Description
Affiliated technical field
The utility model relates to a kind of performance detection apparatus of specialized equipment, is a kind of performance detection apparatus of pressure conditioning equipment specifically.
Background technology
Existing pressure regulator static characteristic checkout equipment comprises gas-holder, glass rotameter group, some tensimeters and some ball valves, and they are cascaded by pressure pipeline.This checkout equipment is configured to: the exit of gas-holder is provided with the gas-holder delivery gauge, every glass rotameter two ends are respectively equipped with flowmeter import butterfly valve and flowmeter exit butterfly valve, be respectively equipped with flowmeter inlet pressure gauge and flowmeter delivery gauge at the two ends of glass rotameter group, be provided with vent valve in glass rotameter group exit, be provided with the pressure regulator delivery gauge in tested pressure regulator exit, between gas-holder and glass rotameter group, be provided with first ball valve, between glass rotameter group and tested pressure regulator, be provided with second ball valve, between tested pressure regulator and gas exhaust duct, be provided with the 3rd ball valve.
The method of operating of this checkout equipment is: the first step, set the pressure regulator closing presure.If the reading of flowmeter inlet pressure gauge is P1, the reading of flowmeter delivery gauge is P1 ', and the pressure regulator top hole pressure is P2, and the pressure regulator closing presure is P
bAt first open first ball valve, when maximum inlet force value that P1 requires a little more than pressure regulator, close first ball valve.Open flowmeter import butterfly valve and flowmeter exit butterfly valve then, when if P1 ' reaches the maximum inlet force value of pressure regulator requirement, regulate the pressure regulator set screw, make 1.25 times of pressure regulator top hole pressure meter reading Da Eding top hole pressure, the static pressure that this moment, the pressure regulator delivery gauge showed is P
bWhen P1 is lower than the maximum inlet force value of pressure regulator requirement, adjust P1 by opening first ball valve, when P1 is higher than the maximum inlet force value of pressure regulator requirement, adjust P1 by opening vent valve, make P1 reach the maximum inlet force value of pressure regulator requirement, and then regulate the pressure regulator set screw, set P
bSecond step, the detection of flow.At first a people is little opens first ball valve, makes the pressure regulator intake pressure value of P1 a little more than customer requirements, and another people finely tunes vent valve, makes P1 ' just in time reach the intake pressure value of customer requirements, and the 3rd people slowly opens the 3rd ball valve simultaneously.Because pressure regulator outlet at this moment guarantees that P1 ' is stabilized on the numerical value of requirement in the exhaust that does not stop so need continue to open first ball valve make-up gas.And this moment because P1 and P2 are stable as yet, just need to adjust flowmeter import butterfly valve and flowmeter exit butterfly valve before and after the glass rotameter, make the glass rotors of flowmeter steady gradually, when P1 and P2 reach requirement numerical value, read glass rotameter numerical value.By GB16802-97 pressure regulator is carried out Performance Detection at last.
The defective of this checkout equipment is: the people who needs when 1, detecting the pressure regulator performance is many.At least need three people operation when detecting the pressure regulator performance, a people controls first ball valve, and a people controls the vent valve behind glass rotameter front and back butterfly valve and the flowmeter, and another people controls the 3rd ball valve.2, the time that detect to need long, and the data that detect are difficult for accurately, source of the gas is wasted bigger.Because three people are adjusting simultaneously when detecting, be difficult to reach tacit agreement and make tested pressure regulator import and export pressure accurately reach required numerical value simultaneously, so detection time is longer, data are difficult for accurately, obviously will waste a lot of sources of the gas when detecting big flow pressure regulator.3, because the checkout equipment gauge tap is and is directly installed on ducted big valve, operating difficulties during detection is difficult for fine setting.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of pressure stability, and the reading standard detects the pressure regulator static characteristic checkout equipment that the time spent is short, gas consumption is few, operating personnel are few.
Technical solution of the present utility model is: the pressure regulator static characteristic checkout equipment comprises gas-holder, flowmeter, some ball valves and plurality of conduits, it is characterized in that: it also comprises one-level pneumatic valve and secondary pneumatic valve, and they are formed by connecting with bolt successively by the order of gas-holder, ball valve, one-level pneumatic valve, pipeline, ball valve, pipeline, flowmeter, pipeline, ball valve, the tested pressure regulator of pipeline, pipeline, secondary pneumatic valve, gas exhaust duct.The one-level pneumatic valve is made up of main body and pilot valve two parts, and both are connected with signal pipe, fast joint.The secondary pneumatic valve is made up of main body, needle valve and vent valve, and they are connected with signal pipe, fast joint.In the gas-holder exit, one-level pneumatic valve exit, flowmeter exit, tested pressure regulator exit respectively be provided with a tensimeter respectively, the needle valve and the vent valve of each tensimeter, one-level pneumatic valve pilot valve, secondary pneumatic valve are arranged on the control and monitor console, and they are connected on the relevant position of checkout equipment by signal pipe, fast joint respectively.
Using method of the present utility model is: the first step, set the pressure regulator closing presure.1, after gas-holder pumps enough air in, slowly opens the ball valve on the trunk line successively.2, the set screw on the adjusting one-level pneumatic valve pilot valve, the reading on one-level pneumatic valve outlet pressure table equals the maximum inlet force value that tested pressure regulator requires.3, regulate the set screw of tested pressure regulator, observe the pressure gauge reading in tested pressure regulator exit, 1.25 times of the specified top hole pressure of setting until the user, the static pressure that this moment, the pressure regulator delivery gauge showed is the pressure regulator closing presure.Second step, the detection of flow.1, closes needle valve, slowly open vent valve, pressure gauge reading until tested pressure regulator exit is specified top hole pressure value, close vent valve immediately, needle valve, vent valve are finely tuned, pressure gauge reading until tested pressure regulator exit is stabilized on the specified top hole pressure value of setting, simultaneously the meter readings under this operating mode of observed and recorded.2, by GB16802-97 pressure regulator is carried out Performance Detection.
Advantage of the present utility model is: therefore 1,, be convenient to observe and operation because all tensimeters and gauge tap on this checkout equipment all are arranged on the control and monitor console, only need a people to stand in platform before operation get final product.2, because one-level pneumatic valve and secondary pneumatic valve are equivalent to voltage stabilizer, so control pressure before and after the tested pressure regulator respectively by one-level pneumatic valve and secondary pneumatic valve, the stream pressure quite stable, the pressure regulator performance data of measuring is accurate, time spent is few, saves source of the gas.3, be connected to P cock on the control and monitor console because the checkout equipment gauge tap is by signal pipe, fast joint, therefore operate light, accurate, highly sensitive.
