When in use, the upper end of the water inlet is connected to the tap water pipe, the water outlet is connected to the pressurized water pump, and the gas charging port is connected to the nitrogen cylinder through the pressure regulator. The reduced space will not generate negative pressure on the water pipe network and will not affect other users. However, when the pressure of the tap water pipe network drops or the water is cut off, the water stored in the pressure regulating tank will flow back to the tap water pipe network under the gas pressure in the nitrogen cylinder. The gas will also flow back into the water pipe network, affecting other water users and wasting the pressurized gas in the nitrogen cylinder.

发明内容Contents of the invention

本发明解决的技术问题是，解决现有技术存在的不足，提供一种当自来水管网压力下降或停水时，压力调节罐内的存水不会倒流回自来水管网，氮气瓶内的气体也不会倒流到自来水管网内，避免影响其他自来水用户，不会浪费氮气瓶内的有压气体的压力调节罐。The technical problem solved by the present invention is to solve the deficiencies in the prior art, and to provide a method that when the pressure of the tap water pipe network drops or the water is cut off, the water stored in the pressure regulating tank will not flow back into the tap water pipe network, and the gas in the nitrogen cylinder It will not flow back into the tap water pipe network, avoid affecting other tap water users, and will not waste the pressure regulating tank of the pressurized gas in the nitrogen cylinder.

本发明的技术方案是，一种压力调节罐，设有罐体，罐体顶部设有进水口、压力表和充气口，进水口内侧连接有进水管，进水管与压力调节罐腔体的底部连通，罐体底部设有出水口，主要结构特点是，进水口上设有倒流防止器。The technical solution of the present invention is a pressure regulating tank, which is provided with a tank body, and a water inlet, a pressure gauge and an air charging port are arranged on the top of the tank body, and a water inlet pipe is connected to the inner side of the water inlet, and the water inlet pipe is connected to the bottom of the cavity of the pressure regulating tank. Connected, there is a water outlet at the bottom of the tank, and the main structural feature is that a backflow preventer is provided on the water inlet.

本发明罐体一侧设有液位计，液位计上端与压力调节罐腔体的上部连通，液位计下端与压力调节罐腔体的底部连通。One side of the tank body of the present invention is provided with a liquid level gauge, the upper end of the liquid level gauge communicates with the upper part of the cavity of the pressure regulating tank, and the lower end of the liquid level gauge communicates with the bottom of the cavity of the pressure regulating tank.

本发明的有益效果是，由于进水口上设有倒流防止器，使用时进水口上的倒流防止器与自来水管连接，出水口与加压水泵连接，充气口经压力调节器与氮气瓶连接，当自来水管网压力下降或停水时，倒流防止器会隔断倒流的水或气体，防止压力调节罐内的存水倒流回自来水管网，氮气瓶内的气体也不会倒流到自来水管网内，避免影响其他自来水用户，也不会造成气体浪费。The beneficial effect of the present invention is that since the water inlet is provided with a backflow preventer, the backflow preventer on the water inlet is connected to the tap water pipe during use, the water outlet is connected to the pressurized water pump, and the air charging port is connected to the nitrogen cylinder through the pressure regulator. When the pressure of the water pipe network drops or the water is cut off, the backflow preventer will block the backflow of water or gas, preventing the water in the pressure regulating tank from flowing back into the water pipe network, and the gas in the nitrogen cylinder will not flow back into the water pipe network , to avoid affecting other tap water users, and will not cause gas waste.
