System to inject liquid from the bottom up

摘要

In a system for injecting liquid from the bottom up, the system includes an upper body 10 and a lower body 20. The upper body 10 includes a fixing part 12 and a lifting part 11 provided with an injection flow passage 15 in the middle. The fixing part 12 is fixedly installed on the inner bottom surface of the upper body 10. The elevating part 11 is installed in the fixing part 12 to enable vertical movement. The distribution hole 16 is formed in the inner wall of the elevating part 11. The injection flow passage 15 passes through the bottom of the upper body 10. The lower body 20 includes a stopper 21, a rigid cylindrical body 22, a foreign exchange expansion tube 24, and an inner ring expansion tube 26. The spring 25 is installed in the inner ring expansion and contraction tube 24. The rigid cylindrical body 22 is provided on the upper plate 24a to provide a passage. The inner ring expansion and contraction pipe 26 is installed in the foreign exchange expansion pipe 24 and penetrates the rigid cylindrical body 22. The lower plate 24b is provided with a support cylinder 23, the support cylinder 23 passes through the inner ring expansion and contraction pipe 26 and extends to the rigid cylinder body 22. The stopper 21 connected to the upper portion of the rigid cylindrical body 22 is fixedly installed on the upper portion of the supporting cylinder 23. The outer wall of the stopper 21 is formed on the inner wall of the upper part of the lifting part. The injection system can save cost and reduce the probability of burns without causing sprinkles or leaks.
