Description

Pressure stabilizing water tank structure

Technical Field

The utility model relates to the technical field of pressure-stabilizing water tank manufacturing, in particular to a pressure-stabilizing water tank structure.

Background Art

Water supply pressure stabilizing devices are generally installed in long-distance water transmission and distribution pipelines, mainly to avoid negative pressure and water hammer in the pipeline network.

The pressure stabilizing devices commonly used in the prior art mainly act on the beginning of the pipeline, and include automatic exhaust valves, micro-resistance slow-closing check valves, air tanks, etc.

Therefore, when the terrain height difference is large, the pump head and flow rate are large, sudden pump stop and power failure are likely to generate negative pressure, that is, the water pressure elevation is lower than the terrain elevation, which will cause the following hazards:

1. It is easy to cause sewage backflow at the pipeline leakage point, polluting the water quality.

2. When the negative pressure is lower than the saturated vapor pressure, gas is generated, reducing the water-passing cross-section of the pipeline.

3. It is easy to cause water hammer and water pressure fluctuations, which are harmful to pipes and accessories.

Therefore, how to overcome the shortcomings of existing pressure-stabilizing water tanks, such as water quality being easily polluted, being unable to vent, and being prone to water hammer, and improve management efficiency has become a technical problem that technical personnel in this field urgently need to solve.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG1 is a schematic structural diagram of an embodiment of the utility model.

DETAILED DESCRIPTION

Example

As shown in FIG1 , the pressure-stabilizing water tank structure comprises a box-shaped water tank body 1, wherein the water tank body 1 is arranged at a height matching the pressure-stabilizing pressure, and is connected to the same water supply and distribution pipe 6 through a water inlet pipe 2 and a water outlet pipe 3;

The water inlet pipe 2 is provided with an electrically controlled water inlet valve 4 and a pressure gauge 7;

The water outlet pipe 3 is provided with an electrically controlled water outlet valve 5 and a one-way valve 8;

The electrically controlled water inlet valve 4 and the electrically controlled water outlet valve 5 are linked to each other. When the electrically controlled water inlet valve 4 is opened, the electrically controlled water outlet valve 5 is closed. When the electrically controlled water inlet valve 4 is closed, the electrically controlled water outlet valve 5 is opened.

The electrically controlled water inlet valve 4 and the electrically controlled water outlet valve 5 are both linked to the pressure gauge 7 and are opened or closed when the pressure gauge 7 collects a preset reading.

In actual application, when the water supply and distribution pipe 6 is cut off, the pressure gauge 7 is 0, and the water tank body 1 can quickly replenish water to the pipeline network through the water outlet pipe 3, avoiding the formation of negative pressure and bubbles in the pipeline network, thereby avoiding water pollution, reducing the flow cross-section of the pipeline, and overpressure damaging the pipeline and accessories.

When water enters the water tank body 1 through the water inlet pipe 2, the water enters the water tank body 1 at normal pressure to relieve the pressure in the pipe network, and when it flows out, it only carries the potential energy at the height of the water tank body 1, thereby achieving a pressure stabilization effect.

The water tank water inlet pipe 2 is provided with a pressure gauge 7, which can observe the pipe network pressure at any time. When the pipe network operating pressure is low, the water inlet pipe 2 can be closed according to the setting, and the pressure-stabilizing water tank stops running. When the pipe network runs at normal pressure, the electric-controlled water inlet valve 4 is opened to play a pressure-stabilizing role.

In some embodiments, the water tank body 1 is provided with a manhole and a vent pipe 9 at the top, a drain pipe 12 at the bottom, a disinfection device 10 inside, an overflow pipe 11 near the top of the side wall, and the outlet pipe 3 at the bottom;

The diameter of the ventilation pipe 9 is the same as the diameter of the water inlet pipe 2;

The diameter of the drain pipe 12 is one level smaller than the diameter of the water inlet pipe 2;

The disinfection device 10 is used to maintain the water quality of the water input into the water tank body 1;

The diameter of the overflow pipe 11 is one level larger than the diameter of the water inlet pipe 2;

The position where the water inlet pipe 2 is connected to the water tank body 1 is higher than the position where the overflow pipe 11 is provided on the water tank body 1 .

In actual applications, the water in the water tank will deteriorate due to long-term non-flow of water. The provision of the disinfection device 10 is beneficial to ensuring the water quality and avoiding secondary pollution of the passing water body, which would affect the water quality of water transmission and distribution.

When water enters the water tank body 1, water enters from the top of the water tank body 1, and the water inlet pipe 2 is located above the overflow pipe 11, which can prevent contact pollution.

In some embodiments, the manhole has a planar size of 800 mm×800 mm.

In some embodiments, the position where the water inlet pipe 2 is connected to the water tank body 1 is 10 cm higher than the position where the overflow pipe 11 is set on the water tank body 1.

In some embodiments, the ends of the water inlet pipe 2 and the water outlet pipe 3 connected to the water supply and distribution pipe 6 are connected to the same water diversion pipe 13 , and are connected to the water supply and distribution pipe 6 through the water diversion pipe 13 .

In actual applications, one end of the water inlet pipe 2 and the water outlet pipe 3 connected to the water distribution pipe 6 is connected to the same water diversion pipe 13, which is connected to the water distribution pipe 6 to form a combined structure of the water inlet pipe 2 and the water outlet pipe 3, which can reduce the amount of pipe materials and the cost.

In some embodiments, the water outlet pipe 3 is located between the end connected to the water supply and distribution pipe 6 and the electrically controlled water outlet valve 5, and the water inlet pipe 2 is located between the end connected to the water supply and distribution pipe 6 and the electrically controlled water inlet valve 4. A maintenance valve 14 is provided.

In practical applications, the electronically controlled water inlet valve 4 , the electronically controlled water outlet valve 5 and the water tank body 1 can be inspected by closing the inspection valve 14 .

In some embodiments, the water tank body 1 is provided with a liquid level valve; when the water level in the water tank body 1 reaches a preset height of the liquid level valve, the liquid level valve closes the water inlet pipe 2.

In practical applications, the level valve can be a float valve.

The water in the water tank is emptied due to stopping the pump. When the pump is started again, the liquid level valve automatically opens the water inlet pipe 2 to replenish water according to the water level in the water tank. When the water is replenished to the designed water level, it automatically closes and stops the water inlet.

The above describes in detail the preferred specific embodiments of the utility model. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
