Abstract
The utility model relates to a gas recovery device especially relates to a gas production well head device, including big cross and little cross, big cross top is connected with little cross bottom through last flange and two manual wafer valves, and big cross both sides are connected with manual wafer valve respectively, and little cross both sides are connected with manual choke valve through a manual wafer valve respectively, and little cross top is connected with the stop valve through a manual wafer valve, is connected with a relief pressure valve in the side direction of the manual wafer valve between big cross and the little cross. The beneficial effects are that: can effectively prevent hypertonia and cause the seepage through setting up the relief pressure valve to adopt the double valve design, strengthened the resistivity to ultra -high pressure greatly. Balanced each well pressure power is connected to come with other wellhead assemblies by the accessible relief pressure valve, has avoided the seepage of single wellhead assembly totally, has further improved life and security performance.
Description
Technical field
This utility model is related to a kind of gas recovery facility, more particularly to a kind of gas wellhead equipment.
Background technology
At present, domestic and international existing oil, gas drilling wellhead assembly, by sleeve pipe or casing flange, along with blowout prevention
The parts such as device, production tree are constituted.General its is equipped with flap type and is single valve part, and natural gas gas relative density
Low, gas injection pressure power is low, no matter gas production or gas injection well head pressure are all high, high flow rate easily causes seepage, affects gathering speed；Sometimes day
It is so shorter containing the corrosive impurities such as hydrogen sulfide, the service life for easily causing general flat wellhead assembly in gas.
The content of the invention
This utility model provides a kind of gas wellhead equipment, to be capable of achieving 2 times of the wellhead assembly as same specification grade
Gathering speed.
This utility model solves the technical scheme adopted by its technical problem：
A kind of gas wellhead equipment, including big four and little four-way, big four top is flat manually by upper flange and two
Plate valve is connected with the little four-way bottom, and the big four both sides are connected to manual flat valve, the little four-way both sides point
Not Tong Guo a manual flat valve be connected with manual throttle valve, pass through a manual flat valve and stop valve at the top of the little four-way
Connection, the manual flat valve between the big four and the little four-way are connected with an air relief valve on the side.By above-mentioned
Structure design, can carry out voltage division processing to single wellhead assembly, so as to prevent due to intrinsic pressure too high and cause seepage.
Further, be provided with tubing hanger in the big four, the upper flange is provided with grease pouring valve, the grease pouring valve with it is described on
Gasket ring is provided between flange.By setting up gasket ring, the situation that effectively prevent grease pouring valve easy seepage when high pressure is born occurs.
Further, the air relief valve bottom is connected with pressure-reduction outlet by silk mouth flange.
Further, it is described to be provided with pressure gauge with stop valve that is being connected at the top of little four-way.
Further, it is described to be provided with pressure gauge with big four laterally attached manual flat valve.
To sum up, the beneficial effects of the utility model are：
Hypertonia can effectively be prevented by setting air relief valve and seepage is caused, and designed using double valve, significantly
Enhance the resistivity to hyperpressure.Can be connected to balance each well pressure by air relief valve with other wellhead assemblies, completely
Avoid knowing clearly the seepage of single wellhead assembly, further increases service life and security performance.

Manual flat valve 4,2 both sides of little four-way are connected with manual throttle valve 5 by a manual flat valve 4 respectively, described little by four
It is connected with stop valve 6 by a manual flat valve 4 at the top of logical 2, it is flat manually between the big four 1 and the little four-way 2
Plate valve 4 is connected with an air relief valve 7 on the side.
Preferably, be provided with tubing hanger 8 in the big four 1, the upper flange 3 is provided with grease pouring valve 9, the grease pouring valve 9 with
Gasket ring 10 is provided between the upper flange 3.
Preferably, 7 bottom of the air relief valve is connected with pressure-reduction outlet 12 by silk mouth flange 11.
Preferably, it is described to be provided with pressure gauge 13 with stop valve 6 that is being connected at the top of little four-way 2.
Preferably, it is described to be provided with pressure gauge 13 with big four 1 laterally attached manual flat valve 4.
Above-mentioned specific embodiment is only concrete case of the present utility model, and scope of patent protection of the present utility model includes
But product form and the style of above-mentioned specific embodiment is not limited to, it is any to meet claims of the present invention and any affiliated skill
Appropriate change or modification that the those of ordinary skill in art field is done to which, should all fall into patent protection model of the present utility model
Enclose.
