Abstract

The utility model relates to a multi-way distributing valve, which is mainly composed of an electric motor, a speed reducer, a valve body, a valve cover, a distributing plate, etc. The distributing plate arranged on the output axle of the speed reducer is in the structure with the shape of Chinese character tu and the distributing plate is provided with a groove forming the shape of Chinese character tu. The valve body is also provided with a ring groove on the corresponding position of the ring groove forming the shape of Chinese character tu of the distributing plate and a plurality of radial holes are also provided, wherein, one radial hole is communicated with the ring groove of the valve body and the other radial holes are respectively communicated with each axial hole. The position of each axial hole is corresponding to the position of the semicircle hole of the end groove forming the shape of Chinese character tu on the distributing plate. The advantage of the scheme is that the pipeline of a multi-opening oil well can be simultaneously connected. The defect of multiple valves and multiple pipelines of the original measurement room is changed to be convenient for realizing automatic position selection and measurement. The utility model provides a new executing component of the automatic measurement of the oil well.

Description

Many logical distributing valves

The utility model belongs to industrial valves, and particularly a kind of crude oil measurement that is mainly used between oil well measurement leads to distributing valve more.

In the crude oil recovery process, need carry out real time measure to the crude output of oil well, thereby set up between a crude oil measurement in arbitrary oil well group's central position.Traditional way is to adopt many valves multitube road system, promptly for each well location a valve is arranged all in metering room, opens the valve of a certain well location during metering, makes this well location crude oil enter the metering loading amount and measures.The shortcoming of this method is that the valve of metering room is many, pipeline is many, and floor space is big, and the Operation and Maintenance workload is big, and the whole cost of metering room is high.

The purpose of this utility model is to propose a kind of many logical distributing valves, for only establishing logical distributing valve more than in a certain oil well group's the metering room, each well location crude oil leads to measuring apparatus through distributing valve and measures, and can adopt electronics automatic carry and control, to change many drawbacks of prior art, lay the first stone for realizing the oil well measurement automation.

This programme is achieved in that by actuating motor and drives output shaft by speed reducer, and a distribution switchboard is installed on axle, and this dish is the convex shape structure, is a convex shape groove in the middle of it; Valve body is fixed on the housing of speed reducer, is equipped with a circular groove at the centre bit of valve body, and its position is corresponding with the type annular groove on the distribution switchboard; Also have several radial holes on the valve body, wherein there is one directly to communicate with circular groove, this hole is called the zero-bit hole, it is the oil outlet of institute's survey oil well, in order to being introduced measuring apparatus, measures the crude oil of institute's survey oil well, all the other radial hole one ends are connected with the oil pipe of corresponding well location by outer pipeline, and the other end communicates with its axial bore respectively, and this axial bore position is just in time corresponding with the semicircle orifice of type end slot on the distribution switchboard; The control actuating motor drives distribution switchboard, when its type end slot when a certain axial bore on the valve body communicates, well location corresponding to this axial bore is the position of logging well, and crude oil is through the circular groove → valve body circular groove → valve body zero-bit hole → measuring apparatus of the type end slot → distribution switchboard of radial hole → axial bore → distribution switchboard; Other well location crude oil then directly enter the oil-collecting valve gap through its axial bore and flow into the crude oil house steward; When the type end slot of distribution switchboard was in the zero-bit hole site of valve body, the crude oil of all oil wells all directly entered the oil-collecting valve gap and flows into the crude oil house steward, and distributing valve quits work, and does not measure.

The advantage of this programme is: the pipeline that can connect many mouthfuls of oil wells on this valve simultaneously, by any automatic control device control disc in rotation location, respectively the preliminary election well location is measured, changed former many valves of metering room multitube road, shortcomings such as floor space is big between the valve group, a large amount of valves, accessory and material have been saved, reduced the whole manufacture cost of metering room, dwindled the floor space of metering room, alleviate Operation and Maintenance work greatly, be convenient to realize computer automatic carry and metering, for the oil well measurement automation provides a kind of new execution original paper.

The embodiment of this programme: general oil field is at most to be one group by 11 mouthfuls of oil wells, and a metering room is set up in the centre, and present embodiment is that example illustrates with more than 11 tunnel logical distributing valves.This valve mainly drives output shaft 3 by actuating motor 1 by worm type of reduction gearing 2, on the axle 3 distribution switchboard 5 is installed, and it is the convex shape structure, has circular groove 5a and tappet end slot 5b in the middle of it; On reducer shell 2a, be fixed with valve body 4, the heart exists together mutually with the radial position of the circular groove 5a of distribution switchboard 5 and has circular groove 4a therein, also have 12 radial hole 4c on the valve body 4, wherein there is a radial hole 4b to communicate with circular groove 4a, this hole is called the zero-bit hole, by it crude oil is introduced measuring apparatus, the end of other 11 radial hole 4c communicates with 11 axial bore 4d, the other end of these 11 radial holes is connected with each well location oil outlet tube respectively by outer pipeline, and place, the center of circle radius R of axial bore 4d equals the radial position L in the semicircle center of circle of type end slot 5 on the distribution switchboard 5; In the lower end of valve body 4 oil-collecting valve gap 6 is installed, is connected with the crude oil house steward by its flange.

The working procedure of this valve is: actuating motor 1 drives output shafts 3 and distribution switchboard 5 with about 2 rev/mins low speed rotation by speed reducer 2, actuating motor 1 can be controlled its rotation or stopped by any automatic controller, when the convex shape end slot 5b on the distribution switchboard 5 when a certain axial bore 4d on the valve body 4 communicates, well location corresponding to this axial bore is the position of logging well, crude oil is through the circular groove 4a → zero-bit hole 4b → measuring apparatus of the type end slot 5b → circular groove 5a → valve body 4 of the radial hole 4c → axial bore 4d → distribution switchboard 5 of valve body 4, carry out real time measure, the crude oil of other well location imports the crude oil house steward after axial bore 4d enters oil-collecting valve gap 6; The crude oil of all well locations all directly enters oil-collecting valve gap 6 when the type end slot 5b on the distribution switchboard 5 is in the 4b position, zero-bit hole of valve body 4, and distributing valve is in off position, does not carry out gage work.
