Water stop structure of water pump outlet pipe

Abstract

The invention discloses a water stopping structure of a water outlet pipe of a water pump. The water stopping structure of the water outlet pipe of the water pump comprises a wall, the water outlet pipe penetrating through the wall, and a water stopping ring which is embedded in the wall and welded on the outer wall of the water outlet pipe. An annular L-shaped water stopping belt is arranged on the connecting portion of the water outlet pipe and the outer side of the wall body, a circular ring of the water stopping belt is arranged on the outer wall of the water outlet pipe in a sleeved mode, at the two ends of an L shape of the water stopping belt, one end of the L-shaped water stopping belt is fixed on the wall, and the other end of the L-shaped water stopping belt is fixed on the outer wall of the water outlet pipe. The water stopping structure of the water outlet pipe of the water pump overcomes the defects that water leakage can happen easily in a traditional water stopping structure, and maintaining and repairing are not easy. In the practical application process, due to the effect of outer water pressure, stopping water is made to be in a squeezing state, so that the water stopping effect is achieved effectively, even though the wall and the water outlet pipe are deformed and dislocated seriously, the strong tensile deformation capacity of the water stopping belt can meet the application requirement, and later repairing and replacing are simpler, more convenient and easier to implement compared with a traditional mode.

Description

technical field [0001] The invention relates to a water stop structure for a water pump outlet pipe, which is mainly used for water stop between the water pump outlet pipe and the wall. Background technique [0002] In the prior art, the traditional water-stop treatment method between the water outlet pipe of the water pump and the wall is as follows: sometimes a water-stop glue strip is wrapped around the contact surface of the water outlet pipe and the wall, and the joints are filled with asphalt hemp ropes; Some use a water stop ring welded on the steel pipe, and then directly pour it into the concrete, which is a rigid connection; some are only wrapped with asphalt hemp rope because the external water pressure is small or the outlet pipe is above the water level. The above method has been used in many pumping stations, but in the actual application process, the pumping station has experienced water leakage of different degrees. There are gaps, water-stops and voids, and...

AI Technical Summary

Problems solved by technology

The above method is used in many pumping stations, but in the actual application process, the pumping station has different degrees of water leakage. The main reason is that the vibration generated during the operation of the water pump causes the gap between the water stop of the outlet pipe and the concrete wall. There are gaps, water-stop voids, and the filling of asphalt hemp rope is not dense enough, and partial defects and dislocations of water-stop rubber strips, etc.

In addition, the quality of the waterproof rubber strip also affects the durability of use. Once the rubber ages, it is difficult to replace it, and the water leakage will become more serious.
