Description

Pressure tank

Technical Field

The utility model belongs to the technical field of the overhead tank, refer in particular to an overhead tank.

Background

A pump is a machine for increasing the pressure of liquid or gas to make it transport flow, and is also a device for moving liquid, gas or special fluid medium, i.e. a machine for working fluid. At present traditional water pump, the right side sealing connection of its pump body has the motor, and the motor shaft of motor stretches into in the pump body and motor shaft end fixing has the impeller, the left side sealing connection of the pump body has the pump head, and the liquid outlet of pump head communicates with each other through the pipeline with the inlet of the pump body, has set gradually filter screen and check valve between the water inlet of pump head and the liquid outlet, and the upside opening of pump head passes through the pump cover seal, is equipped with the delivery port on the pump body. The traditional water pump can meet basic use requirements in daily use, but the water pump is short in service life and relatively low in working efficiency, and when water is suddenly interrupted, the functions of the water pump cannot be guaranteed, and the safety performance in use is low.

Chinese patent with patent number CN201720535533.9 provides a water pump with overhead tank, compensates the water pump through the overhead tank, lets the water pump last out water to current overhead tank is when producing, places the inner bag at the internal of jar earlier mostly, then presses the cover on the jar body through the mode of punching press again, forms a whole with the jar body with the cover.

However, after the pressure tank is used for a certain period of time, the inner container is damaged, but the inner container in the pressure tank cannot be taken out normally, and even if the tank body and the tank cover are separated forcibly, the tightness is greatly influenced, so that the pressure tank belongs to a disposable product, and the pressure tank cannot be repaired if the inner container is damaged. The market is that there is a pressure tank to pass through bolt fastening cover and jar body, but the fixed mode of bolt has a lot of not enough, for example: 1. because a plurality of bolts are needed for fixing, if the cross on the bolt is damaged, the installation or the disassembly is very inconvenient; 2. the phenomenon that the end part of the tank cover and the end part of the tank body cannot incline during installation, but when the tank cover and the tank body are installed through bolts, one bolt is not screwed down, and the sealing effect between the tank cover and the tank body can be influenced.
