[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0019] like Figure 1-2 As shown, the sand mill barrel 1 includes a double-layer structure. The outer wall of the sand mill barrel 1 is provided with a water inlet 2 and a water outlet 3. One end of the sand mill barrel 1 is detachably fixed with a fixing mechanism 4 to prevent axial movement of the inner barrel 101 during water testing. The water inlet 2 is mounted with a detection mechanism 5, which is used to detect the sealing of the outer barrel 102. The detection mechanism 5 includes a first three-way valve 501, a second three-way valve 502, a first ball valve 503, a third three-way valve 504, a pressure regulating valve 505, and an air pipe 506, which are sequentially installed on the water inlet 2. The first three-way valve 501 is also connected to a water injection valve 6, the second three-way valve 502 is also connected to a pressure gauge 7, and the third three-way valve 504 is also connected to a second ball valve 8. The water outlet 3 is provided with a drain valve 9. The addition of the drain valve 9 ensures that when the pressure of the sand mill barrel 1 is high, the cooling water of the sand mill barrel 1 can be discharged in time to avoid damage to the workpiece.
[0020] Furthermore, the sand mill barrel 1 includes an inner barrel 101 and an outer barrel 102 , and the fixing mechanism 4 includes a wooden block 401 and a cushion block 402 detachably fixed to the outer barrel 102 , and the cushion block 402 is used in conjunction with the inner barrel 101 .
[0021] Furthermore, two fixing mechanisms 4 are symmetrically provided at both ends of the sand mill barrel 1 .
[0022] Working principle: Operation method: 1. Install the corresponding first tee 501, second tee 502, first ball valve 503, third tee 504, pressure regulating valve 505 and air pipe 506 at the water inlet 2 of the sand mill cylinder 1. Install the water injection valve 6 on the first tee 501, install the pressure gauge 7 on the second tee 502, and install the second ball valve 8 on the third tee 504;
[0023] 2. Install a drain valve 9 of corresponding size chuck at the water outlet 3 of the sand mill cylinder 1;
[0024] 3. Fix a wooden block 401 at the flange threaded hole of the outer cylinder 102 at both ends of the sand mill cylinder 1, and insert a wooden pad 402 between the wooden block 401 and the inner cylinder 101 to prevent the inner cylinder 101 from axial movement during water testing;
[0025] 4. Before water testing, close the first ball valve 503 and open the drain valve 9 of the water inlet and outlet 3 (Note: the drain valve 9 of the water outlet 3 must be opened to prevent damage to the outer cylinder 102); inject water into the cooling chamber through the water injection valve 6. After the cooling chamber is filled with water (water overflows from the drain valve 9 of the water outlet 3), close the drain valve 9 of the water outlet 3.
[0026] 5. Water test: Ventilate the cooling chamber through the air pipe 506, first adjust the pressure regulating valve to 3 bar, and then open the first ball valve 503. When the pressure gauge 7 shows 3 bar, close the first ball valve 503 and perform a sealing test on the cooling chamber (test water pressure 3 to 3.5 bar, time not less than 1 hour).
[0027] 6. Detect leakage. Brush foam water on all weld surfaces with a brush to observe whether there is leakage. Before observing the inner cylinder 101, wipe its surface dry and then observe.
[0028] 7. After 1 hour, check whether the air pressure changes. If the set pressure value changes by more than 2% (there is leakage in the inner tube 101 or penetration in the outer tube, or both), the pressure test fails. If the pressure value changes by no more than 2% (there is no leakage in the inner tube 101 and the outer tube 102), the pressure test passes.
