Electronic digital display meter and ram preventer

Abstract

The invention provides an electronic digital display meter and a ram preventer and relates to the technical field of counting devices. The electronic digital display meter comprises a spindle, a housing, a magnetic part and an electronic component, wherein the spindle is connected to the interior of a first connecting hole of the housing, one end of the spindle extends out of the housing and is connected to a locking shaft of the ram preventer while the other end of the spindle is contained in the first connecting hole and is connected to the magnetic part, so that the magnetic part can be driven to rotate when the spindle rotates, the electronic component is connected to the other end of the housing and is opposite to the magnetic part; an encoder of the electronic component transforms arotating variable magnetic field signal generated by synchronous rotation of the magnetic part and the spindle into electric signals to be transmitted to a microcontroller. The technical problems of poor accuracy and high fault rate of metering modes of counting through rope winding and a mechanical counter are solved. The spindle drives the magnetic part to rotate to generate the rotating variable magnetic field signal, and the rotating variable magnetic field signal are transformed into two-phase electric signals with the phase difference of 90 degrees to and are transmitted to the microcontroller; and the counting mode is accurate.

Description

technical field [0001] The invention relates to the technical field of counting devices, in particular to an electronic digital display meter and a ram blowout preventer. Background technique [0002] In the field of oil and gas development, for the safety of drilling, ram blowout preventers are usually installed at the wellhead. Due to the many and complex uncertain factors in the formation, each drilling operation has the possibility of blowout, which has a great impact on well control. Technology and well control equipment put forward higher requirements. As the most important well control equipment, the blowout preventer needs to be activated quickly to shut down the well once overflow, well kick, blowout and other emergencies occur during drilling operations. , the reasonable design of the blowout preventer plays a very important role in ensuring the smooth progress of drilling operations and personal safety. The ram blowout preventer is mainly used in oil testing, wor...
