Background

In the case of a water supply installation kit (herein referred to as "installation"), if a user suddenly closes a valve during operation, the flow rate of the liquid changes rapidly, and the instantaneous pressure within the water supply installation kit changes significantly, repeatedly, and rapidly, creating a water hammer that causes damage to the water supply installation kit, the pipes connected to the water supply installation kit, the pipe fittings, and the pipe installation.

For this purpose, check valves are provided on each outlet branch pipe, the number of check valves installed being the same as the number of branch pipes. Not only wastes time and labor and is not economical, but also does not protect the pipeline, the pipeline accessory and the pipeline equipment which are connected with the complete set of water supply equipment. The water hammer is used for driving the water hammer to rotate, the water hammer is driven by the water hammer to rotate, and the water hammer is driven by the water hammer to rotate.

Disclosure of Invention

The utility model aims to solve the problems in the prior art and provide a complete set of water supply equipment, only the water outlet of the water outlet manifold is provided with a non-return structure, which is beneficial to saving the cost of parts and the maintenance cost and improving the assembly and maintenance efficiency; the pipeline, the pipeline accessories and the pipeline equipment which are connected with the complete set of water supply equipment can be protected, and the damage caused by water hammer is reduced or even avoided.

The above technical purpose of the present invention is mainly solved by the following technical solutions: complete water supply equipment, including intake manifold, play water header pipe, a plurality of water pump, connect every the water inlet of water pump and the inlet branch pipe and the play water branch pipe of delivery port, the end of intaking of inlet branch pipe is connected on the intake manifold, the play water end of play water branch pipe is connected on the play water header pipe, its characterized in that the delivery port department of play water header pipe sets up non return structure. The non-return structure is only arranged at the water outlet of the water outlet collecting pipe, so that the part cost and the maintenance cost are saved, and the assembly and maintenance efficiency is improved; the pipeline, the pipeline accessories and the pipeline equipment which are connected with the complete set of water supply equipment can be protected, and the damage caused by water hammer is reduced or even avoided.

As further improvement and supplement to the above technical scheme, the utility model discloses a following technical measure: the water outlet end of the water outlet manifold pipe is provided with a cylinder, the inner end of the cylinder is provided with an inward-folded ring part, the inward-folded ring part and the outer wall of the water outlet manifold pipe form sealing fixed fit, and the check structure is arranged in the cylinder. Usually, the inner end of the cylinder is welded to the water outlet end of the water outlet manifold to form an integral structure.

The inner diameter of the cylinder is larger than that of the water outlet end of the water outlet collecting pipe. By adopting the non-return structure with proper size, the influence on the sectional area of the medium flowing channel in the water outlet gathering pipe is reduced, a better intercepting effect can be achieved, and the volume of the complete water supply equipment can be reasonable.

The outer end of the cylinder is provided with an outer flanging part which is matched with a flange plate, the flange plate is in water-tight fit with the outer flanging part, and the flange plate is used for limiting the check structure in the cylinder.

The flange plate is detachably connected with the outer flanging part through bolts. Meanwhile, the flange plate can be connected with a pipeline, a pipeline accessory or pipeline equipment.

The utility model discloses beneficial effect who has: the non-return structure is only arranged at the water outlet of the water outlet collecting pipe, so that the part cost and the maintenance cost are saved, and the assembly and maintenance efficiency is improved; the pipeline, the pipeline accessories and the pipeline equipment which are connected with the complete set of water supply equipment can be protected, and the damage caused by water hammer is reduced or even avoided.

Fig. 2 is a schematic cross-sectional view of fig. 1.

Fig. 3 is a schematic structural diagram of the present invention.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b): as shown in fig. 1-3, the complete set of water supply equipment comprises a water inlet manifold 2, a water outlet manifold 1, a plurality of water pumps 3, a water inlet branch pipe 4 and a water outlet branch pipe 5 which are connected to the water inlet and the water outlet of each water pump, wherein the water inlet end of each water inlet branch pipe is connected to the water inlet manifold, the water outlet end of each water outlet branch pipe is connected to the water outlet manifold, and the water outlet of the water outlet manifold is provided with a check structure 6. The non-return structure is only arranged at the water outlet of the water outlet collecting pipe, so that the part cost and the maintenance cost are saved, and the assembly and maintenance efficiency is improved; the pipeline, the pipeline accessories and the pipeline equipment which are connected with the complete set of water supply equipment can be protected, and the damage caused by water hammer is reduced or even avoided.

Preferably, in order to facilitate installation, a check structure is arranged, a cylinder 7 is arranged at the water outlet end of the water outlet manifold, an inner folded ring part 71 is arranged at the inner end of the cylinder, the inner folded ring part and the outer wall of the water outlet manifold form a sealing fixed fit, and the check structure 6 is arranged in the cylinder. Usually, the inner end of the cylinder is welded with the water outlet end of the water outlet collecting pipe to form an integral structure.

The inward-folding ring part 71 can be welded at the end part of the water outlet header pipe 1, can also adopt a threaded connection mode, and can be matched with a sealing ring to form water-tight connection, and can also adopt another flange plate matching mode to form connection.

The inner diameter of the cylinder is larger than that of the water outlet end of the water outlet collecting pipe. By adopting the non-return structure with proper size, the influence on the sectional area of the medium flowing channel in the water outlet gathering pipe is reduced, a better intercepting effect can be achieved, and the volume of the complete water supply equipment can be reasonable. In other words, the check structure 6 adopts a stop valve or a check valve, and the cross section of the inner cavity of the check structure 6 is at least matched with the inner diameter of the water outlet collecting pipe, so that the influence on the flow speed of the medium is reduced.

The outer end of the cylinder has an out-turned collar 72 which engages a flange 8 for retaining the non-return structure within the cylinder. The flange is in fluid-tight engagement with the outer collar portion and a sealing ring 9 is normally provided between the outer collar portion 72 and the flange 8.

The flange plate is detachably connected with the outer flanging part through bolts.

Meanwhile, the flange plate can be connected with a pipeline, a pipeline accessory or pipeline equipment.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention.
