With reference to Fig. 8 and Fig. 9, using following methods to former pipeline and new pipeline anti-impact force strength test, gained compares number
According to as shown in table 1.
Specific test method are as follows: apply a fixed constant force in the direction x, y, xy, be 25N in this example, then release should suddenly
Power tests the stress of measuring point 1 and measuring point 2.
Table 1
In the case where applying same power, the new curved position of pipeline assembly stress position stress value more curved than former pipeline assembly stress is small,
Thus pipeline assembly scheme new compared with former pipeline assembly scheme has more preferably impact strength.
It to expand the center of circle of valve coil top surface as coordinate origin, while being force part；AD edge direction is the direction x, the side DC
Direction is the direction y, and AC edge direction is the direction xy.
Test process is as follows:
1. point position selects: a curved position nearest close to welded pipe is selected, at the curved position excurvation back side (measuring point 1) and outside
Curved side (measuring point 2) pastes strain gauge.Select measuring point 1 and the reason of measuring point 2 to be easy to happen out at solder joint when product falls
Split, that is, in Fig. 9 right side that root weld nipple, for comparison two schemes solder joint at stress intensity, nearest apart from solder joint
Curved position paste strain gauge, carry out stress test, judge scheme superiority and inferiority is gone by stress test result.
2. acquiring signal using stress test equipment；
3. slowly being pulled using tensiometer in the direction x at coil of electronic expansion valve, until tensiometer reaches specified force value
Size, this example are 25N, then discharge the power in passing, and electric expansion valve pipeline assembly can generate transient vibration, until vibration decaying
It is sufficiently small after, stop signal acquisition.The pulling force in the direction x is the temporary impact generated in order to simulate left rib, when right rib falls.This
The method of the abrupt release power in example are as follows: cover one thin cotton cord on expansion valve coil, tensiometer catches on cotton cord, works as tensiometer
Reach specified force value, quick shearing cotton cord.
Likewise, wherein the pulling force in the direction y is for mould according to the stress value of step 2 and 3 the acquisition directions y and the direction xy
The temporary impact intending preceding rib, generating when rear rib falls, the pulling force in the direction xy be in order to simulate left-front corner, generation when right relief angle is fallen
Temporary impact.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
