Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides an oil field water injection well head check valve, including main part shell 1, delivery port 5 and notch 10, main part shell 1 includes water inlet 2, and guide block 3 is installed to the top of water inlet 2, the inside of guide block 3 is provided with slider 4, and one side of slider 4 installs through-hole 6, spring 7 is installed to the top of slider 4, internal thread lid 9 is installed to the top of main part shell 1, and the middle part of internal thread lid 9 runs through there is adjusting screw 8, delivery port 5 is located one side of guide block 3, notch 10 is located the inside of slider 4.
In this embodiment, specifically: the inside of main part shell 1 is the hollow circular cylinder structure, and the inside diameter of main part shell 1 equals the outside diameter of guide block 3, through the position of main part shell 1 can effectual restriction guide block 3, simultaneously, for placing of guide block 3 provides suitable space to and prevent that dust and sand grain from getting into between guide block 3 and the main part shell 1.
In this embodiment, specifically: for threaded connection between main part shell 1 and the internal thread lid 9, and constitute detachable construction between internal thread lid 9 through adjusting screw 8 and guide block 3, can effectual control guide block 3 along the distance of the vertical central line direction of main part shell 1 through adjusting screw 8 to and change the area that the through-hole 6 allowed the fluid to pass through, thereby be favorable to the user according to the produced water pressure of liquid, fix guide block 3 to suitable position.
