Couple the present invention does further explanation below in conjunction with Fig. 1～3:
Like Fig. 1, shown in 2; First delivery pipe 11 and second delivery pipe 21 are different according to physical properties of fluids of carrying and temperature; Can adopt tubing such as welded still pipe, weldless steel tube or stainless-steel tube, but first delivery pipe 11 and second delivery pipe 21 must be taked material of the same race.
The refluence angle of fan-shaped mixed flow blade 13 also is that the angle between the axis of plate face and first delivery pipe 11 of mixed flow blade 13 need calculate according to the lower limit flow velocity of fluid; To guarantee that fluid reaches disturbed flow condition at pressure-measuring-point and temperature point place; When if fluid is water, the axis of the mixed flow blade 13 and first delivery pipe 11 also is that the angle of caliber center line is 25～45 °.
The aperture of pod apertures 14 and the size of percentage of perforation are relevant with rate of flow of fluid and viscosity, and when fluid was water, Φ 6mm～Φ 10mm was generally adopted in the aperture, and percentage of perforation is 20～35%.
Supporting flange 25 is used for this device is connected to the test unit, and as long as the specification of supporting flange 25 is identical with the specification of test machine group interface.
When this mixed flow type temperature, pressure sampler uses; The welding end surface 15 of first delivery pipe 11 and the welding end surface 24 of second delivery pipe 21 are welded; And first delivery pipe 11 that will weld together and second delivery pipe 21 be installed on the water system of handpiece Water Chilling Units proving installation through supporting flange 25, guarantee flow direction will be earlier through after the mixed flow section 10 again through the temperature, pressure measuring point on the sampling section 20.
As shown in Figure 2, when rate of flow of fluid is low, need to calculate the bee-line of the first spacing L1 and the second spacing L2, even with the fluid mixed flow that guarantees temperature, pressure measuring point place.Generalized case; If fluid is a water; When the caliber of first delivery pipe 11 and second delivery pipe 21 was DN100～DN300, the length of the first spacing L1 and the second spacing L2 was 300～650mm, and the length of the said first spacing L1 and the second spacing L2 can be got equal values or different value.
As shown in Figure 3, when fluid during through fan-shaped mixed flow blade 13, the angle of mixed flow blade 13 can make fluid produce rotation, thereby the fluids in first delivery pipe 11 are fully mixed, and has broken the original thermal stratification of fluid.Pod apertures 14 on the said mixed flow blade 13 mainly contains two effects, and the first reduces the resistance of mixed flow section 10, and it two is can produce jet when fluid during through pod apertures 14, thereby also can reach the purpose that fluid is mixed.Through the mixed flow effect of mixed flow section 10, when fluid arrives the temperature, pressure measuring point, can guarantee fluid through mixing fully, and then guarantee that the section temperature of fluid does not have layering, guaranteed the accuracy that temperature, pressure is measured.
