Embodiment 1
[0023] The flow calibration tool of this embodiment includes a positioning ring 3-1, a pressing ring 3-7, a water inlet device 3-6 and a sealing gasket 3-4.
[0024] Among them, such as image 3 As shown, the surface of the product is an elliptical ring, and the positioning ring 3-1 is an elliptical ring (an annular structure consistent with the shape of the product), and an annular groove is processed on one end surface of the product, so that the positioning ring 3-1 includes an inner ring and an outer ring positioning ring 3-1 The outer circumferential surface of the inner ring is aligned with the inner circular surface of the product, and the outer ring is provided with through holes corresponding to the throttle holes on the product surface. The positioning ring 3-1 is provided with a symmetrical center positioning line or an angular position positioning line. During assembly, the positioning line on the positioning ring 3-1 is aligned with the corresponding symmetrical c...
Embodiment 2
[0028] On the basis of embodiment 1, it also includes a slider 3-5 which is adjustable in position in the through hole of the outer ring of the positioning ring 3-1, the slider can move left and right in the through hole, and the center of the slider 3-5 is provided with Threaded hole, water inlet device 3-6 is screwed in the threaded hole of adjustable slide block 3-5 center by thread, as Figure 4 shown. The position-adjustable slide block 3-5 is set in the through hole of the outer ring, which is used to solve the problem that the water inlet device 3-6 and the orifice cannot be aligned due to processing errors of tooling and products. In this embodiment, the slider 3-5 is a T-shaped structure, which can slide slightly in the T-shaped groove on the outer ring of the positioning ring. If the orifice deviates during processing, the water inlet device can also be aligned with the orifice.
