Description

Technical Field

An installation plate is fixedly installed on the back surface of the inner cavity of the metering box body. A heating component is arranged on the front surface of the installation plate. A heat exchanger is fixedly installed on the back surface of the inner cavity of the metering box body and above the installation plate. In the present invention, a liquid pump is provided to introduce the coolant inside the water tank into the first liquid guide pipe, and then the coolant is introduced into the interior of the heat exchanger through the first liquid guide pipe. Under the action of the heat pipe, the heat of the heating component is exported and transmitted to the heat exchanger. When the coolant passes through the heat exchanger, the heat of the heat exchanger is taken away. The coolant is introduced into the second liquid guide pipe from the left side of the heat exchanger, and then the coolant is introduced into the interior of the water tank through the second liquid guide pipe to form a cycle. At the same time, it solves the problem that the heat dissipation effect of the existing metering box is not good, resulting in residual heat remaining inside the metering box, which will damage the internal components of the metering box after a long time; In the above technology, through the cooperation of the coolant and the heat exchanger, the metering box is heat-dissipated.

At this time, the gas enters the first gas storage chamber 17 through the second exhaust pipe 16. When the support plate 5 pre-lifts the metering box body 4, the sliding support plate 5 moves downward with the metering box body 4. When the adjustment plate 8 moves to the trigger block 31, the trigger block 3 is squeezed with the cooperation of the beveled surface 32. 1. The fourth airbag 33 on one side of the trigger block 31 is squeezed, and the internal gas of the fourth airbag 33 is discharged to the inside of the fifth airbag 42 through the third exhaust pipe 38. The fifth airbag 42 expands and pushes the push rod 41 downward. When the push rod 41 moves to be flush with the groove 44, the stopper 43 is pulled backward by the sixth return spring 40.

At this time, the exhaust hole 45 coincides with the fourth receiving groove 46, and the gas inside the third airbag 24 is discharged to the second storage cavity 35 through the fourth receiving groove 46 under the abutment of the insertion rod 28. At this time, the insertion rod 28 is inserted into one of the through holes 27, completing the limit of the support plate 5; Then slide the slider 10 to make the clamping plate 11 fit with the fixing plate 1, and then screw the fixing bolt 12. The fixing of the metering box body 4 and the fixing plate 1 is achieved through the fixing bolt 12. When screwing, the fixing bolt 12 squeezes the sixth airbag 47, and the gas inside the sixth airbag 47 is discharged through the fourth exhaust pipe 48 to the seventh airbag 53.
