Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: flow regulator, including flow regulator main part 1 and device base 2, 1 fixed mounting of flow regulator main part is in the upper right side of device base 2, and the upside fixed mounting of flow regulator main part 1 has vacuum inhibitor 3, the downside fixed mounting of flow regulator main part 1 has variable frequency constant voltage water supply equipment 5, constitute complete pipe network no negative pressure water supply equipment with this, flow regulator main part 1 includes jar body 6, water inlet 7 and vacuum inhibitor interface 8 have been seted up respectively to the front and back both sides of the last lateral wall of jar body 6, and the even welding of the downside of jar body 6 has delivery port 10, the inside fixed mounting of jar body 6 has pressure sensor 15 of being connected with the external control cabinet electricity, variable frequency constant voltage water supply equipment 5 is the water supply equipment that forms through three butterfly valves of external control cabinet control, water pump and check valve subassembly combination.

Specifically, the inner cavity of the tank 6 is divided into a high-pressure cavity 12, a constant-pressure cavity 11 and a low-pressure cavity 13 from the back to the front, the constant-pressure cavity 11 is communicated with the vacuum suppressor 3, the vacuum suppressor 3 is communicated with the high-pressure cavity 12 and the low-pressure cavity 13 through an internal pipeline, and an electromagnetic valve 14 electrically connected with an external control cabinet is fixedly installed between the vacuum suppressor 3 and the high-pressure cavity 12.

Specifically, the upper flange of the water inlet 7 is connected with a low-resistance through-type filter 4, the upper end of the low-resistance through-type filter 4 is communicated with a water supply line, and the low-resistance through-type filter 4 plays a role in filtering impurities in water.

Specifically, negative pressure gauges 9 are fixedly mounted on the outer sides of the low-resistance straight-through filter 4 and the tank 6, and the negative pressure gauges 9 are pressure gauges for the water pressure in the reaction tube.

The working principle is as follows: when the utility model discloses when using, this equipment is direct from municipal pipe network water intaking, and the water piping connection is in water inlet 7 department, and the running water gets into flow regulator main part 1 through low resistance through-type filter 4, and the constant pressure intracavity 11 internal gas passes through vacuum suppressor 3 and compresses to low pressure chamber 13, and after the constant pressure intracavity 11 internal water was full, 3 self-closing of vacuum suppressor, constant pressure chamber 11 and low pressure chamber 13 are totally enclosed structure not with the outside air contact. After the constant pressure cavity 11 is full of water, the pressure sensor 15 of the water inlet 7 detects that the inlet pressure is higher than the protective pressure, the equipment starts the system to operate automatically, after the equipment operates, the system detects the water pressure through the pressure sensor of the water outlet of the equipment, the detected value is compared with the set value, the automatic system controls the number and the operating frequency of the operating water pumps, the rotating speed of the operating water pumps is adjusted to realize the constant-pressure and constant-flow water supply of the system, and the equipment utilizes the original pressure of the municipal pipe network to the maximum extent.
