Description
Technical field
The utility model is related to a kind of choke valve, and in particular to a kind of gas well cage type throttling valve.
Background technology
Cage type throttling valve is the kind for growing up the sixties in 20th century, and it is 80 that China really starts to apply
Age, 20 years more late than World Developed Countries or so.The cage type throttling valve for using at present mainly has two types, and one is interior cage set
Formula, two is outer cage shell type, and either that is a kind of, is all that slip or plunger are slided on the coat on cage set using valve pocket, is produced
Different area of passages controls the purpose of flow and pressure to reach.High-pressure fluid enters valve body and covers it with cage from throttling valve inlet
Between annular space, change fluid flow direction, and mutually clash into, extruding, by cage cover throttle orifice after be expanded into cage
Set center, completes throttling process.The current natural gas extraction of China, in order to adapt to high pressure, the bad working environments in high yield gas field, uses
The product of famous foreign company, the choke valve average price of import is more than 50,000 dollars, but none example in actual use
Occur in that different degrees of erosive wear outward, erosion failure has that stability is poor, the defect such as exhaustion run does not know, seriously
The efficiency of gas-field exploitation is influenceed, therefore, independent research gas field well head choke valve is very urgent.
The content of the invention
The purpose of this utility model is：A kind of gas well cage type throttling valve is provided, using the gas well cage type throttling valve
Control well head natural gas flow speed and pressure, can provide production efficiency, extend the service life of choke valve, save production cost.
