Abstract
The utility model discloses an oil pipe thread detecting instrument, which relates to a detecting instrument which is used in an oil field for detecting oil pipe threads. The original oil pipe thread detecting instrument has poor sealing property; the surrounding medium has erosion function to the instrument, which influences the service life of the instrument. The utility model comprises a magnet (1), a probe (2) and an outer shell (3), wherein, a rotating disc (4) is fixedly connected with the inner wall of the probe (2) positioned in the outer shell (3); the rotating disc (4) is connected with the probe (2) in a sealing way; the rotating disc (4) is a circular disc of which the center is provided with a through hole (4-1). The utility model can play the function of sealing electronic elements in the oil pipe thread detecting instrument, and avoids oil dirt on an oil pipe entering the inner side of the instrument.
Description
Technical field: the utility model relates to a kind of detector that detects at tubing thread that uses on the oil field.
Background technology: when original Non-destructive Testing of Oil Well Tubing Thread instrument uses at the scene, have oil leakage phenomenon, be unfavorable for the cleaning and the use of instrument, the on-the-spot back cleaning amount of using is big; And when using the Non-destructive Testing of Oil Well Tubing Thread instrument, because the instrument sealing is relatively poor, surrounding medium also has corrosive attack to instrument, influences the serviceable life of instrument, especially dirty oil pipe is detected, because greasy dirt is many, rotating speed descends, and directly influences the instrument operate as normal.
Summary of the invention: greasy dirt can enter the problem of instrument internal along barrel when the utility model detected at the scene at the Non-destructive Testing of Oil Well Tubing Thread instrument, provide a kind of and can guarantee the instrument favorable sealing property, make things convenient for the Non-destructive Testing of Oil Well Tubing Thread instrument of instrument cleaning, its objective is such realization: the Non-destructive Testing of Oil Well Tubing Thread instrument comprises magnet 1, probe 2, shell 3, on the inwall of the probe 2 that is in shell 3 inside, be connected with rotating disc 4, rotating disc 4 is tightly connected with probe 2, and described rotating disc 4 is the disk of center band through hole 4-1.Advantage of the present utility model is: increase the rotating disc 4 that is tightly connected with probe on the structure of original probe, the diameter of rotating disc 4 central through hole 4-1 is set to adapt with the external diameter of magnet 1, rotating disc 4 rotates with probe 2 when probe 2 rotates, can play the effect of sealing detection instrument internal electronic element, avoid the greasy dirt on the oil pipe to enter instrument internal.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of rotating disc 4.
Embodiment: present embodiment comprises magnet 1, probe 2, shell 3, on the inwall of the probe 2 that is in shell 3 inside, be connected with rotating disc 4, rotating disc 4 is tightly connected with probe 2, described rotating disc 4 is the disk of center band through hole 4-1, during use, centering portion with instrument stretches in the oil pipe earlier, click switch, the head spreading of magnet 1, prop up tested tube inner wall, make magnet 1 location, probe 2 is in the rotation of tubing thread outside, and driven rotary dish 4 together rotates, because rotating disc 4 is fixed with probe 2 and is tightly connected, so rotating disc 4 can block the greasy dirt that probe 2 is wiped off when the rotation of tubing thread outside, avoid greasy dirt to enter detecting instrument inside, plays the effect of good hermetically-sealed instrument internal electronic element.In addition, the material of shell 3 can be improved, change original aluminum alloy casing into stainless steel casing, can further improve the antiseptic property and the serviceable life of instrument like this.
Claims (2)
1, a kind of Non-destructive Testing of Oil Well Tubing Thread instrument, it comprises magnet (1), probe (2), shell (3), it is characterized in that being connected with rotating disc (4) on the inwall that is in the inner probe (2) of shell (3), rotating disc (4) is tightly connected with probe (2).
2, Non-destructive Testing of Oil Well Tubing Thread instrument according to claim 1 is characterized in that described rotating disc (4) is the disk of center band through hole (4-1).
