Description

Technical Field

[0001] The utility model belongs to the technical field of water supply equipment, and more specifically, particularly relates to a box-type pre-pressurized non-negative pressure water supply equipment. Background Art

[0002] The box-type non-negative pressure water supply equipment can be directly connected to the water supply network to ensure that the water supply network does not generate negative pressure. During peak hours, the water in the closed water tank will be pressurized to compensate for the insufficient water supply of the water supply network and meet the water needs of users. The equipment is mainly composed of a closed water tank, a main pump unit, a frequency conversion control cabinet, a pressurizing device, a water diversion device, a steady flow tank, a non-negative pressure flow controller, a pressure maintaining device and a pressure sensor, etc., and when supplying water to the inside of the closed water tank, it is mostly controlled by a ball valve structure. However, based on the prior art, it is found that when the existing box-type non-negative pressure water supply equipment is in use, its ball valve structure is usually connected to the inside of the closed water tank through a round rod connected to the ball float and then rotated. However, due to the large internal space of the water tank, the water surface is prone to fluctuations after water inlet, which makes it easy to cause oblique push on the ball valve during water filling, causing the round rod to bend obliquely due to the fluctuation of the water surface, and then easily causing damage to the ball valve structure.
