Problems solved by technology

[0002] At present, in the water supply system of high-rise buildings in cities and towns, water outlet pools or water storage tanks are generally used to store water, which are bulky, expensive, and easy to cause secondary pollution
In order to solve the problem of high-rise water supply, some users use pipeline pumps to pump water directly, which will affect the water supply of other users around them due to the negative pressure, which violates the urban water supply management method

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing:

[0018] As shown in FIG. 1 , the tank body 3 is fixed on the base 11 , the side wall of the tank body 3 is provided with a water inlet 2 , the bottom is provided with a water outlet 10 , and the top is provided with a negative pressure valve 1 . The water outlet 10 is connected to the jellyfish pipe 8 through the through door 9 . A liquid level controller 4 is also arranged on the side wall of the tank body 3 , and the liquid level controller 4 is connected to the water pump 5 . The water outlet of the water pump 5 is connected to the user, and the water inlet is connected to the jellyfish pipe 8 through the water pump outlet check valve 6 and the water pump outlet gate valve 7 .

[0019] As shown in Figure 2, the non-negative pressure valve 1 includes a valve body 23, a valve core 13 and an outer cover 12. Inside the valve core 13, a floating ball 22, a sealing ring 21, a ...

Abstract

This invention relates to a suction-free tank including a base, a tank, an infall, an outfall and a pump characterizing in setting a suction-free valve at the top of the pump, the infall is connected with pipeline of tap water, the outfall is connected with the infall of the pump and the outfall of the pump is connected with users, in this case, inside of the tank always keeps positive pressure at any state.

Description

technical field [0001] The invention relates to a non-negative pressure tank, which belongs to the field of tap water supply equipment. Background technique [0002] At present, in the water supply system of high-rise buildings in cities and towns, water outlet pools or water storage tanks are generally used to store water, which are bulky, expensive, and easily cause secondary pollution. In order to solve the problem of high-rise water supply, some users use pipeline pumps to pump water directly, which will affect the water supply of other users around them due to negative pressure, which violates the urban water supply management method. Contents of the invention [0003] Based on the deficiencies of the prior art above, the technical problem to be solved by the present invention is to provide a non-negative pressure tank with small volume, low cost and convenient maintenance, installation and use. [0004] The technical solution adopted by this new model to solve its t...
