Problems solved by technology

Since the valve seat is fixed, the reverse pressure acts on the valve core at this time, the valve core is displaced in the direction away from the valve seat, and a gap appears between the valve core and the valve seat, resulting in reverse leakage

Abstract

The invention relates to the technical field of natural gas and oil exploitation, and discloses a self-adaptive shut-off structure of an intelligent flow regulator of a natural gas well. The self-adaptive shut-off structure of the intelligent flow regulator of the natural gas well comprises a valve body, a valve seat and a valve element. A working cavity extending along a preset axis is formed in the valve body, and an inlet and an outlet communicating the working cavity with the outside are formed in the valve body; the valve seat can be movably arranged in the outlet in a preset axis direction, a fluid channel communicating the working cavity with the outside is formed in the valve seat, and the outer circumferential face of the valve seat is in sealing fit with the inner circumferential face of the outlet; the valve element is located in the working cavity, and the valve element is constructed to do reciprocating motion between a valve closing position matched with the valve seat and a valve opening position far away from the valve seat in the direction of the preset axis; when the valve element is located at the valve closing position, the fluid channel is closed, and when the valve element is separated from the valve closing position, the fluid channel is opened. According to the self-adaptive turn-off structure of the intelligent flow regulator of the natural gas well, reverse leakage can be effectively avoided.

Description

technical field [0001] The application relates to the technical field of natural gas and oil exploitation, in particular to an adaptive shut-off structure of an intelligent flow regulator for a natural gas well. Background technique [0002] In order to finely control the production status of natural gas wells, more and more natural gas wells are equipped with flow regulators at their production outlets. The flow regulator mainly includes a valve seat and a valve core. The spool is the moving part that mates with the seat to close the flow regulator, or disengages from the seat to open the flow regulator. [0003] When the spool cooperates with the valve seat, there may be a reverse pressure along the direction of the valve seat to the spool. For example, when the pressure of the gas pipeline is greater than the wellhead pressure of the natural gas well, there will be a reverse pressure along the direction from the valve seat to the valve core. Since the valve seat is fix...
