Abstract
The utility model discloses a spanner with a torsion value accurately measured. The spanner with the torsion value accurately measured is extremely suitable for fastening objects with torsion limiting such as fastening a packing box of a well mouth of an oil well of oil industry and adjusting a degree of tightness of a belt of a pumping unit, the normal production of the pumping unit can be ensured, and energy consumption is effectively reduced. The spanner with the torsion value accurately measured comprises a body and a handle which are connected through a shaft pin, and a torsion detecting device is installed in the body. The torsion detecting device comprises a pressure gage and a hydraulic pressure sensor, applied force on the handle is reflected on the pressure gage through the hydraulic pressure sensor, and a torsion applied value on the pressure gage is converted and obtained through a conversion table on a conversion scaleplate. Fastened objects with torsion limiting can be effectively protected, and negative effects due to the fact that the applied torsion is oversize or undersize are avoided. If the spanner with the torsion value accurately measured is used for fastening the packing box, the problem of blindness of fastening of the packing box by a pipe wrench at present is solved, the shortcoming of an existing torsion wrench is overcome, the service life of packing is prolonged, and energy consumption is reduced.
Description
Technical field
The utility model relates to the mechanical fasteners instrument, and a kind of moment of torsion measured value spanner accurately particularly is fit to be fastened with the object of torque limited, such as the packing box of fastening petroleum industry well mouth of oil well very much
, Adjust elasticity of belt of oil pumping machine etc., can normally produce to guarantee oil pumper, and can effectively reduce energy consumption.
Background technology
In the production well in present oil field, great majority adopt this modes of production of sucker rod pumpings.This mode of production is to rely on the down-hole roofbolt Surface power drive to be passed to the oil well pump of down-hole, and the top of down-hole roofbolt is called polished rod, needs to seal by packing between polished rod and the oil pipe.Because sealing is movable sealing, so packing just need to be often fastening, to reach the purpose of sealing.Fastening polished rod stuffing box uses pipe wrench usually in field produces, because specification and the user of pipe wrench cause packing box to cross pine or tension.Cross pine and then cause packing oil leakage in the short time, tension then causes packing to wear and tear greatly, polished rod generates heat energy consumption increase, the packing lost of life etc.Because the degree of tightness of packing box is determined by rule of thumb by the staff fully, so the packing box elasticity is random large, service life and energy-conservation can't being protected.A kind of torque wrench has appearred in the production scene at present, at the force side of boosting-rod even twisting moment dial, pointer one end is fixed on the body of spanner socket, and the other end is suspended in the top of moment of torsion dial, utilize the strain of boosting-rod, read the moment of torsion value of reading on the moment of torsion dial.This torque wrench can roughly predict the size of institute's application of force amount, avoids the excessive or too small consequence that causes of the packing application of force.But boosting-rod must be elongated, do not have concrete torque detecting apparatus, and the moment of torsion of surveying also is general result.Than using the fastening packing of pipe wrench, have certain effect, still can not guarantee well the packing application of force moderately, even, still can cause not bery accurate fastening consequence to packing.
Summary of the invention
The purpose of this utility model provides accurately spanner of a kind of moment of torsion measured value; overcome prior art and can't determine accurately that spanner applies the shortcoming of the size of strength to fastened object; the torque value that spanner can Accurate Determining be applied; the fastened object that protection has torque limited avoids applying the excessive or too small adverse consequences that causes of moment of torsion.
The present technique solution can reach above-mentioned purpose: a kind of moment of torsion measured value accurately spanner comprises that body is connected body and is connected pivot pin with handle and connects with handle, and torque detecting apparatus is housed in body.Torque detecting apparatus comprises Pressure gauge and hydrostatic sensor, and the power that applies on the handle is reflected on the Pressure gauge by hydrostatic sensor, and the moment of torsion value of applying on the Pressure gauge is converted by the conversion table on the conversion scale to be drawn.
The utlity model has following useful effect: can effectively protect the fastened object with torque limited, avoid applying the excessive or too small adverse consequences that causes of moment of torsion.As being used for fastening packing box, solved the blindness of the fastening packing of present pipe wrench, overcome the shortcoming of existing torque wrench, prolonged the service life of packing, reduced energy consumption.Main feature is embodied in:
1. compact conformation is easy to carry.This product all component all disposable assembling is finished, and only needs during on-the-spot the use opening set screw is just regulated and can be used.
2. firmly directly perceived.On this product Pressure gauge is housed, to firmly can reading from Pressure gauge intuitively of packing box, and reads the size of exerting oneself according to the moment on the conversion scale and conversion pressure table.
3, go for different nut diameters.By the opening set screw is regulated, namely can cooperate the nut of different sizes to use.
