Abstract
The utility model discloses an adjustable step-type throttle valve, which is applied to oil/gas recovery operation with accurate adjustment to the production volume of crude oil/gas. The adjustable step-type throttle valve comprises a flow cylinder (1), a flow sleeve (2), a hand wheel (3), a valve rod nut (4), a locking screw (5), a valve rod (6), a valve seat (8) and a valve body (9), wherein a plurality of concentric cylindrical steps (7) are arranged at the lower end of the valve rod (6); a group of flow passing channels with different areas are formed between the cylindrical steps (7) and an inner hole of the valve seat (8); the flow cylinder (1) is connected to the upper end of the valve rod (6); and flow graduations are marked on the flow cylinder (1), and are corresponding to the area of the ring-shaped flow passing channels. When the step-type throttle valve provided by the utility model is used for adjusting the flow, the area of the ring-shaped flow passing channels formed between the cylindrical steps (7) and the inner hole of the valve seat (8) is shown by the graduations on the flow cylinder (1), so that the flow of the throttle valve can be directly and accurately displayed.
Description
Technical field:
The utility model relates to a kind of adjustable step choke valve, and it is applicable to oil recovery and the gas production operation that crude oil (gas) output is had accurate adjusting.
Background technology:
The oil recovery (gas) in oil field at present drives the up-down of needle through rotation hand wheel with adjustable choke valve; Make the change of needle and valve seat generation relative position; Thereby the orifice size of control liquid is controlled the flow of fluid; The structure of common valve rod throttling place mainly is conical, and the old-fashioned structure of this kind is not easy operation accurately in use.
Summary of the invention:
The utility model purpose has provided a kind of adjustable step choke valve, can intuitively, accurately show the annular area of passage of choke valve through regulating the relative position of choke valve valve rod step and valve seat.
The utility model is made up of flow tube, flow sleeve, handwheel, valve stem nut, lock-screw, valve rod, valve seat, valve body; There are some concentric column steps the lower end of its valve rod; Form the flow channels of one group of different area between each cylinder step and the valve seat endoporus; The upper end of valve rod connects the flow tube, is carved with flow scale on the flow tube, and its flow scale is corresponding with annular flow channels area.When oil producing operation, the left end of adjustable step choke valve valve body and the production valve of well head flank are linked, the bottom and the production procedure pipeline of adjustable step choke valve valve body link; Before regulating flow, the cylinder step of valve rod is in valve seat bottom, and the scale of flow tube " 0 " aligns with the upper end of flow sleeve; When regulating flow, rotate handwheel, handwheel drives valve stem nut and rotates; Valve rod is moved up and down, move up and down, the scale on the flow tube is changed thereby drive the flow tube; Moving up and down of valve rod makes the flow channels that forms one group of different area between each cylinder step of valve rod and the valve seat endoporus, and the variation of annular flow channels area is showed by the scale on the flow tube; After regulating flow according to the production needs, tighten lock-screw, thereby can accurately guarantee the flow of oil (gas).
The utility model shows annular area of passage through the scale of flow tube, makes the adjusting flow more directly perceived, accurate, convenient, fast, has improved operating efficiency greatly.

The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail:
The utility model is made up of flow tube (1), flow sleeve (2), handwheel (3), valve stem nut (4), lock-screw (5), valve rod (6), valve seat (8), valve body (9); There are some concentric column steps (7) lower end of its valve rod (6); Form the flow channels of one group of different area between each cylinder step (7) and valve seat (8) endoporus; The upper end of valve rod (6) connects flow tube (1), and the flow tube is carved with flow scale on (1), and its flow scale is corresponding with annular flow channels area.When oil producing operation, the left end of adjustable step choke valve valve body (9) and the production valve of well head flank are linked, the bottom and the production procedure pipeline of adjustable step choke valve valve body (9) link; Before regulating flow, the cylinder step (7) of valve rod (6) is in valve seat (8) bottom, and the scale of flow tube (1) " 0 " aligns with the upper end of flow sleeve (2); When regulating flow, rotate handwheel (3), handwheel (3) drives valve stem nut (4) and rotates; Valve rod (6) is moved up and down, move up and down, the scale on the flow tube (1) is changed thereby drive flow tube (1); Moving up and down of valve rod (6); Make between each cylinder step (7) of valve rod (6) and valve seat (8) endoporus flow channels that forms one group of different area, the variation of annular flow channels area is showed by the scale on the flow tube (1), regulate flow according to the production needs after; Tighten lock-screw (5), thereby can accurately guarantee the flow of oil (gas).The utility model is easy to operate, can intuitively, accurately show the flow of choke valve.
