Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1 and 2, there is shown a reservoir vent valve replacement assisting apparatus comprising: the pipe valve 4 is installed to the one end of delivery pipe 1, and the one end welding of delivery pipe 1 has guide bar 13, and the sliding is provided with closing cap 2 on the guide bar 13, and guide bar 13 is to the reciprocating of closing cap 2 and is guided, and the lower extreme of closing cap 2 is provided with sealed pad 22, and sealed pad 22 can carry out the shutoff to inlet port 11 through sealed pad 22 when closing cap 2 cup joints down on delivery pipe 1, and sealed pad 22 meets with delivery pipe 1.

The inside of the sealing cover 2 is provided with a buoyancy cavity 21, and the inner side of the buoyancy cavity 21 is provided with a water pump 3.

The delivery port of water pump 3 is connected with outer calandria 31, the one end of outer calandria 31 is located the buoyancy chamber 21 outside, the water inlet of water pump 3 is connected with three way solenoid valve 32, be connected with the water suction pipe 33 on the interface of three way solenoid valve 32, when needing to change tube valve 4, water pump 3 operates three way solenoid valve 32 and opens and inhale the buoyancy chamber 21 with water through water suction pipe 33, after the water intaking in the buoyancy chamber 21, closing cap 2 is sunken along guide tube 13 to carry out shutoff to discharge tube 1, then can carry out tube valve 4 and change, when discharging, water pump 3 operation is through three way solenoid valve 32 control water pump 3 with the buoyancy chamber 21 in water discharge through outer calandria 31, the air intake in the buoyancy chamber 21, closing cap 2 upwards moves along guide rod 13 and breaks away from inlet 11, then can discharge water in the reservoir through tube valve 4.
