Abstract
The utility model relates to a check valve used for installing a flow path pipeline for an oil well in an oil field, a water well and a steam injection well, particularly a self-locking and high-pressure check valve which is not limited by an installing direction. The self-locking and high-pressure check valve is composed of a connecting body, a valve core, a positioning valve rod, a pressure spring, a positioning valve bolt and a clamping reed. The utility model is characterized in that one end of the positioning valve rod is arranged in the middle of the valve core and the other end is arranged in the middle of the positioning valve bolt; the circumference of the positioning valve bolt is provided with a plurality of liquid and steam discharging holes. The utility model has the advantages of simple structure, low cost and convenient operation, and is not limited by a direction when installed.
Description
Technical field
The utility model relates to the one-way valve of a kind of oilfield, well, notes vapour well stream journey pipeline installation usefulness, especially a kind of self-locking high pressure one-way valve that is not subjected to the installation position restriction.
Background technique
At present, the one-way valve that known oilfield, well, notes vapour well stream journey pipeline are installed usefulness is common casting one-way valve, and auto-lock function is poor, limited by installation position.
Summary of the invention
In order to overcome the problem that present technology exists, the utility model provides a kind of self-locking high pressure one-way valve, and the pressure spring in this self-locking high pressure one-way valve around the valve rod of location can solve the self-lock ability difference and be subjected to the problem of installation position restriction.
The technical solution adopted for the present invention to solve the technical problems is: self-locking high pressure one-way valve, form by connection main body, spool, location valve rod, pressure spring, location bibcock, jump ring sheet, its special way is: an end of location valve rod is contained in the middle of the spool, the other end is contained in the middle of the bibcock of location, around the bibcock of location a plurality of discharge opeings, steam vent is arranged.
The invention has the beneficial effects as follows: be not subjected to orientation restriction, simple in structure, with low cost, easy to use during installation.
