Example Embodiment
[0020] Example 1
[0021] The constant temperature and constant pressure filling method for the working fluid of the bellows for the thermostat is:
[0022] Step 1. Put the bellows into the incubator, clamp the capillary of the bellows on the clamp of the bellows, and adjust the temperature in the incubator to 40℃;
[0023] Step 2: Connect the capillary tube of the bellows with the vacuum pump, start the vacuum pump to vacuum the inside of the bellows, the vacuum degree is 30Pa;
[0024] Step 3. After vacuuming, cut off the connection path between the capillary tube of the bellows and the vacuum pump, and connect the capillary tube with the gas tank through the pressure regulator, and adjust the inflation pressure of the gas tank to 0.4MPa to inflate the bellows by the pressure regulator. The inflation ends when the pressure is balanced;
[0025] Step 4: Seal the diaphragm to complete the filling of the diaphragm.
Example Embodiment
[0026] Example 2
[0027] The constant temperature and constant pressure filling method for the working fluid of the bellows for the thermostat is:
[0028] Step 1. Put the bellows into the incubator, clamp the capillary of the bellows on the clamp of the bellows, and adjust the temperature in the incubator to 60℃;
[0029] Step 2: Connect the capillary tube of the bellows with the vacuum pump, start the vacuum pump to vacuum the inside of the bellows, the vacuum degree is 50Pa;
[0030] Step 3. After vacuuming, cut off the connection path between the capillary tube of the bellows and the vacuum pump, and connect the capillary tube with the air tank through the pressure regulator, and adjust the inflation pressure of the air tank to 0.6MPa to inflate the bellows by the pressure regulator. The inflation ends when the pressure is balanced;
[0031] Step 4: Seal the diaphragm to complete the filling of the diaphragm.
Example Embodiment
[0032] Example 3
[0033] The constant temperature and constant pressure filling method for the working fluid of the bellows for the thermostat is:
[0034] Step 1. Put the bellows into the incubator, clamp the capillary of the bellows on the clamp of the bellows, and adjust the temperature in the incubator to 50℃;
[0035] Step 2: Connect the capillary of the bellows with the vacuum pump, start the vacuum pump to vacuum the inside of the bellows, the vacuum degree is 40Pa;
[0036] Step 3. After vacuuming, cut off the connection path between the capillary tube of the bellows and the vacuum pump, and connect the capillary tube with the air tank through the pressure regulator, and adjust the inflation pressure of the air tank to 0.5MPa to inflate the bellows by the pressure regulator. The inflation ends when the pressure is balanced;
[0037] Step 4: Seal the diaphragm to complete the filling of the diaphragm.
