The water pipe and the water inlet pipe of the water pump, the water suction pipe extends from the cylinder to the upper part of the cylinder, the upper part of the cylinder is welded with the head, and an overflow pipe is installed on the head, the water injection pipe is set on the cylinder, and the overflow Valves are installed on the pipe and the water injection pipe. After the pipeline is connected and installed, first open the valves of the water injection pipe and the overflow pipe, and inject water until the overflow pipe overflows, then close the valves of the overflow pipe and the water injection pipe to make them in a sealed state. When starting the water pump, the water pump first The water stored in the pumping cylinder makes the liquid level drop to a certain negative pressure, so that the negative pressure forces the suction pipe to fill with water, thus ensuring the normal operation of the water pump.
本实用新型的有效益果是，可安装在水泵进水管上用于实现吸入式工作时的负压引水，具有结构设计合理、使用安装方便、运行可靠、启动快、有利于节约用电等特点，可适用于水泵安装不能实现自灌式工作而需采取吸入式引水的场合。The beneficial effect of the utility model is that it can be installed on the water inlet pipe of the water pump to realize the negative pressure water diversion during the suction operation, and has the characteristics of reasonable structure design, convenient use and installation, reliable operation, fast start-up, and saving electricity. , can be applied to the occasions where the water pump installation cannot realize self-priming work and needs to adopt suction water diversion.

5、具体实施方式5. Specific implementation
下面就附图1对本实用新型的负压罐作以下详细地说明。Below with regard to accompanying drawing 1 negative pressure tank of the present utility model is described in detail below.
如附图1所示，本实用新型的负压罐，是由筒体(2)、吸水管(1)、接水泵进水管(7)、注水管(6)、溢流管(4)及阀门(5)组成，筒体(2)下部两侧分别装设有吸水管(1)和接水泵进水管(7)，吸水管(1)在筒体(2)内伸到筒体(2)上部，筒体(2)上部与封头(3)焊制，并在封头(3)上装设有溢流管(4)，注水管(6)设在筒体(2)上，且在溢流管(4)和注水管(6)上均装设有阀门(5)。管道连接安装后，先打开注水管(6)和溢流管(4)的阀门(5)，并注水到溢流管(4)溢水为止，再关闭溢流管(4)和注水管(6)的阀门，使之呈封密状态，当启动水泵时，水泵先抽筒体(2)内的存水，使其液面下降至一定负压，由此负压迫使吸水管(1)上水，从而保证了水泵的正常运行。吸水管(1)伸入筒体(2)内上部的作用是为了防止因水泵停止运行后的存水从吸水管(1)流出造成负压破坏、水泵空转而吸不上水等现象。As shown in accompanying drawing 1, the negative pressure tank of the present utility model is made of cylinder body (2), suction pipe (1), water pump inlet pipe (7), water injection pipe (6), overflow pipe (4) and The valve (5) is composed of a water suction pipe (1) and a water pump inlet pipe (7) respectively installed on both sides of the lower part of the cylinder body (2), and the water suction pipe (1) extends from the cylinder body (2) to the cylinder body (2 ), the upper part of the cylinder (2) is welded with the head (3), and the overflow pipe (4) is installed on the head (3), and the water injection pipe (6) is arranged on the cylinder (2), and A valve (5) is installed on the overflow pipe (4) and the water injection pipe (6). After the pipeline is connected and installed, first open the valve (5) of the water injection pipe (6) and the overflow pipe (4), and inject water until the overflow pipe (4) overflows, then close the overflow pipe (4) and the water injection pipe (6) ) valve, so that it is in a sealed state. When the water pump is started, the water pump pumps the water stored in the cylinder (2) first, so that the liquid level drops to a certain negative pressure, and the negative pressure forces the suction pipe (1) to water, thus ensuring the normal operation of the pump. The function of the water suction pipe (1) extending into the inner upper part of the cylinder body (2) is to prevent negative pressure damage caused by the water storage after the pump stops running out of the water suction pipe (1), and the phenomenon that the water pump cannot absorb water due to idling.
