Abstract
The utility model discloses a flow sensor for oil field mud, which comprises a measuring pipe. A measuring board is rotatably mounted on the top part of one end pipe opening of the measuring pipe. A piezoelectric sensor is equipped in a groove at a top side wall of the measuring pipe. The piezoelectric sensor is sealed in the groove by a waterproof film. Elastic rubber is connected with the upper board wall of the measuring pipe and the waterproof film. The flow sensor for the oil field mud has the following advantages: direct and reliable measuring mode, no requirement for connection with other electronic equipment, simple and practical sensor structure.
Description
Technical field
The utility model relates to sensor field, is specially a kind of php slurry flow transmitter.
Background technology
The variation of mud relative discharge is measurement parameter important in oil drilling, the mud logging operation in the oil drilling outlet mud ditch, and it is concerning carrying out smoothly of oil well operation, adopts flow transmitter to measure in the actual production.The prior art flow transmitter adopts the mode of resistance variations to come measuring flow more, and this metering system needs to access power supply in sensor, causes sensor construction complicated.
The utility model content
The purpose of this utility model provides a kind of php slurry flow transmitter, to solve the baroque problem of prior art flow transmitter.
In order to achieve the above object, the technical scheme that adopts of the utility model is:
A kind of php slurry flow transmitter, include measuring tube, it is characterized in that: measuring tube one end mouth of pipe top is rotatablely equipped with the measurement plate that tilts to stretch in the measuring tube, measuring tube top sidewall is provided with groove, be provided with piezoelectric transducer in the groove, be connected with the holding wire that from measuring tube, passes on the piezoelectric transducer, and piezoelectric transducer is sealed in the groove by waterproof film, is connected with elastic caoutchouc between wooden partition and the waterproof film on the described measurement plate.
Described a kind of php slurry flow transmitter, it is characterized in that: described piezoelectric transducer is bonded in the groove by viscous adhesive.
In the utility model, when the measurement plate is subjected to the mud impact force action piezoelectric transducer is pushed, make piezoelectric transducer produce the signal of telecommunication, electric signal measurement mud flow rate by piezoelectric transducer, metering system is directly reliable, need not external other electronic equipment, and sensor construction is simple and practical.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1.A kind of php slurry flow transmitter, include measuring tube 1, measuring tube 1 one end mouth of pipe tops are rotatablely equipped with the measurement plate 2 that tilts to stretch in the measuring tube 1, measuring tube 1 top sidewall is provided with groove, be provided with piezoelectric transducer 3 in the groove, be connected with the holding wire 4 that from measuring tube 1, passes on the piezoelectric transducer 3, and piezoelectric transducer 3 is sealed in the groove by waterproof film 5, measures on the plate 2 and be connected with elastic caoutchouc 6 between the wooden partition and waterproof film 5.Piezoelectric transducer 3 is bonded in the groove by viscous adhesive 7.
