 and the port of giving vent to anger, be installed with respectively air intake valve 4 and breather check valve 5 on air inlet pipe 2; Be installed with respectively give vent to anger valve 7 and outgassing nonreturn valve 8 on supercharging stack 6; Air inlet port in air inlet pipe 2 is installed with total inlet pipe 10; Exhaust port place at supercharging stack 6 is installed with total air escape pipe 9; Be communicated with and be installed with wireway 11 between total inlet pipe 10 and total air escape pipe 9; Be installed with air guide valve 12 and air guide one way valve 3 on wireway 11.Breather check valve 5, outgassing nonreturn valve 8 and air guide one way valve 3 play the effect that prevents gas backstreaming; When shaft bottom needs gases at high pressure, as long as close air guide valve 12, open air intake valve 4 and just can carry out conventional manifold operation with the valve 7 of giving vent to anger; When shaft bottom does not need gases at high pressure, as long as close air intake valve 4 and the valve 7 of giving vent to anger, open the air guide valve 12 on wireway 11, gas in total inlet pipe 10 just can directly enter shaft bottom by wireway 11, thereby realized the conversion of input gases at high pressure and low-pressure gas, shorten the operating time of replacing and connecting line, improved operating efficiency, reduced potential safety hazard simultaneously.
