Example Embodiment

[0017] Combine below figure 1 , figure 2 , image 3 with Figure 4 , To further explain the present invention:

[0018] Because all the stroke sensors in the prior art cannot be used on the existing oilfield electric water injection tools due to structural reasons, the focus of the invention is to conveniently install the stroke sensor on the oilfield electric water injection tool stroke sensor, and can Realize accurate stroke control and valve position feedback of water distribution valves in oilfield water injection tools.

[0019] To achieve this objective, the present invention includes a sensor body 1, which is a cuboid structure housing with a window 11 on the upper end surface. This structure housing is easier to install. A lead screw transmission device is provided in the sensor body, the lead screw 2 of the lead screw transmission device extends out of the sensor body 1, and a driven gear 4 is provided on the lead screw extending out of the sensor body. , The driven gea...

Abstract

The invention relates to an oilfield electric water injection tool stroke sensor and belongs to the technical field of the stroke control and valve position feedback control of a water distribution valve in an oilfield water injection tool. The oilfield electric water injection tool stroke sensor is characterized in that the sensor comprises a sensor body which is a shell with a rectangular structure, an upper end surface of the sensor body is provided with a window, a screw driving device is arranged in the sensor body, a screw of the screw driving device extends out of the sensor body, the screw extending out of the sensor body is provided with a driven gear which engages with a driving gear on an oilfield electric water injection tool. An upper end surface of the sensor body is providedwith a stroke sensor circuit board which is connected to a power supply through a wire. The oilfield electric water injection tool stroke sensor has the advantages of simple structure and easy installation, the sensor is used with the oilfield electric water injection tool to accurately provide the stroke control and valve position feedback control of the water distribution valve in the oilfieldwater injection tool, and the automatic control level and precision of the working of the oilfield electric water injection tool are improved.

Description

Technical field: [0001] The invention relates to a stroke sensor for an electric water injection tool in an oil field, which belongs to the technical field of stroke control and valve position feedback control of a water distribution valve in an oil field water injection tool, in particular to a stroke sensor for stroke control and valve position feedback. Background technique: [0002] The current oilfield water injection tools are all mechanical water injection tools. With the advancement of technology, designers have developed oilfield water injection tools with electric actuators. Electric water injection tools involve the stroke control and valve position feedback of water distribution valves. Therefore, it is necessary to A sensor suitable for use inside an electric water injection tool. Most of the stroke sensors that can be purchased now are variable resistors, and the structure is basically in the form of axial compression or tension, which is not suitable for strok...
