Abstract
The utility model discloses a quantitative and adjustable sleeve throttling valve for extracting oil and gas, which is suitable for extracting oil and gas when frequently adjusting the flow. The throttling valve consists of a shell (1), an adjusting screw nut (3), a throttling valve core (4), a seal ring (5), a valve rod (6), a guide fixed screw nail (7), a hand wheel (8) and a flow aperture meter (9), wherein the lower end of the valve rod (6) is connected with a throttling rod (2), the throttling rod (2) is in the shape of a cylinder or a semicircle, the throttling rod (2) is internally provided with a blind hole, the throttling rod (2) is provided with a plurality of holes with different diameters, and an inner hole of the throttling valve core (4) is communicated with an inner blind hole of the throttling rod (2). When the flow and the pressure need to be adjusted during extracting the oil and the gas, the guide fixed screw nail (7) is unscrewed, and the hand wheel (8) is rotated, so that the valve rod (6) drives the throttling rod (2) to move up and down in (among) the throttling valve core (4), and the corresponding required flow scale is selected on the flow aperture meter (9), therefore, the quantitative and adjustable sleeve throttling valve can fast and exactly adjust the flow when extracting the oil and the gas.
Description
Technical field:
The utility model relates to the quantitative adjustable pinch valve of a kind of oil recovery gas production, is specially adapted to frequently regulate the oil recovery gas production operation of flow.
Background technology:
Along with the demand of market oil product increases substantially; each oil field continues to increase the oil extraction task; the statistical requirements of crude oil production simultaneously also improves constantly; choke valve is first control valve of producing in the crude oil process; realize adjusting pressure and flow after the throttling by choke valve; thereby make petroleum pipeline form moderate pressure, flow liquid stream stably,, effectively protected Crude Oil Transportation equipment on the pipeline for traffic statistics equipment provides stable environment.The choke valve that present field produces well is adopted has two kinds of forms: the one, and fixation type throttle valve, the 2nd, adjustable choke valve.All there is different shortcomings in the choke valve of two kinds of forms: the flap type that the fixation type throttle valve connects above need cutting out when changing oil nozzle, the dismounting throttle member is changed oil nozzle, whole replacing process need for a long time, waste time and energy, increase the time and the labour intensity of supplement production, reduced production efficiency; Adjustable choke valve has needle-type throttle valve and cage shell type choke valve, the adjustable choke valve of two kinds of forms, and it is fast and non-linear that the accuracy of processing precision direct influence throttling, the reason of form of structure cause aperture to change, and is difficult to accurately access the flow of needs.
Summary of the invention:
The purpose of this utility model is to provide a kind of oil recovery gas production quantitative adjustable pinch valve, can realize quick and precisely regulating flow, regulates accurately, and is quick, convenient.
The utility model is mainly by housing, adjusting nut, throttling valve core, sealing ring, valve rod, the guide securement screw, handwheel, flow aperture table is formed, its valve rod lower end connects a throttling rod, the throttling rod profile is cylinder or semicircle, there is a blind hole inside, the clear opening of diameter of varying in size distributes on the throttling rod, the throttling valve core endoporus communicates with blind hole in the throttling rod, throttling valve core is fixed in the housing by adjusting nut, throttling valve core and housing inner chamber are sealed by sealing ring, when recovering the oil or gas production adjusting flow, during pressure, unscrew the guide securement screw, rotation hand wheel, valve rod drive throttling rod in throttling valve core () move up and down, according to needed flow, on flow aperture table, choose corresponding flow scale, tighten the guide securement screw then, crude oil or gas will recover the oil or gas production by regulating flow from the choke valve left side through the throttling rod flow ipe, this throttle valve adjustment is convenient, and flow-control is accurate.
The utility model adopts the quantitative regulative mode of throttling rod, accurately controls the size of throttle opening by the throttle orifice above the throttling rod, and the Field adjustment flow is convenient and swift, improves the operating efficiency of oil recovery gas production operation, reduces the expense that throttle valve opening takes place of regulating.
Description of drawings:
Fig. 1 is the utility model structure principle chart
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is described in detail:
The utility model is by housing (1), adjusting nut (3), throttling valve core (4), sealing ring (5), valve rod (6), guide securement screw (7), handwheel (8), flow aperture table (9) is formed, its valve rod (6) lower end connects a throttling rod (2), throttling rod (2) profile is cylinder or semicircle, there is a blind hole inside, throttling rod (2) clear opening of diameter of varying in size that go up to distribute, throttling valve core (4) endoporus communicates with the interior blind hole of throttling rod (2), throttling valve core (4) is fixed in the housing (1) by adjusting nut (3), throttling valve core (4) and housing (1) inner chamber are sealed by sealing ring (5), when recovering the oil or gas production adjusting flow, during pressure, unscrew guide securement screw (7), rotation hand wheel (8), valve rod (6) drive throttling rod (2) in throttling valve core (4) () move up and down, according to needed flow, on flow aperture table (9), choose corresponding flow scale, tighten guide securement screw (7) then, crude oil or gas will be from the choke valve left side through throttling rod (6) flow ipes, recover the oil or gas production by regulating flow, this throttle valve adjustment is convenient, and flow-control is accurate.
Claims (2)
1. quantitative adjustable pinch valve of oil recovery gas production, it is by housing (1), adjusting nut (3), throttling valve core (4), sealing ring (5), valve rod (6), guide securement screw (7), handwheel (8), flow aperture table (9) is formed, it is characterized in that valve rod (6) lower end connects a throttling rod (2), throttling rod (2) clear opening of diameter of varying in size that go up to distribute, throttling valve core (4) endoporus communicates with the interior blind hole of throttling rod (6), throttling valve core (4) is fixed in the housing (2) by adjusting nut (3), and throttling valve core (4) and housing (2) inner chamber are sealed by sealing ring (5).
