Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b):

referring to fig. 1, the water-saving non-negative pressure water supply apparatus is described in this embodiment, and includes a steady flow tank 1, a pumping unit 2, and a negative pressure eliminator 3. The pump adding part 2 is placed on the ground on one side of the steady flow tank 1, and the pump adding part 2 is connected with the steady flow tank 1 through a water pipe. The negative pressure eliminator 3 is arranged at the top of the flow stabilizing tank 1, and the negative pressure eliminator 3 is communicated with the inside of the flow stabilizing tank 1.

Referring to fig. 1, the other side of the steady flow tank 1 is connected with a water filtering component 4 through a water pipe. The filter assembly includes a number of transition boxes 41. In the present embodiment, the number of the transition boxes 41 is three. The three transition boxes 41 are not communicated with each other. Two ends of the single transition box 41 are respectively connected with the steady flow tank 1 and the municipal water supply system through water pipes. The water flow finally enters the flow stabilization tank 1 through three non-communicating transition boxes 41. A first valve 42 is provided in the water line between the single transition box 41 and the municipal water supply. When the operator needs to clean the transition box 41. Only the corresponding first valve 42 of the transition box 41 that needs to be cleaned needs to be closed. The whole water supply system does not need to be shut down, and the normal operation of the system is ensured.

Referring to fig. 1 and 2, the water quality entering the ballast tank 1 is improved for the effect of filtering impurities in the water. Each transition box 41 is provided with a filter portion 5 inside. Meanwhile, each transition box 41 is provided with a fixing structure 6 inside, and each fixing structure 6 fixes the corresponding filter portion 5 inside the filter box. Fixed knot constructs 6 and includes two concave plate 61 and places the casing 62 of filter house 5, and casing 62 just is hollow out construction to the both sides of rivers flow direction, and two concave plate 61 length direction's one side is fixed respectively on the corresponding both sides of transition case 41 inner wall, and the opening of two concave plate 61 length direction one side is relative, and casing 62 both sides portion is located corresponding concave plate 61 respectively inside, the width of casing 62 and the inside width size looks adaptation of concave plate 61. The position of the housing 62 in the corresponding transition box 41 and thus the position of the filter house 5 is fixed by the two concave plates 61. The portion of the housing 62 that contacts the concave plate 61 is a unitary plate structure.

Referring to fig. 2 and 3, a plurality of placing grooves 7 are formed on two opposite sides of the concave plate 61 in the length direction. The plurality of placing grooves 7 on one side of the inside of the concave plate 61 are equidistantly arranged along the length direction of the concave plate 61. The ball 71 is movably placed on the placing groove 7. The cross section of the placing groove 7 is a major arc. The balls 71 are freely movable inside the placing groove 7. The balls 71 are partially located outside the placing groove 7. The balls 71 are in point contact with the inner wall side of the concave plate 61. When the operator takes the old housing 62, the friction force between the housing 62 and the concave plate 61 is reduced, so that the operator can conveniently replace the filter part 5, and the manual labor of the operator is reduced.

Referring to fig. 2, a first through hole 411 is formed in the top of the transition box 41, and a top cover 412 is fixed to the transition box 41 through a bolt at the first through hole 411. A handle 8 is fixed to the housing 62 near the center of the top 412. The operator can directly clean the inside of the transition box 41 by opening the top cover 412, which is convenient and fast. Handle 8 facilitates the operator lifting housing 62.

The implementation principle of the above embodiment is as follows: when an operator needs to clean one of the transition boxes 41. The operator closes the first valve 42 corresponding to the filter box to be cleaned. So that water in the municipal water supply does not flow into the transition box 41.

The operator then uses a tool to open the cap 412. After the top cover 412 is removed. The housing 62 is exposed to the air, and the operator pulls the handle 8 to separate the housing 62 from the concave plate 61.

Further, the operator cleans the inside of the transition box 41.

Finally, the operator inserts both ends of the new housing 62 in which the filter house 5 is placed into the corresponding concave plates 61. After the housing 62 is placed. The operator uses a tool to secure the top cover 412 to the transition box 41.

At this time, the transition box 41 is cleaned.

The operator opens the first valve 42 corresponding to the transition box 41 after being cleaned. The water flow in the municipal water supply system flows into the interior of the cleaned transition box 41 through the water pipe and finally flows into the interior of the surge tank.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
