Water supply tank without tower

Abstract

The invention provides a technical scheme of a towerless water supply tank, which includes a bracket, and a tank body is installed above the bracket. One side is the water inlet pipe, and the other side is the water outlet pipe. The safety valve at the bottom of the tank is installed horizontally on the tee, the lower end of the tee is connected to the negative pressure valve, and the upper end of the tee is connected to the bottom of the tank. The bottom of the tank can also be installed in other parts. When the automatic water supply system fails and the pressure exceeds the set pressure, the safety valve will open and release the pressure automatically. When there is negative pressure, the negative pressure valve is opened to supply air to ensure that the tower-free water supply tank is not damaged.

Description

Technical field: [0001] The invention relates to an automatic water supply device, in particular to a towerless water supply tank. Background technique: [0002] In the prior art, the known water supply pressure tank is the patent No. 99220108.X utility model patent announced by the State Intellectual Property Office. The utility model discloses a tap water supply tank, which belongs to a device for water supply. It consists of a water supply tank 1, and its characteristic is that an electric automatic switch 2 is installed on the outlet pipe of the water supply tank 1, and a directional stop-back automatic switch water valve 3 is installed on its water inlet pipe, which is connected with the household water pump and the water outlet pipe. After being used in conjunction with the road, the water pump can be turned on and off automatically, so as to achieve automatic pumping and water use, so that domestic water can truly form tap water. However, the tap water supply tank of...

AI Technical Summary

Problems solved by technology

However, the tap water supply tank of this scheme, especially the safety valve without pressure relief, once the contact of the pressure relay is sintered and adhered does not trip, or the contact of the AC contactor is sintered and adhered without tripping, the water supply of the water pump cannot be stopped, and the water pressure continues to increase. , there will be a danger of explosion, which will cause life hazards to people, which is the deficiency of the existing technology
