Abstract
The invention discloses a soft sensing head and a pressure gage antifreezing device with pressure zero adjustment. The main body of a cross fan (5), a pipeline connector (1) installed on the main body of the cross fan (5), a pressure gage switch (2), an oil filling port (3), a zero adjustment part (4) and a soft sensing head (6) form a sealed containing cavity; and the sealed containing cavity is filled with antifreezing liquid for transferring pressure. The working pressure of detected liquid is obtained indirectly by detecting the pressure of the antifreezing liquid.
Description
Technical field the present invention relates to be operated under (field) cold environment, a kind of device of keep-up pressure table or pressure sensor operate as normal.
Background technology is in order to grasp the duty of every mouthful of oil well and water injection well, just need to monitor in real time the operating pressure of oil well and water injection well, because water can freeze in subzero, high moisture crude oil also the situation of freezing can occur, and this has just influenced the collection of winter to oil well and water injection well pressure data.
Why goal of the invention pressure meter or pressure sensor run into icing problem, be because one section immobilising fluid to be measured that easily freezes is arranged between from the survey mark to the detecting element, if this section space is come filling with antifreeze liquid and the antifreezing liquid of filling can not run off, just can solve the open-air in the winter time problem of freezing of pressure meter or pressure sensor.
Summary of the invention the present invention is to use the antifreezing liquid that is sealed to transmit the operating pressure of fluid to be measured.This device is made up of pipeline connector (1), pressure meter switch (2), oil filler (3), adjustment member at zero point (4), four-way (5) and soft inductive head (6) and soft inductive head protection duricrust (7).The body of four-way (5) has constituted an airtight cavity volume with the pipeline connector (1), pressure meter switch (2), oil filler (3), adjustment member at zero point (4) and the soft inductive head (6) that are installed in above it, has been full of the antifreezing liquid that transmits pressure in airtight cavity volume.By detecting the pressure of antifreezing liquid, obtain the operating pressure of fluid to be measured indirectly.Primary structure of the present invention is: pipeline connector (1) and soft inductive head (6) are installed in the bottom of four-way (5); Oil filler (3) is installed in the top of four-way (5); Pressure meter switch (2) and adjustment member at zero point (4) are installed in the right and left of four-way (5) respectively.Device of the present invention is in order to respond to the actual pressure of fluid to be measured exactly, the special soft inductive head (6) that induction fluid to be measured pressure is installed in the centre of pipeline connector (1), soft inductive head (6) is to be made by the tubulose oil resistant soft-medium of the tubulose oil resistant rubber of end socket or other end socket.Work stably in a long term in order to make soft inductive head (6); in the outside of soft inductive head (6) soft inductive head protection duricrust (7) is installed, the elongated slot that has four wide millimeter of symmetry on soft inductive head protection duricrust (7) is used to transmit the operating pressure of fluid to be measured.
The invention effect is because the present invention has adopted antifreezing liquid to transmit the operating pressure of fluid to be measured, the deformation element mounting portion of survey mark from pressure meter or pressure sensor extended to the mobile fluid to be measured, restrain according to the Bath fastening: be added in the pressure on the liquid in the closed container, can be by liquid to all directions transmission.Therefore, the defective that device of the present invention has been avoided the immobilising fluid to be measured that easily freezes in pressure meter or the pressure sensor has realized the effect that pressure meter or pressure sensor are antifreeze.
Inventive embodiment accompanying drawing 1 is a structural representation of the present invention, and the present invention mainly is made up of 9 kinds of elements, and accompanying drawing 1 has been drawn the particular location between them.
The present invention is to be the center with four-way (5).Pipeline connector (1) is installed in the bottom of four-way (5); Oil filler (3) is installed in the top of four-way (5); Pressure meter switch (2) and adjustment member at zero point (4) are installed in the right and left of four-way (5) respectively.The soft inductive head (6) that transmits pressure is installed in the centre of pipeline connector (1) simultaneously.Soft inductive head protection duricrust (7) is installed in the outside of soft inductive head (6).Pipeline connector (1) links together by the pipeline of welding with the present invention and fluid to be measured, big nut (8) will guarantee that device of the present invention is installed in the pipeline any direction of fluid to be measured, and " O " type circle (9) seals the pipeline of fluid to be measured and the movable position between the present invention.In addition, between soft inductive head (6) and the four-way (5), between pressure meter switch (2) and the four-way (5), between oil filler (3) and the four-way (5), between adjustment member at zero point (4) and the four-way (5) " O " type circle is installed all.This makes the present invention form an airtight cavity volume with respect to the outside, has been full of the antifreezing liquid that transmits pressure in cavity volume.
The tubulose oil resistant rubber of soft inductive head (6) or other tubulose oil resistant soft-medium protect the elongated slot of a millimeter of last four symmetries of duricrust (7) to contact with fluid to be measured by opening at soft inductive head; when the pressure of ducted fluid to be measured changes; inside and outside formation pressure differential at soft inductive head (6); this pressure differential produces a power; make tubulose oil resistant rubber or other tubulose oil resistant soft-medium of soft inductive head (6) produce deformation; compressing is filled in the antifreezing liquid in the soft inductive head (6); make antifreezing liquid produce corresponding pressure, the pressure of fluid to be measured just is delivered on pressure meter or the pressure sensor by this process.
Adjustment member at zero point (4) is mainly used to add or when replenishing antifreezing liquid, by precession and back-out the antifreezing liquid in the airtight cavity volume is flowed, and plays the effect of deaeration.
