Background technology
Valve applications is in the unlatching of the various devices such as oil, chemical industry, electric power, iron and steel, rock gas, water conservancy, closedown and regulable control, and realize controlling just must on valve supporting manual, pneumatic, electronic, the drive unit such as surge, and the drive unit of concrete supporting much specifications just depends on the size of this valve torque, therefore, the mensuration of valve torque just seems extremely important.
In order to measure the moment of torsion of a deck valve door, the main dial torque wrench that adopts carries out, as mechanical torque spanner, digital dial torque wrench etc. at present.But the measurement range of dial torque wrench is limited, the torque value that generally can effectively measure is at below 2000Nm, and the torque value of the heavy caliber industrial valve of practical application may up to more than 300000Nm, and dial torque wrench can not meet practical application needs far away.Therefore, many units are also at effort research and development high pulling torque proving installation, but up to the present, the maximum torque of the domestic actual torque sensor that can demarcate is only 50000Nm, still cannot meet the actual demand of industrial development.And the comparatively high pulling torque proving installation of current studies in China and exploitation can only be tested under valve is not with pressure condition, the torque value under its torque value tested out and duty with pressure also exists maximum error.
Therefore, the drive unit that comparatively high pulling torque, particularly high pulling torque, large bore valves are supporting at present also exists in the superfluous or practical application of driving torque cannot the situation of driver's valve door switch action, has very big potential safety hazard to the application of various device.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existed to overcome prior art, and a kind of valve high pulling torque Analytical system is provided, it can carry out in real time heavy caliber, high pulling torque valve under working pressure conditions, facilitate, accurate and effective torque rating and record, thus provide valid data support for its supporting suitable drive unit, to eliminate the potential safety hazard in practical application.
For achieving the above object, the technical solution of the utility model includes drive unit, torque sensor, planetary gear mechanism and outlet terminal, the switch drive that described drive unit is used for tested valve provides driving force, described torque sensor is connected with the clutch end of drive unit, the power intake of described planetary gear mechanism is connected with torque sensor, and the clutch end of this planetary gear mechanism drives with the valve rod of tested valve and is connected;
Described torque sensor is used for the mensuration of drive unit input torque when tested valve door switch drives;
The Power output value of described planetary gear mechanism is greater than power input value, and it is for amplifying drive unit output torque, and Direct driver valve carries out switch motion;
Described outlet terminal, is connected to the output terminal of torque sensor, for measuring the output of the data of moment of torsion to torque sensor.
Further setting also includes pressure test device, and this pressure test device is used for the pressure medium input specified tested valve.
Further setting is that drive unit also includes propulsion system and is connected to the deceleration output device of propulsion system output terminal.
Further setting is described propulsion system is motor.
Further setting is that planetary gear mechanism includes sun gear, planet carrier, engaged wheel and gear ring, sun gear is wherein driving link, and it is connected with torque sensor output terminal, and gear ring is Passive part, its output terminal is directly connected with the valve rod of tested valve, and planet carrier is fixing.
Adopt technique scheme, first tested valve is installed among pressure test device, and according to the working pressure of specifying, specified value is applied pressure to tested valve internal, then planetary gear mechanism is directly carried out installing and fixing with tested valve, at this moment, drive unit is started working, by planetary gear mechanism, tested valve is driven simultaneously, until open tested valve, test torque value is outputted to outlet terminal by torque sensor automatically that be connected between drive unit and planetary gear mechanism, first test result is carried out record and is automatically drawn torque curve figure by outlet terminal, automatically calculate according to the planetary gear mechanism amplification coefficient of accurate calibration simultaneously, outlet terminal will calculate maximum unlatching moment of torsion and the change in torque of valve practical measurement automatically, and record is carried out to result of calculation and automatically draws valve torque curve map, because planetary mechanical efficiency is high and stable, thus its amplification coefficient does not need too large, general amplification coefficient is can meet within 10, and the mensuration of this amplification coefficient does not need very high pulling torque sensor to implement, therefore, if carry out supporting with the planetary gear mechanism of the 50000Nm torque sensor can demarcated at present and 10 times of amplification coefficients, accurate and effectively can measure the valve torque within 500000Nm, thus provide and provide powerful support for for heavy caliber, drive unit that high pulling torque valve matched is suitable, eliminate the potential safety hazard in practical application.
