Technical field
The present invention relates to a kind of test threeway for pressure transducer.
Background technique
In each characteristic point of refrigeration system, the state of refrigeration agent determines by two parameters of temperature and pressure are common, thus need to gather the pressure and temperature value of each characteristic point of refrigeration system simultaneously and analyze, thus the coupling of whole refrigeration system is optimized.In conventional refrigeration system, during test refrigeration system characteristic point pressure, usually utilize three-way pipe that pressure gauge or pressure transducer are connected in refrigeration system.The main line of three-way pipe is connected in refrigeration system pipeline, identical with main line or close with the diameter of the vertical connected testing tube of main line, testing tube is connected on main line by welding or alternate manner, and the diameter of the connectivity part of the two is identical with the caliber of testing tube.
Test result shows, the three-way pipe of existing pressure gauge or pressure transducer, can cause the characteristic of refrigeration system to change, especially under compressor continuous operation condition, the pressure-enthalpy chart of refrigeration system changes a lot, cause the rising of refrigeration system evaporating temperature, condensing temperature to decline, thus cannot the original system features of correct measurement.
Summary of the invention
The present inventor is surprised to find that, when the size of the joint of connecting tube and testing tube is during much smaller than the caliber of testing tube, can effectively solve the effect of utilizing three-way pipe to connect the original refrigeration system characteristic of destruction causing, the operation of original refrigeration system is exerted an influence hardly.
The present invention is intended to solve at least to a certain extent one of technical problem in correlation technique.
For this reason, one object of the present invention is to propose a kind of test threeway for pressure transducer of simple in structure, good test effect.
The test threeway for pressure transducer according to the embodiment of the present invention, comprising: connecting tube, has the test aperture that connects described tube wall on the tube wall of described connecting tube; And testing tube, the lower end of described testing tube be connected with the periphery wall of described connecting tube and the inner circle wall of described testing tube around described test aperture.
According to the test threeway for pressure transducer of the embodiment of the present invention, on the tube wall of connecting tube, there is the test aperture that connects tube wall, after testing tube Bonding pressure sensor, the inductive probe of pressure transducer contacts with the periphery wall of connecting tube, the force value that detects refrigeration pipe by test aperture, measurement effect is good.
In addition, the test threeway for pressure transducer according to the above embodiment of the present invention can also have following additional technical characteristics:
According to an example of the present invention, the axis quadrature of the axis of described connecting tube and described testing tube.
According to an example of the present invention, the axis of described testing tube is through the center of described test aperture.
According to an example of the present invention, the aperture of described test aperture is 1mm-2mm.
According to an example of the present invention, described testing tube is welded on described connecting tube.
According to an example of the present invention, the caliber of described connecting tube is identical with the caliber of described testing tube.
Additional aspect of the present invention and advantage in the following description part provide, and part will become obviously from the following description, or recognize by practice of the present invention.
Accompanying drawing explanation
Fig. 1 is according to an embodiment of the invention for the schematic diagram of the test threeway of pressure transducer;
Fig. 2 is the plan view of Fig. 1.
Embodiment
