Abstract
The utility model provides a unidirectional flow detecting device, which comprises a casing. A check valve core mounted inside the casing matches with a valve seat disposed inside a valve body through a sealing surface, a sensing part is arranged at a position inside the casing, the position is capable of sensing movement of the check valve core, and the sensing part can convert movement of the check valve core into electric signals to be outputted. The unidirectional flow detecting device has the advantages of being capable of being directly installed on a wellhead flow, detecting and displaying industrial situation of a single well at any time, utilizing the check valve core serving as a flow detecting part to form the flow detecting device, and synchronously realizing detecting flow and finishing check. As the range of the selected sensing part is comparatively wide, sensing devices of the flow meter have strong interchangeability, and detection of unidirectional flow can be more effectively achieved. The detecting device has fine sealing effect and flexible movement, and is convenient for detecting signals and monitoring.
Description
Technical field
The utility model relates to a kind of flow detector, particularly a kind of one-way flow checkout gear that is applied to the individual well flow detection in the oil field development.
Background technology
At present, the individual well detection technique in the oil field development, the method that mainly adopts eliminator gauging and indicator card to convert that is: converses the production fluid amount of every day after regularly detecting.That this method exists is discontinuous, can not be with the shortcoming of machine testing individual well production status.Sometimes individual well production fluid whether, the time that all needs to examine several days just can be examined clear.Because the individual well production fluid is three of oil, gas, water, has the liquid viscosity difference, oil, gas, three content differences of water, characteristics such as intermittent flow, general flow meter can't measure.All the time there is not a kind of technology that can continuous detecting oil well liquid-producing situation to solve this difficult problem for many years.
Summary of the invention
The purpose of this utility model is to provide a kind of one-way flow checkout gear, and being beneficial to can continuous detecting oil well liquid-producing situation, reaches with machine testing individual well production status, simplifies flow process, improves technological level, reduces workload, reduces production costs.
For achieving the above object, the concrete scheme that the utility model adopts provides a kind of one-way flow checkout gear, this checkout gear includes in housing, the housing non-return valve core is housed, the non-return valve core valve seat interior with being located at valve body cooperates by sealing surface, wherein: the position of the non-return valve core the sensed action in the described housing is provided with sensing element, and sensing element is converted to signal of telecommunication output with the action of non-return valve core.
Effect of the present utility model is this one-way flow checkout gear, can be directly installed on the well head flow process, detects and show the industry situation of individual well at any time.Concrete is to utilize non-return valve core to be the flow detection parts, the flow detector of formation, and realization flow detection and non-return are finished synchronously.Because selected sensing element scope is more wide in range, the senser element interchangeability of this flow meter is strong, realizes the detection of one-way flow better.This checkout gear good sealing effect is active in one's movements, and is convenient to signal detection.
