Description

Technical Field

[0001] The utility model relates to the technical field of voltage stabilization and purification, in particular to a small flow voltage stabilization and purification device. Background Art

[0002] Water is the source of life. In order for people to use water conveniently, a lot of water supply work is needed. Water supply refers to the provision of water resources through public facilities, commercial organizations, community efforts or individuals. Water is usually transported through pumps and pipes.

[0003] At present, the resistance of water supply pipelines increases with the use time, the stability of water pressure decreases, and the water directly supplied through the pipeline is often not drinkable directly, and needs to be purified accordingly. For this purpose, corresponding equipment is needed, and these equipment need to be inspected and maintained after long-term use. Once the inspection and maintenance work is carried out, the water supply pipeline needs to be completely disconnected, making it impossible for people to even meet simple water needs. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a small flow rate pressure stabilizing purification device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] Preferably, the pressurizer is a bladder-type expansion tank made of stainless steel, and the air chamber of the pressurizer is filled with nitrogen-stabilized gas.

[0009] Preferably, valve one, valve two, valve three, valve four and valve five are all brass ball valves.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Reference Figure 1-Figure 3A small flow rate pressure stabilizing purification device comprises an inlet pipe 1 and an outlet pipe 2. A water collector 3 is provided at one end of the inlet pipe 1, and a filter 17 is provided at one end of the outlet pipe 2. The filter 17 is a detachable precision filtering device. The filtration can meet the drinking water quality requirements and can be easily disassembled, which is very beneficial for the staff to carry out inspection and maintenance work. A stabilizer 4 is also provided on the inlet pipe 1. The stabilizer 4 is a bladder expansion tank made of stainless steel, and the air chamber of the stabilizer 4 is filled with nitrogen stabilizing gas, which can effectively buffer the pressure fluctuation of water. The stabilizer 4 and the filter 17 are connected by a connecting pipe 5, and the inlet pipe 1 and the outlet pipe 2 are connected by a bypass pipe 6. A valve 1 7 and a water stop valve 8 are provided at one end of the inlet pipe 1 close to the stabilizer 4, a valve 2 9 is provided on the bypass pipe 6, a valve 4 11 is provided on the connecting pipe 5, and a valve 5 12 is provided at one end of the outlet pipe 2 close to the filter 17. The end of the pipe 1 away from the water collector 3 is provided with a mounting pipe 15 through a detachable connecting piece 16, which makes it convenient for the staff to carry out disassembly and installation work. An auxiliary pipe 13 is provided between the water inlet pipe 1 and the water outlet pipe 2, and a drain pipe 14 is provided on the lower end surface of the auxiliary pipe 13. The water inlet pipe 1, the water outlet pipe 2, the connecting pipe 5, the bypass pipe 6, the auxiliary pipe 13 and the mounting pipe 15 are all 304 thin-walled stainless steel pipes with a diameter of DN15-25. This arrangement makes the device low-cost and can be used for a long time. A valve three 10 is provided on the drain pipe 14, so that when disassembling work is carried out, the water collector 3, the filter 17 and the stabilizer 4 and other structures can be drained, which is convenient for the staff to carry out subsequent inspection and maintenance operations. Valve one 7, valve two 9, valve three 10, valve four 11 and valve five 12 are all brass ball valves. The brass ball valve has a simple structure and is easy to operate, and can be used stably for a long time.

[0019] In the utility model, when the user uses the device, when the device is running, valve one 7, valve four 11, valve five 12 are opened, and valve two 9 and valve three 10 are closed; the installation pipe 15 supplies water to the water inlet 1 through the detachable connecting piece 16, and at this time, the water flows to the water-using equipment along the trajectory of the water inlet pipe 1, the pressure stabilizer 4, the connecting pipe 5, the filter 17 and the water outlet pipe 2, the air bag in the pressure stabilizer 4 is compressed to store the pressure, the water collector 3 stores the water inlet flow, and the water outlet pressure and flow are in a normal state. If the water inlet pressure and flow fluctuate, the device will process it. When the water inlet pressure is low, the air bag in the pressure stabilizer 4 expands to supplement the water outlet pressure. When the water inlet flow is low, the water collector 3 compensates; when the water inlet pressure is high, the air bag in the pressure stabilizer 4 compresses and stabilizes the water outlet , so that it can be ensured that the water output can remain stable, and the filter 17 can purify the water so that people can directly obtain drinkable water. When the device is overhauled and replaced, close valve one 7, valve five 12, and open valve three 10, so that water passes through the water inlet pipe 1 and the bypass pipe 6, and then enters the water outlet pipe 2. In this way, when the filter 17, the water collector 3, and the stabilizer 4 are disassembled, it can be ensured that people can still perform simple water collection work. During this process, the staff can open valve three 10, so that the residual water in the filter 17, the water collector 3, and the stabilizer 4 can be discharged through the auxiliary pipe 13 and the drain pipe 14, so that the subsequent overhaul and maintenance work can be better completed.

[0020] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
